摘要： PURPOSE:To make it possible to insert the titled apparatus in a pipe even if the diameter of the pipe is relatively small and there are a step part and a bent part in the pipe, by providing a fiberscope having an objective lens provided to the leading end part thereof and a rotary pendulum supporting said objective lens in the vicinity of the center of rotation thereof. CONSTITUTION:A sensor head 10 is constituted by providing a fiberscope 23 having an objective lens 21 at the leading end thereof, a rotary pendulum 12 supporting the lens 21 and a sensor head frame 11 receiving said pendulum 12 and running through a pipe by the push-in force of an elastic body 20. The pendulum 12 is fixed to the frame 11 through a bearing 13 so as to freely rotate around the center line of the frame 11 and the lens 21 is allowed to always coincide with a gravitational direction in an up-and-down direction even if the frame 11 is distorted when inserted in the pipe. In order to prevent the excessive distortion of the scope 23 and the impartment of distortional impact due to the excessive twist or abrupt rotation of the pendulum 12 by vibration during running, the pendulum 12 and the frame 11 are connected through a damping apparatus 14 and prevents the hypersensitive shaking of the pendulum 12.

摘要： PURPOSE:To enable running without trouble even in a vertical pipe or piping having a steep gradient having not only a relatively small diameter but also undulation or a step part therein, by providing a stretching apparatus following the undulation or step part of a pipe inner wall and pressing the pipe inner wall by arbitrary force. CONSTITUTION:An endless track 14 is driven by a running drive motor 10 to allow a running vehicle to run and, in the going-up in a vertical pipe or piping having a steep gradient, a guide wheel 26 is stretched to the inner wall of a pipe body 3 so as not to separate the endless track 14 from said inner wall to hold a posture. The guide wheel 26 is attached to a guide wheel holder 25 which is, in turn, fixed to a spring holder 28 through a spring 24 and the pressing force of the guide wheel 26 is detected by the pressing force detection sensor 40 for detecting the extending and contracting quantity of the spring 24. The spring holder 28 can be slid up and down by the rotation of a spur gear 21 and a spring holder feed screw 22 using a guide wheel driving motor 20 as a drive source and the pipe wall pressing force of the guide wheel so as to adapt to a piping shape such as even undulation, a step part or curve in a pipe.

摘要： PURPOSE:To detect the cracking of piping automatically with good accuracy, by constituting the title probe of a sensor unit, an amplifying unit and a connector unit all of which have a spherical shape. CONSTITUTION:An ultrasonic probe 1 is constituted of a sensor unit 2, an amplifying unit 3 and a connector unit 4 all of which have a spherical shape. When the coupler 19' supplied from a tube 21 is supplied to the coupler supply passage 13 of the unit 2 through a coupler holder 19, a support member 8 moves in an opposite direction against the energizing force of a coil spring 14, and the fulcrum part 8' of the member 8 and the leading end of an ultrasonic probe 10 are brought into contact with the inner surface of piping 30. Herein, the coupler 19' is supplied between the probe 10 and the piping 30 and the ultrasonic wave emitted from the probe 10 is transmitted to the piping 30 and the reflected wave from the piping 30 is received by the probe 10. The received signal enters the amplifier of the unit 3 through a cable 7 to be taken out to the outside through cables 6, 22. When the supply of the coupler is stopped after the finish of measurement, the members 8, 15 are drawn in a main body 9 by the recovery force of the spring 14.

摘要： PURPOSE:To enable the movement of the titled apparatus even if there is a step part or a bent part such as a joint of a small-caliber piping and to perform accurate flaw detection by closely contacting a probe with the piping at the time of flaw detection, by closely contacting the probe moving through the piping to detect the flaw thereof with the inner wall of the piping by a pressing body. CONSTITUTION:The titled apparatus is constituted of pressing bodies 10, 11 grasping a probe 1 to press the same to the inner wall of piping 30 and a flaw detection frame 20 receiving the same. The pressing bodies 10, 11 are provided to three places over the entire periphery of the frame 20 and a tension spring 12 is compressed by the pressure of the flaw detection medium 3 flowing in a medium pressure feed hose 22 to be closely contacted with the inner surface of the piping 30. By this method, the gap between the probe 1 and the inner wall of the piping can be reduced. Because the frame 20 moves so as to slide in the piping 30 by the pushing-in and pulling-back of an elastic body 21, said frame 20 has a spherical or oval appearance shape so as to be able to smoothly run even if there are a joint, a step part, bent part, etc., in the piping: the pressure of the flaw detection medium 3 is lowered at the time of movement and the pressing body 10 is received in the flaw detection frame 20 by the recovery force of the tension spring 12 to protect the probe 1 from the collision with the obstacle in the piping.

摘要： PURPOSE:To smooth running in small piping, by providing a plurality of infinite tracks at a predetermined interval in the circumferential direction of a pipe inner wall. CONSTITUTION:A running apparatus in a pipe consists of a running driving part for driving infinite tracks 15 and the running vehicle frame 20 receiving the running driving part. The running driving part has the running driving motor 10 mounted to a running vehicle 1 as a drive source and the tracks 15 are driven by rotating drive wheels 12 through transmission gears 11. Because the posture of the running vehicle 1 changes in the running when there is a step part in piping 3, the tracks 15 are provided at four places on the entire periphery at predetermined intervals in the circumferential direction of the pipe inner wall so that the tracks 15 are ridden on the step part even if the running vehicle 1 takes any posture. By this method, the running apparatus in the pipe, runnable even if the running vehicle takes any posture by the undulations, step parts or bendings in the pipe, is obtained.
