METHOD OF AND DEVICE FOR RE-LAYING RAIL LENGTHS OF CONTINUOUS WELDED RAILS ON CURVED SECTIONS OF TRACK Russian patent published in 2004 - IPC

FIELD: transport; permanent way.

SUBSTANCE: method relates to repair of rail lengths of continuous welded rails. According to proposed method, sections of beginning and end of rail lengths to be re-laid are determined, rail lengths to be-laid are unfastened, frame for re-laying rail lengths are charged and said frames are connected to each other and to movable unit by tie-rods. Movable unit with connected frames is moved from beginning of rails to be re-laid to end and re-laid rail lengths are fastened on rail base-plate. Device are placed under foot of re-laid rail lengths to decrease resistance forces to longitudinal displacement of rail lengths. Immediately after lifting the rails devices reducing longitudinal displacement resistance forces of rail lengths are removed from ribs of baseplates. Device contains first frame resting on supports with two rollers for moving rail lengths installed on frame from both sides in longitudinal symmetry plane, second frame resting of supports with two rollers installed at both sides of longitudinal symmetry plane of device. Frames are interconnected by pair of rigid tie-rods. First frame is connected with movable unit by other pair of rigid tie-rods.

EFFECT: improved accuracy of setting sections of beginning and end of rail lengths.
