Using a natural gas pipeline to transport natural gas is a way to transport a large amount of natural gas on land. In municipal gas engineering, gas pipelines are generally buried underground through a positioning device to prevent the pipeline from moving, which may cause cracks in the pipeline, avoid leakage, and ensure normal gas transportation.

With the cooperation of a detachable first semi-circular hoop and a second semi-circular hoop, the device is quick and convenient for pipeline installation and positioning, and the positioning is firm and reliable. In addition, when the first semi-circular hoop or the second semi-circular hoop is damaged, it can be replaced without discarding the whole, saving resources.

[0004] However, the existing gas pipeline positioning devices mostly reuse equipment when installing gas pipelines. This requires the positioning device to have a function of being easily disassembled after use.

A U-shaped clamp 300 for clamping the upper end of the pipe is provided at the top of the outer wall of the fixing seat 100 and above the arc-shaped support groove. The top of the inner wall of the U-shaped clamp 300 abuts against the top of the outer wall of the pipe. The U-shaped clamp 300 can be pressed downward from the top of the pipe, so that the upper and lower ends of the pipe can be clamped and fixed in cooperation with the arc-shaped support groove, and then the pipe can be fixed on the fixing seat 100. The top of the outer wall of the fixing seat 100 and the positions corresponding to the two ends of the U-shaped clamp 300 are provided with installation The U-shaped clamp 300 is provided with a slot 120, and both ends of the U-shaped clamp 300 are slidably connected to the inner wall of the corresponding installation slot 120. The installation slot 120 is provided to facilitate personnel to connect the U-shaped clamp 300 with the top of the fixing seat 100, so as to fix the pipeline. The outer wall on the opposite side of the U-shaped clamp 300 is provided with a side fixing slot 310. The outer wall on the opposite side of the two fixing seats 100 and the corresponding position of the side fixing slot 310 are provided with a fixing screw hole 140. The multiple fixing screw holes 140 are evenly arranged in a strip array, and the inner walls of the fixing screw holes 140 are threadedly connected. The threaded rod 130 is connected to the fixing screw hole 140 for threading the threaded rod 130 on both sides of the outer wall of the fixing seat 100. The end of the threaded rod 130 away from the fixing seat 100 is fixed with a rotating handle, and the rotating handle can drive the threaded rod 130 to rotate. The end of the threaded rod 130 inserted into the installation slot 120 is rotatably connected with a locking block 131, and the locking block 131 abuts against the inner wall of the side fixing slot 310. Specifically, when the U-shaped clamp 300 is inserted into the installation slot 120 and the top of the pipe is pressed, the personnel can rotate The threaded rod 130 is rotated by turning the handle so that the threaded rod 130 can push the locking block 131 to be inserted into the inner wall of the side fixed slot 310, and the inserted U-shaped clamp 300 is fixed by the friction between the locking block 131 and the inner wall of the side fixed slot 310. The locking block 131 and the side fixed slot 310 need to have a high friction coefficient to ensure the clamping effect of the locking block 131 on the inner wall of the side fixed slot 310. Specifically, steel, silicon carbide ceramics, polyimide materials, etc. can be used, or patterns can be provided to improve the friction effect.

[0025] Anti-slip pads 400 for supporting the pipeline are fixed to the inner walls of the arc-shaped support grooves. The anti-slip pads 400 are provided to improve the protection effect on the bottom end of the pipeline. Bottom support blocks 200 are provided at the bottom ends of the outer walls of the fixing seats 100. Installation pins 220 are fixed to the opposite sides of the top ends of the outer walls of the bottom support blocks 200. Installation jacks are provided at the positions corresponding to the installation pins 220 on the bottom ends of the outer walls of the fixing seats 100. The outer walls of the installation pins 220 are connected to the inner walls of the installation jacks. The bottom support blocks 200 provided can be connected to the installation jacks through the installation pins 220, so that the bottom support blocks 200 can be used to support instead of the bottom ends of the outer walls of the fixing seats 100. Square embedding grooves are provided at the bottom ends of the outer walls of the bottom support blocks 200. Lifting blocks 210 are provided on the inner walls of the square embedding grooves. The square embedding grooves are provided to install the lifting blocks 210 at the bottom ends of the bottom support blocks 200. The lifting blocks 210 provided can lift the heights of the fixing seats 100 and the bottom support blocks 200, so that the height of the arc-shaped support groove can be adjusted according to the installation height of the gas pipeline, ensuring that the device can keep the gas pipeline in an aligned state during the butt joint installation of the gas pipeline and improving the positioning accuracy.

[0026] The use process of the utility model is as follows: First, the two fixing seats 100 can be placed in alignment in the gas pipeline installation area. Then, before placing, the installation pins 220 on the bottom support blocks 200 can be inserted into the installation jacks. Then, according to the installation height of the gas pipeline, the lifting blocks 210 can be clamped in the square embedding grooves to make the arc-shaped support groove flush with the bottom end of the gas pipeline. Then, the assembled fixing seats 100 can be placed in a suitable position by the personnel, and the bottom support blocks 200 and the lifting blocks 210 can be placed on the installation surface. Then, the gas pipeline to be installed can be placed on the arc-shaped support groove by the personnel, so that the anti-slip pads 400 are in contact with the bottom end of the outer wall of the gas pipeline. Then, the U-shaped chuck 300 can be taken out and inserted downward from the upper end of the gas pipeline into the installation slot 120, so that the U-shaped chuck 300 presses and fixes the gas pipeline from the top end. After the U-shaped chuck 300 is inserted, the personnel can rotate the handle to rotate the threaded rod 130, so that the threaded rod 130 drives the locking block 131 to move towards the inner wall of the side fixing groove 310 through the cooperation of the threaded connection with the fixed screw hole 140, so that the end wall of the locking block 131 abuts against the inner wall of the side fixing groove 310. In this way, the cooperation of the fixing seat 100 and the U-shaped chuck 300 can complete the fixing of the gas pipeline, and the personnel can carry out the installation construction of the gas pipeline;

[0027] After the construction of the gas pipeline is completed and the personnel need to disassemble it, the personnel can rotate the threaded rod 130 in the reverse direction to separate the locking block 131 from the side fixing slot 310. Then, the U-shaped chuck 300 can be pulled out upward. Then, the personnel can move the fixing seat 100 to both sides, so that the two fixing seats 100 are separated. The personnel can complete the disassembly of the fixing seat 100 and then splice and reuse it at the next place.
