Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing devices, in particular to a pipeline welding tool for complex environments. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by a blower, compressor, pump and boiler. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Among them, pipelines are classified according to the conveying medium: water supply and drainage pipelines, compressed air pipelines, hydrogen pipelines, oxygen pipelines, acetylene pipelines, thermal pipelines, gas pipelines, fuel pipelines, highly toxic fluid pipelines, toxic fluid pipelines, acid and alkali pipelines, boiler pipelines, refrigeration pipelines, purified pure gas pipelines, and pure water pipelines.

[0003] During the pipeline construction process, the pipeline needs to be welded. The existing welding methods mostly use welding from the external interface, which leads to cracks on the inner wall of the pipe end joint, low sealing, and unreliable welding. Especially in large pipelines, the welding quality must be guaranteed. Therefore, it is necessary to smooth the internal joints of the pipeline. At present, the fixing stability between the welding of the pipeline is poor, which makes the welding operation inconvenient and difficult to ensure the welding quality and welding efficiency. For this reason, we propose pipeline welding tooling for complex environments. Summary of the invention

Therefore, it is very necessary to smooth the internal joints of the pipeline, and the current fixation stability between pipeline welding is poor, which makes welding operations inconvenient and difficult to ensure welding quality and welding efficiency.

[0012] Compared with the prior art, the present invention provides a pipeline welding tool for complex environments, which has the following beneficial effects:

[0013] 1. The pipeline welding tooling for complex environments drives the rotating column to rotate through the first hydraulic cylinder through the second fixing piece, and then supports the support wheel in the middle of the connection gap between the inner walls of the two pipes, and then drives the protective pad to support the inner wall of the pipe through the second hydraulic cylinder, and then adjusts the position so that the output shaft of the driving motor can be inserted into the fixed cylinder, and then fixed with the second clamping screw, and then drives the fixed disc to rotate with the driving motor, and then the fixed disc drives the support wheel to roll and support in the middle of the connection gap between the inner walls of the two pipes, which can support the inner wall during welding to reduce the crack points of the two pipes, ensure the firm strength of the connection between the two pipes, and also ensure the sealing of the connection between the two pipes, thereby improving the quality of pipeline welding.
