A convenient buried pipeline lifting device

Abstract

The invention relates to the field of pipeline lifting, in particular to a conveniently buried pipeline lifting device, including a sleeve, a shell, a lifting structure, an adjusting structure, an auxiliary structure and a protective structure; the adjusting structure is made to work by pressing down on the adjusting structure The power drives the lifting structure to work, so that the lifting structure moves up to push the pipeline to lift, so that one of the pipelines is lifted to the same height as one end of the other pipeline, so as to facilitate the fixed connection between the two pipelines for laying and embedding of pipelines, and adjust the working process of the structure During the process, the gas is blown to the lifting structure to dissipate heat from the lifting structure, which is beneficial to the lifting structure for pipeline lifting. After the lifting structure moves up, the protective structure is intermittently pushed to work, so that the protective structure intermittently injects lubricating oil into the surface of the lifting structure, which is beneficial to the lifting structure. Carry out lubrication protection, save lubricating oil at the same time, and prevent excessive waste of lubricating oil during lubrication.

Description

technical field [0001] The invention relates to the field of pipeline lifting, in particular to a conveniently buried pipeline lifting device. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. The pipeline is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various in industrial installations. [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 ...

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
