AI Technical Summary
Wind turbine blades are prone to deformation during transportation due to their own weight, and existing technologies are insufficient to effectively support the middle section, affecting the quality of the blades.
A wind turbine blade clamping device was designed, comprising a rotatable circular wheel frame and a clamping plate, equipped with limit rollers and hydraulic cylinder clamping blocks, to achieve lifting and angle adjustment of the blade in the middle, and to adapt to clamping and fixing blades of different sizes.
This effectively avoids deformation due to the blade's own weight, ensuring stability and accurate positioning during transportation, and preventing angular deviation and swaying.

Description
Technical Field
[0001] This utility model relates to the field of transportation technology, specifically a wind turbine blade clamping device. Background Technology
[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy. Due to their large size, wind turbine blades are difficult to transport. They are made of composite materials, carbon fiber, and other materials. Currently, most transport supports fix the root and top of the wind turbine blades before transporting them. However, due to their long length and weight, the middle blade section is prone to deformation, affecting the quality of the blades. Therefore, a clamping and support device for the middle part of the wind turbine blade is needed. Utility Model Content
[0003] The purpose of this invention is to provide a wind turbine blade clamping device to solve the problems existing in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade clamping device, comprising a base 1, characterized in that: a rotatable circular wheel frame 9 is provided on the base 1, and symmetrical rollers 3 are provided below the circular wheel frame 9. The rollers 3 are supported on the base 1 by bearing seats 2. Guide grooves 8 are provided on both the front and rear sides of the circular wheel frame 9, and limiting rollers 17 are provided in the guide grooves 8 and are mounted on a bracket 4 through a support shaft 16; a symmetrical clamping plate 13 is provided in the middle of the circular wheel frame 9, and the lower part of the clamping plate 13 is hinged to the circular wheel frame 9 through a rotating shaft 15, and the upper part is hinged to an adjusting rod 12 through a bidirectional hinge block 11 and a hinge shaft 10. The adjusting rod 12 is threadedly connected to the circular wheel frame 9; a V-shaped support seat 5 is provided below the center of the circular wheel frame 9.
[0005] Furthermore, there are four limiting rollers 17 in total, divided into two symmetrical groups. The limiting rollers 17 in the same group are symmetrically arranged in the guide grooves 8 at the front and rear ends of the circular wheel frame 9, and the limiting rollers 17 are located at the center line of the circular wheel frame 9.
[0006] Furthermore, each of the brackets 4 is equipped with a hydraulic cylinder 6 at its top, and the output end of the hydraulic cylinder 6 is equipped with a clamping block 7.
[0007] Furthermore, the clamping plate 13 is provided with a contoured arc surface 14 that has the same curvature as the middle part of the wind turbine blade.
[0008] This utility model has the following advantages: First, it can support the middle part of the wind turbine blade, preventing deformation caused by the blade's own weight; second, the angle is adjustable, preventing the wind turbine blade from being too long or having an angle deviation that would prevent it from being clamped; third, it is equipped with an adjustment mechanism and a clamping mechanism, which can clamp the wind turbine blade according to its size and prevent it from shaking during transportation.

[0013] A wind turbine blade clamping device includes a base 1, on which a rotatable circular wheel frame 9 is provided. Symmetrical rollers 3 are provided below the circular wheel frame 9. The rollers 3 are supported on the base 1 by bearing seats 2. The circular wheel frame 9 has guide grooves 8 on both the front and rear sides, and limiting rollers 17 are provided in the guide grooves 8 and are mounted on a bracket 4 through a support shaft 16. There are four limiting rollers 17 in total, divided into two symmetrical groups. The limiting rollers 17 in the same group are symmetrically arranged in the guide grooves 8 at the front and rear ends of the circular wheel frame 9, and the limiting rollers 17 are located at the center line of the circular wheel frame 9. In this way, the circular wheel frame 9 can rotate to adjust the angle by rotating the rollers 3, and the limiting rollers 17 on the front, rear and sides restrict the running direction and prevent the circular wheel frame 9 from swaying back and forth or left and right.
[0014] The circular wheel frame 9 has symmetrical clamping plates 13 in the middle. The lower part of the clamping plates 13 is hinged to the circular wheel frame 9 through a rotating shaft 15, and the upper part is hinged to the adjusting rod 12 through a two-way hinge block 11 and a hinge shaft 10. The adjusting rod 12 is connected to the circular wheel frame 9 by a thread. The clamping plates 13 have a contoured arc surface 14 with the same curvature as the middle part of the wind turbine blade, so that it can be adjusted and locked according to the size of the wind turbine blade.
[0015] To improve support capacity, a V-shaped support seat 5 is provided below the center of the circular wheel frame 9. Finally, the clamping plate 13 is adjusted to fit the wind turbine blade to clamp the blade.
[0016] Each bracket 4 is equipped with a hydraulic cylinder 6 at its top, and the output end of the hydraulic cylinder 6 is equipped with a clamping block 7. When the angle is fixed, the hydraulic cylinder 6 pushes the clamping block 7 to clamp the circular wheel frame 9.
