[0071] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0072] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0073] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the installation equipment 200 and installation method of the wind turbine generator set 100 of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0074] To better understand this application, the installation equipment 200 and installation method of the wind turbine generator set 100 according to the embodiments of this application will be described in detail below with reference to Figures 1 to 52.

[0075] Please refer to Figure 1, which is a structural schematic diagram of a wind turbine generator set 100 according to an embodiment of this application.

[0076] The wind turbine generator set 100 includes a foundation platform 10, a tower 20, and multiple wind turbine components. The tower 20 is typically of two or more sections, comprising multiple tower sections 210 arranged sequentially along a first direction Z and connected at their ends. The lower tower section 210 is connected to the foundation platform 10. The multiple wind turbine components include a nacelle 30 and an impeller. The nacelle 30 is connected to the upper tower section 210, and a generator may be installed inside the nacelle 30. The impeller includes a hub 40 and multiple blades 50 connected to the hub 40. The impeller is connected to the generator shaft through its hub 40. When wind power acts on the blades 50, it drives the entire impeller and the generator shaft to rotate, converting wind energy into electrical energy.

[0077] Referring to Figure 31, in the prior art, the installation of a wind turbine generator set 100 requires multiple tower sections 210 and turbine components to be hoisted to a preset height and spliced ​​using a crane 300. However, as the weight and size of the tower sections 210 and turbine components increase, the performance requirements of the crane 300 also increase. Large-tonnage cranes 300 are not only scarce and costly, but also suffer from low installation efficiency, large operating radius, and large footprint. Therefore, to overcome these shortcomings, this application provides an installation device 200 and an installation method for a wind turbine generator set 100. The installation device 200 can be used for the installation of wind turbine generator sets 100 of various specifications.

[0078] Please refer to Figure 2, which shows a schematic diagram of the installation device 200 in an embodiment of this application.

[0079] This application provides an installation device 200, which includes a lifting base 1, a tooling body 2, and a lifting device body 3. The lifting base 1 is connected to the outer wall of the tower section 210. The tooling body 2 includes an installation platform 21 and a first power device 22 disposed on the installation platform 21. The first power device 22 includes a first drive member 221 and a first traction cable 222. The first traction cable 222 is connected to the lifting base 1. The first drive member 221 is used to retract and extend the first traction cable 222 and to raise and lower the installation platform 21 along the first direction Z. The lifting device body 3 is connected to the installation platform 21 and can move with the installation platform 21. The lifting device body 3 is used to clamp one of the tower sections 210 or the wind turbine component, so that one of the tower sections 210 is installed on the other tower section 210 or the wind turbine component is installed on the tower frame 20.

[0080] It is understandable that, taking the tower 20 as an example, which includes a first tower section 210a and a second tower section 210b arranged along the first direction Z, when hoisting the second tower section 210b, the lifting seat 1 on the first tower section 210a can be connected to the first traction cable 222. The first power device 22 drives the installation platform 21 to rise to the height of the first tower section 210a, and then the second tower section 210b is installed on the first tower section 210a through the lifting body 3 of the installation platform 21, thus forming the tower 20. The above embodiment is based on the tower 20 including two tower sections 210. Of course, the tower 20 may also include three, four, or even more tower sections 210. When assembling the tower 20, during the hoisting of the subsequent tower section 210, the first traction cable 222 can be connected to the lifting seat 1 of the preceding tower section 210 to raise the installation platform 21 to the height of the preceding tower section 210, and then the subsequent tower section 210 can be installed on the preceding tower section 210. Repeating the above process will complete the installation of the tower 20. However, for ease of description, the following description will still take the tower 20 including the first tower section 210a and the second tower section 210b as an example.

[0081] When hoisting the wind turbine components, the lifting seat 1 on the second tower section 210b is connected to the first traction cable 222. The first power unit 22 drives the installation platform 21 to rise to the height of the second tower section 210b. Then, the wind turbine components are hoisted onto the second tower section 210b by the lifting body 3 of the installation platform 21, thereby realizing the installation of the wind turbine generator set 100.

[0082] The installation equipment 200 in this embodiment can use the lifting base 1 as a lifting point to raise the installation platform 21 to the height of the tower section 210, so that the subsequent lifting of the tower section 210 and / or wind turbine components can be achieved through the lifting body 3 on the installation platform 21. Using the above-mentioned installation equipment 200 can improve installation efficiency and reduce the lifting height required by the lifting body 3 itself, thereby reducing the performance requirements of the lifting body 3 and overcoming the bottleneck of the wind turbine generator set 100 developing towards higher towers 20 and larger capacities. At the same time, it can also reduce the platform area required for the installation of the wind turbine generator set 100, giving it a wider range of application prospects.

[0083] To facilitate understanding of the technical solution of this application, the structures of the lifting base 1, tooling body 2, and lifting device body 3 of the installation equipment 200 will be described in detail below.

[0084] In some alternative embodiments, the lifting seat 1 is detachably connected to the tower section 210, so that after the second tower section 210b is installed, the lifting seat 1 can be removed from the first tower section 210a and connected to the second tower section 210b, so that the lifting seat 1 on the second tower section 210b can be used as a lifting point to realize the lifting and lowering of the installation platform 21. By detachably connecting the lifting seat 1 to the tower section 210, the reliability of the lifting can be improved, and the number of lifting seats 1 can be reduced, thus reducing costs. It is understood that in some other embodiments, the lifting seat 1 can also be fixed to the tower section 210. For example, the lifting seat 1 can be directly welded to at least a portion of the tower section 210 and connected to the corresponding lifting seat 1 on the tower section 210 through the first traction cable 222, so as to realize the lifting and lowering of the installation platform 21 as a lifting point.

[0085] Please refer to Figures 2 to 5. Figure 3 shows a structural schematic diagram of the tower section 210 provided in the embodiment of this application. Figure 4 shows a partial enlarged view of the upper hanger 1 of the tower section 210 provided in the embodiment of this application. Figure 5 shows a partial enlarged view of the tower section 210 provided in the embodiment of this application with the hanger 1 omitted.

[0086] To facilitate the detachable connection of the mounting bracket 1 to the tower section 210, in some optional embodiments, the installation device 200 further includes a mounting bracket hoist 4 and a connector. The mounting bracket hoist 4 is connected to at least one tower section 210. The mounting bracket hoist 4 is used to drive the mounting bracket 1 to move along the first direction Z to the mounting bracket installation position 220 on the tower section 210, and to detachably connect the mounting bracket 1 to the mounting bracket installation position 220 via the connector.

[0087] By installing a hoist 4 on the tower section 210, the hoist 1 can be moved to the hoist installation position 220 on the tower section 210, or lowered to a designated position after the hoist 1 has been removed, thus achieving the installation of the hoist 1 without the need for manual lifting of the hoist 1, reducing the installation difficulty. Optionally, the hoist 1 and the hoist installation position 220 on the tower section 210 can be provided with corresponding connecting holes, and the connecting parts can be bolts. When the connecting hole on the hoist 1 is aligned with the connecting hole of the hoist installation position 220, the connecting parts can be sequentially passed through the tower section 210 and the hoist 1 from inside the tower section 210, and the hoist 1 can be connected to the hoist installation position 220.

[0088] Optionally, the hoist 4 can be detachably connected to at least one tower section 210, thereby reducing the number of hoists 4 and lowering costs.

[0089] Optionally, the mounting position 220 of the tower section 210 can be at least partially protruding from the outer wall of the tower section 210. The mounting base 1 is provided with a guide groove 11 along the first direction Z. The guide groove 11 is gradually narrowed along the direction away from the mounting base hoist 4, so as to play a guiding role and make it easier to move the mounting base 1 along the first direction Z to the mounting position 220 on the tower section 210 by the mounting base hoist 4.

[0090] In some alternative embodiments, the hoist 4 includes a hoist mounting base 41, a second drive member 42, and a second traction cable 43 disposed at the output end of the second drive member 42. The second drive member 42 is connected to the inner wall of at least one of the tower sections 210 through the hoist mounting base 41, and the second traction cable 43 is connected to the hoist 1 installed on the outer wall of the tower section 210 through a communication port 230 on the tower section 210.

[0091] By detachably connecting the hoist mounting base 41 to the hoist mounting position 240 on the inner wall of the tower section 210, it is easier for workers to disassemble and assemble the hoist 4 from inside the tower section 210, reducing the difficulty of disassembly and assembly.

[0092] Optionally, the hoist mounting base 41 can be fixed to the hoist mounting position 240 by bolts. The second drive component 42 includes a second drive motor, a second coupling, and a second winch. The second drive motor can be a standard component and is connected to the base of the hoist 4 by bolts to provide power to the entire hoist 4. The second coupling is used to connect the second drive motor and the second winch, realizing the purpose of transmitting the power output of the second drive motor to the second winch. The second winch is mounted on the base of the hoist 4, and a second traction cable 43 is wound on the second winch. The end of the second traction cable 43 is connected to the hoist 1. The second drive motor drives the second winch to rotate along its own axis, realizing the tightening or loosening of the second traction cable 43 mounted on the second winch.

[0093] Optionally, the second traction cable 43 may be a steel wire rope.

[0094] In some alternative embodiments, the hoist mounting position 240, the connecting port 230, and the hoist mounting position 220 are located on the same line, and the extension direction of the line is parallel to the first direction Z.

[0095] Since the installation of the jack 1 requires the jack hoist 4 to drive the jack 1 to move along the first direction Z, by making the jack hoist installation position 240, the connecting port 230 and the jack installation position 220 on the same line, and the extension direction of the connecting line is parallel to the first direction Z, it is easier to make the second traction cable 43 pass through the connecting port 230 and connect with the jack 1 installed on the outer wall of the tower section 210, so as to lift the jack 1 to the jack installation position 220 for fixing or lower the jack 1 to the designated position after removal.

[0096] Please refer to Figures 2 to 7. Figure 6 shows a schematic diagram of the connection between the installation platform 21 and the hanging base 1 provided in the embodiment of this application. Figure 7 shows a top view of the connection between the installation platform 21 and the hanging base 1 provided in the embodiment of this application.

[0097] For the tooling body 2, after connecting the lifting seat 1 to the tower section 210, the lifting seat 1 is used as a lifting point to raise the installation platform 21, so that the lifting body 3 on the installation platform 21 can be driven to the height of the tower section 210. In order to facilitate the lifting and lowering of the installation platform 21 relative to the tower section 210, in some optional embodiments, the installation platform 21 is provided with a first opening 211. The first opening 211 is concentrically arranged with the tower section 210. The installation platform 21 can be sleeved on the outer periphery of the tower section 210 through the first opening 211 and can be lifted and lowered relative to the tower section 210 in the first direction Z.

[0098] By setting a first opening 211 on the installation platform 21 and making the first opening 211 concentric with the tower section 210, the degree of freedom of movement of the installation platform 21 in other directions can be restricted by the tower section 210 during the hoisting process, thereby improving the reliability of lifting.

[0099] In some optional embodiments, the installation platform 21 is further provided with a plurality of first guide members 212, which are spaced apart circumferentially along the first opening 211 and protrude toward the first opening 211. By providing a plurality of first guide members 212 at circumferential intervals on the first opening 211, the first guide members 212 can abut against the outer wall surface of the tower section 210 during the lifting and lowering of the installation platform 21 relative to the tower section 210 in the first direction Z, thereby improving the stability of the installation platform 21 moving relative to the tower section 210 in the first direction Z, reducing the risk of the installation platform 21 scraping against the tower section 210, and improving the reliability of lifting and lowering.

[0100] Optionally, the diameter of the circular structure formed by the surfaces of the multiple first guide members 212 facing one side of the tower section 210 is larger than the diameter of the tower section 210. Thus, during the process of the installation platform 21 moving up and down relative to the tower section 210 in the first direction Z, if there is an eccentricity, the guide wheel will first contact the outer wall surface of the tower section 210, which reduces frictional resistance and also protects the paint surface of the tower section 210, thereby improving the service life of the wind turbine generator set 100.

[0101] Optionally, the first guide member 212 can be configured as a guide wheel, which is installed on the installation platform 21 and has a soft rubber structure on its surface. This avoids damage to the paint and body of the tower section 210 when the guide wheel contacts the outer wall surface of the tower section 210, thereby improving the service life of the wind turbine generator set 100.

[0102] Optionally, the number of first guide members 212 can be set to six, and the first guide members 212 are evenly distributed at 60° along the circumference of the first opening 211. Of course, the number of first guide members 212 can also be set to four, or more. The number of first guide members 212 can be adjusted according to the specific structure of the installation device 200, and this application does not make a specific limitation in this regard.

[0103] Please refer to Figures 2 to 8. Figure 8 shows a schematic diagram of the structure of the first power unit 22 provided in the embodiment of this application.

[0104] In some alternative embodiments, the lifting base 1 and the first power unit 22 are correspondingly arranged to form a lifting group, and the number of lifting groups is two or more and they are spaced apart circumferentially along the first opening 211.

[0105] Each lifting assembly includes a lifting base 1 and a first power unit 22. The first power unit 22 is mounted on the installation platform 21, and the lifting base 1 is connected to the tower section 210. The first traction cable 222 of the first power unit 22 is connected to the lifting base 1. When the first power unit 22 tightens the first traction cable 222, it causes the entire installation platform 21 and the lifting device body 3 on the installation platform 21 to rise relative to the tower section 210. When the first power unit 22 releases the first traction cable 222, it causes the entire installation platform 21 and the lifting device body 3 on the installation platform 21 to descend relative to the tower section 210. By arranging multiple lifting assemblies at circumferential intervals along the first opening 211, the installation platform 21 can be simultaneously lifted and lowered by multiple lifting assemblies, thereby improving the reliability of the lifting and lowering of the installation platform 21 and the lifting device body 3 on the installation platform 21.

[0106] Optionally, the number of lifting base groups 1 can be set to four, with the four lifting base groups 1 distributed at 90° intervals along the circumference of the first opening 211. That is, the installation equipment 200 includes four lifting bases 1 and four first power units 22. The first traction cable 222 of the first power unit 22 is connected to the lifting base 1 fixed on the tower section 210 respectively. By tightening or loosening the first traction cable 222, the installation platform 21 and the lifting body 3 on the installation platform 21 are driven to rise and fall. The first traction cable 222 can be set as a steel wire rope.

[0107] In addition, the lifting device hoist and the connecting port 230 on the tower section 210 can also be set to four, and the second traction cable 43 of the lifting device hoist is connected to the lifting device 1 through the corresponding connecting port 230, so that the lifting device 1 can be detachably connected to the tower section 210.

[0108] In some alternative embodiments, the first power unit 22 includes a first drive motor, a first coupling, and a first winch. The first drive motor may be a standard component and is connected to the mounting platform 21 by bolts, providing power to the entire first power unit 22. The first coupling connects the first drive motor and the first winch to transmit power from the first drive motor to the first winch. The first winch is equipped with a first traction cable 222, and the first drive motor drives the first winch to rotate along its own axis, thereby tightening or loosening the first traction cable 222 mounted on the first winch.

[0109] Optionally, the first power unit 22 further includes a second guide 223. The second guide 223 is connected to the mounting platform 21 and is positioned relative to the first power unit 22 and close to the first opening 211. The first traction cable 222 is connected to the hoisting seat 1 through the first guide 212. That is, one end of the first traction cable 222 is wound around the winch, and the other end passes through the second guide 223 and is connected to the hoisting seat 1.

[0110] Optionally, the second guide member 223 includes a guide mounting seat and a guide wheel rotatably connected to the guide mounting seat. The guide mounting seat is connected to the mounting platform 21 by bolts and mainly serves to support and fix the guide wheel. The guide wheel is mounted on the guide mounting seat and contacts the first traction cable 222 on the first winch. A groove 214 may be provided on the guide wheel, and the first traction cable 222 may be at least partially embedded in the groove 214 to guide and limit the first traction cable 222.

[0111] Please refer to Figures 9 and 10. Figure 9 shows a schematic diagram of the tooling body 2 in the embodiment of this application, and Figure 10 shows a schematic diagram of the tooling bracket 23 in the embodiment of this application.

[0112] In some alternative embodiments, the tooling body 2 further includes a tooling bracket 23, which is fixed to the foundation, and the mounting platform 21 is located on one side of the tooling bracket 23 along the first direction Z and can be at least partially supported on the tooling bracket 23.

[0113] By setting a tooling bracket 23 below the installation platform 21, the installation platform 21 can be supported on the tooling bracket 23 after it is lowered, thereby improving the reliability of the installation platform 21. Furthermore, compared to hoisting the entire tooling body 2, this embodiment of the application reduces the hoisting weight and lowers the performance requirements of the hoisting assembly by dividing the tooling body 2 into a tooling bracket 23 and an installation platform 21, and hoisting only the installation platform 21.

[0114] In some alternative embodiments, the tooling bracket 23 includes a bracket body 231 and a plurality of legs 232 disposed on the side of the bracket body 231 away from the tooling body 2, the size of the legs 232 being adjustable along the first direction Z.

[0115] The support body 231 is supported by multiple adjustable legs 232 along a first dimension. The entire tooling body 2 can be adjusted in the first direction Z by adjusting the dimension of the legs 232 along the first direction Z. At the same time, the influence of ground unevenness can be adapted by adjusting the dimension of each leg 232 along the first direction Z.

[0116] Optionally, the support body 231 includes a column arranged along the first direction Z, and a support leg 232 sleeved on the outer periphery of the column. The column and support leg 232 are provided with multiple through holes. The tooling support 23 also includes a connector, which passes through the through holes to fix the support leg 232 to different positions, thereby enabling the tooling body 231 to be adjusted in the first direction Z. Of course, the support leg 232 can also be configured as a telescopic rod or other structure, as long as it meets the adjustment requirements of the support leg 232 along the first direction Z.

[0117] Optionally, the support body 231 is provided with a second opening 233, which is concentrically arranged with the tower section 210. The support body 231 can be fitted onto the outer periphery of the tower section 210 through the second opening 233. In coordination with the installation platform 21, by providing the second opening 233 on the support body 231, the support body 231 can be fitted onto the outer periphery of the tower section 210, thereby providing stable support under the installation platform 21.

[0118] Please refer to Figures 9 to 12. Figure 11 shows a schematic diagram of the installation platform 21 in the embodiment of this application from one perspective, and Figure 12 shows an exploded view of the installation platform 21 in the embodiment of this application from another perspective.

[0119] In some alternative embodiments, the mounting platform 21 includes a plurality of platform units 213, which are spliced ​​together to form the mounting platform 21; and / or, the tooling bracket 23 includes a plurality of bracket units 2311, which are spliced ​​together to form the tooling bracket 23.

[0120] The installation platform 21 includes multiple platform units 213, each platform unit 213 including an arc segment. The arc segments of the multiple platform units 213 are spliced ​​together to form a first opening 211, so that the installation platform 21 can be installed around the outer periphery of the tower section 210 through the first opening 211. Similarly, the tooling bracket 23 includes multiple bracket units 2311, each bracket unit 2311 including an arc segment. The arc segments of the multiple bracket units 2311 are spliced ​​together to form a second opening 233, so that the tooling bracket 23 can be installed around the outer periphery of the tower section 210 through the second opening 233.

[0121] Optionally, the number of platform units 213 and / or support units 2311 can be adjusted according to actual needs. The number of platform units 213 and / or support units 2311 can be set to two or more. Taking two platform units 213 as an example, since multiple first power devices 22 and first guide members 212 are provided on the mounting platform 21, the multiple first power devices 22 and first guide members 212 can be symmetrically arranged on the platform unit 213.

[0122] Optionally, adjacent platform units 213 are connected by bolts, and / or adjacent support units 2311 are connected by bolts.

[0123] In some alternative embodiments, along the first direction Z, the orthographic projection of the splicing positions of the plurality of platform units 213 on the tooling bracket 23 is offset from the splicing positions of the plurality of bracket units 2311.

[0124] For example, when there are two support units 2311, the two support units 2311 are spliced ​​together along the second direction X. When there are two platform units 213, the two platform units 213 are spliced ​​together along the third direction Y, and the second direction X intersects with the third direction Y. By staggering the splicing positions of the multiple platform units 213 with the splicing positions of the multiple support units 2311, the stress can be distributed, reducing the risk of the installation platform 21 and / or tooling bracket 23 breaking at the splicing position and improving the reliability of the connection.

[0125] Optionally, along the first direction Z, on the side surfaces of the tooling bracket 23 and the mounting platform 21 facing each other, one is provided with a boss 234, and the other is provided with an elongated groove 219 adapted to the boss 234.

[0126] For example, as shown in Figures 10 and 12, a boss 234 can be provided on the tooling bracket 23 and a long groove 219 can be provided on the mounting platform 21. Through the cooperation of the boss 234 and the long groove 219, the boss 234 can support the mounting platform 21 and limit the mounting platform 21 to restrict the degree of freedom of movement of the mounting platform 21 along the second direction X and the third direction Y.

[0127] It is understandable that a long groove 219 can be directly opened on the lower surface of the mounting platform 21 to cooperate with the boss 234, or multiple protrusions can be set on the lower surface of the mounting platform 21. The multiple protrusions are spaced apart and form a long groove 219 between two adjacent protrusions. The protrusions abut against the boss 234 to achieve the limiting of the mounting platform 21 and the tooling bracket 23.

[0128] Optionally, both the tooling support 23 and the installation platform 21 are configured as truss structures to meet strength requirements. Additionally, steel plates or other reinforcing components can be laid at locations of high stress on the tooling support 23 and / or the installation support to more reliably meet the strength requirements of the tooling body 2. Simultaneously, by adopting a truss structure, the weight of the tooling body 2 can be reduced, making it easier to drive the installation platform 21 to move up and down in the first direction Z via the first power unit 22, thus reducing the requirements on the wall thickness and strength of the tower section 210.

[0129] Please refer to Figures 9 to 13. Figure 13 shows a schematic diagram of the structure in which the lifting device body 3 is connected to the installation platform 21 via the adapter mechanism 24 in an embodiment of this application.

[0130] In some optional embodiments, the tooling body 2 further includes a transfer mechanism 24, which is disposed on the installation platform 21. The lifting body 3 is movably connected to the transfer mechanism 24 and can be moved relative to the transfer mechanism 24 along the second direction X, so that one tower section 210 is installed on another tower section 210 or the wind turbine component is installed on the tower 20. The second direction X intersects with the first direction Z.

[0131] By setting a transfer mechanism 24 on the installation platform 21, the lifting body 3 can be guided to move along the second direction X through the transfer mechanism 24, so as to move the tower section 210 and / or the wind turbine component along the second direction X to the first opening 211, thereby realizing the installation of the tower section 210 and / or the wind turbine component.

[0132] Please refer to Figures 9 to 14. Figure 14 shows a schematic diagram of the structure of the platform unit 213 in the embodiment of this application.

[0133] As the lifting device 3 moves relative to the transfer mechanism 24 along the second direction X, the center of gravity of the installation equipment 200 also changes. In some optional embodiments, the tooling body 2 further includes a counterweight assembly 25 disposed on the side wall of the installation platform 21. The counterweight assembly 25 includes a drive assembly 251, a counterweight 252, a controller, and a sensing device. The sensing device is used to monitor the center of gravity position of the tooling body 2 in real time. The controller is configured to control the drive assembly 251 to drive the counterweight 252 to move relative to the tooling body 2 according to the center of gravity position, so as to transfer the center of gravity position of the tooling body 2 to the center of the tooling body 2.

[0134] By setting a counterweight assembly 25 on the installation platform 21, sensors can automatically sense the center of gravity or tilt angle of the entire installation equipment 200 and the hoisted tower section 210 and / or wind turbine components. The controller controls the movement of the counterweight 252 through the drive assembly 251. This ensures that when the hoisted tower section 210 and / or wind turbine components move to different positions along the second direction X, the center of gravity of the entire installation equipment 200 and the hoisted components are all located at the center of gravity of the wind turbine generator set 100 foundation, improving the stability of the installation process.

[0135] Optionally, each platform unit 213 may be equipped with a counterweight component 25, so that when the lifting body 3 moves relative to the two sides of the transfer mechanism 24 along the second direction X, the counterweight components 25 on both sides of the platform unit 213 can be adjusted simultaneously, so that the drive components 251 on both sides of the platform unit 213 can act synchronously, and the counterweight 252 can always be kept in a symmetrical state for easy position adjustment.

[0136] Please refer to Figures 9 to 16. Figure 15 shows a structural schematic diagram of the counterweight frame 2521 in the embodiment of this application, and Figure 16 shows a structural schematic diagram of the counterweight 252 in the embodiment of this application.

[0137] In some alternative embodiments, the counterweight 252 includes a counterweight frame 2521 and a counterweight part 2522, the counterweight frame 2521 being connected to the mounting platform 21, and the counterweight part 2522 being detachably connected to the counterweight frame 2521.

[0138] The counterweight frame 2521 serves as the carrier for the entire counterweight 252. By detachably connecting the counterweight part 2522 to the counterweight frame 2521, the quantity and / or specifications of the counterweight part 2522 can be increased or decreased according to actual needs, so as to adjust the total weight of the counterweight 252 according to specific counterweight requirements.

[0139] Optionally, the counterweight frame 2521 encloses a receiving space, within which a connecting post 2523 is provided. The counterweight part 2522 is provided with a through hole that mates with the connecting post 2523, and the counterweight part 2522 can be installed on the connecting post 2523. Multiple connecting posts 2523 can be provided, and the counterweight part 2522 is provided with multiple through holes corresponding to the connecting posts 2523. By passing the counterweight part 2522 through the connecting post 2523, rotation of the counterweight part 2522 relative to the counterweight frame 2521 is prevented, thus improving the reliability of the counterweight part 252.

[0140] Optionally, the connecting column 2523 is detachably connected to the counterweight frame 2521, and / or the length of the connecting column 2523 is adjustable, so that the length of the connecting column 2523 can be adjusted according to the number of counterweights to be installed.

[0141] In some alternative embodiments, the mounting platform 21 has a sidewall extending along a second direction X, and a counterweight 252 is connected to the sidewall and movable relative to the sidewall along the second direction X. By placing the counterweight 252 on the sidewall of the mounting platform 21 along a third direction Y, interference from the movement of the counterweight 252 to other components on the mounting platform 21 or the lifting device body 3 can be avoided, while increasing the adjustment range of the counterweight 252 along the second direction X and improving the reliability of the adjustment.

[0142] Optionally, one of the mounting platform 21 and the counterweight 252 is provided with a groove 2524 extending along the second direction X, and the other is provided with a slide rail 215 that cooperates with the groove 2524. For example, the slide rail 215 can be provided on the side wall of the mounting platform 21, and the groove 2524 can be provided on the counterweight 252 to cooperate with the slide rail 215. The groove 2524 of the counterweight 252 can be set as a T-slot. The counterweight 252 can also cooperate with the slide rail 215 and move along the second direction X. At the same time, the slide rail 215 can limit the counterweight 252 to restrict the degree of freedom of the counterweight 252 to detach from the side wall of the mounting platform 21 along the third direction Y, thereby improving the reliability of sliding.

[0143] Optionally, the number of slide rails 215 can be one or more. Two or more slide rails 215 can be arranged at intervals along the first direction Z on the side wall of the mounting platform 21. Correspondingly, the number of slide grooves 2524 can also be two or more and slidably connected to the slide rails 215.

[0144] In some optional embodiments, the side wall of the mounting platform 21 is provided with a second support plate 216 for supporting the counterweight 252. The counterweight 252 also includes a roller 2525, which is rotatably connected to the side surface of the counterweight frame 2521 facing the second support plate 216. The counterweight 252 cooperates with the second support plate 216 through the roller 2525. By placing the roller 2525 of the counterweight 252 on the second support plate 216, the frictional resistance is reduced while supporting the counterweight 252, making the movement of the counterweight 252 smoother, thereby making the counterweight 252 more responsive and the counterweight effect more accurate.

[0145] Optionally, the number of rollers 2525 can be one or more, for example, three rollers 2525 can be provided, and the three rollers 2525 are spaced apart along the second direction X on the counterweight frame 2521. In addition, as shown in Figure 12, the second support plate 216 of the mounting platform 21 can also be provided with reinforcing ribs 217 on the side surface opposite to the counterweight 252, so as to support the second support plate 216 of the counterweight and prevent its plane from deforming.

[0146] Please refer to Figures 9 to 17. Figure 17 shows a schematic diagram of the structure of the drive component 251 in the embodiment of this application.

[0147] In some alternative embodiments, the drive assembly 251 includes two third drive members 2511 disposed opposite each other along a second direction X, and a third traction cable 2512 connected between the two third drive members 2511. The third traction cable 2512 extends at least partially onto the side wall of the platform unit 213 and is fixed to the counterweight 252. The output end of one of the opposing third drive members 2511 winds up the third traction cable 2512, while the output end of the other releases the third traction cable 2512.

[0148] Each platform unit 213 may be equipped with two drive components 251, which are mounted on the side walls at both ends of the platform unit 213 along the second direction X. Both drive components 251 of the same platform unit 213 are connected to the counterweight 252 via a third traction cable 2512, providing power for the movement of the counterweight 252 along the second direction X. Through control logic, when one drive component 251 tightens the third traction cable 2512, the other drive component 251 loosens the third traction cable 2512, thereby moving the counterweight 252 toward the end where the third traction cable 2512 is tightened, so that the entire installation equipment 200 does not become eccentric.

[0149] Optionally, the third drive unit 2511 includes a third drive motor, a transmission belt, and a third winch. The third drive motor can be a standard component and is connected to the mounting platform 21 via bolts, providing power for the movement of the counterweight 252. The transmission belt can also be a standard component, connecting the third drive motor and the third winch, thus employing belt drive to transmit power from the third drive motor to the third winch. The third winch is equipped with a third traction cable 2512. The third drive motor drives the third winch to rotate along its own axis, tightening or loosening the third traction cable 2512 mounted on the third winch.

[0150] Optionally, the counterweight assembly 25 further includes a third guide member 2513. The third guide member 2513 is connected to the mounting platform 21 and disposed between the third drive member 2511 and the counterweight member 252. The third guide member 2513 is supported by the third traction cable 2512 and spaced apart from the side wall of the platform unit 213. The third guide member 2513 can be configured as a guide wheel. The third guide member 2513 contacts the third traction cable 2512 and serves to guide and limit the third traction cable 2512.

[0151] In some optional embodiments, as shown in FIG9, the tooling body 2 further includes a control cabinet 26 and a power supply cabinet 27. The control cabinet 26 and power supply cabinet 27 are each mounted on a platform unit 213, forming a symmetrical distribution to avoid eccentricity in the entire equipment. The control cabinet 26 controls the installation equipment 200, and the power supply cabinet 27 provides power to the entire installation equipment 200. Furthermore, the tooling body 2, as the carrier of the entire installation equipment 200, may include other large components besides the lifting device body 3, counterweight assembly 25, control cabinet 26, and power supply cabinet 27. These large components can be evenly distributed on multiple platform units 213, and their specific locations can be adjusted according to the structure of the installation platform 21; this application does not specifically limit their placement.

[0152] Please refer to Figures 9 to 19. Figure 18 shows a schematic diagram of the structure of the guide rail 241 in the embodiment of this application, and Figure 19 shows a schematic diagram of the structure of the lifting support 243 in the embodiment of this application.

[0153] In some alternative embodiments, the adapter 24 includes a guide rail 241 extending along the second direction X, a fourth drive member 242, and a lifting device support 243. The lifting device support 243 is connected to the guide rail 241, and the fourth drive member 242 is used to drive the lifting device support 243 to move relative to the guide rail 241 along the second direction X. The lifting device body 3 is connected to the lifting device support 243.

[0154] By connecting the spreader body 3 to the spreader support 243, the spreader support 243 can be driven to move relative to the guide rail 241 in the second direction X by the fourth drive member 242, thereby driving the spreader body 3 on it to move relative to the transfer mechanism 24 in the second direction X, so as to improve the reliability of the spreader body 3 moving in the second direction X.

[0155] Optionally, as shown in Figure 14, the mounting platform 21 may be provided with a protrusion 218. As shown in Figure 18, the guide rail 241 includes a first slot 2411 and a second slot 2412 arranged opposite each other along the first direction Z. The first slot 2411 may be configured as a C-shaped slot for connecting with the protrusion 218 on the mounting platform 21 and for fixing with bolts. The second slot 2412 may be configured as a T-shaped slot for connecting with the lifting device support 243 and for limiting and guiding functions.

[0156] Optionally, as shown in Figure 19, the lifting device support 243 includes a main base 2431 and a rolling hub 2432 disposed on the side of the main base 2431 facing the guide rail 241. The main base 2431 serves as the carrier for the fourth drive component 242 and also houses the lifting device body 3. The main base 2431 is mounted on the guide rail 241, with one main base 2431 mounted on each guide rail 241. The T-shaped protrusion on the main base 2431 engages with the second slot 2412 of the guide rail 241, serving as a guide rail and limiting point. The main base 2431 also engages with the guide rail 241 via the rolling hub 2432 to provide support and reduce damping.

[0157] The fourth driving component 242 is connected to the main body base 2431 by bolts. The fourth driving component 242 may include a fourth driving motor and a gear, which meshes with a rack on the guide rail 241. The fourth driving motor drives the gear to rotate, thereby enabling the lifting support 243 to move along the guide rail 241. It is understood that the power forms used in different parts of the installation equipment 200 in this application embodiment are different. In some other embodiments, the gear and rack transmission can be replaced with other structural forms, such as belt transmission, chain transmission, etc., or other linear drive mechanisms such as ball screws and telescopic rods can also be used. This method can be interchanged in various places as long as the performance requirements are met, and no specific transmission form is specified.

[0158] Optionally, the spreader support 243 may be provided with a plurality of fourth drive members 242, for example, three fourth drive members 242 may be provided. The three fourth drive members 242 are spaced apart along the second direction X and all mesh with the rack, so that the spreader support 243 can be driven to move relative to the guide rail 241 along the second direction X by the plurality of fourth drive members 242, thereby improving the reliability of movement.

[0159] In some embodiments, the lifting device support 2433 may be provided with multiple sets of rolling hubs 2432. The rolling hubs 2432 in the same set are spaced apart along the second direction X. The multiple sets of rolling hubs 2432 are respectively provided on both sides of the second slot 2412. The size of the rolling hub 2432 on the side closer to the fourth driving member 242 can be smaller, and the size of the rolling hub 2432 on the side farther away from the fourth driving member 242 can be larger. The specific size can be adjusted according to the structure of the lifting device support 243. Their functions are all to support and reduce damping.

[0160] In some alternative embodiments, the spreader body 3 is detachably connected to the spreader support 243.

[0161] Since the lifting device body 3 needs to lift the tower section 210 and the wind turbine components, by making the lifting device body 3 detachably connected to the lifting device support 243, the lifting device body 3 can be replaced according to the components to be lifted. For example, when lifting the tower section 210, the lifting device body 3 can be replaced with the tower lifting device 31, and when lifting the wind turbine components, the lifting device body 3 can be replaced with the lifting device body 3 used for lifting the wind turbine components, so as to lift the components to be lifted in a targeted manner, improve the reliability of the lifting, and thus realize the installation of the entire wind turbine generator set 100.

[0162] It is understood that the lifting device body 3 can be any existing lifting device body capable of lifting the tower section 210 and / or wind turbine components. Furthermore, the lifting device body 3 can also be a general-purpose lifting device body; in some other embodiments, the lifting device body 3 can also be a crane, meaning the specific structure of the lifting device body 3 can be adjusted according to actual needs.

[0163] Please refer to Figures 13, 20 and 21. Figure 20 shows a schematic diagram of the structure of the tower lifting device 31 in the embodiment of this application, and Figure 21 shows a schematic diagram of the structure of the clamping assembly 311 in the embodiment of this application.

[0164] As an optional implementation, as shown in FIG20, the lifting device body 3 includes a tower lifting device 31. The tower lifting device 31 includes a pair of clamping components 311 arranged along a third direction Y. The clamping components 311 are connected to the adapter mechanism 24 and can move closer or further apart along the third direction Y to clamp or release the tower section 210. The third direction Y intersects with the first direction Z and the second direction X. That is, the tower lifting device 31 can be used to clamp the tower section 210. By setting the tower lifting device 31 to a pair of clamping components 311 arranged along the third direction Y, the movement of the clamping components 311 along the third direction Y can be controlled to achieve the clamping of the tower lifting device 31.

[0165] Optionally, since the clamping components 311 are arranged opposite each other along the third direction Y, the adapter mechanisms 24 are arranged in pairs along the third direction Y at both ends of the mounting platform 21 in cooperation with the clamping components 311, and the clamping components 311 are respectively connected to the adapter mechanisms 24 on both sides.

[0166] When the installation platform 21 includes platform units 213 arranged along the third direction Y, each platform unit 213 may be provided with a transition mechanism 24 extending along the second direction X. The clamping assembly 311 is detachably connected to the lifting support seat 243 of the transition mechanism 24 on both sides, so that it can be moved synchronously along the second direction X under the drive of the transition mechanism 24. The movement is more stable and reliable, and it is also easier to clamp the tower section 210 to move to the first opening 211 position to realize the subsequent installation of the tower section 210.

[0167] Optionally, the clamping assemblies 311 on both sides are symmetrically structured relative to the mounting platform 21. Each clamping assembly 311 includes a first lifting base 3111, a fifth driving member 3112, and a clamping member 3113. The first lifting base 3111 is connected to the adapter mechanism 24. The clamping member 3113 is adapted to the outer wall surface of the tower section 210. The fifth driving member 3112 is used to drive the clamping member 3113 to reciprocate relative to the first lifting base 3111 along the third direction Y to clamp or release the tower section 210.

[0168] The first lifting device base 3111 is detachably connected to the lifting device support 243 via bolts. The first lifting device base 3111 is connected to the clamping member 3113 via the fifth driving member 3112. The clamping member 3113 can be configured as a semi-circular structure so that after the clamping members 3113 on both sides move closer to each other along the third direction Y, they can form a concentric structure with the tower section 210 to achieve clamping of the tower section 210.

[0169] It is understandable that the clamping assembly 311 can have different specifications. By making the first lifting base 3111 detachably connected to the lifting body 3, the clamping assembly 311 of different specifications can also be replaced according to the tower section 210 with different outer diameters, so as to be suitable for reliable clamping of tower section 210 of various specifications and improve the reliability of tower section 210 assembly.

[0170] To further improve the reliability of the clamping member 3113 moving relative to the first lifting base 3111 along the third direction Y, in some optional embodiments, the first lifting base 3111 may be provided with a limiting groove, and the clamping member 3113 may be provided with a protrusion adapted to the limiting groove. The protrusion is slidably connected to the limiting groove along the third direction Y and the limiting groove can restrict the degree of freedom of the protrusion along the first direction Z and the second direction X, so that the clamping member 3113 can only move relative to the first lifting base 3111 along the third direction Y, thereby improving the reliability of the movement of the clamping member 3113. Optionally, the limiting groove may be set as a T-shaped groove, and the protrusion may be set as a T-shaped protrusion that cooperates with the T-shaped groove to play a guiding and limiting role.

[0171] The fifth driving component 3112 can be configured as a hydraulic cylinder. Of course, in some other implementations, the fifth driving component 3112 can also be configured as a telescopic rod, a ball screw or other linear drive mechanism, which can drive the clamping component 3113 to move along the third direction Y.

[0172] Optionally, the number of hydraulic cylinders can be set to two or more, with the two or more hydraulic cylinders spaced apart along the second direction X on the first lifting device base 3111 and abutting against different areas of the clamping member 3113. For example, four hydraulic cylinders can be set so that the clamping member 3113 can be driven to move along the third direction Y by the synchronous extension and retraction of the four hydraulic cylinders, so that the abutting force of the clamping member 3113 in each area along the third direction Y is more uniform, improving the clamping effect on the tower section 210. The hydraulic cylinders are standard parts, and the appropriate length is selected according to the different fixed positions with the clamping member 3113 to provide power for the movement of the clamping member 3113.

[0173] Please refer to Figures 13 and 22. Figure 22 shows a schematic diagram of the structure of the nacelle spreader 32 in the embodiment of this application.

[0174] As an optional implementation, the lifting device body 3 includes a nacelle lifting device 32. The nacelle lifting device 32 includes support beams 321 arranged opposite each other along a third direction Y and lifting beams 322 connected between the support beams 321. The support beams 321 are connected to the transfer mechanism 24. Lifting points 323 are provided on the lifting beams 322 for lifting the nacelle 30. The third direction Y intersects with the first direction Z and the second direction X.

[0175] Optionally, the support beam 321 is positioned opposite to the spreader support base 243 along the third direction Y. The support beam 321 has a preset height along the first direction Z. One end of the support beam 321 along the first direction Z is fixedly connected to the spreader support base 243 by bolts, and the other end is supported by the lifting beam 322. The height of the support beam 321 along the first direction Z can be adjusted according to the nacelle 30 to be lifted, ensuring that the lifting beam 322 can lift the nacelle 30 through the lifting point 323.

[0176] Optionally, the support beam 321 and the lifting beam 322 can be detachably connected, that is, the lifting beam 322 and the support beam 321 are designed separately, so that the support beam 321 and the lifting beam 322 can be transported separately and assembled on site, reducing the difficulty of manufacturing and transportation.

[0177] In some optional embodiments, the support beam 321, which supports the end of the lifting beam 322, may be provided with a limiting part. For example, the limiting part may include a limiting platform spaced apart along the second direction X. The end of the lifting beam 322 may be engaged between two adjacent limiting platforms along the second direction X to limit the lifting beam 322 along the second direction X. Furthermore, the number of limiting parts may be one or more. Multiple limiting parts may be spaced apart along the second direction X, and the lifting beam 322 may have multiple corresponding ends, each end being positioned between two limiting platforms of the limiting part, so that the lifting beam 322 is limited during assembly through multiple limiting parts.

[0178] Optionally, the number of lifting points 323 can also be set to multiple. The position and structure of the lifting points 323 can be adjusted according to the position of the lifting lugs on the cabin 30. This application does not make specific limitations in this regard.

[0179] Optionally, both the support beam 321 and the lifting beam 322 are configured as truss structures to reduce the weight of the nacelle lifting device 32 while ensuring sufficient structural strength. This makes it easier to drive the installation platform 21 to move up and down in the first direction Z via the first power unit 22, thereby reducing the requirements on the wall thickness and strength of the tower section 210.

[0180] Please refer to Figures 13, 23 and 24. Figure 23 shows a schematic diagram of the structure of the hub hanger 33 in the embodiment of this application, and Figure 24 shows a schematic diagram of the structure of the limiting plate in the embodiment of this application.

[0181] As an optional implementation, the lifting device body 3 includes a hub lifting device 33, which includes a second lifting device base 331 and a carrier member 332 supported on the second lifting device base 331. The second lifting device base 331 is connected to the adapter mechanism 24, and the carrier member 332 is rotatably connected to the second lifting device base 331, with the axis of rotation of the carrier member 332 extending along a third direction Y, so that the tilt angle of the carrier member 332 relative to the second lifting device base 331 is adjustable, and the third direction Y intersects with the first direction Z and the second direction X.

[0182] When assembling the hub 40 onto the nacelle 30, the installation angle of the hub 40 relative to the nacelle 30 needs to be adjusted to accommodate different pitch angles of the wind turbine generator set 100. Therefore, to facilitate the connection between the hub 40 and the nacelle 30, the support member 332 of the hub spreader 33 can be rotatably connected to the second spreader base 331, and the hub 40 can be installed on the support member 332. Thus, by adjusting the relative angle between the support member 332 and the second spreader base 331, the hub 40 can be installed on the nacelle 30 at a predetermined angle.

[0183] Optionally, the second lifting base 331 is connected to the lifting support 243 of the adapter mechanism 24 on both sides. The bearing member 332 is provided with a rotating shaft at both ends along the third direction Y. The rotating shaft is rotatably connected to the second lifting base 331 to improve the stability of the bearing member 332 relative to the second lifting base 331.

[0184] Optionally, the second lifting device base 331 includes a seat body and a first limiting plate 335 detachably connected to the seat body. The seat body and the first limiting plate 335 enclose a rotating groove, and a rotating shaft is disposed within the rotating groove and rotatably engages with the rotating groove. By detachably connecting the seat body and the first limiting plate 335, assembly is facilitated. Furthermore, only the load-bearing component 332 needs to be replaced according to the wheel hub 40 specification, without replacing the entire lifting device body 3, thus saving costs.

[0185] In some alternative embodiments, the hub lifting device 33 further includes a first support plate 333 and a sixth drive member 334. The first support plate 333 is connected to the adapter mechanism 24, and the sixth drive member 334 is connected between the first support plate 333 and the carrier member 332 along a first direction Z. The sixth drive member 334 is configured to drive the carrier member 332 to rotate relative to the second lifting device base 331 to adjust the tilt angle of the carrier member 332 relative to the second lifting device base 331.

[0186] Among them, one end of the bearing member 332 is connected to the first support plate 333 through the sixth drive member 334, and the other end is provided with a rotating shaft and rotates in cooperation with the second lifting device base 331. The bearing member 332 is driven to rotate relative to the second lifting device base 331 through the sixth drive member 334, so as to more reliably realize the adjustment of the tilt angle of the bearing member 332 relative to the second lifting device base 331.

[0187] Optionally, the first support plate 333 extends along the third direction Y and its two ends are respectively connected to the spreader support seats 243 of the two-sided transfer mechanism 24, so as to fix the sixth drive member 334 through the first support plate 333. The sixth drive member 334 can be configured as a hydraulic cylinder, which is used to connect the first support plate 333 and the carrier 332. Under the action of the hydraulic cylinder, the carrier 332 can rotate relative to the second spreader base 331 to adapt to different elevation angles of the wind turbine generator set 100.

[0188] Please refer to Figures 13, 25 to 27. Figure 25 shows a schematic diagram of the blade lifting device 34 in one view in an embodiment of this application. Figure 26 shows a schematic diagram of the blade lifting device 34 in another view in an embodiment of this application. Figure 27 shows a schematic diagram of the second limiting plate 344 in an embodiment of this application.

[0189] As an optional implementation, the lifting device body 3 includes a blade lifting device 34, which includes a third lifting device base 341 and a clamping structure 342 rotatably connected to the third lifting device base 341. The third lifting device base 341 is connected to the adapter mechanism 24. The rotation axis of the clamping structure 342 is parallel to the second direction X. The clamping structure 342 is used to clamp the blade 50 and can drive the blade 50 to rotate relative to the tooling body 2.

[0190] Since the blade 50 has a certain height, in order to facilitate the lifting of the blade 50 by the lifting device body 3, the clamping structure 342 can be rotatably connected to the third lifting device base 341. This allows the blade 50 to be positioned horizontally during lifting. Then, when the blade lifting device 34 is lifted to a preset height along the first direction Z by the mounting platform 21, the blade 50 is rotated to a vertical position for assembly onto the hub 40. This design saves space occupied by the blade lifting device 34 and improves its reliability.

[0191] Optionally, the third lifting base 341 is connected to the lifting support 243 of the adapter mechanism 24 on both sides. The clamping structure 342 is provided with a rotating shaft in the middle area along the third direction Y. The rotating shaft protrudes from the clamping structure 342 along the second direction X and is rotatably connected to the third lifting base 341 to improve the stability of the clamping structure 342 relative to the third lifting base 341.

[0192] Optionally, as shown in Figure 25, the blade lifting device 34 further includes a seventh driving member 343, which is disposed on the third lifting device base 341. The seventh driving member 343 is configured to drive the clamping structure 342 to rotate relative to the third lifting device base 341, thereby adjusting the rotation angle of the clamping structure 342 relative to the third lifting device base 341. For example, the seventh driving member 343 can be configured as a gear structure, which is used to cooperate with an external drive motor. The external drive motor drives the gear to rotate, thereby driving the entire clamping structure 342 to rotate relative to the third lifting device base 341.

[0193] Optionally, as shown in Figure 27, the third lifting device base 341 includes a base body and a second limiting plate 344 detachably connected to the base body. The base body is the carrier of the entire blade lifting device 34 and is connected to the lifting device support seat 243 of the adapter mechanism 24 by bolts. The second limiting plate 344 is connected to the base body and forms a rotating groove with the base body. The rotating shaft of the clamping structure 342 is set in the rotating groove and rotates with the rotating groove.

[0194] Please refer to Figures 13, 25 to 29. Figure 28 shows a schematic diagram of the structure of the first clamping arm 3422 in an embodiment of this application, and Figure 29 shows a schematic diagram of the structure of the second clamping arm 3423 in an embodiment of this application.

[0195] To reliably clamp the blade 50 using the clamping structure 342, in some optional embodiments, as shown in FIG25, the clamping structure 342 includes a clamping body 3421 and a first clamping arm 3422 and a second clamping arm 3423 disposed on one side of the clamping body 3421. A clamping space for clamping the blade 50 is formed between the first clamping arm 3422 and the second clamping arm 3423. At least one of the first clamping arm 3422 and the second clamping arm 3423 can be rotated toward the other to clamp or release the blade 50.

[0196] Optionally, the first clamping arm 3422 and the second clamping arm 3423 form a clamping group. The clamping structure 342 may include one clamping group or multiple clamping groups. The multiple clamping groups are spaced apart along the third direction Y so that the blade 50 can be clamped simultaneously by the multiple clamping groups, thereby improving the clamping effect of the clamping structure 342 on the blade 50.

[0197] As an optional implementation, as shown in FIG28, the first clamping arm 3422 includes a first clamping arm mounting base 34221 and a first clamping portion 34222 disposed on the first clamping arm mounting base 34221. The first clamping arm mounting base 34221 is connected to the clamping body 3421, and the first clamping portion 34222 is rotatably connected to the first clamping arm mounting base 34221. The rotation axis of the first clamping portion 34222 extends along the second direction X. By rotatably connecting the first clamping portion 34222 to the first clamping arm mounting base 34221, the first clamping portion 34222 can be rotated to better fit the surface of the blade 50.

[0198] Correspondingly, as shown in Figure 29, the second clamping arm 3423 includes a second clamping arm mounting base 34231 and a second clamping part 34232 disposed on the second clamping arm mounting base 34231. The second clamping arm mounting base 34231 is connected to the clamping body 3421, and the second clamping part 34232 is rotatably connected to the second clamping arm mounting base 34231. The rotation axis of the second clamping part 34232 extends along the second direction X. By rotatably connecting the second clamping part 34232 to the second clamping arm mounting base 34231, the second clamping part 34232 can rotate to better fit the surface of the blade 50. Thus, the blade 50 can be better clamped through the cooperation of the first clamping part 34222 and the second clamping part 34232.

[0199] Taking the second clamping arm 3423 as an example, which can rotate toward the first clamping arm 3422, the clamping structure 342 further includes an eighth driving member 345. The second clamping arm mounting base 34231 is rotatably connected to the clamping body 3421, and the rotation axis of the second clamping arm mounting base 34231 extends along the third direction Y. One end of the eighth driving member 345 is connected to the clamping body 3421, and the other end is connected to the second clamping arm mounting base 34231. At least one of the first clamping arm 3422 and the second clamping arm 3423 can rotate toward the other to clamp or release the blade 50. Optionally, the eighth driving member 345 can be configured as a hydraulic cylinder.

[0200] It should be noted that the lifting device body 3 listed in the embodiments of this application for clamping the tower section 210 and the wind turbine components is only one form that meets the requirements. Other lifting device bodies 3 that can meet the requirements of the tower section 210 and the wind turbine components can also be applied to the installation equipment 200 of the embodiments of this application. In addition, when the wind turbine components also include other components, the number of lifting device bodies 3 can be increased accordingly, that is, as long as the assembly requirements of the wind turbine generator set 100 are met.

[0201] It is understood that by using the installation equipment 200 in this embodiment, the installation platform 21 can be raised to the height of the tower section 210 using the lifting base 1 as a lifting point, so that the subsequent lifting of the tower section 210 and / or wind turbine components can be achieved through the lifting body 3 on the installation platform 21. Using the above-mentioned installation equipment 200, the performance requirements of the lifting body 3 can be reduced when installing wind turbine generators, overcoming the bottleneck of wind turbine generator 100 developing towards higher towers 20 and larger capacities. Furthermore, since the lifting body 3 is all set on the installation platform 21, the platform area required for wind turbine generator 100 installation can be reduced, increasing the applicable scenarios for wind turbine generator 100 installation, saving ecological area, and protecting the natural environment. In addition, the installation efficiency is higher, the allowable operating wind speed can be increased, and the lifting window period can be extended, showing broad application prospects.

[0202] Please refer to Figures 30 to 52. Based on the installation device 200 in the above embodiments, this application also provides an installation method for a wind turbine generator set 100, including:

[0203] In S10, the preparation step includes: providing multiple tower sections 210, wind turbine components, and installation equipment 200 as described in the above embodiment; installing the initial tower section 210; and connecting the first traction cable 222 of the installation equipment 200 to the hanger 1 of the initial tower section 210.

[0204] In step S20, the installation of tower 20 includes: using the lifting device 3 to clamp another tower section 210, driving the first power device 22 to lift the tooling body 2 along the first direction Z to a preset height, and using the lifting device 3 to hoist the tower section 210 onto the upper part of the initial tower section 210, driving the first power device 22 to lower the tooling body 2, and then connecting the first traction cable 222 to the lifting seat 1 of the upper tower section 210, repeating the above steps until the installation of tower 20 is completed.

[0205] In step S30, the wind turbine component installation step includes: connecting the first traction cable 222 to the lifting seat 1 of the upper tower section 210, driving the first power unit 22 to lift the tooling body 2 along the first direction Z to a preset height, and assembling the wind turbine component onto the tower 20 by the lifting body 3, releasing the first traction cable 222 through the first drive member 221, driving the first power unit 22 to lower the tooling body 2, and repeating the above steps until the installation of the wind turbine generator set 100 is completed.

[0206] Please refer to Figures 31 and 32. For step S10, taking the tower 20 of the wind turbine generator set 100 as an example, which includes a first tower section 210a and a second tower section 210b, the initial tower section 210 is the first tower section 210a. The installation of the first tower section 210a can be done in a conventional way. For example, the electrical cabinet and the first tower section 210a can be installed first by using a crane 300, so that the installation of all other components of the wind turbine generator set 100 can be completed by using the first tower section 210a as a lifting point.

[0207] The first traction cable 222 of the installation equipment 200 is connected to the lifting seat 1 of the initial tower section 210. Specifically, this may include an assembly tooling bracket 23 and an installation platform 21. The outriggers 232 of the tooling bracket 23 are adjusted so that the surface of the installation platform 21 is horizontal. The first traction cable 222 of the installation equipment 200 is then connected to the lifting seat 1 of the first tower section 210a, and the counterweight assembly 25 is also moved to a suitable position to ensure that the center of gravity of the entire installation equipment 200 is at the center of gravity of the wind turbine generator 100. In addition, the tower lifting device 31 can be opened to facilitate the subsequent insertion of the tower section 210, thereby realizing the wind turbine generator 100.

[0208] Please refer to Figures 33 to 37. Step S20 can be performed according to the following steps:

[0209] Referring to Figure 33, the second tower section 210b is lifted by an external crane 300, moved above the tower lifting device 31, and slowly lowered to a suitable position. The fifth drive members 3112 of the clamping assemblies 311 on both sides of the tower lifting device 31 are controlled to move synchronously, so that the clamping members 3113 of the clamping assemblies 311 gradually clamp the second tower section 210b until the pressure reaches the set value.

[0210] Crane 300 gradually reduces its lifting force. Through the control system settings, the counterweight component 25 on the installation equipment 200 moves synchronously, ensuring that the overall center of gravity of the installation equipment 200 and the second tower section 210b remains at the center of the wind turbine generator 100 foundation throughout the process, until crane 300 no longer provides lifting force to the second tower section 210b. The lifting device connecting the second tower section 210b and crane 300 is then removed, completing the placement of the second tower section 210b on the tower lifting device 31 of the installation equipment 200.

[0211] Please refer to Figure 34. The first traction cable 222 is tightened synchronously by the first power device 22, which drives the entire installation platform 21 and the second tower section 210b to rise along the first direction Z and lift them to a suitable position. For example, after the space is sufficient for the tower lifting device 31 to move the second tower section 210b along the second direction X, the movement stops when the lower flange of the second tower section 210b is about 100mm away from the upper flange of the first tower section 210a.

[0212] Please refer to Figure 35. The clamping components 311 on both sides of the drive move synchronously along the second direction X, causing the second tower section 210b to move towards the first tower section 210a along the second direction X until the second tower section 210b and the first tower section 210a reach a concentric position. During this process, the counterweight component 25 will also move synchronously towards the center of the wind turbine generator 100 foundation along the second direction X, so that the center of gravity of the assembly of the installation equipment 200 and the second tower section 210b is at the center of the wind turbine generator 100 foundation.

[0213] The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation equipment 200 and the second tower section 210b to descend in the first direction Z, so that the lower flange of the second tower section 210b coincides with the upper flange of the first tower section 210a. The first tower section 210a and the second tower section 210b are connected by installation bolts until all connecting bolts are tightened.

[0214] Referring to Figure 36, the fifth drive members 3112 of the clamping assemblies 311 on both sides of the control tower spreader 31 move synchronously, causing the clamping members 3113 of the clamping assemblies 311 to gradually loosen the second tower section 210b along the third direction Y, until the distance between the clamping assemblies 311 on both sides is greater than the outer diameter of the second tower section 210b. The clamping assemblies 311 on both sides are then driven to move synchronously along the second direction X, moving towards the initial position. The counterweight assembly 25 will also move synchronously, ensuring that the center of gravity of the installed equipment 200 is at the center of the wind turbine generator 100 foundation.

[0215] Please refer to Figure 37. The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation platform 21 to descend along the first direction Z until the installation platform 21 lands on the tooling bracket 23, thereby completing the installation of the second tower section 210b and realizing the installation of the wind turbine generator 100 tower 20.

[0216] After the installation of the wind turbine generator set 100 tower 20 is completed, the connecting bolts between the hanging bracket 1 and the first tower section 210a can be removed, and the hanging bracket 1 can be lowered to the installation platform 21 under the action of the hanging bracket hoist 4.

[0217] It is understood that the above examples all take the tower 20 including the first tower section 210a and the second tower section 210b as examples. In some other embodiments, the tower 20 may include more tower sections 210. The installation process of other tower sections 210 is the same. The steps of Figures 33 to 37 above can be repeated until the installation of the tower 20 is completed. The installation of other tower sections 210 will not be described again here.

[0218] For wind turbine components, they may include at least one of nacelle 30, hub 40 and blade 50. Therefore, in step S30, the nacelle 30, hub 40 and blade 50 can be assembled respectively to realize the installation of wind turbine generator set 100.

[0219] Please refer to Figures 38 to 42. The assembly of the engine compartment 30 in step S30 can be carried out according to the following steps:

[0220] Referring to Figure 38, remove the hoist 4 from the first tower section 210a and install the hoist 4 on the inner wall of the second tower section 210b. Tighten the second traction cable 43 by the hoist 4, causing the hoist 1 to move upward in the first direction Z until the hoist 1 moves to the hoist installation position 220 on the outer wall of the second tower section 210b. Insert a connector into the inner wall of the second tower section 210b to fix the hoist 1 to the second tower section 210b. Remove the tower lifting device 31 from the adapter mechanism 24 and install the nacelle lifting device 32 on the adapter mechanism 24.

[0221] The installation of the nacelle lifting device 32 on the transfer mechanism 24 specifically includes installing the support beam 321 onto the lifting device support seat 243 of the transfer structure. An external crane 300, in conjunction with the lifting beam 322 of the nacelle lifting device 32, lifts the nacelle 30 and moves it above the support beam 321 to a suitable position. The crane 300 hook slowly lowers, achieving a limiting engagement between the lifting beam 322 and the support beam 321. The crane 300 gradually reduces its lifting force, ensuring that the support beam 321 of the nacelle lifting device 32 supports the entire weight of the nacelle 30. During this process, the counterweight component 25 also moves synchronously, ensuring that the center of gravity of the installation equipment 200 and the nacelle 30 remains at the center of the wind turbine generator 100 foundation throughout the entire process. The connection between the crane 300 and the nacelle 30 is then dismantled, completing the full connection between the nacelle 30 and the installation equipment 200.

[0222] Please refer to Figure 39. The first traction cable 222 is tightened synchronously by the first power device 22, which drives the entire installation platform 21 and the nacelle 30 to rise along the first direction Z and lift them to a suitable position. For example, after the space is sufficient for the nacelle lifting device 32 to move the nacelle 30 along the second direction X, the distance between the lower flange of the nacelle 30 and the upper flange of the second tower section 210b is about 100mm, and then the movement stops.

[0223] Please refer to Figure 40. Drive the nacelle spreader 32 to move along the second direction X, causing the nacelle 30 to move along the second direction X toward the second tower section 210b until the flange of the nacelle 30 and the second tower section 210b are concentric. During this process, the counterweight assembly 25 will also move synchronously toward the center of the wind turbine generator 100 foundation along the second direction X, so that the center of gravity of the assembly of the installation equipment 200 and the nacelle 30 is at the center of the wind turbine generator 100 foundation.

[0224] The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation equipment 200 and the nacelle 30 to descend in the first direction Z, so that the lower flange of the nacelle 30 coincides with the upper flange of the second tower section 210b. The nacelle 30 and the second tower section 210b are installed until all connecting bolts are tightened. During this process, as the lifting force on the nacelle 30 gradually decreases, the counterweight component 25 will also move synchronously to the appropriate position.

[0225] Please refer to Figure 41. The drive nacelle spreader 32 moves along the second direction X, moving towards the initial position. The counterweight assembly 25 will also move synchronously to ensure that the center of gravity of the installed equipment 200 is at the center of the foundation of the wind turbine generator 100.

[0226] Please refer to Figure 42. The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation platform 21 to descend along the first direction Z until the installation platform 21 lands on the tooling bracket 23, thereby completing the installation of the engine room 30.

[0227] Please refer to Figures 43 to 46. The assembly of the wheel hub 40 in step S30 can be performed according to the following steps:

[0228] Referring to Figures 43 and 44, remove the nacelle lifting device 32 from the adapter mechanism 24, install the hub lifting device 33 onto the adapter mechanism 24, and then install the hub 40 onto the hub lifting device 33. Specifically, this involves using an external crane 300 to lift the hub 40 and move it to a suitable position on the hub lifting device 33. The crane 300 hook moves slowly to connect the hub 40 to the hub lifting device 33. The crane 300 gradually reduces its lifting force, allowing the hub lifting device 33 to support the entire weight of the hub 40. During this process, the counterweight assembly 25 also moves synchronously to ensure that the center of gravity of the installation equipment 200 and the hub 40 remains at the center of the wind turbine generator 100 foundation throughout the entire process. The connection between the crane 300 and the hub 40 is then removed, completing the full connection between the hub 40 and the installation equipment 200.

[0229] Please refer to Figure 45. The first traction cable 222 is tightened synchronously by the first power device 22, which drives the entire mounting platform 21 and wheel hub 40 to rise along the first direction Z. After being raised to a suitable position, the movement stops.

[0230] Please refer to Figure 46. Drive the hub spreader 33 to move along the second direction X, which in turn moves the hub 40 towards the nacelle 30 along the second direction X until the flange of the hub 40 coincides with the flange of the nacelle 30. During this process, the counterweight assembly 25 will also move synchronously towards the center of the wind turbine generator 100 foundation along the second direction X, so that the center of gravity of the assembly of the installation equipment 200 and the hub 40 is at the center of the wind turbine generator 100 foundation.

[0231] The engine compartment 30 and wheel hub 40 are connected by bolts. After they are fully secured, the bolts connecting the wheel hub 40 and the wheel hub lifting device 33 are removed. During the entire process, the counterweight assembly 25 will also move accordingly to ensure the center of gravity of the entire installation equipment 200 meets the requirements. The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation platform 21 to descend along the first direction Z until the installation platform 21 lands on the tooling bracket 23, thereby completing the installation of the wheel hub 40.

[0232] Please refer to Figures 47 to 52. The assembly of blade 50 in step S30 can be performed according to the following steps:

[0233] Referring to Figures 47 and 48, the hub lifting device 33 is removed from the adapter mechanism 24, and the blade lifting device 34 is installed on the adapter mechanism 24. Then, the blade 50 is installed on the hub lifting device 33. Specifically, the blade 50 is lifted by an external crane 300 and moved to a suitable position on the blade lifting device 34. The crane 300 hook moves slowly to connect the blade 50 to the blade lifting device 34, and the blade lifting device 34 presses the blade 50 together via the first clamping arm 3422 and the second clamping arm 3423. The crane 300 gradually reduces its lifting force, allowing the blade lifting device 34 to support the entire weight of the blade 50. During this process, the counterweight assembly 25 also moves synchronously to ensure that the center of gravity of the installation equipment 200 and the blade 50 is at the center of the wind turbine generator 100 foundation throughout the entire process. The connection between the crane 300 and the blade 50 is then removed, completing the full connection between the blade 50 and the installation equipment 200.

[0234] Please refer to Figure 49. The first traction cable 222 is tightened synchronously by the first power device 22, which drives the entire mounting platform 21 and wheel hub 40 to rise along the first direction Z. After being raised to a suitable position, the movement stops.

[0235] Please refer to Figure 50. Through the action of the seventh drive component 343 on the blade lifter 34, the combination of the blade lifter 34 and the blade 50 is rotated to achieve the state in which the blade root flange of the blade 50 faces upward and is parallel to the flange surface of the hub 40. During the whole process, the counterweight component 25 will also move accordingly to ensure the center of gravity requirements of the entire installation equipment 200.

[0236] Please refer to Figure 51. The drive blade lifting device 34 moves along the second direction X, causing the blade 50 to move along the second direction X towards the hub 40. At the same time, the first power device 22 simultaneously tightens the first traction cable 222, causing the entire installation equipment 200 and the blade 50 to move upward along the first direction Z to the hub 40. By adjusting the blade 50, the blade 50 is installed on the hub 40. During the entire process, the counterweight component 25 will also move accordingly to ensure the center of gravity of the entire installation equipment 200 meets the requirements.

[0237] The blade 50 is connected to the hub 40 using bolts. Once fully secured, the first clamping arm 3422 and / or the second clamping arm 3423 of the blade lifting device 34 are opened to separate the blade lifting device 34 from the blade 50. During the entire process, the counterweight assembly 25 will also move accordingly to ensure the center of gravity of the entire installation equipment 200 meets the requirements.

[0238] The first traction cable 222 is released synchronously by the first power device 22, which drives the entire installation platform 21 to descend along the first direction Z until the installation platform 21 lands on the tooling bracket 23, thereby completing the installation of the first blade 50.

[0239] Referring to Figure 52, since the impeller comprises multiple blades 50, after the installation of the first blade 50 is completed, the hub 40 and blade 50 assembly can be rotated using the internal turning fixture of the wind turbine generator set 100, so that the flange of the other hub 40 to be installed is in a vertically downward position. By repeating the steps in Figures 47 to 51, the installation of the remaining blades 50 can be completed. After the assembly of all wind turbine components is completed, the installation equipment 200 is removed, thus completing the installation of the wind turbine generator set 100.
