Abstract
The invention relates to a parallel connection structure for track measurement instrument measuring wheels and displacement sensors. The accuracy and reliability of data collection are directly influenced by the spatial arrangement of the track measurement instrument measuring wheels and the displacement sensors. The parallel connection structure comprises a measuring wheel and a displacement sensor, wherein an installation base plate which is provided with an upward opening and shaped like a Chinese character 'ji' is arranged on the bottom face of one end of a beam, a guide track perpendicular to the track direction is arranged on the bottom face of the installation base plate, a guide track slide block is arranged in the guide track, the measuring wheel is fixed to the bottom face of the guide track slide block through a measuring wheel axle, the displacement sensor is arranged in a groove in the installation base plate shaped like the Chinese character 'ji', and the displacement sensor is connected with the guide track slide block through an L-shaped connection plate. The measuring wheel is fixed to the slide block of the guide track, the slide block and the displacement sensor are installed on the upper side and the lower side of the installation base plate respectively, and therefore the vertically-distributed parallel connection relation is achieved, the reasonable layout of the measuring wheel and the displacement sensor on the aspect of spatial positions is achieved, and the compactness of a beam arrangement structure is improved.
Description
Technical field
the invention belongs to railroad survey technical field, be specifically related to the parallel connecting structure 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
