摘要： PURPOSE:To perform flaw detection by the same ultrasonic flaw detector even when there is some difference in level between a guide rail attachment position and a flaw detection position, by allowing a probe holder held by an arm attached to a driver to slide vertically. CONSTITUTION:The ultrasonic flaw detector consisting of the driver 5 and the probe holder 7 holding the arm 4 and probe 3 performs flow detection along the girth weld line 10 between a pressure container nozzle 8 and a safe end 9. At this time, it is necessary to attach a guide rail 2 to a tube body 1 by the structure at the flaw detection position, so the probe holder 7 has the structure capable of absorbing the difference in level due to the difference in tube diameter between the tube body 1 and nozzle side 8. The probe holder 7 is fitted to the arm holding part 11 through a set screw 12 and a slide hole 13 is formed in the probe holder 7 to make a height adjustment freely.
摘要翻译：目的：即使在导轨安装位置与探伤位置之间存在一定程度的差异的情况下，也可以通过同一个超声波探伤仪进行探伤，通过使连接到驾驶员的手臂保持的探头支架垂直滑动。构成：由驱动器5和保持臂4和探头3的探针支架7组成的超声波探伤仪在压力容器喷嘴8和安全端9之间沿着环形焊接线10进行流量检测。此时，需要通过在探伤位置处的结构将导轨2附接到管体1，因此探针保持器7具有能够吸收由于管体1和喷嘴之间的管直径的差异而导致的水平差异的结构探头保持器7通过固定螺钉12装配到臂保持部11，并且在探针保持器7中形成滑动孔13以自由地进行高度调节。

摘要： PURPOSE:To facilitate the following of the action of a driver along with a simple construction by arranging a pulley adapted to allow free delivery of a cable connected to a probe driver to eliminate the human intervention in the cable treatment. CONSTITUTION:A cable 2 connected to a driver 1 passes through a fixed pulley 3 provided at the upper end of a rail 5 with a support plate 4. This cable 2 passes through a mobile pulley 7 moving on a guide pole 8 supported with supports 10 and 11 mounted on a shield wall 14 of a nuclear reactor near a pressure vessel thereof, temporarily fastened on a fixed pulley 12 mounted at the upper end of said wall 14 with a fixing base 13 and then, connected to an equipment. As the driver 1 moves on the rail 5 for automatic flaw inspection of the pressure vessel of a nuclear reactor, the cable 2 is pulled simultaneously. Since the cable 2 is temporarily fixed on the fixed pulley 12, a force intended to feed a necessary length works on the pulley 7 to move it on the guide pole 8 whereby the cable is delivered by the necessary length.

摘要： PURPOSE:To absorb thermal expansion of a rail and vibration thereof due to earth quake by restricting motions other than vertical and radial ones in combination with a spring. CONSTITUTION:A 4-joint line ABCD is a main component. The joint A is fixed on a support 21F of a rail 3 while the joint C is fixed on a gamma shield 6 with a bracket 22. Spring hooks 23 and 24 are mounted on the joints B and D respectivly in such a manner as to be free to rotate and a spring 25 is interposed therebetween. As the rail 3 expands thermally, the point A is constrained in the direction X but free in the direction of Y+Z. Whenever the point A is moved to reduce the distance between A and B, it is returned by a reaction force of a spring 25. Extending the distance causes a sleeve 26 to hit against the spring hooks 23 and 24 while reducing it beyond a fixed range causes the spring hooks 23 and 24 to hit against stoppers 27 and 28. In this manner, any such an attempt is restricted.

摘要： PURPOSE:To easily adjust the operation range of the rotary shaft by replacing a piece, which is detachably fitted, with a piece of optional size. CONSTITUTION:A striker 9 rotates around the center axis of the rotary shaft 3 to strike the piece 11. When the rotary shaft 3 is further rotated clockwise after the striker 9 strikes on the piece 11, the striker 9 and piece 11 rotate around a fixed shaft 8 in one body. When the rotary shaft 3 is further rotated clockwise, the piece 11 strike on a stopper 13 and its movement is restricted, thereby stopping the rotation of the rotary shaft 3. When the rotary shaft 3 is rotated counterclockwise from its neutral state, the strike 9 and piece 11 strike each other to rotate in one body and strike on the stopper 12, thereby stopping the rotation of the rotary shaft 3. The operation range of the rotary shaft 3 is adjusted by replacing the piece 11 with a piece of optional sized.
