Description of the Related Art A local immersion type ultrasonic flaw detector using a split type probe for flaw detection of a welded seam portion of a UOE steel pipe has several pairs of probes as shown in FIGS. 4 (A) and 4 (B). 11 is attached. As the flaw detection method, the probes 11 are arranged on the left and right sides of the welding seam 21 on the steel pipe 1, and ultrasonic waves are made to enter the pipe by using water as a contact medium, and the steel pipe 1 is continuously moved while moving in the longitudinal direction by fixing the probe. The general method is to detect flaws. FIG. 5 is a diagram showing a flaw detection flow of a conventional submerged ultrasonic flaw detector (hereinafter referred to as an ultrasonic flaw detector) using a split type probe.

探傷が完了する。In FIGS. 4 and 5, the steel pipe 1 starts to move in the longitudinal direction. The plurality of pipe end detectors 19 mounted on the elevating frame 2 sequentially detect the pipe ends of the steel pipe 1, and the plurality of support arms 18 corresponding to the pipe end detectors 19 sequentially descend, and at the same time the support arms 18 move upward. Probe 1 at the supporting tip
The manipulator 9 holding 1 moves down. Probe 11
Starts to detect flaws on the upper surface of the steel pipe 1 by its own weight.
Next, when the proximity sensor 17 included in the holder 10 that holds the probe 11 detects that the pipe end bottom of the steel pipe 1 moving in the longitudinal direction is detected, the flaw detection is stopped and the support arm 1

Since the probe can follow freely in the longitudinal and lateral directions, it will bend freely unless the entire surface of the probe is placed on the steel pipe, so the probe 11 must be raised and retracted at a position that does not touch the pipe end. I won't. As a probe holding mechanism, there is a mechanism disclosed in Japanese Utility Model Laid-Open No. 4-90958. Japanese Utility Model Laid-Open No. 4-90958 is a probe holding mechanism in which a universal joint is inserted between the probe holding portion and the vertical tracking mechanism.

In order to imitate the upper surface of the
The manipulator 9 must be lowered at a timing when the entire surface of the probe 11 is surely placed on the upper surface of the steel pipe 1 because it can freely follow in the left-right direction. In the conventional apparatus in which the pipe end detector 19 detects the pipe end and the manipulator 9 descends to start the flaw detection at the start of flaw detection, in the conventional device, the probe is pierced at the pipe end due to the detection accuracy of the detector. 11
In order to prevent breakage of the pipe, the pipe end detector 19 must be installed at a position where it can be surely started to detect flaws slightly from the pipe end, and an undetected portion is generated at the pipe end.

ある。Further, even at the final end of the flaw detection, it is possible to freely follow it. Therefore, if the manipulator is lowered to the final end, it will be free when the probe partially touches the pipe end due to its own weight copying. It will bend and it will not be possible to make a good copy. Therefore, the probe has to be raised before the final end, and an undetected portion is generated at the pipe end. Further, there is a problem that the pipe end portion is bent and vibrated more than the body portion, and the flaw cannot be reliably detected due to the followability of the probe. Further, the probe holding mechanism disclosed in Japanese Utility Model Laid-Open No. 4-90958 only solves the problem of the probe with respect to vertical and horizontal displacement of the steel pipe, and cannot solve this problem. The present invention is an ultrasonic flaw detection device which solves this problem and is capable of performing flaw detection on the pipe end portion reliably and capable of flaw detection up to the end portion of the pipe end.
