Transverse and vertical dynamic displacement measuring device of high-speed railway track circuit

Abstract

The invention belongs to a railway transportation field and relates to a device for measuring horizontally and vertically dynamic displacement of a high-speed railway track line. The device comprises two baffle boards which are equipped at middle of the measured rail perpendicular to the ground or form an angle of 45 degrees with the ground, two laser displacement sensors, and a portable data processing and displaying device; making use of the baffle board which forms an angle of 45 degrees with the ground, the vertical displacement of the track line is converted into a change amount of a horizontal distance by a proportion of 1:1 equivalently; heads of the two laser displacement sensors are aligned with the two baffle boards to measure the dynamic horizontal displacement and the compound displacement including the horizontal displacement and the vertical displacement when a high-speed train passes; the data measured by the two laser displacement sensors are processed by the portable data processing and displaying device, and then the instantaneous horizontal and vertical displacement during the high-speed train passing the track line can be read directly; The measuring device has the advantages of accurate measured data and high respond speed.

Description

technical field [0001] The invention belongs to the field of railway transportation, and relates to a device for measuring lateral and vertical dynamic displacements of high-speed railway track lines. technical background [0002] On April 18, 2007, with the successful implementation of the sixth large-scale speed increase as an important symbol, my country's railways opened the prelude to the high-speed era. With the development of the national economy, higher and higher requirements are put forward for railway transportation. EMUs with a running speed of 200km / h-350km / h have appeared between Shanghai, Beijing, Shanghai, Nanjing, Shanghai, Suzhou and other regions. Trains have brought great convenience to the travel of passengers. However, some problems followed. EMUs and high-speed trains swayed obviously in some line sections, which reduced the travel comfort of high-speed railways and high-speed railway passenger trains, and also brought certain safety hazards. After r...

Problems solved by technology

However, due to the large detection error of the "car shaking detector", the specific location cannot be accurately reported, only the approximate location can be reported, and it is still impossible to measure the over-limit deviation of the dynamic lateral and vertical displacement
