Above the bottom plate 1, there is a U-shaped frame 3. Inside the inner wall of the U-shaped frame 3, two fixed plates 4 are fixedly arranged. Between the two fixed plates 4, two rotating rods 5 are rotatably arranged. On the rod walls of the two rotating rods 5, winding reels 6 are fixedly arranged. Inside each winding reel 6, a traction rope 7 is wound. Inside the U-shaped frame 3, there is a placing box 8. On the top of the placing box 8, two fixed rings 9 are fixedly arranged. One ends of the two traction ropes 7 are fixedly provided with fixed hooks 10. Each fixed hook 10 matches the corresponding fixed ring 9. Inside the U-shaped frame 3, two T-shaped chutes are opened. The two T-shaped limiting rods 2 are both slidably embedded inside the corresponding T-shaped chutes. On the side wall of the placing box 8, two screws 11 are fixedly arranged. On the outer wall of each screw 11, a limiting tube 12 is threadedly sleeved. One end of each T-shaped limiting rod 2 is inserted into the corresponding limiting tube 12. Above the bottom plate 1, a moving mechanism is arranged. The U-shaped frame 3 matches the moving mechanism. By using the provided T-shaped limiting rods 2, screws 11 and limiting tubes 12, one ends of the two T-shaped limiting rods 2 can be smoothly inserted into the corresponding limiting tubes 12, thereby being able to limit the lifting of the placing box 8 and prevent the placing box 8 from shaking during the lifting process, thus improving the protection effect of the wind turbine hoisting and ensuring that the wind turbine can be hoisted stably.

[0028] In order to be able to adjust the position of the lifted placing box 8 during hoisting, facilitating the user to take out the hoisted wind turbine at high altitude, as shown in Figures 1-4As shown in the figure, the moving mechanism includes two mounting plates 13, a first motor 14, a lead screw 15 and a moving plate 16. The two mounting plates 13 are both fixedly arranged on the top of the bottom plate 1. The first motor 14 is fixedly arranged on the side wall of one of the mounting plates 13. The lead screw 15 is rotatably arranged between the two mounting plates 13. One end of the lead screw 15 penetrates through the corresponding mounting plate 13 and is fixedly connected to the output shaft of the first motor 14. The moving plate 16 is threadedly sleeved on the rod wall of the lead screw 15. The U-shaped frame 3 is fixedly arranged on the top of the moving plate 16. By using the provided moving mechanism, the position of the placed box 8 lifted by hoisting can be adjusted, facilitating the user to take out the hoisted fan at a high altitude.

[0029] In order to realize the reverse rotation of the two rotating rods 5 and the two winding disks 6, and thus be able to smoothly lift the placed box 8, as Figures 1-4 shown, a second motor 17 is fixedly arranged on the side wall of one of the fixed plates 4.

The rod walls of the other ends of the two rotating rods 5 both penetrate through the rear fixed plate 4 and are fixedly sleeved with gears 18. The two gears 18 are meshed and connected. By using the provided second motor 17 and the two gears 18, the reverse rotation of the two rotating rods 5 and the two winding disks 6 can be realized, and thus the placed box 8 can be smoothly lifted.

[0030] In order to be able to cover the placed box 8 and prevent the fan from falling, as Figures 1-4 shown, a cover plate 19 is hingedly arranged on the side wall of the placed box 8 through a hinge. Two lock heads 20 are fixedly arranged on the side wall of the cover plate 19. Two lock blocks 21 are fixedly arranged on the side wall of the placed box 8. Each lock head 20 matches the corresponding lock block 21. By using the provided lock heads 20 and lock blocks 21, the placed box 8 can be covered to prevent the fan from falling.

[0031] In order to be able to limit the movement of the moving plate 16 and ensure that the moving plate 16 can move stably, as Figures 1-3 shown, two U-shaped limiting rods 22 are fixedly arranged on the top of the bottom plate 1. The moving plate 16 is movably sleeved on the rod walls of the two U-shaped limiting rods 22. By using the provided U-shaped limiting rods 22, the movement of the moving plate 16 can be limited, ensuring that the moving plate 16 can move stably.
