Abstract

The invention discloses a ballastless track settlement monitoring device. The ballastless track settlement monitoring device comprises guide rails, a fixing plate fixedly mounted at the front ends of the guide rails, a main plate fixedly mounted in the middles of the guide rails, and a mirror bracket movably mounted at the back ends of the guide rails and being capable of sliding along the axes of the guide rails, wherein a photodetector is arranged on the fixing plate; a laser, a light splitter and a first reflector are arranged on the main plate; a second reflector is arranged on the mirror bracket; the laser, the light splitter, the first reflector, the second reflector and the photodetector form a michelson interferometer; the mirror bracket is connected with a flanged settlement plate through a connecting post. The ballastless track settlement monitoring device measures settlement of a ballastless track in real time through the michelson interferometer, can measure micro-sized or even nano-sized settlement distance, and achieves the purposes of accurately perceiving settlement and monitoring the settlement amount.

Description

technical field [0001] The invention belongs to the technical field of settlement detection of ballastless track of high-speed railway, and in particular relates to a settlement monitoring device of ballastless track. Background technique [0002] With the development of China's railway technology, my country's railway traffic has gradually entered the era of high-speed rail. It is estimated that by 2020, through the construction of high-speed railways and passenger dedicated lines, the development of intercity passenger rail transit and the speed-up reconstruction of existing lines, China Railway will initially form a rapid passenger transport network with high-speed railways and passenger dedicated lines as the backbone, connecting major large and medium-sized cities across the country. [0003] Due to its high speed, high-speed railways require high ride comfort and high stability for the track structure. The traditional ballast track is not conducive to the improvement ...
