Description

Technical Field

[0001] The utility model belongs to the technical field of elevator maintenance, and particularly relates to an elevator wire rope dirt cleaning detection device. Background Art

[0002] Elevator wire rope is a tool that transmits power by friction. It works frequently and runs at a high speed, which requires good friction between the wire rope and the traction wheel. Since the wire rope is composed of multiple wires, under working conditions, wire rope grease can reduce the friction between the wires while ensuring the friction between the wire rope and the traction wheel, effectively extending the service life of the wire rope. However, grease will absorb a lot of dust to form sludge, so the elevator wire rope needs to be cleaned.

[0003] The Chinese patent with publication number CN214638428U discloses an elevator wire rope oil removal device, in which a cylindrical brush is arranged between two plate brushes, so that the circumference of the wire rope can be cleaned by the cylindrical brush, reducing the impact of oil sludge on the elevator wire rope. However, in this scheme, since the wire rope works frequently, the oil is removed by friction between the wire rope and the cylindrical brush, resulting in serious damage to the cylindrical brush, and the cylindrical brush needs to be replaced frequently, affecting the normal operation of the elevator.
