In this embodiment, one hoistway 7 is provided with, for example, three cars 1a, 1b, 1c.

A high floor main rope 2a for pulling the high floor car 1a, a high floor balancing weight 6a coupled to the main rope 2a and balanced with the high floor car 1a, and a drive J driven by the high floor hoist 3a. The upper U-shaped rope drive system is configured with the high floor sheave 4a around which the high floor main rope 2a is wound, and the high floor car 1a is raised and lowered in the hoistway 7. The elevation of the high-floor car 1a is controlled by driving the high-floor hoist 3a by a control device (not shown). The same applies to middle and low floors.

In addition, the rope drive system for the middle floor is superimposed on the rope drive system for the lower floor so as to cover the rope drive system for the middle floor in the ascending and descending direction without contact. Furthermore, a rope drive system for a higher floor is overlapped thereon so as to cover in an ascending and descending direction without contact. For this reason, the inverted U-shaped bulge spreads as the rope drive system is located above the overlap of the piled rope drive systems.

When this elevator apparatus is installed, the elevator direction of the car 1 is the Z direction, and the direction orthogonal to the Z direction in the plane where the car 1, the main ropes 2, and the counterweight 6 are empty, for example, the direction of entering and exiting the car 1 is the Y direction. , Y, and Z are defined as X directions, and a plane formed by an inverted U-shaped rope drive system is defined as a moving plane. Further, the side with the door of the car 1 is the front face, the side with the counterweight 6 is the rear face, the YZ plane is the side face, the upper part in the Z direction of the car is the upper face, and the lower part is the lower face.

Also, in FIG. 1, FI indicates a boarding floor serving as a reference for people and cargo, FH indicates a high floor, FM indicates a middle floor, and FL indicates a low floor.

で は In this embodiment, for example, the moving planes of the rope drive system on the high floor, the middle floor, and the low floor are almost the same plane.

FIG. 2 shows a schematic top view of the elevator apparatus. The size of the car is such that the lower car is larger than the upper car, and when a plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane, at least The part that joins the cords protrudes from the upper cage.

When the trajectory of the movement of the balance weight of the rope drive system is defined as a movement line, all of the movement lines of the plurality of balance weights 6a, 6b, 6c of the rope drive system constitute a substantially flat surface. A plane parallel to the Z axis is formed.

Further, at least one of the plurality of rope drive systems, for example, the turn-back position of the high-rise main rope 2a is arranged at a position where the entire up-and-down stroke (FL, FM, FH) of the hoistway 7 can be moved. The turn-back position of the rope drive system, for example, the middle floor main rope 2b is arranged at a position where a part (FL, FM) of the entire up-and-down stroke can be moved. In addition, for example, the turn-back position of the lower floor main rope 2c is arranged at a position where a part (FL) of the entire up-and-down stroke can be moved.

ロ ー プ Each of the rope drive systems for the lower floor, the middle floor, and the higher floor has almost the same configuration as the conventional one, and the operation will be described below.

Each sheave 4a, 4b, 4c is rotated by a respective hoist 3a, 3b, 3c, and power is transmitted by traction with the main ropes 2a, 2b, 2c wound around the sheaves 4a, 4b, 4c. Is done. The cars 1a, 1b, 1c and the counterweights 6a, 6b, 6c are guided by the guide rail 8 via guide shoes (not shown) provided on the respective cars 1a, 1b, 1c and the counterweights 6a, 6b, 6c. The cars 1a, 1b, and 1c vertically move up and down along the guide rails 8. The elevators of the respective cars are operated by controlling the driving of the hoists 3a, 3b, 3c by respective control devices (not shown).

When a plurality of rope drive systems are arranged in one hoistway 7 as in this embodiment, the arrangement of the hoists 3a, 3b, 3c and the roping of the main ropes 2a, 2b, 2c become complicated. This configuration will be described.

In the configuration as shown in FIG. 1, the uppermost rope drive system for the upper layer does not matter, but for the middle and low layers, the main rope 2 passes through the hoistway 8 and does not contact the upper car 1. Must be placed.

Therefore, in this embodiment, when the size of the car 1 is changed as shown in FIG. 2 and projected on the XY plane, the connection positions of the car 1b for the middle floor, the car 1c for the lower floor, and the main ropes 2b, 2c are sequentially determined. It is shifted backward. For this reason, the car 1 or a part of the car is protruding, and the middle floor main rope 2b and the low floor main rope 2c are configured to pass through the rear surface of the high floor main rope 2a.

Further, an operation system of the elevator apparatus according to the present embodiment will be described below. In this embodiment, three rope drive systems are configured to service zones of a high floor (FH), a middle floor (FM), and a low floor (FL).

FIG. 3 is an explanatory diagram showing an example of an operation system when performing the zoning service according to the present embodiment. In this example, it is assumed that there are no elevator users, and it is assumed that there are no elevator users. The operation procedure is shown below.

The high-floor car 1a operates in the order of boarding (t1) → going express operation (t2) → each floor service (t3, t4) → returning express operation (t5).

The car 1b for the middle floor operates in the order of car 1a departure waiting (t1) → boarding (t2) → going express operation (t3) → service on each floor (t4) → return express operation (t5).

The lower floor car 1c operates in the order of car 1a, car 1b departure waiting (t1, t2) → boarding (t3) → service on each floor (t4) → return express operation (t5).

In this embodiment, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner in one hoistway, and a plurality of cars are independently provided in one hoistway. In addition, since the vehicle can be safely and stably operated and the transport amount per hoistway area can be increased, the total plane space of the hoistway can be reduced.

In particular, as shown in FIG. 1, deflecting wheels 5a and 5b are provided so as to cover a plurality of inverted U-shaped rope drive systems in one hoistway so as to be able to ascend and descend without contacting each other. , 5c are shifted rearward so that the main ropes 2a, 2b, 2c do not come into contact with each other. Also, by changing the size of the car, the connecting portion between the main rope 2b for the middle floor and the car 1b for the middle floor is shifted to the rear of the connecting portion between the main cable 2a for the high floor and the car 1a for the high floor. The connecting portion between the lower floor main rope 2c and the lower floor car 1c is shifted to the rear of the connecting portion for the middle floor. For this reason, the main ropes 2 can be raised and lowered smoothly, and the size of the lower car is made larger than the size of the upper car, so that the capacity (capacity) of the lower car 1 increases, and in fact many There is also an effect that the lower floors that are considered to be used by people can transport more people.

Further, since the moving planes of the plurality of rope drive systems are substantially one plane in the YZ plane, the moving lines of the three counterweights 6a, 6b, 6c are arranged substantially in one plane in the Y direction at the rear of the car. Can be configured. Therefore, the counterweights 6a, 6b. The guide 6c can also be used and can be made compact, and the device can be made compact.

全 Further, the entire up-and-down stroke of the hoistway 7 is divided into a plurality of zones, and the zones are sequentially allocated from the top of the car to the zones, and the cars are simultaneously operated in each zone. For this reason, many passengers can be raised and lowered on one hoistway 7, and zone service conventionally performed on a plurality of hoistways can be performed on one hoistway. For example, at the time of going to work in the morning as shown in FIG. 3, it is possible to transport about 2.5 times as many people as in the past.

Embodiment 2 FIG.
Hereinafter, an elevator apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. FIG. 4 is a perspective view schematically showing an elevator apparatus according to Embodiment 2, FIG. 5A is a top view, and FIG. 5B is a side view.

In this embodiment, three U-shaped moving planes of the rope drive systems are connected to each other. They were configured almost parallel. Since the moving planes are parallel to each other, the two rope drive systems do not contact each other even if the inverted U-shaped bulges of the rope drive system for the lower floor and the rope drive system for the middle floor are the same. The bulge of the inverted U-shape of the rope drive system for higher floors is larger than the lower two.

FIG. 6 is an enlarged perspective view showing the rear portions of the cars 1a, 1b, and 1c. In the drawing, 15a is a cutout provided at the rear two corners of the high-floor car 1a, and 15b is a middle-floor car 1b. A notch provided at one corner of the rear part.

When the plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane by the cutouts, at least a portion of the lower car that connects the main ropes projects more than the upper car. Therefore, the main ropes connected to the lower car can pass through the notches 15a and 15b without contacting the upper car.

In this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in a single hoistway so as to cover each other in a non-contact manner. Since a plurality of cars can be operated independently and safely and stably, and the transport volume per hoistway area can be increased, the total plane space of the hoistway can be reduced.

Further, since the moving planes of the plurality of rope drive systems are substantially parallel to each other, the moving lines of the three counterweights 6a, 6b, 6c are arranged substantially on one plane in the X direction at the rear of the car. And the counterweights 6a, 6b. The guide 6c can also be used and can be made compact, and the device can be made compact. Further, in a limited space, the interval between the rope drive systems can be widened, and the risk of contact between the main ropes 2 can be reduced.

In addition, if a plurality of rope drive systems are arranged in this way, the hoist and the sheaves 4a, 4b, 4c can be easily arranged.

Embodiment 3 FIG.
Hereinafter, an elevator apparatus according to Embodiment 3 of the present invention will be described with reference to the drawings. FIG. 7A is a top view schematically showing an elevator apparatus according to Embodiment 3, and FIG. 7B is a side view.

In one hoistway, a plurality of inverted U-shaped rope drive systems are overlapped so as to cover each other in a non-contact manner. In this embodiment, each of the three U-shaped moving planes formed by the inverted U-shaped rope drive systems Are arranged so as to be substantially parallel to the Z axis and to have each of the moving planes intersect with each other. Further, with this configuration, even if the rope drive system for the lower floor and the rope drive system for the middle floor have the same U-shaped bulge, the two rope drive systems do not come into contact with each other. The bulge of the inverted U-shape of the rope drive system for higher floors is larger than the lower two.

Further, a notch is provided at the rear of the lower car so that the main rope connected to the lower car can pass without contacting the upper car, as in the second embodiment. is there.

In this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in a single hoistway so as to cover each other in a non-contact manner. Since a plurality of cars can be operated independently and safely and stably, and the transport volume per hoistway area can be increased, the total plane space of the hoistway can be reduced.

Further, since the moving planes of the plurality of rope drive systems are made to intersect each other, the moving lines of the three counterweights 6a, 6b, 6c are arranged substantially on one plane in the X direction at the rear of the car. The counterweights 6a, 6b. The guide 6c can also be used and can be made compact, and the device can be made compact.

れ ば In addition, if a plurality of rope drive systems are arranged as described above, the hoist and the sheaves 4a, 4b, 4c are separated from each other and are easily arranged.

Embodiment 4 FIG.
Hereinafter, an elevator apparatus according to Embodiment 4 of the present invention will be described with reference to the drawings. FIG. 8A is a perspective view schematically showing an elevator apparatus according to Embodiment 4, FIG. 8B is a top view, and FIG. 8C is a side view.

In one hoistway, a plurality of inverted U-shaped rope drive systems are overlapped so as to cover each other in a non-contact manner. In this embodiment, each of the three U-shaped moving planes formed by the inverted U-shaped rope drive systems Are configured to be substantially parallel to the Z axis and orthogonal to at least one of the moving planes. For example, in this embodiment, the moving plane of the rope drive system for the high floor is the YZ plane, and the moving plane of the rope drive system for the middle floor and the low floor is the XZ plane orthogonal to the YZ plane. Accordingly, the place where the high-floor counterweight 6a moves is located at the rear, and the place where the middle-floor counterweight 6b and the low-floor counterweight 6c move are arranged on the side. By arranging the counterweight separately on the rear surface and the side surface of the car 1 in this manner, a large margin for arranging the main rope 2 can be obtained, a rope drive system can be easily configured, and the depth direction of the elevator apparatus can be reduced.

In this embodiment, the moving plane of the high floor rope drive system is the YZ plane, and the high floor counterweight 6a is disposed on the rear surface of the car 1. However, the present invention is not limited to this. The movement plane of the system may be the YZ plane, and the counterweight 6 may be disposed on the rear surface of the car 1.

Further, in the second and third embodiments, a notch is provided at the rear of the lower car 1 so that the main rope 2 coupled to the lower car 1 can pass through without contacting the upper car 1. However, in this embodiment, as shown in FIG. 8A, the three cars 1 are made to have the same shape, and the joint between the car 1b for the middle floor and the main rope 2 of the car 1c for the low floor is projected. Are provided with connecting portions 16b and 16c. For this reason, the main rope 2 connected to the lower car 1 can pass through without contacting the upper car 1.

In this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are configured so as to be in non-contact with each other in one hoistway. Each car can be operated independently and safely and stably, and the transport volume per hoistway area can be increased, so that the total plane space of the hoistway can be reduced.

れ ば In addition, if a plurality of rope drive systems are arranged as described above, the hoist and the sheaves 4a, 4b, 4c are separated from each other and are easily arranged.

Embodiment 5 FIG.
FIG. 9 is an enlarged perspective view showing the rear surface of the car 1 of the elevator apparatus according to Embodiment 5 of the present invention.

In this embodiment, the connecting portions 16b and 16c are provided so that the connecting portion between the car 1b for the middle floor and the main rope 2 of the car 1c for the low floor protrudes. Further, since the connecting portions 16b and 16c are both provided on the rear surface of the car, they are shifted in the X direction so that the main ropes 2b and 2c do not come into contact with each other.

Therefore, the main ropes 2 connected to the lower car 1 can pass through without contacting the upper car 1.

Also, in the configuration shown in FIG. 1, the lower car is shifted behind the upper car in order to prevent the main ropes from contacting with each other, but they may be shifted left and right.

Further, as shown in the second and third embodiments, at least a part of the upper car may be cut away, and when a plurality of cars arranged in the hoistway are projected on the XY plane, the lower car may be cut off. A similar effect can be achieved if at least the portion connecting the main ropes is configured to protrude from the upper car.

Furthermore, the car may have a through-passage so that the main rope can pass near the center of the car.

Embodiment 6 FIG.
Hereinafter, an elevator apparatus according to Embodiment 6 of the present invention will be described with reference to the drawings. FIG. 10 is a configuration diagram showing an elevator apparatus according to Embodiment 6. In the drawing, reference numeral 20 denotes a counterweight that also serves as a component of the linear motor, and reference numeral 21 denotes a counterweight guide that also serves as a component of the linear motor. The balance weight 20 and the balance weight guide 21 constitute a motor, and the balance weight 20 is connected to the main rope 2. The other components are the same as those in FIG. 1. In this embodiment, in particular, for example, the rope driving system for the middle floor and the rope driving system for the low floor are constituted by the counterweights 20b and 20c and the counterweight guides 21b and 21c. Using a linear motor.

In this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in a single hoistway so as to cover each other in a non-contact manner. Since a plurality of cars can be operated independently and safely and stably, and the transport volume per hoistway area can be increased, the total plane space of the hoistway can be reduced.

In the first embodiment, when the hoisting machines 3a, 3b, and 3c are arranged at the upper part, the size of the hoisting machine is large, and therefore, the machine room in which the hoisting machine above the hoistway 7 is placed becomes large. Would. On the other hand, if a linear motor is used, the parts using the hoisting machines 3b, 3c and the sheaves 4b, 4c in Embodiment 1 can be deflected to the sheaves 5b, 5c, so that the size of the machine room can be reduced, The hoistway 7 can be made smaller. In particular, it is effective in a configuration in which a plurality of rope drive systems are overlapped.

Embodiment 7 FIG.
Hereinafter, an elevator apparatus according to Embodiment 7 of the present invention will be described with reference to the drawings. FIG. 11 and FIG. 12 are explanatory views showing one car part in an enlarged manner. Since the main cable 2 in the conventional elevator apparatus can be arranged at the position of the center of gravity of the car 1, no moment is generated even if the car 1 is pulled up by the main cable 2. However, in the middle and low-rise main ropes 2b and 2c in the first to sixth embodiments, the car 1 may have to be eccentrically attached to the car 1 in order to avoid the car 1a above. When the main rope 2 is eccentrically attached to the car 1, a moment in the -θX direction as shown by an arrow A in FIG. 11 is generated when the car moves up and down, and the car 1 may be inclined.

Therefore, in this embodiment, a car inclination suppressing mechanism is provided to correct a moment due to eccentricity. For example, as shown in FIG. 12, a balance weight 22 for correcting the weight of the car 1 with respect to the position of the main rope 2 is provided.

When the car 1 is pulled up and down by pulling the main rope 2, a moment in the -θX direction as shown by an arrow A is generated, and the car 1 tends to tilt. However, since the balance weight 22 is provided on the rear surface of the car 1, a moment corresponding to the weight of the balance weight 22 is generated in the direction B in which the moment A is canceled. For this reason, it can suppress that the car 1 inclines.

Embodiment 8 FIG.
Hereinafter, an elevator apparatus according to Embodiment 8 of the present invention will be described with reference to the drawings. This embodiment is a modified example of the car inclination suppressing mechanism, and FIG. 13 is an explanatory diagram showing an enlarged part of one car. Reference numeral 23 denotes a reinforcing guide shoe that guides the car along the guide rail 8, and is disposed at a position where the guide rail 8 intersects the guide rail 8.

The guide shoe 23 is normally provided between the car 1 and the guide rail 8, and the reinforced guide shoe 23 is disposed at a position facing a moment generated when the vehicle is towed, and is reinforced to support the moment. It is. That is, when the car 1 is moved up and down by the main rope 2, a moment A in the -θX direction is generated. Therefore, the reinforcing guide shoes 23 are provided on the upper left and lower right to support the moment A. For this reason, the moment A due to the eccentricity is supported by the guide shoe 23, and the car 1 can be prevented from tilting.

If necessary, the existing guide shoe may be provided as it is.

Embodiment 9 FIG.
Hereinafter, an elevator apparatus according to Embodiment 9 of the present invention will be described with reference to the drawings. This embodiment is a modified example of the car inclination suppressing mechanism, and FIG. 14 is an explanatory diagram showing an enlarged part of one car. 25 is a moment compensation link, for example, a parallel link. That is, a combination of four-node links using a parallelogram is used. In this method, a two-stage four-node link is constituted by 25a to 25g, the left pin portions 26a and 26b are joined together with a car, and the right shoe portions are provided with guide shoes 23a and 23b. And is in contact with the guide rail 8 which is a fixed portion. A guide shoe 23c connected to the car 1 is provided on the opposite side of the parallel link 25 with respect to the guide rail 8. Similarly to the eighth embodiment, the guide shoes 23a, 23b, and 23c are arranged at positions facing the moment generated when the vehicle is towed, and are reinforced to support the moment.

With this configuration, the parallel link 25 keeps the car 1 parallel even if the car 1 is inclined by the moment force A. For this reason, the inclination force is converted into a pressing force on the guide rail 8 via the guide shoes 23a and 23b. Accordingly, the car 1 attempts to move in the −Y direction in this state, but this is supported by the guide shoe 23c so as not to move.

In this way, the parallel link 25 constitutes a car inclination preventing mechanism, and the car 1 stably moves up and down without being inclined even if the connecting portion between the main rope 2 and the car 1 is eccentric with respect to the center of gravity of the car 1 be able to.

モ ー メ ン ト Further, since the moment compensating link 24 is light and can be realized, it is suitable for practical use.

Further, in the configuration in which the moment force A is directly supported by the guide shoe 23 as in the eighth embodiment, a moment force A is applied to the guide rail 8, and a force is further applied to the building to which the guide rail 8 is fixed via the guide rail 8. I will. However, with the configuration as in this embodiment, the pressing force of the guide shoes 23a and 23b against the guide rail 8 is supported by the guide shoe 23c disposed between the guide shoes 23a and 23b. No effect is exerted on the building supporting the guide rail 8. In addition, running becomes stable.

In addition, in the eighth embodiment, since the inclination of the car 1 is determined by the positional accuracy of the guide shoe 23 sandwiching the guide rail 8, a high positional accuracy is required for mounting the guide shoe 23. According to this, the link mechanism can be contracted in the parallel direction (Y direction) and supported by the guide shoe 25c, so that high mechanical precision is not required and the cost can be reduced.

Guide shoes 23 a and 23 b are attached to the right pin portion, and are in contact with the guide rail 8. A guide shoe 23c coupled to the car 1 is provided on the opposite side of the guide rail 8 therebetween.

With this configuration, as in the ninth embodiment, even when the car 1 is inclined by the moment force A, the car 1 is kept parallel by the X-link 25 and the force to be inclined is guided by the guide shoes 23a and 23b. It is converted into a pressing force on the rail 8. Accordingly, the car 1 attempts to move in the −Y direction in this state, but this is supported by the guide shoe 23c so as not to move.

With this configuration, similarly to the ninth embodiment, the X link 25 constitutes a car inclination preventing mechanism, and even if the connecting portion between the main rope 2 and the car 1 is eccentric with respect to the center of gravity of the car 1, the car 1 Can be moved up and down stably without tilting. In addition, no torsional force acts on the guide rail 8, the influence on the building supporting the guide rail 8 can be reduced, and the mechanical accuracy can be reduced. Further, since the number of parts of the link mechanism is smaller than that in the ninth embodiment, there is an effect that the cost can be reduced.

In the figure, a rope drive system for a higher floor has the same configuration as that in the first embodiment. The rope drive system for the middle floor turns the main rope 2b under the car 1b and forms a 2: 1 roping that supports the car 1b from below on both sides via the deflecting wheel 5b. In addition, the low-rise car 1c does not constitute a rope drive system, but uses a hydraulic elevator 28 that lifts the car 1c from below by hydraulic pressure.

ロ ー プ The rope drive system for the middle floor in this embodiment shows another embodiment in which the car 1 is supported by the main ropes 2 on both sides. If the main cable 2b is turned under the car 1b and supported on both sides of the car 1b from below, it can be driven without generating a moment.

Furthermore, since the low-floor car 1c is configured using a hydraulic elevator that is lifted by hydraulic pressure, there is no interference between the high-floor car 1a, the middle-floor car 1b, and the low-floor rope drive system.

Passengers can board the car from the car floor corresponding to the floor they want to go to. In this case, boarding of the three cars can be started at the same time, and when the boarding of the three cars is completed, the three cars can start operating at the same time. Therefore, as in the operation in the first embodiment shown in FIG. 3, it is necessary to wait at t2 to get into the middle-floor car 1b or at t3 to wait to get into the low-floor car 1c. And the multi-transport efficiency can be further improved.

In this embodiment, a plurality of floors are connected by stairs at the first floor and a standard boarding floor. However, the present invention is not limited to this. What is necessary is just to comprise.

Embodiment 16 FIG.
Hereinafter, an elevator apparatus according to Embodiment 16 of the present invention will be described with reference to the drawings.
The present invention includes a plurality of cars in one hoistway, and each of the cars is independently movable. When operating a car having such a configuration, it is necessary to take measures in terms of safety, which were not necessary in the past.

This embodiment is for safe operation. FIG. 22 is a flowchart illustrating an example of control at the start of car movement according to the sixteenth embodiment. This control can be executed by, for example, a control device that controls the hoisting machine 3.

First, in step ST1, it is determined whether there is another car 1 in the moving direction of the car to be controlled. If there is no other car 1, movement of the car to be controlled is started in step ST4. If there is another car in the movement direction in the determination in step ST1, it is determined in step ST2 whether the distance between that car and the car to be controlled is within a certain distance. The distance between the cars can be known from the operating states of the hoisting machine controlled by the control device and the hoisting machines of other cars. Also, the fixed distance is a distance that is sufficiently safe even if the car to be controlled starts moving, and various cases can be considered according to the moving speed, for example, when the emergency stop is operated at that speed It is set to the braking distance.

は If the distance between the cars is greater than a certain distance in step ST2, it is considered safe to start the movement, and the movement of the car to be controlled is started in step ST4. If the distance between the cars is within a certain distance in step ST2, the process waits for time in step ST3 and repeats the determination again in step ST2.

As described above, it is determined whether or not the car can be moved before the start of the movement, and control is performed so that the movement is not started when the distance of another car in the moving direction of the car is less than a certain distance. Thus, even if a plurality of cars are provided in one hoistway, the car can be operated safely and an elevator apparatus with high transportation efficiency can be obtained.

Embodiment 17 FIG.
Embodiment 17 Hereinafter, an elevator apparatus according to Embodiment 17 of the present invention will be described with reference to the drawings. As in the sixteenth embodiment, this embodiment is designed to avoid collision between cars and to operate safely.

FIG. 23 is an enlarged perspective view showing a car 1a for a high floor and a car 1b for a middle floor of the elevator apparatus according to Embodiment 17. In the figure, reference numeral 30 denotes a distance measuring device that measures the distance between cars without contact using, for example, a laser.

The distance measuring device 30 is provided on the car 1b for the middle floor, emits laser light upward, receives the laser light reflected by the car 1a for the upper floor located above, and measures the distance based on the time difference. Is what you do.

In the sixteenth embodiment, the distance between the cars is obtained by calculating information from the hoist by the control device, and the safe operation is controlled based on this value. In this embodiment, the distance between the cars is further measured by the distance measuring device 30. The safety at the start of the movement of the car is monitored based on the flowchart of FIG. Since the distance between the cars is actually measured by providing the distance measuring device 30, the reliability is improved instead of relying only on the value calculated by the control device.

In the above embodiment, the distance measuring device 30 using a laser is used. However, the present invention is not limited to this. For example, a device that measures the distance using ultrasonic waves or magnetism may be used. Instead of a non-contact distance measuring device, for example, a direct distance measuring unit that connects the cars with a wire may be used. Further, a configuration in which a linear scale is provided on the guide rail 8 or the hoistway 7 may be used.

Embodiment 18 FIG.
Hereinafter, a method for controlling an elevator apparatus according to Embodiment 18 of the present invention will be described. This embodiment controls the moving speed of the car 1 corresponding to the distance and the relative speed between the adjacent cars 1 in order to safely operate the elevator apparatus having a plurality of cars on one hoistway. It is.

As shown in the sixteenth embodiment, the distance and the relative speed between the cars 1 can be obtained by calculating from the information of the hoist by the control device, or by measuring with the distance measuring device 30 provided in the car. .

FIG. 24 is a flowchart showing an example of the control at this time. In normal operation, a speed pattern of acceleration, constant speed, and deceleration is set in advance as the rated traveling speed of the car 1. A certain car 1 starts moving, and starts rated traveling in step ST11. In step ST12, the distance between adjacent cars is calculated from the hoisting state of the hoisting machine 4. Further, in step ST13, the relative speed between cars of adjacent cars is calculated from the hoisting state of the hoisting machine 4. Based on the relative speed between the cars, a safe distance between the cars is calculated at the relative speed (step ST14).

Next, in step ST15, the actual distance between the cars obtained in step ST12 is compared with the safety distance from the relative speed obtained in step ST14. If the actual distance between the cars is large, the rated traveling is commanded in step ST16. I do.

安全 The safety distance from the relative speed obtained in step ST14 is compared, and if the actual distance between the cars is small or equal, it is determined that there is danger, and in step ST17, the car is decelerated so that the relative speed becomes small.

In the above embodiment, when calculating the distance between cars and the relative speed between cars, calculation is performed from the hoisting state of the hoist. However, the present invention is not limited to this. The same effect can be obtained by measuring with a sensor.

Further, in this embodiment, the moving speed of the car is controlled according to both the distance between the adjacent cars and the relative speed thereof, but the movement of the car is controlled according to either the distance between the adjacent cars or the relative speed thereof. The moving speed may be controlled.

As described above, since the moving speed of the corresponding car 1 is controlled according to the distance and the relative speed between the adjacent cars 1, the elevator device can safely operate even if a plurality of cars are provided in one hoistway. it can.

In particular, in normal operation, the vehicle is running at rated speed.However, even if the distance between adjacent cars approaches or the speed of the car becomes abnormal for some reason during operation, the car according to this embodiment By controlling the moving speed of the vehicle, it is possible to operate safely and efficiently.

Embodiment 19 FIG.
Hereinafter, a control method according to an elevator apparatus according to Embodiment 19 of the present invention will be described. As shown in the sixteenth embodiment, the distance between the cars can be obtained by calculating from the information of the hoist by the control device or by measuring with the distance measuring device 30. The safety at the time of starting the movement of the car is monitored using the distance between the cars based on the flowchart of FIG.

In this embodiment, not only at the time of starting the movement of the car, for example, when the distance between the cars approaches a dangerous distance due to the braking force of the car for some reason during operation, the control is switched to the emergency operation mode. I do.

FIG. 25 is a flowchart showing an example of the control at this time. In step ST31, for example, the distance of the upper car is detected by the control device or the distance measuring device 30. In step ST32, it is determined whether the distance between the cars is within a certain distance. The certain distance at this time is a distance at which the distance between the cars is dangerous from the viewpoint of the braking force of the car, and is set, for example, to the height of the car. If it is determined that the distance is equal to or longer than the predetermined distance, it is within the safe range, and the operation is continued in step ST33.

場合 If it is within a certain distance in the judgment of step ST32, it is regarded as a dangerous range, and the mode is switched to the emergency operation mode. That is, both cars are decelerated urgently in step ST34, and if there is a shelter nearby, they are evacuated (steps ST35 and ST36). If there is no evacuation area nearby, the operation of all cars is stopped in step ST37 because danger avoidance is impossible and an emergency situation occurs. In the case of refuge, when the danger is avoided, it is possible to operate normally again.

According to this embodiment, in a case where one hoistway has a plurality of cars, even if the distance between the cars approaches a dangerous distance for some reason, danger can be avoided, and safety can be improved. There is an effect that a high elevator device can be obtained.

Embodiment 20 FIG.

FIG. 26 is an enlarged perspective view showing a car 1a for a high floor and a car 1b for a middle floor of the elevator apparatus according to Embodiment 20. In the figure, reference numeral 32 denotes a car proximity detector having, for example, a bar of several meters and having a sensor at the tip, and mechanically detects that another car is approaching. The car proximity detector may be of a type in which a sensor is provided in one car and a fin extending several meters upward or downward is provided in the other car, and the fin enters the sensor to detect the fin. Further, a method of operating a limit switch as performed in a conventional pit portion may be used.

The distance between the cars can be known from the operating states of the hoisting machine controlled by the control device and the hoisting machines of other cars, but from the viewpoint of further safety, the distance in the present embodiment is A measuring device 30 and a car proximity detector 32 are provided.

Since the distance measuring device 30 has been described in the seventeenth embodiment, the car proximity detector 32 will be described here. The safety is monitored by controlling the distance between the cars, but this embodiment is for the case where the control by the control device becomes abnormal and cannot be controlled. If the output of the distance measuring device 30 becomes unreliable, the car proximity detector 32 mechanically detects that the cars are approaching abnormally.

時 When the distance between the cars approaches the dangerous distance for some reason, the emergency stop mechanism that stops the car mechanically is activated in conjunction with this proximity detection.

FIG. 27 is an explanatory diagram showing an example of the configuration of the emergency stop mechanism of the elevator apparatus, and schematically shows one rope drive system of the elevator apparatus in the YZ plane. In the figure, reference numeral 33 denotes a disk brake that operates on the hoisting machine 4, and reference numeral 34 denotes an emergency stop provided between the car 1 and the guide rail 8.

で は In this embodiment, two emergency stop mechanisms of the disc brake 33 and the emergency stop 34 are provided. When mechanically detecting that another car 1 is approaching, the disk brake 33 forcibly stops the rotation of the hoisting machine 4 and stops the car 1 in conjunction with this. The emergency stop 34 fixed to the car 1 is coupled to the guide rail 8 so as to grip the guide rail 8 and stops the movement of the car 1.

According to this embodiment, in a case where one hoistway has a plurality of cars, even if the distance between the cars approaches a dangerous distance for some reason, it is possible to stop the cars and avoid the danger. It is possible to obtain a highly safe elevator device.

In this embodiment, two emergency stop mechanisms of the disc brake 33 and the emergency stop 34 are provided, but either one may be used.

Embodiment 21 FIG.
Hereinafter, an elevator apparatus according to Embodiment 21 of the present invention will be described with reference to the drawings. 28 and 29 are side views schematically showing an elevator apparatus according to Embodiment 21. In the first embodiment, the turn-up position of the main rope 2a is arranged at a position where the entire floor of the hoistway can be moved in the rope drive system for the high floor, and a part of the entire rope-walk is moved in the other rope drive systems. The return position of the main ropes 2b, 2c is arranged at a position where the main ropes 2b, 2c can be moved. In this embodiment, the main ropes 2a, 2b, 2c are moved to a position where all the rope drive systems can move on the entire up-and-down stroke of the hoistway. The turning position is arranged.

In the zone service operation method as in the first embodiment, the moving range of the car 1 is determined, and the car 1 must be selected according to the desired floor. On the other hand, according to the configuration of this embodiment, when a passenger rides on a car, it moves independently within a range where all of the plurality of cars 1 do not come into contact with the upper and lower cars 1 according to the passenger's request. be able to.

In the first embodiment, a machine room for storing the hoist 3, the sheave 4, and the deflector wheel 5 must be provided at each position, but in this configuration, all can be stored in one machine room.

FIG. 28 shows that, when the inverted U-shaped rope drive system is projected on the YZ plane, the inverted U-shaped rope drive system is overlapped so as to cover each other in a non-contact manner in the ascending and descending directions. An example is shown in which the moving plane of a plurality of rope drive systems is configured to be substantially the same plane when the plane formed is a moving plane.

FIG. 29 shows an example in which each of the moving planes of the plurality of rope drive systems is substantially parallel to the Z-axis, and each of the moving planes is configured to be substantially orthogonal to at least one of the other moving planes. .

As described above, in both configurations, the return positions of the main ropes 2a, 2b, and 2c are arranged so that all the rope drive systems can move on the entire up-and-down stroke of the hoistway.

Embodiment 22. FIG.
Hereinafter, an elevator apparatus according to Embodiment 22 of the present invention will be described with reference to the drawings. FIG. 30 is a side view schematically showing an elevator apparatus according to a twenty-second embodiment.

In this embodiment, the entire hoisting path of one hoistway 7 is divided into a plurality of zones, for example, three zones of a high floor (FH), a middle floor (FM), and a low floor (FL), and stored in the hoistway. The moving ranges of the plurality of cars are assigned from the top of the zone in order from the one located at the top. That is, the high-floor car 1a moves in the high-floor zone (FH), the middle-floor car 1b moves in the middle-floor zone (FM), and the low-floor car 1c moves in the low-floor zone (FL).

As described above, in a zone service operation system in which only a part of the entire ascending and descending process is stopped when there is a request, and the other floors are not stopped, the elevator is located on a plurality of cars 1 accommodated in one hoistway. The upper floor of the zone divided from the car 1 is serviced.

As shown in the figure, two hoistways 7 are provided to connect the high-rise cars 1a, the middle-floor cars 1b, and the low-floor cars 1c, and connect one car to the counterweight of the other car. We use as. In addition, the hoist 3, the sheave 4, and the deflector 5 are shared for each zone. Of course, as in the conventional case, a system having one hoistway and a counterweight may be used.

(4) When the service area is completely divided and operated in each car 1 in this way, there is an effect that an elevator apparatus that is safe and has a simple configuration can be obtained without danger that the cars may approach each other abnormally.

Embodiment 23 FIG.
Embodiment 23 Hereinafter, an elevator apparatus according to Embodiment 23 of the present invention will be described with reference to the drawings. FIG. 31 is an explanatory diagram for describing a floor call button in operation of the elevator apparatus according to Embodiment 23. In this operation system, as shown in FIG. 28, the configuration of each car 1 is configured to be able to move up and down the entire stroke of the hoistway, and all the hoisting machines 3, the sheaves 4, and the deflecting wheels 5 are arranged in one machine room. It is stored in M. The operation system uses the zone service system. The high floor car 1a covers the range of the high floor (FH) of 21F to 30F, and the middle floor car 1b covers the range of the middle floor (FM) of 11F to 20F. The low-floor car 1c covers a range of low floors (FL) from 1F to 10F. The reference floor (FI) is 1F. Also, in the figure, A shows a configuration example of floor call buttons of 21F to 30F, B shows a configuration example of floor call buttons of 11F to 20F, and C shows a configuration example of floor call buttons of 2F to 10F. The number corresponding to the floor is written in □. For example, in the floor call button on the 25F, 26F is written in the square of {} for instructing to go up, and 24F in the square of {} for instructing to go down.

呼 び There are many cases where there are only up and down buttons as call buttons on each floor of the conventional elevator system. However, when a plurality of cars are operated on one hoistway as in the present invention and, for example, a zone service system is used, it is difficult to allocate the cars unless it is known which zone is to go up or down. Therefore, it is efficient to arrange the call buttons of each zone on the call buttons on each floor as shown in FIGS. 31A, 31B and 31C so that passengers can press the buttons of their own target zones. The operation of the basket can be performed.

Furthermore, if the call button is provided with a call button for the first floor (FI) which is considered to be particularly frequently used, it can be operated more efficiently.

You may be able to press this button on all floors. Further, the service zone of each car 1 may be configured to overlap at least one floor so that transfer to each zone is possible. For example, 21F may be able to stop both the middle floor car and the high floor car.

In addition, if a person on a higher floor wants to go to a lower floor or vice versa, the high-rise car can be stopped at least partially on the lower floor while the lower car is descending, or the lower car can reach the upper floor. You may be able to ascend.

In the elevator apparatus, a space for storing the car 1 may be provided on the first floor or below the standard boarding floor. If this space is provided below the hoistway 7, the structure can be simplified. In addition, if a plurality of them are provided in the middle of the hoistway 7, they can be used as emergency shelters during operation.

The number of cars 1 provided in one hoistway 7 is not limited to three, but may be two or three or more.

Further, although the hoisting machine 3 and the counterweight 6 are provided in each car 1, any one of them may be used.

In addition, although the description has been given mainly of the construction of the driving means by the hoisting machine 3, the sheave 4, and the main measure 2, a system using a linear motor as shown in FIG. The system may be used.

主 Also, the main measure 2 may not be a wire rope but may be a chain or other transmission means.

If the car 1 can be evacuated from the hoistway 7 and a mechanism that allows the lower car 1 to pass the upper car 1 can further increase the operation efficiency.

Further, in Embodiments 1 to 23, only one car 1 is provided in a place where one operation is performed, but two cars may be connected like a double deck. That is, in FIG. 1, the car can be composed of three places × 2 = 6 cars, and the transport amount is further increased. Of course, two or more decks may be used, or a part of the deck may be a double deck.

The elevator apparatus configured as in Embodiments 1 to 23 can be configured with almost no change in the components of the conventional elevator apparatus, and can transport a large number of people in a narrow elevator installation area. In addition, since different floors can be serviced by a plurality of cars, almost the same service can be provided even in the case of mass transportation. Therefore, in a building requiring a large amount of transportation power such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

Embodiment 24 FIG.
Hereinafter, an elevator apparatus according to Embodiment 24 of the present invention will be described with reference to the drawings. 32 and 33 are side views schematically showing an elevator apparatus according to Embodiment 24.

The elevator apparatus according to Embodiments 1 to 23 is called 1: 1 roping, and is a roping method in which when the car moves one time, the counterweight also moves one time. In this embodiment, as another roping method, an embodiment relating to an elevator apparatus using 2: 1 roping in which one side of a main rope is connected to a fixed end as shown in FIG. 47 will be described. In this method, the car moves by a half of the movement of the main rope 1.

FIG. 32 shows a state when the car gets into the car, and FIG. 33 shows a state when the car stops on the upper floor. In the figure, FI is a boarding floor, and FS1 and FS2 are floors higher than FI, for example, lower floor and middle floor. One end 2a of the main rope 2 is connected to a fixed portion, and the other end 2b is connected to a counterweight 6 via a sheave 4. The first car 1a is directly connected to the main rope 2. In addition, the second car 1 b is indirectly hooked to the main rope 2 via the deflecting wheel 5.

As shown in the drawing, when the sheave 4 is rotated by the hoisting machine 3 from a state in which the first car 1a is fixed to the entry floor FI, power is transmitted to the main ropes 2 by traction, and the cars 1a, 1b Rises. For example, as shown by arrow A in FIG. 33, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a moves from the boarding floor FI to the middle floor as shown by arrow B. Move to FS2. That is, while the second car 1b moves by one, the first car 1a moves by two.

In this way, by fixing one end of the main cable 2 and connecting the second car 1b via the deflecting wheel 5 to the main cable 2, the first car 1a directly connected to the main cable 2 The lifting distance by the hoisting machine 3 is different between the second car 1b.

As described above, in the present embodiment, two cars 1a and 1b can be simultaneously driven by one hoistway even though they are driven by one drive motor, and the two cars 1a and 1b are different. The floor can be serviced. For this reason, a large number of passengers can be transported by one hoistway, and the lower floor FS1 and the middle floor FS2 can each be used as a sky lobby floor of a high-rise building or the like, and used as a shuttle elevator that goes directly to and from the sky lobby floor.

Also, the components of the conventional elevator apparatus can be configured with almost no change, and a large number of personnel can be transported with a narrow elevator installation area. In addition, a single hoist can service different floors with a plurality of cars, so that the service can be performed more efficiently than a conventional double deck elevator.

In addition, if multiple hoists are used, the degree of freedom of each car is increased, and the service is further improved. Therefore, in a building requiring a large amount of transportation power, such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

For example, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a is moved from the boarding floor FI to the higher floor FS3, and the third car 1c is moved from the boarding floor FI. Move to lower floor FS0. The lower floor FS0 is a central floor from the boarding floor FI to the lower floor FS1. That is, when the first car 1a moves by one, the second car 1b moves by 、, and the third car 1c moves by ４.

In this manner, one end of the main cable 2 is fixed, the second car 1b is connected to the main cable 2 via the deflecting wheel 5, and the third car is further connected to the second car 1b via the deflecting wheel 5. When the first car 1c is connected, the first car 1a, the second car 1b, and the third car 1c directly connected to the main rope 2 have different lifting distances by the hoisting machine 3.

Embodiment 29 FIG.
Hereinafter, an elevator apparatus according to Embodiment 29 of the present invention will be described with reference to the drawings. FIG. 38 is a side view schematically showing an elevator apparatus according to Embodiment 29. The configuration of the elevator apparatus described in Embodiments 1 to 28 is a configuration in which the car rises and descends on the hoistway, and the main rope moves reciprocally. However, this embodiment has a ring-shaped main rope. Is rotated to circulate the car.

The sheave, 4c is the sheave for the lower main rope, 5a is the deflector for the upper main rope, 5b is the deflector for the middle main rope, 5c is the deflector for the lower main rope, and 7A is the basket. 1 is a rising path, 7B is a descending path on which the car 1 descends, 10a, 10b, 10c are provided on the lower deflecting wheels of the main ropes 2a, 2b, 2c, and 11a to 11h are provided on the cars 1a to 1h, respectively. , A coupling mechanism detachable from the main rope 2 and the sub rope, for example, a rope gripping change mechanism. In addition, 12a is an upper car lateral movement mechanism, 12b is a lower car lateral movement mechanism, and LA is a loop A formed by a rope drive system on a higher floor, LB is a loop B and LC formed by a rope drive system on a middle floor. This is the loop C formed by the rope drive system on the lower floor. Arrow U indicates the upward direction of the car, and arrow D indicates the downward direction of the car.

Hereinafter, the structure of the elevator apparatus according to this embodiment will be described with reference to the drawings. In the loop A (LA), the cars 1g and 1e are connected and balanced with the main rope 2a via the rope gripping mechanisms 11g and 11e. In the loop B (LB), the cars 1h and 1d are connected and balanced with the main rope 2b via the rope gripping mechanisms 11h and 11d. Further, in the loop C (LC), the cars 1a, 1c are connected to the main rope 2c via the rope gripping mechanisms 11a, 11c, and are balanced.

か The cars 1b and 1f are connected to the moving ropes of the lateral moving mechanisms 12a and 12b via the rope gripping mechanisms 11b and 11f, respectively.

Next, the operation of this embodiment will be described.
In the loop C (LC), the car 1a is raised in the U direction by the sheave 4c by the driving force of the hoisting machine 3c, and at the same time, the car 1c balanced with the car 1a is lowered in the D direction. Synchronously with this movement, the car 1h and the car 1d move in the loop B (LB), and the car 1g and the car 1e move in the loop A (LA).
During this vertical movement, the car 1b is laterally moved from the descending direction to the ascending direction by the lateral movement mechanism 12b. At the same time, the car 1f is laterally moved from the upward direction to the downward direction by the lateral movement mechanism 12a. That is, the cars 1b and 1f respectively move laterally in the direction opposite to the direction in which they have moved so far.

When the car 1a reaches the stop floor (FS1), the car 1a stops and passengers get on and off. During this time, the rope gripping mechanism 11a of the car 1a operates to grip the low-rise main rope 2c to the middle-rise main rope 2b. Similarly, the cars 1h, 1e, and 1d stop at the stop floor and change the rope to the next main rope 2.

At this time, the car 1c and the car 1g arrive at the getting-off floor (FI) and the top floor (FS3), respectively, and at the same time when the passengers get off, the rope gripping mechanisms 11c and 11g operate, and the main rope 2c and the main rope 2a. It is grasped by the moving ropes of the car lateral movement mechanisms 12b and 12a.

Ascending and descending while grasping and changing the main rope by repeatedly attaching and detaching the main rope. For this reason, many cars can be operated with a conventional load, a large amount of transportation can be obtained with a small installation area, the configuration can be made at low cost, and there is an effect that the vehicle can be operated safely.

Particularly, since the number of cars 1 connected to one main rope 2 can be reduced as compared with the conventional ring-shaped elevator apparatus shown in FIG. 48, it is possible to prevent a large load from being applied to the main rope and the hoist.

Further, in this embodiment, since the cages of the weights that are almost balanced with each other are attached to and detached from the main ropes almost in synchronism with one rope drive system, a counterweight is not required and the configuration is complicated. Can be prevented and a safe elevator system is obtained.

Further, since all the cars 1 are attached to and detached from the main cable 2 almost at the same time, the balance can be prevented from being lost, the distance between the cars 1 can be kept constant, and a safe elevator device can be obtained.

Further, in this embodiment, eight cars 1 are provided, and the number of cars is not limited to this. However, if at least twice the number of the main ropes 2 is provided, one ring-shaped rope drive is provided. A pair of cars 1 can be connected in the system. For example, when the number of passengers during the daytime is small, the number of cars may be the minimum number (the number of main ropes × 2), and when the number of passengers in the morning and evening is large, the number of cars may be increased.

Also, in this embodiment, three ring-shaped rope drive systems are provided, but the present invention is not limited to this, and any number may be used.

Further, an operation system of the elevator apparatus according to the present embodiment will be described below. In this embodiment, three ring-shaped rope drive systems are configured to provide services for each zone of a high floor (FH), a middle floor (FM), and a low floor (FL).

FIG. 39 is an explanatory diagram illustrating an example of an operation system when performing the zoning service according to the present embodiment.

The operation procedure is shown below.
t1 (from mode 1 to mode 2)
: Car A operates in express, stops at FS1, opens the door, gets off the user on the way, grabs the rope from main rope 2c to 2b, and closes the door.
: Car B moves sideways, opens the door and gets the user in, grabs the rope from the sideways rope to the main rope 2c, and closes the door.
t2 (from mode 2 to mode 3)
: Car A operates in express, stops at FS2, opens the door, gets off the user on the way, grabs the rope from main rope 2b to 2a, and closes the door.
: Car B drives expressly, stops at FS1, opens the door, gets off the user on the way, grabs the rope from main rope 2c to 2b, and closes the door.
: The car C moves sideways, opens the door to let the user get in, grabs the rope from the sideways rope to the main rope 2c, and closes the door.
t3 (from mode 3, mode 4 to mode 1)
: Car A, Car B, and Car C perform low, middle, and high floor services on each floor.
: The car D moves sideways, opens the door to let the user get in, grabs the rope from the sideways rope to the main rope 2c, and closes the door.

By operating as described above, it is possible to smoothly service many passengers.
In addition, since cars are coming one after another, the transportation capacity is greatly improved, and in buildings that require a large amount of transportation capacity such as high-rise buildings, the elevator installation area can be reduced without lowering the transportation service, and the floor of the building can be reduced. Effective use of area is possible.
Although the operation method according to the present embodiment is an operation example of the zone service method, it may be used as a shuttle elevator that stops only at a stop floor provided in the middle of a building.

In addition, many cars are not connected to one main rope as in the case of a circulation type elevator. In the above embodiment, each main rope has only two cars. Therefore, the same load as when driving with a car and a counterweight is used, and the components such as the hoist and the rope can drive the same load as the conventional one, and no new high-load component is required, and the cost is low. Can be.
