Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of grinding natural gas pipeline cuts in the prior art, which is time-consuming and labor-intensive, and the grinding efficiency is low, and it is often difficult to grind evenly, requiring repeated grinding. New burrs will be generated, and it is difficult to remove them synchronously, so a kind of grinding equipment for the truncation of natural gas pipelines is proposed

Abstract

The invention belongs to the technical field of pipeline polishing, and particularly relates to natural gas pipeline cut-off notch polishing equipment. The polishing equipment comprises a base, a first shell and a second shell, the first shell and the second shell are both fixedly arranged at the top of the base, openings are formed in the right side of the first shell and the left side of the second shell, a plurality of U-shaped connecting rods are jointly connected to the first shell and the second shell, a feeding port is formed in the left side of the first shell, two first sliding rods are fixedly arranged in the first shell and are sleeved with first sliding blocks in a sliding mode, first connecting rods are fixedly connected to the two first sliding blocks, and a lower arc-shapedblock is fixedly connected to the ends, close to each other, of the two first connecting rods. According to the polishing equipment, natural gas pipelines with different calibers can be conveniently positioned, fixed and polished, iin addition, new burrs generated by polishing can be effectively removed through polishing rods, notches can be polished to be smooth through a polishing sheet of whichrevolution and autorotation are synchronously carried out, time and labor are saved, and the polishing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline grinding, and in particular relates to a grinding equipment for a truncation opening of a natural gas pipeline. Background technique [0002] The transportation of natural gas requires natural gas pipelines. During the transportation process, natural gas pipelines need to be extremely tight to prevent natural gas leakage. Therefore, when connecting natural gas pipelines, flat cuts are required to ensure that natural gas will not leak. However, the general cutting method is hacksaw or mechanical The cutting method is used to cut. After cutting, impurities such as heavy skin, bumps, shrinkage, slag, oxides, and iron filings will appear in the pipe cut, which will affect the connection between the pipes. Therefore, the natural gas pipe cut needs to be polished. [0003] The current natural gas pipeline cut grinding mainly uses workers to grind the natural gas pipeline with a hand-held grinder, which...
