Definitions

  • the present invention concerns a device for maintaining the spacing of railroad rails.
  • a device of this type called a "gauge rod" is used to temporarily maintain the spacing of two rails of a railroad track when a defect has been noted in the anchoring of a rail. It comprises a rod having a length greater than the spacing of the rails, two pairs of jaws mounted on this rod, each of which is able to grip the base of a rail, and organs for immobilizing the jaws relative to the rod.
  • the existing gauge rods have the drawback of not being very practical to use and requiring a long time to place or remove, which is a significant drawback given the relatively brief time allowed to repair the anchoring of a rail.
  • the existing gauge rods also have the drawback of being relatively fragile and risk being damaged during the various manipulations to which they are subjected during their use.
  • the present invention aims to resolve the drawbacks of the existing gauge rods.
  • a gauge bar can be left in place for a certain duration, the time for the repair to be scheduled and performed.
  • the invention also aims to provide a gauge bar resolving these same drawbacks while having a structure allowing it to be left in place for the time needed to repair the rail anchoring.
  • the concerned device comprises, in a known manner, a rod having a length greater than the spacing of the rails, two pairs of jaws mounted on this rod, each of which is able to grip the base of a rail, and organs for immobilizing the jaws relative to the rod, the means for immobilizing the jaws relative to the rod comprising a threading arranged on the rod, or threaded portions arranged on the rod at suitable locations, and nuts engaged on this threading or these threaded portions.
  • the device comprises tubular sleeves able to be engaged and maintained on the rod so as to protect said threading or said threaded portions of the rod.
  • the gauge rods currently used do not comprise means for immobilizing the jaws relative to the rod in the form of a threading or threaded portions on the rod, and nuts engaged on this threading or these threaded portions, due to the risks of possible deterioration of the threading(s) during manipulations for placement, removal and storage of the rods, and also due to deteriorations taking place during passages of trains or other vehicles driving on the railroad track, these passages being able to create projections of stones or gravel, or even ballast stones, on the rod.
  • the invention consists of providing, on one hand, one or several threadings on the rod and nuts engaged on this or these threading(s), and, on the other hand, tubular sleeves which make it possible to protect this or these threading(s) with regard to possible deteriorations thereof.
  • the threading(s)/nuts system allows a relatively simple and quick placement of the device, and has, with regard to maintenance of the rails, a sufficient resistance for the device to be able to be left in place for a certain duration, without risk of reducing the maintenance of the rails. Thanks to the protection of the threading(s), the risk of deterioration of the threading(s) is eliminated, both during manipulations of the device and during the passage of trains.
  • the device comprises at least one nut axially connected to a protective sleeve, in particular integral with this sleeve.
  • the device advantageously comprises nuts designed to be used as nuts and nuts designed to be used as locknuts; in this case, at least one nut designed to be used as a locknut is integral with a protective sleeve.
  • Figure 1 is a general view after placement around two rails of a railroad track
  • figure 2 is an enlarged view of part of this device, with partial cross-section.
  • Figure 1 shows a device 1 for maintaining the spacing between rails 100 of a railroad track, used to temporarily maintain the spacing of two rails 100 when a defect has been observed in the anchoring of a rail.
  • the device 1 comprises a rod 2 having a length greater than the spacing of the rails 100, two pairs of jaws 3 mounted on this rod 2, each of which is able to grip the base of a rail 100, and nuts and locknuts for keeping jaw supports 4 of each jaw 3 in the gripping position around the bases of the rails 100.
  • the rod 2 comprises threaded portions
  • the nuts 6 and locknuts 7 are screwed on these threaded portions 5, in order to maintain the jaw supports 4 in the gripping position.
  • each locknut 7 is integral with a protective sleeve 8 which, engaged on the rod 2, covers all of the corresponding threaded portion 5.
  • the system of threaded portions 5, nuts 6 and locknuts 7 allows relatively easy and quick placement of the device 1 , and has, with regard to maintaining the rails 100, a sufficient resistance for the device 1 to be able to be left in place for a certain time, without risk of decreasing the maintenance of the rails. Thanks to the protection of the threaded portions 5 by the sleeves 8, the risk of deterioration of the threading(s) is eliminated, both during manipulations as well as placement and removal of the device, and during the passage of trains.
  • the placement of the sleeves is done simultaneously with the placement of the locknuts 7, such that there is no risk of forgetting to place these sleeves 8.
  • the invention provides a device 1 for maintaining the spacing of railroad rails which resolves the drawbacks of similar devices of the prior art.

Abstract

La présente invention concerne un dispositif (1) comportant une tige (2) ayant une longueur supérieure à l'écartement des rails (100), deux paires de mâchoires (3) montées sur cette tige (2), dont chacune est capable de saisir la base d'un rail (100), et des organes pour immobiliser les mâchoires (3) par rapport à la tige (2), le moyen d'immobilisation des mâchoires (3) par rapport à la tige (2) comprenant un filetage disposé sur la tige (2), ou des parties filetées (5) disposées sur la tige (2) à des emplacements appropriés, et des écrous (6, 7) engagés sur ce filetage ou ces parties filetées (5). En outre, le dispositif (1) comporte des gaines tubulaires (8) aptes à s'engager et se maintenir sur la tige (2) afin de protéger ledit filetage ou lesdites parties filetées (5) sur la tige (2).
