The invention belongs to the technical field of track safety, and particularly provides a high-speed railway ballastless track steel rail telescopic regulator monitoring system and method. Relative displacement of the sharp end of a switch rail and a stock rail, relative displacement of the root end of the stock rail and the switch rail, tight attachment condition of the switch rail and the stockrail, the bridge beam seam expansion amount, the steel rail top surface light band state and the rail lifting inclination condition are acquired in real time through an image acquisition module and displayed through the background terminal; and the temperature of the steel rail is acquired through a temperature acquisition module and displayed through the background terminal. According to the scheme, non-contact measurement of the displacement and the temperature of the track structure of the ballastless track steel rail telescopic regulator section is realized, and the service state of the track is automatically reflected in real time, so that normal use of the ballastless track steel rail telescopic regulator and the track lifting device is ensured, safe operation and maintenance of a line are ensured, and better commercial popularization and application prospects are realized.
Description
technical field [0001] The invention belongs to the technical field of track safety, and in particular relates to a monitoring system and method for a telescopic regulator of a ballastless track rail of a high-speed railway. Background technique [0002] With the full development of the construction of passenger dedicated lines in our country, the proportion of bridges is increasing. When laying seamless lines on long-span bridges, the beam-rail interaction caused by bridge expansion and contraction will intensify, and the rails will bear huge additional forces, which exceed the allowable stress of the rails. At the same time, the bridge and the rails will also produce large relative displacements that affect the line. Therefore, for seamless lines on long-span bridges, rail telescopic regulators must be considered. [0003] Ballastless track has the advantages of high smoothness, high stability, durability and less maintenance, and is welcomed by operation and maintenance ...
