Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance of wind power generation equipment, and particularly relates to a maintenance platform for large-scale wind power generation equipment. Background Art

[0002] Large-scale wind power generation equipment usually refers to large-scale wind turbines, also known as wind generators. These devices convert wind energy into mechanical energy and finally into electrical energy. Large-scale wind power generation equipment is usually installed in areas with rich wind energy resources, such as coastlines, highlands or open plains. They can operate independently or form a wind farm to generate electrical energy more efficiently. During the maintenance process of wind power generation equipment, a lifting platform is usually used to lift workers to the top of the power generation equipment.

[0003] In the prior art, a Chinese patent with the publication number "CN218290048U" discloses a manned platform inside a tower barrel for preventing shaking during maintenance of wind power generation equipment. By setting an electric winch and a steel wire rope connected to the manned platform, the manned platform can be driven to lift and lower; two side slide rails are set to be slidably connected to the manned platform, and the electric winch is used to drive the manned platform to lift and lower stably and evenly, so as to prevent shaking during maintenance. This solves the problems that the existing workrooms at the top of the tower barrel all rely on vertical steel frame ladders, and it is a very laborious and time-consuming physical task to climb to the tower top workroom of the tower barrel through the steel frame ladders, with a large work intensity, low work efficiency, and at the same time there are safety hazards, it is inconvenient to use and not convenient to provide safer personal protection for maintenance personnel.

[0004] However, there are still great deficiencies in the prior art, such as:

[0005] During the process of driving the manned platform to lift and lower, due to the high design height of the tower barrel of the wind power generation equipment, the lifting height required is also very high, and strict requirements are imposed on the motor and the steel cable. There is a lack of anti-falling function during the lifting process, and only the steel wire rope is relied on to bear the weight of the entire equipment, so the stability cannot be guaranteed. When the steel wire rope lacks maintenance, it is easy to break, which has an impact on the personal safety of the staff.

[0006] Therefore, we provide a maintenance platform for large-scale wind power generation equipment to solve the above problems. Content of the Utility Model

The electric push rod 11 can drive the limiting box 8 and the limiting block 9 to move. When it is necessary to move the hanging box 3 downward, the limiting block 9 can be disengaged from the limiting groove 7. Specific Embodiment 2

[0037] Please refer to Figures 1-6, on the basis of the first specific embodiment, a through opening 12 is provided inside the support frame 4. One side of the support sleeve 6 is fixedly connected to the hanging box 3. The driving assembly includes a partition plate 13, which is fixedly connected inside the cylinder body 1. A driving motor 14 is fixedly connected to the top of the partition plate 13. The output end of the driving motor 14 is fixedly connected to a winding roller 15. A steel cable 16 is fixedly connected to the surface of the winding roller 15. A hanging ring 17 is fixedly connected to the top of the hanging box 3. The bottom of the steel cable 16 passes through the partition plate 13 and is fixedly connected to the hanging ring 17. The reset assembly further includes a spring 18, which is fixedly connected inside the limit box 8. The output end of the electric push rod 11 passes through the driving box 10 and is fixedly connected to a support block 19. The other side of the support block 19 is fixedly connected to the limit box 8. The other end of the spring 18 is fixedly connected to the inner wall of the limit box 8. The other side of the limit block 9 penetrates into the support sleeve 6. Box doors 20 are movably connected to both sides of the hanging box 3. A handle is fixedly connected to one side of the box door 20. A protective frame 21 is fixedly connected to one side of the ladder 2. The other side of the protective frame 21 is fixedly connected to the support frame 4. A buffer damper 22 is installed inside the cylinder body 1. The top of the buffer damper 22 is fixedly connected to a buffer plate 23.

[0038] Specifically: The number of through openings 12 inside the support frame 4 is the same as that of the protective frame 21. The size of the through opening 12 is eighty centimeters by eighty centimeters. When the driving device fails and the steel cable 16 loses its supporting force, causing the hanging box 3 to be stuck on the guide rail plate 5 by the limit block 9, the staff inside the hanging box 3 can manually open the cabinet door on the right side of the hanging box 3, climb out of the hanging box 3 through the through opening 12, and enter the protective frame 21, and climb up or down through the ladder 2 to get out of danger. The driving motor 14 is a self-locking motor in the prior art and has its own function to prevent the steel cable 16 from slipping abnormally. The steel cable 16 is connected between the winding roller 15 and the hanging box 3 and can pull the hanging box 3 when the winding roller 15 rotates. The spring 18 has the function of compressing and storing energy and can elastically reset the support block 19. The box doors 20 installed on both sides of the hanging box 3 can be used for the staff to enter and exit. The protective frame 21 is designed in an arc shape and is fixed on the surface of the climbing frame, which can play a protective role for the staff. Through the buffer damper 22 and the buffer plate 23, the falling of the hanging box 3 can be buffered, further improving the buffering effect.

[0039] The working principle of the present utility model is as follows: After the staff sits in the hanging box 3, the driving motor 14 is started through an external controller. The driving motor 14 cooperates with the winding roller 15 to wind up the steel cable 16. The steel cable 16 cooperates with the pull ring to pull the hanging box 3 upward. While the hanging box 3 is being pulled upward, it drives the support sleeve 6 to slide on the surface of the guide rail plate 5, so that the hanging box 3 can move vertically up and down.

[0040] When the hanging box 3 moves upward, it will drive the limit box 8 to move. The limit box 8 drives the limit block 9 to move upward. When the limit block 9 moves upward, it will be squeezed by the inner wall of the limit groove 7. After being pushed, the limit block 9 will squeeze the spring 18. When the steel cable 16 breaks and the hanging box 3 loses the pulling force, the hanging box 3 moves downward. At this time, the spring 18 will reset the limit block 9, so that the limit block 9 is inserted into the limit groove 7 again, and the hanging box 3 is supported by the limit block 9 to play a role in preventing falling.
