Abstract
PURPOSE: To enable to simultaneously find cracks for deep and shallow parts in the rod, by providing the slope probe tilting the chute and vertical probe to the side by an angle θ, which are slided with the external circumference of rod, and the carrier moving the rod while turning.
CONSTITUTION: The rod 1 is placed on the carrying line 2 and carried forward while being turned with the carrier 3, and when the front end of the rod 1 is detected for the arrival possible for crack finding, the head 4 is dropped by the drive unit 6 in contact with the external circumference of the rod 1. In this case, the chute 8 of the head 4 bottom is in contact with the external circumference of the rod 1, and even with bent rod 1, the variance can be absorbed with the cushion 7. While the head 4 is in contact with the external circumference of the rod 1, the water in the tank 10 flows down from the holes 18, 19 of the chute 8, and ultrasonic waves are transmitted from the slope probe 17 tilted by an angle θ, and from the vertical probe 16, and the ultrasonic waves transmitted from the rod 1 is received by using the same probes.
