Conventionally, maintenance and inspection of elevator hoistways has been performed by climbing onto the top of the car. The way to board the car is to make a group of two people, one goes out to the hall, and the other waits by pressing the maintenance operation button inside the car so that the floor surface and the top of the car are at the same height. The person who was waiting in the hall opens the door of the hall and climbs onto the car, then presses the maintenance button on the car to operate the UP car, and aligns the floor surface with the car floor. Then, use the maintenance button on the car again to carry out DN operation until the floor surface and the car surface are at the same height. It was placed on top of the car. However, recently, in order to save labor, various studies have been conducted to allow one person to carry out maintenance and inspection of the hoistway. However, if you want to get onto the car by yourself, use the maintenance operation button inside the car to stop the car by aligning the floor surface with the car floor, then go up the stairs to the upper floor and go to the upper hall. The driver must open the door and climb onto the car, but if the floor pitch is high, there will be a difference in level between the floor and the top of the car, making it extremely dangerous to get into the car. Currently, even work that can be done by one person is performed by two people for safety reasons.

In order to achieve the above object, the present invention provides for a maintenance worker to lower the car from a state where the car is stopped on a predetermined floor using a lowering command means, and to lower the upper surface of the car and the floor of the specific floor. When the car is lowered until the values substantially match, the position detecting device detects this, and upon this detection, the stop command means outputs a command to stop the lowering of the car.

込み保守作業を開始する。 Now, a description will be given of an operation in which a maintenance worker climbs onto the car in order to perform maintenance in the hoistway. First, in the above configuration, in order to get onto the car, the maintenance worker stops the upper floor floor surface A and the car floor surface B together, and switches the high-speed/low-speed changeover switch 8 to the low-speed side to relay the high-speed 9
Turn off, and turn on low speed relay 10. Next, the maintenance operation preparation switch 12 is turned on, the boarding button 16 is pressed, and the driver goes to the upper floor floor A and waits. When the boarding button 16 is pressed, the boarding relay 13 is turned on. Here, the maintenance operation preparation switch 12 is structured so that it continues to be turned on even if the user releases his/her hand, and when the boarding button 6 is released, it returns to its original state. The boarding relay 13 is self-maintained by the boarding relay's a contact 13a1 . Next, when the boarding relay 13 turns on,
The DN time relay 15 starts counting the time by the A contact 13a2 of the boarding relay, and when a certain period of time has elapsed, the time is up and the DN time relay 15 is turned ON. DN time relay 15 is ON
Then, a DN command is given to the elevator and the elevator starts running at low speed. When the elevator continues its DN travel and reaches the dotted line position in Figure 1, the boarding position detection switch 5 is actuated by the boarding position detection switch operating cam 6, and the boarding position detection relay 14 is turned ON. When the boarding position detection relay 14 is turned on, the boarding relay 13 is turned off by the b contact 14b of the boarding position detection relay, and the boarding relay's a contact 13 is turned off.
When a2 is opened, the DN time relay 15 is turned off. The DN given to the elevator for this purpose
The command is gone and the elevator is on the upper floor, floor A.
The car stops when the upper surface C of the car and the car are aligned (as shown by the dotted line in Figure 1). Next, the maintenance worker who was waiting on the floor A of the upper floor unlocks the door lock of the upper floor entrance 1, opens the entrance door, operates the operation selector switch 7 above the car downwards, and switches the car to the upper floor. It is possible to drive on top. When switching to on-car operation, the in-car low-speed relay 10 is turned off, and the on-car low-speed relay 11 is turned on. When the on-car low-speed relay 11 is turned ON, the maintenance operation circuit of the elevator is disabled by the b contact 11b of the on-car low-speed relay, and the maintenance worker gets on top of the car and starts maintenance work.
以上が本発明の一実施例の説明で、この実施例
によれば、保守員一人でも、安全に乗りかご上に
乗り込むことができる。 The above is a description of one embodiment of the present invention, and according to this embodiment, even a single maintenance worker can safely board the car.

を達成し得る。 In this example, the maintenance operation was performed inside the car, but the same purpose could be achieved by providing an operation button or the like anywhere on the upper floor A to perform a series of operations. It can be achieved. Further, although the boarding position is detected by the boarding position detection switch 5 and the boarding position detection switch operating cam 6, it is also possible to store the boarding position in the microcomputer of the elevator operation control section and detect the boarding position. Similar objectives can be achieved.
