[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] A modular lifting device for installing wind turbine towers, such as Figures 1 to 3As shown, the assembly includes a lifting device body 1 and a combined body 3. The lifting device body 1 has an assembly groove 2 at the bottom that can mate with the wind turbine tower connecting plate, and a connector 12 at the top. Two connectors 12 are provided on the left and right sides of the lifting device body 1, and there is an assembly gap between the two connectors 12. The lifting device body 1 has a detachable plug-in part 13 at the position corresponding to the assembly gap, and the plug-in part 13 is provided with bolt holes on the wind turbine tower connecting plate. The combined body 3 includes a connecting section 5 and a clamping section 7. There is a clamping gap between the clamping section 7 of the combined body 3 and the lifting device body 1, which mates with the wind turbine tower body. The clamping gap is connected to the assembly groove 2. The connecting section 5 of the combined body 3 extends into the assembly gap and has a lifting component 4 and a plug-in hole 15. The plug-in hole 15 is provided with the plug-in part 13. The lifting component 4 and the plug-in hole 15 are offset. The lifting component 4, the connector 12 and the connecting section 5 of the combined body 3 are rotatably connected.

[0027] Preferably, the lifting component 4, the connecting component 12, and the connecting section 5 of the assembly 3 are rotatably connected by a rotating shaft 6. Each of the lifting component 4, the connecting component 12, and the connecting section 5 of the assembly 3 is provided with a shaft hole 17 for mounting the rotating shaft 6. The connecting component 12 can be fixed to the lifting device body 1 by conventional methods such as welding, and the rotating shaft 6 can also be mounted on the shaft hole 17 by conventional methods such as locating pins, thus achieving a stable rotatable connection between the lifting component 4, the connecting component 12, and the connecting section 5 of the assembly 3. Those skilled in the art can also choose other installation methods to install the rotating shaft 6 according to actual needs, which will not be elaborated here.

[0028] In practical applications, the lifting device body 1 is provided with an assembly hole 16 on its upper part, which mates with the connector 13. The assembly hole 16 is connected to the assembly groove 2. Specifically, one end of the assembly hole 16 is connected to the assembly gap, and the other end is connected to the assembly groove 2. The connector 13 can pass through the connector hole 15, and then through the assembly hole 16 and the bolt hole in sequence to achieve a stable connection between the assembly 3, the lifting device body 1, and the wind turbine tower connecting plate, ensuring that the lifting device is not easily separated from the wind turbine tower during the lifting process.

[0029] When hoisting a wind turbine tower, operators can clamp and fix the tower by rotating the assembly 3 and the lifting device body 1. Then, by installing the connector 13 onto the lifting device body 1, with one end of the connector 13 inserted into the bolt hole on the connecting plate and the other end inserted into the connector hole 15 of the connecting section 5 of the assembly 3, the relative positions of the assembly 3 and the lifting device body 1 are fixed. At this point, the mounting groove 2 on the lifting device body 1 stably engages with the connecting plate of the wind turbine tower, improving the stability of the tower during subsequent hoisting and simplifying the operation. Conversely, once the wind turbine tower is in place, operators only need to remove the connector 13, rotate the assembly 3, and move the lifting device body 1 to dismantle the lifting device.

[0030] Preferably, the end of the connector 13 extending out of the connector hole 15 is provided with a lifting lug 14. Exemplarily, the lifting lug 14 can be fixed to the connector 13 by conventional methods such as welding. By providing the lifting lug 14, it is easier for operators to load and unload the connector 13, which helps reduce the difficulty of loading and unloading the connector 13 during high-altitude operations. Furthermore, the lifting lug 14 can be used to connect ropes, allowing operators to manually assemble or remove the connector 13, which helps reduce the difficulty of using this lifting tool and improves its applicability to different construction environments.

[0031] Preferably, the end of the connector 13 that extends into the bolt hole of the wind turbine tower connecting plate has a tapered end. By providing the tapered end, it is easier for operators to assemble the connector 13.

[0032] Preferably, the lifting component 4 has a limiting part 9 on the side facing the insertion hole 15 to limit the movement of the insertion component 13. By setting the limiting part 9 to limit the insertion component 13, the probability of the insertion component 13 falling off during the hoisting of the wind turbine tower can be reduced.

[0033] In practical applications, to improve the stability of wind turbine tower hoisting, multiple lifting devices are often evenly arranged around the circumference of the wind turbine tower. These devices, including hooks and ropes, are then used to connect the lifting components 4 to the lifting devices, thus achieving stable hoisting of the wind turbine tower. The lifting components 4 are generally tilted towards the center of the wind turbine tower. At this point, the limiting part 9 on the lifting device can block and limit the insertion connector 13, preventing it from detaching. After hoisting is completed, the operator can easily disassemble the insertion connector 13 by rotating the lifting device 4 to release the limiting effect. The operation is very simple.

[0034] Preferably, the connector 12 is connected to the lifting device body 1 by a reinforcing plate 8. For example, one or more reinforcing plates 8 may be provided, each reinforcing plate 8 having one end welded and fixed to the lifting device body 1 and the other end welded and fixed to the connector 12. By providing the reinforcing plate 8, the structural strength at the connection between the connector 12 and the lifting device body 1 is improved, thereby ensuring a stable connection between the lifting component 4 and the lifting device body 1, and between the assembly and the lifting device body 1.

[0035] Preferably, a reinforcing member 10 is provided on the assembly 3 at the position corresponding to the connection between the connecting segment 5 and the clamping segment 7. One end of the reinforcing member 10 is connected to the connecting segment 5, and the other end is connected to the clamping segment 7. For example, the reinforcing member 10 can be fixed to the assembly 3 by conventional methods such as welding. By setting the reinforcing member 10 at the connection between the connecting segment 5 and the clamping segment 7, it is beneficial to improve the structural strength of the assembly 3.

[0036] In practical applications, the connecting section 5 and the clamping section 7 of the assembly 3 can be set at a certain angle, such as 90 degrees, to better fit with the edge of the wind turbine tower. In addition, the clamping section 7 can also be provided with a fitting part that can fit with the wall of the wind turbine tower, such as an inclined surface, which helps to improve the clamping effect of the assembly 3 and the lifting body 1 on the end of the wind turbine sleeve.

[0037] Preferably, the reinforcing member 10 is provided with a through hole 11 for installing a traction rope. By providing a traction rope, the operator can use the traction rope to drive the assembly 3 to rotate, thereby assembling the lifting device.

[0038] This utility model discloses a modular lifting device for wind turbine tower installation, which has the advantages of simple structure, stability and reliability, and ease of assembly and use. It can be used for the lifting operation of wind turbine towers and is very convenient to disassemble, reducing the difficulty of high-altitude operations for operators and improving the subsequent lifting efficiency of wind turbine towers. By setting detachable connectors on the lifting device body, the relative positions of the lifting device body, wind turbine sleeve, and assembly can be fixed using the connectors, which is simple to operate and helps to improve the stability of the wind turbine tower during subsequent lifting processes.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
