Description

Technical Field

[0001] This utility model relates to the field of maintenance platform technology, and in particular to an anti-slip maintenance platform for wind turbine generator nacelles. Background Technology

[0002] The anti-slip maintenance platform for wind turbine nacelles is a key facility to ensure the safety of maintenance personnel working inside the nacelle. Its anti-slip design prevents personnel from slipping due to oil stains, water accumulation, or equipment vibrations inside the nacelle. At the same time, it provides a stable working surface, making it convenient for personnel to place tools and carry out operations such as component inspection and maintenance, reducing safety risks during the maintenance process and ensuring that the maintenance of wind power equipment is carried out efficiently and safely.

[0003] In traditional engine room maintenance, toolboxes are often placed haphazardly in the corner of the platform, supported by simple fixed brackets, or carried by hand. The continuous vibration generated by engine room operation can easily cause unsecured toolboxes to slide or tip over, which may not only cause tools to be bumped and damaged, but also pose a safety hazard of tools falling from a height, threatening the equipment and personnel below the engine room. In response to this technical problem, this application proposes a wind turbine nacelle anti-slip maintenance platform. Utility Model Content

This platform features a movable rack that can hold and secure toolboxes in place, preventing them from sliding and falling to avoid safety risks. The rack position can also be adjusted as needed to reduce unnecessary movement of personnel to retrieve tools. This approach ensures operational safety, improves maintenance efficiency, and is suitable for the needs of dispersed work sites.

The outer wall of threaded rod 4 is rotatably connected to the inner wall of platform body 3. The outer wall of clamping plate 5 is slidably connected to the inner wall of platform body 3 for clamping and fixing toolbox or adjusting the position of placement rack 6.

[0019] For details, please refer to Figure 2 The ladder 1 is fixed to the bottom of the wind turbine generator set. The platform body 3 is moved from bottom to top by the lifting mechanism 2. The lifting mechanism 2 is a motor with two winding rollers fixed to the motor drive end. A guide roller rotates at the top of the ladder 1. A steel cable is fixed to the outer wall of the winding roller. The steel cable passes through the guide roller and is connected to the top of the platform body 3. When the platform body 3 needs to be raised or lowered, the motor is started to drive the steel cable to wind up and raise or lower the platform body 3. At the same time, a controller is set inside the platform body 3. The controller is electrically connected to the motor. An anti-slip groove is opened on the lower side inside the platform body 3. The toolbox is clamped and fixed by the left and right movable placement rack 6 to prevent the toolbox from sliding and falling to avoid safety risks. The position of the placement rack 6 can also be adjusted as needed to reduce the ineffective movement of personnel to retrieve tools. This not only ensures the safety of operation but also improves the maintenance efficiency and adapts to the needs of dispersed work points.

[0020] Reference Figure 1 , Figure 6 and Figure 7As shown, a rotating rod 24 is rotatably connected to the inner wall of the platform body 3. The outer wall of the railing 23 is slidably connected to the inner wall of the rotating rod 24. The outer wall of the platform body 3 is slidably connected to the inner wall of the ladder 1. A threaded rod 20 is rotatably connected to the inner wall of the rotating rod 24. A slider 21 is threadedly connected to the outer wall of the threaded rod 20. A transmission rod 22 is rotatably connected to the inner wall of the slider 21. The other end of the transmission rod 22 is rotatably connected to the inner wall of the railing 23. The outer wall of the slider 21 is slidably connected to the inner wall of the rotating rod 24. The inner wall of the rotating rod 24 rotates... A crank 18 is connected to the rotating rod 24. A gear set 19 is fixedly connected to the right end of the crank 18. The other end of the gear set 19 is fixedly connected to the left end of the threaded rod 20. A groove 17 is provided on the inner wall of the rotating rod 24. A locking rod 15 is provided on the inner wall of the groove 17. A spring 16 is fixedly connected to the top of the locking rod 15. The other end of the spring 16 is fixedly connected to the inner wall of the platform body 3. The outer wall of the locking rod 15 is slidably connected to the inner wall of the platform body 3. The shape of the locking rod 15 matches the groove 17 to adjust the height of the fence 23.

[0021] Specifically, the gear set 19 consists of bevel gears meshing on both sides. By adjusting the height of the fence 23, it can adapt to different maintenance scenarios in the engine room, enhance protection, avoid the risk of falling, and save space when personnel pass through or equipment is moved. It balances operational safety and ease of operation, and solves the limitations of the fixed-height fence 23.

[0022] Working principle: First, when using the platform body 3, pull the lever 15 upwards to remove it from the groove 17. Then, rotate the rotating rod 24 and the fence 23 outwards, allowing the maintenance worker to enter the platform body 3. Close it in the same way, and use the spring 16 to insert the lever 15 into the groove 17 to limit the rotation rod 24. At the same time, manually turn the crank handle 18. The crank handle 18 drives the gear set 19 to rotate, which in turn drives the threaded rod 20 to rotate, thereby causing the slider 21 on the outer wall to slide. This, in turn, drives the transmission rod 22 to rotate, pushing the fence 23 upwards to adjust its height. Place the toolbox in the rack 6 and turn the knob 9. The knob 9 drives the gear 10 to rotate, which in turn drives the toothed plates 11 on both sides and the limiting blocks 12 to move inwards. By sliding the limit block 12 out of the limit groove 13, the clamping plate 8 can be pushed backward to contact and clamp the toolbox. After clamping, the knob 9 is released, and the torsion spring 14 drives the knob 9 to rotate in the opposite direction, inserting the limit blocks 12 on both sides into the limit groove 13 to complete the clamping of the toolbox. At the same time, the threaded rod 4 can be rotated to drive the clamping plate 5 to slide upward and remove the clamping plate 5 from the slot 7, so that the placement frame 6 can be moved. The position of the placement frame 6 can be adjusted left and right. After adjustment, the threaded rod 4 is rotated in the opposite direction to insert the clamping plate 5 into the slot 7 to fix the placement frame 6. The lifting mechanism 2 can be started through the controller inside the platform body 3 to pull the platform body 3 upward for lifting and maintenance of different positions of the unit.
