Railway layered distribution track integrated measuring device

Abstract

The present invention discloses a railway layered distribution track integrated measuring device, comprising: a track smoothness detection device and a monitoring and control data display and monitoring alarm device; the track smoothness detection device is connected with the monitoring and control data display and monitoring alarm device; the track smoothness detection device comprises a high-precision laser measuring device, a measuring target and a reference positioning target; the high-precision laser measuring device and the reference positioning target are respectively fixed on the outside of a line segment to be measured; the measuring target is placed outside the position of the line segment to be measured; the measuring target saves the vertical camber and horizontal deflection measurement results of the line position and the horizontal distance result of the line position in real time to a data memory and timely sends the results to a monitoring center. The railway layered distribution track integrated measuring device has the advantages of high measuring precision, good system working stability, high integration degree, energy saving and high reliability, small size, compactness, portability, and easy operation.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to an integrated measuring device for railway layered distribution tracks. Background technique [0002] With the rapid development of my country's high-speed railway system, the operating speed of trains is getting faster and faster, and the vibration and impact of train power on roadbeds, tracks and bridges is much greater than that of ordinary railways. Since track irregularity is one of the main factors that stimulate train vibration, increase the force of wheel-rail action and affect the stability of train running, in order to ensure the stability, safety and comfort of high-speed railways, the geometric shape of the track must maintain extremely high smoothness, precision and stability. [0003] The traditional measurement method of track smoothness is mainly based on manual work. For example, the main tool used for leveling and superelevation is the railway gauge ruler; the...

AI Technical Summary

Problems solved by technology

[0005] (1) The traditional track smoothness measurement method consumes huge human resources and cannot be widely used;

[0006] (2) The manufacturing cost of large-scale rail inspection vehicles is very high, and the use is cumbersome, which is not convenient for daily line detection and maintenance;

[0007] (3) Most of the portable rail inspection vehicles use the chord measurement method to calculate the long-wave irregularity by measuring the height of the short chord vector, resulting in the multiplication of the measurement error
