Description
Technical field
The utility model belongs to rail checkout equipment technical field, relates in particular to a kind of rail connector defect inspectionSurvey device.
Background technology
The present situation of China railways track is: jointed track is many, rail is second-rate, bus routes is large, wagon flowDensity is large, rail damage is fast.
Rail connector comprises fastener and fish platee. Fastener is exactly for connecting rail and sleeper on trackPart, has another name called for middle union piece. Its effect is that rail is fixed on sleeper, keeps the constant of gaugeWith the vertical and horizontal motion of rail with respect to sleeper. It is the vitals that ensures train operation. Railway rail clipInefficacy Train Dynamic derailing is had to very large impact.
For fear of expanding with heat and contract with cold, equally also, in order to reduce vibration influence, the way of traditional railway is 20The rail that rice left and right is one section is fixed on sleeper, between each section of rail, has joint. What this used in conjunction with joint isFish platee (connector), it is the steel plate of approximately 60 centimeter length, there are four or six mouthfuls of steel bolts at two ends, useBe buckled on the duck eye on rail. In train vibration influence process, that crash when crash the sound of working as, that is vacillating and staggeringSensation, be all that wheel clashes into while crossing the gap in the middle of rail and produces. Rail joint is thin on trackWeak link, when train by time, because the power of withstanding shocks is subject to very large strike, also track just of fish plateeIn hold flimsy easily-consumed products most, steel bolt comes off, fish platee is loosening is all common sympton.
Recall history, only on Europe, the disastrous accident more than causing because fish platee goes wrongInferior. Before 2002, be because fish platee gets loose equally, Britain's train the baud of outskirts of london thisBar is overstepped the limit and is overturned, and causes six passengers and passerby's death on car. In July, 2013, just on French National DayIn the evening peak time at vacation eve, one leave for from Paris Li Mo Japanese side to train carry 385 passengers,Because the loss of fish platee is out of control suddenly when by way of mine-laying base of a fruit Buddhist nun, train seven saves the joint derailing of four in compartment,Speed with 85 miles per hours has knocked crowded railway platform ruthlessly.
Rail welding point hurt rail and connector defect are the one of the main reasons that railway accident takes place frequently. IronThe defect of rail and connecting piece has a strong impact on stationarity, the security in locomotive operation. So should be timely to ironThe defect of rail and connecting piece detects, and ensures the normal operation of train. For the detection of rail, on average everyYear, every wireline inspection needed more than ten times, always detect the nearly gigameter of mileage. And be mainly to rely on people at presentWork detects, and such workload is very huge, and efficiency is low.
Machine vision technique is an integrated technology, comprise vision sensor technology, light illumination technology,Optical image technology, digital image processing techniques, computer hardware technique, analog digital switch technology andAutomatic control technologys etc. have related to multiple subjects. It is very difficult providing a precise definition, at presentThe definition that US Manufacturing Industry IEEE provides is: machine vision is that use equipment carries out noncontact light perception,Automatic acquisition and release the image of a real scene, is used for obtaining information and control the process of machine. Simultaneously largePart expert also recognizes same more vivid explanation: machine vision is to replace human eye to carry out target pair with machineIdentification, judgement and the measurement of elephant, the visual performance of research computer simulation human eye.
So, in conjunction with robot vision technology, research and develop untouchablely, detect efficiently rail connecting piece defectDevice be very necessary, the trend of the times of Zhe Yeshi China development.
