Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rescue operation device for an elevator, and more particularly to a rescue operation device for an elevator that stops a rescue car in the vicinity of a malfunctioning car.

[0002]

2. Description of the Related Art As described in Japanese Patent Laid-Open No. 56-52376, a conventional apparatus detects the deceleration start position of a rescue car by the relative position of a car that has failed and stopped, and from the time when the deceleration start position is detected. A stop command is generated after a predetermined time period, the rescue car is stopped in the vicinity of the malfunctioning car, and passengers of the malfunctioning car are rescued.

[0003]

In the above-mentioned conventional technique, the deceleration start position of the rescue car is detected, the rescue car is decelerated, and the rescue car is stopped after a predetermined time. There may be an error in the position, and when moving the passenger in the car that has stopped due to failure to the rescue car by a trap or the like from the rescue exit, if the passenger is frightened looking at the lower part of the tower and further the slope of the trap is generated. There was a problem that I felt more dangerous and my legs were freezing, and I could not walk the ramp.

An object of the present invention is to provide an elevator rescue operation device capable of preventing an error from occurring in a stop position depending on whether a rescue car or a breakdown stop has occurred.

[0005]

In order to achieve the above object, a plurality of elevators are installed side by side, and relative position detecting means for detecting a relative position of a car that has stopped due to failure and a car for rescue and outputting a signal. , Having position detecting means for detecting the car position by taking in a position signal that always follows the car position,
In an elevator rescue operation device in which another adjacent one of the elevators performs a rescue operation when one of the elevators fails and stops, the rescue car detects an output signal of a relative position detecting means of the car that has stopped due to the failure. Then, the nearest floor stop means for stopping to the nearest floor, the arithmetic processing means for arithmetically processing the position signal of the position detecting means and the output signal of the relative position detecting means, and for obtaining the stop position of the car that has stopped due to the failure. , A rescue operation stop position command circuit for instructing the stop position of the car that has stopped due to the failure to the elevator performing the rescue operation.

[0006]

Since the present invention is configured as described above, during the rescue operation, the rescue car stops at the nearest floor by the output signal of the relative position detecting means, and the output signal and the position of the relative position detecting means. The position signal of the detection means is used to perform arithmetic processing on the position of the car that has stopped due to failure, and the rescue operation stop command circuit issues a command to the elevator that performs rescue operation to stop the rescue car at the same position as the position of the car where the failure has stopped. Since it is given, the floor positions of the rescue car and the breakdown car are the same, and passengers can safely move to the rescue car.

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

When the faulty car 1 is stopped, the light projecting section 2 of the faulty car 1 emits a light beam 3. Further, when the rescue car 4 rises, a pulse signal is output from the rotary encoder 5 directly connected to the shaft of the hoisting machine (not shown), and this rotary encoder determines the position of the rescue car 4 in the tower (not shown). The encoder 5 is connected to a position detection circuit 6 that calculates and calculates an output pulse signal. This position detection circuit 6 is connected to the elevator control circuit 7,
The position of the rescue car 4 is output to the control circuit 7 on an hourly basis. Further, an elevator stop position formed by operating a hall call button (not shown) or a car call button (not shown), that is, a stop command signal and an elevator control circuit 7 that are changed by the elevator stop position command circuit 8 in the response order of the rescue car 4 Has been output to.

Further, the light receiving section 9 of the rescue car 4 outputs a signal when the light beam 3 of the light projecting section 2 is input, and is connected to a nearest floor stop circuit 10 for stopping the rescue car 4 to the nearest floor. There is.
Here, the light projecting unit 2 and the light receiving unit 9 are relative position detecting means. The nearest floor stop circuit 10 is connected to the stop position command circuit 8.

The position signal of the rescue car 4 of the position detection circuit 6 and the output signal of the light receiving unit are input to the failure car stop position detection circuit 11 which is the arithmetic processing means, and the stop position of the failure car 1 is calculated. Further, the failure car stop position detection circuit 11 calculates the distance between the position of the failure car 1 and the nearest floor 13 where the rescue car 4 has stopped, and outputs the distance data to the rescue operation stop position command circuit 12, Rescue operation stop position command circuit 12
Is the most suitable for running the rescue car 4 from the floor 13 to the stop car 1 from the input distance data, calculates the speed curve that reaches acceleration, steady running, deceleration, and stop that arrives in the shortest time, and controls the elevator. Output to the circuit.

Next, the operation will be described.

Now, as shown in FIG. 2, when the faulty car 1 stops with passengers (not shown) on board, and the rescue car 4 rises during steady running with a rescuer (not shown) on it, the rotary encoder 5 positions the pulse signal. When output to the detection circuit 6, and when the rescue car 4 comes to a position facing the faulty car 1 as shown in FIG. 3, the light beam 3 from the light projecting unit 2 is detected by the light receiving unit 9, and the light receiving unit 9 outputs a signal. It outputs to the nearest floor stop circuit 10 and the failure car stop position detection circuit 11, the nearest floor stop circuit 10 outputs the nearest floor stop signal to the elevator stop position command circuit 8, and the stop position command circuit 8 outputs the elevator. The speed curve for stopping at the nearest floor is calculated and output to the control circuit 7, and the rescue car 4 is stopped at the floor 13, which is the nearest floor, as shown in FIG.
On the other hand, the failure car stop position detection circuit 11 calculates the signal of the position detection circuit 6 and the signal of the light receiving unit 9 to calculate the distance of the failure car 1 from the floor 13, and based on the calculation result, the floor 13
The rescue operation stop position command circuit 12 obtains a speed curve for traveling from the vehicle to the stop position of the defective car 1 and outputs the speed curve to the elevator control circuit 7 to set the rescue car 4 to the stop position of the defective car 1 as shown in FIG. After stopping, the rescuer (not shown) passes the trap 4a of the rescue car 4 to the side of the failed car 1, opens the side plate (not shown) of the failed car 1, and moves the passenger (not shown) to the rescue car 4.

According to the present invention, the rescue car 4 is the defective car 1
When the stop position of the car 1 is detected, the traveling speed can be maintained at a steady speed, and when the stop position of the faulty car 1 is detected, the rescue car 4 is stopped to the nearest floor, and the faulty car 1 is stopped from the nearest floor.
Since the rescue operation stop position command circuit 12 decelerates the speed curve that is optimal to the stop position and can travel in the shortest time, the rescue time can be shortened.

[0014]

According to the present invention, since a command is given to stop the rescue car at the same position as the position of the car that has stopped due to failure, the floor positions of the rescue car and the failure stop car are equal, and passengers are You can safely move to the rescue basket.
