Definitions

  • the invention relates to a rail extension device with mutually longitudinally displaceable and transverse to the rail longitudinal direction each other force-loaded jaw and tongue rail.
  • Rail extension devices also known as expansion joints - z. B. installed in the area of bridges to allow a relative movement between the structure and track.
  • the tongue rail is displaceably arranged relative to the stock rail.

  • Tongue rail foot and jaw rail foot start from a common base plate, such.
  • DE-A-1 534 052 illustrates.
  • a stock rail can be slidably disposed to a tongue rail, wherein the tongue rail is processed according to the bending line of the stock rail.
  • An expansion joint for grooved rails provides a welded to a guide plate rail section, wherein the guide plate is slidably mounted in the longitudinal direction of the expansion joint on a sliding chair.
  • the tongue rails are usually welded to the adjoining control rail. If replacement is necessary due to wear of the tongue rail, expensive work must be carried out. Also, not any materials can be welded together, so that there is the disadvantage that hard-to-weld wear-resistant steels are basically not used.
  • the present invention is based on the object, a rail extension device of the type mentioned in such a way that a quick replacement of the tongue rail is possible or the tongue rail may consist of materials that are not welded or made of hard to weld wear-resistant steels.
  • the invention essentially provides that the tongue rail is detachably received at a distance to its voltage applied to the stock rail area from a holder and that the tongue rail in the holder with a control rail or a portion of a control rail or a transition into the control rail section the holder is positively and positively connected.
  • a separate holder is used in which the tongue rail with the control rail is releasably connected directly or indirectly positively and positively.
  • the holder can pass directly into a portion of the control rail, so that the detachable connection is made with the portion of the holder and a remaining portion of the control rail.

  • the teaching of the invention is applicable.
  • the stock rail is slidably disposed to the tongue rail, wherein the tongue rail rests on a support, which in turn is inner guide as the first guide for the stock rail.
  • the stock rail is at least partially on an outer guide as a second guide.
  • the second guide is connected to a base plate as welded, emanating from a Beischiene, which in turn is preferably also connected by welding to the first guide in the form of a guide rail.
  • the guide strip should engage with its longitudinal edge region remote from the cheek rail in a geometrically adapted longitudinal recess of the insert rail.
  • spacer elements such as strips can be inserted between side rails facing away from the side of the tongue rail and facing inner surface of the rails, which are in particular screwed to the guide rail.
  • a vertical adjustment of the tongue rail can be prevented, that the tongue rail suppresses the stock rail in the head area.
  • the teaching of the invention results in particular for Rillenschienenauszugs- devices a simple construction that is designed to be extremely easy to maintain due to the interchangeability of the tongue rail.

  • the guide rail can be supported on the base plate outgoing supports such as plate elements, so that bending in the vertical direction is excluded even under heavy use.
  • the holder should be block-like and in particular has two channel-like recesses extending in the longitudinal direction of the rail, wherein the tongue rail with its root and a wedge element are introduced in a recess via which the tongue rail is fixed or positively and non-positively connected to the adjacent control rail or a section of this is connected. The wedge element is then fixed by means of fastening elements extending in sections within the second channel-shaped recess, such as screws.
  • the spacer elements or strips which are preferably bolted to the guide bar, are released. Then the wedge elements are removed so that the tongue rail is removable and replaceable by a new one. Any work on the stock rail or its outer guide are not required in contrast.

  • Fig. 4 is a section along the line C-C in Fig. 1 and
  • a rail extension device 10 is shown purely in principle, which relates to grooved rails, without this being intended to limit the teaching of the invention. Rather, this also applies to other rail profiles, especially Vignole rails.

  • the rule rails 16, 18 are made of rail steel. Since the tongue rails 21 are exposed to a special wear, these may be due to the fiction, contemporary teachings from hard to weld or not weldable materials, especially high-strength steels, since the tongue rails 21 in the control rails 16, 18 form-fitting and non-positively transition without weld.
