Along with the occurrence of faults in daily railway management, safe and high-quality travel is realized, red lines are mostly adopted on railways for measurement, and the standard railway lines are also called red lines, are marked on the inner edges of contact net struts or on side walls of tunnels, bridges and platforms and are used for representing the standard height of the top surface of a steel rail in operation. At present, two modes are adopted for measuring and marking the red line on the rail surface at home and abroad, the first mode is the traditional mode, namely, a horizontal T-square is utilized, one side of the T-square is lapped on a steel rail, the other side of the T-square is leaned against a support column, the side limiting distance can be measured, the red line position can be measured through up-down horizontal adjustment, the T-square is lapped on a high rail to be adjusted horizontally when encountering a curve, the distance between the T-square and a low rail (also called as super high), and then 1/2 of the super high position extends to the horizontal position of the support column to determine the red line position. The second mode is to use a special laser measuring instrument to measure each strut, put the measuring instrument on two steel rails, laser the measuring instrument to the struts, intelligently obtain ultra-high and side limit data by the measuring instrument, and mark red lines. The two methods have the advantages of large manpower consumption and large data measurement error.
Along with the gradual rise of the freight traffic and the passenger traffic of rail transit, the maintenance and overhaul of railway traffic operation are increasingly emphasized, and the requirements on the accurate measurement and positioning work of the red line of the railway rail surface are higher. The switch serving as the track line change and conversion equipment is the key link with the highest requirement on the track condition and the most complicated in the technical index of the working line, the reliability of the switch is the important direction in the railway transportation operation and maintenance process, and the accurate detection data cannot be obtained due to the fact that the detection trolley cannot be tightly attached to the steel rail in the process of driving through the switch. However, at present, the inspection of the turnout mainly depends on manual detection and measurement, so that certain potential safety hazard exists when the train runs more densely.
Therefore, in order to realize accurate positioning on the steel rail, a rail surface red line measuring and jacking device is urgently needed to solve a plurality of problems.
