The present invention arrange in beam-end bottom surface be perpendicular to rail to guide rail, rail groove is downward, is provided with guide rail slide block in guide rail, fixation measuring wheel bottom guide rail slide block outer end, and guide rail slide block the inner is connected with displacement sensor by web plate. Measuring wheel is fixed on the slide block of guide rail by the present invention, again by slide block and displacement sensor on crossbeam direction connected in series, achieve measuring wheel and the displacement sensor rational deployment on locus, improve the compactness that crossbeam arranges structure, ensure that the accuracy of displacement sensor result and reliability.
Description
Technical field
The invention belongs to railway field of measuring technique, it is specifically related to the structure connected in series of a kind of rail measuring apparatus measuring wheel and displacement sensor.
Background technology
The smooth degree of railroad track refers to that the height that track is occurred rises and falls and left and right skew, affects the normal traveling of train owing to train runs the change with track bed for a long time in orbit. Along with improving constantly of train running speed, for realizing the security of train operation and comfortable property, particularly the ride comfort of high speed railway track directly affects the safety and steadily of bullet train, the design and construction of circuit must accomplish high ride, railway irregularity state parameter is required more and more higher by railway, therefore with safeguarding, the detection of rail smooth degree is particularly seemed important.
At present, mode for detection many employings track geometry status survey meter of railroad track smooth degree carries out, i.e. rail measuring apparatus, the walking wheel inner side at these instrument crossbeam two ends is provided with measuring wheel, measurement gauge or rail are to vector distance, measuring wheel be perpendicular to rail to displacement to be obtained by displacement sensor, the space layout of measuring wheel and displacement sensor directly affects accuracy and the reliability of data gathering, also have impact on the compactness of Integral cross beam structure and reasonableness.
