[0024] 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.

[0025] Reference Figure 1-2 and Figure 4-5This utility model provides an embodiment of a lifting device for transporting wind turbine blades, including a stabilizing base mechanism 1 and a lifting mechanism 2. The stabilizing base mechanism 1 includes a stabilizing base body 101. A first cylinder 102 is fixedly installed at the four outer corners of the lower end of the stabilizing base body 101. Anti-slip plates 103 are fixedly installed at the lower ends of multiple first cylinders 102. Fixing plates 104 are fixedly installed at the upper outer positions of multiple anti-slip plates 103. Threaded rods 105 are threaded into the middle of multiple fixing plates 104. Ground cone plates 106 are slidably installed at the lower outer positions of multiple anti-slip plates 103. A third cylinder 111 is fixedly installed at the front end of the stabilizing base body 101. A mounting plate 112 is fixedly installed at the front end of the 11th unit. A first servo motor 113 is fixedly installed at the lower front side of the mounting plate 112. A first gear 114 is fixedly installed at the output end of the first servo motor 113. A second gear 115 is rotatably installed at the upper rear side of the mounting plate 112 via a rotating shaft. A connecting column 116 is fixedly installed at the upper end of the second gear 115. A second cylinder 108 is fixedly installed at the middle of both sides of the stabilizer body 101. A shock-absorbing pad 109 is fixedly installed at the lower end of the two second cylinders 108. A moving wheel 107 is fixedly installed at the four corners of the lower middle part of the stabilizer body 101. A battery box 110 is fixedly installed at the upper rear side of the stabilizer body 101.

[0026] Specifically, in the stabilizing base mechanism 1, the function of cylinder 102 is to adjust the height of the anti-slip plate 103 so that it is in close contact with the ground, thereby enhancing the overall stability of the equipment. The fixing plate 104 on the anti-slip plate 103, in conjunction with the threaded rod 105, can further push the ground cone plate 106 down and insert it into the ground when the threaded rod 105 rotates, providing additional anchoring force. Cylinder 111 can push the mounting plate 112 forward or backward. Servo motor 113 drives gear 114 to rotate, and through meshing with gear 115, the connecting column 116 is rotated. The connecting column 116 is used to connect the lifting mechanism 2, which facilitates the adjustment of the rotation angle of the lifting mechanism 2. Cylinder 108 can adjust the height of the shock-absorbing pad 109 according to actual needs. The shock-absorbing pad 109 can play a buffering and stabilizing role when the equipment is placed on uneven ground. The moving wheel 107 facilitates the movement of the equipment between different work sites. The battery box 110 provides power support for the entire stabilizing base mechanism 1 and the lifting mechanism 2.

[0027] Reference Figure 3-4The lifting mechanism 2 includes a mounting base 201, a mounting box 202 fixedly mounted on the upper end of the mounting base 201, a second servo motor 203 fixedly mounted on the upper end of the mounting box 202, a threaded post 204 fixedly mounted on the output end of the second servo motor 203, a threaded box 205 threadedly fitted on the outer surface of the threaded post 204, an extension plate 206 fixedly mounted on the front end of the threaded box 205, a first mounting bracket 207 fixedly mounted on the front end of the extension plate 206, and second telescopic rods 2 fixedly mounted on both sides of the upper end of the first mounting bracket 207. 10. Two No. 2 telescopic rods 210 are fixedly mounted with No. 2 mounting brackets 211 at their upper ends. No. 1 telescopic rods 208 are slidably mounted on both sides of No. 1 mounting bracket 207. Support pads 209 are fixedly mounted on the front ends of the two No. 1 telescopic rods 208 and the middle front end of No. 1 mounting bracket 207 via telescopic rods. No. 3 telescopic rods 212 are slidably mounted on both sides of No. 2 mounting bracket 211. Fixed hooks 213 are threadedly mounted on the lower front end of the two No. 3 telescopic rods 212 and the lower middle front end of No. 2 mounting bracket 211.

[0028] Specifically, in the lifting mechanism 2, the mounting base 201 is used to fix the entire lifting mechanism 2 in a suitable position on the stabilizing base mechanism 1. After the second servo motor 203 is started, it drives the threaded column 204 to rotate, so that the threaded box 205 can move up and down along the axial direction of the threaded column 204, thereby adjusting the height of the extension plate 206. A limit block is set at the rear end of the threaded box 205, which slides on the inner wall of the rear side of the mounting box 202. The first mounting bracket 207 at the front end of the extension plate 206 is used to install and support the first telescopic rod 208 and the second telescopic rod 210. The first telescopic rod 208 can be adjusted back and forth according to the length of the wind turbine blade. The front end of the first mounting frame 207 and the support pad 209 at the front center of the first mounting frame 207 can support and protect the blades during transportation, preventing damage to the blade surface. The second telescopic rod 210 is used to adjust the height of the second mounting frame 211 to accommodate blades of different sizes. The third telescopic rod 212 on both sides of the second mounting frame 211 can extend and retract left and right. The fixing hook 213 on the lower front end and the lower middle front end of the second mounting frame 211 can firmly hook the wind turbine blades. The upper end of the wind turbine blades is fixed by the fixing hook 213 in conjunction with the lifting rope, and the lower end is supported by the support pad 209 to ensure the stability of the blades during transportation.

[0029] Working principle: When using this wind turbine blade transport lifting equipment, first move the equipment to the designated position, and ensure the stability of the equipment through the stabilizing seat mechanism 1. Start the first cylinder 102 to adjust the height of the anti-slip plate 103 so that it is in close contact with the ground. At the same time, rotate the threaded rod 105 to push the ground cone plate 106 down to insert into the ground and enhance the anchoring force. According to the flatness of the ground, start the second cylinder 108 to adjust the height of the shock-absorbing pad 109 to play a buffering and stabilizing role. If it is necessary to adjust the rotation angle of the lifting mechanism 2, start the third cylinder 111 to push the mounting plate 112 forward or backward, and then start the first servo motor 113 to drive the first gear 114 to rotate. Through the meshing with the second gear 115, the connecting column 116 is rotated, thereby adjusting the angle of the lifting mechanism 2.

[0030] Next, the lifting mechanism 2 is operated to lift the blade. The second servo motor 203 is started, which drives the threaded column 204 to rotate, so that the threaded box 205 moves along the axial direction of the threaded column 204. The height of the extension plate 206 is adjusted. According to the length of the wind turbine blade, the first telescopic rod 208 is extended and retracted. The front end of the first telescopic rod and the support pad 209 at the middle of the front end of the first mounting frame 207 provide support and protection for the lower end of the blade. At the same time, the height of the second mounting frame 211 is adjusted by the second telescopic rod 210, and then the third telescopic rod 212 is extended and retracted. The fixed hook 213 on the lower side of its front end and the lower side of the middle of the front end of the second mounting frame 211 is used to hook the upper end of the blade and fix it with the lifting rope to ensure the stability of the blade during the lifting process. Throughout the process, the battery box 110 provides power support for the stabilizing seat mechanism 1 and the lifting mechanism 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
