Description

Technical Field

[0001] The invention relates to the technical field of brackets, and in particular to a seesaw type wind turbine blade storage rack. Background Art

[0002] Wind turbines convert the kinetic energy of wind into rotational mechanical energy, thereby driving the generator to generate electricity. The main component that transmits wind power is the wind turbine blade. Wind turbine blades are flexible blades, and their size is related to the power generation of wind turbines. In order to obtain higher power, some wind turbine blades need to be as long as 75 meters and weigh up to 50 tons. In addition, wind turbine blades have irregular arcs, are brittle, soft, and easily damaged, which puts high demands on the storage racks.

[0003] The main structure of a wind turbine blade has a certain curvature, so it is often necessary to use a flexible sling to adapt to the curved structure. For this reason, our company has applied for an adjustable wind turbine blade tip storage rack (application number: CN201620488252.8), which uses multiple parallel reversing rods to wrap the end of the sling. However, this structure limits the deformation flexibility of the sling, resulting in a possible failure to have good contact with the tip of the wind turbine blade.

[0004] Therefore, it is necessary to provide a new structure to allow the wind turbine blade storage rack to better fit the tip of the wind turbine blade. Summary of the invention

[0005] The main purpose of the present invention is to provide a seesaw-type wind turbine blade storage rack, which can automatically adapt to the tip support position of the wind turbine blade.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: a seesaw type wind turbine blade storage rack, comprising a frame body and a pair of long slings and a pair of short slings suspended from the frame body, wherein a first long support rod, a second long support rod, a first short support rod and a second short support rod are arranged in parallel on both sides of the frame body, the first long support rod and the first short support rod are located on the same side and the first long support rod is higher than the first short support rod, the second long support rod and the second short support rod are located on the same side and the second long support rod is lower than the second short support rod; a first seesaw is pivotally connected to the frame body between the first long support rod and the first short support rod, one end of the two long slings are fixed to the second long support rod, and the other end crosses the first long support rod and is respectively fixed to both sides of the first seesaw; a second seesaw is pivotally connected to the frame body between the second long support rod and the second short support rod, one end of the two short slings are fixed to the first short support rod, and the other end crosses the second short support rod and is respectively fixed to both sides of the second seesaw.

[0007] Specifically, the frame includes two pairs of I-shaped support columns.

[0008] Furthermore, a foot is provided at the bottom of each support column.

[0009] Furthermore, a lifting hook is provided above each support column.

[0010] Specifically, a pair of forklift pipes are also provided below the frame body.

[0011] The beneficial effects of adopting the above technical solutions are as follows:

[0012] This storage rack can adapt to the complex structure of the tip of the wind turbine blade, ensure that the sling fits the surface of the blade tip at any time, and guarantee the stability of storage. Description of the Drawings

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] Embodiment:

[0021] As Figure 1 and Figure 2As shown in the figure, a seesaw - type wind power blade storage rack of the present invention includes a frame body 1, a pair of long suspension straps 2a, 2b and a pair of short suspension straps 3a, 3b hanging on the frame body 1. On both sides of the frame body 1, a first long support rod 11a, a second long support rod 11b, a first short support rod 12a and a second short support rod 12b are arranged in parallel. The first long support rod 11a and the first short support rod 12a are on the same side and the first long support rod 11a is higher than the first short support rod 12a. The second long support rod 11b and the second short support rod 12b are on the same side and the second long support rod 11b is lower than the second short support rod 12b. A first seesaw 13a is pivotally connected to the frame body 1 between the first long support rod 11a and the first short support rod 12a. One ends of the two long suspension straps 2a, 2b are both fixed to the second long support rod 11b, and the other ends cross over the first long support rod 11a and are respectively fixed to both sides of the first seesaw 13a. A second seesaw 13b is pivotally connected to the frame body 1 between the second long support rod 11b and the second short support rod 12b. One ends of the two short suspension straps 3a, 3b are both fixed to the first short support rod 12a, and the other ends cross over the second short support rod 12b and are respectively fixed to both sides of the second seesaw 13b. The long suspension straps 2a, 2b and the short suspension straps 3a, 3b can provide an obliquely upward supporting force from two directions, so that the wind power blade only contacts with the flexible suspension straps, preventing it from hitting the frame body 1. The first seesaw 13a can automatically adjust the front - back deflection of the two long suspension straps 2a, 2b after being loaded with the wind power blade. Specifically, if the long suspension strap 2a is tight and the long suspension strap 2b is loose, the first seesaw 13a will make one side of the long suspension strap 2a drop, and the corresponding side of the long suspension strap 2b will rise, finally making the two long suspension straps 2a, 2b in a matching tightness state; conversely, it will make one side of the long suspension strap 2a rise, and the corresponding side of the long suspension strap 2b will drop, still making the two long suspension straps 2a, 2b in a matching tightness state. Similarly, the second seesaw 13b can automatically adjust the front - back deflection of the two short suspension straps 3a, 3b. Therefore, this storage rack can adapt to the complex structure of the wind power blade tip, ensuring that the suspension straps fit the tip surface at any time and guaranteeing the stability of storage.

[0022] As Figure 1 and Figure 2 shown in the figure, the frame body 1 includes two pairs of I - shaped support columns 14. Such support columns 14 have a greater load - bearing capacity and can prevent the storage rack from collapsing when loaded.

[0023] As Figure 1 and Figure 2 shown in the figure, a foot pad 141 is provided at the bottom of each support column 14. The foot pad 141 can increase the contact area of the frame body 1 with the ground, reduce the pressure, so as to prevent the ground from being damaged when the storage rack is loaded.

[0024] As Figure 1 shown in the figure, a hook 142 is provided above each support column 14. The hook 142 enables the entire frame body 1 to be lifted and transported.

[0025] As Figure 1 shown, a pair of forklift pipes 15 are also provided below the frame body 1. The frame body 1 enables a forklift to transport using the forklift pipes 15.

[0026] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
