An industrial spraying robot for pipe spraying

Abstract

The invention discloses an industrial spraying robot used for pipeline spraying. The industrial spraying robot used for pipeline spraying comprises a pipeline, a spraying mechanism and a traction mechanism, wherein the spraying mechanism comprises a four-claw type supporting frame, the included angle between every two adjacent claw bodies is 90 degrees, a base is fixed at the tail end of each clawbody, an idler wheel is arranged in each base, each idler wheel is connected with a driving shaft through a transmission system, and each driving shaft is fixedly provided with a driving gear; a transverse pipe is rotationally fixed on one side of the supporting frame, a pipe body of the transverse pipe is provided with a driven gear ring, spraying heads and a limit ring, a hopper is fixedly arranged on the supporting frame, the hopper communicates with the transverse pipe through a feed pipe, and a pump body providing spraying pressure is arranged in the hopper; and the traction mechanism iscomposed of a rope reeling block, a telescopic support, a driving motor and a walking device, and a reeled rope is connected between the rope reeling block and the supporting frame. The spraying mechanism moves along the inner wall of the pipeline under the action of the traction mechanism, the transmission mechanism are utilized to drive the spraying heads to rotate to realize uniform spraying in the moving process of the idler wheels, the cost is low, and use and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to an industrial spraying robot used for pipeline spraying. Background technique [0002] Pipeline engineering plays a very important role in the core industries of the national economy such as oil, natural gas, nuclear industry, water supply and drainage, and pipeline transportation. For buried pipelines operating outdoors, after nearly 30 years of operation, the protective layers of the inner and outer walls of the pipeline have aged or even severely corroded. In order to ensure the normal transportation of pipelines, technicians are required to repair the inner and outer walls of pipelines—spraying anti-corrosion coatings. The traditional spraying equipment consists of a host, a feeding pipe, and a hand-held spray gun. It is not suitable for spraying the inner wall of a narrow and long pipeline, and the traditional spraying equipment needs to be improved. [0003] For...
