Description

Technical field

[0001] The invention relates to a wall-climbing robot used for magnetic particle inspection. Background technique

[0002] Large high-altitude equipment, such as pressure vessels, port logistics equipment, etc., require regular safety inspections. Magnetic particle inspection is the most commonly used non-destructive inspection method. At present, non-destructive testing is mainly done manually, and there are problems such as cumbersome work, low efficiency, and high risk.

[0003] The wall-climbing robot is a mobile automation device that can be adsorbed on the surface of the tank. It can replace workers in dangerous and extreme environments such as nuclear engineering, fire protection, and the manufacturing and maintenance of large non-structural equipment. Summary of the invention

[0004] In order to solve the problems of cumbersome, low-efficiency, high-risk and other problems of manual magnetic inspection of equipment in the prior art, a wall-climbing robot fo...
