VERTICAL AND LATERAL ADJUSTMENT OF RAIL FASTENING ASSEMBLY Russian patent published in 2019 - IPC E01B9/30 E01B9/48 E01B9/66 

FIELD: construction.

SUBSTANCE: invention relates to vertical and lateral adjustment of rail fastening assembly. Device for adjusting the height of rail terminal surface (1A) above the under-rail base, on which the rail is mounted, in the rail fastening assembly comprises replaceable holder (800') terminals for replacement of first terminal holder, passing outside around anchor circuit (4B) and forming at rear part support surfaces (801a) to support terminal (3B; 300B), and front part has a flat front wall (8021) extending substantially over the entire height of said holder and forming a replaceable side support insulator with an electrically insulating bearing surface extending over the entire height of the front wall, which is configured to pass to a height corresponding to the maximum possible height terminal support surface of rail above the under-rail base. Device also includes replaceable pressure insulator (600B₂, …, 600B_n; 600C₁, 600C₂, …, 600C_n), which is not adapted for retention of the rail fastening terminal on the heel, but is made separately from the replaceable terminal holder, forming an electric insulating element for installation on the terminal support surface of the rail foot, and has thickness corresponding to the height of the terminal rail bearing surface.

EFFECT: more uniform distribution of load from rail, avoiding intensive wear of side support insulator.
