[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the utility model, a wind turbine blade lifting device includes a base plate 8. An electric push rod 9 is rotatably mounted on one side of the top of the base plate 8. A second support plate 7 is rotatably mounted on the push rod end of the electric push rod 9. A support rod 11 is fixedly mounted on the other side of the top of the base plate 8. One end of the support rod 11 is rotatably connected to the second support plate 7. A sliding groove 12 is provided on the top of the second support plate 7. Vertical plates 4 are symmetrically arranged on the top of the sliding groove 12. A first support plate 3 is fixedly mounted on the top of each of the two vertical plates 4. A support seat 2 is fixedly mounted on the top of the first support plate 3. An mounting plate 14 is fixedly mounted on the top of the support seat 2. A bolt 1 is threadedly connected to the mounting plate 14. A pressing plate 15 is rotatably mounted on one end of the bolt 1.

[0021] A rubber pad 6 is fixedly installed on the top of the second support plate 7. A slide groove 12 is fixedly installed on the top of the rubber pad 6. A motor 13 is fixedly installed on one side of the top of the slide groove 12. A bidirectional lead screw 5 is fixedly installed on the output shaft of the motor 13. The positive and negative threads of the bidirectional lead screw 5 are respectively threaded to two vertical plates 4. Both vertical plates 4 are slidably connected to the slide groove 12, which realizes the effect of fixing wind turbine blades of different sizes.

[0022] A first soft pad 16 is fixedly installed at the bottom of the extrusion plate 15, and a second soft pad 17 is fixedly installed on the top surface of the support base 2, which greatly reduces the friction between the clamping surface and the surface of the wind turbine blade.

[0023] The bottom of the base plate 8 is equipped with four rotating rollers 10 with brakes at the four corners. The second support plate 7 is symmetrically fixed with handles on one side, which facilitates the movement and fixation of the device.

[0024] A battery is fixedly installed on the top of the base plate 8, and a switch is fixedly installed on the top of the rubber pad 6. The motor 13 and the electric push rod 9 are both electrically connected to the switch through wires, and the switch is electrically connected to the battery through wires.

[0025] The working principle of this utility model is as follows:

[0026] The lifting device in this application is only suitable for small wind turbine blades. When using this invention, the wind turbine blade is suspended on one side of two support seats 2. The distance between the two support seats 2 is adjusted according to the length of the wind turbine blade. The adjustment is achieved by starting the motor 13, which drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 drives the two vertical plates 4 to move closer or further apart under the guidance of the slide groove 12. This allows the device to accommodate wind turbine blades of different sizes. The wind turbine blade passes through the gap between the two support seats 2 and the pressing plate 15, allowing it to land on top of the second soft pad 17. Then, the bolt 1 is rotated, causing the pressing plate 15 to descend. As the pressing plate 15 descends... The first soft pad 16 will descend and press against the wind turbine blade, minimizing damage to the blade. The rubber pad 6 can reduce vibration during motor 13 operation. After the wind turbine blade is fixed, the electric push rod 9 is activated, which drives the second support plate 7 to rotate along the connection with the support rod 11, thereby adjusting the angle of the wind turbine blade. After the angle of the wind turbine blade is adjusted, the blade is in a state where one side is higher than the other. At this time, another device is placed on one side of the current lifting device, so that one side of the wind turbine blade is below the current blade, thus saving lateral placement space. Finally, the current wind turbine blade lifting devices are pulled away from the centralized placement area.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
