Description
Technical Field
[0001] This utility model relates to the technical field of brake installation structure, and in particular to a yaw brake installation structure for a wind turbine generator. Background Technology
[0002] Against the backdrop of the global energy structure accelerating its transition to clean energy, wind power has become an important pillar of the energy sector due to its green and renewable characteristics. As a key component of the wind turbine control system, the yaw brake of a wind turbine is responsible for adjusting the direction of the turbine rotor to align with the wind direction, while also ensuring the safe braking of the turbine during extreme weather or equipment maintenance. As wind turbine units develop towards larger and higher power, the requirements for the installation structure of the yaw brake are becoming increasingly stringent. Traditional installation methods, due to unreasonable structural design and poor positioning accuracy, are prone to failures such as vibration and accelerated wear during brake operation, which restricts the efficient and stable operation of wind power equipment. Therefore, developing a wind turbine yaw brake installation structure that can ensure structural stability and precise installation is of great significance for improving the overall efficiency and safety of the wind power industry.
[0003] Existing wind turbine yaw brake installation methods mainly adopt simple direct fixing or shim adjustment structures. Some installation schemes directly fix the brake clamp body to the wind turbine nacelle base with bolts, and rely on manual measurement and experience to judge and adjust the position of the clamp body.
[0004] However, existing wind turbine yaw brake installation technology suffers from difficulties in ensuring the overall structural stability of the brake and the uniform distance between the upper and lower clamps and the brake disc. This leads to uneven force distribution and severe wear during brake operation. During the installation of offshore wind turbines, directly fixed brakes, lacking effective positioning and buffering structures, are prone to loosening of bolt connections under the severe vibrations of the wind turbine caused by strong winds. This results in structural displacement of the brake and inconsistent spacing between the upper and lower clamps and the brake disc. Consequently, the brake disc experiences excessive friction in certain areas, leading to abnormal wear. In severe cases, this can even cause the brake disc to deform and become unusable, affecting the normal operation and safety performance of the wind turbine. Therefore, a wind turbine yaw brake installation structure is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above deficiencies, this utility model provides a wind turbine yaw brake installation structure, which aims to improve the problem in the prior art that it is difficult to ensure the overall structural stability of the brake and that the distance between the upper and lower clamps and the brake disc is not uniform, resulting in inconsistent spacing between the upper and lower clamps and the brake disc.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A yaw brake mounting structure for a wind turbine includes an upper clamp body and a lower clamp body. A mounting pad is provided on the top of the upper clamp body, and a thin plate is provided on the top of the mounting pad. A brake disc is disposed between the upper and lower clamp bodies. Friction pads are fixedly connected inside both the upper and lower clamp bodies, and the friction pads contact the brake disc.

[0013] As a further description of the above technical solution:
[0014] A fixed column is fixedly connected inside the connecting frame, and a sliding column is slidably connected inside the fixed column.
[0015] As a further description of the above technical solution:
[0016] A locking block is fixedly connected to one end of the sliding column, and the locking block is in contact with the connecting block. A spring is sleeved on the outer wall of the sliding column, and the two ends of the spring are fixedly connected to the fixed column and the locking block, respectively.
[0017] As a further description of the above technical solution:
[0018] A connecting plate is fixedly connected to one side of the card block, and a slider is fixedly connected to one side of the connecting plate. The card block, the connecting plate, and the slider are all slidably connected inside the connecting frame.
[0019] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:
[0022] A limiting block is fixedly connected to one side of the slide bar, and the limiting block is in contact with the slide block.
[0023] This utility model has the following beneficial effects:
[0024] 1.

This achieves the effect of quick positioning and connection of the mounting pad. In actual operation, the staff can complete the positioning and connection of the mounting pad more quickly, saving a lot of time and labor costs, thereby improving the ease of installation of the yaw brake.

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.
[0035] Reference Figures 1-3 This utility model provides an embodiment of a wind turbine yaw brake installation structure, including an upper clamp body 3 and a lower clamp body 4, which are the main structures of the brake. Both are made of high-strength steel to ensure stability under the huge yaw torque and high load during the operation of the wind turbine. The upper clamp body 3 is provided with a mounting pad 2 on the top, which plays a role in stabilizing the structure and ensuring uniform force transmission. The mounting pad 2 is provided with a thin plate 1 on the top. A brake disc 5 is provided between the upper clamp body 3 and the lower clamp body 4. Friction pads 6 are fixedly connected inside the upper clamp body 3 and the lower clamp body 4. The friction pads 6 are in contact with the brake disc 5.

[0036] The fixing component includes mounting bolts 8, which pass through the upper clamp body 3 and the lower clamp body 4, and through the thin plate 1 and the mounting pad 2. The mounting bolts 8 pass through multiple holes in the upper clamp body 3, the lower clamp body 4, the thin plate 1 and the mounting pad 2, and are fixed between the thin plate 1 and the lower clamp body 4 by nuts 9 and nuts 10, respectively, to ensure the firmness and stability of the entire structure. The top end of the mounting bolt 8 is fixedly connected to the nut 9, which contacts the thin plate 1, and the bottom end of the mounting bolt 8 is threadedly connected to the nut 10, which contacts the lower clamp body 4.
[0037] Reference Figures 4-6The connecting assembly includes a connecting frame 11 and a connecting rod 12. One side of the connecting frame 11 is fixedly connected to one side of the thin plate 1, and one side of the connecting rod 12 is fixedly connected to one side of the mounting pad 2. The design of the connecting frame 11 allows the mounting pad 2 to be firmly connected to the thin plate 1 via the connecting rod 12. The connecting rod 12 is slidably connected inside the connecting frame 11, and a connecting block 13 is fixedly connected to the top of the connecting rod 12. The connecting block 13 is slidably connected inside the connecting frame 11. A fixing post 14 is fixedly connected inside the fixing post 14, and a sliding post 15 is slidably connected inside the fixing post 14. A locking block 16 is fixedly connected to one end of the sliding post 15. The locking block 16 contacts the connecting block 13.

The connecting block 13 will not slide or fall off during installation. A spring 17 is sleeved on the outer wall of the sliding column 15. The two ends of the spring 17 are fixedly connected to the inside of the fixed column 14 and the locking block 16, respectively.

A baffle 22 is fixedly connected to the outer wall of the sliding rod 20. A limit block 21 is fixedly connected to one side of the sliding rod 20. The limit block 21 is in contact with the slider 19. By pushing the sliding rod 20, the limit block 21 and the slider 19 can be moved together, so that the locking block 16 is separated from the connecting block 13, which facilitates quick disassembly and improves installation and maintenance efficiency.
[0038] Working principle: When installing the yaw brake of this wind turbine, firstly, the mounting pad 2 is attached to the bottom of the thin plate 1, and at the same time, the upper clamp body 3 and the lower clamp body 4 are attached to the bottom of the mounting pad 2. Then, the mounting bolt 8 passes through the thin plate 1, the mounting pad 2, the upper clamp body 3 and the lower clamp body 4 in sequence. The nut 9 is tightened on the top of the mounting bolt 8 and contacts the thin plate 1. The nut 10 is threaded to the lower clamp body 4 at the bottom and tightened. The upper clamp body 3, the lower clamp body 4, the mounting pad 2 and the thin plate 1 are firmly fixed together by bolt connection, ensuring the overall structure of the yaw brake is stable and the distance between the upper clamp body 3 and the lower clamp body 4 and the brake disc 5 is uniform vertically.
[0039] When installing the mounting pad 2, the thin plate 1 is connected to the connecting rod 12 of the mounting pad 2 through the connecting frame 11. The connecting block 13 on the connecting rod 12 can slide within the connecting frame 11. The locking block 16 on the sliding column 15 contacts the connecting block 13 under the action of the spring 17, restricting the movement of the connecting block 13. When it is necessary to remove the mounting pad 2, push the sliding rod 20. The sliding rod 20 drives the limiting block 21 to push the slider 19, the connecting plate 18 and the locking block 16 to overcome the elastic force of the spring 17, so that the connecting block 13 slides within the connecting frame 11, thereby achieving the effect of quick positioning and connection of the mounting pad 2.
