[0002] A wind turbine is a device that converts wind energy into electrical energy. It has been widely used around the world and has become an important force in promoting the development of green energy. A wind turbine usually consists of key parts such as a wind rotor, a generator, a tower, and a control system. The wind rotor captures wind energy and drives the generator to rotate through a mechanical transmission device, thereby converting wind energy into electrical energy. The control system is responsible for monitoring and adjusting the operating status of the wind turbine to ensure its efficient and stable operation. The tower plays a supporting role.

[0003] The existing tower is composed of multiple tower sections connected by high-strength bolts. During the tower connection process, the tower needs to be hoisted by a large crane. When the tower is hoisted to the top of the bottom tower, the tower is manually towed and guided so that the bolt holes of the two tower sections correspond to each other and are bolted together. However, in the actual operation process, due to the large volume of the tower and the strong wind in the wind power generation area, the tower will shake significantly during the docking process, which will make it difficult for workers to connect the tower and is not conducive to the docking of the tower.

A plurality of transmission rods 19 are fixedly connected to one side of a rectangular plate 20. A second extrusion groove 21 is provided on each of the plurality of rectangular plates 20. The second extrusion groove 21 is sleeved on the second extrusion shaft 15, and the second extrusion groove 21 is slidably connected to the second extrusion shaft 15. A second reinforcing rib 22 is fixedly connected to one side of the bottom end of each of the transmission rods 19, and the second reinforcing rib 22 is fixedly connected to the rectangular plate 20. A plurality of transmission rods 19 are fixedly connected to the top of each of the second circular shafts 23, and a plurality of rubber rollers 24 are rotatably connected to both ends of the plurality of second circular shafts 23.

[0018] Specifically, one end of the screw rod 6 is fixedly connected to an adjusting disk 25 , and the adjusting disk 25 is designed as an anti-slip structure, so that the screw rod 6 can be rotated through the adjusting disk 25 to enable the screw rod 6 to transmit the power to the slider 7 .

[0019] Specifically, a threaded sleeve is fixedly connected to the center of the top of the transmission plate 13 , and a lifting ring 26 is connected to the inner thread of the threaded sleeve, so that the device can be lifted through the lifting ring 26 .

[0020] Specifically, a rubber layer 27 is fixedly connected to one side of several top plates 4, and one side of the rubber layer 27 is designed with an anti-slip structure. The top plates 4 and the rubber layer 27 are both designed with arc structures, which facilitates the top plates 4 and the rubber layer 27 to fit with the inner wall of the tower and support the inner wall of the tower.

[0021] Specifically, the base 1 is designed as a fan-shaped structure, and the cross-section of the storage groove 2 is convex, which is convenient for leaving space for workers to operate, and at the same time, it is convenient for the storage groove 2 to store the electric telescopic rod 3 and the top plate 4.

[0022] Specifically, the slider 7 is designed as a rectangular structure, and the top of the slider 7 fits with the bottom of the transmission disk 10 , so that the slider 7 can be limited by the transmission disk 10 .

[0023] Specifically, the first reinforcing rib 5 and the second reinforcing rib 22 are both designed in a triangular structure, and the first reinforcing rib 5 and the second reinforcing rib 22 are both designed in a hollow structure, which is convenient for increasing the connection strength between the electric telescopic rod 3 and the top plate, and at the same time, it is convenient to increase the connection strength between the transmission rod 19 and the rectangular plate.

[0024] When in use, the base 1 is hoisted by a crane and placed at the center of the top of the first section of the tower, and the electric telescopic rod 3 is started. The output end of the electric telescopic rod 3 drives the top plate 4 and the rubber layer 27 to squeeze the inner wall of the tower. The position of the base 1 is fixed by squeezing several top plates 4. At this time, the second section of the tower is hoisted to the top of the first section of the tower, 50 cm away from the first section of the tower. At this time, the rubber roller 24 is located at the top position of the sealing surface of the second section of the tower. After the sealing surface sealant is applied, the hydraulic cylinder 12 is started, and the output end of the hydraulic cylinder 12 drives the transmission plate 13 to move upward. The transmission plate 13 drives the transmission frame 14 to move, and the moving transmission frame 14 squeezes the second squeezing groove 21 provided on the rectangular plate 20 through the second squeezing shaft 15. The squeezed rectangular plate 20 then drives the transmission rod 19 to move around the first circular shaft 18. The moving transmission rod 19 then drives the rubber roller 24 to squeeze the second section of the tower through the second circular shaft 23. Several rubber rollers 24 squeeze the second section of the tower at the same time. Since the axis of the annular tracks of the several rubber rollers 24 corresponds to the axis of the base 1, and the axis of the base 1 corresponds to the axis of the first section of the tower Therefore, the axis of the squeezed second section of the tower corresponds to the axis of the first section of the tower. At this time, the second section of the tower is lowered by a crane, and the inner wall of the second section of the tower squeezes the rubber roller 24, so that the rubber roller 24 rotates while guiding and positioning the second section of the tower. When the second section of the tower shakes, the rubber roller 24 can buffer the impact of the shaking, so that the axis of the second section of the tower always corresponds to the axis of the first section of the tower. When the sealing surface of the second section of the tower fits with the sealing surface of the first section of the tower, the screw rod 6 is rotated by the adjusting disk 25, and the screw rod 6 then drives The movable slider 7 moves, and the moving slider 7 drives the first extrusion shaft 8 to extrude the first extrusion groove 11 provided on the transmission plate 10. The extruded transmission plate 10 is then rotated through the transmission shaft 9. The rotating transmission plate 10 drives the support frame 17, the first circular shaft 18, the transmission rod 19, the second circular shaft 23 and the rubber roller 24 to rotate through the bottom plate 16. Since the rubber roller 24 fits the inner wall of the second tower, the rotating rubber roller 24 drives the second tower to rotate, so as to adjust the bolt holes provided on the sealing surface of the second tower to be aligned with the bolt holes on the sealing surface of the first tower.
