The invention is a portable push-type railway track detection vehicle, which is used to detect the geometric parameters of the rail such as: gauge, superelevation, and triangular pit, including mechanical structure, power supply, induction test, control and display parts, and the mechanical structure is "I" shaped structure, three-point frame. The hollow main girder of the two rails of the horizontal frame is equipped with a supporting traveling mechanism, a tight mechanism, a hand-held push rod, a measuring mechanism, a control system, a power supply, a display box and various sensors. The three rollers and their mechanisms are both supporting and walking mechanism. One side of the abutting mechanism is a positioning roller, and the other side is a retractable pressing roller, so that the main beam is perpendicular to the track and close to the inner side of the rail. The invention not only solves the problems of convenient use, light weight, stable operation, small vibration and corrosion resistance, but also provides a new device for realizing dynamic continuous measurement, high measurement accuracy, good rigidity, and stable reference plane. The structure is light and simple, The concept is novel, the operation is convenient, and it can be put into industrial application quickly.
