JPH1149450A - Operating device for earthquake sensing device for elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To safely confirm operation of a preliminary tremor sensing device by fitting a detachable exciting device to the case of an earthquake sensing device provided on the lower part of the elevator passage for an elevator and detecting the preliminary tremor of earthquake, and enabling start and stop of the exciting device to be remote-controlled. SOLUTION: When earthquake control operation is confirmed, at first an operator A fits an exciting device 5 to the upper part of the case of a preliminary tremor sensing device 4, and after connecting a receiver 6B to a pit receptacle, gets into a car 1. The operator runs an elevator at ordinary operation, and pushes the in-switch of a transmitter 6A during running of the car 1 to output a radio signal 6a. The receiver 6B inputting the radio signal 6a oscillates the exciting device 5. When the oscillation is transmitted to the case of the sensing device 4, the indication signal of earthquake control operation is output from the sensing device 4 to a control circuit. Then the operator A confirms that the car is stopped at the nearest floor, and completes inspection of the operation of the sensing device 4 and the acting state of control operation.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator for an elevator seismic detector.

[0002]

2. Description of the Related Art Conventionally, a seismic sensor for instructing an elevator to start seismic control operation when an earthquake occurs has been provided below a hoistway or in a machine room. The inspection method of the sensor will be described with reference to FIG.

FIG. 3 is a vertical sectional view of a lower portion of an elevator shaft showing inspection of an operation state of a conventional seismic sensor, and the vicinity of a position of a lowermost floor F below a shaft 2 where a car 1 moves up and down. The bracket 3 has a relatively high seismic wave frequency of 1 to 5 Hz.
An initial tremor sensor 4, which is a first earthquake sensor which detects an initial tremor having an acceleration of about 2.5 gal at a frequency of and outputs a signal, is installed, and is not shown above the hoistway 2 (not shown). In the machine room, the vibration of the earthquake is a predetermined value, for example, 80
A second seismic sensor (not shown) having a switch that is activated when the acceleration of the gull is detected is set.

[0004] The inspection method of the elevator seismic control operation by the operation of the initial tremor sensor 4 is as follows. An operator A who gets into the car 1 operates the car 1 and puts the ladder 3A on the pit 2A at the bottom of the hoistway 2. The worker B who rides hits the case of the initial fine movement detector 4 by hand to apply vibration, and the worker A confirms that the running car 1 stops at the nearest floor. In addition, the operation status of earthquake control operation is checked.

[0005]

In the prior art, the worker A checks the elevator operation and the seismic control operation in the car 1, and the worker B runs the car 1 in the pit 2A of the hoistway 2. Initial tremor seismic sensor 4 on a stepladder 3A inside
To operate. Thus, the worker B is the worker A
The elevator is at a normal speed (it is possible to operate at a low speed during work, but the seismic control operation can only be performed at the normal speed). This is a very dangerous operation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an actuator for an elevator seismic sensor capable of safely confirming the operation of an initial micromotion sensor.

[0007]

In order to achieve the above object, the present invention is provided below an elevator hoistway,
A first seismic sensor for detecting an initial tremor of an earthquake, a second seismic sensor installed in a machine room above the hoistway and having a switch operated with a predetermined vibration, and the first seismic sensor When the detector detects the initial tremor, it stops the running car to the nearest floor for a predetermined time and operates the switch of the second seismic sensor to stop the elevator. In the actuator,
The apparatus comprises a detachable vibration device attached to the case of the first earthquake sensor, and a switch for remotely starting and stopping the vibration device.

[0008] With this configuration, after the vibration device is attached to the first earthquake sensor, the switch is remotely operated from within the traveling car to activate the vibration device, and the first earthquake sensor is activated. Vibration similar to the initial tremor of an earthquake can be applied to the sensor, and work in the hoistway can be eliminated while the car is running, ensuring safety during work and confirming the operation of the earthquake sensor by one person. Work efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a vertical sectional view of a lower portion of a hoistway showing one embodiment of the present invention. FIG. 2 is a perspective view of a lower portion of the hoistway. The same components as those in FIG. I do.

In FIG. 1 and FIG. 2, on the upper part of the case of the initial fine motion detector 4 mounted below the hoistway 2 via the bracket 3, for example, an excitation with an acceleration of about 2.5 gal and vibrates at 3 Hz. The device 5 is mounted via a magnet (not shown),
A pit outlet 2B provided slightly above the pit 2A to which the shock absorber 2C is fixed is connected to the pit 2A.
When a predetermined radio signal 6a output by operating an on / off switch provided in A is inputted, a receiver 6B for turning on / off the power of the pit outlet 2B is connected to the vibration device 5 through a cord 5A. I have. Here, a switch is configured by the transmitter 6A and the receiver 6B.

Next, a description will be given of a method of confirming the operation of seismic control using an actuator for an elevator seismic sensor according to an embodiment of the present invention.

First, the worker A descends to the pit 2A and mounts the vibration device 5 on the upper part of the case of the initial fine motion detector 4.
After the receiver 6B is connected to the pit outlet 2B and the cord 5A is connected to a connector (not shown) of the receiver 6B, the user gets into the car 1. Next, the worker A drives the elevator in normal operation, and presses an ON switch (not shown) of the transmitter 6A while the car is running. Here, the transmitter 6A outputs a predetermined wireless signal 6a as an input command, and the receiver 6B that has received the wireless signal 6a supplies power to the vibration device 5. The vibration device 5 has an acceleration of 2.5 when supplied with power.
It vibrates at galle and 3 Hz.
In this case, the initial fine movement sensor 4 outputs to the control circuit (not shown) an instruction signal of an earthquake control operation for stopping the traveling car 1 to the nearest floor for a predetermined time, for example, three minutes.

Next, the worker A moves the car 1 to the nearest floor 3
After confirming that the operation has stopped for a minute, the operation of the initial fine movement sensor 4 and the check of the operation state of the control operation are completed.

[0015]

According to the present invention, after the vibration device is attached to the first earthquake sensor, the switch is remotely operated from within the running car to start the vibration device, and the first vibration sensor is activated. Vibration similar to the initial tremor of an earthquake can be applied to the earthquake detector, and work in the hoistway can be eliminated while the car is running.
The safety during the work can be improved, and the operation of the seismic detector can be checked by one worker, so the work efficiency is improved.
