Problems solved by technology

However, the intelligence level of existing emergency rescue devices is low. Once an accident occurs, the device will directly energize the brake of the traction machine after it is put into operation, regardless of whether there are people trapped in the bridge compartment, so that the elevator runs to the leveling floor. open the door
The emergency rescue device generally supplies power to the elevator system through the battery, which will cause waste of electricity in the battery and affect the standby time of the emergency rescue device.
In addition, since the current emergency rescue devices do not monitor the voltage and capacity of the battery, the rescue device will cause rescue risks due to the insufficient battery capacity of the battery during use, and the safety is poor.
Therefore, the existing rescue devices have the problems of low intelligence and poor safety.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0023] Example. A kind of emergency rescue method of elevator, constitutes as figure 1 shown, including the following steps:

[0024] ①The rescue device starts after the elevator is powered off. After the rescue device is started, it first detects its own voltage through the voltage detection relay. When the detected value is lower than the minimum pull-in voltage of the elevator brake, directly enter step ⑤. When the minimum pull-in voltage is reached, enter the next step;

[0025] ②The rescue device detects the load in the car. When there is no load in the car, go directly to step ⑤. When there is a load in the car, go to the next step;

[0026] ③The rescue device detects the position of the elevator in the well, and when the elevator is in the leveling position, enter the next step; when the e...

Abstract

The invention discloses an elevator emergency rescue method and device. The method comprises the following steps that after an elevator is powered off, a rescue device is started, the rescue device detects the voltage of the rescue device after being started, when the detection value is not lower than the lowest pull-in voltage of an elevator brake, the rescue device detects the load in the elevator, when the elevator is loaded, the rescue device detects the position, in a shaft, of the elevator, when the elevator is located in the non-level position, the rescue device provides power for the elevator brake; and the elevator brake drives the elevator to the level position; after the rescue device stops providing power for the elevator brake and supplies power to a portal crane so that the landing door can be opened, and trapped persons leave the elevator through the landing door; and after the trapped persons leave completely, the rescue device stops the elevator. The elevator emergencyrescue method and device have the characteristics that the intelligent degree is high, and the safety is good.

Description

technical field [0001] The invention relates to an elevator emergency rescue method, in particular to an elevator emergency rescue method and device. Background technique [0002] Elevator emergency rescue device is a kind of emergency rescue equipment for elevator trapped people. Its main function is to automatically switch and cut off the original electric control system when the AC power supply suddenly fails or the electric control system fails to stop the bridge car in the shaft during the operation of the elevator. The system supplies the AC power to the elevator and pulls the car to the leveling position to open the door, so that the user can escape from danger. However, the intelligence level of existing emergency rescue devices is low. Once an accident occurs, the device will directly energize the brake of the traction machine after it is put into operation, regardless of whether there are people trapped in the bridge compartment, so that the elevator runs to the le...
