[0002] During the routine maintenance and repair of wind turbine equipment, workers often need to enter the confined space inside the wind turbine to perform their tasks. Existing wind turbine work platforms are either fixed in height, making it difficult to meet the needs of working at different heights and requiring frequent use of ladders and other auxiliary tools, which is not only inefficient but also poses significant safety hazards; or although they have lifting functions, they are inconvenient to move and cannot be flexibly adjusted at the wind turbine work site, making it impossible for workers to quickly reach the work point. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a liftable and mobile personnel platform for wind turbine operations, thereby solving the problems mentioned in the background section. This utility model features a novel structure, achieving vertical lifting through a lifting assembly and horizontal movement via a translation screw and slider groove structure. It eliminates the need for ladders or other auxiliary tools, allowing operators to quickly and accurately reach work points at different heights and locations within the wind turbine tower. The U-shaped lifting platform employs a U-shaped spatial architecture design, allowing its U-shaped notch to flexibly avoid pre-installed ladders, cable supports, and other fixed structures within the tower during lifting or translation, preventing collisions and interference between the platform and obstacles.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a liftable mobile work platform for wind turbine operation, comprising four vertical guide rails evenly distributed along the circumference of the inner wall of the wind turbine tower and a lifting screw penetrating the main body of the platform vertically. The four vertical guide rails are welded to the inclined support members through horizontal reinforcing rods to form a frame structure. A U-shaped lifting platform is arranged inside the four vertical guide rails. A lifting assembly is arranged between the U-shaped lifting platform and the lifting screw. A translation plate is arranged between the inner walls of the two sides of the U-shaped lifting platform. Two fixing plates that cooperate with the vertical guide rails are fixedly connected to both outer sides of the U-shaped lifting platform.

[0005] Furthermore, the vertical guide rails are located between the two fixed plates and slide in cooperation with them, and guide grooves are provided on the inner sides of the four vertical guide rails.

[0006] Furthermore, the U-shaped lifting platform has grooves on both sides of its outer surface that are located between two fixed plates. A rotating shaft is rotatably fitted between the inner walls of the two sides of the groove, and a guide wheel that cooperates with the guide groove is fixedly connected to the middle of the rotating shaft.

[0007] Furthermore, the lifting assembly includes a first servo motor fixedly installed on the U-shaped lifting platform. A through groove is provided through the upper side of the U-shaped lifting platform, and a threaded cylinder that is threadedly engaged with the lifting screw is rotatably fitted on the inner wall of the through groove.

[0008] Furthermore, the inner wall of the through groove is provided with an annular limiting groove, and the outer wall of the threaded cylinder is fixedly connected with an annular block that rotatably fits in the annular limiting groove.

[0009] Furthermore, the output shaft of the first servo motor is fixedly connected to a worm gear, and the outer wall of the threaded cylinder is fixedly connected to a worm wheel that meshes with the worm gear.

[0010] Furthermore, an installation groove is provided on the inner wall between the two sides of the U-shaped lifting platform. A second servo motor is fixedly installed on the inner wall of the installation groove, and the output shaft of the second servo motor is fixedly connected to a translation screw.

[0011] Furthermore, a threaded hole is provided on one side of the translation plate to engage with the threaded screw, and sliding grooves are provided on the inner walls of both sides of the U-shaped lifting platform. Slider blocks that slide in cooperation with the sliding grooves are fixedly connected to both sides of the translation plate. A guardrail is fixedly connected to the upper side of the translation plate, and a controller is fixedly installed on the upper side of the guardrail. The controller is electrically connected to the first servo motor and the second servo motor.

[0012] The beneficial effects of this utility model are: 1. This wind turbine operation mobile lifting platform achieves vertical lifting through lifting components and horizontal movement through translation screws and slider groove structures. It does not require ladders or other auxiliary tools, allowing operators to quickly and accurately reach work points at different heights and positions inside the wind turbine tower. The U-shaped lifting platform adopts a U-shaped spatial structure design.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 6 This utility model provides a technical solution: a mobile lifting platform for wind turbine operation, comprising four vertical guide rails 1 evenly distributed along the circumference of the inner wall of the wind turbine tower and a lifting screw 2 vertically penetrating the main body of the platform. The four vertical guide rails 1 are welded to the inclined support members through horizontal reinforcing rods to form a frame structure. A U-shaped lifting platform 3 is provided inside the four vertical guide rails 1. A lifting assembly 4 is provided between the U-shaped lifting platform 3 and the lifting screw 2. A translation plate 5 is provided between the inner walls of the two sides of the U-shaped lifting platform 3. Two fixing plates 6 that cooperate with the vertical guide rails 1 are fixedly connected to both sides of the outer sides of the U-shaped lifting platform 3.

[0018] In this embodiment, the vertical guide rail 1 is located between two fixed plates 6 and is slidably engaged with them. The inner sides of the four vertical guide rails 1 are provided with guide grooves 8. The two outer sides of the U-shaped lifting platform 3 are provided with grooves 9 located between the two fixed plates 6. The inner walls of the two sides of the grooves 9 are rotatably engaged with a rotating shaft 10. The middle of the rotating shaft 10 is fixedly connected with a guide wheel 11 that engages with the guide groove 8.

[0019] like Figure 6As shown, the lifting assembly 4 includes a first servo motor 401 fixedly installed on a U-shaped lifting platform 3. A through groove 402 is provided through the upper side of the U-shaped lifting platform 3. A threaded cylinder 403 that is threadedly engaged with the lifting screw 2 is rotatably fitted on the inner wall of the through groove 402. An annular limiting groove 404 is provided on the inner wall of the through groove 402. An annular block 405 that is rotatably fitted in the annular limiting groove 404 is fixedly connected to the outer wall of the threaded cylinder 403. A worm gear 406 is fixedly connected to the output shaft of the first servo motor 401. A worm wheel 407 that meshes with the worm gear 406 is fixedly connected to the outer wall of the threaded cylinder 403.

[0020] Specifically, when the platform height needs to be adjusted, the controller 19 sends a start command to the first servo motor 401. The first servo motor 401 drives the worm gear 406 to rotate. Through the meshing transmission between the worm gear 406 and the worm wheel 407, the threaded cylinder 403 is driven to rotate. Since the threaded cylinder 403 is threadedly engaged with the lifting screw 2, and the annular block 405 rotates within the annular limiting groove 404, the axial movement of the threaded cylinder 403 is restricted. Therefore, the rotation of the threaded cylinder 403 is converted into the vertical lifting motion of the U-shaped lifting platform 3 along the lifting screw 2. At the same time, the fixed plates 6 on both sides of the U-shaped lifting platform 3 slide on the vertical guide rail 1, and the guide wheel 11 rolls within the guide groove 8, ensuring the stability and precise guidance of the platform lifting process.

[0021] In this embodiment, the inner wall between the two sides of the U-shaped lifting platform 3 is provided with an inwardly opening mounting groove 12. A second servo motor 13 is fixedly installed on the inner wall of the mounting groove 12. The output shaft of the second servo motor 13 is fixedly connected to a translation screw 14. A threaded hole 15 is provided on one side of the translation plate 5, which is threadedly engaged with the translation screw 14. Sliding grooves 16 are provided on the inner walls of both sides of the U-shaped lifting platform 3. Sliding blocks 17 that slide in cooperation with the sliding grooves 16 are fixedly connected to both sides of the translation plate 5. A guardrail 18 is fixedly connected to the upper side of the translation plate 5. A controller 19 is fixedly installed on the upper side of the guardrail 18. The controller 19 is electrically connected to the first servo motor 401 and the second servo motor 13.

[0022] Specifically, to adjust the position of the translation plate 5, the controller 19 controls the second servo motor 13 to start, and the second servo motor 13 drives the translation screw 14 to rotate. The translation plate 5, which is threadedly engaged with the translation screw 14, moves horizontally along the inner wall of the U-shaped lifting platform 3 under the guidance of the slider 17 and the slide groove 16, thereby meeting the needs of operators to work in different lateral positions.

[0023] When operators need to adjust the platform position, they first issue an operation command through the controller 19 on the guardrail 18. If the platform height needs to be adjusted, the controller 19 sends a start signal to the first servo motor 401. The first servo motor 401 then drives the worm gear 406 to rotate. The worm gear 406 meshes with the worm wheel 407, thereby driving the threaded cylinder 403 to rotate. Since the threaded cylinder 403 is threadedly engaged with the lifting screw 2, and the annular block 405 rotates within the annular limiting groove 404, restricting the axial movement of the threaded cylinder 403, the rotation of the threaded cylinder 403 is transformed into a U-shaped lifting platform. 3. The platform is vertically raised and lowered along the lifting screw 2. During this process, the fixed plates 6 on both sides of the U-shaped lifting platform 3 slide on the vertical guide rail 1, and the guide wheel 11 rolls in the guide groove 8 to ensure that the platform is raised and lowered smoothly and the guidance is accurate. If it is necessary to adjust the horizontal position of the platform, the controller 19 controls the second servo motor 13 to start. The second servo motor 13 drives the translation screw 14 to rotate. The translation plate 5, which is threaded with the translation screw 14, moves horizontally along the inner wall of the U-shaped lifting platform 3 under the guidance of the slider 17 and the slide groove 16, thereby meeting the work needs of the operator in different horizontal positions.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
