[0002] With the transformation of the global energy structure towards clean energy, wind power generation, as one of the core renewable energy technologies, has witnessed a continuous and rapid growth in its installed capacity. As a key supporting structure of a wind turbine generator set, wind power tower barrels can be roughly divided into large wind power tower barrels or small wind power tower barrels according to different usage requirements. Among them, large wind power tower barrels are characterized by a large diameter (up to 6 - 12 meters), a high height (each section of the tower barrel is 20 - 40 meters long), and a heavy weight (the mass of each section exceeds 100 tons). Therefore, traditional hoisting methods face significant challenges in the transportation and installation of complex terrains (such as mountains and coastal beaches) or ultra-large tower barrels. In addition, with the diverse application environments of wind farms, higher requirements are put forward for the adaptability, safety, and efficiency of hoisting devices.

Specific embodiments

[0019] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

One end of the sling body 103 is in a closed ring structure and is sleeved with the transition ring plate 102; The top ends of two adjacent sling bodies 103 are fixed to form an arc-shaped structure, and a first pulley is sleeved outside the arc-shaped structure, and a lifting ring is fixed on the top of the first pulley, so as to facilitate the assembly with existing hoisting equipment while enhancing its own structural strength; The locking mechanism includes a hollow base 3, a plurality of Z-shaped hanging plates 4 are installed on the surface of the hollow base 3, and screw components 5 are installed between the inner tops of the plurality of Z-shaped hanging plates 4 and the corresponding threaded holes 2 of the wind power tower barrel 1, and the bottom of the sling component 10 is installed on the top of the corresponding Z-shaped hanging plate 4; The interior of the hollow base 3 is sleeved with an internally threaded seat 11, a first threaded rod 12, a camshaft member 13, and several safety rods 14. The camshaft member 13 is fixedly sleeved in the middle of the first threaded rod 12, and one end of the first threaded rod 12 is threadedly connected to the middle of the internally threaded seat 11. During the threaded connection process of the first threaded rod 12 and the internally threaded seat 11, the camshaft member 13 can synchronously press and drive several safety rods 14, so that one end of each of the several safety rods 14 extends into the step groove to limit the wind power tower barrel 1; The number of several Z-shaped hanging plates 4, the number of several sling components 10, and the number of several safety rods 14 are all the same and are all set to four; The surface of the camshaft member 13 is provided with four cams. The top of the first threaded rod 12 extends to the outside of the top of the hollow base 3 and is fixed with a steering wheel. Each of the four safety rods 14 includes a T-shaped safety rod 141, a limit block 142, and a return spring 143. The two ends of the T-shaped safety rod 141 are respectively located inside and outside the hollow base 3, and the middle of the T-shaped safety rod 141 is clamped and penetrates through the bottom structure of the corresponding Z-shaped hanging plate 4. The limit block 142 is fixed to the end of the T-shaped safety rod 141 located outside the hollow base 3. The return spring 143 is sleeved on the outside of one end of the T-shaped safety rod 141 located outside the hollow base 3, and the two ends of the return spring 143 are respectively fixed to the surface of the limit block 142 and the bottom surface of the corresponding Z-shaped hanging plate 4. The surfaces of the two ends of the T-shaped safety rod 141 are both arc-shaped structures.

[0021] During use, for the hoisting and assembly requirements of the wind power tower barrel 1, the hollow base 3, four Z-shaped hanging plates 4 and related structures are used for cooperation operations, as follows: The hollow base 3 and the four Z-shaped hanging plates 4 arranged on the surface of the hollow base 3 are sleeved with the open port at the top of the wind power tower barrel 1, and the chutes 15 at the tops of the four Z-shaped hanging plates 4 are aligned with the corresponding four threaded holes 2 on the top of the wind power tower barrel 1 one by one. After completion, the screw member 5 is used to penetrate the chute 15 and is screwed and locked with the corresponding threaded hole 2 to mechanically lock and fix the Z-shaped hanging plate 4 and the wind power tower barrel 1. The subsequent remaining three Z-shaped hanging plates 4 are also operated according to the above steps; After the four Z-shaped hanging plates 4 are stably connected to the top of the wind power tower barrel 1, considering the extremely small probability of the locking failure objectively existing and the direct dropping of the wind power tower barrel 1, turn the steering wheel at the top of the first threaded rod 12, and then use the steering wheel to drive the first threaded rod 12 and the camshaft member 13 to rotate synchronously, and the first threaded rod 12 and the internally threaded seat 11 are screwed and locked synchronously; During the rotation process, the camshaft member 13 will synchronously press the T-shaped safety rods 141 inside the four safety rod members 14 by means of the four cams provided on itself. Subsequently, the four T-shaped safety rods 141 will drive the corresponding limit blocks 142 to extend into the step grooves at the top of the wind power tower barrel 1 for limit clamping. The return springs 143 will expand and deform synchronously to make way. Thus, the falling trend of the wind power tower barrel 1 is restricted by the four limit blocks 142, and the probability of the direct drop of the wind power tower barrel 1 is reduced to the greatest extent. After the hollow base 3 and the related structures of the hollow base 3 are locked and assembled with the wind power tower barrel 1, the existing lifting equipment is assembled with the lifting rings connected in pairs of the four sling members 10. Then, the lifting equipment drives the hollow base 3, the four Z-shaped hanging plates 4, the wind power tower barrel 1 and the related structures to move up and down automatically through the four sling members 10. After the wind power tower barrel 1 reaches the designated position and is connected to the related existing structures, such as the wind power base, the screws installed between the four Z-shaped hanging plates 4 and the wind power tower barrel 1 are disassembled, and the first threaded rod 12 and the camshaft member 13 are rotated back. The four T-shaped safety rods 141 and the limit blocks 142 are automatically released from the limit effect under the return elastic force of the corresponding return springs 143. After completion, the hollow base 3, the four Z-shaped hanging plates 4 and the related structures are directly lifted by the existing lifting equipment to make way. Subsequently, according to the above steps, the operation can be repeated.

[0022] Please refer to Figure 5 . The screw components 5 are also set to four. Chute grooves 15 are provided at the tops of the four Z-shaped hanging plates 4. The four screw components 5 each include a screw body 51 and an annular gasket 52. One end of the screw body 51 can detachably assemble the Z-shaped hanging plate 4 and the wind power tower barrel 1 in a way that it passes through the middle of the annular gasket 52, the chute groove 15 and then is spirally locked with the corresponding threaded hole 2. An annular sleeve plate 53 is sleeved outside the nut at the top of the screw body 51 through a bearing. A spring strip 54 is installed between the surface of the annular sleeve plate 53 and the top surface of the corresponding Z-shaped hanging plate 4. A damping sheet 55 is sleeved outside the annular gasket 52, and the top surface of the damping sheet 55 is in contact with the bottom surface of the annular sleeve plate 53.

[0023] During use, considering the vibration influence suffered by the screw component 5 in the locked state and the loss problem after high-altitude disassembly, the provided annular sleeve plate 53 and spring strip 54 are used as auxiliary supports, and the bearing is used as the transition connection condition. Subsequently, while not interfering with the rotation and locking of the screw body 51, when the screw body 51 and the corresponding threaded hole 2 are locked and jointly bear pressure, the spring strip 54 and the damping sheet 55 are linked to perform damping buffering on the screw body 51.

[0024] Please refer to Figures 1-3 、 Figure 9, wind resistance mechanisms are provided between each of the four Z-shaped hanging plates 4 and the surface of the wind power tower barrel 1. The wind resistance mechanism includes an annular plate component 6, a positioning frame 7, a pulley component 8, and a limiting rope 9. The annular plate component 6 is sleeved outside the wind power tower barrel 1, and a number of self-adaptive clamps are sleeved along the circumferential direction inside the annular plate component 6. Each of the number of self-adaptive clamps includes a clamping plate 16 and a second threaded rod 17. Folding spring pieces 18 are installed between the surfaces at both ends of the clamping plate 16 and the inner wall of the annular plate component 6. One end of the second threaded rod 17 is threadedly connected to the inner side of the middle part of the annular plate component 6 and can perform a pressing drive on the corresponding clamping plate 16, so that two clamping plates 16 in relative positions clamp and limit the wind power tower barrel 1; The positioning frame 7 is installed on the top of the annular plate component 6, the pulley component 8 is installed on the top of the corresponding Z-shaped hanging plate 4, one end of the limiting rope 9 is fixed to the top of the positioning frame 7, and the other end of the limiting rope 9 is wound and sleeved on the inner pulley of the pulley component 8 and extends to the outside of the wind power tower barrel 1. The inner wall of the clamping plate 16 is an arc surface that can fit the surface of the wind power tower barrel 1, and a handle is fixed to the end of the second threaded rod 17 away from the annular plate component 6.

[0025] During use, considering the inclination problem caused by the impact of the rapidly flowing air in the environment on the wind power tower barrel 1 during the lifting process, when the wind power tower barrel 1 is lifted by the existing lifting equipment after being locked by the hollow base 3, the four Z-shaped hanging plates 4 and related structures, four workers are arranged on the ground to hold the ends of the four limiting ropes 9 away from the wind power tower barrel 1 respectively and stand in four directions. During the gradual ascent of the wind power tower barrel 1, the limiting ropes 9 are synchronously released in a traction and stretching manner until the wind power tower barrel 1 reaches the highest point, thereby ensuring the stability of the wind power tower barrel 1 during the lifting process; When a strong wind suddenly appears during the lifting process, depending on the wind speed, if the wind speed is average, the four workers can increase the traction force to enhance the wind resistance ability of the wind power tower barrel 1, so that the wind power tower barrel 1 is lifted and assembled in a relatively stable state. If the wind speed is relatively high and it is difficult to maintain manually, the lifting is stopped, and the ends of the four limiting ropes 9 away from the wind power tower barrel 1 are tied and fixed to four long screws in sequence. Then, the four long screws are driven into the ground to fully enhance the wind resistance ability of the wind power tower barrel 1, and the lifting and assembly are continued after the subsequent wind force weakens or stops; Secondly, during further use, when the space is narrow, large-scale lifting equipment cannot be used, and a small wind power tower is installed, a stable support, such as a scaffolding, can be set at the specific installation position. Then, two lifting rings are fixed to the top of the support. After completion, the annular plate component 6 is sleeved on the middle part of the small wind power tower. Then, the four second threaded rods 17 are rotated in sequence, and then the four second threaded rods 17 press their respective corresponding clamping plates 16 under the spiral meshing support of the annular plate component 6, so that two groups of two relatively opposed clamping plates 16 clamp and limit the small wind power tower; After the small wind power tower barrel is stably clamped, four workers are arranged on the ground to hold one end of each of the four limiting ropes 9 and move away from the bracket in four directions at a relatively same speed. Then, by using the pulley rolling effects of the four pulley components 8 and the four limiting ropes 9 which are in one-to-one correspondence, the four positioning frames 7 drive the ring plate component 6, as well as the four clamping plates 16, the four second threaded rods 17 and the wind power tower barrel 1 clamped inside the ring plate component 6 to perform an automatic ascending operation, meeting the operation requirements for assembling the wind power tower barrel 1 in harsh environments. Similarly, for a larger wind power tower barrel 1, the alternating use of the clamping and limiting of the ring plate component 6 and the components inside the ring plate component 6 and the locking mechanism can also perform a small-gap adjustment under manual control for the wind power tower barrel 1 in the assembled state.

[0026] Please refer to Figures 1-3 , the ring plate component 6 is composed of two symmetrical semi-circular plate bodies 61, and a bolt locking component 62 is provided at the end connection of the two semi-circular plate bodies 61. The bolt locking component 62 includes a bolt and a nut; Relieving holes are respectively opened at both ends of the two semi-circular plate bodies 61. One end of the bolt passes through the two relieving holes at the relative positions at the end connection of the two semi-circular plate bodies 61 and then the two semi-circular plate bodies 61 are detachably installed in a way that the nut is screwed and locked.

[0027] During use, in view of the problem that it is inconvenient to replace and disassemble the four second threaded rods 17 at multiple high-altitude positions, the ring plate component 6 is set as two semi-circular plate bodies 61. Through the assembling structure of multiple bolt locking components 62, after the ring plate component 6 and the internal structure of the ring plate component 6 are used up, only the bolt locking components 62 at two positions need to be disassembled, and then the ring plate component 6 can be separated from the surface of the wind power tower barrel 1.

[0028] Please refer to Figure 4 , an installation space is provided at the bottom of the hollow base 3. An inclination sensor 19, a controller component 20 and a multi-axis gyroscope 21 are sleeved in the installation space. Both the inclination sensor 19 and the multi-axis gyroscope 21 are electrically connected to the controller component 20 through wires. The controller component 20 includes a processor, a wireless transmission module, an alarm and a battery module. A plurality of ventilation holes communicating with its own space are opened in the bottom structure of the hollow base 3, and protective filters are nested in the ventilation holes.

[0029] During use, the inclination sensor 19 and the multi-axis gyroscope 21 can wirelessly transmit the real-time position state of the wind power tower barrel 1 during the hoisting process to the control background on the ground. And when the real-time position state of the wind power tower barrel 1 during the hoisting process exceeds the preset data value, the alarm will give an alarm, prompting the staff to suspend the hoisting or adjust the wind power tower barrel 1 by the four limiting ropes 9.
