Description

[Detailed description of the invention] 3. Detailed description of the invention (Industrial application field) The present invention relates to a maintenance operation device for a police officer and an elevator.

(Prior art) -ffK, maintenance inspection 41 of the elevator hoistway is carried out by a maintenance worker riding on the top surface of the car. Traditionally, two people worked together to get on board using the following method. In other words, one person waits at the platform, another person enters the car, and
Operate the maintenance operation button inside the car to lower the car until the landing floor and the top of the car are at the same height. Next, the person waiting at the platform opens the platform door and climbs onto the top of the car, then presses the maintenance button on the top of the car to raise the car, aligning the platform floor with the car floor. The people in the car should come out to the platform.

Then, by pressing the dedicated maintenance button on the top of the car, the car was lowered again until the platform floor and the top of the car were at the same height, and the person who had been at platform 5 got into the top of the car.

On the other hand, when disembarking from the top of the car, operate the maintenance button on the top of the car, stop it at a position where the platform floor and top of the car are at the same height, and each person gets off to the platform and waits. Next, the maintenance button is pressed to raise the car and stop it at a position where the first platform floor and the car floor are at the same height, and the person waiting at the platform gets into the car.

Thereafter, the person on the barge drives the car down using the maintenance button, stops again at a position where the landing floor and the top of the car are at the same height, and descends from the top of the car to the landing. Finally, the person inside the car operates the maintenance operation button inside the car, stops the car at the position where the landing surface and the car floor are aligned, exits from inside the car to the landing, and completes the work. It was.

(Problems to be Solved by the Invention) Recently, with the trend toward labor saving, various studies have been made to allow one person to perform maintenance and inspection work on devices and equipment installed in the hoistway. . However, in order for one person to board the car, use the maintenance button inside the car to stop the car by aligning the platform floor with the car floor. Then, you have to go up the stairs to the floor one floor above, open the landing door on that floor, and board the car. However, if the distance between each floor is large, a thick step will occur between the floor of the landing area and the top of the car, making it extremely dangerous to board the car. Therefore, for safety reasons, two people must work together.

An object of the present invention is to provide a device that allows even one person to safely get on and off the car when getting on or getting off the car.

(Another means to solve the problem) A feature of the present invention is that a maintenance operation operation means operated by maintenance personnel is provided on a call operation panel provided at the entrance/exit of a certain floor of the factory.
On the other hand, the car driving circuit includes a device that is operated by a command from the operating means to drive the car to a position where the top surface of the car and the landing floor are aligned; In view of the current situation, the system is equipped with a device that moves the elevator car to a position where the floor surface of the car and the floor surface of the landing area are aligned.

(Function) The car can be raised and lowered using the operating means provided on the call operation panel. This allows maintenance personnel to easily align the top of the car and the floor of the landing, or the floor of the car and the floor of the landing.
Even humans can perform maintenance and inspections on the car.

Furthermore, since the operation means are incorporated into the call operation panel, installation can be done at low construction costs.

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

In Figures 1 and 2, 1 is the upper floor entrance/exit, 2 is the lower floor entrance/exit, 3 is the robe for the hanging car, 4 is the car, 5 is the boarding position detection switch, and 6 is the operating cam of the switch 5. , 7 is a return position detection switch.

8 (operation cam of the Eswitch 7, A (floor surface of the landing area on the construction floor, B) the floor surface of the kX car, C the top surface of the car car, 9 is the call operation panel installed at the entrance/exit of the specified floor, and this operation m9 A maintenance operation operating element (hereinafter referred to as "operating element") 9a is provided to be operated by a maintenance worker. In Fig. 3, a high/low speed changeover switch, 111'!, 111'! [Quick relay.

12 is a low speed relay operated by the high/low speed changeover switch 1o. When this high-speed relay 11 is energized, it is t'zXV-regular operation, and when the low-speed relay 12 is energized, it is maintenance operation. 13 Police unit operating body 9a
A lowering relay 14 is energized when the operating body 9a is activated to the lowering side and is used to lower the car 4 at low speed. 15 is a lowering stop relay that is energized when the boarding position detection switch 5 is turned on.
Reference numeral 16 denotes a lift stop relay that is energized when the return position detection switch 7 is turned on.

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 for the maintenance worker to get on the car, the upper floor floor surface A and the car floor surface B are brought together and stopped.
Switch the high/low speed selector switch 10 to the low speed side. At this time,
The low speed relay 12 is energized and the contact 12a is turned ON. In this state, go out to the boarding area and operate the operating body 9a to the descending side. Then, the lowering relay 13 is energized and the car starts lowering. During this descending operation, when the boarding position detection switch 5 is turned on by the operating cam 6,
The descending stop relay 15 is energized.

Contact 15b of the descending stop relay turns OFF. As a result, the lowering relay 13 is set to 0FFL, and the car stops at a position where the upper floor surface A and the upper surface C of the car match. Then, the maintenance worker gets on top of the car and performs maintenance inspection work inside the hoistway.

On the other hand, when the maintenance staff completes the first maintenance inspection work inside the hoistway,
As shown in Fig. 2, align the upper floor A and the top surface C of the car, and get off at the upper floor AK. After that, the operating body 9
Activate a'4 to the upward side.

Then, the lifting relay 14 is energized and the 1-car car starts to be lifted. During this upward operation, when the return position is reached, the operating cam 8 turns the return position detection switch 7 ON, the upward stop relay 16 is energized, and the b contact 16b of the upward stop relay 16 is turned OFF'. As a result, the lift relay 14 reaches 0FFL, and the car stops at a position where the upper floor surface A and the car floor surface B match. The maintenance worker then gets into the car and switches the high/low speed selector switch 10 to the high speed side. Now the low speed relay 12 is 0
FFL, high speed relay 11 is ONL.

Normal operation of the elevator is possible.

In the embodiment described above, the boarding position is detected by the position detection switch 5 and the operating cam 6, and the return position is detected by the position detection switch 7 and the operating cam 8. The same objective could be achieved by having the microcomputer store the boarding position and the return position and detecting the position.

(Effects of the Invention) According to the present invention, it is possible to align the car, get on top of the car, or get off from the car by operating at a predetermined floor entrance/exit. Therefore, maintenance and inspection work on the car can be easily and safely performed by one person.
