摘要

Traditional inspection devices based on magnetic flux leakage for pipe inspection require the use of several yokes to cover the whole circumference of the pipe, where axially oriented cracks are usually left uninspected and the number of yokes used, makes the device too heavy. In this work, a design of the mechanical structure of an external inspection robot is presented. The robot moves in circumferential direction coupling a single MFL yoke in the pipe wall and move in the axial direction of the pipe to cover new inspection areas. In this mechanism, the yoke also rotates in order to detect any possible crack orientation. The robot has the ability to adapt to pipes between 6 and 12 in. diameter. A modeling of the forces that supports the structure is presented.
