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
the invention belongs to railroad survey technical field, be specifically related to the structure connected in series of a kind of rail measuring apparatus meter wheel and displacement transducer.
Background technology
The smooth degree of railroad track refers to that the height that track is occurred rises and falls and left and right offsets, and affects the normal traveling of train because train orbits and the change of track bed for a long time.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, particularly the ride comfort of high speed railway track directly affects the safety of bullet train with steady, the design and construction of circuit must accomplish high ride, railroad requires more and more higher to railway irregularity state parameter, therefore particularly seems important to the detection of rail smooth degree with maintenance.
At present, detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, i.e. rail measuring apparatus, meter wheel is provided with inside the road wheel at these instrument crossbeam two ends, measurement gauge or rail are to vector distance, meter wheel perpendicular to rail to displacement to be obtained by displacement transducer, the space layout of meter wheel and displacement transducer directly affects accuracy and the reliability of data acquisition, also have impact on compactness and the reasonability of Integral cross beam structure.
Summary of the invention
