Track geometric parameter measuring instrument using double-galvanometer laser scanning module

Abstract

The invention discloses a track geometric parameter measuring instrument using a double-galvanometer laser scanning module, which is mounted on a movable track inspection trolley and is internally provided with a data acquisition control panel. The data acquisition control panel is connected with the angle sensor, the linear displacement sensor, the mileage sensor and the double-galvanometer laser scanning module. Sensors for detecting mileage, track gauge, angle and the like, a double-galvanometer laser scanning module and a data acquisition control panel are integrated on the hand-push type track detection trolley. Based on the principle of relative measurement, the track geometric parameter measuring instrument can detect track geometric smoothness evaluation parameters such as mileage, track gauge, levelness (superelevation), triangular pit, track direction and height of a track in real time, the track geometric parameter measuring instrument uses the double-galvanometer laser scanning module to measure relative position coordinates, the measuring precision is high, and the measuring speed is high.

Description

technical field [0001] The invention relates to a track geometric parameter measuring instrument, in particular to a track geometric parameter measuring instrument using a double vibrating mirror laser scanning module. Background technique [0002] With the rapid development of my country's economy and the rapid advancement of rail transit construction, the pressure on the rail transit system is increasing, and the traffic density is also increasing. The speed requirements for measuring various geometric parameters of the track are also getting higher and higher. . [0003] However, the track geometric parameter measuring instrument of the prior art uses a total station for absolute position positioning, and the existing problems mainly include: [0004] 1. The track inspection trolley needs to communicate with the total station, and the control method is complicated; [0005] 2. The low-cost manual total station relies on manual focusing, and the measurement speed is slow....

Problems solved by technology

[0004] 1. The track inspection trolley needs to communicate with the total station, and the control method is complicated;

[0005] 2. The low-cost manual total station relies on manual focus, and the measurement speed is slow

The automatic total station uses a servo motor to drive the heavy lens platform to move to find the target, and the moving speed is also slow and the cost is high;

[0006] 3. The total station is bulky and heavy

[0007] There is still no effective technical means to solve the above problems in the prior art, which can no longer meet people's requirements
