Conveniently buried pipeline lifting device

Abstract

The invention relates to the field of pipeline lifting, in particular to a conveniently buried pipeline lifting device, which comprises a sleeve, a shell, a lifting structure, an adjusting structure,an auxiliary structure and a protection structure, wherein the adjusting structure is pressed, so that the power for work of the adjusting structure drives the lifting structure to work, the lifting structure moves up to push a pipe to lift, and one pipeline is lifted to the same height of one end of the other pipeline to benefit fixed connection between the two pipelines for pipeline laying and burying; the adjusting structure blows gas to the lifting structure in a working process in order to cool the lifting structure, so that the lifting structure works to preform pipeline lifting; after the lifting structure works and moves up, the protection structure is intermittently pushed to work, so that the protection structure intermittently injects lubricating oil into the surface of the lifting structure, the lubricating protection is performed on the lifting structure, meanwhile, the lubricating oil is saved, and the excessive waste in a lubricating process of the lubricating oil is prevented.

Description

Technical field [0001] The invention relates to the field of pipeline lifting, in particular to a pipeline lifting device that is convenient to bury. Background technique [0002] Pipes are devices that are connected by pipes, pipe couplings and valves to transport gases, liquids or fluids with solid particles. Generally, the fluid is pressurized by blowers, compressors, pumps, and boilers, and then the high pressure It can also be transported by the pressure or gravity of the fluid itself. The pipeline has a wide range of uses, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various Industrial installations. [0003] However, during the erection of the gas pipeline, when the two pipelines are connected between two pipelines, the connecting ends of the two pipelines are at different heights. Due to the heavy weight of the pipeline, it is difficult to raise the two pi...

Problems solved by technology

[0003] However, during the erection of gas pipelines, when the two pipelines are connected between two pipelines, the connecting ends of the two pipelines are at different heights. Due to the heavy weight of the pipelines, it is difficult to lift the two pipelines to connect at the same height, which will affect the pipeline. laying efficiency, the traditional pipeline lifting equipment has a large volume, which is not conducive to the lifting and connection of pipelines in a small space
