Definitions

  • the invention relates to a resilient rail fastening according to the preambles of claims 1 and 2.
  • Resilient rail fastenings of all kinds have been used successfully for decades. They have proven their worth especially when fastening rails to sleepers in the ballast bed. The track position is readjusted by working through the ballast and thereby moving the sleepers across the ballast bed.
  • resilient rail fastenings on firm carriageways there is a need for a firm connection of the rail fastening point on the ground and thus the need to align the rail in order to compensate for tolerances in the rail or settling in the rigid carriageway. Solutions are known for this, but as a rule they are extremely complex.
  • Resilient rail fastenings according to the preamble of claim 1 are known from DE 31 11 876 A1 and rail fastenings according to the preamble of claim 2 are previously known from DE-AS 1 261 151.
  • a side adjustment of the rail position for resilient rail fastening according to the aforementioned prior art is, if known at all, extremely complex.
  • the invention has for its object to develop resilient rail fastenings according to the cited prior art such that lateral adjustment of the rail position is made possible with simple means.
  • Fig. 1 shows the top view of a rail fastening point.
  • the rail 1 rests with its foot 2 on a base plate 3, which in turn is connected to the base 6 via screws 4 and anchors 5.
  • Threaded bolts 7 arranged on both sides of the rail 1 are firmly connected to the base plate 3.
  • the threaded bolts 7 are surrounded by an eccentric bushing 8 which rest with a collar 9 on the open loop ends 10 of the B-shaped clamping clamps 11 in the exemplary embodiment described.
  • the loop ends 10 project over the rail foot 2 with a certain distance 12, as can be seen in connection with FIG. 2.
  • the central section 13 of the tension clamp 11 rests in the tensioned state of the tension clamp 11 under pretension on the rail foot 2.
  • the tensioning of the tensioning clamp 11 takes place via a cooperation with the threaded bolt 7 Nut 14 which, with the interposition of a spring washer 15, pulls the eccentric bushing 8 downwards.
  • FIG. 2 The side adjustment of the rail fastening can be seen from FIG. 2 in connection with FIG. 1.
  • Guide plates 16 are arranged laterally against the rail foot 2. These guide plates 16 lie on the base plate 3 with the interposition of an intermediate plate 17.
  • An inclination plate 18 is used to set the usual rail inclination of 1:20 when the rail fastening is placed on a flat substructure.
  • the guide plate 16 is formed with a bore for inserting the eccentric bush 8. When the eccentric bushing 8 is rotated around the threaded bolt 7, the guide plate 16 thus describes a circular movement with respect to its position on the base plate 3.
  • the guide plate 16 on the rail foot 2 is formed with a rib 19 on which the open loop ends 10 of the tensioning clamps 11 rest in the tensioned state such that they protrude 12 above the rail foot 2.
  • the rib 19 also serves to keep the tension clamp retracted over the central section 13 in the preassembled state, in which the rail 1 can be inserted freely from above.
  • the guide plate 16 has a guide groove 20 in which the tensioning clamp 11 is supported in the assembled state.
  • the eccentric bushing 8 is formed with a collar 9.
  • the outer circumference of the eccentric bush 8 is slightly tapered downwards, which facilitates threading and tolerance compensation with regard to the tension clamp.
  • FIGS. 1 and 2 show the eccentric bushes 8 in the zero position, that is to say the rail 1 is held in the center on the rail fastening.
  • the threaded bolts 7, as can be seen in FIG. 1 are different, once to the front and once to the rear, each by the eccentric dimension 21 arranged outside the center of the base plate 3.
  • the rail fastening according to the invention also allows a gradual height adjustment of the rail in a simple manner.
  • the intermediate plate 17 only has to be exchanged for another intermediate plate of different thickness.
  • several intermediate plates 17 can be used.
  • the threaded bolts 7 must be adapted in terms of their length in such a height adjustment.
  • FIG. 3 An embodiment of the connection of the rail fastening described with a fixed roadway is shown in Fig. 3. Holes are provided in the subsurface 6 of the solid carriageway, in which the anchors 5 are introduced with a casting compound 22.
  • the potting compound 22 also serves to compensate for height tolerances of the base 6.
  • an elastic, resilient plate 23 is arranged, which serves for resilient support of the rail 1 on the base 6.
  • the armatures 5 are surrounded by bushes 24.
  • These sockets serve on the one hand for electrical insulation and are therefore made of electrically insulating material and on the other hand serve for resilient bracing of the base plate 3 on the substrate 6.
  • the actual bracing of the base plate 3 takes place by means of nuts 4 and spring washers cooperating with the anchors 5.
  • the guide plate 16 also has ribs 19 and a guide groove 20.
  • the guide plate 16 is designed as a cast part or a pressed plastic part and is therefore variable in terms of its shape.
  • the eccentric bushing 8 also engages around the threaded bolt 7 with its bore and lies with its eccentric outer surface 26 in a bore of the guide plate 16. Therefore, the side adjustment of the rail 1 takes place as previously described.
  • the collar 9 of the eccentric bushing 8 lies directly on the guide plate 16.
  • the surface 27 of the eccentric bushing 8 is higher than the lateral contact surface 28 of the rail foot 2 for the tensioning clamp 25 and is spherical.
  • the central loop 29 of the tensioning clamp 25 lies on the surface 27 of the eccentric bush 8, wraps around the threaded bolt 7 and projects beyond the rail foot 2 at a distance.
  • Nut 14 and spring washer 15 clamp the entire rail fastening.
  • the tensioning clamp 25 lies with its region facing away from the guide in the guide groove 20 of the guide plate 16. Ribs 19 serve to hold the support ends 30 of the retracted tensioning clamp 25 before the installation or when changing the rail 1.
