The invention provides an automatic
crawling grinding robot for the inner wall of a circular
pipe, and belongs to the technical field of descaling of relief pipelines. The automatic
crawling grindingrobot comprises a shell, a main driving module, a driving base,
grinding modules and a
crawling module, the shell comprises a left shell body and a right shell body, and the driving base comprises a first driving base body and a second driving base body; the main driving module, the crawling module and a plurality of supporting wheels are installed on the outer end face of the driving base, the multiple
grinding modules are evenly distributed between the outer end face of the right shell body and the opposite end faces of the second driving base body in the circumferential direction, and the crawling module drives a grinding device to do
linear motion along the outer wall of the to-be-ground pipeline; and the main driving module drives the shell to drive the grinding modules to rotate in the circumferential direction of the inner wall of the pipeline through
gear transmission. The device is wide in application range, dismounting, mounting and grinding work of the grinding
machine can be completed through one-man operation, a detection device is arranged on the outer end face of the driving base, detection of the
pipe wall thickness, cracks and the
corrosion condition is achieved while the pipeline is ground, and one
machine has multiple purposes.
