After assembly, the movable disk 2 is rotated by controlling the driving rod 12, and the rotation of the movable disk 2 drives the six pinions 4 to rotate synchronously, and the six pinions 4 will drive the six meshed racks 3 to rotate synchronously in the dovetail groove 1 on the fixed disk 1 03 slides freely on the surface of the six racks 3, so that the cleaning knives 6 on the six racks 3 contact the surface of the wire rope 5. The six cleaning knives 6 will contact the surface of the wire rope 5. Adjust the preload force of the cleaning knife and the wire rope. Lock the fixed disk 1 and the movable disk 2 through the locking mechanism. Add an axial limiter 10 under the cleaner and hang it on the bracket through a ring. When the wire rope 5 moves downward, the axial limiter 10 prevents the wire rope 5 from driving the cleaner to descend, and converts the spiral descending motion of the cleaner during cleaning into a rotational motion on the plane, thereby achieving continuous cleaning. It is worth noting that wire ropes 5 of different sizes can be set up according to the above steps and the corresponding cleaning knives 6 are replaced to achieve the purpose of changing the diameter to adapt to the cleaning work of wire ropes 5 of different sizes.
