Serial connection structure for track measurement instrument measuring wheels and displacement sensors

Abstract

The invention relates to a serial connection structure for track measurement instrument measuring wheels and displacement sensors. The measuring wheels are arranged on the inner sides of walking wheels at the two ends of a track measurement instrument beam respectively, the accuracy and reliability of data collection are directly influenced by the spatial layout of the measuring wheels and the displacement sensors, and the compactness and reasonability of the whole beam are influenced. A guide track perpendicular to the track direction is arranged on the bottom face of the end of the beam, a track groove faces downwards, a guide track slide block is arranged in the guide track, the corresponding measuring wheel is fixed to the bottom of the outer end of the guide track slide block, and the inner end of the guide track slide block is connected with the corresponding displacement sensor through a connection plate. The corresponding measuring wheel is fixed to the slide block of the guide rail, the slide block and the corresponding displacement sensor are connected in series in the beam direction, the reasonable layout of the corresponding measuring wheel and the corresponding displacement sensor is achieved on the aspect of spatial positions, the compactness of a beam arrangement structure is improved, and the accuracy and reliability of the measuring result of the corresponding displacement sensor are ensured.

Description

technical field [0001] The invention belongs to the technical field of railway measurement, and in particular relates to a serial connection structure of a measuring wheel of a rail measuring instrument and a displacement sensor. 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 imp...

AI Technical Summary

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. Measuring wheels are installed on the inner side of the running wheels at both ends of the instrument beam to measure the gauge or track vector distance. The displacement perpendicular to the rail direction must be obtained by displacement sensors. The spatial layout of the measuring wheel and displacement sensors directly affects the accuracy and reliability of data collection, and also affects the compactness and rationality of the overall beam structure.
