Smoothly transporting passengers and goods, and steadily, safely guide the travel direction of train.But in being runed with urban track traffic
Journey is continuously increased and the high speed of train, heavy duty, high density operation, repeated action and natural cause of the track in train load
Under the influence of, elastic deformation can be not only produced, and be often permanently deformed, track geometry deviation is formed, also known as track not
Smooth-going.Track irregularity is the excitation source of wheel rail system, is the main original for causing train to produce vibration and dynamic action between wheel and rail power
Cause, will produce material impact to traffic safety, steady, comfortableness.Therefore, to ensure the kilter of track, it is necessary to strengthen rail
The dynamic detection in road, grasps track quality state, accurate instruction track maintenance and repair, to ensure city rail transport peace in time
Entirely.And at present the country track traffic track detecting still based on track checking car, detection technique is not perfect, restricts to a certain extent
The precision and reliability of detection, the need for people far can not have been met to train safety and comfortableness.
Utility model content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model be to provide one kind can dynamic detection and detection
The detection means for double track flatness of high precision.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of detection means for double track flatness, including across the support between two tracks and be separately positioned on
The Liang Ge testing agencies at support two ends, the two ends of the support are equipped with directive wheel, and the support is slided by directive wheel with track
Dynamic connection, the testing agency include crossbeam, be respectively fixedly connected with crossbeam both sides two support arms and be separately fixed at two
Two image acquisition devices on arm, the two support arms difference is outward-dipping so that be fixedly mounted on two images on two support arms
The detection line of collector is in 120 degree of angles.
A kind of embodiment, directive wheel fixed mount and directive wheel, the directive wheel are symmetrically arranged on two with what support was often held
It is slidably connected with respective rail.
Preferably, two image acquisition devices of each testing agency are symmetricly set on the two of each track in opposite directions
