METHOD OF AND DEVICE FOR DETERMINING SPATIAL PARAMETERS OF RAIL TRACK Russian patent published in 2005 - IPC

FIELD: railway transport.

SUBSTANCE: invention relates to methods of continuous recording of spatial position of track gauge. Proposed method includes recording of information from pickups of rail-to-rail space, covered distance, current course angle, longitudinal and cross grades at vehicle running and calculating of current coordinates of track gauge using data of pickups. Recording of course angle and longitudinal grade from said pickups and determination of current coordinates X_i,Y_i,H_i is carried out for one of rail lines relative by any initial direction in horizontal plane at measuring pitch 1. Coordinates of point i_m corresponding to middle of straightline section connecting extreme points i₀ and i_n are calculated by measured coordinates of extreme points for each preset section of track P_i. Deflection of rail in horizontal and vertical planes, δ_ihδ_iv respectively, is determined by difference between calculated coordinate of indicated point and measured coordinate of corresponding point. Device for determining spatial parameters of rail tracks has running truck including support wheel and first and second measuring wheels and odometer wheel arranged on one axle over one of rail lines. Support wheel is connected with measuring wheels by link installed at angle of 90° relative to direction of running. Track gauge width pickup is installed on said link. Distance pickup is mounted on odometer wheel. Course and roll indicator is installed on axle connecting measuring wheels. Outputs of distance pickups, track gauge pickup and course and roll indicator are connected with computer through controller.

EFFECT: enlarged functional capabilities, with possibility of determination of relative position of track section in vertical and horizontal planes (level and sag), together with determination of spatial coordinates.
