Abstract

The utility model relates to the technical field of pipeline disassembly, and discloses a fixing structure and an auxiliary device for pipeline disassembly. The moving unit comprises an adjusting assembly, a first limiting assembly arranged on one side of the adjusting assembly, a second limiting assembly installed on one side of the adjusting assembly and a limiting ball arranged in the adjusting assembly. The pipeline lifting device has the advantages that through cooperation of the first limiting assembly, the second limiting assembly and the limiting ball, the adjusting assembly can move and be fixed on the cross beam, the adjusting assembly can adapt to different space sizes, meanwhile, shaking in the pipeline lifting process can be reduced when the adjusting assembly is fixed to a proper position, and the pipeline lifting efficiency is improved. Damage caused by collision of the pipeline is effectively reduced; the device can be fixed to a pipeline flange to be disassembled through the connecting bases, different connecting bases can be replaced through connection of the auxiliary beams and the cross beams, pipelines of different sizes can be disassembled, and the application range of the device is widened.
