[0002] In recent years, my country's wind power has developed rapidly, and the power and hub center of wind turbines have continued to rise, which has also caused the size of towers and rigs to become larger and larger. Problems such as the large size, heavy weight, and difficulty in transportation of towers and rigs have arisen, and a new process of segmented towers and rigs has been proposed. The segmented tower rig is a tower that is disassembled into several parts, and each piece is connected by bolts. It is only necessary to transport the segmented tower rig to the site and then assemble it into a whole to solve the problems of volume, weight, transportation, etc. of traditional towers. During the assembly process, the segmented tower needs to be turned over and aligned. Most of the existing segmented tower assembly tooling is fixed, which cannot be used for tower sections of different diameters, and it is not convenient to adjust the angle of the segments during the assembly process.

However, it is apparent that one or more embodiments can be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0048] As shown in Figures 1-2, the universal ground assembly equipment for a segmented tower designed in the present invention includes a flange-end support frame 1 and a tower-end support frame 2 arranged in parallel along the length of the tower. The flange-end support frame 1 includes a first base 11, with a first fixed support seat 13 disposed at the first end of the first base 11, and a first sliding support seat 12 symmetrical to the first fixed support seat 13 disposed at the second end of the first base 11. The first sliding support seat 12 is slidably connected to the first base 11 to adjust the spacing between the first sliding support seat 13 and the first fixed support seat 13 to accommodate segments of different diameters.

[0049] A first height adjustment support assembly 14 is provided between the first sliding support seat 12 and the first fixed support seat 13. The first height adjustment support assembly 14 can fine-tune the height of the slices installed thereon in the vertical direction to ensure that the heights of the slices on the left and right sides are adapted when assembled. A first angle adjustment support assembly 15 is assembled on the first sliding support seat 12. A second angle adjustment support assembly 16 is assembled on the end of the first fixed support seat 13 away from the first height adjustment support assembly 14. The first angle adjustment support assembly 15 and the second angle adjustment support assembly 16 respectively adjust the side angles of the slices installed thereon from both ends. A first fixed height support frame 17 is assembled on the end of the first fixed support seat 13 close to the first height adjustment support assembly 14. A flange end flip support frame 3 is provided on the side of the first base 11 close to the second angle adjustment support assembly 16.

[0050] In this embodiment, the tower end support frame 2 includes a second base 21, a second fixed support seat 23 is set on the first end of the second base 21, and a second sliding support seat 22 symmetrical to the second fixed support seat 23 is set on the second end of the second base 21. The second sliding support seat 22 is slidably connected to the second base 21 to adjust the distance between it and the second fixed support seat 23. A second height adjustment support assembly 24 is provided between the second sliding support seat 22 and the second fixed support seat 23. A third angle adjustment support assembly 25 is mounted on the second sliding support seat 22. A fourth angle adjustment support assembly 26 is mounted on the end of the second fixed support seat 23 away from the second height adjustment support assembly 24. A second fixed height support frame 27 is mounted on the end of the second fixed support seat 23 near the second height adjustment support assembly 24. A first semi-ring support member 5 is connected between the third angle adjustment support assembly 25 and the second height adjustment support assembly 24. A second semi-ring support member 6 is connected between the fourth angle adjustment support assembly 26 and the second fixed height support seat 22. The first semi-ring support member 5 and the second semi-ring support member 6 are arranged opposite each other. The first semi-ring support member 5 and the second semi-ring support member 6 are respectively adjusted in rotation angle by the third angle adjustment support assembly 25 and the fourth angle adjustment support assembly 26 to adjust the placement posture of the segmented tower end. A bottom gap adjustment assembly 7 is provided at the bottom intersection of the two. A tower end flip support frame 4 is provided on the end of the second base 21 near the fourth angle adjustment support assembly 26. The flange end flip support frame 3 and the tower end flip support frame 4 are used to cooperate with the crane 8 to lift the segments for flipping and rotation.

[0051] As shown in Figure 2, during specific implementation, the first angle adjustment support assembly 15, the second angle adjustment support assembly 16, the third angle adjustment support assembly 25 and the fourth angle adjustment support assembly 26 are all provided with a telescopic rod mounting seat and a telescopic rod, and the telescopic rod is rotatably set on the telescopic rod mounting seat, and the telescopic rod is used to rotate the support segment to adjust the side lying angle of the segment.

[0052] As shown in Figure 3, it is a schematic diagram of the overall structure of the bottom end gap adjustment component of the present invention. The bottom end gap adjustment component 7 includes four groups of adjustment arms 71, an intermediate connecting rod 72, a pair of adjustment shafts 73, an adjustment connecting rod 74 and a connecting shaft 75. The four groups of adjustment arms 71 are combined in pairs and aligned. The inside of each two groups of adjustment arms 71 is connected with an adjustment shaft 73, an intermediate connecting rod 72 and a connecting shaft 75 in sequence from top to bottom. A pair of connecting shafts 75 are respectively used to be fixedly connected to the bottom of the frame of the segmented tower tower fixed on the first semi-ring support member 5 and the second semi-ring support member 6. An adjustment connecting rod 74 is arranged between each two groups of adjustment arms 71. The two ends of the adjustment connecting rod 74 are respectively threadedly connected to a pair of relative adjustment shafts 73, and the gap between the two is adjusted by rotating the adjustment shaft 73.

[0053] As shown in Figure 5, it is a flowchart of the assembly process of the universal ground assembly equipment for the segmented tower frame of the present invention. The three segments are hoisted to the flange end support frame 1 and the tower end support frame 2 in sequence by a crane, and the placement of the segment flange end is adjusted by the first angle adjustment support assembly 15 and the second angle adjustment support assembly 16 in sequence. The placement of the segment tower end is adjusted by the third angle adjustment support assembly 25 and the fourth angle adjustment support assembly 26 so that the positions of the two sides are adapted. The gap between the segments on both sides is then adjusted by the bottom end gap adjustment assembly 7 to ensure the spacing during assembly. Finally, the segment at the top is hoisted by a crane 8, and is turned over and rotated in conjunction with the side flange end flip support frame 3 and the tower end flip support frame 4, and finally hoisted to the top of the segments on both sides to complete the overall assembly.

[0054] In summary, the universal ground assembly equipment for segmented towers designed in this invention allows for the forward and backward and vertical adjustment of the segmented tower as a whole, while also meeting the requirements for installation angle adjustment and tower frame docking and fixation. The invention also incorporates a bottom-end gap adjustment assembly to facilitate adjustment of the spacing between the two side towers when docking the towers, resulting in simpler operation, greater stability, and higher efficiency.

[0055] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
