Deformation quality detector for railway track

Abstract

The invention relates to a deformation quality detector for a railway track, and relates to the technical field of railway detection. The deformation quality detector comprises a trolley and a plurality of rollers rotatably arranged at the bottom of the trolley, the rollers comprise a fixed pulley rotating on one track and a movable pulley rotating on the other track, and the fixed pulley and the movable pulley are staggered along the length direction of the track; the movable pulley slides on the trolley in the direction perpendicular to the length direction of the track, a pigment box is arranged on the trolley, a marking pipe for conveying pigment towards the position below the trolley is arranged on the pigment box, a switch valve is arranged on the marking pipe, and the switch valve is used for communicating the pigment box with the marking pipe after being pushed by the movable pulley. The fixed pulley and the movable pulley are arranged in a staggered mode, a switch valve is opened through sliding of the movable pulley on the trolley relative to the fixed pulley, so that the pigment box and the marking pipe are connected, pigment flows out to mark the bent rails, the two rails with the same bending are detected, and therefore the rail detection error is reduced.

Description

technical field [0001] The present application relates to the technical field of railway detection, in particular to a deformation quality detector for railway tracks. Background technique [0002] At present, my country's road construction is becoming more and more comprehensive, and the increase of railways has made more areas accessible to trains. In order to meet people's daily travel needs, the development of trains to high-speed trains has greatly shortened the travel time on the railways, so more roads have been laid. The railway track supports the operation of high-speed trains. [0003] Under long-term use of the railway track, the track will be slightly deformed, and the deformation will gradually increase over time. In order to detect the deformation of the track, it is usually to use equipment such as an infrared rangefinder to measure the distance of the opposite points on the two tracks, so as to detect whether the distance between the two parallel tracks on th...

Problems solved by technology

[0004] In the above-mentioned related technologies, the inventor believes that when detecting the rails, it is easy to ignore the situation that the two rails produce the same deformation at the same time in the process of detection by infrared ranging. In this case, the deformation between the two rails The distance has not changed, but the track has been deformed, making the data value measured by infrared ranging unchanged, resulting in errors in track deformation detection
