Definitions

  • the invention relates to a device for fastening a rail for rail vehicles.
  • DE 44 06 105 A1 describes a rail mounting on two steel beams, in which a first pair of bolts presses a rail by means of clamps against a ribbed plate, wherein the ribbed plate is fixed via a second pair of bolts without clamps on the steel beams.
  • the rails are not mounted directly on the threshold, but on expensive to produce rail mounting plates, which in turn are welded to the threshold.
  • the inventive concept of a rail fastening allows the anchor member has essentially the task to fix the rail in the vertical against the metal sleeper, while occurring in operation transverse forces of the rail are primarily introduced via the support member and the cross brace in the metal sleeper.
  • transverse forces of the rail are primarily introduced via the support member and the cross brace in the metal sleeper.
  • a division of the acting forces is achieved, which allow a total of large operating forces with a long service life and prevent wear of the metal sleepers.
  • the anchor member has a free play in the opening in the transverse direction under operating conditions, a support of the transverse forces at the edge of the opening is avoided. This reduces the risk of cracking on the metal sleeper.
  • Thresholds made of steel are preferably understood as meaning a metal sleeper.
  • the shaping of the metal sleeper can, apart from the features according to the invention, take place in a conventional manner, for example as an open or closed trough threshold, as I-threshold, T-threshold or otherwise.
  • a metal sleeper is understood to mean any metallic base, that is, for example, metal plates which have several directions according to the invention in the direction of travel of the rail, but not from several elements, known Y-steel sleepers, in which two curved steel profiles by bolts welded or connected together on the top and bottom.
  • a tension clamp is within the meaning of the invention, each resilient means which can be acted upon by a clamping path with a defined bias and presses the rail by means of the bias down in the direction of the metal sleeper.
  • Usual tension clamps are often pre-bent from correspondingly elastic round material.
  • an anchor member is generally understood to mean any fastening means capable of being subjected to tension, which on the one hand is held against the metal sleeper and holds the rail down against the metal sleeper.
  • Examples of preferred anchor members according to the invention are positively held in the metal sleeper bolts with a thread at an upper end.
  • the bolt can be plugged, for example with a bolt head at a lower end through a slot in the metal sleeper and then twisted to make a positive connection.
  • the transverse direction extends in the sense of the invention horizontally and transversely to an extension direction of the rail.
  • the rail is insulated by means of electrically insulating components relative to the metal sleeper.
  • the electrical insulation can be done for various purposes, for example as a safety mechanism or for signaling reasons.
  • the insulating components may in particular consist of a plastic.
  • an insulating sleeve may be arranged around the anchor member.
  • the holding member comprises an angle guide plate for the tension clamp.
  • an angle guide plate supports the tension clamp and guides it in the course of a tension during assembly of the rail.
  • the angle guide plate can also be a stop e.g. for a nut, so that a precise bias of the tension clamp is defined.
  • the angle guide plate may be at least partially formed of an electrically insulating material. This allows in a particularly simple manner electrical insulation of the rail against the metal sleeper.
  • a positioning of the rail with respect to the metal sleeper in the transverse direction can be selected by means of the retaining member.
  • holding members of different widths can be prefabricated.
  • the holding members may comprise usable laterally acting spacers, which are present in different widths and are selected as required.
  • the holding member is formed elastically deformable in the transverse direction. This can be done by deliberately provided beads, material recesses or the like. A spring constant of the holding member in the transverse direction can be optimized by such measures or adapted to the operating forces expected to lateral forces.
  • the metal sleeper may be shaped as a trough sill.
  • Trough sleepers are particularly suitable for transferring high transverse forces into a ballast bed and can be ideally combined with an attachment according to the invention for the rail.
  • the transverse support may comprise a longitudinal body extending in a rail longitudinal direction and releasably - for prefabrication with adaptation to different track widths - or insoluble, z. B. by welding, be connected to the metal sleeper.
  • the longitudinal body extends substantially over a length of a support surface of the rail on the metal sleeper, so that an optimal distribution of the introduction of force via the threshold width.
  • the fastening device comprises a metal sleeper 1 extending in a transverse direction, on which two parallel, perpendicular to the transverse direction in a Rail longitudinal direction extended rails 2 are applied to guide a rail vehicle.
  • the metal sleeper 1 is presently designed as a trough threshold of a correspondingly formed steel sheet.
  • the determination of the two rails 2 is identical, so that reference will be made hereinafter only to the definition of one of the rails.
  • two openings 3 are introduced in the steel sleeper, which are arranged in the manner of in the transverse direction, d. H. are also orthogonal to the rail extending, elongated holes are formed.
  • the transverse supports 4 are formed as simple strips which extend in the rail longitudinal direction. In this case, the transverse supports 4 extend at least approximately over a length which corresponds to a bearing surface of the rail 2 on the metal sleeper 1.
  • the openings 3 are arranged within the region between the transverse supports 4.
  • the rail 2 is supported on the metal sleeper 1.
  • an intermediate plate 5 made of an elastic material, in the present case a plastic is inserted between the rail 2 and the metal sleeper 1.
  • the intermediate plate 5 assumes no functions of reinforcing the metal sleeper, so that the rail 2 rests directly on the metal sleeper 1 with respect to the supporting forces.
  • a holding member 6 is arranged between the respective transverse support 4 and a rail 2a of the rail 2.
  • the holding members 6 are formed identical on each side of the rail.
  • Each of the two holding members 6 comprises an angle guide plate 7, a tensioning clamp 8 and an anchor member 9.
  • the angle guide plate 7 rests on the metal sleeper 1 and supports or guides the resilient tensioning clamp 8.
  • the tensioning clamp 8 is on one side guided in recesses 7a of the angled guide plate 7 and engages with another side from above the rail 2a.
  • the anchor member 9 is formed as a bolt-like tie rod having an elongated closure head 9a at a lower end and an external thread 9b at an upper end.
  • the anchor member is inserted with the closure head 9a through the respective opening 3 of the metal sleeper 1 and twisted to produce a positive connection.
  • the angle guide plate 7 and the tension clamp 8 are placed over the anchor member and the tension clamp is tightened by means of a nut 10 corresponding to the external thread 9b and washers 11.
  • the clamp presses the rail 2a substantially vertically downwards against the metal sleeper 1.
  • the anchor member has sufficient clearance in the slot in the transverse direction, so that lateral forces are not introduced by a contact of the anchor member in the opening 3 in the metal sleeper 1.
  • the holding member 6 or the angled guide plate 7 fills the area between the rail foot 2a and the transverse support 4 without play, so that transverse forces occurring during operation are introduced into the transverse supports via the holding members.
  • the angle guide plate 7 rests with a contact edge 7b on the transverse support 4, so that the force is distributed over the length of the transverse support.
  • An extension of the angle guide plate also overlaps the transverse supports 4 in the region of the contact edge 7b.
  • the angle guide plate is designed to be elastic in the transverse direction, wherein a spring constant is chosen in this direction according to the expected force peaks. These are in the Angled guide plate specifically formed weakenings 7c, which allow an elastic deformation by a corresponding certain stroke.
  • the device also allows, if necessary, an electrical insulation of the rail 2 with respect to the metal sleeper 1, for example for the construction of conventional safety circuits in the field of signal boxes or the like.
  • the intermediate plate 5 some components such as the intermediate plate 5 are formed of an insulating material such as plastic.
  • the anchor member is isolated from the tension clamp 8, for example by means of a sleeve 12 surrounding the anchor member 9 made of plastic.
  • the washers 11 pressing on the tension clamp should be selected from insulating material.
  • angle guide plate 7 may be formed for the purpose of isolation of plastic.
  • the angle guide plate may also be made of metal and for a corresponding insulating plate between the rail 2a and the angled guide plate may be provided.
  • angle guide plates of different widths can be provided. In each case, pairs of angle plates are selected and combined, which ensure a total play-free support between the cross supports 4.
  • the position of the rail 2 relative to the apertures 3 can be changed to some extent. Alternatively, it is also possible to ensure the positioning of the rail by appropriately assembled additional spacers in the transverse direction.
