Description
Technical field
This utility model relates to a kind of static railroad track assembly overall size and disease Systems for optical inspection, a kind of Systems for optical inspection that the railroad track component states under its resting state deformed can not be made to carry out complete detection in added load railroad track assembly more precisely.Relative with static railway detection is be loaded with such as passenger and freight train, railcar and track detection vehicle etc. on the railroad track to be sufficient for the dynamic detection of railroad track component strain.
Background technology
Running on railway, no matter it is because the wheel spin promptly accelerating to cause of running train, also be because brake hard slow down cause wheel lock up aggravation rail surface corrugation, fall block, or the rail head of rail heel and toe wear that causes of the properly functioning and corrugation that produces at rail head, fat edges (overlap), the reason such as tread or rail break, and the steel rail base slope disease such as exceed standard is both needed to detect.
When rail abrasion face is measured by the measurement of rail wear based instrument adopting special development, no matter it is adopt contact-type measurement of rail wear based instrument gauge head or adopt the range laser of laser ranging shaped steel rail abrasion measuring instrument, it it is all the vertical and lateral coordinate figure gathering rail abrasion face same point, draw the curve in rail abrasion face, contrast with the rail surface of standard again, calculating the wear extent of rail head of rail, this detection process required time is not less than 120 seconds.
nullWhen adopting rail level corrugation measuring instrument that rail rail level corrugation is measured，No matter it is adopt contact-type rail level corrugation measuring instrument or adopt laser ranging type rail level corrugation measuring instrument，It is all that rail level corrugation measuring instrument is placed on rail surface along line direction，Move the range finding gauge head being installed on rail level corrugation measuring instrument gauge head guide rail again and gather the rail surface coordinate figure along the rail surface of line direction，Detecting that (measurement of general rail level corrugation measuring instrument ranges for 1 meter to rail level corrugation measuring instrument measurement length range，This detection process is typically necessary 120 seconds) rail surface coordinate figure after，Fair line road is moved rail level corrugation measuring instrument and is measured the half of extent length (because needing the scope of the rail surface corrugation amount of detection often to exceed 1 meter to it，Therefore need to the measurement scope of adjacent twice be overlapped a part of，General displacement is all 0.5 meter)，It is again started up rail level corrugation measuring instrument，Detect that the coordinate figure of the rail surface of length range measured by rail level corrugation measuring instrument，So repeat，The rail level corrugation amount of last resynthesis certain length.
Because two strands of rail of railway are in operation the inclination angle that must keep to the road heart, tapering to ensure train wheel overlaps with rail surface, to reduce the abrasion of rail head of rail, a centripetal force can also be provided to train wheel simultaneously, ensure safe train operation, therefore must detect by tracking bottom sloping.When adopting the internally installed rail cant measuring instrument having obliquity sensor that the gradient of rail foot surface is detected, first have to that the sleeper slope of rail cant measuring instrument is detected datum level and be placed on sleeper, measure the level inclination of sleeper, the flange of rail slope detection datum level of rail cant measuring instrument is stuck in the flange of rail face of rail again, measure the level inclination of current rail foot, the difference of two angle values is the rail cant value angle value of current rail, therefore the flange of rail gradient of same sleeper both sides rail, therefore the rail cant of same place both sides rail is measured and need to be carried out three angle of bank measurement, and the calculating performed twice at can obtain, one-shot measurement is consuming time is not less than about 60 seconds, detection efficiency is low.
At present to because the rail fastening combination nut that the vibration of train operation causes loosens or the detection that comes off at present and to concrete sleeper, the crackle of non-fragment orbit concrete slab sleeper and falls block or equivalent damage is then adopt the artificial mode estimating hand-kept to implement, detection efficiency is low, it would be highly desirable to improve！
