Abstract

PURPOSE:To prevent pendulum motion pitching of a carrier, following acceleration/ deceleration, from being easily generated while widening an area of a secondary side conductor part by exciting a linear electromagnetic actuator to induce an eddy current in the secondary side conductor part, and generating a moving magnetic field to give acceleration/deceleration force to a bottom surface of the carrier. CONSTITUTION:When a carrier 1 approaches each station A according to driving a rope B rotated, guide rollers are gradually pressed down to start a rope gripper 1a opened, and in a position where the rope gripper 1a is placed in an arrival end of a forwarding track C, the rope gripper 1a, while releasing the rope B, moves running rollers 1b to run on a transfer rail. According to the above, a secondary side reaction plate 2 in a bottom surface of the carrier 1 passes successively between linear electromagnetic actuators 3 on a floor surface of the station A. The secondary side reaction plate 2 is given antipropulsive force by mutual action between a moving electromagnetic field and an eddy current to smoothly decelerate the bottom surface of the carrier 1. An upper surface of the rope gripper 1a is successively brought into contact with each tire 4 to smoothly decelerate an upper end of the carrier 1 at an equal speed to the above-mentioned deceleration.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a system for suspending equipment from a cable that circulates between the terminals at both ends via a cable gripping machine that can be gripped and can be freely roiled. A deceleration section is provided to decelerate and transfer the equipment after the cable has been separated, and a transport rail is provided from the arrival side to the departure side of each station, where the equipment is separated from the cable, looped around, and reconnected to the cable. The present invention relates to a speed adjustment device for cableway equipment, which includes:

<Prior Art> Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 61-222858, a speed regulating device for cableway equipment of this kind has been used, for example, in which the arrival side and the departure side of a forwarding track are in contact with the upper surface of the rope gripping machine of the equipment. By arranging a large number of tires to be released, each tire is driven to rotate at a predetermined speed by a drive mechanism, and the rope gripping machine, which has been separated from the cable and entered the sending rail, is brought into contact with each tire in sequence.
The running speed of the equipment is gradually reduced to allow passengers to get on and off, and then the running speed of the equipment is accelerated by sequentially contacting each tire with a rope grasper heading towards the starting end of the forwarding track. There is one that connects the equipment to the rope after determining the speed and road distance.

Also, JP-A-6.4-36556, JP-A-64-
As disclosed in Japanese Patent Publication No. 36557 and Japanese Patent Application Laid-Open No. 64-36560, a secondary conductor made of a non-magnetic good conductor is attached to the top surface of the rope gripping machine, and a linear electromagnetic An actuator is arranged along the forwarding rail, and this linear electromagnetic actuator is excited to induce an eddy current in the secondary conductor part and generate a moving magnetic field, thereby applying acceleration/deceleration force to the rope grasping machine. be.

<Problems to be Solved by the Invention> However, in the former case, such a conventional speed adjustment device for cableway equipment requires a drive mechanism that rotates a large number of tires at a predetermined speed. The structure is complicated due to the large number of parts, and maintenance work for each tire and pressing each tire to the rope gripping machine not only requires work such as adjusting the force and adjusting the drive mechanism, but also makes it difficult to maintain the rope gripping machine. Noise is generated by the contact between the machine and each tire and the drive mechanism, and in addition, as the equipment has become larger in recent years, the weight has increased, so the number of tires has to be increased, and the feed rail has become larger. There is a problem.

In the latter case, the secondary conductor is provided on the top surface of the rope gripping machine, so there are restrictions on the external dimensions of the secondary conductor, making it impossible to increase its area to obtain the desired deceleration or acceleration force. However, there is a problem in that it is not possible to cope with the increase in the size of equipment.

Furthermore, in the latter case, since the installation position of the secondary conductor that is accelerated or decelerated is far from the center of gravity of the device, pendulum-like pitching of the device is likely to occur as the secondary conductor accelerates or decelerates. There is also the problem of poor ride comfort.

SUMMARY OF THE INVENTION In view of the conventional circumstances, it is an object of the present invention to increase the area of the secondary conductor while making it difficult for a device to suffer from pendulum-like pitching due to acceleration or deceleration.

Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to arrange linear electromagnetic actuators along the floor of the stop in the deceleration section and the acceleration section. A secondary conductor made of a non-magnetic good conductor is attached to the bottom of the device facing away from the linear electromagnetic actuator, and the linear electromagnetic actuator is excited to induce an eddy current in the secondary conductor to generate a moving magnetic field. The device is characterized by applying acceleration/deceleration force to the bottom of the device.

When a plurality of tires are provided in the deceleration section and the acceleration section so as to be rotatably driven at a predetermined speed, the moving speed of the rope gripping machine is accelerated or decelerated by contact with these tires. It is preferable to synchronize the moving speed of the bottom surface of the device, which is accelerated or decelerated by the linear electromagnetic actuator and the secondary conductor section.

<Function> According to the above-mentioned technical means, the present invention is capable of increasing the area of the secondary conductor to the maximum area of the device by attaching the secondary conductor to the bottom of the device. The device can be expanded in proportion to its size, and the installation position of the secondary conductor portion, which is adjusted or subtracted, approaches the center of gravity of the device.

Furthermore, by matching the moving speeds of the accelerated and decelerated rope grasping machine and the bottom of the device, the device does not pendulum move in the traveling direction due to acceleration and deceleration.

<Example> Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in FIGS. 1 to 3, a substantially U-shaped feed rail C is horizontally arranged around the outer periphery of the pulley B of each station A, and the cables circulate between the pulleys 81. A reduction section and a sending rail C arranged from B to the arrival side of this sending rail C.
The acceleration section E, which is arranged from the departure side towards the cable line B, is attached to the bottom of the linear electromagnetic actuator 3... and the equipment 1, which are arranged along the 80 on the floor of the stop A, respectively. It is composed of a secondary conductor section 2 and a large number of tires 4 that come into contact with and separate from the upper surface of the rope gripping machine 1a of the equipment 1.

The equipment 1 is a gondola, a lift, etc. shown in the figure, and has at its upper end a rope gripping machine 1a and a traveling roller 1b that engages with the transfer rail C□ of the forwarding rail C so as to be able to swing up and down, respectively, and transport the rope to the rope gripping machine 1a. A guide roller lc that engages with the guide rail C2 of the rail C is provided in series, and when the guide roller lc is pushed up, it closes and grips the cable B, and in contrast, the guide roller lc is pushed down. The rope B is opened by
configured to roam.

Furthermore, the bottom surface of the device 1 is formed horizontally, and the secondary conductor part 2 made of a non-magnetic good conductor such as aluminum or copper, more specifically the secondary reaction plate, is formed in the longitudinal direction in the illustrated example. It is attached by welding or bolting so that the effective surface 2a faces in the direction of movement of the device 1 and in the left and right horizontal directions perpendicular to the direction of movement, and both effective surfaces 2a are arranged vertically. .

On the other hand, on the floor A A plurality of linear electromagnetic actuators 3 are arranged at equal intervals from each other at a corresponding distance from the secondary reaction plate 2 on the bottom surface of the device 1.

Each linear electromagnetic actuator 3 is connected to an inverter control device (
(not shown), and by supplying current from the inverter control device, a moving magnetic field of an amount equivalent to the amount of supplied current is generated, and the inverter control device moves from the arrival end toward the intermediate corner. The device causes the moving speed of the moving magnetic field to gradually slow down, and the inverter control device causes the moving speed of the moving magnetic field to gradually increase from a part of the middle corner toward the eighth starting point.

In the illustrated example, each linear electromagnetic actuator 3 is connected to the effective surface 2a of the secondary reaction plate 2.

The secondary reaction plate 2 is sandwiched between the left and right linear electromagnetic actuators 3, 3 by arranging them in pairs in the left and right horizontal directions orthogonal to the traveling direction of the device 1, facing the left and right linear electromagnetic actuators 2a.

In this embodiment, the distance between each linear electromagnetic actuator 3 and the effective surface 2a of the secondary reaction plate 2 is 5 to 1.
It is maintained at about 0+++m.

In addition, a large number of tires 4 are disposed on the arrival side and the departure side of the sending rail C, and each tire 4 is driven to rotate at a predetermined speed by a drive mechanism.
The moving speed of the rope gripping machine 1a, which is accelerated or decelerated by contact with these tires 4, and the linear electromagnetic actuator 3
. . . and the moving speed of the bottom surface of the device 1, which is accelerated or decelerated by the secondary reaction plate 2, are synchronized.

Furthermore, a transfer means C3 such as a chain conveyor for transferring the equipment 1 toward the departure side is disposed at an intermediate corner portion of the sending rail C.

Next, the operation of such a speed adjusting device for cableway equipment will be explained.

First, when the equipment 1 approaches each stop A as the rope B is rotated, the guide roller 1c is gradually pushed down and the rope gripping machine 13 begins to open, and when the rope has entered the arrival end of the forwarding rail C. While the rope gripping machine 1a roams the rope B, the traveling roller 1b travels on the transfer rail C.

Along with this, the secondary side of the bottom of equipment 1 is closed.

The plate 2 sequentially passes between each linear electromagnetic actuator 3, 3... on the floor surface A1 of the stop A, and the reaction plate is secondary to the moving magnetic field generated in each linear electromagnetic actuator 3, 3... An eddy current is generated in 2, and the interaction between these moving magnetic fields and the eddy current gives a counterpropulsive force to the secondary reaction plate 2, smoothly decelerating the bottom of the equipment 1, and at the same time decelerating the rope gripping machine 1a. The upper surface sequentially contacts each tire 4..., and the upper end of the device 1 is smoothly decelerated at the same speed as the deceleration by the linear electromagnetic actuator 3... and the secondary reaction plate 2.

In the case of this example, the device 1 speed when connecting cable B is 4 to 5 m.
/s to a part of the middle corner: 01~0.5m/
It is set to decelerate to about s.

Thereafter, the device 1 that has reached the intermediate corner is transferred toward the departure side by a transfer means C3 such as a chain conveyor, and the device 1
When the guide roller IC reaches an appropriate position, the guide roller IC is gradually pushed up and begins to close the rope gripping machine 1a, and the secondary reaction plate 2 on the bottom of the equipment 1 is placed on the first As it reaches between the linear electromagnetic actuators 3, 3, the upper surface of the rope gripping device 1a comes into contact with the first tire 4.

Along with this, a propulsive force is applied to the secondary reaction plate 2 by the interaction between the lowest speed moving magnetic field generated in the first linear electromagnetic actuator 3.3 and the eddy current generated by this moving magnetic field, and the bottom surface of the device 1 is transport,
Each time it passes through the gradually faster moving magnetic field generated by each of the subsequent linear electromagnetic actuators 3.3..., a propulsive force is applied to the secondary reaction plate 2, and the bottom of the device 1 is clearly accelerated. The upper surface of the rope gripping machine 1a contacts each tire 4 sequentially, and the upper end of the device 1 is smoothly accelerated at the same speed as the acceleration by the linear electromagnetic actuator 3 and the secondary reaction plate 2. .

After that, this secondary reaction plate 2 is attached to the stop A.
The last linear electromagnetic actuator 3 arranged at the starting end of
．． By the time the device 1 passes between 3 and 3, the traveling speed of the device 1 is accelerated to the speed of the cable B and the road, etc., the guide roller 1c is completely pushed up, and the rope gripping machine 1a grips the cable B.

Therefore, in the ones in Figures 1 to 3, a linear electromagnetic actuator 3 on the floor A□ of the stop A and a secondary reaction plate 2 on the bottom of the equipment 1 are added to the existing tire-driven type. Only by this, deceleration force and acceleration force corresponding to the enlargement of the device 1 can be obtained.

Next, what is shown in FIGS. 4 to 6 is a modification of the arrangement of the linear electromagnetic actuator 3... and the secondary reaction plate 2, and this one has the secondary reaction plate 2 on the bottom of the device 1. The actuator is mounted so that its effective surface 2a faces downward, and a large number of linear electromagnetic actuators 3 are disposed along the transport rail C on the floor surface A4 of the parking area A, facing away from the actuator.

Next, what is shown in FIGS. 7 and 8 is another embodiment of the present invention.

The one in Figure 7 is the one in Figures 1 to 3 mentioned above and the one in Figure 4.
A secondary reaction plate 2 is attached to the bottom of the equipment 1 in the same way as those shown in FIGS.
A large number of rope gripping machines 1a are arranged along the sending rail C, and
The secondary reaction plate 5 is placed on the upper surface of the effective surface 5.
a is mounted so that it faces upward, and a large number of linear electromagnetic actuators 6 are arranged facing away from the actuator along the feed rail C, and the secondary reaction plate 5 and the linear electromagnetic actuator on the upper surface of the rope gripping machine 1a are The moving speed of the rope gripping machine 1a is accelerated or decelerated by the actuator 6, and the equipment is accelerated or decelerated by the secondary reaction plate 2 on the bottom of the device 1 and the linear electromagnetic actuator 3 on the floor A1 of the stop A. The moving speed of the bottom surface is synchronized.

Therefore, in the devices shown in FIGS. 1 to 3, the devices shown in FIGS. 4 to 6, and the device shown in FIG. 7, the device 1 does not oscillate in the traveling direction at all with acceleration and deceleration.

In addition, in the case shown in Fig. 8, a secondary reaction plate 2 is attached to the bottom of the device 1, and the secondary reaction plate 2 is placed opposite to and spaced apart from the device 1, similar to the cases shown in Figs. 1 to 3 and Figs. 4 to 6. This is simply a large number of linear electromagnetic actuators 3 arranged on the floor A4 of the stop A along the transport rail C.

Therefore, although the device shown in FIG. 8 may cause the device 1 to vibrate to some extent in the direction of travel as it accelerates or decelerates, it has the advantage that the overall structure of the device can be simplified and costs can be reduced.

<Effect of the invention> Since the present invention has the above configuration, it has the following advantages.

■ By attaching the secondary conductor to the bottom of the device,
The area of the secondary conductor is maximum and can be expanded to the bottom area of the device, allowing it to be expanded in proportion to the size of the device.The installation position of the secondary conductor and the center of gravity of the device can be adjusted. , which approaches each other, it is possible to increase the area of the secondary conductor while making it difficult for the device to suffer from pendulum-like pitching due to acceleration and deceleration.

Therefore, compared to the conventional system in which a large number of tires are each driven to rotate at a predetermined speed, the number of parts is reduced and the structure is simplified, and once set, subsequent maintenance inspection work and adjustment work are unnecessary. It is maintenance-free, and since there is no mechanical transmission, there is no noise, and compared to conventional models that have a secondary conductor on the top of the rope gripping machine, the desired deceleration and acceleration force can be obtained, and the equipment is large. It is possible to cope with the change in size without increasing the size of the feed rail, and the riding comfort is also improved.

■ By matching the moving speeds of the accelerated and decelerated rope gripping machine and the bottom of the equipment, the equipment does not oscillate in the direction of travel due to acceleration and deceleration, which completely prevents pendulum pitching of the equipment and improves riding comfort. further improves.

Furthermore, by adding linear electromagnetic actuators on the floor of the parking lot and secondary conductors on the bottom of the equipment to the existing tire-driven type, it is possible to accommodate larger equipment and improve riding comfort at low cost.
