Abstract

PROBLEM TO BE SOLVED: To elimnate the necessity of lighting in inspection lamps by turning on a switch in an operation board by entering a car by manually opening a car door, by constituting so that the inspection lamps above and below the car are automatically lighted when an earthquake sensor operates. SOLUTION: An earthquake occurs, and when an earthquake sensor operates, a contact point 11a is closed, and relay 12 is energized. Then, a contact point 12a1 is closed, and an earthquake control operation circuit 13 becomes effective, and a car is made to perform earthquake control operation. On the other hand, since a contact point 12a2 is also closed, even if a contact point 10 of a switch in an operation board is opened, inspection lamps 8 and 9 are lighted. Then, when a maintenance engineer hastens to restore the earthquake control operation circuit 13, the inspection lamps 8 and 9 are lighted. Therefore, when a landing door is opened, since the inside of a hoistway above and below the car is illuminated by the inspection lamps 8 and 9, a pit and an apparatus can be easily inspected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator seismic control operation device suitable for restoration after an elevator seismic control operation.

[0002]

2. Description of the Related Art In an elevator, when an earthquake occurs and the seismic detector operates, seismic control operation is performed, the car stops at the nearest floor, and after the passengers have been dropped off, the car becomes dormant at that floor. When the elevator becomes dormant, the manager notifies the elevator maintenance company that seismic control operation has been performed.

Therefore, a maintenance engineer rushes to the site and first opens the landing door on the first floor, inspects the pit, climbs the stairs, manually opens the elevator car door, and operates the switch in the operator's panel. Then turn on the inspection lights above and below the car. Then, open the landing door on the car, inspect the equipment on the car, go to the machine room, inspect the equipment, make sure that there is no abnormality in the equipment, restore the seismic detector to normal, Perform normal operation, make sure that the elevator is operating normally, and then restore normal operation.

A technique of this kind is described in, for example, Japanese Patent Laid-Open No. 56-113673.

[0005]

In the prior art, the car door must first be manually opened to turn on the inspection lamp, but the car door is electrically biased by a braking torque when stopped. Therefore, there is a problem that it is very heavy to manually open the car door, and it is difficult to open the car door.

In view of the above drawbacks, it is an object of the present invention to provide an elevator seismic control operation device capable of turning on a check light when the seismic control operation is restored without opening the car door.

[0007]

[Means for Solving the Problems] The purpose of the present invention is to provide a check light above and below the car in a seismic control operation device for an elevator that stops the car after stopping the car at a predetermined floor when the seismic detector operates. And a means for turning on the inspection light when the seismic detector operates.

Therefore, according to the present invention, when the earthquake occurs, the seismic detector operates, and the car is not operating on the predetermined floor, the inspection light is on, so the car door is purposely manually operated. There is no need to open and turn on the check light. Therefore, the labor of the maintenance engineer can be reduced.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS.

FIG. 2 shows a schematic sectional view of the elevator car and hoistway. In the figure, 1 is a hoistway, 1F to 3F
Are floors of the first to third floors, 1H to 3H are hall doors of the first to third floors, 2 is a machine room, 14 is a pit, 3 is a drive machine provided in the machine room, and a car in the hoistway 1 4 is connected to the balance weight 6 via the drive machine 3 by the rope 5, and the car 4 stops at the predetermined floors 1F to 3F as the drive machine 3 rotates. A car door 7 is engaged with the landing doors 1H to 3H at the time of landing, and opens and closes in synchronization. Reference numerals 8 and 9 are inspection lights for inspecting the hoistway 1 provided on the upper and lower portions of the car 4, and when the switch 10 in the operation panel (not shown) in the car 4 is turned on, the inspection lights 8 and 9 are turned on. An earthquake detector 11 is provided in the machine room 2.

FIG. 1 is an electric circuit diagram of an elevator seismic control operation system according to the present invention. In the figure, P and N are DC power supply terminals, 11a is an a contact that is closed when the earthquake detector operates, 12 is a relay that is energized when the contact 11a is closed, and 12a ₁ and 12a ₂ are the a contacts, 13 Is an earthquake control operation circuit, 10a is an a contact of the switch 10, and a contact 10
The contact a and the contact 12a ₂ are connected in parallel.

Next, the operation of this embodiment will be described.

Now, when an earthquake occurs and the earthquake detector 11 operates, the contact 11a is closed and the relay 12 is energized. Therefore, the contact 12a ₁ is closed and the seismic control operation circuit 13 is activated, and the car 4 performs seismic control operation, and, for example, the second floor 2
Suppose you stopped at F. On the other hand, since the contact 12a _{2 is} also closed, the check lights 8 and 9 are lit even if the switch 10 is open.

Therefore, when the maintenance engineer rushes to the site to restore the seismic control operation circuit 13, the inspection lights 8 and 9 are turned on. Therefore, the first floor hall door 1H
Since the inside of the hoistway 1 under the car is illuminated by the inspection lamp 9 when the door is opened, the pit 14 can be easily inspected. Similarly, when the landing door 3H on the third floor is opened, the inspection light 8
This allows you to easily inspect the equipment on the car.

[0015]

As described above, according to the present invention, the inspection lights above and below the car are automatically turned on when the seismic detector operates, so that the car door can be opened and the inside of the car can be opened. There is an effect that it is not necessary to turn on the switch in the operation panel to reduce the labor of the maintenance technician and the work time.
