DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope type elevator, and more particularly, to a hoistway for performing maintenance, inspection and repair of a hoist and a control unit, and rescue of passengers in an emergency. The present invention relates to a rope-type elevator that can be performed from outside of a hoistway without any problem and has improved work safety.

[0002]

2. Description of the Related Art Conventionally, a rope type elevator without an elevator machine room is used for checking and repairing a hoisting machine and a control unit installed on a hoistway which forms a space for a car to go up and down. In addition, the operator has to enter the hoistway, and the danger to the above-mentioned operation is great.

For example, in the case of a bottom drive type in which a hoisting machine or the like is installed at the bottom of a hoistway to drive an elevator, an operator operates a bottom pit portion in the hoistway.
Since the worker works in a situation where a car is present above the head, there is a risk that the worker may drop an object from above the head. In addition, since the worker works while feeling the danger, a work error or the like is likely to occur. Furthermore, when the car stops at the lowest floor and becomes inoperable, it is not possible to get down to the pit from the normal elevator entrance on the lowest floor. Must go out to the space in the hoistway, and pass between the car and the hoistway wall to reach the pit portion, which requires a large amount of labor for work, and it is difficult to carry in and carry out the equipment. In addition, it is conceivable to perform repairs etc. by separating from the outside of the hoistway without entering the hoistway, but there are limits to the operations that can be performed compared to the case of working directly, and it takes a long time to work. It is not realistic because it requires cost and equipment cost.

[0004] In the case of an overhead drive type in which a hoisting machine or the like is installed at the top of a hoistway to drive an elevator, an operator must ascend to the top of the hoistway. For this reason, ladders and other equipment for climbing to the top must be brought into the hoistway, and the ladders and other equipment required for repairs and the like must be lifted. It takes effort.
Further, the work is performed in a place where the scaffold is unstable, so that the workability is poor. Further, there is a possibility that the worker may fall, and a serious accident that may be fatal may occur.

That is, the hoisting machine 4 and the control unit 5 are installed at positions operable from the work floor surface 15 through the opening 10. Further, since the hoisting machine 4 and the control unit 5 are arranged at positions close to each other, the operator can perform repair and inspection of the hoisting machine 4 and the control unit 5 without moving. Therefore, work efficiency such as repair and inspection of the hoisting machine 4 and the control unit 5 is good.

In the rope type elevator 1, since the opening 10 is present and the hoisting machine 4 and the control unit 5 are installed at the positions described above, an operator enters the inside of the hoistway 3. The hoisting machine 4 and the control unit 5 can be repaired without the need.

That is, in the conventional rope type elevator, the hoisting machine and the like are housed in the pit or the overhead, and do not have a structure directly from the outside of the hoistway to the inside of the pit or the overhead. It is not possible to repair the hoisting machine or the like unless an operator enters the overhead section. However, the rope type elevator of the present invention has an opening in the hoistway wall, and the hoisting machine or the like has the opening. , It is possible for a worker to repair a hoist and the like from the floor outside the hoistway without entering the hoistway.

In the rope type elevator according to the present invention, the installation positions of the hoist and the control unit are limited to the positions shown in FIGS. 1 and 2 as long as they can be operated from the work floor through the opening. For example, it may be installed at any place on the hoistway wall surface that forms the concave portion, or may be installed on the hoistway wall surface portion other than the hoistway wall surface that forms the concave portion. Alternatively, a mounting support may be separately provided in the hoistway, and the hoist and the control unit may be mounted thereon.

In the rope type elevator according to the present invention,

Accordingly, dust or water does not enter the hoistway from the outside of the hoistway 3 through the opening 10, and the hoisting machine 4 and the control unit 5 cause a failure due to the dust or water or the like. There is no such thing. Further, there is no danger that a child or the like accidentally enters the hoistway 3 from the opening 10.

When the hoisting machine 4 and the control unit 5 of the rope type elevator 1 are repaired or inspected, the lock on the inspection door 11 is opened, and the inspection door 11 is opened.
With this operation, the opening 10 is opened, and the external space of the hoistway 3 and the internal space of the hoistway 3 communicate with each other through the opening 10. When the inspection door 11 is opened, the signal is transmitted to the control unit 5, and the operation of the control unit 5 disables the automatic operation of the rope type elevator 1. Therefore, safety when the inspection opening / closing door 11 is opened is ensured.

The hoisting machine 4 and the control unit 5 are installed in the recess 8 provided in the hoistway 3 near the wall surface where the opening 10 is provided, and the size and position of the opening 10 are as follows. The hoisting machine 4 and the control unit 5 are designed so that the whole of the hoisting machine 4 and the control unit 5 can be seen when the hoisting machine 4 and the control unit 5 are viewed horizontally from the work floor surface 15 through the opening 10. That is, the hoisting machine 4 and the control unit 5 are installed at positions operable from the work floor surface 15 through the opening 10. Therefore,
The worker can repair or inspect the hoisting machine 4 and the control unit 5 from the work floor 15 outside the hoistway 3 through the opening 10 without entering the hoistway 3. In addition, since the work place is not a special space such as the pit 6 or the overhead 7 in the hoistway, but the work floor 15 which is a normal floor, not only safety in work is high, but also
Workability is improved.

When the work such as repair or inspection is completed, the inspection door 11 is closed and locked. In addition, a signal corresponding to the closing of the inspection door 11 is transmitted to the control unit 5, and the operation of the control unit 5 enables the rope-type elevator 1 to automatically operate.
