[0002] During the transportation of wind turbines, hoisting equipment is required for lifting and unloading. Current technology typically involves driving vehicles into the workshop and using overhead cranes for lifting. This method has certain limitations, thus necessitating the use of hoisting platforms. However, existing hoisting platforms lack a stable structure. During outdoor hoisting, the significant weight of the wind turbines makes the hoisting platform prone to swaying or even tipping over. Therefore, a structurally stable wind turbine hoisting platform is urgently needed. Utility Model Content

A second control component for controlling the rotation of the drive gear is installed within the platform body.
[0005] Preferably, the first control component includes a plurality of threaded cylinders located within the first receiving groove and rotatably connected to the inner wall of the first receiving groove. The threaded cylinders are arranged in a one-to-one correspondence with the limiting posts. The corresponding threaded cylinders are sleeved on the outside of the limiting posts. The outer wall of the limiting post located within the threaded sleeve has threads that mate with the threaded cylinders. A transmission gear is fixedly connected to the outer wall of the threaded cylinder. An intermediate gear meshes between two adjacent transmission gears. The intermediate gear is rotatably connected to the inner wall of the first receiving groove. A control motor is fixedly connected within the first receiving groove. The output shaft of the control motor is fixedly connected to any of the intermediate gears.
[0006] Preferably, the second control component includes a control column located within the second receiving groove and rotatably connected to the bottom wall of the second receiving groove. The control column passes through the drive gear and the mounting plate. The side wall of the control column has several vertical slots along its axial direction. The drive gear has several protrusions corresponding to the vertical slots. The protrusions are slidably located within the vertical slots. The control column is rotatably engaged with the mounting plate. A drive component for controlling the rotation of the several control columns is installed inside the platform body.
[0007] Preferably, the drive assembly includes a third receiving slot formed in the platform body, the top of the control column passing through the third receiving slot and located at the top of the platform body, a control gear rotatably connected to the control column in the third receiving slot, the control gears being arranged one-to-one with the control columns, the control column slidingly passing through the control gears, a slider adapted to the vertical groove being provided in the control gears, the slider slidingly located in the vertical groove; a rack slidably connected in the third receiving slot, a plurality of the control gears meshing with the rack, a telescopic electric cylinder fixedly connected in the third receiving slot, the output end of the telescopic electric cylinder being fixedly connected to the rack.
[0008] This utility model discloses the following technical effects: The first control component drives the limiting post to extend out of the platform body, inserting it into the ground to provide stability to the platform body.

[0014] 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.
[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Reference Figure 1-3 This utility model provides a wind turbine hoisting platform, including a platform body 1, on which a hoisting machine 2 is installed. A first receiving groove 3 is formed within the platform body 1, and several limiting posts 4 are arranged vertically within the first receiving groove 3. The limiting posts 4 penetrate the platform body 1 and slide along its axial direction with the platform body 1. A first control component is installed within the first receiving groove 3 to drive the limiting posts 4 out of the platform body 1. A second receiving groove 5 is formed within the limiting posts 4. A mounting plate 6 is fixedly connected inside the groove 5. Two horizontally arranged limiting strips 7 are slidably connected on the mounting plate 6. The two limiting strips 7 are symmetrically arranged about the axis of the limiting post 4. The limiting post 4 and the limiting strip 7 have openings corresponding to each other. A drive gear 8 is rotatably connected to the middle of the mounting plate 6. The limiting strip 7 has a toothed groove on the side close to the drive gear 8 that matches the drive gear 8. The drive gear 8 is located between the two limiting strips 7. A second control component for controlling the rotation of the drive gear 8 is installed inside the platform body 1.
[0017] In a further optimized scheme, the first control component includes a plurality of threaded cylinders 9 located within the first receiving groove 3 and rotatably connected to the inner wall of the first receiving groove 3. Each threaded cylinder 9 is correspondingly arranged with a limiting post 4. The corresponding threaded cylinder 9 is sleeved on the outside of the limiting post 4. The outer wall of the limiting post 4 located within the threaded sleeve has threads that mate with the threaded cylinder 9. A transmission gear 10 is fixedly connected to the outer wall of the threaded cylinder 9. An intermediate gear 11 meshes between two adjacent transmission gears 10. The intermediate gear 11 is rotatably connected to the inner wall of the first receiving groove 3. A control motor 12 is fixedly connected within the first receiving groove 3. The output shaft of the control motor 12 is fixedly connected to any one of the intermediate gears 11. By controlling the motor 12 to drive the intermediate gear 11 to rotate, the electric transmission gear 10 will rotate. Through the meshing of the transmission gear 10 and the intermediate gear 11, all the transmission gears 10 will rotate, which in turn will drive all the threaded cylinders 9 to rotate. Since the threaded cylinders 9 are threadedly engaged with the limiting post 4, and the limiting post 4 is slidably engaged with the platform body 1 along the axial direction, the limiting post 4 will be moved downward to extend out of the platform body 1 and move into the bottom surface.
[0018] In a further optimized design, the second control component includes a control column 13 located within the second receiving groove 5 and rotatably connected to the bottom wall of the second receiving groove 5. The control column 13 passes through the drive gear 8 and the mounting plate 6. The side wall of the control column 13 has several vertical slots 14 along its axial direction. The drive gear 8 has several protrusions corresponding to the vertical slots 14, which slide within the vertical slots 14. The control column 13 rotatably engages with the mounting plate 6. A drive assembly for controlling the rotation of the control columns 13 is installed within the platform body 1. The drive assembly drives the control columns 13 to rotate, which in turn electrically drives the gear 8 to rotate. During rotation, the gear 8 drives two limit bars 7 to move horizontally, thus horizontally inserting them into the soil.
[0019] In a further optimized design, the drive assembly includes a third receiving slot 15 formed in the platform body 1. The top of the control column 13 passes through the third receiving slot 15 and is located at the top of the platform body 1. A control gear 16 is rotatably connected to the control column 13 within the third receiving slot 15. The control gear 16 is arranged one-to-one with the control column 13, and the control column 13 slides through the control gear 16. A slider adapted to the vertical groove 14 is provided within the control gear 16, and the slider slides within the vertical groove 14. A rack 17 is slidably connected within the third receiving slot 15, and several control gears 16 mesh with the rack 17. A telescopic electric cylinder 18 is fixedly connected within the third receiving slot 15, and the output end of the telescopic electric cylinder 18 is fixedly connected to the rack 17. The telescopic electric cylinder 18 drives the rack 17 to move, thereby mobilizing all the control gears 16 to rotate. The control gears 16 can rotate the control column 13 without interfering with its up-and-down sliding, thus controlling the control column 13.
[0020] The scheme is further optimized by providing a vertically arranged limiting groove on the periphery of the limiting post 4, and a corresponding limiting protrusion on the platform body 1. Through the sliding cooperation between the limiting protrusion and the limiting groove, the limiting post 4 is restricted from relative rotation with the platform body 1, ensuring that when the threaded cylinder 9 rotates, the limiting post 4 can only move up and down along the axial direction.
[0021] To further optimize the design and facilitate the movement of the hoisting platform of this utility model, the bottom of the platform body 1 is fixedly connected with casters.
[0022] The working process of this utility model is as follows: The platform body 1 is transported to the designated position, and then the control motor 12 is started. The control motor drives the intermediate gear 11 to rotate, which in turn drives the transmission gear 10 to rotate. The transmission gear 10 drives the threaded cylinder 9 to rotate. Since the limiting column 4 slides with the platform body 1 along the axial direction, the limiting column 4 moves downward and extends out of the platform body 1 to insert into the ground (if the soil is hard, pre-drilled holes can be made in the ground beforehand). Then, the telescopic electric cylinder 18 is started. The telescopic electric cylinder 18 drives the rack 17 to move, which in turn drives all the control columns 13 to rotate. During the rotation of the control column 13, the drive gear 8 is driven to rotate, which in turn causes the two horizontally set limiting bars 7 to slide horizontally, so that they extend out of the opening and insert horizontally into the soil, increasing the stability of the limiting column 4. Then, the hoisting can be carried out.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
