[0023] Specifically, the base 1 serves as the supporting part of the lifting platform, which ensures that the platform can stand stably on the ground or the installation position. The crane component 2 is installed on the top of the base 1. The main function of the crane component 2 is to bear, lift and rotate the hook component 3. The hook component 3 is suspended and carried by the crane component 2. The hook component 3 is used to carry and lift various components or tools in the tower foundation. The buckle component 4 is arranged inside the hook component 3, which can accurately fix the four fixed seats 306 and ensure the stability of the fixed seats 306 to prevent displacement or instability during the lifting process. The telescopic component 5 is arranged inside the hook component 3. The main function is to perform telescopic operations on the protective component 6. The protective component 6 can provide protection for the ground workers during the lifting process to prevent the gravel or other impurities on the construction site from adhering to the hoisted object. The telescopic component 5 adjusts the telescopic length of the protective component 6 through a hydraulic system or mechanical transmission to meet the needs of different lifting tasks.

[0024] Please see attached Figure 2 and attached Figure 4 The hook assembly 3 includes a mounting seat 301, and the left and right sides of the bottom end of the mounting seat 301 are fixedly connected to the mounting frame 302, the bottom end of the mounting frame 302 is provided with a strap 303, the upper side of the mounting seat 301 is fixedly connected to the fixing frame 304, the left and right sides of the bottom end of the fixing frame 304 are rotatably connected to the balancing wheel 305, the front and rear sides of the balancing wheel 305 are connected to the fixing seat 306 through steel ropes, the inside of the mounting seat 301 is slidably connected to the outside of the fixing seat 306, and the fixing seat 306 is connected to the reserved hole of the wind power tower body through bolts.

[0025] Specifically, the mounting base 301 serves as the basis of the entire hook assembly 3, providing support and stability.

The fixing base 306 is connected to the front and rear sides of the balance wheel 305 through a steel rope. The friction of the fixing base 306 during use is reduced by rotation, ensuring that the fixing base 306 maintains an appropriate height and position during operation. It is connected to the reserved holes of the wind turbine tower body through bolts to ensure that the fixing base 306 can be firmly fixed on the wind turbine tower body to ensure safety and stability.

[0026] Please see attached Figure 1 and attached Figure 3The crane assembly 2 includes a standard section 201, which is fixedly connected to the top of the base 1. An outer tower body 202 is arranged outside the standard section 201. The top of the outer tower body 202 is rotatably connected to a load-bearing seat 203. A cab 204 is installed outside the load-bearing seat 203. An outer peripheral sleeve 205 is rotatably connected to the outer side of the load-bearing seat 203.

[0027] Specifically, the standard section 201 serves as the main structure of the crane, providing necessary support and stability. The outer tower body 202 extends the height of the standard section 201 to form the tower body part of the crane, thereby enhancing the working height and operating range of the crane. The load-bearing seat 203 serves as the load-bearing structure of the crane, capable of bearing the weight of the hoisted object and distributing it to the tower body and the foundation. The cab 204 is provided for the operator to control the operation of the crane to ensure the normal operation and safety of the crane. The outer sleeve 205 increases the structural stability of the crane and provides additional support points. The fixed pulley 206 reduces friction by changing the direction of the hoisting rope 207 to enhance the lifting capacity of the crane. The connector 208 serves as the connection point between the hoisting rope 207 and the load to ensure a firm connection of the hoisted object.

[0029] Specifically, there is a limit groove 401 on each of the front and rear sides of the mounting seat 301, which provides a sliding path for the limit block 403 and limits its range of motion to prevent it from exceeding the set working position. It can slide freely in the limit groove 401 and adjust its position by pulling the pull rope 406. One end of a spring 402 is fixed to the outside of the limit block 403, and the other end is fixed to the inner wall of the limit groove 401, so that the spring 402 can provide a stable restoring force to ensure that the limit block 403 can return to its original position after being pulled, thereby achieving automatic resetting, and then the rotation of the rotating rod 407 can drive the pull ropes 406 on both sides to move. Slots 405 are provided on the front and rear sides of the fixing seat 306, and the outside of the block 404 is engaged with the inside of the slot 405 to prevent the fixing seat 306 from accidental displacement during use.

The design of the front and rear sides can provide better stability and balance. The connecting frame 502 plays a role of connection and support. The electric push rod 2 503 is responsible for the telescopic action, and its telescopic action drives the locking wheel 504 to extend. Through the locking wheel 504, the hook 601 can be prevented from accidentally falling off when subjected to force, and the length of the hook 601 can be controlled.

[0032] Please see attached Figure 5 and attached Figure 6 The protective component 6 includes four hooks 601, and the four hooks 601 are respectively wrapped around the outside of the four locking wheels 504. The lower side of the hook 601 is rotatably connected with a baffle 602, and the baffle 602 abuts against the end of the hook 601.
