Embodiment Construction

[0015] The present invention uses structured light technology to detect the geometric parameters of the contact rail. The detection device includes four 2D laser sensors, and the four 2D laser sensors are installed on the same steel frame, and the relative positions between the two sets of sensors are fixed.

[0016] Among them, two 2D laser sensors irradiate the outer side and top surface of the contact rails on both sides respectively, and are used to measure the relative distance between the left and right contact rails and the detection device, combined with the gauge measured by the other two 2D laser sensors (cross-section The distance between the outermost points in the horizontal direction) and the relative distance between the F rail and the laser sensor, as well as the distance between the two groups of sensors, transform the contact rail detection data with the detection device as the reference system into the track center coordinate system, Calculate derailment offs...

Abstract

The invention discloses a dynamic medium/low-speed maglev line current-feeding contact rail detection device and method. The detection device comprises four laser sensors mounted on the same rigid framework, wherein the first laser sensor and the third laser sensor respectively irradiate the outer side face and top surface of contact rails on the left and right sides; the second laser sensor and the fourth laser sensor are used for measuring the track gauge of the F rails and the relative distance between the F rails and the two laser sensors. The detection device disclosed by the invention is high in measurement accuracy, small in errors, capable of realizing continuous tests and high in real-time property.

Description

technical field [0001] The invention relates to track measurement and detection of a medium and low speed maglev line, in particular to a dynamic detection device and method for a current receiving contact rail of a medium and low speed maglev line. Background technique [0002] The track of medium and low-speed maglev trains mainly includes rail row, current contact rail and concrete support. After the maglev line track is installed and in the later daily maintenance, it is necessary to inspect and measure the track frequently to check whether the track parameters meet the design requirements. Require. The special cross-sectional shape of the F-shaped rail of the medium and low-speed maglev train is different from the traditional wheel-rail "I"-shaped track. Parameter measurement. [0003] The vertical installation height and horizontal installation width of the contact rail of medium and low speed maglev trains will directly affect the current receiving function of the t...
