Description
Système de fixation d'une contre-aiguille sur une structure de support System for fixing a counter-needle on a support structure
La présente invention se rapporte au domaine du montage et de la fixation d'un appareil de voie sur une traverse ou un radier et plus particulièrement au montage et à la fixation d'une contre-aiguille. The present invention relates to the field of mounting and fixing a track apparatus on a cross or a raft and more particularly to mounting and fixing a counter-needle.
Actuellement, le montage d'un appareil de voie au niveau d'une traverse particulière ou directement sur un radier béton est opéré par l'intermédiaire notamment d'une structure de support. Au niveau d'un aiguillage, cette structure de support forme une interface entre les rails de l'appareil de voie et la traverse ou le radier béton. Currently, the mounting of a switchgear at a particular cross or directly on a concrete slab is operated through including a support structure. At a switch, this support structure forms an interface between the rails of the switchgear and the crossbar or the concrete raft.
A l'heure actuelle, le montage et la fixation d'une contre - aiguille d'appareil de voie sur cette structure de support est effectuée par une coopération d'élément de fixation de chaque coté de la face supérieure du patin de la contre-aiguille. Un premier élément de fixation est classiquement réalisé par un ressort mis en pression sur le coté de la contre- aiguille par une pièce de serrage. Un second élément de fixation est réalisé par un élément de blocage qui cercle le coussinet de glissement de l'aiguille et se positionne, en partie, entre la surface supérieure du patin et le coussinet de glissement. At the present time, the mounting and securing of a tailpiece counter-needle to this support structure is effected by a fastener element cooperation on each side of the upper face of the counter skid. needle. A first fastener is conventionally made by a spring pressurized on the side of the counter-needle by a clamping piece. A second attachment member is provided by a locking member which circles the needle sliding pad and is positioned, in part, between the upper surface of the pad and the sliding pad.
Toutefois, un tel élément de blocage, au niveau du coussinet de glissement, est particulièrement exposé aux projections, aux chocs, etc. Une telle construction conduit inévitablement à un risque accru de casse de l'élément de blocage et donc à une désolidarisation de la contre-aiguille de son support au niveau de l'appareil de voie. However, such a locking element at the sliding bearing is particularly exposed to projections, shocks, etc. Such a construction inevitably leads to an increased risk of breakage of the blocking element and thus to a separation of the counter-needle from its support at the level of the switchgear.
Par ailleurs, de façon courante, la construction d'un tel mécanisme de fixation de contre-aiguille est opérée par un assemblage mécano-soudé. Un tel assemblage a comme principal défaut d'être à l'origine de problèmes de tenu de rail et d'apparition d'écartement de voie. Furthermore, currently, the construction of such a counter-needle fixing mechanism is operated by a welded joint. Such an assembly has as its main defect to be at the origin of problems of rail held and appearance of track gauge.
La présente invention a pour but de pallier ces inconvénients en proposant un système de fixation d'une contre-aiguille d'un appareil de voie sur une structure de support permettant de limiter, voire supprimer les risques de casse, tout en optimisant la production et le montage de ce système. The object of the present invention is to overcome these drawbacks by proposing a system for attaching a counter-needle of a switchgear to a support structure making it possible to limit or even eliminate the risks of breakage, while optimizing the production and the assembly of this system.

- un élément de blocage de la contre-aiguille destiné à être inséré dans le logement et comportant une partie positionnée sous la portion en porte-à-faux de la structure de support et en appuie, d'une part, contre la face inférieure de la portion en porte-à-faux, et d'autre part, contre la face supérieure du patin de la contre-aiguille. a locking element of the counter-needle intended to be inserted into the housing and comprising a part positioned under the cantilevered portion of the support structure and bears against the lower face of the support structure; the cantilevered portion, and secondly, against the upper face of the shoe of the counter-needle.
L'invention porte également sur un procédé de production d'un système de fixation d'un appareil de voie selon l'invention, caractérisé en ce qu'il comprend au moins une étape de moulage de la structure de support et notamment de la seconde partie comportant également un logement. The invention also relates to a method for producing a fastening system for a switchgear according to the invention, characterized in that it comprises at least one step of molding the support structure and in particular the second part also comprising a dwelling.
L'invention sera mieux comprise, grâce à la description ci- après, qui se rapporte à au moins un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels : The invention will be better understood, thanks to the following description, which relates to at least one preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:

- la figure 2 est la représentation schématique d'une vue supérieure d'un système de fixation d'une contre-aiguille selon l'invention. - Figure 2 is a schematic representation of a top view of a fastening system of a counter-needle according to the invention.
L'invention se rapporte à un système de fixation d'une contre- aiguille lb d'un appareil de voie 1 pour voie ferroviaire sur une structure de support 3 destiné à être montée sur une traverse 2 ou directement sur un radier, caractérisé en ce que ce système comprend au moins : The invention relates to a system for fastening a counter-needle lb of a railroad track apparatus 1 to a support structure 3 intended to be mounted on a cross-member 2 or directly on a raft, characterized in that that this system includes at least:
- une structure de support 3 réalisée en deux parties avec, d'une part, une première partie 3a formant une surface sur laquelle est positionné le patin de la contre-aiguille lb et, d'autre part, une seconde partie 3b
comportant une portion 3c positionnée en porte-à-faux au dessus de la première partie 3 a de la structure de support 3, la seconde partie 3b comportant également un logement 4 dont un orifice 4b débouche au niveau de la première partie 3a au dessous de la portion 3c en porte-à-faux, a support structure 3 made in two parts with, on the one hand, a first part 3a forming a surface on which is positioned the pad of the counter-needle lb and, on the other hand, a second part 3b having a portion 3c positioned cantilevered above the first portion 3a of the support structure 3, the second portion 3b also having a housing 4, a port 4b opens at the first portion 3a below portion 3c cantilevered,
- une contre-aiguille lb d'un appareil de voie 1 dont au moins un bord du patin est positionné sous la portion 3c en porte-à-faux de la seconde partie 3b de la structure de support 3, a counter-needle lb of a track apparatus 1 of which at least one edge of the pad is positioned under the cantilever portion 3c of the second part 3b of the support structure 3,
- un élément de blocage 5 de la contre-aiguille lb destiné à être inséré dans le logement 4 et comportant une partie 5a positionnée sous la portion 3c en porte-à-faux de la structure de support 3 et en appuie, d'une part, contre la face inférieure de la portion 3c en porte-à-faux, et d'autre part, contre la face supérieure du patin de la contre-aiguille lb. a locking element 5 of the counter-needle 1b intended to be inserted in the housing 4 and comprising a part 5a positioned under the cantilevered portion 3c of the support structure 3 and bears on the one hand; against the underside of the portion 3c cantilever, and secondly, against the upper face of the shoe against the needle lb.
L'appuie contre la face supérieure du patin de la contre-aiguille lb permet ainsi une limitation du déplacement vertical de la contre-aiguille lb. Pressing against the upper face of the shoe of the counter-needle lb thus allows a limitation of the vertical displacement of the counter-needle lb.
Selon une alternative de réalisation, le montage de la structure de support 3 sur la traverse 2 ou le radier est opéré par une semelle intermédiaire amortissante positionné entre la structure de support 3 et la traverse 2 ou le radier. According to an alternative embodiment, the mounting of the support structure 3 on the cross member 2 or the raft is operated by a damping midsole positioned between the support structure 3 and the crossbar 2 or the raft.
Le système de fixation de la contre-aiguille lb s'appuie en partie sur un élément de blocage 5 positionné dans un logement 4 adapté, de sorte que son exposition à des agressions extérieures se trouve réduite. Ainsi, seule la partie 5a de l'élément de blocage 5 destinée à interagir avec la face supérieure du patin de la contre-aiguille lb se trouve extériorisé. Le logement 4 de la seconde partie 3b de la structure de support 3 participe à la protection de l'élément de blocage 5. The securing system of the counter-needle lb relies in part on a locking element 5 positioned in a housing 4 adapted, so that its exposure to external aggressions is reduced. Thus, only the portion 5a of the blocking element 5 intended to interact with the upper face of the shoe of the counter-needle lb is externalized. The housing 4 of the second part 3b of the support structure 3 contributes to the protection of the locking element 5.
Selon une particularité de réalisation, l'extrémité du logement 4 est prolongée dans la portion 3c en porte-à-faux, de sorte que l'extrémité 5a de l'élément de blocage 5 positionné dans le logement 4, est disposée dans le prolongement de la face inférieure de l'extrémité de la portion 3c en porte-à-faux. Selon cette particularité de réalisation, la portion 3c en porte - à-faux qui surplombe la première partie 3 a de la structure de support 3, comprend une partie dans laquelle est positionnée une extrémité du logement 4. L'extrémité de la portion 3c en porte-à-faux comprend ainsi, au niveau du bord de la portion 3c, une face inférieure qui participe au positionnement du patin de la contre-aiguille lb. Plus en profondeur, décalé latéralement par rapport au bord de la portion 3c, l'extrémité du logement 4
se trouve positionné de sorte que, une fois en position dans le logement 4, l'élément de blocage 5 présente une face inférieure disposée dans le prolongement de la face inférieure de l'extrémité de la portion 3c en porte- à-faux. According to a particular embodiment, the end of the housing 4 is extended in the portion 3c cantilever, so that the end 5a of the locking element 5 positioned in the housing 4, is arranged in the extension the lower face of the end of the portion 3c cantilever. According to this embodiment, the cantilevered portion 3c which overhangs the first part 3a of the support structure 3, comprises a part in which is positioned an end of the housing 4. The end of the portion 3c in cantilever thus comprises, at the edge of the portion 3c, a lower face which participates in the positioning of the shoe against the needle lb. More deeply, laterally offset from the edge of the portion 3c, the end of the housing 4 is positioned so that, once in position in the housing 4, the locking member 5 has a lower face disposed in the extension of the underside of the end of the portion 3c cantilever.
Selon un mode de réalisation préféré mais non-limitatif de l'invention, la fixation de la contre-aiguille fait également intervenir une nervure 6, au niveau de la première partie 3a de la structure de support 3, et contre laquelle est positionné le bord du patin de la contre-aiguille lb qui n'est pas situé sous la portion 3c en porte-à-faux de la structure de support 3. Cette nervure 6 présente également comme avantage de faciliter le positionnement du patin de la contre-aiguille lb sur la structure de support 3 selon une disposition optimisée, voire préférée. Par ailleurs, la nervure 6 permet également de limiter le déplacement de la contre-aiguille lb, le bord du patin de celle-ci venant alors en butée contre la nervure 6. According to a preferred but non-limiting embodiment of the invention, the attachment of the counter-needle also involves a rib 6, at the first part 3a of the support structure 3, and against which is positioned the edge the counter-needle lug lb which is not located under the cantilevered portion 3c of the support structure 3. This rib 6 also has the advantage of facilitating the positioning of the lug of the counter-needle 1b on the support structure 3 in an optimized arrangement, or even preferred. Moreover, the rib 6 also makes it possible to limit the displacement of the counter-needle 1b, the edge of the pad thereof then coming into abutment against the rib 6.
Selon un complément de réalisation à ce mode préféré, la fixation fait intervenir une attache 7 de rail montée sur la nervure 6 et adaptée pour exercer une pression contre la face supérieure du patin de la contre-aiguille lb disposée du coté de la nervure 6. Ainsi, la nervure 6 forme une structure de positionnement de l'attache 7 de rail. Selon un exemple de réalisation, cette attache 7 de rail peut être formée par une pièce de serrage qui appuie sur la face supérieure du patin de la contre-aiguille lb par l'intermédiaire d'un ressort. La pièce de serrage de l'attache 7 du rail se trouve ainsi montée sur la structure de support 3 au niveau de la nervure 6. Lorsque la pièce de serrage est formée par un tire-fond, cette attache 7 du rail est fixée à la structure de support 3 au niveau d'un alésage de la nervure 6. According to a further embodiment of this preferred embodiment, the attachment involves a rail fastener 7 mounted on the rib 6 and adapted to exert pressure against the upper face of the shoe of the counter-needle lb disposed on the side of the rib 6. Thus, the rib 6 forms a positioning structure of the rail fastener 7. According to an exemplary embodiment, this rail fastener 7 may be formed by a clamping piece which bears against the upper face of the shoe of the counter-needle 1b by means of a spring. The fastening piece of the fastener 7 of the rail is thus mounted on the support structure 3 at the rib 6. When the clamping piece is formed by a lag bolt, this fastener 7 of the rail is fixed to the support structure 3 at a bore of the rib 6.
Selon un autre mode de réalisation préféré de l'invention, complémentaire au mode de réalisation précédemment évoqué, le système de fixation de la contre-aiguille lb est caractérisé en ce que la face supérieure de la seconde partie 3b de la structure de support 3 forme un coussinet de glissement 8 sur la surface duquel l'aiguille la de l'appareil de voie 1 se déplace. Ainsi, le logement 4 est disposé dans la seconde partie 3b, sous la surface de glissement de l'aiguille la formée par le coussinet 8. According to another preferred embodiment of the invention, complementary to the embodiment mentioned above, the fastening system of the counter-needle lb is characterized in that the upper face of the second part 3b of the support structure 3 forms a sliding pad 8 on the surface of which the needle 1a of the track apparatus 1 moves. Thus, the housing 4 is disposed in the second part 3b, under the sliding surface of the needle 1a formed by the pad 8.
Selon un exemple de mise en application de l'invention, la surface du coussinet 8 de glissement peut être revêtue d'un traitement de type Nickel-Chrome, voire de Molybdène, qui facilite la résistance à l'oxydation et y optimise le glissement de l'aiguille la.
Selon une particularité non-limitative de l'invention, le logement 4 pour l'élément de blocage 5 comporte un orifice d'insertion 4a positionné du coté de la seconde partie 3b de la structure de support 3 situé du coté opposé à la première partie 3b. Cette orifice d'insertion 4a permet le positionnement de l'élément de blocage 5 dans le logement 4 depuis le coté de la structure de support 3 qui ne porte pas la contre-aiguille lb. Cet orifice d'insertion 4a permet ainsi un positionnement de l'élément de blocage 5 sans être gêné par la contre-aiguille lb. According to an exemplary implementation of the invention, the surface of the sliding pad 8 can be coated with a nickel-chromium type treatment, or even molybdenum, which facilitates the resistance to oxidation and optimizes the sliding of the needle la. According to a non-limiting feature of the invention, the housing 4 for the blocking element 5 comprises an insertion orifice 4a positioned on the side of the second part 3b of the support structure 3 located on the opposite side to the first part. 3b. This insertion hole 4a allows the positioning of the locking element 5 in the housing 4 from the side of the support structure 3 which does not bear the needle against lb. This insertion hole 4a thus allows positioning of the locking element 5 without being disturbed by the counter-needle 1b.
Selon un particularité préféré de réalisation, l'orifice d'insertion 4a comporte une butée 4a' contre laquelle l'extrémité 5b de l'élément de blocage 5 qui est opposée à l'extrémité 5a en appui contre le patin de la contre-aiguille lb, est en appui transversalement, par rapport à l'axe de la contre-aiguille, pour éviter un déplacement accidentel de l'élément de blocage 5 dans le logement 4. According to a preferred embodiment, the insertion orifice 4a has a stop 4a 'against which the end 5b of the locking element 5 which is opposite the end 5a bears against the shoe of the counter-needle lb, is supported transversely, relative to the axis of the counter-needle, to prevent accidental movement of the locking element 5 in the housing 4.
Selon une particularité de réalisation, l'élément de blocage 5 de la contre-aiguille lb est réalisé sous la forme d'une pièce supportant une flexion permettant son insertion et son ancrage réversible dans le logement According to a particular embodiment, the blocking element 5 of the counter-needle lb is made in the form of a part supporting a flexion allowing its insertion and its reversible anchoring in the housing
4 de la seconde partie 3b de la structure de support 3. L'élément de blocage4 of the second part 3b of the support structure 3. The blocking element
5 est produit de façon à pouvoir supporter une contrainte en flexion. La résistance à cette contrainte en flexion permet à l'élément de blocage 5, d'une part, d'être inséré, positionné et ancré facilement dans le logement 4 de la structure de support 3 et, d'autre part, de faciliter la génération d'une pression sur la face supérieure du patin de la contre-aiguille lb. 5 is produced so as to be able to withstand a bending stress. The resistance to this bending stress allows the blocking element 5, on the one hand, to be inserted, positioned and anchored easily in the housing 4 of the support structure 3 and, on the other hand, to facilitate the generating a pressure on the upper face of the shoe of the counter needle lb.
Selon un mode de réalisation préféré non-limitatif de l'invention, l'élément de blocage 5 est réalisé par une structure mise en flexion entre, d'une part, à chacune de ses extrémités par la face supérieure de la contre-aiguille lb et un relief sur la face inférieure du logement 4 et, d'autre part, un relief 4c de la surface supérieure du logement 4. Ainsi, la résistance à la flexion de l'élément de blocage 5 permet de profiter d'un arrangement et d'une construction particulière du logement 4 pour fixer la contre-aiguille lb en position sur la structure de support 3. According to a preferred non-limiting embodiment of the invention, the blocking element 5 is made by a structure placed in bending between, on the one hand, at each of its ends by the upper face of the counter needle lb and a relief on the lower face of the housing 4 and, on the other hand, a relief 4c of the upper surface of the housing 4. Thus, the bending strength of the locking element 5 allows to take advantage of an arrangement and of a particular construction of the housing 4 for fixing the counter-needle lb in position on the support structure 3.
