De-rusting and spraying intelligent robot in pipeline

Abstract

The invention discloses a de-rusting and spraying intelligent robot in a pipeline. The robot comprises a control case, a driving mechanism, a de-rusting mechanism, a spraying mechanism and a cable. The control case is connected to the driving mechanism, the de-rusting mechanism and the spraying mechanism through the cable. The driving mechanism, the de-rusting mechanism and the spraying mechanism are integrally connected, wherein the driving mechanism is arranged at the front position, the de-rusting mechanism is arranged between the driving mechanism and the spraying mechanism, and the spraying mechanism is arranged at the tail position. According to the invention, the de-rusting and spraying intelligent robot in the pipeline can accurately capture weld joints through a micro-current tactile sensing weld joint capture positioning wheel, good weld grinding effects can be achieved, a coating layer is uniform in thickness, and sagging defects are not caused. The robot is simple in structure, light in weight and small in size, and is convenient to manufacture.

Description

technical field [0001] The invention relates to the technical field of rust removal and anticorrosion repairing in pipelines at home and abroad, in particular to an intelligent robot for rust removal and spraying in pipelines. Background technique [0002] The pipeline anticorrosion repairing process is an important part of ensuring the structural integrity of long-distance pipelines. Like a gorgeous garment, it must be shaped by sewing a strong joint. At present, steel pipes are mainly used to transport oil, gas, water and other media, and the anti-corrosion coating at the joints of steel pipes is completed at the construction site. Due to the large difference between the on-site anti-corrosion jointing operation environment and the anti-corrosion production factory environment, on-site jointing has become a weak link in pipeline anti-corrosion. Every year in my country, huge economic losses are caused by corrosion and perforation of pipelines, and even various accidents o...
