A plurality of groups of support mechanisms that are rotatably distributed are arranged at the top of the circular seat 1, and the support mechanisms are used to improve the stability of the natural gas pipeline during docking; the support mechanism includes a plurality of first support rods 101, a rotating rod 102 is connected to the top of the first support rod 101, a second support rod 103 is connected to the top of the rotating rod 102, a plurality of concave blocks 104 that are rotatably distributed are fixed to the top of the circular seat 1, a circular ring 201 is fixedly connected to the outer side of the support column 2, and the top of the second support rod 103 is inserted into the groove 20 opened in the circular ring 201. 2, a movable shaft 105 is provided on the first support rod 101 and the second support rod 103, and the movable shaft 105 extends out of the first support rod 101 and both ends are fixedly connected to the inner side of the concave block 104, and the other movable shaft 105 extends out of the second support rod 103 and both ends are fixedly connected to the inner wall of the groove 202; a threaded rod 106 is fixedly connected to the bottom of the rotating rod 102, and the threaded rod 106 is screwed into the first threaded groove 107 opened in the first support rod 101, and a rotating groove 108 is opened in the second support rod 103, and a rotating plate 109 is provided in the rotating groove 108, and a first connecting rod 110 is fixedly connected inside the rotating groove 108 and located at the bottom of the rotating plate 109, and the first connecting rod 110 extends out of the bottom end of the second support rod 103 and is fixedly connected to the top of the rotating rod 102.

[0024] Through the above technical solution, the circular seat 1 is placed on the ground, and a fixing hole is opened on the circular seat 1 for fixing the circular seat 1 on the ground. When the support column 2 supports the natural gas pipeline, the rotating rod 102 is rotated, so that the rotating rod 102 drives the threaded rod 106 to rotate in the first thread groove 107. The threaded rod 106 can be moved to the outside of the first support rod 101 through the screw connection between the threaded rod 106 and the first thread groove 107, so that the threaded rod 106 squeezes the rotating rod 102 and the second support rod 103, and then the second support rod 103 is connected to the second support rod 101. 03 can squeeze the circular ring 201 on the outside of the support column 2.

By squeezing the circular ring 201, the support column 2 is less likely to shake when supporting the natural gas pipeline, and is more stable, thereby making the natural gas pipeline more stable when docking, and improving the docking quality of the natural gas pipeline to a certain extent. Through the cooperation of the rotating plate 109 and the first connecting rod 110, the rotating rod 102 can rotate normally at the bottom end of the second support rod 103.

[0025] Reference Figure 1 A threaded adjustment column 301 is fixedly connected to the bottom of the rotating column 3. The threaded adjustment column 301 is screwed into the second thread groove 203 opened in the supporting column 2. The rotating column 3 is rotated, and the threaded adjustment column 301 is driven to rotate in the second thread groove 203 through the rotating column 3. The threaded adjustment column 301 is screwed with the second thread groove 203, so that the threaded adjustment column 301 moves upward and drives the rotating column 3 and the fixed column 4 to move upward, so that the use height of the clamping mechanism can be adjusted, so that the support height of the natural gas pipeline can be adjusted according to the different docking heights of the natural gas pipeline.

[0026] Reference Figure 1 and Figure 6 A collar 302 is fixed on the outside of the rotating column 3, and a limiting ring 303 is fixedly connected to the inside of the collar 302. The limiting ring 303 is rotatably connected to the inside of the limiting groove 401 opened in the fixed column 4. After the height of the clamping mechanism is adjusted, the two clamping mechanisms may not correspond to each other, so that the fixed column 4 and the clamping mechanism can be rotatably held so that the two clamping mechanisms correspond to each other, thereby facilitating the clamping and fixing of the natural gas pipeline. Moreover, through the cooperation of the collar 302 and the limiting ring 303, the rotating column 3 and the fixed column 4 can be connected together, so that the fixed column 4 can rotate normally at the top of the rotating column 3.

[0027] Reference Figure 1 and Figure 4The clamping mechanism includes a supporting ring 402 and a clamping ring 403. The bottom of the supporting ring 402 is fixedly connected to the top of the fixed column 4. A rotating shaft 404 is provided on one side of the top of the supporting ring 402. The supporting ring 402 and the clamping ring 403 are rotatably connected through the rotating shaft 404. The natural gas pipeline is placed on the top of the supporting ring 402, and the clamping ring 403 is rotated so that the clamping ring 403 clamps the natural gas pipeline. Through the cooperation between the supporting ring 402 and the clamping ring 403, the natural gas pipeline can be clamped and fixed.

[0028] Reference Figure 1 , Figure 4 and Figure 5 A connecting plate 405 is fixedly connected to one side of the supporting ring 402 and one side of the clamping ring 403. A U-shaped fixing frame 406 is inserted on the outside of the two connecting plates 405. A T-shaped limiting plate 407 is arranged on the top of the U-shaped fixing frame 406. A first plug hole 408 and a second plug hole 409 are respectively opened inside the U-shaped fixing frame 406 and inside the connecting plate 405. The bottom end of the T-shaped limiting plate 407 passes through the first plug hole 408 and the second plug hole 409 in sequence and extends to the bottom of the U-shaped fixing frame 406. When the supporting ring 402 and the clamping ring 403 are fixed to the natural gas pipeline, the U-shaped fixing frame 406 is inserted on the outside of the two connecting plates 405, and then the bottom end of the T-shaped limiting plate 407 is passed through the first plug hole 408 and the second plug hole 409 in sequence. Through the cooperation of the U-shaped fixing frame 406 and the T-shaped limiting plate 407, the two connecting plates 405 can be fixed together, and then the supporting ring 402 and the clamping ring 403 are fixed together, making it more stable when fixed to the natural gas pipeline.

[0029] The implementation principle of an auxiliary device for docking and installation in an embodiment of the utility model is as follows: by adopting a supporting mechanism, the circular seat 1 is placed on the ground, and a fixing hole is opened on the circular seat 1 for fixing the circular seat 1 on the ground. When the support column 2 supports the natural gas pipeline, the rotating rod 102 is rotated, so that the rotating rod 102 drives the threaded rod 106 to rotate in the first thread groove 107. The threaded rod 106 can be moved to the outside of the first support rod 101 through the screw connection between the threaded rod 106 and the first thread groove 107, so that the threaded rod 106 can squeeze the rotating rod 102 and the second support rod 103, and then the circular ring 201 outside the support column 2 can be squeezed through the second support rod 103. Similarly, the remaining groups of supporting mechanisms can be adjusted, and the circular ring 201 can be squeezed by several supporting mechanisms. By squeezing the circular ring 201, the support column 2 is not easy to shake when supporting the natural gas pipeline, and is more stable, thereby making the natural gas pipeline more stable when docking, and improving the docking quality of the natural gas pipeline to a certain extent.
