Abstract
The invention relates to a railway steel rail measuring device and especially relates to a device for accurately detecting the abrasion of a railway steel rail. Under the ancillary shoring effect of a support bar (1), a data acquiring and processing unit (2) controls a power mechanism (5) to drive a laser displacement sensor (6) to move at a uniform velocity along a guide rail mechanism (4) provided with a raster displacement sensor (3). The laser displacement sensor (6) and the raster displacement sensor (3) are used for respectively measuring the profile size of a steel rail and the lateral movement amount of the steel rail in real time. A reflective mirror mechanism (7) and the laser displacement sensor (6) cooperatively complete the measurement on the size of the rail jaw of the steel rail. The data acquiring and processing unit (2) analyzes and processes data to accurately calculate and store the abrasion value of the railway steel rail. According to the technical scheme of the invention, through measuring the rail jaw of the steel rail, the effective location of the measuring basis is realized. Therefore, the abrasion value of the railway steel rail can be accurately calculated. The measurement accuracy of the abrasion of the railway steel rail can be greatly improved.
