Wheeled inspection robot

Abstract

The invention discloses a wheel type detection robot. The wheel type detection robot comprises a body and a driving device; the body is provided with a rotating shaft, and the driving device is in driven connection with the rotating shaft; and the rotating shaft is provided with a magnetic wheel which comprises a wheel shell and a magnetic body arranged in the wheel shell, the wheel shell is fixedly connected to the rotating shaft, and the magnetic body is rotationally connected to the rotating shaft in a sleeving manner. When the wheel type detection robot runs, the driving device drives the rotating shaft to rotate, the wheel shell fixed to the rotation shaft rotates along with rotation of the rotating shaft, and therefore movement of the body is achieved. In the body movement process, the magnetic body rotationally connected to the rotating shaft provides magnetic force, it is guaranteed that the wheel shell can be attracted to the inner wall or the outer wall of a pipe to walk, and the requirement for running on a straight pipe, a tapered pipe and a bend pipe can be met. The wheel type detection robot is simple in structure and good in flexibility, stability and adaptability, and has the good popularization significance.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wheeled detection robot. Background technique [0002] At present, industrial piping systems have been widely used in metallurgy, petroleum, chemical industry and urban plumbing supply and other fields. The environment inside the pipeline is very harsh. Corrosion and fatigue damage will occur after long-term use, and it is easy to develop into damage and cause leakage accidents. Once toxic, harmful, flammable and explosive materials are discharged into the atmosphere out of control, it will seriously affect people's normal production and living order. Therefore, the pipeline must be inspected and maintained regularly. However, because the location of the pipeline is often difficult for people to reach, it is very difficult to overhaul. Generally adopted methods such as early scrapping, excavation and maintenance are not ideal, not only labor-intensive, low-efficiency, but als...

AI Technical Summary

Problems solved by technology

At present, there have been some achievements in the research on pipeline inspection robots, but most pipeline inspection robots can only run on straight pipes, and cannot be used on variable diameter pipes and curved pipes that are widely used in engineering.

However, a small number of pipeline inspection robots that can run on variable diameter pipelines and curved pipelines mainly rely on supporting the inner wall of the pipeline to walk, and cannot walk along the outer wall of the pipeline.

This way of walking is poor in flexibility, stability and adaptability, and its application is extremely limited
