Grinding device for inner wall of pipeline

Abstract

The invention relates to a grinding device for the inner wall of a pipeline and belongs to the technical field of grinding operation devices for the inner walls of pipelines. The grinding device comprises a machine body and a grinding tool. A main motor and a traveling motor are arranged on the machine body, and the main motor is in driving connection with the grinding tool; the traveling motor isin driving connection with a sliding rod through a transmission mechanism; a shaft sleeve or a guide rail matched with the sliding rod is arranged on the machine body; the transmission mechanism enables the sliding rod to make reciprocating movement in the horizontal direction; the end, away from the transmission mechanism, of the sliding rod is fixedly connected with a driving rack; the drivingrack is connected with driving wheels through first connecting rods, and the driving wheels are arranged in the circumferential direction of the machine body; the machine body is connected with traveling wheels through second connecting rods, and the traveling wheels are arranged in the circumferential direction of the machine body; and the driving wheels and the traveling wheels are both unidirectional rotating wheels and travel in the same direction. An extra traveling traction device and other machine auxiliary devices are not needed, the structure is simple, the manufacturing cost is low,and the working efficiency is high.

Description

technical field [0001] The invention relates to a pipeline inner wall grinding device, which belongs to the technical field of pipeline inner wall grinding operation devices, and can be applied in the fields of metal pipelines such as hydropower station water delivery and industrial water delivery. Background technique [0002] Metal pipes are widely used in industrial engineering and daily life. For example, in a hydropower station, the pipeline is used to transport liquid, and due to the humid air, the metal pipeline without anti-corrosion treatment is prone to corrosion and rust problems during long-term use, so that the transported liquid is mixed with various impurities, which affects the machinery. The running accuracy of the machine will be serious, and it will cause mechanical failure in severe cases. Therefore, it is extremely important to paint the inner wall of the metal pipeline for anti-corrosion treatment and rust removal. However, due to the special working s...
