Abstract

The invention proposes a steel wire rope broken strand detection system, including: a mechanical detection device and an optical detection device. Installed on the vertical beam of the elevator and next to the wire rope guide pulley, a rotatable detection arm is installed on the mounting base. The end of the detection arm facing away from the mounting base is used to contact the wire rope when the wire rope breaks or jumps. The distance between the detection arm and the mounting base There is an elastic piece connected between them, and a detection ring interacts with the detection arm, and the outer wall of the detection ring is recessed to form a receiving groove; the optical detection device includes: an infrared transmitter and an infrared receiver, and the infrared receiver and the infrared transmitter are installed on the mounting base , the infrared ray is located next to the wire rope guide wheel between the infrared receiver and the infrared emitter. The steel wire rope strand-broken job-hopping detection system solves the problem that a trigger part and an emergency stop switch are prone to collide in the prior art.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a detection system for wire rope broken strands and job hopping. Background technique [0002] A Chinese patent discloses a detection device for broken wires and broken strands of a steel wire rope and a car with an application number of CN201922058022.4. The detection device for broken wires and broken strands of a steel wire rope includes: a base, a trigger, a reset and an emergency stop switch, wherein The trigger is movably installed on the base, and the trigger is provided with a detection groove on the side facing the wire sheave. The detection groove is close to the outer circumference of the wire sheave and encloses a wire rope channel. The damaged wire rope drives the trigger to be displaced. The reset part acts between the base and the triggering part to drive the triggering part close to the wire sheave, and the emergency stop switch is used to detect the displacement of the t...
