A second transport box is attached to the top of the first transport box. First fixing plates are fixedly connected to both ends of the second transport box. Threaded sleeves are fixedly connected to both first fixing plates. Threaded posts are threadedly connected to both threaded sleeves. Second fixing plates are fixedly connected to both ends of the first transport box. Threaded caps are fixedly connected to the top of both second fixing plates.

[0003] This patent meets the requirements for transport supports needed for transporting wind turbine blades. However, the transport boxes of this support are only fixed together by threaded posts. Stacking multiple layers can easily cause relative displacement due to lateral forces, posing a risk of tipping over. Furthermore, the threaded posts only bear force on both sides, and long-term load-bearing may cause the transport boxes to tilt.

[0004] Therefore, a wind turbine blade transport support is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wind turbine blade transport support, which aims to improve the problem of insufficient stacking stability of transport boxes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wind turbine blade transport support, including a base, a first transport box fixedly connected to the base, a second transport box fixedly connected to the first transport box, and positioning grooves provided on the top left and right sides of the first transport box, and a positioning column fixedly connected to the bottom of the second transport box.

A conical locking end is integrally fixedly connected to the top of the cylindrical positioning end, and an elastic steel ball is rotatably connected inside the conical locking end.

[0008] Preferably, the positioning groove cooperates with the positioning post.

[0009] Preferably, the spacing between the positioning grooves on the right side of the first transport box is greater than the spacing between the positioning grooves on the left side of the first transport box.

[0010] Preferably, both the first and second transport boxes are fixedly connected to partitions, and both the first and second transport boxes are provided with placement slots through the partitions. An electric push rod is fixedly connected to the top of the placement slot, and a first clamping plate is fixedly connected to the bottom of the placement slot; a second clamping plate is fixedly connected to the output end of the electric push rod.

[0011] Preferably, the left and right ends of the second transport box are fixedly connected to a first fixing plate, the first fixing plate is internally threaded with a threaded post, and the left and right ends of the first transport box are fixedly connected to a second fixing plate, the threaded post being threadedly connected to the second fixing plate.

[0012] Preferably, the contact surfaces between the first and second clamping plates and the wind turbine blades are both arc-shaped, and a polyurethane buffer layer is fixedly connected to the arc-shaped contact surfaces of the first and second clamping plates.

[0013] Preferably, the positioning post is a 40Cr alloy steel positioning post, and the surface of the positioning post is nitrided; the elastic steel ball is a bearing steel elastic steel ball.

[0014] Preferably, a control terminal is also fixedly connected to the base, and the control terminal is electrically connected to the electric push rod via a wire.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the multi-segment positioning column improves the docking accuracy of the upper and lower transport boxes by layered positioning, controls the installation deviation within a very small range, and ensures that the wind turbine blades remain stable during transportation and will not shake due to installation deviation; the different spacing of the positioning grooves on both sides of the transport box prevents positioning deviation caused by reverse installation.

Detailed Implementation

[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 Figures 1 to 4 One embodiment of this utility model is a wind turbine blade transport support, which includes a base 1, a first transport box 2 fixedly connected to the top of the base, a second transport box 3 fixedly connected to the top of the first transport box 2 by a threaded post 16, and a third and fourth transport box can be stacked on the second transport box 3 as needed.

[0026] Except for the bottommost first transport box 2, which has second fixing plates 17 fixedly connected to its left and right sides near the top, and the topmost transport box, which has first fixing plates 15 fixedly connected to its left and right sides near the bottom, the middle transport boxes have first fixing plates 15 and second fixing plates 17 fixedly connected to their left and right sides. The first fixing plate 15 of the upper transport box and the second fixing plate 17 of the lower transport box are fixedly connected by threaded posts 16, and the top of the threaded posts 16 can be fixedly connected to a rotating ring for easy rotation.

[0027] The bottom of the upper transport box of the second type (3) is fixedly connected to a positioning post 5, while the top of the lower transport box of the first type (2) has a positioning groove 4 that matches the positioning post 5. The positioning post 5 includes a tapered guide end 6, the bottom of which is designed to be spherical, a shape that helps reduce resistance during docking. The top of the tapered guide end 6 is connected to a cylindrical positioning end 7 in an integral fixed connection, ensuring accurate positioning between transport boxes. The top of the cylindrical positioning end 7 is also connected to a tapered locking end 8 in an integral fixed connection, and the interior of the tapered locking end 8 is rotatably connected to an elastic steel ball 9, which enhances the stability of the connection between the positioning post 5 and the positioning groove 4.

[0028] In terms of material selection, the positioning post 5 is made of 40Cr alloy steel, and its surface is nitrided, which greatly improves the wear resistance and service life of the positioning post 5; the elastic steel ball 9 is a bearing steel elastic steel ball 9, which ensures that it has good elasticity and strength.

[0029] The spacing between the positioning grooves 4 on the right side of the first transport box 2 is greater than the spacing between the positioning grooves 4 on the left side. This design ensures that there is only one installation direction between the transport boxes, avoiding positioning deviations caused by reverse installation.

[0030] Inside both the first transport box 2 and the second transport box 3, partitions 10 are fixedly connected, dividing the interior of the transport box into multiple placement slots 11. These slots 11 are specifically designed for placing wind turbine blades. Each placement slot 11 has an electric push rod 12 fixedly connected to its top and a first clamping plate 13 fixedly connected to its bottom. The output end of the electric push rod 12 is fixedly connected to a second clamping plate 14. By extending and retracting the electric push rod 12, the second clamping plate 14 can be moved up and down, thus cooperating with the first clamping plate 13 to clamp the wind turbine blade. To accommodate the wind turbine blade tip shape, the contact surfaces of the first clamping plate 13 and the second clamping plate 14 with the wind turbine blade are designed to be arc-shaped, and a polyurethane buffer layer 18 is fixedly connected to each arc-shaped contact surface. This ensures clamping stability and prevents damage to the wind turbine blade.

[0031] To ensure clamping stability, a support plate can be fixedly installed on the first clamping plate 13, and a groove adapted to the support plate is opened on the second clamping plate 14. Slider blocks can be fixedly installed on both sides of the support plate, and a spring is fixedly installed on the top of the slider, with the top of the spring fixedly installed in the groove. When the electric push rod 12 pushes the first clamping plate 13 down, the spring can prevent the device from over-clamping.

[0032] A control terminal 19 is also fixedly connected to the base 1. The control terminal 19 is electrically connected to the electric push rod 12 via a wire. The operator can control the movement of the electric push rod 12 through the control terminal 19 to facilitate the loading and unloading of wind turbine blades. Rollers can also be installed on the bottom of the base 1 to facilitate short-distance transportation of the device.

[0033] Working principle: In terms of stacking and fixing transport boxes, the first transport box 2 on the base 1 serves as a base, and upper transport boxes can be stacked sequentially via threaded posts 16. The first fixing plate 15 of the upper transport box is connected to the second fixing plate 17 of the lower layer via threaded posts 16. At the same time, the positioning post 5 at the bottom of the upper transport box and the positioning groove 4 at the top of the lower layer cooperate to achieve precise docking. The conical guide end 6 of the positioning post 5 reduces docking resistance, the cylindrical positioning end 7 ensures accurate positioning, and the elastic steel ball 9 in the conical locking end 8 enhances the connection stability; moreover, the spacing of the left and right positioning grooves 4 of the first transport box 2 is different, ensuring that the transport box can only be installed in one direction, avoiding positioning deviation caused by reverse installation.

[0034] In terms of wind turbine blade clamping protection, the electric push rod 12 is extended and retracted by the control terminal 19, thereby driving the second clamping plate 14 to move up and down, cooperating with the first clamping plate 13 to clamp the wind turbine blade. The contact surface between the clamping plate and the wind turbine blade is designed to be arc-shaped to match the blade tip shape; the polyurethane buffer layer 18 on the arc-shaped surface can prevent damage to the blade during clamping.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
