Abstract

The invention belongs to the technical field of special industrial robots, and particularly relates to a TOFD flaw-detection wall-climbing robot. The TOFD flaw-detection wall-climbing robot comprisesan electrical part, a climbing part and a flaw detection part, wherein the electrical part is arranged at one side of a mounting plate, the climbing part and the flaw detection part are arranged at the other side of the mounting plate, and the flaw detection part can linearly move along a board parallel to the mounting plate; the climbing part comprises an attraction body and climbing wheels, wherein the attraction body and the climbing wheels can be attracted onto a climbing face, and the climbing wheels protrude out of the attraction face of the attraction body. The TOFD flaw-detection wall-climbing robot can climb on curves like a ball tank and a pipe wall to detect welding defects; meanwhile, the obstacle crossing ability of the robot is high, in the detection process, the robot is stable and reliable in location, and the detection precision is improved; meanwhile, risks brought to the artificial detection is further reduced, the environment adaptability of the detection robot is improved, the detection range is expanded, and intellectualized and high-standard detection work is achieved.

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...
