[0014] As shown in the accompanying drawings, the utility model is a FPSO process module piping anti-vibration support, comprising a pipe fixing support 2 and a pipe anti-vibration support 3, wherein the pipe fixing support 2 and the pipe anti-vibration support 3 are fixedly connected via a support connecting plate 4, wherein the pipe fixing support 2 comprises a U-shaped pipe fixing frame 2-1, and the pipe 1 is fixed to the lower base plate of the U-shaped pipe fixing frame via a fixing device.
[0015] The pipeline shockproof support 3 includes a U-shaped pipeline shockproof frame 3-1, a lower V-shaped block 3-3 is fixed in the middle of the bottom plate of the U-shaped pipeline shockproof frame 3-1 (can be bolted), an upper V-shaped block 3-2 is arranged above the lower V-shaped block 3-3, and a plurality of bolt holes 3-9 are arranged at intervals on the upper and lower sides of the two side plates of the U-shaped pipeline shockproof frame 3-1, and the left and right ends of a mounting plate 3-6 arranged in the horizontal direction pass through the bolt holes at predetermined positions and are fixedly connected to the two side plates of the U-shaped pipeline shockproof frame 3-1, and two through holes are opened on the mounting plate 3-6, and the lower parts of the two connecting shafts 3-7 arranged in the vertical direction respectively pass through the mounting plate 3- The through hole on 6 is threadedly connected with the bolt hole opened on the top of the upper V-shaped block 3-2 and fixed by bolts. The connecting shaft 3-7 is slidably connected with the through hole on the mounting plate 3-6. The upper part of each connecting shaft 3-7 is fixedly connected with a limiting plate 3-8. The limiting plate 3-8 can prevent the connecting shaft 3-7 from falling through the through hole. A main spring 3-5 is sleeved on each connecting shaft 3-7 between the mounting plate 3-6 and the upper V-shaped block 3-2. The left and right side walls of the upper V-shaped block 3-2 are respectively fixedly connected to the lower end of a side spring 3-4, and the upper end of the side spring 3-4 is fixedly connected to the side plate adjacent to the U-shaped pipe shockproof frame 3-1. The mounting plate 3-6 can be adjusted up and down according to the position of the bolt hole 3-9, so that the main spring 3-5 is in a compressed state, and the pipeline 1 is set through the gap between the lower V-block 3-3 and the upper V-block 3-2. The main spring 3-5 in the compressed state makes the pipeline 1 pressed tightly between the V-block 3-2 and the lower V-block 3-3.

[0018] Here’s how it works:
[0019] First, as required, each U-shaped pipe fixing frame 2-1 and the U-shaped pipe shockproof frame 3-1 fixed with the lower V-shaped block 3-3 are hoisted at the designated position, and the U-shaped pipe fixing frame 2-1 and the U-shaped pipe shockproof frame 3-1 are connected with the bracket connecting plate 4, and then the pipe 1 is placed on the installed bracket, and the pipe 1 is fixed to the lower bottom plate of the U-shaped pipe fixing bracket 2-1 with the U-shaped bolt 2-2, and then the upper part of the upper V-shaped block 3-2 is connected to the connecting shaft 3-7, and the main spring 3-5 is sleeved on the connecting shaft 3-7, pass the connecting shaft 3-7 through the through hole of the mounting plate 3-6, and then fix the limit plate 3-8 on the upper part of the connecting shaft 3-7 with bolts, and then adjust the mounting plate 3-6 to a proper position between the two side plates of the U-shaped pipe shockproof bracket 3-1 and fix it, so that the main spring 3-5 is in a compressed state, and the upper V-shaped block 3-2 and the lower V-shaped block 3-3 are pressed against the pipe 1 through the main spring 3-5, and finally, the side spring 3-4 is tilted and fixed between the upper V-shaped block 3-2 and the side plate of the U-shaped pipe shockproof bracket 3-1. When the pipeline is impacted and vibrated by the harsh offshore environment, the main spring 3-5 can absorb the longitudinal vibration, and the side spring 3-4 can absorb the lateral and longitudinal vibration, thereby realizing the absorption of vibration in all directions and improving the safety and stability of the pipe bracket.
