[0002] Wind turbine towers are the main supporting equipment for wind power generation equipment. After years of operation, the surface of the tower needs to be cleaned and maintained. Especially when wind power generation equipment fails and causes leakage of lubricating oil and gearbox oil, the outer surface of the tower will be seriously contaminated. Now, for the safety of the staff, cleaning devices are used to help the staff clean the wind turbine towers.

[0003] The wind turbine tower cleaning machine is pulled up and down by a suspended traction method to clean the outer wall of the wind turbine tower. This is a new way to clean the wind turbine tower.

[0004] Therefore, a reasonable lifting device needs to be designed to enable the wind turbine tower cleaning machine to move up and down along the outer wall of the wind turbine tower. Summary of the invention

[0020] Furthermore, the wire arrangement assembly is connected to the wire storage drum 5 through a transmission assembly.

[0021] Furthermore, the wire arrangement assembly includes an optical axis 80, a reciprocating shaft 81, a sliding frame 82 and a slider 83. The reciprocating shaft 81 is rotatably connected to the mounting seat 6 through a bearing and is placed on the upper end of the wire storage tube 5. A bidirectional spiral groove is provided on the outer wall of the reciprocating shaft 81. The optical axis 80 symmetrically arranged on the upper and lower sides of the reciprocating shaft 81 is connected to the mounting seat 6. The sliding frame 82 is slidably connected to the outside of the optical axis 80. The sliding frame 82 is slidably connected to the outside of the bidirectional spiral groove of the reciprocating shaft 81 through the slider 83.

[0022] Furthermore, the outer wall of the sliding frame 82 is rotatably connected to two guide rollers 12 , and the wire rope 11 is arranged between the two guide rollers 12 .

[0028] The working principle and use process of this utility model:

[0029] The upper end of the steel wire rope 11 is fixedly connected to the top of the wind turbine tower. When the motor 2 rotates, it drives the reducer 1 to rotate, and the reducer 1 drives the wire storage drum 5 to rotate. Since the other end of the steel wire rope 11 is fixed to the outer wall of the wire storage drum 5, the steel wire rope 11 is wound around the outer wall of the wire storage drum 5 while the wire storage drum 5 rotates, so that the entire device can be moved upward; conversely, when the motor 2 rotates in the opposite direction, the entire device can be moved downward.

[0030] When the wire storage drum 5 rotates, the reciprocating shaft 81 will rotate synchronously, and the reciprocating shaft 81 will squeeze the slider 83 to move through the external bidirectional spiral groove. Since the slider 83 is fixedly connected to the sliding frame 82, the sliding frame 82 will reciprocate along the optical axis 80 to push the wire rope 11.

[0031] The two guide rollers 12 can further guide the steel wire rope 11, and the guide rollers 12 themselves can rotate to further reduce the friction between the steel wire rope 11 and the guide rollers 12;

[0032] The brake device 7 utilizes its own tension to increase the friction force on the wire storage barrel 5, thereby achieving the effects of braking and deceleration.

[0033] A plurality of pulley blocks 9 are installed at appropriate positions of the suspension seat 10 to limit the direction of the steel wire rope 11 so that the cleaning machine suspended in the air maintains a stable working posture.
