Abstract

PURPOSE:To make maintenance service personnel easy to transfer to both the upper and inner parts of a cage by installing a means which lights each pilot lamp in the top and inside of the cage when the cage floor and the top face are accorded with a hall floor. CONSTITUTION:When two service men transfer to the inside of a cage C and arrive at the third floor, by way of example, one person gets down to a hall 3H, and another service man in the cage pushes a descending maintenance operating button DB1 so that the cage is descended at low speed. When a top face of the cage C and a hall floor 3H are accorded with each other, a pilot lamp L2 in the cage is lighted, and when unhanding the button DB1, the cage C is stopped. Therefore the service man in the hall 3H opens a door of this hall 3H and is able to transfer onto the cage C so easily. When the service man on the cage C gets into the cage C, he transfers to the hall 3H, and an ascending operation button UB1 is pushed by another service man in the cage C so that the cage C is lifted up. When a cage floor accords with the hall floor 3H, the pilot lamp L1 is lighted and the button UB1 is unhanded, whereby the cage C comes to a stop, thus the service man can get into the cage C easily.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator maintenance operation device.

[Conventional technology]

Generally, maintenance and inspection of an elevator hoistway is performed by climbing onto the top of the car. In other words, in a group of two people, one person waits in the hall, and the other person operates the maintenance operation button inside the car until the top of the car is at the same height as the floor surface. At this point, the hall maintenance staff opens the hall door and climbs onto the top of the car, then presses the maintenance button on the car to raise the car, aligns the floor surface with the car floor, and performs maintenance inside the car. After letting the staff out to the hall, the car is lowered again using the maintenance button on the car until the top of the car is at the same level as the floor surface, and the maintenance staff who had been out in the hall is allowed to get onto the top of the car. Ta.

On the other hand, when finishing the maintenance inspection work, the car stops at a place where the floor surface and the top surface of the car are at the same height, and one of the maintenance personnel is made to go down to the hall and wait. Next, the maintenance worker on the car raises the car using the maintenance button, stops it when the floor surface of the car matches the floor surface of the car, and places the other maintenance worker, who was waiting in the hall, inside the car. . Thereafter, the maintenance person on the car starts the downward operation, stops again with the floor surface and the top of the car at the same height, and descends from the top of the car into the hall. After this, the maintenance worker inside the car stopped the car by aligning the floor surface with the car floor surface using the maintenance operation button inside the car, and got off from inside the car to work.

Note that this type of elevator maintenance and operation device is discussed in, for example, Japanese Patent Laid-Open No. 62-93192.

[Problem 1llII to be solved by the invention] In the above-mentioned conventional device, for example, when a maintenance worker climbs onto the car, the maintenance worker inside the car must Based on my intuition, I drove the specified distance and stopped the car. For this reason, if the hall maintenance staff cannot open the hall door and get onto the car, the hall maintenance staff will loudly instruct the maintenance staff inside the car how far to drive, close the door, and run the car again. There was a problem in that the process was repeated until the car stopped at a position where the hall maintenance worker could get into the car.

A similar problem also occurs when a maintenance person on the car gets into the car or when a maintenance person inside the car goes out into the hall.

In view of the above-mentioned drawbacks, an object of the present invention is to provide an elevator that allows maintenance personnel to easily climb onto or into the car when two maintenance personnel perform maintenance work on the car. Our goal is to provide maintenance and operation equipment.

[Means to solve the problem]

The above purpose is to provide a first detection means for detecting that the car floor and the floor of the hall match, a second detection means for detecting that the top surface of the car and the spherical surface of the hall match, and and a third indicator light on the top surface of the car, and when the car runs and the first detection means is activated, the first and third indicator lights are turned on. This is achieved by providing a lighting means for lighting the second indicator light when the second detection means is activated.

[Effect]

According to the present invention, two maintenance workers first get on the car and arrive at, for example, the third floor, and one of the maintenance workers goes down to the hall. The maintenance person inside the car switches to maintenance operation and presses the lower operation button to lower the car.When the car approaches the second floor and the top of the car matches the third floor hall floor, the second indicator light inside the car lights up. lights up. Then, the maintenance person inside the car stops the car by releasing the button.

Hall maintenance personnel can open the door on the third floor and climb onto the car.

Furthermore, in order to get into the car, the hall maintenance worker opens the door on the third floor from above the car, goes down to the hall on the third floor, and closes the door. When the maintenance person inside the car operates the operation button for raising, the car rises, and when the floor of the car matches the floor surface, the first indicator light lights up. By releasing the button, the car stops and the hall maintenance personnel can easily get into the car.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. It is assumed that the cars are in service on the 1st to 5th floors.

FIG. 1 is an electrical wiring diagram showing an embodiment of the elevator maintenance and operation apparatus of the present invention, and FIG. 2 is an explanatory diagram.

In FIG. 1, P and N are DC power supply terminals, H is a relay for high-speed operation, L is a relay for low-speed operation La is its normally open contact, and relays H and L are switched by a switch SW.

UBa, UBa, normally open contacts of maintenance buttons UB1 and UB2 for lifting provided inside car C and on top of car C, U
is a relay that is energized when the maintenance button UB2 is operated, and when this relay is energized, the car C is operated upward at a low speed by a control device (not shown). Similarly, DBa,,D
Baz is the normally open contact of the lowering maintenance buttons DB, DB, provided inside the car C and on the top of the car C, and D is the maintenance button DB.
,, When this relay is energized when DB2 is operated, the car C moves downward at a low speed. F is a finger (not shown) of a floor selector, 20S to 508 are segments of the floor selector, and 2LS to 5LS contact finger F when the floor surface of car C coincides with the floor surface of floors 2 to 5. At the same time, the indicator light L2 inside the car C and the indicator light L3 on the upper part of the car C light up. Similarly, in 2oS~508, when the top of the car C matches the floor surface of the 2nd~5th floor, the finger F
At the same time, the indicator light L in the car C lights up.

In Figure 2, 2H13H is the hall on the 2nd and 3rd floors, 2D and 3D are the doors on the 2nd and 3rd floors, C is the car, R is the rope that lifts the car C, and inside C is the maintenance button UB for lifting. , a descending maintenance button DB, indicator lights L□, L2 are provided, and on the other hand, an ascending maintenance button UB2, a descending maintenance button DB2, and an indicator light L3 are provided at the top of the car C.

Next, the operation of this embodiment will be explained.

Now, two maintenance workers (referred to as A and B) board car C from the first floor and arrive at the third floor at high speed. The position of car C at this time is assumed to be PSl. Therefore, the switch SW is switched to the relay L side. Maintenance worker A goes to hall 3H. Maintenance worker B in car C keeps pressing maintenance button DB. P-L a-D
A circuit of B a, -D-N is formed, and relay D is energized, so that car C descends at a low speed. Finger F
When the car C contacts the segment 30S, a circuit of P-La-F-30S -L, -H is formed at the position of PSl in the car C, and the indicator lamp L in the car C lights up. Then, maintenance worker B releases the maintenance button DB□, and car C stops. At this time, since the top of the car C is flush with the floor of the hall 3H, the maintenance worker A can easily get into the top of the car C by opening the door 3D.

Next, when the maintenance worker A continues to press the maintenance button UB2, the car C rises and contacts the segment 3LS of the finger F, and the indicator light L3 lights up, so the maintenance worker A releases the maintenance button UB2.

Maintenance worker B goes to hall 3H.

Next, maintenance worker A keeps pressing the maintenance button DB2, and the car C
is lowered at a low speed, and when the upper part of the car C reaches the floor of the hall 3H, the maintenance button DB2 is released and the car C is stopped. Maintenance worker B can open door 3D and easily get into the upper part of car C.

Next, for maintenance personnel A and B in car C to get into car C, this can be easily accomplished by performing the reverse operation to that described above, so a description thereof will be omitted.

In this way, according to this embodiment, conventionally, maintenance personnel relied on the intuition of the maintenance personnel driving car C to get onto the top of car C, which was very troublesome, but this can be done easily and in a short time. You can get on board.

In this embodiment, a contact circuit using a relay is used, but it is of course possible to use a non-contact circuit using a microcomputer for position detection, etc. Further, although the stop position of the car C is indicated by lights 1 to L3, it is also possible to notify the stop position by a buzzer or a voice synthesis circuit instead.

〔Effect of the invention〕

According to the present invention, since a lighting means is provided to indicate when the floor surface of the car or the top of the car coincides with the floor surface of the hall, maintenance personnel can easily and easily climb onto the top of the car or This has the effect of allowing you to get into the car from the top of the car.
