Definitions

  • the present invention relates to a fastening of rails for railroad switching, in which the inner foot of the rail is removed to allow the installation of a movable needle which is movable transversely relative to the web of the rail, comprising a fixing shoe having an overall "L" section, one of the branches of which is bolted to a sole secured to a cross member and the other branch of which is bolted to the web of the rail, on the side opposite the needle mobile.
  • the railroad tracks are not rigidly fixed on their sleepers, but so as to keep a certain flexibility to better resist the numerous stresses to which they are subjected, in particular those resulting from expansions and those imposed by the passage convoys.
  • the longitudinal edges of the foot of each rail are fixed to the crosspieces by flexible collars, the edges of which rest on the foot of the rails under the action of the tightening bolts screwed into the crosspieces or in soles integral with the crosspieces. .
  • the aim of the present invention is to provide, from the general state of the art according to the preamble, an elastic fixing of the rails at the level of the switches, which eliminates the drawbacks described above.
  • the binding proposed by the present invention includes the features of claim 1.
  • the fastening with vertical elasticity can be carried out, like the known elastic fastenings, by a flexible collar provided between the shoe and its fixing nut.
  • the lateral elastic fastening is produced, according to a preferred embodiment, by a flexible curved blade disposed between the shoe and the rail core.
  • the present invention therefore makes it possible to separate the vertical support from the horizontal support by means of two flexible fasteners which complement each other insofar as one can only exert its effects thanks to the presence of the other and vice versa, which allows the rails to retain their natural flexibility when passing the switches.
  • the curved blade of the fastening with lateral elasticity has a substantially rectangular shape with cutouts on the two opposite lateral sides to present overall the shape of an "H" whose four legs are supported on the core of the rail and whose center is supported on the shoe and is crossed by a bolt for fixing the latter to the rail.
  • the edges of the fixing shoe as well as the contact points are rounded.
  • Figures 1 and 2 show a conventional railway rail 10 comprising a mushroom 12, a vertical core 14 and a foot 16 by which the rail 10 rests by means of a sole 17, for example. made of neoprene, on a saddle 18 which is bolted at 20 onto a railway sleeper.
  • a needle (not shown) which can be moved laterally relative to the rail 10. The absence of an internal foot and the presence of the needle prevent a fixing of the rail 10 on the inner side.
  • a fixing shoe is provided as shown at 22 in Figures 1 and 2
  • This shoe 22 has a general "L" shape with a horizontal section 24 and a vertical section 26.
  • the horizontal section 24 of shoe 22 has a positioning opening 28 which, in association with a corresponding rib 30 of the saddle 18 facilitates the correct positioning of the shoe 22.
  • This shoe 22 is fixed vertically on the seat 18 using a bolt 32 and a nut 34.
  • the bolt 32 is for example retained in the saddle 18 by an enlarged head 32a which can penetrate through a keyhole opening in a hollow part of the saddle 18, or else is retained there thanks to a hammer-shaped head.
  • the vertical section 26 of the shoe 22 is supported on the core 14 of the rail 10 and is fixed there by means of a bolt 36.
  • the present invention provides for making these two fastenings elastic.
  • the vertical fixing at the level of the bolt 32 is carried out by means of a collar 38 produced in the form of a flexible tongue, the outer edge 38a of which is curved and rests on a base 40 of corresponding shape which s' pupil of the saddle 18 in the opening 28 of the shoe 22 and the opposite edge 38b of which bears elastically on the inside edge of the opening 28 of the shoe 22 under the action of tightening the nut 34.
  • This vertical elastic support is transmitted by the shoe 22 on the foot 16 of the rail 10.
  • This vertical elastic fixing is supplemented, according to the present invention, by a lateral elastic fixing which, in the example shown, is located between the shoe 26 and the core 14 of the rail 10.
  • a lateral elastic fixing which, in the example shown, is located between the shoe 26 and the core 14 of the rail 10.
  • the flexible support of the shoe 22 on the rail 10 is produced by interposition between these two elements of a curved and flexible blade 42.
  • This blade 42 has a substantially rectangular shape with two cutouts 42a, 42b on the two opposite lateral sides to define an "H" shape.
  • This blade is curved in such a way that the central region which is in contact with the shoe 26 comes out with respect to the four ends which bear on the core 14 of the rail 10.
  • the central region of the blade 42 has an opening 46 to allow passage of the bolt 36.
  • the four ends of the blade 42 are arranged and designed as a function of the shape of the core 14 of the rail so as to ensure self-positioning of the blade 42 against the rail.
  • the vertical section 26 of the shoe 22 comprises, on the face adjacent to the rail 12, two lateral stops 26a and 26b, capable of being supported on the cutouts 42a and 42b the core 14 of the rail from a certain degree of flexion of the blade 42.
  • the shape of the shoe 22 is designed to allow its assembly and disassembly without having to move or disassemble the rail.
  • the shape of the elastic elements 38 and 42 is only an exemplary embodiment and that it is possible to give other forms to these elements, provided that they perform the same functions. It is even possible to replace the collar 38 by a flexible claw which fulfills the fixing functions and which therefore makes the presence of the bolts 32 superfluous.
  • the position of the blade 42 between the shoe 26 and the rail 10 is a preferred position, it is possible to provide a fixed connection between the shoe 26 and the rail 10 and to provide a flexible support between the shoe 26 and the saddle 18, in particular at the rear edge of the opening 28. Such a flexible support would, in fact, allow the same degrees of freedom as those provided by the blade 42.
