Embodiment Construction

[0023] Such as Figure 2A with Figure 2B shown in the figure 1Adapting means embodying the first aspect of the invention for use in adapting a rail clamp bearing surface 1A of a rail 1 above a rail base 2 on which the rail is located, for a rail fastening assembly of the type shown in It includes removable anchor extension assembly 700, replacement jamb insulation 500A (A 1 -A n ), replace the toe insulation 600A (A 1 -A n ) and replacement rail clamps for all but very small height adjustments that still apply to the standard rail clamp 3A. The height of the rail clamp bearing surface 1A is determined by adding between the rail foot and the elastic under-rail pad 9 on the rail base 2 (in this case concrete sleepers, but alternatively wooden sleepers, slab tracks or floor) Or remove shim 10 to change.

[0024] In particular, will figure 1 A method of adapting a track rail fastening assembly of the type shown in to the height variation of the rail clamp bearing surface ...

Abstract

An adaptation device for use in adapting a track rail fastening assembly to a change in height of a rail clamp bearing surface (1A) of a track rail (1) above a track base (2) on which the rail is located, comprising: Removable anchor extension assembly (700) configured to provide one or more extended load bearing surfaces (701a) through which loads may be transmitted from the rail foot to the anchor (4A); replacement jamb insulation (500A) , which is configured for use in the track rail fastening assembly in place of the first jamb insulator; replaces the toe insulator (600A), which is not adapted to be retained on the toe of the track rail fastening clip and separates from the jamb insulator, The replacement toe insulator is configured to provide the position of the clip bearing surface of the rail foot with an electrically insulating member having a thickness suitable for the height of the clip bearing surface.

Description

technical field [0001] The present invention relates to an apparatus and method for adapting a railway rail fastening assembly to variations in height of a rail clamp bearing surface of a railway rail above a rail bed. Background technique [0002] A track rail fastening assembly generally includes: track rail fastening clips (clips), each having a clip toe bearing on a clip bearing surface of a rail foot; and a clip anchor fixed to the subgrade below the rail and holding each clip, The anchors are disposed opposite each other on either side of the rail at intervals along the rail. It is sometimes necessary to change the height of the track rail above the rail base by adding or removing shims below the rail foot (or below the base plate). In some cases where the need for future height adjustments is anticipated, track rail fastening assemblies designed for height adjustments are supplied at the outset in these cases. However, sometimes it is necessary to adjust for signifi...
