[0032] Example 1:
[0033] Figures 1 to 6 This invention illustrates an embodiment of the alignment device for tower docking. The alignment device for tower docking in this embodiment includes an alignment rod 1 and two alignment seats 2 respectively disposed at both ends of the alignment rod 1. Two mutually perpendicular movable rods 3 are movably inserted through the alignment seats 2. The movable rods 3 are perpendicular to the alignment rod 1. Adjusting rods 4 are movably sleeved at both ends of the movable rods 3. The end of the adjusting rod 4 away from the alignment seat 2 is provided with a positioning element 6 for insertion into a threaded hole 51 on the periphery of a flange 5. The movable rod 3 is provided with a first locking element 7 for locking the adjusting rod 4, and the alignment seat 2 is provided with a second locking element 8 for locking the movable rod 3.
[0034] The process of using the alignment device for connecting the tower sections is as follows: First, as... Figure 3 As shown, insert the two mutually perpendicular movable rods 3 on the centering seat 2 at the bottom of the centering rod 1 of this centering device into the lower tower, and insert the positioning parts 6 on the adjusting rods 4 at both ends of the two movable rods 3 into the corresponding threaded holes 51 on the flange 5 on the inner wall of the upper port of the lower tower (the flange 5 has multiple threaded holes 51 evenly spaced around the center on its circumference), thereby achieving centering of the centering seat 2 at the bottom of the centering rod 1 with the lower tower, and tighten the corresponding first locking part 7 and second locking part 8; then, as... Figure 4 As shown, two mutually perpendicular movable rods 3 on the centering seat 2 at the top of the centering rod 1 are inserted into the upper tower tube, and the positioning parts 6 on the adjusting rods 4 at both ends of one movable rod 3 are respectively inserted into the corresponding threaded holes 51 on the flange 5 on the inner wall of the lower port of the upper tower tube (the flange 5 has multiple threaded holes 51 evenly spaced around the center on its circumference); as Figure 5As shown, the upper tower cylinder drives the movable rod 3 to move, and simultaneously, another movable rod 3 moves, causing the positioning parts 6 on the adjusting rods 4 at both ends of the movable rod 3 to be inserted into the corresponding threaded holes 51 on the flange 5 on the inner wall of the lower port of the upper tower cylinder, thus achieving alignment between the alignment seat 2 at the top of the alignment rod 1 and the upper tower cylinder. Tightening the corresponding first locking part 7 and second locking part 8 aligns the threaded holes 51 on the upper and lower flanges 5. Finally, bolts are screwed into the aligned threaded holes 51. This alignment device for tower docking has two advantages: firstly, it can be disassembled and reused after use, facilitating reuse and reducing operating costs; secondly, alignment can be achieved simply by moving the movable rod 3, making the alignment operation easy and efficient.
[0035] Furthermore, in this embodiment, the movable rod 3 is a square tube rod, and the adjusting rod 4 is movably inserted into the movable rod 3, and can be moved and adjusted along the length of the movable rod 3. The movable rod 3 is made of square tube, which is low in cost.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the center seat 2 has two through holes 21 that are perpendicular to each other, and two movable rods 3 on the center seat 2 are respectively inserted into the two through holes 21. The size of the through holes 21 is adapted to the movable rods 3, and they play a guiding role in the movement of the movable rods 3.
[0037] Furthermore, in this embodiment, the first locking element 7 is a locking screw, which has a simple structure. Of course, other forms of locking elements can also be used, such as a combination of a pin and a pin hole.
[0038] Furthermore, in this embodiment, the second locking element 8 is a locking screw, which has a simple structure. Of course, other forms of locking elements can also be used, such as a combination of a pin and a pin hole.
[0039] Furthermore, in this embodiment, the centering seat 2 is rotatably connected to the centering rod 1. This facilitates the rotation of the movable rod 3 to change its direction and adjust the position of the positioning member 6, making it easier to adjust each positioning member 6 to the correct position and insert it into the corresponding threaded hole 51.
[0040] Furthermore, in this embodiment, the centering seat 2 is provided with a locking member 9 for locking the centering rod 1. The locking member 9 is used to lock the centering rod 1 and the centering seat 2, and can also unlock the centering rod 1 and the centering seat 2.
[0041] Furthermore, in this embodiment, the locking element 9 is a locking screw, which has a simple structure. Of course, other forms of locking elements 9 can also be used, such as a combination of a pin and a pin hole.
[0042] Furthermore, in this embodiment, the centering rod 1, the movable rod 3, and the adjusting rod 4 are all steel rods.
[0043] Furthermore, in this embodiment, the positioning element 6 can be a positioning screw for threaded connection with the threaded hole 51. Of course, it can also be a positioning pin.
[0044] Example 2:
[0045] Figure 7 This invention illustrates another embodiment of the centering device for tower docking. The structure of the centering device for tower docking in this embodiment is basically the same as that in Embodiment 1, except that the centering rod 1 is a telescopic rod.
[0046] The centering rod 1 is a telescopic rod, such as an umbrella rod structure consisting of at least two movable sleeves, which facilitates its proximity to the upper and lower flanges 5 after centering, and is suitable for using shorter bolts to connect the upper and lower aligned threaded holes 51.
[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
