The height of the clamping plate for installing the wind blades in the placement rack is fixed, and the placement height of the wind turbine blades cannot be adjusted as needed; 2.

Under the action of the first telescopic rod 210 pulling the rocker 29, the position of the clamp block 26 can be adjusted once, and under the action of the second telescopic rod, the position of the clamp block 26 relative to the rocker 29 can be further adjusted. Under the action of the clamp block 26 and the clamp head 213, the fan blades can be clamped; and the position of the clamp block 26 is adjusted twice to adapt to different clamping requirements.

The lower end of the cone block three 414 is fixed with a slider two 415, and the slider two 415 slides in the slide groove 416 in the base 411. The right end of the cone block three 414 is connected to the cone block four 417, and the cone block four 417 slides through the right wall 420 of the first groove.

[0067] The second groove 413 is located in the base 411 , and the upper end of the base 411 is open.

[0068] Among them, Figure 5 As shown, the conical blocks 1 45 on the left and right sides are symmetrical, and the left side of the conical block 1 45 on the left is provided with a conical surface 1 which is higher on the left and lower on the right; the conical blocks 2 49 on the left and right sides are symmetrical, and the left side of the conical block 2 49 on the left is provided with a conical surface 2 which is higher on the left and lower on the right; the conical blocks 4 417 on the left and right sides are symmetrical, and the conical block 4 417 on the left is higher on the left and lower on the right.

[0069] The buffer member 412 may be a spring or a spring rod or an air bag.

[0070] The working principle and beneficial effects of the above technical solution are as follows: in the present invention, when the clamping device 2 has clamped the fan blade 3, the bottom plate 12 will be subjected to downward pressure, the first spring 41 begins to compress downward, and the first vertical rod 44 connected to the bottom plate 12 drives the conical block 1 45 to start moving downward. When the bottom plate 12 presses the horizontal plate 42 to a certain extent, the horizontal plate 42 also begins to compress the second spring 47, and the fixed plate 43 fixed on the lower side of the horizontal plate 42 begins to move downward, and the buffer 412 connected to the fixed plate 43 through the third vertical rod 410 also begins to move downward. When the two conical blocks 1 45 at the lower end of the first vertical rod 44 contact the conical blocks 3 414 at both ends of the first groove 419, the conical block 1 45 begins to press the conical block 3 414. At this time, the conical block 3 414 on the left side begins to move to the left, and the conical block 3 414 on the right side begins to move to the right. The third spring 418 The third spring 418 also gradually extends, and the fourth conical block 417 connected to the third conical block 414 begins to move in the direction of the third conical block 414. The third conical block 414 and the third spring 418 buffer the support as a whole composed of the transverse plate 42 and the buffer 412, ensuring the stable descent of the support as a whole. When the buffer 412 completely enters the second groove 413, the bottom plate 12 will not continue to be pressed downward. At this time, the first spring 41, the second spring 47 and the third spring 418 will have an elastic force. The first spring 41 gives an upward elastic force to the bottom plate 12, and the second spring 47 gives an upward elastic force to the transverse plate 42. The third spring 418 will pull the third conical block 414 inward. At this time, the fourth conical block 417 moves inward with the movement of the third conical block 414, and the fourth conical block 417 will block the upward movement of the second conical block 49. At this time, the buffer 412 will not move, thereby achieving a stable buffering effect. The conical block 1 45 and the conical block 3 414 can support the sides of the above-mentioned support as a whole, while the buffer member 412 supports the middle part of the support as a whole, thereby ensuring the support stability of the support as a whole.
