The top seat body 3 extends inside; two long strip openings are arranged on the top of the box body 1 along the pipeline laying direction, the vertical plate of the L-shaped support plate passes through the long strip opening, and the horizontal plate of the L-shaped support plate is inserted into the gap formed by the top plate and the bottom plate on the corresponding side of the bottom seat body 2; a shock-absorbing layer 4 is arranged between the bottom plate and the horizontal plate, and between the horizontal plate and the top plate; a sliding layer 5 is arranged between the top of the box body 1 and the top support plate; movable connecting plates 6 are respectively arranged at both ends of the box body 1, the lower part of the movable connecting plate 6 is fixedly connected to the box body 1, and the upper part of the movable connecting plate 6 is slidably connected to the top support plate, and the sliding direction is parallel to the laying direction of the pipeline 7.

[0020] The box body 1, the bottom seat body 2, the top seat body 3, and the movable connecting plate 6 are all made of steel plates.

[0021] The shock absorbing layer 4 is composed of shock absorbing materials and / or shock absorbing elements. The shock absorbing materials include high elastic rubber, and the shock absorbing elements include shock absorbing springs.

[0022] The sliding layer 5 is composed of a sliding material, and the sliding material includes polytetrafluoroethylene.

[0023] like Figure 3 , Figure 4 As shown, a boss 9 is provided at the lower part of the movable connecting plate 6, and the surface of the boss 9 is in direct contact with the outer surface of the box body 1; a bolt hole 10 is provided on the boss 9, and a bolt hole 10 is provided on the upper part of the movable connecting plate 6, and the bolt hole 10 is a smooth hole; threaded holes are provided at both ends of the box body 1 and the top support plate at the corresponding connection respectively; the head of the connecting bolt 8 passes through the bolt hole 10 and is fixed in the threaded hole; a sliding gap is left between the movable connecting plate 6 and the top support plate, and the gap is equal to the height of the boss 9 and is 10 to 20 mm.

[0024] The diameter of the pipeline 7 is less than or equal to DN300.

[0025] The multi-layer sliding shock-absorbing pipeline support described in the present invention is suitable for pipeline installation projects below DN300 that require shock absorption and expansion compensation, and its specific size is determined according to the model of the pipeline.

[0026] The top seat body 3 is made of steel plate and mainly plays the role of supporting the pipeline 7, that is, it is used as a pipe support.

[0027] The sliding layer 5 is made of polytetrafluoroethylene material, and is used to achieve axial sliding of the top seat body 3 relative to the bottom seat body 2. Polytetrafluoroethylene as a sliding material has the following characteristics: 1) small friction coefficient; 2) static friction coefficient is smaller than dynamic friction coefficient; 3) resin migrates into the sliding material matched with it, forming sliding between polytetrafluoroethylene and polytetrafluoroethylene; 4) stable to almost all chemicals; 5) good high temperature and low temperature resistance (-250℃~260℃); 6) non-thermoscopic material, water absorption rate is below 0.01%.

[0028] The movable connecting plate 6 serves as a connection between the top seat body 3 and the box body 1 and has a certain sliding range. It can compensate for the expansion and contraction of the pipeline 7 and also limit the range of movement of the top seat body 3 .

[0029] The bottom seat body 2 is mainly matched with the top seat body 3 to realize setting two shock-absorbing layers 4 between the two, thereby indirectly playing a supporting role.

[0030] The shock absorbing layer 4 plays a shock absorbing role.

[0031] The box body 1 has a sealing and protective effect on the bottom seat body 2 and the shock-absorbing layer 4, and the bottom of the box body 1 is seated on the pipeline support.

[0032] The multi-layer sliding shock-absorbing pipe support of the present invention is arranged between the pipe 7 and the pipe support along the laying direction of the pipe 7, the weight of the pipe 7 is applied to the top seat body 3, the gravity of the top seat body 3 and the pipe 7 is transmitted to the bottom seat body 2 through the shock-absorbing layer 4, and the shock-absorbing layer 4 plays a shock-absorbing role on the pipe 7. When the pipe 7 is axially expanded and deformed due to temperature changes, since the top seat body 3 can slide relative to the box body 2 and the bottom seat body 2, this part of the expansion and contraction can be well compensated.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
