Abstract
Description
La présente invention concerne les supports pour détecteurs électroniques placés le long des voies ferrées pour l'actionnement des dispositifs de signalisation, et plus particulièrement une platine-support assurant à la fois le positionnement précis et la protection des détecteurs et présentant une bonne sécurité d'emploi grâce à une résistance accrue aux vibrations et aux chocs.The present invention relates to the supports for electronic detectors placed along the railways for the actuation of the signaling devices, and more particularly a support plate ensuring both the precise positioning and the protection of the detectors and having good security of use thanks to increased resistance to vibrations and shocks.
L'actionnement des dispositifs de signalisation pour le transport ferroviaire est généralement réalisé au moyen de détecteurs placés le long des voies ferrées, fixés à l'un des rails. On utilise à cet usage, soit des détecteurs électromécaniques comportant un ou deux leviers déclenchés au passage d'une circulation par le boudin de la première roue, soit des détecteurs électroniques moins lourds et dont le fonctionnement est encore statique. L'appareillage utilisé est monté sur une platine fixée de manière amovible à un support enserrant la base du rail.The actuation of signaling devices for rail transport is generally carried out by means of detectors placed along the railway tracks, fixed to one of the rails. For this use, either electromechanical detectors comprising one or two levers triggered when a circulation passes through the flange of the first wheel, or lighter electronic detectors whose operation is still static. The apparatus used is mounted on a plate detachably attached to a support enclosing the base of the rail.
La platine sur laquelle est monté le détecteur électronique doit répondre à des conditions rigoureuses en ce qui concerne les qualités mécaniques d'une part, et les qualités d'amortissement des vibrations d'autre part. En effet, pour des raisons de sécurité, il est indispensable que le fonctionnement du détecteur électronique ne soit pas perturbé par les vibrations engendrées dans les rails par le passage des trains, et il est donc nécessaire de disposer d'une platine possédant une résistance suffisante tout à la fois aux pressions de serrage dans le support de fixation sur le rail, et aux vibrations.The plate on which the electronic detector is mounted must meet rigorous conditions with regard to the mechanical qualities on the one hand, and the vibration damping qualities on the other hand. Indeed, for safety reasons, it is essential that the operation of the electronic detector is not disturbed by the vibrations generated in the rails by the passage of the trains, and it is therefore necessary to have a plate having sufficient resistance all at the same time to the clamping pressures in the fixing support on the rail, and to the vibrations.
Il est également souhaitable de disposer d'une protection efficace du détecteur contre les chocs provoqués dans l'un ou l'autre sens de circulation, par des objets traînants.It is also desirable to have effective protection of the detector against shocks caused in either direction of movement, by dragging objects.
Les platines utilisées jusqu'à présent comportent généralement deux colonnes réalisées en acier résistant aux pressions de serrage dans le support, supportant une plaque métallique portant le détecteur. Des éléments amortisseurs de vibrations sont incorporés dans cet ensemble. Un tel dispositif est généralement satisfaisant dans les conditions classiques d'utilisation, mais l'augmentation de la vitesse des trains entraine un accroissement des vibrations, qui, par leur fréquence et leur amplitude, risquent d'occasionner une rupture de la plaque métallique. De plus, la protection contre les objets traînants n'est pas assurée.The plates used until now generally have two columns made of steel resistant to clamping pressures in the support, supporting a metal plate carrying the detector. Vibration damping elements are incorporated into this assembly. Such a device is generally satisfactory under conventional conditions of use, but the increase in the speed of the trains results in an increase in vibrations, which, by their frequency and their amplitude, risk causing rupture of the metal plate. In addition, protection against dragging objects is not ensured.
Le brevet FR 2.422.146 décrit une platine servant de support à un détecteur électromécanique, montée sur deux colonnes métalliques maintenues par serrage dans une griffe fixée au rail. Le brevet FR 2.478.258 décrit également un support comprenant un plateau fixé sur deux colonnes métalliques serrées dans des mâchoires solidaires du patin du rail. Comme indiqué ci-dessus, de tels dispositifs ne donnent pas pleinement satisfaction dans des conditions d'utilisation impliquant une vitesse élevée de passage des trains.Patent FR 2,422,146 describes a plate serving as a support for an electromechanical detector, mounted on two metal columns held by clamping in a claw fixed to the rail. Patent FR 2,478,258 also describes a support comprising a plate fixed on two metal columns clamped in jaws integral with the shoe of the rail. As indicated above, such devices are not fully satisfactory under conditions of use involving a high speed of passage of trains.
Les études et essais effectués sur des pièces de fonction similaire fabriquées en diverses matières, ont montré que certaines pièces en matériau stratifié composite permettent d'éviter avec une efficacité satisfaisante la transmission au détecteur des vibrations engendrées par le rail au passage des convois, en raison des qualités propres des matériaux utilisés et des possibilités d'adapter les volumes et masses des pièces en fonction des besoins. Toutefois, les essais ont montré que des résultats satisfaisants ne pouvaient être obtenus que dans des conditions bien précises de forme et de dimensionnement de la platine.Studies and tests carried out on parts of similar function manufactured in various materials, have shown that certain parts made of composite laminate material make it possible to avoid with satisfactory efficiency the transmission to the detector of the vibrations generated by the rail as the convoys pass, because the qualities of the materials used and the possibility of adapting the volumes and masses of the parts as required. However, the tests have shown that satisfactory results could only be obtained under very precise conditions of shape and dimensioning of the plate.
La présente invention a pour objet une platine d'adaptation pour détecteur électronique évitant les inconvénients des platines usuelles rappelés ci-dessus, possédant une excellente résistance aux vibrations, et offrant une protection efficace contre les chocs.The present invention relates to an adapter plate for electronic detector avoiding the drawbacks of the usual plates mentioned above, having excellent resistance to vibration, and offering protection effective against shocks.
La platine-support conforme à la présente invention, pour détecteur placé à proximité d'un rail de voie ferrée, réalisée en un matériau stratifié composite, présente une forme de L renversé comprenant un plateau rectangulaire sensiblement perpendiculaire à une languette de maintien s'engageant dans une griffe de serrage d'un support fixé au rail, de telle sorte que la largeur de la languette est égale à environ la moitié de la longueur du plateau, la face inférieure du plateau se raccorde à la face intérieure de la languette par une surface arrondie, et le plateau déborde au-delà du plan médian de la languette sur une distance égale à 1/20 à 1/5 de sa largeur.The support plate according to the present invention, for a detector placed near a railroad track, made of a composite laminate material, has an inverted L shape comprising a rectangular plate substantially perpendicular to an engaging retaining tab. in a clamping claw of a support fixed to the rail, so that the width of the tongue is approximately half the length of the plate, the underside of the plate is connected to the inside of the tongue by a rounded surface, and the plate extends beyond the median plane of the tongue for a distance equal to 1/20 to 1/5 of its width.
Le plateau comporte deux lumières, de préférence de forme oblongue, permettant d'assurer la fixation du détecteur électronique, par exemple par simple boulonnage. Suivant une forme préférentielle de réalisation de l'invention, ces lumières servent également à la fixation d'un dispositif complémentaire de protection comprenant une lame se fixant longitudinalement au plateau, se prolongeant à chaque extrémité par un bouclier replié en forme de U. Les deux boucliers encadrent le détecteur placé sur le plateau, sans modifier sensiblement les fréquences de vibration, et le protègent contre les objets traînants éventuels au passage des convois.The tray has two lights, preferably oblong, to ensure the attachment of the electronic detector, for example by simple bolting. According to a preferred embodiment of the invention, these lights are also used for fixing an additional protective device comprising a blade which is fixed longitudinally to the plate, extended at each end by a shield folded in a U-shape. The two shields frame the detector placed on the platform, without appreciably modifying the vibration frequencies, and protect it from any trailing objects when passing convoys.
Comme indiqué ci-dessus, le plateau de la platine-support déborde au-delà du plan médian de la languette sur une distance comprise entre 1/20 et 1/5 de sa largeur; de plus, la surface de raccordement du plateau à la languette est continue et ne présente aucun décrochement. Les essais effectués ont montré que cette disposition, combinée à l'utilisation du matériau composite stratifié, permettait d'amortir efficacement les vibrations du plateau engendrées par le passage d'un convoi. Par ailleurs, le choix des fibres de renforcement incorporées dans la matière permet de modifier les caractéristiques mécaniques de la platine sans nuire à ses qualités d'amortissement des vibrations.As indicated above, the plate of the support plate projects beyond the median plane of the tongue over a distance between 1/20 and 1/5 of its width; moreover, the connection surface of the plate to the tongue is continuous and does not show any dropout. The tests carried out have shown that this arrangement, combined with the use of the laminated composite material, makes it possible to effectively dampen the vibrations of the plate generated. by the passage of a convoy. Furthermore, the choice of reinforcing fibers incorporated in the material makes it possible to modify the mechanical characteristics of the plate without harming its qualities of damping vibrations.
La platine est réalisée suivant les techniques usuelles, par moulage à partir d'une composition qui peut être par exemple une composition à base de fibres de verre, de carbone et d'aramid, noyées dans une résine de type polyester, époxyde, ester vinylique ou une résine phénolique. Le choix des fibres de renforcement est déterminé de manière connue en fonction des caractéristiques mécaniques recherchées.The platinum is produced according to the usual techniques, by molding from a composition which may for example be a composition based on glass fibers, carbon and aramid, embedded in a resin of polyester, epoxy, vinyl ester type. or a phenolic resin. The choice of reinforcing fibers is determined in a known manner according to the mechanical characteristics sought.
Suivant une caractéristique de l'invention, la surface du plateau de la platine-support est parallèle au plan de roulement sur les rails de la voie ferrée. La platine étant fixée au rail par l'intermédiaire d'un support enserrant le patin du rail, et celui-ci présentant généralement une pente de 1/20 par rapport au plan de roulement, il est avantageux de compenser cette pente, par exemple en utilisant une platine où le plateau, dont l'épaisseur est constante, forme un angle avec la languette légèrement inférieur à 90° (par exemple 87°) pour compenser l'inclinaison du rail. Suivant une variante, la face inférieure du plateau est exactement perpendiculaire à la languette mais la face supérieure est inclinée suivant une pente de 1/20 opposée à celle du rail. Il est également possible de prévoir une griffe de serrage de la languette compensant directement cette inclinaison.According to a characteristic of the invention, the surface of the plate of the support plate is parallel to the running plane on the rails of the railroad track. The plate being fixed to the rail by means of a support enclosing the shoe of the rail, and the latter generally having a slope of 1/20 relative to the running surface, it is advantageous to compensate for this slope, for example by using a plate where the plate, the thickness of which is constant, forms an angle with the tongue slightly less than 90 ° (for example 87 °) to compensate for the inclination of the rail. According to a variant, the lower face of the plate is exactly perpendicular to the tongue but the upper face is inclined according to a slope of 1/20 opposite to that of the rail. It is also possible to provide a clamp for gripping the tongue directly compensating for this inclination.
La platine est fixée par sa languette dans la griffe de serrage d'un support se fixant sur le patin du rail par emboi- tement de deux mors. Le serrage et le blocage des mors s'effectuent par vis et aplatissement contrôlé de rondelles ressorts de type Belleville.The plate is fixed by its tongue in the clamping claw of a support fixing on the rail pad by interlocking two jaws. Clamping and locking of the jaws is effected by screws and controlled flattening of Belleville type spring washers.
Les essais effectués au moyen de la platine-support conforme à la présente invention ont montré que les caractéristiques ci-dessus permettaient d'obtenir une fréquence de résonnance de la platine située entre 35 et 60Hz, c'est-à-dire en dehors des fréquences de résonnance du rail (80 à 120Hz) et de ses harmoniques (5 à 30Hz). Au contraire, des platines réalisées dans une même matière, mais présentant une forme quelque peu modifiée, notamment au raccordement du plateau et de la languette, ne procurent pas de résultats satisfaisants.The tests carried out by means of the support plate in accordance with the present invention have shown that the characteristics above made it possible to obtain a resonance frequency of the turntable located between 35 and 60Hz, that is to say outside the resonance frequencies of the rail (80 to 120Hz) and its harmonics (5 to 30Hz). On the contrary, plates made of the same material, but having a somewhat modified shape, in particular at the connection of the plate and the tongue, do not provide satisfactory results.
La platine-support conforme à l'invention s'avère donc avantageuse pour le montage de détecteurs électroniques le long des voies ferrées en procurant une fiabilité accrue par rapport aux matériels usuels. De plus, le coût de sa fabrication est faible.The support plate according to the invention therefore proves to be advantageous for the mounting of electronic detectors along the railways while providing increased reliability compared to conventional equipment. In addition, the cost of its manufacture is low.

La platine représentée sur les figures 1 et 2 est réalisée en un matériau stratifié composite fabriqué par moulage et, présentant la forme d'un L renversé. Elle comporte une languette de maintien (1) destinée à être mise en place et fixée par serrage à hauteur voulue dans une griffe d'un support de fixation au rail (non représenté) de type approprié, permettant de régler librement la bauteur de la platine par rapport au rail, et un plateau horizontal (2) parallèle au plan de roulement, et muni de deux lumières (3) de forme oblongue, permettant le montage du détecteur électronique et la fixation du dispositif de protection.The plate shown in Figures 1 and 2 is made of a composite laminate material produced by molding and, having the shape of an inverted L. It comprises a retaining tab (1) intended to be put in place and fixed by clamping at the desired height in a claw of a support for fixing to the rail (not shown) of the appropriate type, allowing to freely adjust the height of the plate relative to the rail, and a horizontal plate (2) parallel to the running plane, and provided with two oblong lights (3), allowing the mounting of the electronic detector and the fixing of the device protection.
La hauteur de la languette de maintien (2) est de 140mm environ, sa largeur de 60mm environ et son épaisseur de 8,5mm environ. Cette languette est maintenue par serrage à hauteur appropriée dans une griffe solidaire d'un support métallique qui se fixe sur le patin du rail par emboîtement de deux mors. La hauteur de la platine est réglée de telle sorte que la surface du détecteur, dont l'épaisseur est d'environ 50mm, soit à 40mm environ en dessous du plan de roulement.The height of the retaining tab (2) is approximately 140mm, its width approximately 60mm and its thickness approximately 8.5mm. This tongue is held by clamping at an appropriate height in a claw secured to a metal support which is fixed on the shoe of the rail by fitting two jaws. The height of the plate is adjusted so that the surface of the detector, whose thickness is approximately 50mm, is approximately 40mm below the running surface.
Le plateau (2) est de forme rectangulaire de 160mm de longueur et 80mm de largeur environ. Les lumières (3) ont une forme oblongue de 30mm de longueur environ afin de permettre un réglage précis de la position d'un détecteur par rapport au rail. L'angle du plateau (2) avec la languette (1) est d'environ 87°, et son épaisseur est d'environ 12mm, mais suivant une variante non représentée, elle peut varier progressivement suivant la largeur, de 8mm environ au bord à 12mm du côté du rattachement à la languette ce qui permet de rattraper l'inclinaison au 1/20 du patin du rail, et par suite de la languette de maintien (1) qui lui est attachée, et de placer la surface du plateau (2) dans un plan horizontal.The tray (2) is rectangular, 160mm long and 80mm wide. The lights (3) have an oblong shape of approximately 30mm in length in order to allow precise adjustment of the position of a detector relative to the rail. The angle of the plate (2) with the tongue (1) is about 87 °, and its thickness is about 12mm, but according to a variant not shown, it can vary gradually depending on the width, from about 8mm to the edge 12mm from the side of the attachment to the tongue which makes it possible to make up for the 1/20 inclination of the shoe of the rail, and therefore the holding tab (1) which is attached to it, and to place the surface of the plate ( 2) in a horizontal plane.
Pour procurer un amortissement satisfaisant des vibrations engendrées dans le rail par le passage des trains, il importe que les dimensions de la languette (1) et du plateau (2) soient dans les proportions des valeurs indiquées ci-dessus, que le plan moyen de la languette (1) passe à environ 10mm du bord intérieur du plateau (2) qui déborde d'environ 6mm au delà de la surface extérieure (4) de la languette (1), et que la surface reliant le bord à la languette ne présente pas de rupture. D'autre part, la surface inférieure du plateau (2) et la surface intérieure (5) de la languette (1) se rejoignent suivant un arrondi correspondant à un rayon de 20mm environ.To provide satisfactory damping of the vibrations generated in the rail by the passage of the trains, it is important that the dimensions of the tongue (1) and of the plate (2) are in the proportions of the values indicated above, that the mean plane of the tongue (1) passes about 10mm from the inner edge of the plate (2) which projects about 6mm beyond the outer surface (4) of the tongue (1), and that the surface connecting the edge to the tongue does not presents no rupture. On the other hand, the lower surface of the plate (2) and the inner surface (5) of the tongue (1) meet in a rounded shape corresponding to a radius of about 20mm.
Comme le montrent les figures 3 et 4, le dispositif de protection comporte une lame (6) aux extrémités de laquelle sont fixés deux boucliers repliés (7) en forme de U vers le plateau (2). La hauteur de ces boucliers (7) correspond sensiblement à l'épaisseur du détecteur (non représenté) qui se fixe sur la plateau (2) au moyen des tiges filetées (8) qui servent également à la fixation du dispositif de protection.As shown in Figures 3 and 4, the protective device comprises a blade (6) at the ends of which are fixed two folded shields (7) U-shaped towards the plate (2). The height of these shields (7) corresponds substantially to the thickness of the detector (not shown) which is fixed on the plate (2) by means of the threaded rods (8) which also serve for fixing the protection device.
Le dispositif de protection est réalisé par moulage au moyen du même matériau stratifié composite que la platine.The protection device is produced by molding using the same composite laminate material as the plate.
