Installation device for blast furnace gas pipeline

The invention belongs to the technical field of blast furnace pipeline installation, and particularly provides a blast furnace gas pipeline installation device which comprises a hoisting assembly and a welding assembly, the hoisting assembly is used for hoisting a blast furnace gas pipeline to a pipeline support, the welding assembly comprises a fixing ring, a supporting frame, an adjusting mechanism and a welding mechanism, and the fixing ring is arranged on the periphery of the gas pipeline in a sleeving mode; the supporting frame can conduct circular motion around the pipeline welding seam along the first track, during the moving period of the supporting frame, the welding mechanism can conduct circular welding on the whole pipeline welding seam, and the hoisting assembly and the welding assembly act jointly so that the two gas pipelines can be welded into a whole. By arranging the fixing ring, the supporting frame and the adjusting frame, the welding mechanism can conduct welding operation on a pipeline w
