摘要： PURPOSE:To detect a directional defect and discriminate between a shape echo and a defect echo by providing a converter so that an ultrasonic wave is transmitted to and received from a part to be inspected simultaneously and also independently. CONSTITUTION:Transmitted pulses generated by a pulser 51 are supplied to one of converters 31-34 selectively by a multiplexer (MPX) 52 and sent as an ultrasonic wave to the part 43 to be inspected. One of echoes that the converters 31-34 receive from a defect, etc., is selected by the MPX 53 and amplified by a receiver 54 on a frequency selective basis. Then, a gate 55 selects only a signal of time when the signal from the part 43 to be inspected is expected to arrive with time. Then, a defective echo discriminating device 8 calculates the position of a reflection source for the echo from a beam route, amplitude data, data on a flaw detection direction, etc., and stores it together with the respective data to discriminate the defect and decide on its direction. Therefore, the defect is detected speedily and securely.

摘要： PURPOSE:To detect a vertical cracking defect at a high speed without lowering flaw detection precision by arranging only one or two adjacent converters at a distance of one skip from a part to be inspected. CONSTITUTION:Converters 15-18 form the 1st group and converters 19-22 form the 2nd group. Further, the 1st and the 2nd groups cover flaw detection areas I and II. In this case, the converters 17 and 18 in the 1st group and the converters 21 and 22 in the 2nd group are arranged at a distance of one skip from their original positions. When ultrasonic flaw detection is performed by the 1st and the 2nd groups, the transmitting/receiving operation of the converter 15 is performed by the 1st group and then operations of the converters 16-18 are carried out, and flaw detection is performed by a 1-probe method and then flaw detection is performed by a 2-probe method. Thus, the flaw detection is completed and flaw detection by the 2nd group is performed, thus finishing one period of flaw detecting operation.

摘要： PURPOSE: To suck and detach without transmitting a reaction to a support part in suction or detaching a vacuum pad by constituting it in such a state as controlling the pressure of operating fluid, at least, into two stages. CONSTITUTION: A change-over valve 11' feeds high pressure P fluid to a terminal feeding hole 7 through a feeding hole 15 via a change-over valve 11. In this case, the suction pad 5' is drawn to a support rod 1. Secondly, the whole support part 3 is made to approach to the wall surface 6 to a prescribed distance so as to apply the vacuum. Then, when the feeding hole of the change-over valve 11 is shifted to 8, the vacuum pad 5' is pushed toward the wall surface 6 so as to start suction in such a position as bringing the vacuum pad 5' in contact with the wall surface. In this case, the pad 5' is pushed from the back so that as long as the reaction to the support part 3 is moving, it is not generated. Thirdly, when the suction and the contraction of the vacuum pad 5' is completed, the change-over valve 11 is shifted, and when the pressure in the support rod guide part inside is set to the atmospheric pressure, the vacuum is turned off, the feeding hole of the change-over valve 11 is returned to 15, and the reaction to the support part 3 is set to zero so that the pad 5' is detached therefrom.

摘要： PURPOSE: To stably travel a frame along a wall surface by providing a slidable guide element to one frame along an arc guide which is provided in the other frame and by constituting the frame center faced to the center of the curved wall surface. CONSTITUTION: An adsorption element 13 of one frame 1 is adsorbed to a sphere of a prescribed curvature or an R surface 16 and the absorption element 13 of the other frame 2 is detached from the surface 16. An actuator 12 is driven in this state, the frame 2 detached from the absorption element is moved by the relative movement of the drive mechanism 3 of one frame and the drive support part 5 of the other frame. This operation is repeated in the each frame alternately so that the frames 1, 2 are traveled and moved along the surface 16. In this case, though the frame 2 becomes to be inclined to the frame 1, it is followedly rotated by the free rotation of a pin 9 and a roller guide element 10 of the frame 2 is moved along the arc guide 4 of the frame 1. As a result, the center of the frame can be held in such a state as being faced to the center of the curvature of the surface 6 at all times.

摘要： PURPOSE:To securely detect possibility for damage from a conduit system side by connecting a resonating circuit in which detecting current is resonated to vary in high impedance between an underground metal conduit and a corrosion preventing device. CONSTITUTION:Earth points i, i+1,... are provided at prescribed intervals on a conduit 1. On the other hand a detector 2, a power source 3 and resonating circuits 4 are connected to a conduit system 1 at a point i, and the earth side is linked to a corrosion preventing device 7. In the case where an excavator 5 damage the conduit at a damage part 6, the voltage and the current of a signal varies because the impedance is considerably low at this point. This variation is grasped by the detector 2. Further, in regard to the deciding of the damage part 6 time difference of damage signals from each point at which the detector 2 receives is computed at a relay point or at the center. Since the resonating circuits 4 are inserted at each earth part i, i+1, ..., and high impedance is formed for the signals of the power source 3, the current signal is very little from the conduit system 1 to the earth and so the signals go on long distance.

摘要： PURPOSE:To accurately detect the moving position of a traveling vehicle by fitting a revolution indicator to a driven wheel of the traveling vehicle and detecting its traveling distance. CONSTITUTION:An in-tube running device is constituted by coupling a driving wheel, a motor wheel, and a sensor wheel, etc., and travels in a tube to inspect its thickness reduction. The driving wheel 21 gives a driving force through the rotation of a driving wheel 25 by the rotation of a driving shaft 28 coupled with the motor wheel. A pressure spring 33 is put in a frame 26 so as to increase the cohesive force between the driving wheel 25 and tube internal wall, and consequently a pressure frame 32 is pressed against the tube wall through a driven wheel 31. A mark for rotation decision making is stuck on the driven wheel 31, which is united with a sensor for detecting the mark to constitute a driven when revolution indicator 34. This device measures the rate of pulses from the driven wheel revolution indicator 34 to measure the speed or integrates the pulses to measure the traveling distance.

摘要： PURPOSE:To reduce the structure in size and simplify it by providing at least two running cars equipped with an inspecting device and a device which swivels the running cars around a tube. CONSTITUTION:A preceding car 10 runs through the rotation of two infinite tracks 13A and 13B powered by a preceding car driving motor 11 and is coupled through a coupling device 17A which transmits the power of the motor 11. The tracks 13A and 13B are supported on this device 17A in an oscillatory state and follow up a step and unevenness of the internal wall of the tube. A pressing mechanism 14 presses the internal wall of the tube with proper force. Then, the running car 10 and swiveling device 30 are coupled through a coupling device 17B, the oscillation angle of the preceding car 10 is detected by a precesing car attitude detection sensor 19 and attitude detection data on it is transmitted to a controller on the ground through a power transmission cable 1. A trailing running car 20, on the other hand, has basically the same structure and function with the running car 10 and the oscillation angle of the running car 20 is detected by a trailing car attitude detection sensor 29. Thus, the structure is reduced in size and simplified to inspect a small-diameter tube.
