Rail Space Attitude Adaptive Positioning Structure of Rail Measuring Instrument

Abstract

The invention relates to an adaptive positioning structure for a rail space attitude of a rail measuring instrument. In the process of measuring the gauge of the track gauge, there is no practical calibration device to check the verticality of the rail direction of the beam. The present invention includes a guide chute with the notch facing down, and a sliding shaft is arranged inside; one end of the sliding shaft is fixed on the wheel support, the bottom surface is provided with a fixed plate for the movable end of the gas spring, and two rails are connected to both sides of the rail and are parallel to and perpendicular to the rail. The other end of the gas spring is fixed on the fixed end fixed plate of the gas spring, and the fixed end fixed plate of the gas spring is hinged with a transmission flap and a transmission plate in turn. One end is provided with a transmission handle. The invention has a reasonable structure, pushes the two ends of the beam to the track through the gas spring, makes the measuring wheel close to the inner side of the track, ensures that the beam of the track measuring instrument is always perpendicular to the track, and improves the reliability and accuracy of the track measuring instrument in measuring the gauge. accuracy.

Description

technical field [0001] The invention belongs to the technical field of railway measurement, and in particular relates to a rail space attitude self-adaptive positioning structure of a rail measuring instrument. Background technique [0002] The smoothness of the railway track refers to the ups and downs and left-right deviation of the track due to the long-term operation of the train on the track and the change of the track subgrade, which affects the normal running of the train. With the continuous improvement of train speed, in order to achieve the safety and comfort of train operation, especially the smoothness of high-speed railway tracks directly affects the safety and stability of high-speed trains, the design and construction of lines must achieve high smoothness, The railway department has higher and higher requirements on the parameters of the railway irregularity state, so the detection and maintenance of the track smoothness is particularly important.

Problems solved by technology

[0003] At present, the detection of railway track smoothness is mostly carried out by means of a track geometric state measuring instrument, that is, a track measuring instrument. In the process of measuring the gauge, the track measuring instrument must ensure that the direction of measuring the gauge is perpendicular to the longitudinal direction of the track. At present, There is no practical mechanical calibration device to check this vertical relationship, which affects the reliability and accuracy of the track measuring instrument during the measurement process
