Description

La présente invention concerne un aiguillage du comprenant deux rails fixes et au moins un rail d'aiguille mobile, ledit aiguillage comprenant en outre un dispositif de commande de l'aiguillage commandant le déplacement du rail d'aiguille, ledit dispositif comprenant :

  • des moyens de commande électriques dudit aiguillage,
  • des moyens de commande manuels dudit aiguillage,
  • des moyens d'actionnement dudit aiguillage, lesdits moyens d'actionnement reliant les moyens de commande électriques et manuels entre eux et au rail d'aiguille de sorte à transmettre la commande de déplacement du rail d'aiguille des moyens de commande audit rail d'aiguille.
The present invention relates to a switch comprising two fixed rails and at least one movable needle rail, said switch further comprising a switch control device controlling the movement of the needle rail, said device comprising:
  • electrical control means of said switch,
  • manual control means of said switch,
  • means for actuating said switch, said actuating means connecting the electrical and manual control means to each other and to the needle rail so as to transmit the movement control of the needle rail of the control means to said rail; needle.

On connaît de tels aiguillages dans lesquels le dispositif de commande est disposé le long d'un des rails fixes de sorte à être accessible pendant que des véhicules ferroviaires circulent sur la voie. En effet, l'accès à l'espace entre les rails est interdit lorsque des véhicules circulent sur la voie pour des raisons de sécurité.Such switches are known in which the control device is arranged along one of the fixed rails so as to be accessible while railway vehicles are traveling on the track. Indeed, access to the space between the rails is prohibited when vehicles are traveling on the track for security reasons.

Le dispositif de commande regroupe des moyens de commande électriques et des moyens de commande manuels, ce qui le rend encombrant. Il faut donc disposer d'un grand espace sur le côté des rails pour permettre l'installation du dispositif de commande.The control device includes electrical control means and manual control means, which makes it bulky. It is therefore necessary to have a large space on the side of the rails to allow the installation of the control device.

Lorsque l'on souhaite installer un aiguillage sur une voie prévue dans un tunnel, par exemple une voie souterraine, on prévoit de creuser une niche dans la paroi du tunnel afin de dégager l'espace nécessaire pour l'installation et l'utilisation du dispositif de commande sur le côté d'un rail fixe. L'installation est donc peu pratique et nécessite des aménagements importants dans le tunnel, ce qui peut entraîner un blocage de la voie pendant un temps prolongé.When it is desired to install a switch on a planned lane in a tunnel, for example an underground lane, it is planned to dig a niche in the tunnel wall in order to make room for the installation and use of the device. on the side of a fixed rail. The installation is therefore impractical and requires significant adjustments in the tunnel, which can cause a blockage of the track for an extended period.

L'un des buts de l'invention est de pallier ces inconvénients en proposant un aiguillage offrant un encombrement réduit et ne nécessitant pas de disposer d'un espace important sur le côté d'un des rails fixes.One of the aims of the invention is to overcome these disadvantages by proposing a switch offering a small footprint and does not require to have a large space on the side of one of the fixed rails.

A cet effet, l'invention concerne un aiguillage du type précité, dans lequel les moyens de commande électriques sont regroupés au sein d'un boîtier disposé entre les rails fixes et les moyens de commande manuels sont séparés dudit boîtier et disposés à l'extérieur de l'espace s'étendant entre lesdits rails fixes.For this purpose, the invention relates to a switch of the aforementioned type, wherein the electrical control means are grouped within a housing disposed between the fixed rails and the manual control means are separated from said housing and disposed outside. space extending between said fixed rails.

Ainsi, les moyens de commande électriques ne sont pas disposés sur le côté d'un rail fixe, ce qui réduit l'espace nécessaire à l'installation du dispositif, tandis que les moyens de commande manuels, peu encombrants, sont disposés en dehors des rails fixes pour permettre d'y accéder et de les manoeuvrer même lorsque des véhicules ferroviaires circulent sur les rails. L'installation d'un tel aiguillage dans un tunnel ne nécessite pas de creuser une niche dans la paroi du tunnel du fait de son faible encombrement.Thus, the electrical control means are not arranged on the side of a fixed rail, which reduces the space required for the installation of the device, while the manual control means, compact, are arranged outside the fixed rails to allow access and maneuvering even when rail vehicles run on rails. The installation of such a switch in a tunnel does not require digging a recess in the wall of the tunnel because of its small size.

Dans la description, les termes « amont » et « aval » sont définis par rapport à la direction de circulation d'un véhicule ferroviaire sur les rails. Le terme « longitudinal » est défini selon la direction dans laquelle s'étendent les rails et le terme « transversal » est défini selon une direction horizontale perpendiculaire à la direction longitudinale.In the description, the terms "upstream" and "downstream" are defined relative to the direction of movement of a railway vehicle on the rails. The term "longitudinal" is defined in the direction in which the rails extend and the term "transverse" is defined in a horizontal direction perpendicular to the longitudinal direction.

En référence à la Fig. 1, on décrit un aiguillage 1 comprenant généralement deux rails fixes 2 et 4 et au moins un rail d'aiguille 6 mobile selon une direction sensiblement transversale. Selon le mode de réalisation représenté sur la Fig. 1, l'aiguillage 1 comprend deux rails d'aiguille 6 mobiles solidaires en déplacement.With reference to the Fig. 1 , a switch 1 generally comprising two fixed rails 2 and 4 and at least one movable needle rail 6 in one direction is described. substantially transverse. According to the embodiment shown on the Fig. 1 , the switch 1 comprises two movable moving needle rails 6 movable.

Le déplacement des rails d'aiguille 6 est commandé par un dispositif de commande comprenant des moyens de commande électriques 8, des moyens de commande manuels 10 et des moyens d'actionnement 12, reliant les moyens de commande électriques et manuels aux rails d'aiguille 6 de sorte à transmettre la commande de déplacement du rail d'aiguille.The displacement of the needle rails 6 is controlled by a control device comprising electrical control means 8, manual control means 10 and actuating means 12, connecting the electrical and manual control means to the needle rails 6 so as to transmit the movement control of the needle rail.

Les moyens de commande électriques 8 sont regroupés dans un boîtier 14, comme représenté sur la Fig. 2. Ce boîtier 14 est disposé entre les rails fixes 2 et 4 et est fixé sur une ou plusieurs traverses 16 en amont des rails d'aiguille 6.The electrical control means 8 are grouped together in a housing 14, as shown in FIG. Fig. 2 . This housing 14 is disposed between the fixed rails 2 and 4 and is fixed on one or more crosspieces 16 upstream of the needle rails 6.

Les moyens de commande électriques 8 comprennent un moteur d'entraînement (non représenté) alimenté en électricité et apte à entraîner, en sortie 17, le déplacement des moyens d'actionnement 12 afin de déplacer les rails d'aiguille 6. Les moyens d'actionnement électriques ne seront pas décrits en détail ici et sont par exemple similaires au dispositif décrit dans le document FR-2 896 752 .The electrical control means 8 comprise a drive motor (not shown) supplied with electricity and adapted to drive, at the outlet 17, the displacement of the actuating means 12 in order to move the needle rails 6. The means of electrical actuations will not be described in detail here and are for example similar to the device described in the document FR-2,896,752 .

Les moyens de commande électriques sont recouverts par une plaque de protection 18 protégeant le boîtier 14 des pièces susceptibles de faire saillie d'un véhicule ferroviaire circulant sur les rails 2 et 4.The electrical control means are covered by a protective plate 18 protecting the housing 14 of the parts likely to protrude from a railway vehicle traveling on the rails 2 and 4.

Les moyens de commande manuels 10 sont disposés en dehors des rails fixes 2 et 4, c'est-à-dire en dehors de l'espace s'étendant entre ces rails. Les moyens de commande manuels 10 sont par exemple fixés sur la traverse 16, sur un côté d'un des rails fixes de sorte à pouvoir être actionnés sans accéder à l'espace s'étendant entre les rails fixes.The manual control means 10 are arranged outside the fixed rails 2 and 4, that is to say outside the space extending between these rails. The manual control means 10 are for example fixed on the crossmember 16, on one side of one of the fixed rails so as to be operable without access to the space extending between the fixed rails.

Les moyens de commande manuels comprennent un levier 20 mobile en rotation autour d'un axe sensiblement transversal et entraînant la rotation d'une tringle 22 reliant le levier 20 aux moyens de commande électriques 8. La tringle 22 passe sous le rail fixe 2 et s'étend sensiblement transversalement. La rotation du levier 20 permet d'entraîner les moyens d'actionnement 12 lorsqu'une commande manuelle du déplacement des rails d'aiguille est sélectionnée, comme décrit ultérieurement.The manual control means comprise a lever 20 movable in rotation about a substantially transverse axis and causing the rotation of a rod 22 connecting the lever 20 to the electrical control means 8. The rod 22 passes under the fixed rail 2 and s extends substantially transversely. The rotation of the lever 20 drives the actuating means 12 when manual control of the movement of the needle rails is selected, as described later.

La tringle 22 est reliée à une de ses parties extrêmes au levier 20 par l'intermédiaire d'une cascade de pignons 24, ce qui permet de surélever le levier 20 par rapport à la tringle 22 et le rendre ainsi plus accessible pour la commande manuelle. L'autre partie extrême de la tringle 22 est reliée à un arbre (non représenté) saillant du boîtier 14 par l'intermédiaire d'une autre cascade de pignon 26. La cascade de pignon 26 est accouplée en rotation à la sortie 17 des moyens de commande électriques 8, par exemple tel que cela est décrit dans le document FR-2 896 752 .The rod 22 is connected to one of its extreme parts to the lever 20 via a gear cascade 24, which allows to raise the lever 20 relative to the rod 22 and thus make it more accessible for manual control. The other end portion of the rod 22 is connected to a shaft (not shown) projecting from the casing 14 via another gear cascade 26. The gear cascade 26 is coupled in rotation to the outlet 17 of the means electrical control device 8, for example as described in the document FR-2,896,752 .

La sortie 17 des moyens de commande électriques 8 est solidaire de la partie extrême 27 d'une première barre de commande 28 s'étendant sensiblement transversalement et passant sous le rail fixe 2 de sorte que l'autre partie extrême 30 de la première barre de commande 28 est disposée en dehors de l'espace s'étendant entre les deux rails fixes 2 et 4. La rotation de la sortie 17 des moyens de commande entraîne le déplacement en translation selon une direction sensiblement transversale de la première barre de commande 28, comme indiqué par la flèche F1 de la Fig. 1.The output 17 of the electrical control means 8 is secured to the end portion 27 of a first control bar 28 extending substantially transversely and passing under the fixed rail 2 so that the other end portion 30 of the first bar control 28 is disposed outside the space extending between the two fixed rails 2 and 4. The rotation of the output 17 of the control means causes the displacement in translation in a substantially transverse direction of the first control bar 28, as indicated by the arrow F 1 of the Fig. 1 .

L'autre partie extrême 30 de la première barre de commande 28 est reliée à un premier système de renvoi d'angle 32 qui est relié d'autre part à une partie extrême 34 d'une deuxième barre de commande 36. La deuxième barre de commande 36 s'étend sensiblement longitudinalement le long du rail fixe 2. Le premier système de renvoi d'angle 32 est représenté sur la Fig. 4 et est connu en soi. Il permet de transformer le déplacement transversal de la première barre de commande 28 en déplacement sensiblement longitudinal de la deuxième barre de commande 36, comme indiqué par la flèche F2 de la Fig. 1.The other end portion 30 of the first control bar 28 is connected to a first bevel gear 32 which is further connected to an end portion 34 of a second control bar 36. The second bar control 36 extends substantially longitudinally along the fixed rail 2. The first angle gear system 32 is shown on the Fig. 4 and is known per se. It makes it possible to transform the transverse displacement of the first control bar 28 in substantially longitudinal displacement of the second control bar 36, as indicated by the arrow F 2 of the Fig. 1 .

Pour ajuster les dimensions du dispositif de commande aux contraintes de l'endroit où il est installé, la connexion entre les barres de commande 28 et 36 et le premier système de renvoi d'angle 32 se fait par exemple par un bout fileté prévu à la partie extrême de chaque barre de commande 28 et 36 qui se visse plus ou moins profondément dans une chape respective du premier système de renvoi d'angle 32, comme représenté sur la Fig. 4. Ainsi, les dimensions des moyens d'actionnement peuvent être adaptées au terrain où ils sont installés.To adjust the dimensions of the control device to the constraints of the place where it is installed, the connection between the control rods 28 and 36 and the first angle-translation system 32 is done for example by a threaded end provided for in FIG. end portion of each control bar 28 and 36 which is screwed more or less deeply into a respective clevis of the first angle gear system 32, as shown in FIG. Fig. 4 . Thus, the dimensions of the actuating means can be adapted to the ground where they are installed.

La deuxième barre de commande 36 s'étend vers l'aval le long du rail fixe 2 jusqu'aux rails d'aiguille 6. La distance séparant les moyens de commande électriques 8 et les rails d'aiguille 6, qui correspond sensiblement à la longueur de la deuxième barre de commande 36, peut être assez importante. A cet effet, lorsque cette longueur est importante, un guide de barre 38 est fixé sur le côté du rail fixe 2 et est traversé par la deuxième barre de commande 36 afin d'assurer le support de celle-ci et d'éviter qu'elle ne flambe ou ne se déforme lors de ses déplacements longitudinaux. Le guide de barre 38 est par exemple un guide de barre à rouleaux, connu en soi.The second control bar 36 extends downstream along the fixed rail 2 to the needle rails 6. The distance between the electrical control means 8 and the needle rails 6, which corresponds substantially to the length of the second control bar 36, can be quite large. For this purpose, when this length is important, a guide bar 38 is fixed on the side of the fixed rail 2 and is traversed by the second control bar 36 to ensure the support thereof and to prevent it from flaming or does not deform during its longitudinal movements. The bar guide 38 is for example a roller guide bar, known per se.

L'autre partie extrême 40 de la deuxième barre de commande 36 est reliée à un deuxième système de renvoi d'angle 42 qui est relié d'autre part à une partie extrême 44 d'une troisième barre de commande 46. La troisième barre de commande 46 s'étend sensiblement transversalement et passe sous le rail fixe 2. Le deuxième système de renvoi d'angle 42 est représenté sur la Fig. 5 et est connu en soi. Il permet de transformer le déplacement longitudinal de la deuxième barre de commande 36 en déplacement sensiblement transversal de la troisième barre de commande 46, comme indiqué par la flèche F3 de la Fig. 1.The other end portion 40 of the second control bar 36 is connected to a second angle transmission system 42 which is further connected to an end portion 44 of a third control bar 46. The third bar of control 46 extends substantially transversely and passes under the fixed rail 2. The second system of return angle 42 is shown on the Fig. 5 and is known per se. It makes it possible to transform the longitudinal displacement of the second control bar 36 into a substantially transverse displacement of the third control bar 46, as indicated by the arrow F 3 of the Fig. 1 .

La connexion entre la troisième barre de commande 46 et le deuxième système de renvoi d'angle 42 se fait par exemple par un bout fileté prévu à la partie extrême 44 de la troisième barre de commande 46 qui se visse plus ou moins profondément dans une chape du deuxième système de renvoi d'angle 42, comme représenté sur la Fig. 5, ce qui permet le réglage des dimensions des moyens d'actionnement en fonction du terrain où ils sont installés.The connection between the third control bar 46 and the second angle transmission system 42 is for example by a threaded end provided at the end portion 44 of the third control bar 46 which screws more or less deeply into a clevis of the second deflection system 42, as shown in FIG. Fig. 5 , which allows the adjustment of the dimensions of the actuating means according to the ground where they are installed.

L'autre partie extrême 48 de la troisième barre de commande 46 est reliée à une tringle transversale 50 s'étendant entre les deux rails d'aiguille 6 et solidaire de ceux-ci. Ainsi, lorsque la troisième barre de commande 46 est déplacée transversalement suite à la commande des moyens de commande électriques 8 ou manuels 10, la troisième barre de commande 46 entraîne le déplacement de la tringle 50 qui entraîne le déplacement selon une direction sensiblement transversale des rails d'aiguilles 6.The other end portion 48 of the third control bar 46 is connected to a transverse rod 50 extending between the two needle rails 6 and integral therewith. Thus, when the third control bar 46 is moved transversely following the control of the electrical control means 8 or manual 10, the third control bar 46 causes the movement of the rod 50 which causes the displacement in a substantially transverse direction of the rails needles 6.

Les connexions entre la sortie 17 des moyens de commande électriques 8 et la première barre de commande 28, entre les première, deuxième et troisième barres de commande 28, 36, 46 et les premier et deuxième systèmes de renvoi d'angle 32, 42, entre la troisième barre de commande 46 et la tringle 50, et entre la tringle 50 et les rails d'aiguille 6 se font par des liaisons pivot afin d'éviter toute déformation de l'aiguillage, lors des déplacements de ces différents éléments les uns par rapport aux autres.The connections between the output 17 of the electrical control means 8 and the first control bar 28, between the first, second and third control rods 28, 36, 46 and the first and second angle transmission systems 32, 42, between the third control bar 46 and the rod 50, and between the rod 50 and the needle rails 6 are made by pivot connections to prevent any deformation of the switch, during the movements of these different elements. compared to others.

L'aiguillage 1 comprend en outre des moyens de commutation 52 entre les moyens de commande électriques 8 et les moyens de commande manuels 10 afin de permettre à un opérateur de basculer de la commande électrique à la commande manuelle de l'aiguillage. Ces moyens de commutation 52 sont disposés à l'extérieur des rails fixes 2 et 4 afin de permettre leur actionnement sans accéder à l'espace s'étendant entre les rails fixes, comme représenté sur la Fig. 1. Les moyens de commutation 52 sont par exemple fixés sur une paroi d'un tunnel lorsque l'aiguillage 1 est installé sur une voie souterraine. Les moyens de commutation 52 sont par exemple reliés par un câble de tirage 53 à un doigt 54 des moyens de commande électriques 8. L'actionnement des moyens de commutation 52 entraîne le déplacement du doigt 54 par l'intermédiaire du câble 53, ce qui entraîne le basculement entre l'actionnement électrique et l'actionnement manuel, de façon connue en soi. L'actionnement des moyens de commutation 52 peut être sécurisé, par exemple en prévoyant un actionnement au moyen d'une ou plusieurs clés, afin d'empêcher un actionnement accidentel ou malveillant de l'aiguillage 1.The switch 1 further comprises switching means 52 between the electrical control means 8 and the manual control means 10 to allow an operator to switch from the electrical control to the manual control of the switch. These switching means 52 are arranged outside the fixed rails 2 and 4 to allow their actuation without accessing the space extending between the fixed rails, as shown in FIG. Fig. 1 . The switching means 52 are for example fixed on a wall of a tunnel when the switch 1 is installed on a subterranean path. The switching means 52 are for example connected by a pull cable 53 to a finger 54 of the electrical control means 8. The actuation of the switching means 52 causes the finger 54 to move by means of the cable 53, which causes switching between the electric actuation and the manual actuation, in a manner known per se. The actuation of the switching means 52 can be secured, for example by providing actuation by means of one or more keys, to prevent accidental or malicious operation of the switch 1.

L'aiguillage décrit ci-dessus est peu encombrant tout en respectant les normes de sécurité. En effet, le boîtier 14 des moyens de commande électriques 8 est disposé entre les rails fixes 2 et 4, c'est-à-dire à un endroit où l'espace n'est pas restreint, tandis que les moyens d'actionnement manuels 10 et les moyens de commutation 52 sont disposés à l'extérieur des rails fixes 2 et 4, c'est-à-dire à un endroit où un opérateur peut y accéder sans accéder à l'espace entre les rails 2 et 4, ce qui est interdit lorsque des véhicules ferroviaires circulent sur les rails 2 et 4.The switch described above is compact while respecting safety standards. Indeed, the housing 14 of the electrical control means 8 is disposed between the fixed rails 2 and 4, that is to say at a place where the space is not restricted, while the manual actuating means 10 and the switching means 52 are arranged outside the fixed rails 2 and 4, that is to say at a place where an operator can access it without accessing the space between the rails 2 and 4, this which is forbidden when rail vehicles run on rails 2 and 4.

Un tel aiguillage 1 ne nécessite donc pas un espace important sur le côté des rails fixes pour son installation et peut facilement être installé sur une voie passant par exemple dans un tunnel. Il n'est alors pas nécessaire de creuser une niche dans la paroi du tunnel pour disposer d'un espace suffisant pour l'aiguillage 1. Cet aiguillage 1 peut facilement être installé sur des rails fixes 2 et 4 déjà posés, car il ne nécessite pas de modifier l'installation de ceux-ci.Such a switch 1 does not require a large space on the side of the fixed rails for installation and can easily be installed on a path passing for example in a tunnel. It is not necessary to dig a niche in the tunnel wall to have sufficient space for the switch 1. This switch 1 can easily be installed on fixed rails 2 and 4 already installed because it does not require not change the installation of these.

Les emplacements des moyens de commande manuels et des moyens de commutation peuvent être sélectionnés pour être le plus pratique possible et l'aiguillage 1 est donc facilement modulable et peut être adapté à de nombreuses configurations de terrain.The locations of the manual control means and the switching means can be selected to be as practical as possible and the switch 1 is therefore easily adjustable and can be adapted to many terrain configurations.
