Description

Technical Field

[0001] This utility model relates to the field of wind turbine nacelle transportation technology, and more specifically, it relates to a transportation tool for wind turbine nacelles. Background Technology

[0002] A wind turbine nacelle is a housing used to house and protect the main shaft, gearbox, engine, and other electrical equipment in a wind turbine generator set, ensuring that the wind turbine generator set can operate normally in harsh weather conditions. When transporting a wind turbine nacelle, transport fixtures are generally used to secure it to facilitate subsequent long-distance transportation.

[0003] However, most traditional transport fixtures are simple plates or brackets, which are then fixed by ropes. However, this type of transport fixture has a relatively simple structure and cannot adjust the installation position of the ropes according to the length of the wind turbine nacelle, making it inflexible in use.

[0004] Furthermore, lacking a protective structure, the wind turbine nacelle is vulnerable to impacts from stones and other debris during transportation due to the long distances involved and the fact that wind turbines are typically installed in relatively desolate locations. This impacts the overall quality of the nacelle. Utility Model Content

A mounting frame 9 is fixedly installed at one end of the trolley 1. A roller 10 is rotatably installed inside the mounting frame 9. A rolling plate 11 is provided on the outer wall of the roller 10. One end of the roller 10 passes through the mounting frame 9 and is fixedly equipped with a handwheel 24.

[0031] In this embodiment, T-shaped grooves 12 are provided on the upper end face and both sides of the guard plate 2. T-shaped blocks 13 are slidably provided inside the T-shaped grooves 12. Clamping plates 14 are fixedly provided on the upper end face of the T-shaped blocks 13. Receiving grooves 15 are provided on the inner wall of the clamping plates 14. The two sides of the rolled plate 11 can enter the interior of the receiving grooves 15. A connecting block 16 is fixedly provided at one end of the clamping plate 14. The connecting block 16 is fixedly installed to the outer wall of the guard plate 2 with screws. A limiting block 25 is fixedly provided at one end of the rolled plate 11.

[0032] More specifically, the user can adjust the distance between the sliding block 5 and the sliding hole 3 by rotating the adjusting nut 8. Then, the rope is fixed to the rope hook 7 and tied tightly to secure the wind turbine nacelle on the upper end of the cart 1, which facilitates subsequent transportation. When the wind turbine nacelle is fixed on the upper end of the cart 1, the roller 10 can be rotated by rotating the handwheel 24 to release the rolled plate 11 and place it on the upper end of the wind turbine nacelle. Then, the clamping plate 14 is moved by the cooperation of the T-block 13 and the T-slot 12 so that both sides of the rolled plate 11 enter the receiving groove 15. At the same time, the limiting block 25 at one end of the rolled plate 11 is also located at one end of the clamping plate 14 to achieve the effect of limiting and fixing the rolled plate 11, thereby protecting the upper part of the wind turbine nacelle, reducing the impact of external objects such as stones, and facilitating subsequent normal installation.

[0033] Please see Figure 1 , Figure 4 and Figure 5 As an implementation method for limiting the tail of the wind turbine nacelle: a guide hole 17 is provided on the lower end face of the board 1 and on one side. A guide block 18 is slidably provided inside the guide hole 17. A baffle 19 is fixedly provided on the upper end face of the guide block 18.

[0035] Please refer to Figure 1 As a further embodiment for fixing the flatbed cart 1 to the transport equipment: a connecting block 26 is fixedly provided on the outer wall of the flatbed cart 1.

[0036] Specifically, users can use connecting blocks 26 to fix the flatbed cart 1 to the transport equipment to facilitate the subsequent transport of the wind turbine nacelle.

[0037] In summary, when using the overall equipment: the user can first place the wind turbine nacelle on the upper end of the cart 1 using the lifting equipment, and then control the motor 23 to rotate the lead screw 21. At this time, the lead screw 21 will drive the baffle 19 to move through the moving block 22 to adjust its position, thereby limiting the baffle 19 on one side of the wind turbine nacelle. Then, the binding rope is fixed to the rope hook 7 and tied tightly to achieve the effect of fixing the wind turbine nacelle on the upper end of the cart 1.

The wind turbine nacelle is fixed in place. After the wind turbine nacelle is fixed, the roller 10 can be rotated by turning the handwheel 24 to release the roll plate 11, which is then positioned at the upper end of the wind turbine nacelle. Then, the clamping plate 14 is moved by the cooperation of the T-block 13 and the T-slot 12 so that both sides of the roll plate 11 enter the receiving groove 15. The clamping plate 14 is then fixed with screws. At the same time, the limiting block 25 at one end of the roll plate 11 is also located at one end of the clamping plate 14 to achieve the effect of limiting and fixing the roll plate 11, thereby protecting the upper part of the wind turbine nacelle, reducing the impact of external objects such as stones, and facilitating normal transportation.
