The straight line where the central axis of the first embedded bolt hole 23 is located is collinear with the straight line where the central axis of the corresponding second embedded bolt hole 231 is located. And the diameter of the first embedded bolt hole 23 is 1.2 times the diameter of the second embedded bolt 231. The embedded bolts pass through the corresponding first embedded bolt holes 23 and the second embedded bolt holes 231.

[0037] In order to prevent the embedded bolts from shifting or loosening when subjected to external forces.

[0038] A number of circular tubes 4 are fixedly arranged on the circular steel plate 22, and the number of circular tubes 4 is six. The number of circular tubes 4 is equal to the number of first embedded bolt holes 23, and the circular tubes 4 are arranged at the corresponding first embedded bolt holes 23.

[0039] The circular tubes 4 shield the corresponding first embedded bolt holes 23, and the inner hole size of the circular tubes 4 is the same as the size of the corresponding first embedded bolt holes 23.

[0040] A sleeve 8 is arranged on each circular tube 4. The vertical cross-section of the sleeve 8 is T-shaped. The small end of the sleeve 8 is inserted into the corresponding circular tube 4, and the bottom of the large end of the sleeve 8 is in contact with the top end face of the corresponding circular tube 4.

[0041] The outer diameter size of the small end of the sleeve 8 is adapted to the inner diameter size of the circular tube 4. The inner hole size of the sleeve 8 is adapted to the outer diameter size of the embedded bolt.

[0042] A rectangular tube 24 and a square tube 25 are arranged on the circular steel plate 22. The rectangular tube 24 and the square tube 25 are perpendicular to each other. Part of the rectangular tube 24 and part of the square tube 25 extend outside the corresponding circular steel plate 22.

[0054] Next, the operator places the sleeve 8 on the corresponding round pipe 4, and then passes the embedded bolt through the corresponding sleeve 8 and fixes it with a nut.

[0055] So far, the installation of the entire device body 1 is completely finished. Finally, after the device body 1 is placed in the designated position.

[0056] When disassembling the device body 1, the operator first separates the nut from the embedded bolt.

[0057] Then, the sleeve 8 is taken out.

[0058] Next, the operator takes out the entire device body 1.

[0059] Finally, after the operator uses a tool to take out the bolts connecting the two connecting plates 6, the entire device body 1 is divided into four separate installation modules 2, and the four installation modules 2 are lifted to appropriate positions by a lifting device.
