Description

  The present invention relates to means and methods for adapting rail rail fastening assemblies to changes in rail clip bearing surface height of a rail rail above a rail foundation.

  Railroad rail fastening assemblies typically include railroad rail fastening clips, each having a clip toe that abuts the clip bearing surface of the rail foot, and each of the clips secured to the underlying rail foundation. Supporting rail clip fastening devices, which are disposed on opposite sides of the rail at various points along the rail fastening devices. It may be necessary to change the rail rail height above the rail foundation by adding or removing shims under the rail feet (or the underlying base plate). In some cases, future height adjustment needs are anticipated, in which case a rail rail fastening assembly designed to allow height adjustment is first supplied. However, if it is not anticipated that some height adjustment will be necessary, it may be necessary to make adjustments for significant changes in height. In addition, in some situations where some requirement for height adjustment is highly localized and may account for only a small percentage of the overall requirements for the fastening assembly, a standard system, That is, a system that is not designed to be height adjustable is used everywhere along the rail track, and in a limited number of places where this is necessary, the height adjustment system is abutted against the fastening assembly. Used to adapt to the height.

  Typically, the rail fastening assembly is of the type in which the rail fastening clip is driven onto the rail foot in a direction parallel to the longitudinal axis of the rail or the rail fastening clip is laterally, ie the longitudinal axis of the rail. One of the types driven on the rail foot in a direction perpendicular to the rail. An example of the latter type is shown in FIG. 1 of the accompanying drawings, which is a European patent application publication 0619852 which describes a clip 3A which can be driven in a substantially M-shaped side view in plan view. The specification (A1) and European Patent Application No. 0619851 (A1) which describe a fastening device 4A for holding the clip 3 on the rail clip bearing surface 1A of the rail 1 are disclosed. The clip 3 </ b> A supports the electrically insulating toe insulator 6 on the toe 34. The anchoring device 4A is a base 41 configured to secure the anchoring device 4A to the lower rail foundation 2, and two spaced apart positions extending from the base 41 and defining an opening for receiving the tow of the clip therebetween. And a head 40 with a load bearing surface 43 positioned adjacent to the rail when the anchoring device is in use, and the load is routed from the foot of the rail through the anchoring device. Is transmitted to the lower rail foundation. A side post insulator 5 (typically made of Nylon ™) with an electrically insulating load bearing face is also provided between the rail foot and the bearing bearing bearing surface. Yes.

  It is undesirable to use a standard form of such an anchoring device when adjusting the height of the rail. This is because the lateral bearing area provided to the rail by the anchoring device suddenly decreases to zero when the rail is moving upward relative to the anchoring device. In particular, when the entire rail is positioned above a certain height with respect to the anchoring device, the anchoring device cuts straight into the side post insulator when a load is directed through the side post insulator. It only provides two thin vertical strips (two ends of the wall spaced apart).

  A variant of the rail fastening assembly of EP 0619851 (A1) and 0619852 (A1) is known, in which the anchoring device is more than standard. Manufactured to have a high load bearing surface, so when the shim is inserted under the rail (or base plate) to increase the height of the rail, the load from the rail (or base plate) will be extended It can still be sent inside. The tall anchoring device employs a standard clip that maintains its normal position by substituting a compensatory toe insulator that is gradually thinner, so the deflection of the clip is at all height adjustment positions. So that it remains substantially constant. Such anchoring devices are very tall and employ more material, so such anchoring devices are heavy and expensive to manufacture. Furthermore, if a requirement for significant height adjustment is not anticipated, work must be performed on the track to replace the standard height anchoring device with a tall anchoring device.
