Abstract

The invention discloses a pressure pipeline welding seam grinding device. The pressure pipeline welding seam grinding device comprises centering positioning mechanisms, a spiral feeding mechanism and a grinding head, wherein the spiral feeding mechanism comprises a rail piece, a driving piece and a moving piece, the rail piece and the driving piece are coaxially arranged, the moving piece is provided with an outer moving end and an inner moving end, and the outer moving end is matched with a spiral rail and moves along the spiral rail; the two ends of the spiral feeding mechanism are connected with the two centering positioning mechanisms respectively, each centering positioning mechanism is provided with a positioning end, the centering positioning mechanisms are used for fixing the spiral feeding mechanism to the outer side of a pipeline, and one end of the corresponding spiral feeding mechanism is concentric with the pipeline; and the grinding head is connected to the inner moving end and is used for grinding the outer side of the pipeline. According to the pressure pipeline welding seam grinding device, the driving piece drives the moving piece to move along the spiral rail, after the grinding head is started, the grinding head continuously rubs with the outer side wall of the pipeline for grinding, manual grinding is effectively replaced, the efficiency is high, and the grinding effect is uniform.

Description

technical field [0001] The invention relates to the technical field of special equipment detection, in particular to a welding seam grinding device for pressure pipelines. Background technique [0002] Pressure pipeline refers to all pipelines subject to internal or external pressure, regardless of the medium in the pipe, pressure pipeline is a kind of pipeline, and the pipeline is used to transport, distribute, mix, separate, discharge, measure, control and stop fluid flow An assembly consisting of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure parts and supports. [0003] In-use pressure pipes need to be inspected regularly, and before the inspection, it is necessary to derust, remove paint and polish the weld seam and a certain range on both sides to expose the metallic luster. Generally, it is manually polished, and it is often difficult to polish the side of the pipeline away from people, and the efficiency of manual polishi...
