Description

Technical Field

[0001] The utility model belongs to the technical field of natural gas pipeline stabilization, and in particular relates to a natural gas long-distance pipeline installation stabilization device. Background Art

[0002] When long-distance pipelines are in use, for pipelines in stations and tunnels, the pipeline models are roughly differentiated into D1219×22mmL555M, D1016×22mm L555M, D610×22.2mm L415M, D610×20mm L415M, etc. In order to ensure the long-term safe operation of the transmission pipeline, it is necessary to install a pipe stabilizing device on the long-distance pipeline to maintain the pipeline settlement depth and stability.

[0003] After searching, the publication number: CN214618508U announced a natural gas long-distance pipeline installation stabilizing device. In the utility model, a plurality of bolts that abut against the natural gas pipeline are arranged on the counterweight block, so that the natural gas pipeline is supported and counterweighted by the counterweight block from multiple directions, and the length of the bolt passing through the counterweight block can be adjusted by screwing the bolt, so that the bolt abuts against the outer wall of the natural gas pipeline of different diameters, thereby meeting the requirements of the pipe stabilizing operation for the natural gas pipelines of different diameters.

[0004] However, as the ground anchor rods go deeper into the ground, the counterweights will squeeze the bottom surface of the long-distance pipeline, thereby increasing the pipeline load of the natural gas and reducing its service life. Moreover, this device is not conducive to the splicing of long-distance pipelines. During installation, multiple sets of counterweights need to be welded one by one, which is inconvenient to operate.

[0005] Therefore, a pipe stabilizing device for installing a long-distance natural gas pipeline is designed to solve the above problems. Utility Model Content

[0006] To solve the problems raised in the above background technology. The utility model provides a natural gas long-distance pipeline installation and stabilization device. When the device is in use, multiple groups of ground anchor rods can be inserted into the soft underground to enhance the stability of the arc base. Station straight seam steel pipes of different sizes can be placed inside the arc base, and then covered with an aluminum alloy top cover, which is screwed into the threaded holes on the inner side of the connecting plate with bolts to achieve the docking of the arc base and the aluminum alloy top cover. In this process, this aluminum alloy material is a metal plate with a long service life, light weight, and a certain noise reduction function; on the other hand, the bottom semicircular array of the arc base has several groups of buffer pads, which can alleviate the friction between the arc base and the ground contact surface, thereby enhancing the service life of the arc base. During the installation process, only a single group of plug-in steel plates need to be horizontally inserted into the slots of the arc base and the aluminum alloy top cover to complete the splicing, which is easy to operate.

[0007] To ensure stable clamping of steel pipes of different sizes, the staff can manually turn the top rotating handle of the positioning frame, and its bottom drives the threaded rod to rotate. With the rotation coordination of the threaded rod and the bottom movable block, the movable block can be stably moved downward in the parallel direction of the limit rod, ensuring that the bottom push rod can push the block against the outer wall of the steel pipe, thereby improving the stability of the pipeline; and when the pipeline shakes, the push rod is pushed along the inner rod end of the piston rod, so that the piston rod drives the limit spring to compress, and then the limit spring quickly recovers, and the inner rod of the piston rod quickly recovers and maintains the tightening effect on the pipeline, thereby stabilizing the clamped pipeline and improving the stability performance.
