INSPECTION DEVICE OF RAILROAD TRACK

摘要

PURPOSE: An inspection device of a railroad track is provided to examine a height of two tracks according to a movement distance by sensing abnormality of the tracks with by a laser diode sensor. CONSTITUTION: A device for examining abnormality of a railroad track comprises a track state sensor(10) consisting of a light emitting unit(11) and a light receiving unit(12); a movement distance measurer(20) for measuring a distance from a starting station to a current position; and a microcomputer(50) for storing in a memory unit(30) a track height state value of the track state sensor(10) corresponding to a movement distance, and outputting it to a display unit(40). A special track examining train is not required, and thus the railroad track examination time is not restricted to the nighttime when trains are rarely serviced.
