Abstract

The invention provides a wear detection structure for a brake shoe of a brake as well as a mounting method and control method for the wear detection structure. The detection structure comprises a brake arm, a brake wheel, a brake shoe and a machine base, and further comprises a detection device; the brake shoe is arranged in the brake arm and is used for limiting the brake wheel to rotate when thebrake arm is attached to the machine base; the brake arm is elastically arranged on the side edge of the machine base; the detection device is arranged on the brake arm or the machine base; and whenthe brake shoe is worn so as to enable the brake arm and the machine base to get close to each other, the detection device is triggered to cut off power supplies between a driving main machine and thebrake. According to the wear detection structure for the brake shoe of the brake, when the brake is in an open circuit condition caused by line faults, the power supply of the driving main machine and the power supply of the brake can be cut off in time, and therefore the safety guarantee of passengers of elevators or escalators can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a brake shoe wear detection structure, an installation method and a control method thereof. Background technique [0002] In the existing elevator and escalator drive hosts, friction-type electromechanical brakes are installed on the elevator and escalator drive hosts as the braking system for the normal operation of the elevator and escalator and the safety of users; The working principle of the electromechanical brake is that when the power supply loses power or the control circuit power supply loses power, after the brake arm moves under the action of the brake spring, the brake shoe on it hugs the rotating brake wheel to achieve brake. [0003] External drum brakes, usually referred to as external drum brakes, are widely used in elevator and escalator systems because of their simple structure, low price, easy manufacturing, convenient commissioning and maintena...
