TOFD flaw-detection wall-climbing robot

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 locat
