Definitions

  • the present invention relates to a device for rendering rails safe, comprising the characteristics expressed in the preamble to claim 1.
  • railway lines are formed by a succession of rails set with their heads mutually adjacent one after the other and mutually connected by means of head welds.
  • Such welds also serve the purpose of compensating for length variations of the rails due to the sudden temperature changes whereto the rails are subjected.
  • the weld point generally constitutes the weakest point of a rail, and hence it is the one were a failure occurs most easily.
  • the whole line is paralysed and it is necessary to restore it as soon as possible.
  • the first solution obviously requires more time than the second one.
  • the head F is the upper part, destined to support the wheels of the trains.
  • the web G which is the thinnest part of the rail, is located between the head F and the flange S, which serves as a bearing on the sleepers.
  • the web G also exhibits two substantially vertical flanks L.
  • a first known manner of temporarily repairing the line provides for the use of a junction device able to be mounted on the rail in correspondence with the breaking point, which comprises two plate-like fish-plates that are mounted opposite on the two flanks of the rails, and one or more locking elements destined to maintain the two fish-plates tight against the flanks of the rails.
  • Said locking elements are C shaped and have two ends that face each other, whereof at least one is translatable, usually by means of screwing, in such a way as to be able to be approached or moved away from the other, to tighten or release the rails.
  • the locking elements since they must not interfere with the operation of the rail, are mounted around the flange thereof in such a way as to tighten, with their ends, the two fish-plates against the flanks of the rail.
  • the tightening force is adjusted by screwing the movable end of the locking element.
  • Said welding beads prevent a correct positioning of the fish-plates, which are not able to adhere in an optimal manner to the flanks of the two rails to be joined. Before mounting the junction device, therefore, it is necessary to eliminate the welding beads.
  • devices of this kind exhibit a certain constructive complication (two plates, C shaped locking elements) which makes their installation laborious.
  • the device is constituted by two complex connecting elements, each constituted by two plates able to be associated to the two rails, and by a connecting element between the plates which allows not to interfere with the welding beads.
  • On the two connecting elements are operatively active at least two locking elements of the kind described above.
  • the device for rendering safe two mutually adjacent rails comprises a first locking element able to be operatively associated to a first flank L of the rails, and one second locking element able to be operatively associated to a second flank L of the rail.
  • the first locking element comprises a base portion able to be associated to the rails below the flanges, and extending, transversely to the rails, from a first end to a second end, and an upper portion superiorly integral with the first end of the base portion and having a face able to be associated in abutment against the flanks of the rails.
  • the second locking element has a face able to be associated in abutment against the flanks of the rails.
  • Connecting means connect the second locking element to the second end of the first locking element.
  • the technical task constituting the basis for the present invention is to provide a device for rendering rails safe, which overcomes the aforementioned drawbacks.
  • a technical task of the present invention is to provide a device for rendering rails safe which has a reduced cost and allows to render broken rails safe in an easy and rapid manner.
  • Yet another technical task of the present invention is to provide a device for rendering rails safe which can be used also for the construction of temporary tracks.
  • the reference number 1 globally indicates a device for rendering rails 2 safe, according to the present invention.
  • the device of the present invention can be applied to the rails 2 in correspondence with a breakage point thereof, or in general with a junction point 3.
  • flanks 4 of the webs of the two rails oriented towards one side of the rail 2 and the two flanks 5 oriented towards the other side are defined as first and second flanks 4, 5 of the two rails 2.
  • the device I comprises a first locking element 6 able to be operatively associated to the first flanks 4, a second locking element 7 able to be operatively associated to the second flanks 5 and means 8 for connecting the first locking element 6 to the second locking element 7.
  • both the first and the second locking element 7 are constituted each by a single piece of contoured material.
  • the locking elements 6, 7 can be made of metallic material (iron, steel, ...), of carbon fibre, resin, or any other material suitable for the purpose.
  • the first locking element 6 is constituted by a base portion 9 and by an upper portion 10.
  • the two ends 11, 12 of the base portion 9 project laterally relative to the rails 2, when the device 1 is installed.
  • the upper portion 10 also has a first face 13 able to be associated in abutment against the first flanks 4 of the rails 2, whereto it is advantageously counter-shaped.
  • the second end 12 has at least a first through hole 14.
  • first through holes 14 are provided, having mainly vertical development.
  • the second locking element 7 has a second face 15 able to be associated in abutment against the second flanks 5 of the rails 2 relative to which it is preferably counter-shaped.
  • the second locking element 7 is mounted in removable fashion above the second end 12 of the base portion 9 of the first locking element 6, and it has at least a second through hole 16 (two in the illustrated embodiment) aligned to the first through hole 14. In this way, the connection between the two locking elements 6, 7 is obtained through at least a bolt 17, two in the illustrated embodiment, inserted through the first and the second through hole 14, 16 ( Figures 2 and 3).
  • the second through hole 16 can be threaded in such a way as to constitute a threaded seat.
  • the connection between the two locking elements 6, 7 can be obtained by means of a screw inserted through the first through hole 14, and screwed in the threaded seat (this embodiment is not illustrated herein).
  • first and the second face 13, 15 respectively exhibit a first and a second groove 18, 19 developing mainly in a substantially vertical plane, parallel to the first direction of development.
  • Each groove 18, 19 is obtained in an intermediate area 20, 21 of the faces 13, 15, with reference to a horizontal direction perpendicular to the first direction of development, and allows to mount the device 1 in the presence of welding beads 22 between the two rails 2.
  • the base portion 9 is substantially counter-shape with respect to the flanges of the rails 2, and the first groove 18 extends without interruptions also on said base portion 9 to allow mounting the device 1 even when the welding beads 22 between the two rails 2 develop also below the flanges.
  • the mounting of the device 1 for rendering rails 2 safe of the present invention is achieved by initially inserting the first locking element 6 underneath the rails 2 in such a way as to bring the first face 13 to adhere against the flanks of the rails 2.
  • the second locking element 7 is positioned on the second end 12 of the base portion 9 of the first element and the screws are inserted in the through holes until they are screwed in the appropriate seats.
  • the present invention achieves important advantages.
  • the device for rendering rails safe of the present invention has a reduced cost which allows to render damaged rails safe in an easy and rapid manner, requiring limited operating times.
  • said device can also be used for the construction of temporary track segments, such as those of a railway construction site.
