Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: during the welding process of the pipeline, one end of a welded long pipeline will be involved in connecting a pipeline with a smaller diameter through a tapered section. The larger end comes out, and its walking distance is too long. Since the inner welding machine has only one walking part, and the side of the walking part away from the rotating guide frame is parallel to the axis of the rotating guide frame, it cannot walk on the tapered section, making the inner welding machine After the welder has welded the tapered section and the smaller diameter pipe to the larger diameter pipe, the inner welder is more difficult to remove

The invention relates to a steel gas pipeline fully-automatic inner welding machine, and belongs to the technical field of inner welding machines. The steel gas pipeline fully-automatic inner weldingmachine comprises a machine body, the machine body is provided with a traveling mechanism, a rotary welding mechanism is arranged at one end of the machine body, the rotary welding mechanism comprisesa rotating frame and a welding gun, the rotating frame is rotatably connected with a barrel shaft of the machine body, the welding gun is arranged in the radial direction of the rotating frame, and avariable diameter traveling assembly is arranged at the end, away from the machine body, of the rotating frame. The steel gas pipeline fully-automatic inner welding machine has the effect of being capable of moving between pipelines with different pipe diameters.
Description
technical field [0001] The invention relates to the technical field of internal welding machines, in particular to a fully automatic internal welding machine for steel gas pipelines. Background technique [0002] At present, the internal welding machine is also called the automatic welding machine for the inner circular seam of the pipeline. It is mainly used in the construction of petrochemical, electric power, coal, water transmission and other pipelines. The main function is to complete the assembly of two pipelines and internal root welding. [0003] The existing Chinese patent whose notification number is CN107552921B can be referred to, which discloses a pipeline internal welding machine, the welding device is connected with the walking device; the welding device includes: a rotating guide frame and the end face of the first transmission part of the running device The bearing is connected; the straight-running part is connected with one end of the rotating guide frame;...
