Abstract

The invention belongs to the technical field of special industrial robots, and relates to a TOFD flaw detection wall-climbing robot, which includes electrical components, crawling components and flaw detection components. , the flaw detection component can move linearly along the plate surface parallel to the mounting plate; the crawling component includes an adsorption body and a crawling wheel that can be adsorbed on the crawling surface, and the crawling wheel protrudes from the adsorption surface of the adsorption body; the invention can realize the TOFD flaw detection robot along the Crawling detection of welding defects on curved surfaces such as spherical tanks and pipe walls, and the robot has a strong ability to overcome obstacles. The positioning of the robot during the detection process is stable and reliable, which improves the detection accuracy, reduces the danger caused by manual detection, and improves the environmental adaptability of the detection robot. Expand the detection range and realize intelligent high-standard detection work.

Description

technical field [0001] The invention belongs to the technical field of special industrial robots, in particular to a TOFD flaw detection wall-climbing robot. Background technique [0002] With the development of science and technology, it has gradually become the mainstream trend for robots to replace humans to complete simple, repetitive, high-risk, and high-intensity labor. Gap-type permanent magnetic adsorption wall-climbing robot is a special robot widely used in nuclear industry, petrochemical, shipbuilding and other dangerous industries. Time Of Flight Diffraction (TOFD) is a method to detect defects by relying on the diffraction energy obtained from the "end angle" and "end point" of the internal structure of the test piece (mainly refers to defects). Mainly used for defect detection, quantification and localization. With the improvement of operation requirements and the gradual increase of operation risk, especially in the petrochemical industry, in the manufacturi...
