[0012] Beneficial effects
[0013] The wind power electric lifting device has the following beneficial effects: in terms of portability, the traditional wind power auxiliary lifting equipment is very inconvenient to transport and move in narrow wind power equipment space due to its large size and heavy weight. The device is designed to be light and small, can easily adapt to various wind power operation scenes, realize rapid transfer and deployment, not only reduces the cost of manual carrying, but also greatly reduces the time consumption, and significantly improves the mobility and flexibility of on-site operation.

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0022] Example
[0023] like Figures 1-3 As shown, the support base plate 2 is installed on the inner side of the horn-shaped limiting bracket 1, the lifting support structure is installed on the support base plate 2, and the lifting platform 3 is installed on the lifting support structure. The lifting support structure includes: two pairs of lifting support blocks 4, two pairs of adsorption electromagnets 5, a lifting limiting box 6, a lifting limiting loop block 7, a pair of lifting threaded rods 8, a pair of lifting threaded pipes 9, a lifting gear set 10, a lifting drive motor 11, a lifting loop support block 12, a lifting inner loop block 13, a lifting rack 14, a lifting auxiliary drive motor 15, a lifting auxiliary gear 16, a lifting slide rail set 17, a lifting slider set 18, and a lifting inner support block 19.
[0024] Specifically, two pairs of lifting support blocks 4 are installed on the horn-shaped limiting bracket 1, two pairs of adsorption electromagnets 5 are respectively installed on the two pairs of lifting support blocks 4, the lifting limiting box 6 is installed on the supporting base plate 2, the lifting loop support block 12 is installed on the inner side of the lifting limiting box 6, a pair of lifting threaded rods 8 are respectively inserted into the lifting limiting loop block 7 and the lifting limiting box 6 through bearings, a pair of lifting threaded tubes 9 are inserted into the lifting loop support block 12, and the pair of lifting threaded tubes 9 are respectively movably fitted onto the pair of lifting threaded rods 8, the lifting gear set 10 is fitted onto the pair of lifting threaded rods 8, the driving end of the lifting drive motor 11 is connected to the lifting threaded rods 8, and the lifting inner... A loop block 13 is installed on the lifting loop support block 12. The lifting inner support block 19 is movably inserted into the inner side of the lifting inner loop block 13. The lifting slide rail assembly 17 is installed on the inner side of the lifting inner loop block 13. The lifting slider assembly 18 is installed on the outer side of the lifting inner loop block 13, and the lifting slider assembly 18 is movably inserted into the inner side of the lifting slide rail assembly 17. A drive groove is provided on the telescopic lifting inner loop block 13. The lifting rack 14 is installed on the lifting inner support block 19. The lifting auxiliary drive motor 15 is installed on the lifting inner loop block 13. The lifting auxiliary gear 16 is installed on the drive end of the lifting auxiliary drive motor 15, and the lifting auxiliary gear 16 meshes with the lifting rack 14.
[0025] It should be noted that, in the above, for the wind power yaw brake in the replacement or tooling installation process in the face of positioning and height control problems, we designed a special lifting support structure. The structure can realize accurate control in the lifting process to ensure that the brake or tooling can be accurately installed to the predetermined position, thereby significantly improving the installation precision and work quality, and the electric lifting device is carefully carried to the specified position at the bottom of the equipment to be lifted. During the carrying process, the device needs to be kept horizontal and stable to avoid collision. Press the electromagnet switch. At this time, the electromagnet is quickly powered on to generate strong magnetic force and firmly adsorb on the metal surface of the work platform. Through the operation of the lifting drive machine 11, the lifting gear set 10 on the driving end of the lifting drive machine 11 is driven to rotate, and a pair of lifting threaded rods 8 on the lifting gear set 10 is rotated to drive the lifting threaded pipes 9 on the lifting threaded rods 8 to stably lift, thereby driving the lifting limit return blocks 7 on the lifting threaded pipes 9 to stably lift. Similarly, through the operation of the lifting auxiliary drive machine 15, the lifting auxiliary gear 16 on the driving end of the lifting auxiliary drive machine 15 is rotated to drive the lifting rack 14 on the lifting auxiliary gear 16 to stably lift. Through the cooperation of the gear and the rack and the cooperation of the threaded rod and the threaded pipe, stable and accurate lifting is realized. At the same time, through the lifting rack 14 on the lifting auxiliary drive machine 15, the lifting inner support block 19 is slowly pressed, and the lifting handle button is started. The electric adjustment lifting support structure lifting function is started.During the lifting process, the operator should pay attention to the lifting speed and position change of the lifting rod at all times, and realize accurate control through the fine adjustment of the handle, so that the lifting speed remains uniform and stable, avoiding rapid rise and fall, so that the lifting platform 3 driven by the lifting inner support block 19 can be lifted stably, and at the same time, the lifting limiting box 6 is limited by the horn-shaped limiting support 1, and the horn-shaped limiting support 1 is magnetically adsorbed and fixed by the two pairs of lifting support blocks 4 on the horn-shaped limiting support 1. The current variable fluid in the current variable fluid box is drained to the back-shaped expansion liquid bag through the liquid pump, the lifting back-shaped block and the lifting back-shaped support block 12 are expanded and extruded through the expansion of the back-shaped expansion liquid bag, and then the current variable fluid in the back-shaped expansion liquid bag is electrified to become hard through electrification, so as to achieve expansion and fixation. The portable and compact design of the device enables it to be easily transferred and deployed in various wind power operation scenes, reducing the cost and time consumption of manual handling and greatly improving the mobility of on-site operations. Through multi-stage lifting, the height of the entire device is reduced, thereby facilitating the handling of the entire device. Since the wind power yaw brake is heavy, ordinary tooling is difficult to stably carry and is prone to shaking and imbalance during lifting; the lifting tooling uses high-strength materials and optimized structural design to enhance the overall carrying capacity, and an electromagnet is installed at the bottom of the lifting tooling to firmly adsorb the yaw platform during lifting, ensuring safety and stability during lifting, and avoiding risks such as shaking and falling. At the same time, through the cooperation of the lifting slide group 17 and the lifting slide block group 18, as well as the lifting screw rod 8 and the lifting screw pipe 9, the effect of stable lifting is achieved. The traditional method is complex and labor-intensive. The lifting tooling introduces automatic control technology, such as electric lifting and remote control, so that the operator can conveniently control the lifting speed, height and direction, greatly simplifying the operation process, reducing labor input, improving work efficiency and reducing labor intensity. Different types and specifications of wind power yaw brakes and tooling have different requirements for lifting devices. The lifting tooling adopts a modular design concept, which can adjust the length of the lifting arm to complete installation or disassembly. After the operation, the operator holds the lifting support structure operating handle again, slowly presses the handle down button, and the lifting support structure descends stably, restores the lifting device to the initial position, turns off the electromagnet switch, removes the adsorption state, carefully removes the electric lifting device from the operation area, arranges and stores it in the designated place, and cleans and maintains the device for the next use.
