Description
Technical Field
The utility model relates to the technical field of submarine pipeline laying in ocean engineering, in particular to a travelling rail of a magnetic cutting machine for a submarine pipeline with a three-layer polyethylene coating.
Background
At present, in the development process of offshore oil and gas, oil or gas transportation needs to be completed by laying submarine pipelines, and the submarine pipelines comprise three layers of polyethylene, cement coating weights and three layers of polyethylene single-layer and double-layer pipelines according to different transportation media (oil, gas or oil gas).
The pipe lifting and discarding operation is frequently carried out in the submarine pipeline laying process, and the cutting and expansion bending prefabrication blanking welding operation of the double-layer pipe wrapping plate is carried out. The pipeline magnetic cutting machine is required to be used at this time, the pipeline cutting machine is provided with two groups of four permanent magnetic wheels, the pipeline cutting machine automatically surrounds the steel pipe through a transmission mechanism to cut, and the cutting process can adopt fast oxygen flame or propane oxygen flame. It is suitable for cutting and beveling seamless steel pipe of different specifications above 108 mm. Because of the adsorption force of the magnetic wheel, the cutting machine can also carry out all-position multidirectional cutting on various spatial positions of flat, vertical, horizontal and upward, and the cutting and the beveling can be completed once.
When three-layer polyethylene pipeline cutting operation is laid, the magnetic wheels at the back of the magnetic force cutting machine cannot be directly adsorbed on the exposed outer wall of the steel pipe, but are directly arranged on the three-layer polyethylene rubber protection layer of the pipeline, and the magnetic force cutting machine and the sea pipe have insufficient adsorption force due to the insulation effect of the rubber protection layer on the magnetic wheels. Therefore, the magnetic force cutting machine loses the capability of running along the circumference of the outer wall of the pipeline to perform cutting processing. Therefore, a chloroprene rubber protective layer which is attached to the submarine pipeline and is in a certain length close to the end of the exposed steel pipe needs to be melted and removed cleanly by a baking gun manually, so that the magnetic force cutter is ensured to adsorb and climb on the outer wall of the submarine pipeline. Therefore, the existing cutting method is complicated, and the labor intensity of operators is high; the processing efficiency is low, and the safety is poor; furthermore, the rubber on the metal surface is polished by a grinder, so that scattered dust and waste gas are easy to cause atmospheric pollution, and the environment protection is not facilitated.
