METHOD FOR TAMPING OF RAILWAY TRACK TIES (VERSIONS), TIE-TAMPING UNIT (VERSIONS) AND TAMPER FOR ITS REALISATION Russian patent published in 2009 - IPC E01B27/12 E01B27/16 

FIELD: transportation.

SUBSTANCE: invention is related to methods for tamping of railway track by tie-tamping units with tampers installed in them. Method for ties tamping includes operations of tampers dislocation to zone above treated tie, submersion into ballast, dislocation of vanes under rail foot, dislocation to tie, withdrawal from under rail and their lifting with opening into initial position. In the first version - after position is obtained, which is closer to tie, tamper is lifted. Afterwards, tamper vanes are withdrawn under rail. In the second version - during tamping by unit with several additional levers on rotary levers during displacement of tamper vanes that are closer to rail under rail foot, vanes of other tampers are also moved to rail side, but by value that is less than value of tamper vanes closer to rail. In the first version of tie-tamping unit, elements of fixation relative to longitudinal axis of unit are installed at the angle different from 90°, which provides for position of tamper vane plane, at the angle of at least 90° from the side of tamped tie to vertical plane passing through longitudinal axis of unit. In the second version - additional axis and drive of additional lever rotation make it possible to install tamper vanes installed on opposite sides of rail at the distance from each other, which is less than width of rail foot of treated track. In tamper plane of fixation element location is arranged at the angle to vane plane, and angle is different from angle multiple to 90°.

EFFECT: compaction of ballast under tie directly under rail.
