Electromagnetic detection device for elevator traction steel wire rope

Abstract

The invention discloses an electromagnetic detection device for an elevator traction steel wire rope, which comprises a detection assembly and supporting assemblies, a steel wire rope penetrates through the detection assembly, the supporting assemblies are arranged on the two sides of the detection assembly, the detection assembly is rotatably connected with the steel wire rope, the detection assembly moves on the steel wire rope, and the supporting assemblies are used for fixing the position of the detection assembly in an elevator shaft. The detection assembly moves on the steel wire rope, safety detection of the steel wire rope between an elevator car and a traction system is achieved, meanwhile, the detection assembly detects the tensile force of the steel wire rope, the detection assembly stops at any position in the elevator shaft through the supporting assemblies, safety detection is more comprehensive, and the detection range is wider.

Description

technical field [0001] The invention relates to the technical field of elevator wire rope detection, in particular to an electromagnetic detection device for elevator traction wire ropes. Background technique [0002] In our daily life, we come into contact with various types of elevators, such as escalators, freight elevators and passenger elevators, among which the most widely used is the passenger elevator. As an important part of the elevator, the wire rope is considered a "highly dangerous component" and is closely related to the life of the elevator user. Therefore, the safety detection and maintenance of wire rope is extremely important. [0003] During the use of elevator wire ropes, damages such as wear, broken wires, rust, fatigue, etc. will occur, and there are also phenomena such as uneven stress on elevator wire ropes. The existence of these problems seriously affects production safety and even endangers equipment and personal safety, causing huge economic loss...

AI Technical Summary

Problems solved by technology

[0004] At present, the detection of elevator wire rope is mainly a single data detection of wire rope damage or tension, and there is no device that simultaneously detects damage, speed and tension

[0005] Moreover, most of the existing damage detection devices are fixed in the elevator shaft, so that the damage detection device detects the steel wire rope at a fixed position, so that the detection range of the damage detection device for the steel wire rope is small, and the complete safety data detection of the steel wire rope cannot be performed.
