Online Detecting Technology of Turnout Rail Milling Accuracy

Using non-contact detection technology,the rail section was scanned by means of sensors distributed on both sides of the measured rail.Data acquisition and analysis were carried out by computer processing software,the final results were compared with the design values,and rail milling accuracy was evaluated.Using digital processing technology,the data exchange between the detection system and the computer number control center of the mobile boring and milling machine was realized by the protocol conversion module,the accurate position of the milling outf it was obtained in real time.The transverse and vertical adjustment of the measuring device was realized by adopting the transmission mechanism with compact mechanical structure,convenient assembling and maintaining,which guaranteed the non-interference between on-line detection system and milling tooling.Through digital processing and integration technology,automatic detection and fine management of turnout rail section size are realized.
