The invention provides a steel wire rope strand breaking and groove falling detection system which comprises a mechanical detection device and an optical detection device, wherein the mechanical detection device comprises a mounting base, an elastic piece, a detection arm, a detection ring and a self-resetting switch, the mounting base is used for being mounted on an elevator vertical beam and located beside a steel wire rope guide wheel, a rotatable detection arm is mounted on the mounting base, one end, deviating from the mounting seat, of the detection arm makes contact with a steel wire rope when the steel wire rope breaks strands or falls out of a groove, the elastic piece is connected between the detection arm and the mounting base and acts with the detection arm to form a detectionring, an outer wall of the detection ring recesses to form an accommodating groove, the optical detection device comprises an infrared emitter and an infrared receiver, the infrared receiver and the infrared emitter are arranged on the mounting base, and infrared rays between the infrared receiver and the infrared emitter are located beside the steel wire rope guide wheel. The steel wire rope strand breaking and groove falling detection system solves the problem that in the prior art, a triggering piece and an emergency stop switch are easily collided.
Description
technical field [0001] The invention relates to the field of elevators, in particular to a detection system for steel wire rope broken bones 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 t...
