KNURLING SHOE FOR EMERGENCY TRAIN CARS RETURN ONTO TRACK, METHOD FOR SHOES PACKAGING AND DEVICE FOR METHOD REALISATION Russian patent published in 2009 - IPC B61K5/04 B61K5/06 B65D6/00 B65D19/00 

FIELD: railway transport.

SUBSTANCE: invention is related to devices for return of railway cars that went off track, to methods of shoes packaging and to devices for their packaging. Knurling shoe for return of emergency train cars to track is characterised by the fact that on lower side of casing in its middle and back parts multiple cells are arranged that are open from bottom, and cells are created by flanging and partitions of casing. Depth of cells increases from casing back part to its front part. In front part of the latter transverse front and back walls are arranged, in which, accordingly, front and back grooves are arranged for rail head of track. Shoe casing is arranged as cast from metal alloy on the basis of titanium. According to method for packaging of knurling shoes, at first shoes are oriented with their flanges opposite to each other and are installed on cassette base on back parts at the distance from each other that exceeds sum of two heights of front parts of shoes so that center of gravity of every shoe in specified position of shoe is arranged internal circuit of base. Then back parts of shoes are fixed on cassette base, and shoes are inclined to central vertical axis of cassette to contact with horizontal sections of flange, which are located in single vertical plane. Afterwards front part of each shoe is connected to cassette stand. Device for method realisation represents cassette that includes base and stand fixed on base with load eye at its end. Along base perimetre there are at least longitudinal flanges, distance between which is selected as less than width of shoe back part. Height of stand is more than shoe length, thickness of stand is less than width of every aperture arranged in transverse walls of shoe for track rail. Stand has facilities for connection of shoe front parts to it.

EFFECT: as a result, shoe bearing capacity and convenience of its use are increased.
