Description

Technical Field

[0001] The utility model belongs to the technical field of docking devices, and in particular relates to a gas pipeline docking device. Background Art

[0002] Gas pipeline refers to a special pipeline system used to transport natural gas, liquefied petroleum gas and other gas media, and is an important part of the city's gas supply infrastructure. During the installation process of gas pipelines, it is often necessary to connect and assemble different sections of pipelines to make them interconnected and integrated. However, most pipelines are large in size and heavy, so the traditional installation method cannot be effectively connected manually, which may make the docking parts unable to be tightly connected, and deviations may cause the existence of some tiny gaps, which may cause gas leakage in later use.

[0003] Secondly, the manual method of connecting the gas pipeline requires a large number of people to work at the same time, which consumes a lot of manpower and labor costs, and increases the labor intensity of the installation and connection personnel. In addition, there is a problem that the pipeline may fall and injure the installer during the installation and connection process.

[0004] In summary, there are some problems with the traditional manual method for connecting gas pipelines, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
