Problems solved by technology

[0003] The disadvantage of this braking system is that once the wire rope between the speed governor and the tensioner is broken or other failures occur, the braking system will fail
This will cause the running elevator car to stop suddenly, and the passengers in the car will be trapped in the car and can only wait for external rescue

Abstract

The invention discloses a fault detection device of an elevator braking control device. The fault detection device comprises at least two groups of braking components arranged on an elevator lift car,and a control unit for controlling the braking components through an electronic signal according to the information of the elevator lift car. The fault detection device of the elevator braking control device detects the fault of the elevator braking control device through the control unit by depending on the status information of an electromagnetic actuator. When the elevator braking control device breaks down, the fault detection device can ensure that the braking is still effective, and brakes an elevator after the elevator runs to the leveling of a landing, thereby preventing passengers from getting trapped.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to a fault detection device used in an elevator brake control device. The invention also relates to a fault detection method of an elevator braking control device. Background technique [0002] Current elevators generally include a safety system consisting of braking devices, mechanical overspeed governors, tensioning pulleys and wire ropes. The subsystem consisting of speed limiter, tensioner and wire rope includes two functions: one is to detect the running speed of the elevator; the other is to trigger the braking device to brake when the speed exceeds the preset speed. Generally, the overspeed governor is set on the upper part of the hoistway or the machine room floor, the tension pulley is set in the bottom pit, and the wire rope forms a closed loop between the overspeed governor and the tension pulley. When it is detected that the elevator exceeds the preset speed, the speed limiter ...
