[0003] In the prior art, the steel rail is usually tested by purely mechanical caliper measurement method. The measuring instrument of pure mechanical caliper measurement method is configured according to different rail models. The measuring instrument is clamped to the bottom of the rail, and then the top and side pointers of the instrument are pressed down. Hold the surface of the rail and read the measurement data at this time. However, the measuring instrument of the pure mechanical caliper measurement method has high requirements on the ability of the workers, a large workload, low work efficiency, and is greatly affected by human factors. Long-term use will cause the caliper to wear out. , resulting in a decrease in measurement accuracy and the inability to continuously detect the degree of wear of the entire rail

Abstract
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.
Description
technical field [0001] The invention relates to a rail wear detection device, in particular to a rail wear detector. Background technique [0002] With the rapid development of railways, heavy-duty trains and high-speed trains are becoming more and more important in the railway transportation industry, and the existence of heavy-duty trains and high-speed trains makes the rails wear and deform. When the rails used on the line reach If the degree of serious injury is exceeded, driving safety will be affected. Rail wear can be divided into vertical wear on the top surface of the rail head and lateral wear on the side of the rail head according to the position. The wear detection of the rail should be carried out regularly to ensure the safe running of the train. [0003] In the prior art, the steel rail is usually tested by purely mechanical caliper measurement method. The measuring instrument of pure mechanical caliper measurement method is configured according to different ...
