Description

Railway track geometric state detection device

Technical Field

The utility model relates to a orbital ride comfort detects technical field, concretely relates to railway rails geometric state detection device.

Background

As the speed of train operation increases, the requirements for the geometry of the railroad track also increase. In order to ensure the running safety of freight trains and the running comfort of passenger trains, the geometric irregularity of the long tracks which is not obvious in the interaction between the wheel rails of the trains is gradually shown along with the increase of the running speed of the trains. The rail irregularity is an external interference to a train vehicle system and is a main source of vibration and even derailment of a vehicle running part. And the poor smoothness of track still can make train wheel rail contact surface receive stronger impact force, and the wearing and tearing and the destruction of wheel rail are accelerated, cause potential threat to driving safety.

The existing railway track smoothness detection device is established on the basis of a CP III control point during measurement, and converted into indirect measurement of linear deviation through angle and distance measurement of a total station. The CP III control points are designed on two sides of the railway at the beginning of railway construction at intervals of about 60 meters, forced centering marks are arranged on the CP III control points, and the CP III control points are known coordinate points. During detection, a prism is arranged on the CP III control point, then a total station is erected on the track, coordinates of the total station erection station are determined by observing coordinates of the known CP III control point, then the prisms on the track inspection vehicle are observed one by one on the sleepers, the center line coordinates are measured, and further track smoothness parameters are calculated.

The precision of the CP III control point can influence the detection precision, so a railway operation and maintenance party must regularly spend a large amount of expense on the precision retest of the CP III control point, and the detection speed is slow and the efficiency is low because the technology adopts the detection one by one sleeper, and one operation group and one 'skylight point' (4h) can only detect a 300m line at most. In addition, due to the extreme sensitivity of the total station to environmental conditions, the track geometry measuring instrument (hereinafter referred to as a track measuring instrument) is extremely susceptible to external environments such as temperature, humidity, light, visibility and wind speed during measurement, so that the accuracy of the measured coordinate values can meet the line position measurement requirement (plus or minus 10mm), but cannot meet the requirements of track medium and short wave smoothness (less than or equal to 2 mm). And the elevation measurement precision of the total station is very low, and the measurement result is unstable. Therefore, the currently adopted orbit measurement method is difficult to meet the measurement requirements on the smoothness of the short wave in the orbit during operation.
