Abstract

The invention relates to a steel rail milling and grinding machine operation accuracy real-time detecting device. The device comprises a steel rail profile measuring system, an undulatory wear measuring system, a mileage measuring unit, and a data processing and displaying system, wherein the steel rail profile measuring system, wherein the wave wear measurement system, the undulatory wear measuring system, the mileage measuring unit are respectively connected with the data processing and displaying system. The device can quickly detect operation accuracy of a steel rail milling and grinding machine in real time, detection labor intensity is reduced, and e the efficiency of railway track maintenance is improved.

Description

Technical field [0001] The invention relates to a railway rail measuring device, in particular to a device for real-time detection of the working precision of rail milling and grinding vehicles. Background technique [0002] With the development of high-speed railways, it is increasingly important to focus on the prevention and repair of rail defects, and to study and improve rail profile control technology. Re-trimming the vertical and horizontal shape of the rail to eliminate defects on the rail surface such as wave wear and fat edges; reducing the error between the rail head profile and the given target profile, and restoring the normal rail head geometry; improving the running stability and comfort of the train, reducing The damage of the train to the subgrade bed, delaying the generation cycle of rail defects, prolonging the service life of rails, and reducing the maintenance costs of rolling stock and lines have obvious comprehensive benefits. [0003] At present, rai...
