The oil wiping block 603 is made of nylon cloth. An oil absorbing cotton 604 is fixedly arranged on the inner wall of the mounting groove and is in communication with the oil storage cavity 602. The oil supply component 700 comprises a piston cylinder 701 fixedly arranged on the inner bottom wall of the protective cover 401, a piston rod 702 slidingly fitted on the inner wall of the piston cylinder 701, and an oil storage tank 703 fixedly arranged on the outer surface of the protective cover 401. The surface of the piston cylinder 701 is provided with an oil inlet pipe 704 and an oil outlet pipe 705. One end of the oil inlet pipe 704 extends into the oil storage tank 703.

[0038] Specifically, when the piston rod 702 moves away from the oil inlet pipe 704, a negative pressure is generated in the piston cylinder 701, so that the rust-proof oil in the oil storage tank 703 is sucked into the piston cylinder 701 through the oil inlet pipe 704. When the piston rod 702 moves towards the oil inlet pipe 704, the rust-proof oil in the piston cylinder 701 is squeezed by the piston rod 702, so that the rust-proof oil in the piston cylinder 701 enters the two oil storage cavities 602 through the oil outlet pipe 705 and the three-way pipe 706, respectively.

One end of the piston rod 702 is fixedly connected with the surface of the first straight toothed rack 805 through an L-shaped connecting piece. The first straight toothed rack 805 and the second straight toothed rack 806 are in meshing transmission with the external gear disc 804.

[0040] Specifically, the driving cylinder 807 is elongated to drive the first guide plate 801 to move to one side of the hoisting steel rope 403. When the first guide plate 801 moves, the first straight rack 805 moves synchronously. When the first straight rack 805 moves, the outer gear disc 804 rotates. The outer gear disc 804 is in meshing transmission with the second straight rack 806, so as to drive the second straight rack 806 to move. At this time, the first guide plate 801 and the second guide plate 802 approach each other, so as to drive the steel wool brushes 502 on the two cleaning blocks 501 and the oil wiping block 603 on the oil storage box 601 to contact the hoisting steel rope 403, and maintain the hoisting steel rope 403. At the same time, when the first straight rack 805 moves, the piston rod 702 moves synchronously, so as to drive the oil supply component 700 to supply oil in the oil storage cavity 602.

[0041] The working principle of the embodiment is as follows: after hoisting is completed, the driving speed reducer 404 drives the winding roller 402 to rotate and wind the hoisting steel rope 403. Then, the driving cylinder 807 is elongated to drive the first guide plate 801 to move to one side of the hoisting steel rope 403. When the first guide plate 801 moves, the first straight rack 805 moves synchronously. When the first straight rack 805 moves, the outer gear disc 804 rotates. The outer gear disc 804 is in meshing transmission with the second straight rack 806, so as to drive the second straight rack 806 to move. At this time, the first guide plate 801 and the second guide plate 802 approach each other, so as to drive the steel wool brushes 502 on the two cleaning blocks 501 and the oil wiping block 603 on the oil storage box 601 to contact the hoisting steel rope 403. As the hoisting steel rope 403 is wound, the steel wool brushes 502 brush off the impurities on the surface of the hoisting steel rope 403. Then, the hoisting steel rope 403 cleaned by the steel wool brushes 502 passes through the oil wiping block 603. The oil wiping block 603 applies rust-proof oil to the surface of the hoisting steel rope 403, so as to maintain the hoisting steel rope 403. When the hoisting steel rope 403 is completely stored, the driving cylinder 807 is retracted, so as to drive the steel wool brushes 502 and the oil wiping block 603 on the oil storage box 601 to move away from the hoisting steel rope 403 and reset.
