SIDE SUPPORT OF RAIL FASTENING FOR TURNOUTS ON REINFORCED CONCRETE BASE AND METHOD FOR REGULATING POSITION OF RAILS IN HORIZONTAL PLANE IN TURNOUTS WITH ITS HELP Russian patent published in 2024 - IPC E01B9/30 E01B9/48 E01B7/20 

FIELD: railway tracks.

SUBSTANCE: invention relates to design of the upper structure of a railway track turnouts, namely to means for adjusting the position of rails in the horizontal plane in turnouts on a reinforced concrete base. The rail fastening stop for turnouts on a reinforced concrete base contains a horizontal sub-terminal section, a through hole for the passage of a fastening element, a vertical section with an edge, a lower projection, limiting and guide projections. In this case, the horizontal sub-terminal section is made of such a width that when installing the spring terminal, the latter always rests with its side sections on the sub-terminal pad of the stop. The length of the stop in the area of the horizontal sub-terminal section is made with a displacement of the lower protrusion relative to that part of the stop that makes up the vertical section with the rib, by an amount from -6 mm to -2 mm and from +2 mm to +6 mm.

EFFECT: makes possible to adjust the position of the rail in the turnout relative to the reinforced concrete base by an amount of ± 6 mm using a universal stop for all sleepers of the rail turnout , which does not require changes to the equipment for the lower protrusion , in addition, the stop has a large force transmission area at the maximum angle, and also gets clogged less.
