Abstract

The invention discloses a pressure pipe welding seam grinding device, which includes a centering positioning mechanism, a screw feeding mechanism and a grinding head, wherein: the screw feeding mechanism includes a track piece, a driving piece and a moving piece, and the track piece and the driving piece are the same The shaft is set, the moving part has an outer moving end and an inner moving end, and the outer moving end cooperates with the spiral track and moves along the spiral track; the two ends of the screw feeding mechanism are respectively connected to two centering positioning mechanisms, and the centering positioning mechanism has a positioning end. The screw feeding mechanism is fixed on the outside of the pipeline, and one end of the corresponding screw feeding mechanism is arranged concentrically with the pipeline; the grinding head is connected to the inner moving end for grinding the outside of the pipeline. The driving part of the invention drives the moving part to move along the spiral track. After the grinding head is turned on, the grinding head continuously rubs against the outer wall of the pipeline for grinding, which effectively replaces manual grinding, and has high efficiency and uniform grinding effect.

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...
