Quick geometrical state measuring instrument for track
The invention discloses a quick geometrical state measuring instrument for a track. The quick geometrical state measuring instrument for the track comprises a hand-propelled track inspection trolley, an inertial navigation system, an inclination angle sensor, a linear displacement sensor, a speed and mileage sensor, an intelligent total station and a data acquisition controller, wherein a main body of the quick geometrical state measuring instrument for the track is the hand-propelled track inspection trolley which can walk along the track; sensors for detecting a speed, mileage, a track space, an inclination angle and the like, the inertial navigation system, the intelligent total station and the data acquisition controller are integrated on the hand-propelled track inspection trolley. The quick geometrical state measuring instrument for the track is based on the principle of combining absolute measurement with relative measurement, the geometrical ride comfort evaluation parameters, such as the mileage, the track space, the levelness, the twist warp, the track direction and the height of the track, and the absolute deviations of the plane and the elevation of the track can be detected in real time. By using the quick geometrical state measuring instrument for the track, the detection of the parameters of the track is realized through the inertial navigation system; the absolute constraint is carried out through the intelligent total station; the quick geometrical state measuring instrument for the track is high in precision and quick in speed, and is influenced less by an external environment.
