PURPOSE:To feed an ultrasonic probe into the deep part of an inaccessible pipe group and to make possible the ultrasonic flaw detection of the pipe group which is heretofore impossible by incorporating the mechanism consisting in attaching traveling rails as a supporting structure to support the pipe group itself and running a slider thereon so as to bring a driving device for detection near to the pipe. CONSTITUTION:The device is constituted of a driving device 4 for an ultrasonic probe 1 which carries the probe and rotates the probe around a pipe 900 which is an object to be inspected, a traveling device 6 which moves the device 4 from the pipe to the pipe, a control device 5 which controls the device 4 and the device 6, an ultrasonic flaw detector 2 which transmits and receives the signal between the probe 1 as well as a recorder 3 which records the result of the flaw detection. The device 6 is constituted of the slider 604 holding the device 4, two pieces of the guide rails 605 which guide the traveling of the slider 604, a feed screw 606 for driving the slider 604, clampers 602 and 603 for clamping the rails 603 to the pipe and a motor 601 for driving the screw 606. |
