Round tube outer wall crawling robot

Abstract

The invention discloses a round tube outer wall crawling robot which includes a front tightly holding device and a rear tightly holding devices which are arranged side by side. The rear tightly holding device and the front tightly holding device are jointly hinged to a crawling device. The crawling device includes a servo motor fixed on the rear tightly holding device, the servo motor is connectedwith a screw, a nut is embedded in the position, corresponding to the screw, of the front tightly holding device, and the screw extends into the nut. The round tube outer wall crawling robot can crawl along an outer wall of a round tube with a smaller diameter and turn.

Description

technical field [0001] The invention belongs to the technical field of robots and relates to a crawling robot on the outer wall of a circular pipe. Background technique [0002] In ships, metallurgy, construction, chemical industry, beverage and other equipment, there are various pipelines. The fluid passing through these pipelines may be compressed air, chemical gas, high-pressure steam, certain liquids, etc. After long-term use Damage phenomena such as corrosion and cracks may occur inside and outside the pipeline, resulting in safety accidents, so regular inspection and maintenance are required. Because these pipelines are often densely arranged, have various diameters, and some are high in height, sometimes manual maintenance is difficult and difficult to carry out frequently. With the development of robots and detection technology, pipeline maintenance robots have emerged as the times require, making pipeline maintenance a easy thing. Some of these robots simply inspe...

AI Technical Summary

Problems solved by technology

For pipelines with larger diameters, the robot can crawl a greater distance and perform maintenance in the pipelines, while for pipelines with smaller diameters and many turns, the crawling in the pipelines of the robot is limited by towing cables, etc., making it difficult to crawl for a long distance and easy to get stuck. Therefore, it is difficult to complete the maintenance while crawling inside the pipe. It may be considered to crawl outside the pipe and carry out proper detection. Currently, no one has developed a crawling robot on the outer wall of the pipe.
