Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, in particular to a portable maintenance device for natural gas pipelines. Background Art

[0002] Natural gas pipelines are trunk pipelines that transport natural gas to users. They start from gas fields, oil fields or LNG receiving stations, and often end at urban gas distribution stations. Natural gas is mainly composed of methane, with a content of more than 80%, and contains ethane, propane, butane and its isomers and other heavier gaseous hydrocarbons. It also often contains hydrogen, nitrogen, hydrogen sulfide, carbon dioxide and a small amount of inert gases such as helium and argon. Before the gas enters the gas pipeline, it must be purified to meet the quality requirements of commercial natural gas.

[0003] A Chinese patent application CN208778989U discloses a portable maintenance device for natural gas pipelines. The key points of its technical solution are: its two-stage support body design can arbitrarily change the length of the support and is applied to different environments. It uses a nut to control the adjustment of the screw rod and is equipped with a nut fixing device, which can effectively control the length of the screw rod and is convenient for workers to use. The device as a whole adopts a purely manual mechanical structure, which ensures that the device will not generate sparks during use and ensures safety of use. When not in use, the device can be disassembled into multiple sections for separate carrying, which is simple and portable. The utility model has the advantages of simple structure, reasonable arrangement, and low production cost.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when repairing a natural gas pipeline, the natural gas pipeline needs to be disassembled frequently.
