METHOD OF AND DEVICE FOR STRAIGHTENING RAILWAY TRACK IN PLAN, PHYSICAL PROFILE AND LEVEL Russian patent published in 2008 - IPC E01B35/00 B61K9/08 

FIELD: railway transport; track facilities.

SUBSTANCE: invention relate to method of straightening railway track in plan, physical profile and level and to device for implementing the method and they can be used in scheduled preventive straightening out of track and finishing of track before handling over for operation after major repairs. According to proposed method, railway track is electronically marked out by fitting electronic marks on track axis on each hundred meter and kilometer mark, and scanners of said marks are installed on track measuring car on each track maintainer. Parameters of track rails in plan, physical profile and level are checked by electronic marks. Marks are uninterruptedly read out, their identification number are kept in memory and distance covered at moment of their detection is recorded. In process of calculations and corresponding shifts of track, data base of said electronic marks is formed containing information on location of each marks and distance between adjacent marks. Results of obtained calculations and data base of electronic marks are transmitted to dispatcher centers of track maintainers and further on to computers of said machines. Track is subjected to straightening out starting from set mark and continuously reading information from electronic marks and automatically correcting current index of program task in moment of detection of mark if measured distance from initial mark differs from Log value. Information on current calculated shifts of track is periodically renewed basing of subsequent passings of track measuring car and is transmitted to track maintainers. Invention increases capacity of machine maintenance of track, cuts down time taken for calculation of required straightening out of track, provides acceleration of total certification of geometrical parameters of rail track gauge geometry measuring device and improves quality of said device, provides automatic tie of readings of track maintainers to longitudinal coordinates of track owing to doubling of existing staking out with electronic marking out.

EFFECT: increased capacity of track maintainers.
