Smooth cutting equipment for petroleum pipeline

Abstract

The invention discloses smooth cutting equipment for a petroleum pipeline. The smooth cutting equipment is characterized by structurally comprising an upper blocking base and a lower blocking base, wherein the upper blocking base and the lower blocking base are consistent in structure, and are in locking connection; and the upper blocking base consists of a power supply joint, a handle, arc-shapedslide rails, a rotary device, a cutting device, a ring-shaped path and arc-shaped gear rings. The smooth cutting equipment has the beneficial effects that: the smooth cutting equipment is provided with the upper blocking base and the lower blocking base, first electromagnets are arranged at the inner sides of the two blocking bases, and the first electromagnets generate magnetism while energizedto firmly absorb a pipeline; a convex shaft on the upper blocking base is matched with a groove in the lower blocking base, a second electromagnet and a third electromagnet are energized to generate magnetism with reverse polarity to attract each other while the power supply joint is energized, so that the upper blocking base and the lower blocking base are firmly locked on a pipeline, and therefore, a shaking phenomenon during cutting is prevented; and arc-shaped slide rails and arc-shaped gear rings are arranged on the two blocking bases, so that dual-rail operation is achieved, and a rotator can stably operate, and therefore, a pipeline surface slanting phenomenon is avoided, and flatness of the end surface of the pipeline is guaranteed.

Description

technical field [0001] The invention relates to a smoothing and cutting equipment for petroleum pipelines, and belongs to the technical field of smoothing and cutting equipment for pipelines. Background technique [0002] my country's oil pipeline construction will usher in a new climax. At present, oil pipelines have become one of the main transportation tools for oil, and they still have considerable development potential in the future. The pipes of oil pipelines are generally steel pipes, which are connected by welding and flanges. The device connects long-distance pipelines. During the connection process, it is necessary to cut the specifications of the pipelines and cut them into sizes that meet the needs of the site. During the cutting process, the ports often appear uneven. When the end faces of the two pipelines are connected, There will be gaps, and it needs to be re-polished, which is troublesome to operate.
