Abstract
The utility model discloses a rail profile gauge which is provide with a light emitting source and a laser displacement sensor, wherein the output of the laser displacement sensor is connected with a single chip machine, and the output of the single chip machine is respectively connected with a display and an alarm device. The light emitting source irradiates on a rail, a reflected light signal is collected from the surface of the rail through the laser displacement sensor, the captured light signal is converted into a digital signal which is then processed by the single chip machine, a digital signal corresponding to the rail abrasion loss (minus 11 mm to plus 11 mm) is converted by the single chip machine, and the result is finally displayed by the display; when the rail wear volume reaches the limit, an alarm signal is output by the single chip machine and an alarm is sent out by the alarm device. The rail profile gauge has the advantages of simple structure, low cost and convenience in operation and the like, particularly, stepping detection can be achieved, and the problem of low detection precision due to single-point detection is avoided.
Description
Technical field
The utility model relates to a kind of rail abrasion detector, especially a kind of simple in structure, cost is low, easy to operate, can realize the rail abrasion detector that stepping detection and precision are high.
Background technology
Along with train speed, freight volume and the heavy raising of axle, the wear problem on rail surface also becomes increasingly conspicuous, in case the rail serious wear will cause train that safety misadventures such as derailing take place, needs regularly to detect the rail abrasion degree for this reason, promptly detects the rail surface planarity.At present, known rail surface abrasion detector mostly is defect-detecting equipment or the easy physical detection device that Europe produces, and the former structure complexity, involves great expense, and requires operating personal to have higher operant level; Though but latter's accuracy of detection simple in structure is not high, it is bigger influenced by the subjective factor of survey crew, can not obtain best detection effect.
Summary of the invention
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, provide a kind of simple in structure, cost is low, easy to operate, can realize the rail abrasion detector that stepping detection and precision are high.
Technical solution of the present utility model is: a kind of rail abrasion detector, it is characterized in that: be provided with illuminating source and laser displacement sensor, the output and the micro controller system of laser displacement sensor join, and the output of micro controller system is joined with telltale and warning device respectively.
The set illuminating source of the utility model is radiated on the rail, gather the reflected light signal on rail surface by laser displacement sensor, and the optical signal of being caught is converted to digital signal transfers to micro controller system and handle, by micro controller system converse with the rail abrasion amount (11mm ~+11mm) cooresponding digital signal, show by telltale at last; When the rail abrasion amount reached capacity, the micro controller system output alarm signal was reported to the police by warning device.Have simple in structure, cost is low, advantage such as easy to operate, can realize that especially stepping detects, and avoids single-point to detect the low problem of existing accuracy of detection.
