Claims

[Scope of utility model registration request]

An ultrasonic probe installed so as to face a pipe or rod-shaped material to be inspected having a circular cross section being conveyed on a conveyance line; A test in which a standard defect is provided to calibrate the sensitivity of the ultrasonic probe, the position where the probe is equipped with the copying mechanism, and the probe facing the material to be inspected. a movable cart that moves between a position facing the test piece; a frame that supports the test piece as a calibration device; a first plate connected to the frame via a first rotating shaft; a second plate connected to the first plate via a second rotating shaft; and a second plate connected to the second plate via a first moving mechanism movable in a direction parallel to the conveying direction. The third plate is connected to the third plate via a second moving mechanism that is movable in a direction perpendicular to the direction of the moving cart and perpendicular to the transport direction, and is connected to the same fixed body as the transport line. When the probe is taken offline from the conveyance line to calibrate the sensitivity, the position of the standard defect provided on the test piece and the position of the probe are Rotate the test piece around the rotation axis of By bending the test piece around the second rotation axis in the same plane as the test piece, and by using the moving cart and the second moving mechanism in two directions perpendicular to the conveying direction of the test piece, An ultrasonic probe device equipped with a calibration device that has a function of causing a positional shift between the ultrasonic probe and the ultrasonic probe and confirming that a predetermined tracking performance is obtained by the scanning mechanism.
