The invention discloses a
rail wear detector, which is composed of a
liquid crystal display screen, a driving wheel, a motor, an outer follower wheel, a second supporting pole, an outer
metal baffle,a power switch, a top
metal baffle, a battery, a second
light source, a second camera, a second
infrared range sensor, an SD card storage module, a main control board, a
first light source, a first
infrared range finder, an inner
metal baffle, a first camera, a first supporting pole and an inner follower wheel. The
rail wear detector is arranged on the rail to move along the rail, the rail head top surface and the rail head side surface of the rail are detected through the first camera, the first
infrared range sensor, the second camera and the second infrared range sensor arranged on the railwear
detector, the detected data and the detected images are compared with a standard rail, the
rail wear degree is determined, and when the rail wear is detected to reach a
severe injury degree, aninstrument actively reminds the user.
