The invention relates to the field of railway equipment railway roads, in particular to a method of alignment of the railway track in plan, longitudinal profile and level and device for its implementation, and can be used for preventive leveling path and finish way before commissioning after production major track work.

The efficiency and quality of the alignment path depend on the reliability and accuracy of the set of device parameters of a rail track and settlement shifts and podemos path, which in turn depend on the reliability and accuracy of the information about the actual position of the path on which they are calculated. Therefore, the improvement of measurement systems for the in-situ position of the railway track engineering and information support myprivacy management & bearing path currently is an important and urgent task.

There is a method of alignment of the railway track, which measure the position of the path relative to reference points in the points of their location, determine the position of the path between the reference points, determine the corresponding values of shifts and/or podemos path by comparing the results of measuring and certain provisions of the ways to design and improve the railway track in accordance with these values is MIS-shifts and/or podemos way. The position of the path between the reference points determined with the help of roaming by way of the measuring device, which measures the angularity of the path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measures the elevation of the path level and calculate the position of the path between the reference points in the fixed coordinate system taking into account the mentioned measurement krivolineynoe path and/or the measurement of the elevation path level (patent RU №2212486 C2, EV 35/00, UK 9/08, 05/02/2001).

A device for alignment of the railway track, which is described in the specified source containing the hoisting and pulling device and United with him measuring device with sensors measuring krivolineynoe path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measuring the elevation of the path level. This measuring device is equipped with a device for automatic positioning relative path marker placed on the side of the railroad tracks, and a computer with inputs connected to all the sensors of the measuring device and a device for automatic positioning relative path reference, and the output of the computer connected to the hoisting and pulling device.

SUBSTANCE: invention relates to methods of checking and forecasting condition of rail track. According to proposed method, running course of body of track-testing car is measured by means of inertia navigational system installed under pivot of test bogie, and running hunting angle of test bogie relative to body is measured by means of angular displacement transducer. Then, using axle box-rail transducers, distance from flanges of corresponding wheels of bogie to rail heads are measured. Basing on obtained information , running courses of rail lines are calculated as running course of body minus running hunting angle of test bogie relative to body minus running angle of parallel misalignment of flanges of wheelsets of test bogie and heads of rail lines. Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.

EFFECT: provision of chordless (single point) method of checking leveling of rail lines.
