High-speed Railway Track Spatial Position Measuring Instrument with Straightedge Suspension Structure

Abstract

The invention relates to a high-speed railway track space position measuring instrument with a straightedge suspension structure. At present, most of the track measuring instruments used in the construction field are integral structures, which are not effective in horizontal and vertical positioning, and have a single function, which cannot accurately record subtle changes in the track. The present invention includes a measuring part and a running part; the measuring part includes a beam main body, a rail vector distance measuring and detecting device and a gauge displacement measuring and detecting device are respectively arranged at both ends, and a lateral self-adaptive positioning device is fixed in the middle of the bottom surface; the running part includes a beam The front and rear of one side of the upper cover are connected with a separate traveling wheel driving device; the beam main body of the measuring part is suspended from the walking part and the upper cover of the beam through the suspension shaft in the middle. In the invention, the structure of each part of the track measuring instrument is separately arranged and assembled on site, so as to improve the measurement accuracy and expand the measurement range.

Description

technical field [0001] The invention belongs to the technical field of railway measurement, and in particular relates to a high-speed railway track space position measuring instrument with a straightedge suspension structure. 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 impor...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection of railway track smoothness is mostly carried out by means of track geometric state measuring instruments, that is, track measuring instruments. However, most of the track measuring instruments used in the field of construction are integral structures, and the effect of horizontal and vertical positioning is not good. The function is also relatively single, and it is impossible to accurately record subtle changes in the track
