Description

Technical Field

[0001] This utility model relates to the field of wind power equipment transportation technology, specifically a stacked support for containerized transportation of wind turbine blades. Background Technology

[0002] Wind power generation is the process of converting wind energy into electrical energy. It uses wind turbine blades to capture wind energy, convert it into mechanical energy, and then uses a generator to convert the mechanical energy into electrical energy. After the generator blades are manufactured, they need to be supported and positioned using brackets during storage and transportation.

[0003] A search revealed that the announcement number CN217100943U, entitled "A Stacked Support for Containerized Transportation of Wind Turbine Blades," includes a first frame. Research and analysis showed that while placing the blade body on the first and third frames using a crane simplifies operation, controlling the extension of a pneumatic cylinder to clamp the blade body ensures stable clamping, and attaching the second frame to the top of the first frame with connecting bolts facilitates stacked installation, the following drawbacks still exist to some extent.

[0004] For example, the blade head is not securely fixed. The above-mentioned bracket fixes the blade head by tightening the adjusting rod and pushing the second arc plate. Due to the vibration generated by the vehicle during transportation, the adjusting rod can easily rotate, causing the blade head to loosen and impact the bracket. Frequent impacts between the upper and lower blade heads on the bracket can cause it to tilt, posing a great safety risk. At the same time, a pneumatic cylinder is required to fix the blade tail, which requires an external pneumatic device for driving, increasing the manufacturing cost. In order to solve the above technical problems, we have designed a stacked bracket for containerized transportation of wind turbine blades. Utility Model Content

[0005] The purpose of this utility model is to provide a laminated support for containerized transport of wind turbine blades, which has the advantages of more secure fixing of the blade head, avoiding impact on the support due to loosening, improving transportation safety, more flexible limiting operation of the blade tail, and reducing manufacturing costs. It solves the problems of insufficient fixing of the blade head, easy loosening and impact on the support causing tilting, low transportation safety, and high production cost of the limiting structure at the blade tail, which increases subsequent maintenance and replacement costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacked support for transporting wind turbine blades in a container, comprising a base frame, a top frame inserted into the top of the base frame, arc-shaped plates welded to the inner cavities of both the top frame and the base frame, a limit baffle welded to the outer side of the arc-shaped plates, a blade body clamped between the upper and lower arc-shaped plates, a mounting flange welded to the front side of the blade body, positioning pins inserted into the left and right sides of the rear top of the base frame, positioning mechanisms welded to the left and right sides of the front top of the base frame, support vertical plates provided on the rear sides of the left and right sides of the blade body, a limit screw threaded through the inner side of the support vertical plate, a fixing frame movably connected to the inner side of the limit screw, clamping screws threaded through the top and bottom of the fixing frame, and a limit clamping plate movably connected to the inner side of the clamping screw.

[0007] Preferably, the positioning mechanism includes a fixed shell, with a positioning insert plate slidably connected to the top and bottom of the inner cavity of the fixed shell, a positioning spring installed between the upper and lower positioning insert plates, and the outer side of the positioning insert plate extending to the outer side of the positioning pin.

[0008] Preferably, the outer side of the fixed shell is provided with a sliding opening, and the outer side of the positioning insert plate passes through the sliding opening and is fixedly connected to a push plate.

[0009] Preferably, mounting plates are welded to the bottom of the left and right sides of the base frame and the top of the left and right sides of the top frame, and a positioning base plate is welded to the bottom of the outer side of the support vertical plate.

[0010] Preferably, a positioning bolt is movably installed through the outer side of the limiting baffle, and the inner side of the positioning bolt is threadedly connected to the mounting flange.

[0011] Preferably, mounting slots are provided on both the left and right sides of the top of the base frame, mounting plates are welded on both the left and right sides of the bottom of the top frame, and limit pads are welded on both the left and right sides of the front of the base frame.

[0012] Preferably, guide slides are welded to the top and bottom of the outer side of the fixing frame, the outer side of the guide slides extends to the outer side of the supporting vertical plate, and a shock-absorbing pad is glued to the inner cavity of the fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The head of the blade body is placed on the arc plate inside the base frame. The top frame is inserted into the mounting slot and a positioning pin is inserted for positioning. The arc plate inside the top frame limits the upper part of the blade body head. Positioning bolts are used to pass through the limiting baffle and screw into the mounting flange for positioning. This double positioning makes the head more secure, avoids loosening and impacting the bracket during transportation, and improves transportation safety.

[0015] 2. Rotate the limiting screw clockwise to push the fixing frame to limit the front and rear sides of the blade body tail. Rotate the clamping screws on the upper and lower sides clockwise to push the limiting clamps to limit the upper and lower sides of the blade tail. This makes the structure for fixing the blade tail simpler, effectively reducing manufacturing costs and subsequent maintenance and replacement costs. Attached Figure Description

[0022] Please see Figures 1-5A stacked support for transporting wind turbine blades includes a base frame 1, a top frame 2 inserted into the top of the base frame 1, arc-shaped plates 6 welded to the inner cavities of both the top frame 2 and the base frame 1, and limit baffles 4 welded to the outer sides of the arc-shaped plates 6. A blade body 7 is held between the upper and lower arc-shaped plates 6. A mounting flange 3 is welded to the front side of the blade body 7. Positioning pins 17 are inserted into the left and right sides of the top rear side of the base frame 1. The top and bottom front sides of the positioning pins 17 have insertion holes to facilitate the insertion of the positioning plates 2 on the upper and lower sides. 1. Insert into the interior for positioning. Positioning mechanisms 5 are welded to the left and right sides of the top front side of the base frame 1. Supporting vertical plates 8 are provided on the rear sides of the left and right sides of the blade body 7. The inner side of the supporting vertical plate 8 is threadedly connected to a limiting screw 10. The inner side of the limiting screw 10 is movably connected to a fixing frame 9. The top and bottom of the fixing frame 9 are threadedly connected to clamping screws 25. A rotating plate is fixedly connected to the outer side of the clamping screw 25 and the limiting screw 10. The inner side of the clamping screw 25 is movably connected to a limiting clamping plate 24.

[0023] Please see Figure 3 The positioning mechanism 5 includes a fixed shell 19. The top and bottom of the inner cavity of the fixed shell 19 are slidably connected with positioning inserts 21. A positioning spring 20 is installed between the upper and lower positioning inserts 21. The outer side of the positioning inserts 21 extends to the outer side of the positioning pin 17. By setting the positioning mechanism 5, the positioning spring 20 can release the elastic force to push the upper and lower positioning inserts 21 into the top and bottom of the positioning pin 17, which facilitates the disassembly and assembly of the positioning pin 17.

[0024] Please see Figure 3 A sliding opening is provided on the outer side of the fixed shell 19, and a push plate 18 is fixedly connected to the outer side of the positioning plate 21 through the sliding opening. By setting the push plate 18, the positioning plate 21 can be easily pushed up and down.

[0025] Please see Figure 1 Mounting plates 13 are welded to the bottom of the left and right sides of the base frame 1 and the top of the left and right sides of the top frame 2. By setting the mounting plates 13, the base frame 1 can be easily installed and positioned. At the same time, bolts can be used to fix the upper and lower mounting plates 13 during the stacking process so that the top frame 2 and the base frame 1 can be fixedly connected to complete the stacking. A positioning base plate 12 is welded to the bottom of the outer side of the support vertical plate 8. By setting the positioning base plate 12, bolts can be easily passed through to fix the support vertical plate 8 to the carriage.

[0026] Please see Figure 2 A positioning bolt 16 is movably installed through the outer side of the limiting baffle 4, and the inner side of the positioning bolt 16 is threadedly connected to the mounting flange 3.

[0027] Please see Figure 2Mounting slots 15 are provided on both the left and right sides of the top of the base frame 1, and mounting plates 14 are welded to both the left and right sides of the bottom of the top frame 2. Limiting pads 22 are welded to both the left and right sides of the front of the base frame 1. By setting the limiting pads 22, the outer end of the positioning plate 21 can be supported and limited to prevent loosening.

[0028] Please see Figure 4 The top and bottom of the outer side of the fixed frame 9 are welded with guide slide plates 11. By setting the guide slide plates 11, the fixed frame 9 can be limited and guided to make its movement more stable. The outer side of the guide slide plates 11 extends to the outer side of the supporting vertical plate 8. The inner cavity of the fixed frame 9 is glued with a shock-absorbing pad 23. The shock-absorbing pad 23 and the limiting clamp 24 are both made of polyurethane rubber, which reduces stress concentration on the blade surface and has the function of shock absorption, reducing the vibration frequency.

[0029] In use, the base frame 1 and the positioning base plate 12 are bolted to the cargo compartment of the transport vehicle, and the installation distance between the positioning base plate 12 and the base frame 1 is measured. Then, the blade body 7 is lifted by hoisting equipment, and the head of the blade body 7 is placed on the arc plate 6 inside the base frame 1. The tail of the blade body 7 is inserted between the support vertical plates 8 on the front and rear sides. Then, the mounting plates 14 on both sides of the bottom of the top frame 2 are inserted into the mounting slots 15, and the positioning pins 17 are inserted to position the mounting plates 14. In this way, the arc plate 6 inside the top frame 2 is fitted onto the upper half of the head of the blade body 7. Then, the positioning bolts 16 are used to pass through the limit. Positioning baffle 4 is screwed into the threaded hole on mounting flange 3 for positioning. This double positioning of the blade body 7 head makes it more secure, preventing loosening and impact on the support during transportation and improving transportation safety. The front and rear limit screws 10 are rotated clockwise to push the front and rear fixing brackets 9 to fit onto the front and rear sides of the blade body 7 tail for positioning. Then, the upper and lower clamping screws 25 are rotated clockwise to push the limit clamps 24 to limit the upper and lower sides of the blade tail. This makes the structure for fixing the blade tail simpler, effectively reducing manufacturing costs and subsequent maintenance and replacement costs.

[0030] In summary, this stacked support for transporting wind turbine blades, through the coordinated use of the base frame 1, top frame 2, limiting baffle 4, positioning mechanism 5, arc plate 6, supporting vertical plate 8, fixing frame 9, limiting screw 10, positioning bolt 16, and positioning pin 17, solves the problems of insufficient fixation of the blade head, easy loosening and impact on the support causing tilting, low transportation safety, and high production cost of the limiting structure at the blade tail, which increases subsequent maintenance and replacement costs.
