Description

technical field

[0001] The invention relates to the technical field of installation of GIL through-pipes, in particular to a tooling trolley used for hoisting GIL through-pipes. Background technique

[0002] Compared with conventional power transmission equipment such as insulated bus bars, GIL (Gas Insulated Metal Enclosed Transmission Line) has the advantages of simpler structure, larger transmission capacity, high safety, strong flow capacity, and low processing requirements. However, the GIL pipe path is long, and the machining accuracy and assembly deviation easily affect the reliable operation of the product. At the same time, the on-site installation environment and assembly process requirements are extremely high, which requires GIL to have reliable transportation and installation equipment for on-site installation.

[0003] In the limited installation space, the precise transportation and installation of several tons of GIL equipment has extremely high requirements...
