[0001] The utility model relates to the technical field of wind power tower installation, in particular to a fragment-adjustable tower support device. Background Art

[0002] When lattice wind turbine towers are assembled and hoisted individually, they are prone to flexure and deformation due to the imbalance between their own weight and external hoisting forces. This can cause displacement and change in the spacing between the main columns, resulting in large errors in the docking between the upper and lower sections. This complicates and makes subsequent corrections complex and difficult, increasing construction costs and impacting the overall project schedule. Furthermore, deformation can lead to cumulative errors in the tower's verticality, ultimately resulting in excessively high values. During operation, the unit is subject to the long-term effects of wind loads, temperature stress fluctuations, and other factors, making the tower more susceptible to stability issues and even safety accidents.

[0003] The conventional method for supporting a lattice wind turbine tower is to directly weld a support rod between two lattice tower columns to support the lattice tower. However, this method requires selecting a support rod of appropriate length and cannot be adjusted according to the distance between the two lattice tower columns. Utility Model Content

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example

[0037] This embodiment provides an adjustable tower support device, such as Figures 1 to 4 As shown, it comprises a connecting base 1 and a connecting rod structure 2. Two connecting bases 1 are provided, symmetrically arranged, and can be mounted on two lattice tower columns to be supported, or one on a lattice tower column and the other on the ground. The connecting rod structure 2 is installed between the two connecting bases 1 and includes an intermediate connecting rod assembly, a transfer connecting rod 22, and an adjustment connecting rod 21. To ensure structural strength, the connecting base 1, the intermediate connecting rod assembly, the transfer connecting rod 22, and the adjustment connecting rod 21 are all made of metal steel.

[0038] Specifically, the entire adjustable tower support device is fixed with: a connecting seat 1, an adjusting link 21, a transfer link 22, an intermediate link assembly, a transfer link 22, an adjusting link 21 and a connecting seat 1 in sequence.

[0039] like Figure 1 As shown, the connecting seat 1 includes: a base plate 11 and a first connecting part 12. A slot is provided on the base plate 11. A first connecting part 12 is welded and installed at one end of the base plate 11 close to the connecting rod structure 2. The first connecting part 12 is a mounting tube including an internal threaded mounting hole. The opening of the internal threaded mounting hole faces away from the slot to avoid interference during subsequent installation.

[0040] like Figures 1 to 4 As shown, both ends of the adjustment link 21 are welded with a second connection portion 211, which is a screw. The second connection portion 211 is adapted to the first connection portion 12 and can be rotated and inserted into the first connection portion 12 to securely mount the adjustment link 21 on the connecting base 1. The end of the transfer link 22 close to the adjustment link 21 is welded with a third connection portion 221, which is a hollow rod. The third connection portion 221 is a nut that is adapted to the second connection portion 211. The end of the adjustment link 21 close to the transfer link 22 can be inserted into the third connection portion 221 to secure the adjustment link 21 and the transfer link 22. A fourth connecting portion 222 is welded to one end of the transfer link 22 that is away from the transfer link 22 and close to the intermediate link 23, and a fifth connecting portion 231 is welded to both ends of the intermediate link 23. The fourth connecting portion 222 and the fifth connecting portion 231 are flanges that adapt to each other. The fourth connecting portion 222 and the fifth connecting portion 231 cooperate with each other to fix the two flanges that fit together by inserting bolts into the flange holes to fix the transfer link 22 and the intermediate link assembly.

[0041] Through the above structure, such as Figures 1 to 4As shown, the transfer link 22, adjustment link 21, and connecting base 1 are installed on both sides of the intermediate link assembly. The installation is described using one side as an example. Bolts are inserted into the flange holes to install the transfer link 22 on one side of the intermediate link assembly. The second connection portion 211 of the adjustment link 21, which is close to the third connection portion 221, is then aligned with the third connection portion 221 and rotated and inserted to secure the adjustment link 21 to the transfer link 22. The second connection portion 211 of the adjustment link 21, which is close to the first connection portion 12, is then aligned with the first connection portion 12 and rotated and inserted to secure the connecting base 1 and the adjustment link 21, thereby forming a complete adjustable tower support device. The entire adjustable tower support device is installed on the lattice tower column through the notches on the connecting bases 1 at both ends to support the lattice tower column. This effectively solves the problem that when a lattice wind turbine tower is assembled and hoisted in a modular manner, it is often prone to flexure deformation due to the imbalance between its own weight and external hoisting force. The main column spacing shifts, resulting in large docking errors between the upper and lower sections, and subsequent correction work becomes complicated and difficult. It can adapt to various adverse working conditions or environmental factors during the hoisting process, maintain high-precision construction, and help simplify the installation process, saving installation time and labor costs.

[0042] Furthermore, by disassembling an adjustable tower support device into several short, assembleable parts, the device is easy to transport, not easily deformed, and has a high turnover rate. The modular design allows for easy replacement of any component if it becomes defective or even damaged, thus reducing operating costs.

[0043] When installing the adjusting link 21, Figure 1 As shown, it is also necessary to ensure that there is a gap between the main body of the adjusting link 21 and the first connecting portion 12, and to ensure that there is a gap between the main body of the adjusting link 21 and the transfer link 22. With the above arrangement, when fine pitch adjustment is required, the distances between the main body of the adjusting link 21 and the first connecting portion 12 and the transfer link 22 can be adjusted by rotating the adjusting link 21 to adapt to the use of fine pitch changes.

[0044] Furthermore, the intermediate link assembly includes at least one intermediate link 23. Different numbers of intermediate links 23 can be installed along its axial direction to form intermediate link assemblies of varying lengths. The dimensions of each intermediate link 23 are standard and can be the same or different. By increasing the number of intermediate links 23 of standard dimensions or customizing intermediate links 23 of varying dimensions, wide spacing can be achieved, thereby adapting to different diagonal spacings between lattice tower columns.

[0045] In other possible implementations, such as Figure 1 and Figure 2As shown, the sidewalls of the adjustment link 21 are also equipped with at least one lifting lug 212. After a single lattice segment is hoisted, the left and right adjustment links 21 can be rotated out of the first connection portion 12 and connected to the lifting straps via the lifting lugs 212. This allows for quick removal of the adjustment link 21, transition link 22, and intermediate link 23, facilitating subsequent installation of the lattice tower. This provides excellent safety and convenient construction. Installation and removal can be completed on a temporary construction platform for the columns. The lifting lugs 212 connect to the lifting straps to prevent them from falling during installation and removal.

[0046] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
