[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0017] In the existing technology, when replacing heavier components of wind turbines, there is a lack of dedicated lifting equipment, which cannot meet the requirements of efficient and safe operation, resulting in low efficiency and high safety risks in the maintenance of wind turbines.
[0018] In view of this, the present invention provides a lifting vehicle for wind turbine equipment maintenance. Through the cooperation of the vehicle frame, fixed frame, servo motor, reducer, worm gear screw jack, synchronous pulley, synchronous belt, threaded screw, lifting plate, control switch, battery, and protective sleeve, the maintenance components of the wind turbine are placed on top of the lifting plate. By controlling the servo motor, the threaded screw of the worm gear screw jack is driven to move up and down, achieving stable lifting and lowering of heavier maintenance components on top of the lifting plate. This improves the efficiency and safety of replacing and maintaining heavier components of the wind turbine, thereby increasing the work efficiency of wind turbine maintenance, shortening the installation and disassembly time of wind turbine components, and reducing the time cost of wind turbine downtime maintenance.
[0019] Depend on Figure 1-4It is known that a lifting vehicle for wind turbine equipment maintenance includes a frame 1. The frame 1 is made of high-strength steel as the main material, forming a sturdy and durable lifting vehicle body. A fixed frame 2 is fixedly connected to one side of the top of the frame 1. A servo motor 3 is installed above the fixed frame 2. A reducer 4 is installed at the output end of the servo motor 3. The reducer 4 is fixedly connected to the fixed frame 2. A worm gear screw jack 5 is fixedly connected to the top of the frame 1. Synchronous pulleys 6 are installed at the output end of the reducer 4 and the input end of the worm gear screw jack 5. A synchronous belt 7 is meshed with the outer wall of the synchronous pulley 6. A threaded screw 8 is installed inside the worm gear screw jack 5. A lifting plate 9 is fixedly connected to the top of the rod 8. The lifting plate 9 is fixed to the top of the threaded rod 8 and is used to support the components and tools used for the maintenance of the wind turbine equipment. A control switch 10 is fixedly connected to the top of the frame 1. The control switch 10 is electrically connected to the servo motor 3. A battery 11 is installed inside the frame 1. The battery 11 is electrically connected to the control switch 10. A protective sleeve 12 is fixedly connected to the outside of the threaded rod 8 inside the frame 1. The protective sleeve 12 protects the threaded rod 8 and prevents it from being impacted or worn during lifting and lowering, effectively extending the service life of the threaded rod 8 and ensuring the stability of the lifting plate 9.
[0020] In the specific implementation process, it is worth noting that the frame 1 uses high-strength steel as the main material to form a sturdy and durable lifting vehicle body. Through the cooperation of the frame 1, fixed frame 2, servo motor 3, reducer 4, worm gear screw jack 5, synchronous pulley 6, synchronous belt 7, and threaded screw 8, the servo motor 3 and worm gear screw jack 5 are both mounted on the top of the frame 1. By controlling the servo motor 3, the reducer 4 is driven to operate. The output end of the reducer 4 drives the input end of the worm gear screw jack 5 to rotate through the synchronous pulley 6 and synchronous belt 7, thereby driving the threaded screw 8 inside the worm gear screw jack 5 to perform stable lifting and lowering movements. Through the frame 1, fixed frame 2, servo motor 3, and worm gear screw jack 5... The reducer 4, worm gear screw jack 5, synchronous pulley 6, synchronous belt 7, threaded screw 8, and lifting plate 9 work together. The lifting plate 9 is fixed to the top of the threaded screw 8 and is used to support the components and tools used for wind turbine equipment maintenance. It can maintain stability under heavy load conditions. After the threaded screw 8 is raised to the top, the lifting height of the component is 1.8m. During the lifting process of the lifting plate 9, it can be manually held to prevent the lifting plate 9 from rotating during the lifting process. At the same time, during the workpiece installation process, the operator can rotate the lifting plate 9 to flexibly adjust the installation angle of the workpiece, improving the practicality and flexibility of the lifting vehicle. This is achieved through the frame 1, servo motor 3, control switch 10, and... The servo motor 3 is powered by the batteries 11, and can also be powered by an external power source, allowing the lifting vehicle to operate continuously even without an external power supply. The forward and reverse rotation of the servo motor 3 is controlled by the control switch 10, which in turn controls the lifting direction of the threaded screw 8, enabling height adjustment of the lifting plate 9 and maintenance components or tools. The protective sleeve 12 protects the threaded screw 8 from impact or wear during lifting, effectively extending its service life and ensuring the stability of the lifting plate 9. The system comprises a frame 1, a fixed frame 2, a servo motor 3, a reducer 4, a worm gear screw jack 5, and a synchronous pulley 6. The coordination between the synchronous belt 7, threaded screw 8, lifting plate 9, control switch 10, battery 11, and protective sleeve 12 allows the maintenance components of the wind turbine to be placed on top of the lifting plate 9. By controlling the servo motor 3, the threaded screw 8 of the worm gear screw jack 5 is driven to move up and down, achieving stable lifting and lowering of heavier maintenance components on top of the lifting plate 9. This improves the efficiency and safety of replacing and maintaining heavier components of the wind turbine, thereby increasing the work efficiency of wind turbine maintenance, shortening the installation and disassembly time of wind turbine components, and reducing the time cost of wind turbine downtime maintenance. The specific models of the servo motor 3, control switch 10, and battery 11 are not limited, as long as they meet the usage requirements.
[0021] Furthermore, the top two sides of the lifting plate 9 are provided with limiting edges 13, and the outer wall of the limiting edges 13 is provided with strap holes 14 at equal intervals. The bottom of the lifting plate 9 is fixedly connected with reinforcing ribs 15 at equal intervals.
[0022] In the specific implementation process, it is worth noting that, through the cooperation between the lifting plate 9, the limiting edge 13, the strap hole 14 and the reinforcing rib 15, the limiting edge 13 set on both sides of the top of the lifting plate 9 can limit the components of the wind turbine. At the same time, the strap hole 14 can be used to easily fix and tie the maintenance components to prevent the components from sliding or falling during the lifting process. Furthermore, the bottom of the lifting plate 9 is reinforced by the reinforcing rib 15, which enhances the load-bearing capacity and stability of the lifting plate 9, effectively reduces the risk of accidents caused by improper manual operation, and further improves the safety of maintenance operations.
[0023] Furthermore, a fixed box 16 is fixedly connected to the frame 1 below the servo motor 3. The battery 11 is located inside the fixed box 16. A limit door 17 is rotatably connected to one side of the outer wall of the fixed box 16. A fixed lock 18 is provided on one side of the limit door 17. The fixed lock 18 is connected to the fixed box 16.
[0024] In the specific implementation process, it is worth noting that through the cooperation between the frame 1, the battery 11, the fixed box 16, the limiting door 17 and the fixed lock 18, the battery 11 is placed inside the fixed box 16, and the limiting door 17 is fixed to the fixed box 16 by the fixed lock 18, thereby effectively protecting the battery 11 and preventing the battery 11 from being damaged or falling off during the movement or operation of the lifting vehicle, thus improving the safety of the battery 11.
[0025] Furthermore, a storage plate 19 is fixedly connected to the bottom of the frame 1, and limit plates 20 are provided at equal intervals on the top of the storage plate 19.
[0026] In the specific implementation process, it is worth noting that, through the cooperation between the frame 1, the storage plate 19 and the limiting plate 20, the storage plate 19 forms a storage space for storing tools and spare parts at the bottom of the frame 1, and the limiting plate 20 limits the tools and spare parts to prevent them from slipping during the movement or operation of the lifting vehicle. This can improve the efficiency of tool retrieval during maintenance operations and help improve the overall efficiency of maintenance operations.
[0027] Furthermore, movable wheels 21 are equidistantly rotatably connected to both sides of the bottom of the frame 1;
[0028] In the specific implementation process, it is worth noting that, through the cooperation between the frame 1 and the moving wheels 21, the bottom of the lifting vehicle is equipped with moving wheels 21 that can rotate and lock in 360 degrees. These wheels have good load-bearing capacity and mobility, enabling the lifting vehicle to carry heavy components and move them stably, making it convenient for maintenance personnel to move the components for maintenance quickly and stably.
