Problems solved by technology

If the brake is not fully opened or the brake is not at zero speed during normal operation of the elevator, the brake pads of the traction machine will wear out. Excessive wear will lead to a decrease in the braking torque of the traction machine, resulting in a slipping accident of the main engine

Abstract

The invention discloses an elevator, comprising a traction machine (1), a traction steel rope (2), a lift car (3), a compensation device (4) and a counterweight system (5); the traction machine (1) comprises a traction machine main body (6), a traction wheel (12), a brake wheel (9), a brake arm (7) and a brake element (8); the brake element (8) comprises a brake base (14), a brake sticking brake pad (13), at least a pair of insulators (15) embedded in the brake base (14) at intervals, at least one pair of conductors (17) wrapped in the pair of insulators (15) in a one-to-one-correspondence manner and cables (16) connected with all conductors (17); the cables (16) connected onto the at least one pair of conductors (17) are connected into a safety loop of an elevator control system, and the at least one pair of conductors (17) send a signal for switching off the safety loop after conduction. According to the elevator, a signal for switching off the safety loop of the elevator control system can be sent when the brake sticking brake pad is worn to preset thickness, so that the elevator stops operation, and operation safety of the elevator is improved.

Description

technical field [0001] The invention relates to an elevator, especially a safety circuit that can automatically detect the wear of the brake pad of the traction machine and cut off the elevator control system after the brake pad is worn to a preset thickness elevator. Background technique [0002] Generally speaking, the traction machine of a traditional elevator only performs signal judgment processing on the action position of the brake, but does not effectively detect the wear of the brake. If the brake is not fully opened or the brake is not at zero speed during normal operation of the elevator, the brake pads of the traction machine will wear out. Excessive wear will lead to a decrease in the braking torque of the traction machine, resulting in a slipping accident of the main engine . Contents of the invention [0003] In view of this, the purpose of the present invention is to overcome the defects of the prior art and provide a safer elevator, which can automatical...
