Description

La présente invention se rapporte au domaine des appareils ferroviaires de voie et notamment des dispositifs de fixation de rails sur des traverses.The present invention relates to the field of railway track apparatus and in particular rail fastening devices on sleepers.

La fixation d'un rail sur une traverse est classiquement opérée par l'intermédiaire d'une semelle permettant, d'une part, le maintien du rail au sol et, d'autre part, le positionnement du rail selon une inclinaison particulière par rapport à la surface du sol.The fixing of a rail on a cross member is conventionally operated by means of a soleplate allowing, on the one hand, the maintenance of the rail on the ground and, on the other hand, the positioning of the rail at a particular inclination with respect to overground.

Le document US 2011/024154 propose un exemple de construction permettant la fixation d'un rail sur une traverse par l'intermédiaire d'une semelle. Le rail est maintenu fixé par son pied qui est pris en tenaille entre deux guides d'angle positionnés chacun contre un bord du pied. Ces guides d'angle sont maintenus en pression contre un bord respectif du rail grâce à des éléments de renfort fixé à la traverse par des tirefonds traversant la semelle au niveau d'alésages adaptés. Le montage des guides d'angle contre le bord du pied permet également le positionnement et le maintien d'une platine entre la face inférieure du rail et la face supérieure de la semelle, cette platine permettant d'imposer au rail un angle d'inclinaison par rapport à la verticale lors de son positionnement.The document US 2011/024154 proposes an example of construction allowing the fixing of a rail on a cross by means of a sole. The rail is held fixed by its foot which is caught between two angle guides each positioned against an edge of the foot. These angle guides are held in pressure against a respective edge of the rail with reinforcing elements attached to the cross by lag screws through the sole at appropriate bores. The mounting of the angle guides against the edge of the foot also allows the positioning and maintenance of a plate between the underside of the rail and the upper face of the sole, this plate for imposing the rail angle of inclination relative to the vertical when positioning.

Toutefois, un tel mode de réalisation comporte un nombre important de pièces différentes et donc une construction plus complexe à mettre en oeuvre qui est à l'origine d'une perte de temps conséquente lors de l'installation d'une voie ferrée ou d'un remplacement d'une portion de voie.However, such an embodiment comprises a large number of different parts and therefore a more complex construction to implement which is causing a significant loss of time during the installation of a railway or of a replacement of a portion of the track.

De plus, l'opération de réglage de la position du rail par l'intermédiaire de guides d'angle nécessite une utilisation de guides d'angle de dimensions complémentaires et adaptées. Cependant, une modification du réglage impose dès lors un changement des guides d'angle au profit d'une nouvelle paire de guides d'angle adaptée pour convenir au réglage requis. La réalisation d'une opération de réglage de la position du rail impose donc d'avoir en permanence plusieurs ensembles de guides d'angle pour obtenir un réglage affiné.In addition, the operation of adjusting the position of the rail through angle guides requires the use of angle guides of complementary and adapted dimensions. However, a modification of the setting then imposes a change of the angle guides in favor of a new pair of angle guides adapted to suit the required setting. Performing a position adjustment operation of the rail therefore requires to have several sets of angle guides permanently to obtain a refined adjustment.

Le document DE-U-29520973 propose un dispositif réalisant une semelle et des éléments de maintien sous la forme d'une pièce unique. Toutefois, là encore l'opération de réglage de la position du rail ou une modification de ces réglages nécessite également un remplacement des guides d'angle par une nouvelle paire pour répondre aux nouveaux réglages.The document DE-U-29520973 proposes a device providing a sole and holding elements in the form of a single piece. However, here again the operation of adjusting the position of the rail or a modification of these settings also requires a replacement of the angle guides by a new pair to meet the new settings.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif permettant de simplifier la pose, le positionnement, le réglage et le maintien d'un ou de plusieurs rail au niveau d'une voie ou d'un appareil de voie, tout conservant les propriétés avantageuses de fixation des dispositifs existants.The present invention aims to overcome these disadvantages by providing a device for simplifying the laying, positioning, adjustment and maintenance of one or more rails at a track or a switchgear, while retaining the advantageous properties of fixing existing devices.

L'invention a ainsi pour objet un dispositif de positionnement et de fixation d'au moins un rail sur une traverse selon la revendication 1. L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 se rapporte à une représentation schématique d'un dispositif de positionnement et de maintien selon l'invention selon une section dans un plan perpendiculaire à l'axe du rail,
  • la figure 2 se rapporte à une représentation schématique d'un dispositif de positionnement et de maintien selon l'invention selon une vue supérieure.
The invention thus relates to a device for positioning and fixing at least one rail on a cross member according to claim 1. The invention will be better understood, thanks to the following description, which relates to a method of preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which:
  • the figure 1 relates to a schematic representation of a positioning and holding device according to the invention according to a section in a plane perpendicular to the axis of the rail,
  • the figure 2 refers to a schematic representation of a positioning and holding device according to the invention in a superior view.

La présente invention se rapporte à un dispositif de positionnement et de fixation d'au moins un rail 17 sur une traverse 18 comprenant :

  • deux guides d'angle 9, 10 positionnés pour prendre le rail 17 en tenaille en appuyant contre chacun des bords axiaux du pied du rail 17,
  • une semelle 7 de positionnement sur la face supérieure de laquelle sont montés le rail 17 et les guides d'angle 9, 10, la semelle 7 étant destinée à former une interface entre la traverse 18 et les éléments montés sur la face supérieure de la semelle 7,
  • deux éléments de maintien 19, 20 positionnés de part et d'autre des guides d'angle 9, 10 pour maintenir ces guides d'angle 9, 10 en pression contre les bords du pied du rail 17,
    les éléments de maintien 19, 20 et la semelle 7 formant une seule et unique pièce.
The present invention relates to a device for positioning and fixing at least one rail 17 on a cross member 18 comprising:
  • two angle guides 9, 10 positioned to take the rail 17 in pincers by pressing against each of the axial edges of the foot of the rail 17,
  • a sole 7 of positioning on the upper face of which are mounted the rail 17 and the angle guides 9, 10, the sole 7 being intended to form an interface between the cross member 18 and the elements mounted on the upper face of the sole 7
  • two holding elements 19, 20 positioned on either side of the angle guides 9, 10 for holding these angle guides 9, 10 in pressure against the edges of the foot of the rail 17,
    the holding elements 19, 20 and the sole 7 forming a single piece.

La fixation des guides d'angle 9, 10 avec la semelle 7 peut être effectuée par l'intermédiaire d'au moins un élément de fixation 1, 2 respectif qui traverse les épaisseurs successives du guide d'angle 9, 10 et de la semelle 7 pour se fixer à la traverse 18. Selon un mode de réalisation préféré, ces éléments de fixation 1, 2 présentent à leurs extrémités, d'une part, une butée et, d'autre part, un filetage et permettent la fixation des guides d'angle 9, 10 avec la semelle 7 par une mise en pression et un serrage.The fixing of the angle guides 9, 10 with the sole 7 may be effected by means of at least one respective fastening element 1, 2 which passes through the successive thicknesses of the angle guide 9, 10 and the soleplate 7 to attach to the cross member 18. According to a preferred embodiment, these fastening elements 1, 2 have at their ends, on the one hand, a stop and, on the other hand, a thread and allow the fixing of the guides. 9, 10 with the sole 7 by pressurizing and tightening.

La fixation de la semelle 7 sur la traverse 18 peut être opérée par un ou plusieurs éléments qui traversent la structure de cette semelle 7, tels que des tire-fonds 11, 12, 13, 14. Préférentiellement, pour une fixation optimisée, ces éléments de fixation 11, 12, 13, 14 sont positionnés sur la semelle 7 de façon symétrique, par exemple aux extrémités de la semelle 7. Selon un mode de construction particulier, ces éléments de fixation 11, 12, 13, 14 sont disposés par paires sur la semelle 7 ; par exemple un élément de fixation de chaque coté du rail 17 ou encore un élément de fixation à chaque coin de la semelle 7. Selon un mode de réalisation préféré, ces éléments de fixation 11, 12, 13, 14 comportent à leurs extrémités, d'une part, une butée et, d'autre part, un filetage destiné à interagir avec la traverse 18.The attachment of the sole 7 to the crosspiece 18 may be effected by one or more elements which pass through the structure of this sole 7, such as lag bolts 11, 12, 13, 14. Preferably, for an optimized fixation, these elements 11, 12, 13, 14 are positioned on the sole 7 symmetrically, for example at the ends of the sole 7. According to a particular embodiment, these fastening elements 11, 12, 13, 14 are arranged in pairs on the sole 7; for example a fastening element on each side of the rail 17 or a fastening element at each corner of the sole 7. According to a preferred embodiment, these fastening elements 11, 12, 13, 14 comprise at their ends, on the one hand, a stop and, on the other hand, a thread intended to interact with the cross-member 18.

La réalisation d'une pièce unique réunissant la semelle 7 et les éléments de maintien 19, 20 facilite la construction du dispositif de maintien en permettant un montage simultané d'éléments pré-positionnés les uns par rapport aux autres. En effet, le montage de la semelle 7 sur la traverse 18 positionne simultanément les éléments de maintien 19, 20 du dispositif lors de sa construction.The realization of a single piece joining the sole 7 and the holding elements 19, 20 facilitates the construction of the holding device by allowing simultaneous assembly of elements pre-positioned relative to each other. Indeed, the mounting of the sole 7 on the cross 18 simultaneously positions the holding elements 19, 20 of the device during its construction.

La fabrication d'une telle pièce unique peut être effectuée par soudage des éléments de maintien 19, 20 avec la semelle 7 de positionnement.The manufacture of such a single piece can be performed by welding the holding members 19, 20 with the sole 7 positioning.

Selon une alternative de réalisation, la fabrication d'une telle pièce est réalisée par forgeage.According to an alternative embodiment, the manufacture of such a part is made by forging.

Selon une autre alternative de réalisation, la fabrication de cette pièce unique est obtenue par moulage.According to another alternative embodiment, the manufacture of this single piece is obtained by molding.

Selon un mode de construction préféré, le dispositif de positionnement et de fixation de l'invention et en particulier la pièce unique est réalisé de sorte que chacun des éléments de maintien 19, 20 est formé par une structure plane disposée dans un plan orienté, d'une part, perpendiculairement au plan de la semelle 7 de positionnement et, d'autre part, parallèlement à l'axe d'un des bords du pied de rail 17.According to a preferred embodiment, the positioning and fixing device of the invention and in particular the single piece is made so that each of the holding elements 19, 20 is formed by a flat structure disposed in an oriented plane, d 'a part, perpendicular to the plane of the soleplate 7 of positioning and, secondly, parallel to the axis of one of the edges of the rail foot 17.

D'une façon complémentaire mais non-limitative, le dispositif de positionnement et de fixation de l'invention est caractérisé en ce qu'au moins un des éléments de maintien 19, 20 comprend au moins une structure de renfort 19', 20' pour conserver l'orientation perpendiculaire de l'élément de maintien 19, 20 par rapport à la semelle 7 de positionnement, cette structure de renfort est formée par une structure plane disposée dans un plan orienté perpendiculairement, d'une part, par rapport au plan de la semelle 7 et, d'autre part, par rapport au plan de la structure de l'élément de maintien 19,20.In a complementary but nonlimiting manner, the positioning and fixing device of the invention is characterized in that at least one of the holding elements 19, 20 comprises at least one reinforcing structure 19 ', 20' for keeping the perpendicular orientation of the holding element 19, 20 relative to the positioning flange 7, this reinforcing structure is formed by a plane structure disposed in a perpendicularly oriented plane, on the one hand, with respect to the plane of the sole 7 and, secondly, with respect to the plane of the structure of the holding member 19,20.

Au niveau d'un même élément de maintien 19, 20, il peut exister une seule ou plusieurs structures de renfort 19', 20'.At the same holding member 19, 20, there may be one or more reinforcing structures 19 ', 20'.

Selon l'invention, le dispositif de positionnement et de fixation est caractérisé en ce que, sur sa face destinée à appuyer contre des guides d'angle 9, 10, au moins un des éléments de maintien 19, 20 comprend une surface d'interaction adaptée pour faciliter l'insertion de ladite cale 15, 16 entre l'élément de maintien et le guide d'angle 9, 10 correspondant. Cette surface d'interaction est réalisée par la présence de gorges ou rainures adaptées pour interagir avec un relief sur la surface correspondante de ladite cale 15, 16. Cette interaction gorge/relief permet de limiter le déplacement et donc le retrait involontaire de la cale 15, 16 du logement formé entre l'élément de maintien 19, 20 et le guide d'angle 9, 10 correspondant.According to the invention, the positioning and fixing device is characterized in that, on its face intended to bear against angle guides 9, 10, at least one of the holding elements 19, 20 comprises an interaction surface adapted to facilitate insertion of said wedge 15, 16 between the holding member and the corresponding angle guide 9, 10. This interaction surface is achieved by the presence of grooves or grooves adapted to interact with a relief on the corresponding surface of said shim 15, 16. This interaction groove / relief can limit the displacement and therefore the involuntary withdrawal of the wedge 15 , 16 of the housing formed between the holding member 19, 20 and the corresponding angle guide 9, 10.

Selon une particularité de réalisation, le dispositif de l'invention comprend une cale 15, 16 positionné entre chacun des éléments de maintien 19, 20 et un guide d'angle 9, 10 respectif. L'épaisseur des cales 15 et 16 utilisées permet le réglage du positionnement du rail en définissant la latitude de réglage.According to a particular embodiment, the device of the invention comprises a wedge 15, 16 positioned between each of the holding elements 19, 20 and a respective angle guide 9, 10. The thickness of the shims 15 and 16 used makes it possible to adjust the positioning of the rail by defining the adjustment latitude.

Selon un mode de réalisation préféré non-limitatif de l'invention, les cales 15, 16 positionnées entre chacun des éléments de maintien 19, 20 et un guide d'angle 9, 10 respectif sont interchangeables. Cette interchangeabilité participe notamment à l'utilisation de mêmes guides d'angle 9, 10 lors de l'optimisation du réglage du positionnement du rail 17. En effet, lors d'une opération de réglage, les guides d'angle 9, 10 sont conservés, seules les cales 15, 16 sont changées.According to a preferred non-limiting embodiment of the invention, the wedges 15, 16 positioned between each of the holding elements 19, 20 and a respective angle guide 9, 10 are interchangeable. This interchangeability contributes in particular to the use of the same angle guides 9, 10 when optimizing the adjustment of the positioning of the rail 17. Indeed, during a setting operation, the angle guides 9, 10 are retained, only the shims 15, 16 are changed.

Selon une particularité de réalisation, le dispositif de l'invention comprend des cales 15, 16 positionnées entre chacun des éléments de maintien 19, 20 et un guide d'angle 9, 10 respectif qui présentent des épaisseurs différentes. Cette différence d'épaisseur des cales permet ainsi d'opérer un décalage des guides d'angle 9, 10 et du rail par rapport à une position symétrique médiane du rail 17. De plus, la substitution de position des cales 15, 16 permet d'inverser le décalage des guides d'angle 9, 10 et du rail 17 par rapport à la position symétrique médiane du rail 17.According to a particular embodiment, the device of the invention comprises wedges 15, 16 positioned between each of the holding elements 19, 20 and a respective angle guide 9, 10 which have different thicknesses. This difference in the thickness of the wedges thus makes it possible to shift the angle guides 9, 10 and the rail relative to a median symmetrical position of the rail 17. In addition, the positional substitution of the wedges 15, 16 makes it possible to reversing the offset of the angle guides 9, 10 and the rail 17 relative to the median symmetrical position of the rail 17.

Selon une spécificité de cette particularité de réalisation, les cales 15, 16 positionnées entre chacun des éléments de maintien 19, 20 et un guide d'angle 9, 10 respectif présentent une différence d'épaisseur de l'ordre du millimètre. Une telle différence d'épaisseur présente la possibilité d'un réglage fin de la position des éléments de maintien 19, 20 par rapport à une position centrale du rail 17.According to a specificity of this particular embodiment, the wedges 15, 16 positioned between each of the holding elements 19, 20 and a respective angle guide 9, 10 have a difference in thickness of the order of a millimeter. Such a difference in thickness presents the possibility of a fine adjustment of the position of the holding elements 19, 20 with respect to a central position of the rail 17.

Selon une alternative à cette particularité de réalisation, le dispositif de l'invention comprend des cales 15, 16 positionnées entre chacun des éléments de maintien 19, 20 et un guide d'angle 9, 10 respectif qui présentent des épaisseurs identiques.According to an alternative to this embodiment, the device of the invention comprises shims 15, 16 positioned between each of the holding elements 19, 20 and a respective angle guide 9, 10 which have identical thicknesses.

Selon une spécificité de construction, les cales 15, 16 sont interchangeables et peuvent remplacer l'une par l'autre.According to a specific construction, the wedges 15, 16 are interchangeable and can replace one by the other.

Selon un exemple de construction non limitatif de l'invention, l'épaisseur des cales 15, 16 est comprise entre 9 et 16 millimètres.According to an exemplary non-limiting construction of the invention, the thickness of shims 15, 16 is between 9 and 16 millimeters.

La face inférieure du pied du rail 17 peut être positionnée directement contre la surface supérieure de la semelle ou bien contre une platine 8 qui permet une inclinaison de l'axe du rail 17 par rapport à la verticale.The lower face of the foot of the rail 17 can be positioned directly against the upper surface of the sole or against a plate 8 which allows an inclination of the axis of the rail 17 relative to the vertical.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention, définit par les revendications ci-jointes.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
