摘要： PROBLEM TO BE SOLVED: To detect in an early stage a surface flaw and an internal lateral laceration so as to take measures for repairing and replacement of a rail, ensuring a safe travelling.SOLUTION: An exciting coil and two detection coils arranged apart in a longitudinal direction of an inspection rail by sandwiching the exciting coil are arranged above a head part of the inspection rail by a liftoff. Both of the detection coils are reversely wound and connected in series, and an AC magnetic flux generated from the exiting coil is applied to the inspection rail so as to generate an eddy current in the inspection rail. An amplitude of the induced voltage generated based on the eddy current is detected by the two detection coils regardless of whether the flaw exists or not, and an amplitude difference between the detected amplitude in the case that no flaw exists and the amplitude of the fluctuating induced voltage based on the eddy current fluctuated by receiving the influence of the flaw in the case that the flaw exists is subtracted and detected by the reversely wound detection coils, and the presence or absence of the flaw is detected from this amplitude difference, and the surface flaw and the lateral laceration of the inspection rail is detected.

摘要： PROBLEM TO BE SOLVED: To measure fluctuation of a long rail, which is performed by manual operation and its working efficiency is conventionally low, similar to a rail joint opening measuring in a train traveling at high speed.
SOLUTION: A rail side laser oscillator is driven by a drive signal transmitted from an on-vehicle transmitter and outputs a leveling string substitute laser beam, and an on-vehicle light receiving sensor receives the leveling string substitute laser beam and outputs a leveling string substitute signal. An on-vehicle identifier sensor detects a punch mark substitute and a rail joint opening/long identifier on the rail and outputs a punch mark substitute signal and a rail joint opening/long determination signal. A rail joint opening measurement and a long measurement are changed over based on the rail joint opening/long identifier signal, an on-vehicle laser doppler sensor outputs a doppler signal, an on-vehicle rail joint opening identifier sensor outputs the rail joint opening identifier signal. When it is changed over into the long measurement based on the rail joint opening/long determination signal, the fluctuation of the long rail is measure based on the leveling string substitute signal, the punch mark substitute signal, and the doppler signal, and when it is changed over into the rail joint opening measurement, the rail joint opening is measured.

摘要： PURPOSE:To perform accurate measurement without contact by performing amplitude modulation for laser light for identifying an opening of a rail joint, amplifying only the modulated light of the reflected light from a rail, taking out the modulated light, identifying the modulated light form solar light, and performing detection and amplification. CONSTITUTION:Trapping laser light is applied on an upper surface 2 and a chamfered surface 1c of a rail 1 from a laser doppler sensor. The scattered light from the upper surface 2 and the chamfered surface 1c is received by the laser doppler sensor, and the doppler signal is obtained. In addition, laser light (d) for identifying an opening of rail joint is otherwise applied on the upper surface 2 and the chamfered surface 1c from the direct upper side from a sensor 4 for identifying the opening of rail joint. Reflected light (e) from the upper surface 2 and the chamfered surface 1c is received by photodetectors 4a provided at the front and rear directions of the rail 1. The length of the opening of rail joint is computed on the basis of the number of the pulses of the doppler signal and the pulse interval. At this time, the laser light (d) undergoes amplitude modulation. Only the modulated light is taken out of the scattered light received by a photodetector 4a. The modulated light is identified from the solar light, detected and amplified. The modulated light is outputted as the signal of the opening of rail joint.

摘要： PROBLEM TO BE SOLVED: To obtain a deviation measuring apparatus of a low cost and a small size capable of mounting in a business vehicle by measuring a deviation state of a trolley wire by using a discriminating method based on a level or the like of an output signal of a sensor. SOLUTION: Detection signal data of sensors A to D stored in a memory means are read by a processing means such as a personal computer or the like, and a graph indicating, for example, the relationship between a moving distance or time of a vehicle and a level and an amplitude of output signals of the sensors A to D is output from a print or display means or the like. An operator decides a trolley wire based on the graph or the like by using a predetermined discriminating method. Thus, a place in which a deviated distance of the wire is a first distance x or above can be discriminated. Since number and installing positions of the poles installed between stations are known in advance, substantial positions of the places in which the wire is deviated at the first distance x or above can be discriminated.

摘要： PROBLEM TO BE SOLVED: To solve the problem that fluctuation quantity measurement of a rail requires much labor and time, and has poor working efficiency and problematic measurement accuracy. SOLUTION: In this method, a laser beam is outputted from a laser oscillator installed on a reference body fixed on the side of the rail, and the laser beam is used as a substitute for a leveling string, and an identifier installed on the rail is photographed on a screen by a camera loaded on a vehicle by using the laser beam an a trigger, to thereby measure the rail fluctuation quantity from the fluctuation of the image position of the identifier on the screen. A clear image can be photographed even under sunlight by combining emission from a stroboscope with an electronic shutter of the camera.

摘要： PURPOSE:To enable a chamfered inclined surface to be measured as a rail length even if it is located at starting and ending edge parts of the rail. CONSTITUTION:A laser beam (a) for Doppler is emitted from a laser Doppler sensor 3 to an upper surface and a chamfering part of a rail 1 and then a Doppler signal is output from its scattering light (b). On the other hand, a laser beam (d) for identifying gap is emitted from a sensor 4 for identifying gap to the upper surface 2 and the chamfering part from directly above and then a reflection light (e) which is reflected skewly is received by either of two light receivers 4 at a chamfering part 1c or the laser beam (d) for identifying gap is emitted to the upper surface 2 and the chamfering part skewly for receiving a reflection light (e) which is reflected directly above at the chamfering part using a light receiver.
