RAILWAY TRACK ALIGNMENT METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC E01B35/00 

FIELD: track facilities.

SUBSTANCE: invention relates to track alignment and can be used in preventive maintenance, in setting the track to design position and in finishing the track after overhaul. Method consists in the fact that bending booms of rail lines in plan, rail lines by level, calculating the rail lines shift values and continuously or cyclically straightening the railway track in accordance with the rail lines shift values, before each cycle of track straightening, location of straightening device is determined, reducing measurement results with coordinate system of satellite base station using satellite positioning system. Straightening device comprises a lifting and straightening device, a computer, a measuring and control device including a distance traveled sensor, three measuring trolleys, cables stretched between measuring trolleys, and installed on them and connected to the computer rail lines bending sensors in plan, two satellite antennae connected to a satellite positioning system receiver, first and second inputs of which are connected to a computer and a modem receiving signals from a satellite base station and an actuator for displacing the cables in the horizontal plane, rigidly connected to the front measuring trolley, connected to the computer.

EFFECT: higher accuracy of track alignment and reduced time of its implementation.
