Description

Technical Field

[0001] The utility model relates to the field of pipeline welding, in particular to a pipeline welding and grinding device. Background Art

[0002] Anti-corrosion pipes refer to pipes that can slow down corrosion and extend their service life. Anti-corrosion pipes will be sprayed with anti-corrosion paint. When welding the pipes, the welds of the pipes need to be polished to make their surface smooth and flat to facilitate the spraying of anti-corrosion paint.

[0003] In the current existing technology, after the pipeline is welded, the staff needs to grind the weld to make the weld smooth and flat. The corresponding grinding device needs to be used for grinding. The grinding device is mainly composed of a shell, a motor and a grinding wheel. The motor drives the grinding wheel to rotate at high speed. The high-speed rotating grinding wheel grinds the weld, thereby removing the raised weld and making the connection of the pipeline smooth and flat, so as to facilitate subsequent anti-corrosion treatment.

[0004] However, during grinding, the pipeline weld is circled, and the pipeline needs to be turned over for grinding, but the metal pipeline is relatively heavy and inconvenient to turn over; therefore, a pipeline welding grinding device is proposed to address the above problem.
