[0002] As a core structural component in the industrial field, there are many types of wire ropes, which are mainly classified by the number of strands, diameter and twist angle. They are widely used in hoists, cranes, elevators, aerial ropeways, etc. A thick layer of oil sludge is easily deposited on the surface of the wire rope during long-term use, which makes it difficult to detect problems such as deformation, wire breakage, fatigue, and rust on the wire rope, which significantly reduces the reliability of the wire rope, greatly affecting its service life and construction safety. According to production safety requirements, it is necessary to regularly clean and maintain the lifting wire rope.

[0003] The existing wire rope decontamination methods are mainly divided into manual handheld wire brush scrubbing and machine rotating wire brush scrubbing. Among them, the use of manual handheld wire brush to clean the wire rope oil stains has the problems of high risk and high labor intensity; the use of machine rotating wire brush scrubbing has the problems of heavy and bulky machines, high cost of use, and even the wire rope needs to be disassembled for decontamination. Therefore, if a wire rope decontamination device with a variable diameter mechanism can be designed, and a decontamination knife that cooperates with the wire rope twist (the gap between two strands of wire rope) is set on the variable diameter mechanism, so that the decontamination knife moves spirally according to the twist angle of the wire rope, it will help solve the wire rope decontamination problem. In order to solve the variable diameter problem of the decontamination knife, the utility model is derived from this. Summary of the invention
