[0001] This invention relates to the field of transfer equipment technology, specifically to a positioning bracket and a large wind turbine main shaft transfer device. Background Technology

[0002] Large-scale wind power equipment refers to equipment that uses wind energy to generate electricity or wind power. The main shaft used in such equipment is a component used to transmit torque.

[0003] In existing technologies, large wind turbine main shafts are often transported using brackets. The brackets support the large wind turbine main shafts, facilitating their movement during transport.

[0004] However, the traditional brackets used for transporting large wind turbine main shafts have a relatively limited function. The brackets can only support the large wind turbine main shaft but cannot position it, which affects the stability of the large wind turbine main shaft during transport. This can lead to the large wind turbine main shaft slipping on the bracket during transport, and there is a risk that it will fall off the bracket.

[0005] Therefore, we need a positioning bracket and a large wind turbine main shaft transfer device to solve the problem that existing brackets cannot stably transfer large wind turbine main shafts, and to enable stable transfer of large wind turbine main shafts. Summary of the Invention

[0012] Preferably, the positioning posts are provided in two sets, and the two sets of positioning posts are symmetrically fixed on both sides of the inner end surface of the bracket.

Multiple annular grooves are provided, and the multiple annular grooves are evenly distributed, and the annular grooves and sliding grooves are connected, and the widths of the annular grooves and sliding grooves are equal. The positioning grooves are provided in two sets, and the two sets of positioning grooves are symmetrically distributed on both sides of the left and right surfaces of the outer wall of the annular grooves, and the widths of the positioning grooves and sliding grooves are equal.

[0013] Preferably, the positioning blocks are provided in two sets, and the two sets of positioning blocks are symmetrically fixed on both sides of the inner end surface of the extension rod.

[0015] Preferably, there are multiple limiting cylinders, which are uniformly fixed on the surface of the connecting plate. The outer surface of the limiting cylinder is cut into a plane, and the adjusting groove is opened on the top surface of the limiting cylinder.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention proposes a positioning bracket: The distance between connecting plates is increased by pulling an extension rod outward. When the extension rod is pulled, a positioning block moves in a groove. After the extension rod is pulled to a suitable length, it is rotated to change the orientation of the positioning block. When the positioning block rotates to the positioning groove in the annular groove, the extension rod is pulled outward, causing the positioning block to engage in the positioning groove and position the extension rod. A large wind turbine main shaft is placed on the bracket and initially limited by a limiting groove to prevent it from rolling left and right. Then, a turntable rotates a threaded rod, driving the connecting plate inward until a limiting cylinder abuts against the end of the large wind turbine main shaft, positioning it and achieving stability on the bracket. This prevents the large wind turbine main shaft from slipping during transport and relocation. By significantly adjusting the spacing between the connecting plates by pulling the extension rod, and then finely adjusting the position of the connecting plates by rotating the threaded rod, the positioning cylinder facilitates the positioning of large wind turbine main shafts. The adjustable extension rod allows the positioning cylinder to clamp and position large wind turbine main shafts of different lengths, ensuring stability during transport and movement on the bracket. By pulling the lifting block upwards to pull the pressure plate, and rotating the pressure plate to adjust its position above the large wind turbine main shaft, and then loosening the lifting block, the pressure plate, driven by the spring's elasticity, moves downwards to press against the end of the large wind turbine main shaft, further reinforcing it and improving its stability when placed on the bracket. This solves the problem of existing brackets being unable to stably transport large wind turbine main shafts, enabling stable transport of large wind turbine main shafts. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 The present invention provides a technical solution: a positioning bracket;

[0033] Example 1:

[0034] To improve the performance of the bracket 1, a limiting groove 11 is formed on the surface of the bracket 1, and a positioning post 10 is provided on the surface of the bracket 1. A storage groove 20 is formed on the surface of the positioning post 10, and a sliding groove 21 and an annular groove 22 are formed on the surface of the storage groove 20. A positioning groove 23 is formed on the surface of the annular groove 22. A positioning block 12 is provided on the surface of the extension rod 2, and a threaded groove 19 is formed on the surface of the extension rod 2. A threaded rod 3 is provided in the threaded groove 19. A turntable 13 and a connecting block 14 are provided on the surface of the threaded rod 3. A limiting cylinder 4 and a housing 18 are provided on the surface of the connecting plate 5. The inner end of the extension rod 2 is located in the storage groove 20. By pulling the extension rod 2 outward, the distance between the connecting plates 5 is increased. When the extension rod 2 is pulled out, the positioning block 12 moves in the sliding groove 21. After the extension rod 2 is pulled out to a suitable length, it is rotated to change the orientation of the positioning block 12. When the positioning block 12 rotates from the annular groove 22 to the positioning groove 23, the extension rod 2 is pulled outward, causing the positioning block 12 to lock. The extension rod 2 is positioned in the positioning groove 23. The large wind turbine main shaft 8 is placed on the bracket 1 and initially limited by the limiting groove 11 to prevent it from rolling left and right. Then, the threaded rod 3 is rotated by the turntable 13 to drive the connecting plate 5 to move inward until the limiting cylinder 4 abuts against the end of the large wind turbine main shaft 8 to position it, thus achieving its stability on the bracket 1 and preventing the large wind turbine main shaft 8 from slipping when the bracket 1 is moved. The distance between the connecting plates 5 is first adjusted by pulling the extension rod 2, and then the position of the connecting plate 5 is finely adjusted by rotating the threaded rod 3. This makes it convenient for the limiting cylinder 4 to position the large wind turbine main shaft 8. The adjustability of the extension rod 2 allows the limiting cylinder 4 to clamp and position large wind turbine main shafts 8 of different lengths, ensuring its stability when moved on the bracket 1. This solves the problem that existing brackets cannot stably transport large wind turbine main shafts, and can stably transport large wind turbine main shafts.

[0035] Example 2:

[0036] To further improve the stability of the large wind turbine main shaft 8 placed on the bracket 1, based on Embodiment 1, an adjustment groove 17 is provided on the surface of the limiting cylinder 4. The adjustment groove 17 is located on the top surface of the limiting cylinder 4, and a guide rod 6 is provided in the adjustment groove 17. The surface of the guide rod 6 is provided with a pressure plate 9 and a partition plate 16, and a spring 15 is sleeved on the guide rod 6. The top end of the guide rod 6 extends through the top of the adjustment groove 17. The pressure plate 9 is V-shaped and fixed to the top surface of the guide rod 6. The lifting block 7 is fixed to the outside of the top surface of the pressure plate 9, and the bottom end of the pressure plate 9 presses against the outer end surface of the large wind turbine main shaft 8. The partition plate 16 is fixed to the bottom end surface of the guide rod 6, and the spring... The bottom end of spring 15 rests against the surface of partition 16, and spring 15 is located in adjustment groove 17. The top end of spring 15 rests against the inner top surface of adjustment groove 17. By pulling the pressure plate 9 upward with lifting block 7 and rotating the pressure plate 9 to adjust its position so that it is above the large wind turbine main shaft 8, the lifting block 7 is loosened, and the pressure plate 9 moves downward by the elasticity of spring 15 to press against the end of the large wind turbine main shaft 8 to reinforce it. This further improves its stability when placed on bracket 1, thereby making it more convenient to transport and move. This further solves the problem that existing brackets cannot stably transport large wind turbine main shafts, and can stably transport large wind turbine main shafts.

[0037] Example 3:

[0038] Based on Example 2, a method for using a positioning bracket and a large wind turbine main shaft transfer device is proposed:

[0039] Step 1: Stabilize the connection. Increase the distance between the connecting plates 5 by pulling the extension rod 2 outward. When the extension rod 2 is pulled out, the positioning block 12 moves in the slide groove 21. After the extension rod 2 is pulled to a suitable length, rotate it to change the orientation of the positioning block 12. When the positioning block 12 rotates from the annular groove 22 to the positioning groove 23, pull the extension rod 2 outward so that the positioning block 12 is locked into the positioning groove 23 to position the extension rod 2. Place the large wind turbine main shaft 8 on the bracket 1 and initially limit it through the limiting groove 11 to prevent it from rolling left and right. Then, rotate the threaded rod 3 through the turntable 13 to drive it. The connecting plate 5 moves inward until the limiting cylinder 4 abuts against the end of the large wind turbine main shaft 8 to position it, thereby achieving its stability on the bracket 1 and preventing the large wind turbine main shaft 8 from slipping during the transfer and relocation of the bracket 1. First, the distance between the connecting plates 5 is adjusted significantly by pulling the extension rod 2, and then the position of the connecting plate 5 is finely adjusted by rotating the threaded rod 3. This makes it convenient for the limiting cylinder 4 to position the large wind turbine main shaft 8. The adjustability of the extension rod 2 enables the limiting cylinder 4 to clamp and position large wind turbine main shafts 8 of different lengths, ensuring their stability during the transfer and relocation of the bracket 1.

[0040] Step 2: Stabilization 2. Pull the pressure plate 9 upward by lifting block 7, rotate the pressure plate 9 to adjust its position so that it is above the large wind turbine main shaft 8, loosen the lifting block 7, and the pressure plate 9 is driven downward by the elasticity of the spring 15 to press and hold the end of the large wind turbine main shaft 8 to reinforce it, further improving its stability when placed on the bracket 1, and thus realizing the convenience of its transfer and relocation.

[0041] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
