METHOD OF AUTOMATIC LOCK-ON CONNECTION OF PAIR OF STANDARD RAILS IN BLOCK WITH RAIL PAD Russian patent published in 2013 - IPC E01B9/44 B66C7/08 

FIELD: construction.

SUBSTANCE: method is realised with an automatic lock-on connection of a pair of standard rails with heads (1), journals (2) and feet (3) into a block with a double-headed rail pad (4), equipped with outer side heads (5) and L-shaped combs (6), aligned towards each other. Cams (7) with tails (8) are rested against the lower step of the pair of L-shaped combs (6). Heads of cams (7) are inserted under tails (9) of bracket-like clips (10), which are aligned and protrude with tails (9) outside. Short elements of bracket-like clips (10) are inserted under upper steps of the pair of L-shaped combs (6), and convex surface of bracket-like clips (10) tightly contact with journals (2) of the pair of rails and compresses them with each other. Heads of the cams (7) are used to jack tails (9) of bracket-like clips (10), to stress and lock the lock device for production of a rail block operating together as a single whole.

EFFECT: extended resource.
