Abstract

The invention discloses a track geometrical state high-accuracy measurement device which comprises a main vehicle frame. The main vehicle frame is provided with a walking mechanism, a measurement mechanism, a sensing mechanism and a main control unit. The walking mechanism comprises a first walking wheel, a second walking wheel, a third walking wheel, a first guide wheel and a second guide wheel.The measurement mechanism comprises a prism arranged on the main vehicle frame and a measurement wheel arranged corresponding to the first walking wheel. The sensing mechanism comprises a gauge sensorand tilt angle sensors which are arranged in the main vehicle frame. By the adoption of the track geometrical state high-accuracy measurement device, data of the gauge and the superelevation of a track can be measured in real time, three-dimensional coordinate data of the prism are measured through a total station, the measured data are processed through the main control unit to obtain track geometrical state indexes such as the track direction, the height, the versed sine and the distortion of the track, deviation between a track plane and a design value and deviation between the elevation and a design value, the measurement accuracy of the device is greatly improved, and the accuracy and reliability of a measurement result are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of track detection, and more specifically relates to a high-precision measuring device for the geometric state of a track. Background technique [0002] In recent years, China's high-speed railway has developed rapidly. High-speed railway has the characteristics of high speed, high safety and high comfort, all of which are inseparable from the high ride comfort of its track. Therefore, how to ensure the high smoothness of the track, that is, how to efficiently, stably and reliably detect the internal and external geometric forms of the track, and adjust the smoothness and spatial position of the track to meet the design requirements, is the key to the construction of high-speed railway track engineering. One of the key technologies. The main technical indicators for evaluating track smoothness include relative smoothness indicators such as gauge, superelevation (horizontal), rail direction, height, positive...
