Device and method for measuring roughness of slab track paving layer

Abstract

The invention discloses a device for measuring the roughness of a slab track paving layer and a method for measuring the roughness. The device includes a frame and a measuring component. A first moving component and a second moving component are arranged between the measuring component and the frame. The measuring component passes through the first A moving component moves along the X-axis in the frame, and the measuring component moves along the Y-axis in the frame through the second moving component; the measuring component includes a probe that can move along the vertical direction and a depth gauge that can display the movement amount of the probe; the measuring method Realized by the above-mentioned device. The present invention can conveniently adjust itself to a state completely parallel to the surface to be measured when in use, and can also realize continuous measurement of all positions of the surface to be measured, and the measurement data can be displayed on external electronic equipment in real time. The coordinates and roughness are recorded, which improves the measurement efficiency, and the obtained data can completely reflect the roughness distribution of the surface to be measured, which greatly reduces the measurement error and labor cost.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a device for measuring the roughness of a slab track paving layer and a method for measuring the roughness of a slab track paving layer. Background technique [0002] The rapid development of the rail transit industry has not only led to rapid economic growth, but also greatly improved people's quality of life. In the field of track engineering, ballastless track has been widely used due to its high smoothness, high stability and less maintenance. Therefore, the refined research on the performance of ballastless track has become the focus of track engineering. [0003] The new ballastless track structure system consists of track slabs, damping cushions and concrete paving layers. With the increase of the surface roughness of the slab ballastless track pavement layer, under the action of the train load, the surface tensile force on the track slab will gradually increase.

AI Technical Summary

Problems solved by technology

[0004] (1) The existing measuring device cannot be completely parallel to the surface to be measured, which brings unnecessary errors to the final measured roughness data;

[0005] (2) The existing measurement devices cannot realize continuous measurement, and generally measure randomly by selecting sampling points. Sex, and the manipulation is more cumbersome;

[0006] (3) The existing measuring device needs to manually record the coordinate points and roughness, the work is cumbersome, the measurement takes a long time, and it is impossible to realize the real-time display of the measurement data on the computer and other equipment, which is not conducive to the subsequent processing of the data;

[0007] (4) The movement of the existing measuring device on the surface to be measured is limited. After the measurement of a point is completed, the measuring probe often needs to be lifted and then moved. The operation is cumbersome and the measurement efficiency is greatly reduced.
