For the routine maintenance and fault repair of the horizontal section GIL pipeline busbar, at present, the maintenance of the flange-type GIL mother pipe in China mainly uses fast-installation scaffolding to hard isolate the mother pipe and uses temporary lifting points to disassemble and assemble the mother pipe. There is no special tooling for disassembly and maintenance of the flange-type mother pipe, which makes it impossible to complete the maintenance work safely and efficiently, and it is impossible to complete the maintenance of the GIL horizontal section mother pipe safely and efficiently. Summary of the invention

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a scissors-type GIL pipe lifting device, including a base, on which is provided a scissors-type lifting mechanism and a hydraulic cylinder for driving the scissors-type lifting mechanism to extend and retract, a lifting platform is provided on the top of the scissors-type lifting mechanism, an extension platform is slidably connected to the lifting platform, and also includes a push rod for driving the extension platform to move, and a GIL pipe fixing seat is provided at the front end of the extension platform.

[0005] Preferably, the GIL pipe fixing seat is a hollow V-shaped structure, a plurality of rollers are provided on the inner side of the GIL pipe fixing seat, and a through hole is provided on the side wall of the GIL pipe fixing seat, and the through hole is used for a binding belt to pass through to fix the GIL pipe.

[0006] Preferably, a pulley and a steering wheel are provided at the bottom of the base.

[0007] Preferably, telescopic rods extending from both sides are provided at the four corners of the base, and adjustable feet are threadedly connected to the ends of the telescopic rods.

[0008] Preferably, a front extension rod is provided on the front side of the base, and an adjusting foot is threadedly connected to the end of the front extension rod.

[0009] The utility model provides a scissor-type GIL pipeline lifting device, which uses a scissor-type lifting device to drive the GIL pipeline to lift and lower, thereby completing the disassembly and assembly of the GIL pipeline. It has the characteristics of stability, reliability, flexibility and efficiency, and can greatly improve the safety of the operation, protect adjacent electrical equipment, improve maintenance efficiency, and shorten the maintenance period. At the same time, the device can move in both the axial direction and the horizontal radial direction of the pipeline, which improves the accuracy during disassembly and assembly; in addition, the device uses a scissor-type lifting device, and after the scissor mechanism is retracted, the device is small in size and low in height, which is convenient for moving in a smaller indoor environment.
