ARRANGEMENT AND METHOD FOR MEASURING AND CORRECTING THE LINE OF A TRACK

摘要

The invention relates to an arrangement and method for measuring and correcting the line of a track. The method comprises forming an optical reference beam between an emitter on an emitter bogie and a position-sensitive receiver on a measuring and correcting car, moving the measuring and correcting car for a measurement interval in sequences of a desired length towards the emitter bogie, monitoring the movement of the hitting point of the optical beam by the position-sensitive receiver, measuring lateral inclination of the track, positioning the position-sensitive receiver in relation to the track between the sequences of moving, and measuring the instantaneous values of the position of the hitting point of the optical beam and the inclination of the track, and using the measurement data for the shifting operations directed to the track. The method further comprises measuring the position of the measuring and correcting car in the longitudinal direction of the track, which measuring is combined with position-sensitive optical measuring effected substantially without clearance in relation to the track for measuring the three-dimensional coordinates of the track substantially at the point of the track to which corrective shifting operations are directed.
