Track slab precision adjustment measurement system and adjusting measuring method

Abstract

The present invention provides one kind of precise rail board regulating and measuring system for installing and locating rail board in high speed railway in high precision. The precise rail board regulating and measuring system includes a measuring robot, measurement controlling equipment, a regulating amount display terminal, a precise micro prism, a precise measuring frame and a precisely centering tripod. The measurement controlling equipment includes an industrial control computer, a data transmitting station connected to the industrial control computer, and a data transmitting station connected to the measuring robot. The present invention has high precision of measurement, installation and location, and is especially suitable for precise regulating operation of rail board in high speed railway.

Description

technical field [0001] The invention relates to a precise measurement and positioning device for installing track slabs during high-speed railway construction, in particular to a high-speed railway track slab precision adjustment system and an adjustment and measurement method thereof. Background technique [0002] Railways that can carry trains at a speed of more than 300 kilometers per hour are called high-speed railways, including intercity rail transit, passenger dedicated lines, mixed passenger and freight lines, and freight dedicated lines, etc. Neither the bearing capacity nor smoothness of traditional ballasted tracks can guarantee the safe running of high-speed trains. The slab ballastless track is a track structure with less maintenance. It uses formed composite materials instead of ballast to distribute and transfer the wheel-rail force to the subgrade foundation. Slab ballastless track is generally composed of basic antifreeze layer, support layer, waterproof an...

Problems solved by technology

[0003] The existing measurement and positioning method is to use a high-precision measurement robot to manually input the coordinates to be measured into the instrument. In order to improve the measurement accuracy, it is also necessary to build cement observation piers on the control points on both sides of the railway to place the measurement robot for alignment. Leveling, even so, the height of the measuring robot is still not a fixed value, because the measuring robot needs to be leveled by the three adjustment screws on its own base before each measurement. Every time the measuring robot is moved, its leveling It is difficult to keep the same height

In addition, the current measuring prism is set up on the point to be measured with a wooden tripod, and then the height of the prism is measured with a steel tape. All links require manual intervention, which not only increases the chance of error, but also reduces production efficiency.

Therefore, existing measurement and positioning equipment and methods cannot meet such high-precision requirements at all.
