Definitions

  • the invention relates to a method for removing or replacing the intermediate layers between rail and threshold or threshold plate, wherein the rail is lifted by loosening the rail screws from the thresholds. Furthermore, the invention relates to a clearing device for clearing rail intermediate layers, which comprises a roving head in the advance direction and subsequently an elongated guide body and can extend over at least three thresholds and a feed drive is provided which is preferably used for the inventive method.
  • the replacement of the intermediate layers between rail and threshold or threshold plate has been made largely sections and by hand.
  • the intermediate layers are made of elastic or damping material such as rubber or plastic.
  • the intermediate layers are used in particular for concrete sleepers, as they have a lower vibration damping, than the previously used wooden sleepers.
  • the intermediate layers are subject to wear and must therefore be replaced at certain intervals.
  • the US-A-5 435 251 describes a method in which intermediate layers between rail and threshold are inserted substantially automatically by means of a machine.
  • the disclosed machine has a reaming head arranged in the advance direction and subsequently an elongated guide body and a feed drive. The disclosed machine can not move forward under the raised rail.
  • the inventive method is primarily characterized in that a clearing device is moved between the sleepers or threshold plates and the lifted rail.
  • the clearing device according to the invention is characterized in that the clearing head has from a common axis to the rear extending clearing fingers pointing downwards Räumhaken.
  • a clearing device is also provided, which is characterized in that a feed tong is provided for the feed drive, which is guided by the rail and has jaws for two-sided grasping the clearing device under the rail.
  • the reamer is preferably used in combination with a vehicle assembly having successively a screwing machine for loosening the rail screws, a tool trolley with a lifting device for lifting the loosened rails and subsequently a second screwing machine for screwing the rails.
  • a vehicle assembly having successively a screwing machine for loosening the rail screws, a tool trolley with a lifting device for lifting the loosened rails and subsequently a second screwing machine for screwing the rails.
  • Fig. 1 is a cross section through a rail of a track with lateral supervision on a threshold.
  • Fig. 2 schematically shows from the side of a portion of a rail in the raised state with inserted clearing device.
  • Fig. 3 shows the top view of the reamer in the position according to Fig. 2 .
  • the Fig. 4a and 4b show a longitudinal section through the clearing head of the reamer in two different functional positions.
  • Fig. 5 shows a detailed view of the lifting device for the rail and Fig. 6 the view of the feed tong for the reamer.
  • Fig. 7 shows a side view of the feed drive.
  • the Fig. 1 shows the structure of a rail fastening on a threshold 1.
  • the threshold usually sits in a ballast bed, which is not shown here.
  • the guide jaws 3, the foot 4 of the rail 5 are supported laterally.
  • the rails screw 6 hold on spring clips 7, the rail firmly.
  • the intermediate layer 8 is arranged for example rubber at each threshold.
  • the rail fastening shown here is only one of many possibilities.
  • the intermediate layer can also rest directly on the threshold. At the present The invention is always concerned with removing the intermediate layer 8 below the rail 5 and, if necessary, reloading it.
  • the FIGS. 2 and 3 show the reamer 9 in side view and supervision.
  • the reamer extends over at least 3 sleepers, so it always rests on 3 sleepers.
  • the clearing device comprises a front clearing head 10 and subsequently an elongated guide body 11.
  • the guide body 11 has two longitudinal struts 12 and a multiplicity of transverse struts 13.
  • rollers or sliders 14 are arranged on each of the transverse struts 13 arranged.
  • the rolling or sliding along the rail foot is particularly important where bumps such as welding burrs are to be overcome.
  • Fig. 2 is the rail 5 in the lifted off in the direction of arrow 15 state, the lifting by the in Fig. 5 illustrated lifting device takes place. From this lifting device is in Fig. 2 only one of the rollers 16 shown, which engages under the rail head 17. The rail is about 3 cm from the thresholds 1 lifted so that the reamer 9 between the rail 4 and the thresholds 1 can be pulled through with a corresponding feed drive.
  • the clearing head 10 comprises according to the Fig. 4a and 4b Clearance finger 18, which sit parallel to each other on a common axis 20 and extend from the clearing head to the rear.
  • Each clearing finger has a downwardly facing Räumhaken 19.
  • Fig. 4a was the clearing device pushed below the unillustrated rail foot on the intermediate layer 8 and the Räumhaken 19 summarize the intermediate layer 8.
  • the Räumhaken 19 may be formed so that the Räumfinger dodge upward resilient when the Räumwiderstand is too large, for example, if the liner is missing and therefore strike the Räumhaken on the threshold or threshold plate.
  • the Fig. 5 explains the lifting device for lifting the rail from the threshold.
  • Such devices are known per se.
  • the rail head 17 is engaged on both sides by the rollers of the roller tongs 21 and can be lifted by a hydraulic, not shown here, in the direction of the arrow 22.
  • the roller tongs 21 in turn can be actuated by hydraulic cylinders 23 and is seated in a box-shaped support frame 24.
  • the rail screws can be loosened continuously along a track, the rail can be raised and, after lowering, tightened again. In the off-hook condition, the reamer can do its job.
  • a feed tong 25 is provided which comprises two jaws 26, which are each pivotable about an axis 27.
  • the hydraulic cylinder 28 presses on both sides of the jaws 26 apart, whereby the reamer 9 is taken on both sides at the other end of the jaws.
  • the ends of the jaws are preferably equipped with friction surfaces 29.
  • the feed tong 25 is preferably guided by one or two guide rollers 30 on the rail 5. As a result, the ends of the jaws 26 are always in the correct position below the foot 4 of the rail.
  • the Fig. 7 shows an embodiment of the feed drive for the feed gun 25.
  • the feed gun 25 here has two successive guide rollers 30. However, it may also be sufficient to provide a single guide roller.
  • the feed and return thrust for the feed gun 25 is provided by the hydraulic cylinder 31.
  • This is hinged to a structural element 32 of the side wall of the vehicle, in particular a workshop car.
  • the hydraulic ram is extended and the feed gun 25 detects the reamer 9.
  • the hydraulic cylinder 31 pulls the feed gun 25 in the direction of arrow 33, taking with it the reamer 9. This clears the liner 8 from the threshold 1.
  • the feed movement may in any case continue until the feed tong 25 may be at a threshold abuts. It depends on the rail fastening construction whether the feed tong 25 can be pulled continuously over the sleepers or whether a partial detection and release of the clearing device is necessary.
  • the feed gun 25 is controlled so that before reaching the next threshold 1, the pliers release the reamer, is pulled over the threshold and attacked after passing the threshold again on the reamer.
