The cleaning component 59 on the moving box 55 cleans each rope groove 21 of the traction wheel 2 in turn along the axial direction of the traction wheel 2. In this way, the cleaning component 59 forms regular interval contact with each rope groove 21 on the traction wheel 2, ensuring that the sludge in a single rope groove 21 is cleaned while the traction wheel 2 rotates, and the contact time between the traction wheel 2 and the traction wheel 2 during operation is reduced, thereby increasing the service life of the cleaning component 59 and ensuring the Cleaning efficiency: Specifically, when cleaning the first rope groove 21 of the traction wheel 2, the first cleaning plate 596 is embedded in the first rope groove 21, and the second cleaning plate 597 is distributed on the outside of the first rope groove 21. The moving box 55 is moved one station along the axial direction of the rotating shaft 53, and the second cleaning plate 597 is embedded in the second rope groove 21. The first cleaning plate 596 is distributed on the outside of the second rope groove 21. Therefore, during the movement of the moving box 55 along the axial direction of the traction wheel 2, the first cleaning plate 596 and the second cleaning plate 597 are sequentially embedded in the rope groove 21 of the traction wheel 2, and the operation of the driving motor 51 is stopped intermittently. The length of the intermittent time is the number of rotations of the traction wheel 2, so that the first cleaning plate 596 or the second cleaning plate 597 can clean the internal sludge after being embedded in the rope groove 21. It is convenient to use, durable, and has low cost.

[0021] Specifically, the reversing assembly 57 includes a first bevel gear 571, a second bevel gear 572, a third bevel gear 573, a gear 574, a rack 575, a connecting shaft 576, a lever 577, a second sleeve 578, a reversing sleeve 579 and two stoppers 580.
