[0026] To make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.
[0027] Please refer to Figures 1-6 The present utility model is an above-ground natural gas pipeline anti-seismic support, which comprises:
[0028] The anti-seismic module comprises a base 11 and a hydraulic shock absorber 12, and the hydraulic shock absorber 12 is screw-connected to the central position on the upper end of the base 11.
[0029] The base 11 provides an installation environment and ensures the stability of the structure, and the hydraulic shock absorber 12 can perform shock absorption treatment on the stressed gas pipeline by utilizing the intermolecular force between the internal oil and the friction force between the oil hole.
[0030] The base 11 is provided with threaded holes at equidistant positions on the edge, and the surface of the lower end of the base 11 is provided with anti-skid lines.
[0031] The threaded holes are inserted into bolts and tightened to fix the base 11, and the anti-skid lines can improve the structural stability by increasing the friction force between the contact surfaces.
[0032] The anti-vibration module also includes a helical damping spring 13 and a collar 14. The lower end of the helical damping spring 13 is fixed to the outer edge of the upper end of the hydraulic damper 12, and the upper end abuts against the inner side of the collar 14. The collar 14 is sleeved on the upper part of the outer surface of the hydraulic damper 12.
[0033] The helical damping spring 13 provides cushioning by utilizing the counterforce applied by the restoring deformation, and is used for mounting the abutment ring 36 structure described below via the collar 14.
[0034] The docking module includes a first docking clip 21 and a second docking clip 24. The first docking clip 21 and the second docking clip 24 are respectively snapped onto the upper and lower ends of one side of the outer surface of the gas pipeline. A docking block 22 is fixed in the middle of one end of the first docking clip 21 and the second docking clip 24. The lower part of the docking block 22 at one end of the first docking clip 21 is sleeved with the upper end of the hydraulic shock absorber 12. A docking post 23 is provided through the middle of the first docking block 22 and the second docking block 22. A limiting ring 25 is sleeved at the end of the docking block 22.
[0035] The first docking clamp 21 and the second docking clamp 24 are used to facilitate the installation between the gas pipeline and the hydraulic shock absorber 12. The first docking clamp 21 and the second docking clamp 24 are connected by the docking column 23, which can be used to guide the docking between connected gas pipelines. The docking block 22 is used for docking transition. The limiting ring 25 ensures the tightness of the connection between the first docking clamp 21 and the second docking clamp 24 and the gas pipeline when the first docking clamp 21 and the second docking clamp 24 are in the up and down state.
[0036] Working principle: During the vibration reduction treatment of the gas pipeline, the first docking clamp 21 and the second docking clamp 24 are respectively clamped on the upper and lower positions of one side of the outer surface of the gas pipeline, and the limiting ring 25 is sleeved on the end of the docking block 22. The gas pipeline is connected to the hydraulic shock absorber 12. The internal molecular force between the oil inside the hydraulic shock absorber 12 and the friction force between the oil hole after the hydraulic shock absorber 12 is subjected to force provide the vibration reduction required for the gas pipeline. During the docking guidance of the gas pipeline, the first docking clamp 21 and the second docking clamp 24 are set horizontally and fixed by the docking post 23. They are then clamped to the lower part of the gas pipeline to be docked.
[0037] This solution meets the requirements for vibration reduction and docking guidance of gas pipelines, eliminating the need for manual support or other additional support tools, saving time and effort, and improving structural applicability and functionality, making it convenient to use.

[0040] The top end of the isolation cover 35 is higher than the top end of the hydraulic shock absorber 12, and the inner wall of the isolation cover 35 is arranged in a gap with the outer wall of the hydraulic shock absorber 12.
[0041] The isolation module further comprises a threaded ring 31, and the threaded ring 31 is fixed on the outer edge of the middle part of the base 11, and the lower part of the outer surface of the movable frame 32 is screwed into the threaded ring 31;
[0042] The threaded ring 31 installs the structure of the movable frame 32.
[0043] Working principle: during use of the above-mentioned hydraulic shock absorber 12, after the gas pipeline is subjected to vibration force, the force is transmitted to the contact ring 36, the contact ring 36 transmits the force to the isolation cover 35 and then to the movable spring 34, at this time, the movable spring 34 is in a compressed state, the linkage isolation cover 35 extends into the movable cavity 33, and after the force is released, the movable spring 34 restores the deformation to make the isolation cover 35 restore the original state, and the hydraulic shock absorber 12 is always externally isolated and protected.
