Embodiment Construction
[0040] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.
[0041] The specific process of an integrated real-time measurement method for longitudinal crawling and close-fitting gaps of tongue rails is as follows: figure 1 shown.
[0042] (1) if figure 2 , Figure 5 , Image 6 with Figure 7 As shown, the switch rail 1 is located inside the basic rail 25, and the switch machine pushes the switch rail 1 to move, keeping the switch rail 1 on one side and the basic rail 25 on the same side in a close contact state, and the switch rail 1 on the other side and the basic rail on the same side 25 is in the repelling state, and two groups of measuring devices are installed on the same section of the turnout rail (each turnout has a point rail respectively on the inboard of two basic rails, and all needs to be monitored). The first is the installation of the displaceme...

The invention belongs to the technical field of displacement measurement, and relates to an integrated real-time measurement method for longitudinal crawling and tight fit clearance of a switch rail.The method comprises the following steps that firstly, a displacement conversion transmission mechanism in a measuring device is installed on the switch rail, and a sealing box is arranged on ground;then initial data is measured through two sets of target mirrors, a laser displacement sensor and a sensor of a measuring device; the longitudinal crawling and the transverse sealing clearance of theswitch rail are worked out through initial data and linear displacement and angle displacement measured by movement of each point of the switch rail. According to the integrated real-time measurementmethod, the problem of simultaneous measurement difficulty of orthogonal displacement, namely the longitudinal crawling and the transverse closing clearance of the switch rail is solved, and simultaneous monitoring of crawling and sealing is realized.
Description
technical field [0001] The invention belongs to the technical field of displacement measurement, and relates to an integrated real-time measurement method for longitudinal crawling of a point rail and close-fitting gap. Background technique [0002] In the operation of high-speed railways, turnouts are the key equipment that constitutes the railway track, and turnouts have the characteristics of large number, complex structure, limited train speed, low driving safety, and large maintenance and repair investment. They are a major weak link of the track. Turnout point rails directly affect train speed and safety. Crawling of the switch and non-tight contact are the main problems of the turnout. Crawling of the switch will push the limiter to death, seriously causing bad direction of the top-bent basic rail and affecting the turning of the switch. The lack of close contact between the point rail and the basic rail may cause the train wheel pair to impact the point rail and the...
