Description
Technical Field
The invention belongs to the field of rail transit safety, and relates to an integrated real-time measuring device for longitudinal crawling and close contact clearance of switch rails.
Background
In the operation of a high-speed railway, turnouts are key equipment for forming railway tracks, and the turnouts have the characteristics of large quantity, complex structure, limitation on train speed, low traffic safety, high maintenance and repair investment and the like, and are a weak link of the tracks. The switch points therein directly affect the train operating speed and safety. The switch rail climbing and non-close contact are main faults of the turnout, the switch rail climbing amount refers to the longitudinal displacement of the turnout switch rail relative to the stock rail, the switch rail close contact amount refers to the gap between the switch rail and the stock rail at the connecting position of the switch machine and the switch rail, the outage event that the turnout has no open signal due to the climbing exceeding and non-close contact is reduced, and the turnout safe operation and the orderly operation of lines play an important role.
The invention discloses a method for monitoring the crawling amount of a switch point rail based on image recognition, which is characterized in that a camera, a scale and an additional light source are used in the method, and the maintenance is difficult in a severe environment. A KTC-75mm pull rod type linear displacement sensor is selected to monitor the crawling displacement of the steel rail in a Notification thesis on seamless steel rail crawling monitoring system design based on ZigBee technology of the university of China, and the Notification contact type displacement measurement can not be fixedly arranged beside the rail aiming at the fact that the switch-on and switch-off movement with a stock rail is required under the working state of a switch rail. Siemens cipher checker and JM1 cipher checker are commercial cipher check equipments, but only "on" and "off" signals are given to whether the point rail cipher is "in place", and the continuous change, variation range and frequency of the gap during the cipher cannot be reflected. At present, a device for integrated real-time continuous measurement of longitudinal crawling and close contact clearance of a switch rail is not available.
In conclusion, the conventional measuring device mainly measures parameters of the switch rail creeping and the close contact clearance independently, cannot comprehensively analyze the data variation, rule and trend of the switch rail creeping and the close contact clearance, and has the problems of installation interference and higher maintenance difficulty when measuring two displacement variations because the creeping displacement and the close contact displacement belong to orthogonal displacement.
