[0026] Embodiment 1

[0027] As Figures 1 - 5As shown

[0028] A hub blade assembly device for a wind turbine, comprising a fixing frame 1, a tray 2 and a support arm 3. The tray 2 is rotatably arranged on the fixing frame 1, and the end of the support arm 3 is connected to the side wall of the fixing frame 1.

[0029] Legs 21 are provided on the bottom wall of the support arm 3 and the bottom wall of the fixing frame 1. A slide rail 4 is provided on the top of the support arm 3. A slide seat 5 is arranged on the slide rail 4. An expansion member 6 is provided on the slide seat 5. A support plate 7 is provided on the expansion member 6. The slide seat 5 is installed on the slide rail 4, allowing the support plate 7 to move horizontally along the slide rail, further finely adjusting the position of the blade to ensure that the blade can be accurately inserted into the hub.

[0030] During use, place the hub on the tray 2 and the blade on the support plate 7. Slide the slide seat 5 on the slide rail 4 and adjust the height of the blade through the expansion member 6. Cooperate with rotating the tray 2 to precisely control the blade for positioning and installation.

[0031] As Figure 2 shown, a rotating shaft 8 is fixedly connected to the bottom wall of the tray 2. The rotating shaft 8 rotatably penetrates through the fixing frame 1 via a bearing and extends out. A driving member 9 is provided at the bottom end of the rotating shaft 8. The tray 2 is fixed on the fixing frame 1 through the rotating shaft 8. The rotation of the rotating shaft 8 is supported by the bearing, ensuring the smooth rotation of the tray 2, so as to accurately adjust the position of the hub.

[0032] As Figure 3 shown, a number of hanging rings 10 are provided on the fixing frame 1, the tray 2, the support arm 3 and the support plate 7. The hanging rings 10 on the fixing frame 1 and the support arm 3 facilitate the hoisting of the fixing frame 1, and the hanging rings 10 on the tray 2 and the support plate 7 facilitate the fixing of the hub and blades of the wind turbine through external ropes, so as to improve the stability during hoisting and installation.

[0033] As Figure 2 shown, the driving member 9 includes a worm gear 11, a worm 12 and a driving motor 13. A support plate 14 is provided on the bottom wall of the fixing frame 1. The worm gear 11 is fixedly sleeved on the rotating shaft 8. The two ends of the worm 12 are rotatably arranged on the support plate 14. The worm gear 11 is in mating connection with the worm 12. The driving motor 13 is arranged on the support plate 14. The output end of the driving motor 13 rotatably penetrates through the support plate 14 and is connected to the worm 12. Start the driving motor 13 to drive the worm 12 to rotate, then the worm gear 11 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the tray 2 to rotate to cooperate with the installation and positioning of the blade. The cooperation of the worm gear and the worm can convert the high-speed rotation of the driving motor into the low-speed high-torque rotation of the rotating shaft, and can accurately control the rotation angle of the tray to adapt to different assembly requirements.

[0034] As Figure 3As shown, the telescopic member 6 includes an electric telescopic rod 15. The fixed end of the electric telescopic rod 15 is provided on the top wall of the sliding seat 5, and the movable end of the electric telescopic rod 15 is fixedly provided on the bottom wall of the support plate 7. The electric telescopic rod 15 can adjust the height of the support plate 7. The electric telescopic rod 15 can adjust the height of the support plate 7, which is crucial for accurately aligning the blade to a specific height of the hub.

[0035] As Figure 3 shown, there are two groups of sliding seats 5. A connecting member 16 is provided between the two groups of sliding seats 5. The connecting member 16 includes a connecting rod 17. A fixing block 18 is provided on the side wall of the sliding seat 5. One end of the connecting rod 17 is provided on the side wall of one group of fixing blocks 18, and the other end of the connecting rod 17 slides through the other group of fixing blocks 18 and extends out. A number of screw holes 19 are provided on the connecting rod 17. A fastening bolt one 20 is threadedly connected to the fixing block 18, and the fastening bolt one 20 is threadedly connected to the screw hole 19. By screwing out the fastening bolt one 20, the distance between the two sliding seats 5 can be adjusted to facilitate fixing the blade according to the blade length and improve the stability of the blade support.

[0036] As Figure 5 shown, a clamping groove 22 is provided at the end of the support arm 3, and an insertion block 23 is provided on the side wall of the fixing frame 1. The insertion block 23 is inserted into the clamping groove 22. A fastening bolt two 24 is threadedly connected to the support arm 3 and the insertion block 23. The support arm 3 is fixed to the fixing frame 1 by the fastening bolt two 24. Screwing out the fastening bolt two 24 can separate the support arm 3 and the fixing frame 1.

[0037] During specific use:

[0038] Place the hub on the tray 2 and the blade on the support plate 7. The electric telescopic rod 15 can adjust the height of the support plate 7 to adjust the height of the blade so that the installation end of the blade corresponds to the hub. Push the blade, then the sliding seat 5 slides on the slide rail 4 and the blade can be inserted into the hub, thereby accurately positioning the blade. And by cooperating with starting the driving motor 13 to drive the worm 12 to rotate, the worm gear 11 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the tray 2 to rotate to cooperate with rotating the hub, and then the installation positioning of multiple fan blades on the hub can be carried out.

[0039] In the above embodiment, the support arm, the fixing frame and the slide rail are made of high-strength steel or composite materials for the key load-bearing components to improve the durability and load-bearing capacity of the entire system. Anti-corrosion treatment is carried out on key metal components such as the support arm, the fixing frame and the slide rail, especially when used outdoors or in harsh environments, which can extend the service life of the equipment and reduce the maintenance requirements.

[0040] In the above embodiment, the worm and worm gear components used can also be replaced with a precision gearbox. Changing the worm and worm gear transmission system to a precision gearbox can reduce backlash and improve the transmission accuracy and efficiency.

[0041] In the above embodiments, to enhance the safety of the device during use, a plurality of emergency stop buttons are configured on the device. The emergency stop buttons are used to emergently supply power to the electric telescopic rod or the drive motor, ensuring that in any abnormal situation, the operator can quickly cut off the power supply and stop the machine operation.

[0042] In the present utility model, the hub is placed on the tray and the blade is placed on the pallet. The blade can be precisely controlled by sliding the sliding seat on the slide rail and adjusting the height of the blade through the telescopic member, and cooperating with the rotating tray for positioning and installation, which not only improves the assembly accuracy and efficiency, but also greatly reduces the risk during operation.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
