Method and system for correcting the position in the plane of the rail axis of mobile measuring and control devices

Abstract

The subject of the application is a method and system for correcting the position of mobile measuring and control devices in the plane of the rail axis. The method consists of stages in which: a measuring vehicle equipped with a mobile measuring device (2) containing measuring transducers located on the tested railway rail (1) or slightly above it, attached to the chassis (R) of the measuring vehicle by means of a suspension (3) enabling perpendicular displacement of the transducers of the mobile measuring device (2) relative to the vertical axis of the tested railway rail (1); then, using a laser rangefinder (6) attached to the chassis (R) of the measuring vehicle, the distance D between the laser rangefinder (6) and the lower part of the lateral working surface of the railway rail head (1), below the area of ​​cooperation with the vehicle wheels, is set in motion,by emitting a one-dimensional laser measuring beam (7); then information about the distance D is transmitted to the automation control module (5), by means of which the correction value of the position of the transducers of the measuring device (2) is determined; then, by means of the correcting drive (4), the position of the transducers of the measuring device (2) is corrected by the determined value in the vertical plane of the axis of the railway rail (1). The system has transducers of the mobile measuring device (2) located on the tested railway rail (1) or slightly above it, and a suspension (3) is attached to its upper part, enabling perpendicular displacement of the transducers of the mobile measuring device (2) relative to the axis of the tested railway rail (1), which suspension (3) is attached to the chassis (R) of the measuring vehicle,wherein the transducers of the measuring device (2) are connected to a correction drive (4) connected to an automation control module (5) for determining the correction value, which module is connected to a laser range finder (6) for measuring the distance D between it and the lower part of the lateral working surface of the railway rail head (1), below the area of ​​cooperation with the vehicle wheels, wherein the laser range finder (6) is attached to the chassis (R) of the measuring vehicle, and the one-dimensional laser measuring beam (7) is directed towards the lower part of the lateral working surface of the railway rail head (1), below the area of ​​cooperation with the vehicle wheels.,
