A Deformation Quality Detector for Railway Tracks

Abstract

This application relates to a railway track deformation quality detector, which relates to the technical field of railway detection, including a trolley and a number of rolling wheels that are rotated at the bottom of the trolley. The movable pulley, the fixed pulley and the movable pulley are staggered along the length of the track. The movable pulley slides on the trolley along the direction perpendicular to the length of the track. An on-off valve is arranged on the pipe, and the on-off valve is used to communicate with the marking pipe of the paint tank after being pushed by the driven pulley. This application staggers the fixed pulley and the movable pulley, and uses the sliding of the movable pulley on the trolley relative to the fixed pulley to open the switch valve to connect the paint box and the marking pipe, so that the paint flows out and marks the curved track to detect the same The two curved tracks have the advantage of reducing track detection errors.

Description

technical field [0001] The present application relates to the technical field of railway detection, and in particular, to an instrument for measuring the deformation and quality of railway tracks. Background technique [0002] At present, my country's road construction is becoming more and more comprehensive, and the increase in railways has enabled more areas to use 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 railway, so more The railway track supports the operation of high-speed trains. [0003] Under the long-term use of the railway track, the track will be slightly deformed, and the deformation will gradually increase in the long run. In order to detect the deformation of the track, equipment such as an infrared rangefinder is usually used to measure the distance of the opposite points on the two tracks 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
