Assemblies including railroad rail jamb insulators and railroad rail clip anchors for use therewith

Abstract

In an assembly including a first rail rail jamb insulator and a rail rail clamp anchoring device (3) for retaining a resilient rail rail fastening clip (6), the rail rail clamp anchoring device (3) is configured to support the first rail Rail jamb insulator (1'), a first railroad rail jamb insulator (1') configured to be positioned on the upright side (21A) of the foot (21) of the railroad rail (2) and adjacent the foot (21) of the rail An electrically insulating bearing surface (10') is provided between the upright bearing surfaces of the railway rail clamp anchoring device (3), and the electrically insulating bearing surface (10') is provided by the outside of the wall (100') of the insulator. The insulator further includes a member (110') connected to the inner face (12') of the wall (100'), the member (110') having a direction extending in a substantially perpendicular direction relative to the electrically insulating load-bearing surface (10') to a distance from the wall (100'). The depth (d0) of the inner face of 100') is greater than or substantially equal to the top surface (11') of the depth (dw) of the wall in said direction. A railway rail clamp anchoring device (3) having an upright load-bearing surface, including a front wall surface (301, 303, 304) configured to be positioned adjacent a foot (21) of the rail, in a direction substantially perpendicular to the front wall surface (301, 303, 304) an upper center surface (302) offset from the front wall surface (301, 303, 304) by an offset distance (D) between one-tenth and one-half the depth (D0) of the railway rail clamp anchoring device (3), and Upward facing portion of the rail rail clamp anchorage (3) extending from the upper center plane (302) to provide a shelf portion (31) for receiving the member (110') of the first rail rail jamb insulator (1') surface.

Description

technical field [0001] The present invention relates to an assembly comprising a railway rail jamb insulator and a rail clip anchor for use therewith. Background technique [0002] Railroad rail fastening assemblies that employ elastic rail fastening clips to secure the rails include, in addition to the rail fastening clips that bear down on each side of the foot (foot) of the railroad rails, a rail for holding each railroad rail tight. Some kind of railway track clamp anchoring device for clamping. Some of the rail fastening clips are driven onto the rail in a direction parallel to the length axis of the rail and some of the rail fastening clips are driven onto the rail transversely. Some laterally driven clips can be held within the anchor in a position where they are not supported on the rail, for example to allow pre-installation of the rail fastening assembly on the sleeper prior to transport to the site, or to allow side rails carried by the anchor to Post electrical...

Problems solved by technology

However, the problem remains that in order to provide all combinations, 11 different jambs would need to be provided at each of the 3 different heights, which gives 33 combinations

Each of these has to be manufactured, and because of the many different parts that need to be worked on, it is difficult logistically and difficult to adjust in practice
