This platform is connected to the concrete tower wall via brackets, thus requiring a large load-bearing capacity and a 20-year service life. However, vibrations generated during wind turbine operation can cause the steel strands to swing and rub against the brackets, leading to strand breakage. Furthermore, the existing permanent platform brackets on the concrete tower cannot be adjusted in angle, and manufacturing and installation errors can cause misalignment of the mounting holes with the platform beams during construction, making installation impossible.

One side of the bracket body is fixed to the inner wall of the tower, and the other side is provided with two arc-shaped mounting holes for connecting the platform beams of the tower. The two arc-shaped mounting holes are arranged in a mirror symmetrical manner. The bracket body can be adjusted along the circumferential direction through the two arc-shaped mounting holes, thereby connecting the platform beams in different directions. There are two anti-friction plates, symmetrically arranged at the other two ends of the bracket body, to prevent cutting the steel strands of the wind turbine tower.

[0006] Furthermore, the corbel body includes a back plate, a front plate, and side plates. One side of the front plate is perpendicularly connected to the back plate. The back plate is provided with two waist-shaped holes for connecting to the inner wall of the mixing tower. The other side of the front plate is provided with two arc-shaped mounting holes for connecting the platform beam. The two arc-shaped mounting holes are arranged in a mirror symmetrical manner. There are two side plates, symmetrically arranged at the other two ends of the front plate. Two anti-friction plates are respectively provided on the outer side of the two side plates. Each side plate is provided with multiple connection holes for connecting the anti-friction plates.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] like Figure 1As shown, this embodiment provides a wind power hybrid tower bracket with multi-angle adjustment and wear-resistant steel strands, including a bracket body 1 and an anti-friction plate 2. One side of the bracket body 1 is fixed to the inner wall of the hybrid tower, and the other side is provided with two arc-shaped mounting holes 1021 for connecting platform beams. The two arc-shaped mounting holes 1021 are arranged in a mirror symmetrical manner. The bracket body 1 can be adjusted along the circumferential direction through the two arc-shaped mounting holes 1021, thereby connecting platform beams 3 in different directions. There are two anti-friction plates 2, which are symmetrically arranged at the other two ends of the bracket body 1 to prevent the steel strands of the wind power hybrid tower from being cut.

[0023] like Figures 2 to 4 As shown, the bracket body 1 includes a back plate 101, a front plate 102, and side plates 103. One side of the front plate 102 is perpendicularly connected to the back plate 101. The back plate 101 is provided with two waist-shaped holes 1011 for connecting to the inner wall of the mixing tower. During installation, the left and right positions of the bracket can be adjusted through the waist-shaped holes 1011 for easy installation. The other side of the front plate 102 is provided with two arc-shaped mounting holes 1021 for connecting the platform beam. The two arc-shaped mounting holes 1021 are arranged in a mirror symmetrical manner and their centers coincide. There are two side plates 103, which are symmetrically arranged at the other two ends of the front plate 102. Two anti-friction plates 2 are respectively provided on the outer surface of the two side plates 103, and the shape and size of the side plates 103 are the same as the shape and size of the anti-friction plates 2. Each side plate 103 is provided with multiple connecting holes 1031 for connecting the anti-friction plates 2. In this embodiment, three M8 threaded through holes are used as an example.

[0024] like Figure 5 As shown, the anti-friction plate 2 is provided with multiple countersunk holes 201 for connecting the bracket body 1. In this embodiment, three M8 countersunk holes are used as an example, which correspond one-to-one with the three M8 threaded through holes on the side plate 103. Finally, the anti-friction plate 2 is fixed to the side plate 103 with hexagon countersunk screws.

[0025] In this embodiment, the support bracket body is made of steel, which can be manufactured using Q355B steel. The anti-friction plate is made of TPU material, which has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance, low cost, and is wear-resistant and smooth, effectively preventing the support bracket from cutting the steel strands, significantly reducing the risk of steel strand breakage, and greatly improving the safety of the wind turbine operation.

[0026] This invention, through the design of the arc-shaped mounting hole, enables multi-angle adjustment. Experimental verification has shown that... Figure 6As shown, the adjustment range reaches 90°, meeting various installation requirements. After installation, the bracket has an overall width of 170mm, a length of 262mm, and a height of 300mm, with a total weight of only 13.4kg, making it easy to manufacture and install. Static stress analysis using ANSYS shows that under a load of 2 tons, the maximum deformation is only 0.55mm, and the maximum stress is only 276MPa, fully meeting the usage requirements.
