| Zusammenfassung: | The present invention discloses a steel rail flatness and torsion detection device and method. The device comprises a plurality of spectral confocal displacement sensors and a plurality of linear laser contour sensors. The spectral confocal displacement sensors are symmetrically arranged at two sides of a steel rail and two sides of the bottom portion of the steel rail to measure distances from the side of a rail head of the steel rail and measured points at the bottom portion of the steel rail to the sensors; the linear laser contour sensors are put at the top portion of the rail head of thesteel rail to collect a steel rail tread curve; and the spectral confocal displacement sensors and the linear laser contour sensors are connected with a data collection storage to perform analysis andprocessing to obtain the flatness and torsion of the steel rail. The detection method mainly employs the spectral confocal displacement sensors and the linear laser contour sensors to collect geometrical parameters of the sur |
