METHOD OF REARRANGEMENT OF CONTINUOUS WELDED RAIL LENGTHS IN CURVILINEAR SECTIONS OF TRACK Russian patent published in 2006 - IPC E01B29/05 

FIELD: railway transport.

SUBSTANCE: invention relates to railway transport and it can be used to increase service life of continuous welded rail lengths in curvilinear sections of track. According to proposed method cross-sections of rails lengths at beginning and end of section are determined, rail lengths are unfastened and devices reducing resistance to longitudinal displacement of rail lengths are placed under rail foot. Then initial sections of rail lengths are shifted into new position and fastened. Frames for rearrangement of rail length are charged and connected to each other and to hauling unit by rods tie. Using said hauling unit, frames for rearrangement of rail lengths are displaced in direction from beginning to end applying preliminarily determined longitudinal forces in direction from end to beginning to inner line under rearrangement and preliminarily found longitudinal forces in direction from beginning to end to outer line under rearrangement, devices reducing resistance to longitudinal displacement of rail lengths are removed immediately after raising of rail lines from baseplate flanges and rail lengths are fastened in new position on underrail base.

EFFECT: provision of uniform stresses in rearranged rail lengths, dispensing with additional labor input for their adjustment in rearranged rail lengths.
