DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figs. 1-2 As shown, the crane sling cleaning device of this embodiment includes a base 1, a support arm 2, a lifting arm 3, a winding motor 4, a winding roller 5, a cable 6, and a hook 7. A first guide roller 8 located on the left side and a second guide roller 9 located on the right side are rotatably mounted at the bottom of the support arm 2. A cleaning mechanism 10 is positioned between the first guide roller 8 and the second guide roller 9. The cleaning mechanism 10 includes a housing 1001, openings 1002 on the left and right sides of the housing 1001, limiting rollers 1003 at the openings 1002, bidirectional threaded rods 1004 symmetrically arranged vertically within the housing 1001, movable blocks 1005 meshing with the outer walls of the bidirectional threaded rods 1004, and brush plates 1006 fixedly mounted on one side of the movable blocks 1005. The second guide roller 9 is connected to the bidirectional threaded rods 1004 via a belt and pulley. This device can clean the cable in both the length direction and the direction perpendicular to the cable during cable movement.

[0021] Furthermore, a through hole 11 is provided at the bottom of the outer casing 1001, and a material discharge groove 12 is provided at the bottom of the through hole 11.

[0022] Furthermore, a slide rod 13 is fixedly installed in the inner cavity of the outer shell 1001, and the slide rod 13 passes through the movable block 1005 and is slidably connected to the movable block 1005.

[0023] Furthermore, a third guide roller 14 is also provided on the outer wall of the support arm 2.

[0024] Working principle: When the cable is being wound up or down, the friction between the cable and the second guide roller 9 causes the second guide roller 9 to rotate. When the second guide roller 9 rotates, it drives the bidirectional threaded rod 1004 to rotate through the belt and pulley. The bidirectional threaded rod 1004 drives the movable block 1005 to move back and forth. During the reciprocating movement of the movable block 1005, it drives the brush plate 1006 to move back and forth. During the reciprocating movement of the brush plate 1006, the cable is cleaned during the movement. The cleaning can be displayed in the length direction and vertical direction of the cable.
