Abstract
The utility model relates to a kind of rail measuring apparatus gauge displacement measuring and testing device.The crossbeam of rail measuring apparatus is the ruler measuring gauge, and meter wheel to when producing displacement, needs corresponding measuring mechanism to measure variable quantity perpendicular to rail.The utility model is connected with connecting box in beam-end by piston rod, connecting box is fixed wtih road wheel and meter wheel; Connecting box end winding support has gauge displacement measurement main scale, and adjacent, parallel with the secondary chi of the gauge displacement measurement being positioned at crossbeam.The utility model rail measuring apparatus meter wheel to be provided with relevant measuring equipment between crossbeam, achieve by the Measurement accuracy of meter wheel to gauge displacement, and in limited space not with road wheel structure generation Steric clashes, compact conformation is reasonable, measures accurately and reliably.
Description
Technical field
the utility model belongs to railroad survey technical field, is specifically related to a kind of rail measuring apparatus gauge displacement measuring and testing device.
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, the crossbeam of this instrument is the ruler measuring gauge, meter wheel perpendicular to rail to generation displacement time, need corresponding measuring mechanism to measure variable quantity, complete the comprehensive detection to orbital forcing.
Summary of the invention
The purpose of this utility model is to provide a kind of rail measuring apparatus gauge displacement measuring and testing device, and the meter wheel of matching track measuring instrument carries out Measurement accuracy to gauge displacement.
The technical scheme that the utility model adopts is:
A kind of rail measuring apparatus gauge displacement measuring and testing device, is characterized in that:
Be connected with connecting box in beam-end by piston rod, connecting box end face is connected to road wheel by road wheel wheel shaft, and connecting box underrun meter wheel wheel shaft is connected to meter wheel;
Connecting box bottom surface be provided with near the end of crossbeam perpendicular to rail to connecting box chi groove, relative beam-end bottom surface is provided with the crossbeam chi groove with connecting box chi groove conllinear, connecting box chi groove is fixed in gauge displacement measurement main scale one end, and the other end slides in crossbeam chi groove; The groove of crossbeam chi groove is along being above provided with the secondary chi of the gauge displacement measurement parallel with gauge displacement measurement main scale.
The additional cover of piston rod has telescopic piston rod cover.
The utility model has the following advantages:
The utility model rail measuring apparatus meter wheel to be provided with relevant measuring equipment between crossbeam, achieve by the Measurement accuracy of meter wheel to gauge displacement, and in limited space not with road wheel structure generation Steric clashes, compact conformation is reasonable, in limited space, rational layout and tissue are carried out to assembly, achieve multi-functional integrated in the confined space, measure accurately and reliably.
