Description

Technical Field

[0001] The utility model relates to the technical field of metal surface detection equipment, in particular to a non-magnetic wheel crawler. Background Art

[0002] Most crawlers used for detection and monitoring of metal surfaces use magnetic adsorption. Currently, the most common magnetic adsorption crawlers used for metal surfaces generally use magnetic wheels. Using magnetic wheels as adsorption components will make the structure simpler and easier to implement from a structural design perspective. However, magnetic wheels generally require customized designs. In order to obtain a relatively large magnetic adsorption force, the permanent magnets in the magnetic wheel must be specially designed and magnetized in different modules. At the same time, the assembly method must also use a special corresponding arrangement to achieve the required magnetic adsorption force. As a result, the cost of the magnetic wheel itself will be very high. For some use scenarios that are sensitive to cost requirements, the use of magnetic wheels is not very suitable. At the same time, the magnetic wheel itself is in direct contact with the surface to be detected, which sometimes has a certain impact on the detection structure of the adsorption surface.
