Description

DISPOSITIF D'ARRIMAGE D'UN APPAREIL DE VOIE FERREE DEVICE FOR STACKING A RAILWAY APPARATUS
DOMAINE TECHNIQUE DE L'INVENTION TECHNICAL FIELD OF THE INVENTION
[0001] L' invention se rapporte à un dispositif d'arrimage d'un appareil de voie ferrée, notamment d'un aiguillage. Elle se rapporte également à un véhicule de transport, notamment un wagon, intégrant un tel dispositif d'arrimage.  The invention relates to a securing device of a railroad apparatus, including a switch. It also relates to a transport vehicle, including a wagon, incorporating such a securing device.
ETAT DE LA TECHNIQUE ANTERIEURE STATE OF THE PRIOR ART
[0002] Dans le document FR3024470 est décrit un wagon de transport d'un appareil de voie ferrée, comportant une plateforme de support de l'appareil de voie ferrée, présentant une surface d'appui pour l'appareil de voie ferrée, la plateforme de support étant mobile entre une position horizontale de chargement et une position inclinée de transport. L'appareil de voie est fixé à la plateforme de support par un mécanisme d'arrimage constitué de brides individuelles, réparties sur l'ensemble de l'appareil de voie ferrée, disposées entre les traverses de l'appareil de voie et la plateforme.  In FR3024470 is described a transport wagon of a railroad apparatus, comprising a support platform of the railroad apparatus, having a bearing surface for the railroad apparatus, the platform carrier being movable between a horizontal loading position and an inclined transport position. The switchgear is fixed to the support platform by a securing mechanism consisting of individual flanges distributed over the entire railway apparatus, arranged between the crosspieces of the switchgear and the platform.
[0003] Un tel mode de fixation, particulièrement simple, présente toutefois l'inconvénient de nécessiter un accès à la plateforme de chargement pour venir manuellement serrer les brides, donc avant que l'appareil de voie soit sécurisé. Des précautions particulières sont donc nécessaires pour la manutention tant dans les phases de chargement que dans celles de déchargement, ceci afin d'assurer la sécurité du personnel. Such a method of attachment, particularly simple, however, has the disadvantage of requiring access to the loading platform to manually come clamp the flanges, so before the switch device is secure. Special precautions are therefore necessary for handling both in the loading and unloading phases, in order to ensure the safety of the personnel.
[0004] Afin de permettre de fixer l'appareil de voie à la plateforme sans avoir besoin d'accéder à la plateforme, la société MAT1SA SA a mis sur le marché depuis 2006 au moins un mécanisme d'arrimage d'appareil de voie, comportant des barres de fixation, portant à une extrémité un crochet destiné à venir se positionner en prise avec une partie d’un pied d'un rail de l'appareil de voie. Chaque barre est montée coulissante dans un manchon articulé à la plateforme de façon à pivoter autour d'un axe longitudinal qui est perpendiculaire à la barre. L'opérateur peut ainsi manœuvrer la barre à la manière d'un levier, en la tenant par son extrémité libre opposée au crochet pour la faire pivoter jusqu'à approcher le crochet du pied du rail, tout en ajustant la longueur utile de la barre en la faisant coulisser dans le manchon. Une fois le crochet engagé avec le pied du rail, il ne reste qu'à bloquer le coulissement de la barre dans le manchon pour verrouiller le crochet et l'appareil de voie en position par rapport à la [0004] In order to make it possible to fix the switchgear to the platform without having to access the platform, the MAT1SA SA company has put on the market since 2006 at least one lashing mechanism for securing a switchgear, with fixing bars, carrying at one end a hook intended to engage with a part of a foot of a rail of the switchgear. Each bar is slidably mounted in a sleeve hinged to the platform so as to pivot about a longitudinal axis which is perpendicular to the bar. The operator can thus maneuver the bar in the manner of a lever, holding it by its free end opposite the hook to rotate it to approach the hook of the foot of the rail, while adjusting the useful length of the bar by sliding it into the sleeve. Once the hook engaged with the foot of the rail, all that remains is to block the sliding of the bar in the sleeve to lock the hook and the switchgear in position relative to the
FEUILLE DE REMPLACEMENT (RÈGLE 26) plateforme. La longueur de la barre permet à l'opérateur d'agir tout en restant à distance du crochet, sur le côté de la plateforme. Le système ainsi décrit est très similaire au système illustré dans le document W02014154624A1. 11 est efficace, mais ne permet pas d'obtenir une force de serrage importante entre le crochet et l'appareil de voie, ceci notamment parce que la force appliquée par le crochet sur le pied du rail lors de la mise en place et de l'immobilisation est dans la direction générale de la barre, légèrement oblique par rapport à l'horizontale, donc avec une forte composante horizontale qui tend à faire glisser l'appareil de voie sur la plateforme. Ce dispositif est par ailleurs difficile à motoriser. SUBSTITUTE SHEET (RULE 26) platform. The length of the bar allows the operator to act while remaining at a distance from the hook on the side of the platform. The system thus described is very similar to the system illustrated in WO2014154624A1. 11 is effective, but does not allow to obtain a significant clamping force between the hook and the switchgear, this in particular because the force applied by the hook on the foot of the rail during installation and maintenance. immobilization is in the general direction of the bar, slightly oblique with respect to the horizontal, so with a strong horizontal component which tends to slide the apparatus of way on the platform. This device is also difficult to motorize.
[0005] Pour y remédier, le document FR1653185 propose un dispositif d’arrimage d’appareil de voie ferrée une plateforme de support dont le mécanisme d’arrimage comporte un chariot guidé par une glissière de guidage, des moyens de blocage du chariot par rapport à la glissière et des organes de verrouillage de la glissière de guidage par rapport à la plateforme. Les organes de verrouillage comprennent notamment une cale en biseau venant en prise avec une paroi inclinée correspondante d'une cavité de verrouillage formée dans la plateforme de support. Un tel dispositif est simple à motoriser et permet d’obtenir une manutention sécurisée de l'appareil de voie ferrée car le mouvement de l'organe de fixation est ainsi décomposé en au moins deux composantes, à savoir un mouvement horizontal et un mouvement vertical grâce à la forme en biseau de la cale. Cependant, la réalisation de la cale en biseau et de la cavité de verrouillage associée peut s’avérer complexe. To remedy this, the document FR1653185 proposes a railroad device securing device a support platform whose lashing mechanism comprises a carriage guided by a guide rail, locking means of the carriage relative to to the slide and locking members of the guide rail relative to the platform. The locking members comprise in particular a bevel wedge engaging a corresponding inclined wall of a locking cavity formed in the support platform. Such a device is simple to motorize and makes it possible to obtain a secure handling of the railway apparatus since the movement of the fastener is thus broken down into at least two components, namely a horizontal movement and a vertical movement thanks to to the wedge shape of the hold. However, the realization of the bevel wedge and the associated locking cavity can be complex.
EXPOSE DE L'INVENTION SUMMARY OF THE INVENTION
[0006] L’ invention a pour but de remédier aux inconvénients de l’état de la technique en proposant un dispositif d'arrimage d'un appareil de voie ferrée qui permette une manutention simple et sécurisée de l'appareil de voie ferrée, soit simple à motoriser, mais également à réaliser. Un autre but de l’invention est de régler avec précision la hauteur du mécanisme de fixation pour s’adapter aux différentes hauteurs de traverses, comme par exemple à celles en bois (de faible hauteur) ou en béton (de hauteur plus importante).  The invention aims to overcome the disadvantages of the state of the art by providing a securing device of a railroad apparatus that allows a simple and secure handling of the railroad device, either simple to motorize, but also to achieve. Another object of the invention is to adjust precisely the height of the fastening mechanism to adapt to different heights of sleepers, such as those of wood (low height) or concrete (higher height).
[0007] A cet effet, l’invention concerne un dispositif d'arrimage d'un appareil de voie ferrée comportant une plateforme de support de l’appareil de voie ferrée et au moins un mécanisme d'arrimage de l'appareil de voie ferrée sur la plateforme de support apte à passer d’une position de verrouillage à une position de déverrouillage et vice versa, le mécanisme d'arrimage comportant : au moins une glissière de guidage s’étendant selon une direction longitudinale; au moins un organe de fixation de l’appareil de voie ferrée à la plateforme de support apte à se déplacer le long de la glissière de guidage; For this purpose, the invention relates to a securing device of a railroad apparatus comprising a support platform of the railway apparatus and to the minus a securing mechanism of the railway apparatus on the support platform adapted to pass from a locking position to an unlocking position and vice versa, the securing mechanism comprising: at least one guide rail; extending in a longitudinal direction; at least one fastening member of the track apparatus to the support platform adapted to move along the guide rail;
caractérisé en ce que le mécanisme d’arrimage comprend en outre :  characterized in that the docking mechanism further comprises:
- une poutre supérieure supportant la glissière de guidage ; et  an upper beam supporting the guide rail; and
- une poutre inférieure reliée à la plateforme de support,  a lower beam connected to the support platform,
la poutre supérieure et la poutre inférieure étant reliées par l’intermédiaire d’au moins un organe de liaison configuré de sorte que la poutre supérieure est déplaçable par rapport à la poutre inférieure selon une direction perpendiculaire à la direction longitudinale de la glissière de guidage,  the upper beam and the lower beam being connected by means of at least one connecting member configured so that the upper beam is displaceable relative to the lower beam in a direction perpendicular to the longitudinal direction of the guide rail,
et en ce que le mécanisme d’arrimage comprend des moyens de verrouillage dudit au moins un organe de liaison, configurés pour empêcher le déplacement de la poutre supérieure par rapport à la poutre inférieure.  and in that the securing mechanism comprises locking means of said at least one connecting member, configured to prevent displacement of the upper beam relative to the lower beam.
[0008] Grâce à l’invention, le mouvement de l'organe de fixation est toujours décomposé en au moins deux composantes, à savoir un mouvement de l’organe de liaison selon la direction longitudinale de la glissière, et un mouvement de la poutre supérieure selon une direction perpendiculaire à la direction longitudinale de la glissière. Toutefois, à la différence de l’art antérieur, le mécanisme permettant cette décomposition du mouvement en deux composantes est bien plus simple de fabrication et d’utilisation. En effet, deux mécanismes distincts permettent ces mouvements selon deux directions différentes, et non un seul comme dans l’art antérieur. Thanks to the invention, the movement of the fastener is always decomposed into at least two components, namely a movement of the connecting member in the longitudinal direction of the slide, and a movement of the beam upper in a direction perpendicular to the longitudinal direction of the slide. However, unlike the prior art, the mechanism for this decomposition of the movement into two components is much simpler to manufacture and use. Indeed, two distinct mechanisms allow these movements in two different directions, and not one as in the prior art.
[0009] Par ailleurs, dans la mesure où c’est la poutre supérieure supportant la glissière de guidage le long de laquelle se déplace l’organe de fixation qui se déplace, on peut facilement régler avec précision la hauteur du mécanisme de fixation pour s’adapter aux différentes hauteurs de traverses. [0010] Selon un mode de réalisation particulier de l’invention, l’organe de liaison est un ensemble formant parallélogramme articulé comprenant au moins une bielle de transmission reliée à la poutre supérieure et un levier de transfert relié à la poutre inférieure commandé par un ensemble vis et écrou ou un vérin, de sorte que le déplacement de la poutre supérieure soit cinématiquement lié au déplacement de la vis dans l’écrou ou respectivement de la tige de vérin dans le corps du vérin. Ce choix d’organe de liaison permet de limiter l’encombrement et d’obtenir une bonne répartition des efforts entre la poutre inférieure et la poutre supérieure. Moreover, since it is the upper beam supporting the guide rail along which moves the fixing member which moves, it is easy to adjust precisely the height of the fastening mechanism for s to adapt to different heights of sleepers. According to a particular embodiment of the invention, the connecting member is an articulated parallelogram assembly comprising at least one transmission link connected to the upper beam and a transfer lever connected to the lower beam controlled by a screw and nut assembly or cylinder, so that the displacement of the upper beam is kinematically related to the displacement of the screw in the nut or respectively the cylinder rod in the cylinder body. This choice of connecting member makes it possible to limit the space requirement and to obtain a good distribution of the forces between the lower beam and the upper beam.
[0011] Selon un autre mode de réalisation particulier de l’invention, l’organe de liaison est un ensemble de vis et écrou, par exemple de forme trapézoïdale, dont la vis est portée par la poutre inférieure et l’écrou est porté par la poutre supérieure, de sorte que le déplacement de la poutre supérieure soit cinématiquement lié au déplacement de l’écrou le long de la vis et que le verrouillage soit assuré par le couple de serrage de l’ensemble de vis et écrou.. La vis ou le vérin sont en effet des organes de liaison peu coûteux et particulièrement simples à réaliser. Le déplacement de la vis dans le pas de vis ou du vérin dans le corps du vérin permet de plus de contrôler précisément le déplacement de la poutre supérieure. According to another particular embodiment of the invention, the connecting member is a set of screws and nuts, for example of trapezoidal shape, the screw is carried by the lower beam and the nut is carried by the upper beam, so that the displacement of the upper beam is kinematically linked to the displacement of the nut along the screw and the locking is ensured by the tightening torque of the screw and nut assembly. or the cylinder are indeed inexpensive connecting members and particularly simple to achieve. The displacement of the screw in the thread or cylinder in the cylinder body also allows precise control of the displacement of the upper beam.
[0012] Afin de pouvoir absorber avec le dispositif d’arrimage la différence de hauteur des différents modèles d’appareil de de voie en béton ou en en bois, la course de déplacement de la poutre supérieure est d’au moins 130mm. In order to be able to absorb with the securing device the difference in height of different models of concrete or wooden track apparatus, the displacement of the upper beam travel is at least 130mm.
[0013] De préférence, le mécanisme d’arrimage comprend deux poutres supérieure reliées à une poutre inférieure, deux glissières de guidage et deux organes de liaison reliant respectivement chaque poutre supérieure à la poutre inférieure, les organes de liaison étant aptes à être pilotés de manière indépendante. Ainsi, on peut accrocher les deux extrémités de manière indépendante, ce qui évite un porte-à-faux, la force de serrage par crochet étant constante quelle que soit la position du crochet dans la glissière de guidage. L’utilisateur se trouve ainsi déchargé d’une contrainte de vigilance supplémentaire et peut se permettre d’être moins attentif. La sécurité de manipulation s’en retrouve donc accrue. [0014] Pour faciliter l’utilisation du dispositif, l’organe de fixation est mû le long de la glissière de guidage par un mécanisme d'entraînement, de préférence autobloquant, afin d’apporter une sécurité supplémentaire au dispositif. Preferably, the securing mechanism comprises two upper beams connected to a lower beam, two guide rails and two connecting members respectively connecting each upper beam to the lower beam, the connecting members being adapted to be driven by independently. Thus, one can hang the two ends independently, which avoids a door overhang, the clamping force per hook is constant regardless of the position of the hook in the guide rail. The user is thus relieved of additional vigilance and can afford to be less attentive. The security of handling is thus increased. To facilitate the use of the device, the fastener is moved along the guide rail by a drive mechanism, preferably self-locking, to provide additional security to the device.
[0015] Selon un mode de réalisation préféré de l’invention, le mécanisme d'entraînement comprend une chaîne mobile apte à se déplacer le long de la glissière de guidage qui est entraînée par au moins deux roue dentées de manière à ce que la chaîne mobile forme une boucle. L’entraînement à l’aide d’une chaîne mobile permet d’obtenir un mécanisme naturellement autobloquant, à la fois simple de fabrication et de mise en œuvre. According to a preferred embodiment of the invention, the drive mechanism comprises a movable chain capable of moving along the guide rail which is driven by at least two toothed wheels so that the chain mobile forms a loop. The drive with a mobile chain provides a naturally self-locking mechanism, both simple manufacturing and implementation.
[0016] Selon un mode de réalisation particulier, ayant l’avantage d’être simple de mise en œuvre, ladite au moins une des roues dentées, dite roue d’entraînement, est munie d’un axe d’entraînement, ledit axe d’entraînement étant relié à un moteur de manière à entraîner la roue d’entraînement en rotation atour dudit axe d’entraînement. According to a particular embodiment, having the advantage of being simple to implement, said at least one of the toothed wheels, said drive wheel, is provided with a drive shaft, said drive shaft. the drive being connected to a motor so as to drive the drive wheel in rotation around said drive shaft.
[0017] Selon un mode de réalisation préféré de l’invention, afin d’apporter une sécurité supplémentaire au dispositif, la roue d’entraînement est munie d’un système de freinage permettant d’empêcher la rotation de la roue d’entraînement autour de son axe d’entraînement. According to a preferred embodiment of the invention, in order to provide additional security to the device, the drive wheel is provided with a braking system to prevent rotation of the drive wheel around of its drive axis.
[0018] Selon un mode de réalisation préféré de l’invention, le système de freinage est de type à commande de repos, et comprend par exemple une paire de disques de freinage. Ainsi, par défaut, c’est-à-dire sans alimentation, le système de freinage empêche la rotation de la roue d’entraînement autour de son axe d’entraînement. 11 est donc nécessaire d’alimenter le système de freinage pour desserrer le frein. According to a preferred embodiment of the invention, the braking system is of the idle control type, and comprises for example a pair of braking disks. Thus, by default, that is to say without power, the braking system prevents the rotation of the drive wheel around its drive axis. It is therefore necessary to supply the braking system to release the brake.
[0019] Selon un mode de réalisation préféré de l’invention, simple de mise en œuvre et d’utilisation pour les opérateurs, la plateforme de support est mobile entre la position de chargement et une position inclinée de transport, de préférence par rotation autour d'au moins un axe de pivotement horizontal. According to a preferred embodiment of the invention, simple implementation and use for operators, the support platform is movable between the loading position and an inclined transport position, preferably by rotation around at least one horizontal pivot axis.
[0020] Selon un mode de réalisation préféré de l’invention, de manière à supprimer tout effort musculaire pour l’opérateur, le mécanisme d’arrimage est piloté par une télécommande ou une télécommande de secours en cas de défaillance de la première. [0021] De préférence, le mécanisme de fixation est configuré de sorte à pouvoir pivoter autour d’un axe normal au plan de la plateforme de support, le pivotement du mécanisme de fixation étant par exemple assuré par des moyens d’entraînement comprenant des vérins. Ceci permet d’ajuster la position du mécanisme de fixation pour compenser des éventuels défauts d’alignement. According to a preferred embodiment of the invention, so as to eliminate any muscular effort for the operator, the securing mechanism is controlled by a remote control or a backup remote control in case of failure of the first. Preferably, the fastening mechanism is configured so as to be pivotable about an axis normal to the plane of the support platform, the pivoting of the fastening mechanism being for example provided by drive means comprising cylinders . This makes it possible to adjust the position of the fixing mechanism to compensate for any misalignment.
[0022] L’ invention concerne également un véhicule de transport d'un appareil de voie ferrée, en particulier wagon de transport d'un appareil de voie ferrée, caractérisé en ce qu'il comporte un système d'arrimage selon l’invention monté sur un châssis de transport supporté par des trains roulants. The invention also relates to a vehicle for transporting a railroad track apparatus, in particular a carriage for transporting a railway track apparatus, characterized in that it comprises a securement system according to the invention mounted on a transport chassis supported by running gear.

DESCRIPTION DÉTAILLÉE DE MODES DE REALISATION DETAILED DESCRIPTION OF EMBODIMENTS
[0024] Sur la figure 1 est illustré un wagon de transport 10 en cours de chargement d'un appareil de voie 12 (visible à la figure 3) de grande dimension, et notamment de largeur supérieure au gabarit de circulation 14 prescrit pour le transport ferroviaire. L’appareil de voie 12 est par exemple, comme on peut le voir à la figure 3, un aiguillage comprenant des rails 16 et des traverses d’aiguillage 18.  In Figure 1 is illustrated a transport wagon 10 being loaded a track apparatus 12 (shown in Figure 3) of large size, and in particular of greater width than the circulation gauge 14 prescribed for transport rail. The track apparatus 12 is for example, as can be seen in FIG. 3, a switch comprising rails 16 and switch rails 18.
[0025] Comme on peut le voir à la figure 2 en particulier, le wagon de transport 10 comporte un châssis 20 dont la largeur est inférieure ou égale à la largeur du gabarit circulation 14. L’arrimage de l’appareil de voie 12 au wagon de transport est assuré par un dispositif d’arrimage 22 comprenant une plateforme de support 24 de l'appareil de voie 12 articulée au châssis 20 par une articulation 25 permettant un pivotement autour d'un axe horizontal parallèle à l'axe longitudinal ZZ du châssis 20, qui est lui- même normal au plan de la figure 2. As can be seen in Figure 2 in particular, the transport car 10 comprises a frame 20 whose width is less than or equal to the width of the circulation template 14. The lashing of the track apparatus 12 to transport wagon is provided by a securing device 22 comprising a support platform 24 of the track apparatus 12 articulated to the frame 20 by a hinge 25 allowing pivoting about a horizontal axis parallel to the longitudinal axis ZZ of the frame 20, which is itself normal to the plane of Figure 2.
[0026] Sur les figures 1 et 2, la plateforme de support 24 est inclinée par rapport à un plan de référence parallèle au plan de la voie sur laquelle circule le wagon de transport 10. Un ou plusieurs vérins hydrauliques (non représentés), ou tout autre type d'actionneur motorisé, permettent de faire pivoter la plateforme inclinable de support 24 entre une position de chargement, illustrée à la figure 3 dans laquelle la plateforme de support 24 se trouve dans un plan de chargement P (représenté en pointillés sur les figures 3 et 5 à 11, et qui correspond au plan de la figure 4), et une position inclinée de transport illustrée sur les figure 1 et 2. Figures 1 and 2, the support platform 24 is inclined relative to a reference plane parallel to the plane of the track on which the car of transport 10. One or more hydraulic cylinders (not shown), or any other type of motorized actuator, make it possible to pivot the tilting support platform 24 between a loading position, illustrated in FIG. 3 in which the support platform 24 is in a loading plane P (shown in dashed lines in FIGS. 3 and 5 to 11, and which corresponds to the plane of FIG. 4), and an inclined transport position illustrated in FIGS. 1 and 2.
[0027] La plateforme de support 24 est de préférence en deux parties ou davantage afin de rendre la structure du dispositif d’arrimage 22 moins rigide. En l’occurrence, la plateforme de support 24 est de préférence une structure mécanosoudée. Elle comprend des longerons 24a et des traverses 24b sur laquelle vient monter au moins un mécanisme d’arrimage 30. Cet ensemble complet peut soit être en position relevée (figure 2) soit pivoter autour de l’articulation 25 jusqu’à une position horizontale pour le chargement et déchargement. Le dispositif d’arrimage 22 comprend en outre un mécanisme d’arrimage 30 comprenant une poutre inférieure 26 et une poutre supérieure 27 reliée à la plateforme de support 24. Le mécanisme d'arrimage 30 est prévu pour arrimer l'appareil de voie 12 à la plateforme de support 24. The support platform 24 is preferably in two or more parts to make the structure of the securing device 22 less rigid. In this case, the support platform 24 is preferably a mechanically welded structure. It comprises rails 24a and cross members 24b on which is mounted at least one lashing mechanism 30. This complete assembly can either be in the raised position (FIG. 2) or pivot about the hinge 25 to a horizontal position for loading and unloading. The lashing device 22 further comprises a lashing mechanism 30 comprising a lower beam 26 and an upper beam 27 connected to the support platform 24. The lashing mechanism 30 is provided for securing the lane apparatus 12 to the support platform 24.
[0028] Dans le mode de réalisation illustré sur les figures, en particulier sur les figures 1 à 9, le dispositif d’arrimage 22 comprend quatre mécanismes d’arrimage 30. On notera que le dispositif d’arrimage 22 peut comporter moins ou davantage de mécanisme d’arrimage selon les besoins, en particulier selon le nombre et la dimension des appareils de voie à transporter. In the embodiment illustrated in the figures, in particular in Figures 1 to 9, the securing device 22 comprises four securing mechanisms 30. It will be noted that the securing device 22 may comprise less or more of a lashing mechanism as required, in particular according to the number and size of the lanes to be transported.
[0029] Le mécanisme d’arrimage 30 sont ici mobiles sur la plateforme 24 le long de l’axe longitudinal ZZ du châssis 20, de façon indépendante les uns par rapport aux autres. Ceci permet de s’adapter aux diverses contraintes du chargement ou du transport, de même qu’aux dimensions ou forme des appareils de voie à transporter. The docking mechanism 30 are here movable on the platform 24 along the longitudinal axis ZZ of the frame 20, independently from each other. This makes it possible to adapt to the various constraints of the loading or the transport, as well as to the dimensions or form of the apparatus of way to be transported.
[0030] La poutre supérieure 27 et la poutre inférieure 26 sont reliées par l’intermédiaire d’au moins un organe de liaison 31. Cet organe de liaison 31 configuré de sorte que la poutre supérieure 27 soit déplaçable par rapport à la poutre inférieure 26 selon une direction perpendiculaire N à la direction longitudinale L d’une glissière de guidage 32 portée par la poutre supérieure 27 qui sera décrite plus loin. En particulier, la poutre supérieure 27 et la poutre inférieure 26 sont reliées par l’intermédiaire de deux organes de liaison 31 disposés de part et d’autre d’un plan de symétrie S de la plateforme de support 24, qui est normal au plan de chargement P. The upper beam 27 and the lower beam 26 are connected via at least one connecting member 31. This connecting member 31 configured so that the upper beam 27 is movable relative to the lower beam 26 in a direction perpendicular N to the longitudinal direction L of a guide rail 32 carried by the upper beam 27 which will be described later. In in particular, the upper beam 27 and the lower beam 26 are connected by means of two connecting members 31 arranged on either side of a plane of symmetry S of the support platform 24, which is normal to the plane of loading P.
[0031] Comme il sera détaillé plus loin, chaque mécanisme d’arrimage 30 est apte à passer d’une position de verrouillage, dans laquelle l’appareil de voie 12 est arrimé de façon sécurisée à la plateforme de support 24, et une position de déverrouillage dans laquelle l’appareil de voie 12 peut être désolidarisé de la plateforme de supportAs will be detailed below, each lashing mechanism 30 is adapted to move from a locking position, in which the track apparatus 12 is securely stowed to the support platform 24, and a position unlocking device in which the track apparatus 12 can be detached from the support platform
24. 24.
[0032] A cet effet, chaque mécanisme d'arrimage 30 comprend une glissière de guidage 32, supportée par la poutre supérieure 27, s’étendant selon une direction longitudinale L, supportée par la plateforme de support 24. En particulier, la direction longitudinale L de la glissière de guidage 32 est, lorsque la plateforme de support 24 est en position de chargement, perpendiculaire à l’axe longitudinal du châssis 20 ou à l’axe de la voie ferrée, tout en étant contenue dans le plan libre formée par la plateforme de support 24. For this purpose, each securing mechanism 30 comprises a guide rail 32, supported by the upper beam 27, extending in a longitudinal direction L, supported by the support platform 24. In particular, the longitudinal direction L of the guide rail 32 is, when the support platform 24 is in the loading position, perpendicular to the longitudinal axis of the frame 20 or to the axis of the railway, while being contained in the free plane formed by the support platform 24.
[0033] Chaque mécanisme d’arrimage 30 comprend en outre des organes de fixation 34 de l’appareil de voie 12 à la plateforme de support 24 aptes à se déplacer le long de ces glissières de guidages 32. Dans le mode de réalisation illustré sur les figures, les organes de fixation 34 sont des crochets. Each securement mechanism 30 further comprises fasteners 34 of the track apparatus 12 to the support platform 24 adapted to move along these guide rails 32. In the embodiment illustrated in FIG. the figures, the fasteners 34 are hooks.
[0034] Comme on peut le voir à la figure 3, chaque organe de fixation 34 ou crochet comprend une zone d’accrochage 35 destinée à venir en prise avec le pied 18a d'un des rails 18 de l’aiguillage 16. As can be seen in Figure 3, each fastener 34 or hook comprises a hooking zone 35 intended to engage with the foot 18a of one of the rails 18 of the switch 16.
[0035] Un mécanisme d'entraînement 36 est associé à chaque organe de fixation 34 et permet son déplacement le long de à la glissière de guidage 32 associée. Ce mécanisme d’entraînement 36 est de préférence autobloquant, pour éviter tout déplacement intempestif de l’organe de fixation 34 et en particulier lors du déplacement du wagon de transport 10. A drive mechanism 36 is associated with each fastener 34 and allows its movement along the associated guide rail 32. This drive mechanism 36 is preferably self-locking, to prevent inadvertent movement of the fastener 34 and in particular during the displacement of the transport car 10.
[0036] Dans le mode de réalisation représenté sur les figures, et comme on peut le voir en particulier aux figures 3 et 4, chaque mécanisme d'entraînement 36 comprend ici une chaîne mobile 38 apte à se déplacer le long de la glissière de guidage 32, à laquelle est relié l’organe de fixation 34. Plus particulièrement, chaque chaîne 38 est guidée par la glissière de guidage 32 associée de manière à ce que l’organe de fixation 34 puisse être déplacé le long de la glissière de guidage 32. La glissière de guidage 36 définit ainsi une trajectoire linéaire, et de préférence rectilinéaire, pour l’organe de fixation 34. Cette trajectoire est contenue dans le plan de chargement P. En pratique, la glissière 36 est ici constituée par un rail de section de forme générale en U, formant ainsi une gorge le long de laquelle la chaîne 38 peut être déplacée. In the embodiment shown in the figures, and as can be seen in particular in FIGS. 3 and 4, each drive mechanism 36 comprises here a movable chain 38 adapted to move along the guide rail 32, to which the fixing member 34 is connected. More particularly, each chain 38 is guided by the associated guiding slide 32 so that the fixing member 34 can be moved along the guide slide 32. The guide slide 36 thus defines a linear trajectory, and preferably rectilinear, for the fastener 34. This trajectory is contained in the loading plane P. In practice, the slideway 36 is constituted by a generally U-shaped section rail, thus forming a groove along which the chain 38 can be moved.
[0037] Chaque chaîne 38 est entraînée par au moins deux roues dentées 40, notamment de manière à ce que la chaîne 38 forme une boucle. Dans le mode de réalisation illustré sur les figures, les roues dentées 40 sont au nombre de six. Deux roues dentées 40 sont disposées à une première extrémité 38a de la boucle qui est la plus proche du centre de la plateforme 24, et quatre à l’extrémité opposée 38e de la boucle se trouvant la plus proche de l’extrémité libre 32a de la glissière de guidage 32. Each chain 38 is driven by at least two toothed wheels 40, in particular so that the chain 38 forms a loop. In the embodiment illustrated in the figures, the toothed wheels 40 are six in number. Two toothed wheels 40 are disposed at a first end 38a of the loop which is closest to the center of the platform 24, and four at the opposite end 38e of the loop being closest to the free end 32a of the guide rail 32.
[0038] Une de ces roues dentées 40, dite roue d’entraînement 42, est munie d’un axe d’entraînement 44 relié à un moteur 46, par exemple un moteur hydraulique, de manière à entraîner la roue d’entraînement 42 en rotation autour de cet axe d’entraînement 44. Le diamètre de la roue d’entraînement 42 est supérieur à celui des autres roues dentées 40 pour faciliter l’entraînement par le moteur 46. One of these gears 40, said drive wheel 42, is provided with a drive shaft 44 connected to a motor 46, for example a hydraulic motor, so as to drive the drive wheel 42 into rotation around this drive axis 44. The diameter of the drive wheel 42 is greater than that of the other gears 40 to facilitate the drive by the motor 46.
[0039] La roue d’entraînement 42 est ici disposées à l’extrémité 38e de la boucle et est également disposée plus bas que les autres roues dentées 40, c’est-à-dire plus proche de la voie sur lequel circule le wagon de transport 10 en position de chargement. On notera que la disposition et le nombre des roues dentées 40 peut bien entendu varier. On pourra par exemple envisager qu’il n’y ait qu’une roue dentée 40 à chaque extrémité de la boucle formée par la chaîne 38. 11 est également possible de disposer la roue d’entraînement 42 à l’extrémité 38a de la boucle plutôt qu’à l’extrémité 38e. The drive wheel 42 is here disposed at the end 38e of the loop and is also arranged lower than the other gear wheels 40, that is to say closer to the path on which the wagon runs. transport 10 in the loading position. Note that the arrangement and the number of the gears 40 can of course vary. For example, it may be envisaged that there is only one toothed wheel 40 at each end of the loop formed by the chain 38. It is also possible to arrange the drive wheel 42 at the end 38a of the loop rather than at the 38th end.
[0040] La roue d’entraînement 42 est munie d’un système de freinage 48 permettant d’empêcher la rotation de la roue d’entraînement 42 autour de son axe d’entraînement 44. De préférence, le système de freinage 48 est de type à commande de repos et comprend par exemple une paire de disques de freinage 50. Les disques de freinage sont disposés de part et d’autre de la roue d’entraînement 42, comme on peut le voir sur la figure 4, où pour des raisons de clarté, la chaîne 36 a été omise. The drive wheel 42 is provided with a braking system 48 for preventing the rotation of the drive wheel 42 about its drive axis 44. Preferably, the braking system 48 is of command type resting and comprises for example a pair of braking disks 50. The braking disks are arranged on either side of the drive wheel 42, as can be seen in Figure 4, where for reasons of clarity , the chain 36 has been omitted.
[0041] Le système de freinage 48 est configuré de sorte que sans alimentation, il empêche la rotation de la roue d’entraînement 42 autour de son axe. Autrement dit, il est nécessaire d’alimenter le système de freinage 48 pour desserrer les disques de freinage 50. Ce type de système de freinage étant connu en soi de l’homme du métier, il ne sera pas décrit plus en détail ici. The braking system 48 is configured so that without power, it prevents the rotation of the drive wheel 42 about its axis. In other words, it is necessary to supply the braking system 48 to loosen the braking discs 50. This type of braking system is known per se to those skilled in the art, it will not be described in more detail here.
[0042] Le mécanisme d’arrimage 30 étant autobloquant, la position de l’organe de fixation 34 est bloquée dans la direction longitudinale de la glissière de guidage 32. On empêche donc son déplacement selon une première direction. Plus précisément, la chaîne 38 ne peut se mouvoir le long de la glissière de guidage 32 sans, d’une part, le désenclenchent du système de freinage 50, et d’autre part, l’entraînement de la roue d’entraînement 42 par le biais du moteur 46. Une double sécurité de verrouillage est donc assurée pour empêcher le mouvement de l’organe de fixation 34 selon la direction longitudinale de la glissière de guidage 32. The locking mechanism 30 being self-locking, the position of the fastener 34 is locked in the longitudinal direction of the guide rail 32. It prevents its movement in a first direction. More specifically, the chain 38 can not move along the guide rail 32 without, on the one hand, disengage it from the braking system 50, and on the other hand, the driving of the drive wheel 42 by 46. A double locking security is thus provided to prevent the movement of the fastener 34 in the longitudinal direction of the guide rail 32.
[0043] Le mécanisme d’arrimage 30 comprend en outre des moyens de verrouillage 52 de l’organe de liaison 31, configurés pour empêcher le déplacement de la poutre supérieure 27 par rapport à la poutre inférieure 26. The securing mechanism 30 further comprises locking means 52 of the connecting member 31, configured to prevent the displacement of the upper beam 27 relative to the lower beam 26.
[0044] De préférence, ainsi qu’illustré aux figures 3 à 9, l’organe de liaison 31 est un ensemble de vis et écrou 52, par exemple de section trapézoïdale, portée par la poutre supérieure 27, de sorte que le déplacement de la poutre supérieure 27 soit cinématiquement lié au déplacement de l’écrou 56 le long de la vis 54 et que le verrouillage soit assuré par le couple de serrage de l’ensemble de vis et d’écrou 52. Dans ce mode de réalisation particulier, Les moyens de verrouillage 52 sont donc constitués par le serrage de la vis 54 dans l’écrou 56 porté par la poutre inférieure 26. On pourra bien entendu envisager que la forme de la section de la vis 54 diffère. Preferably, as illustrated in FIGS. 3 to 9, the connecting member 31 is a set of screws and nuts 52, for example of trapezoidal section, carried by the upper beam 27, so that the displacement of the upper beam 27 is kinematically linked to the displacement of the nut 56 along the screw 54 and the locking is ensured by the tightening torque of the screw and nut assembly 52. In this particular embodiment, The locking means 52 are constituted by the tightening of the screw 54 in the nut 56 carried by the lower beam 26. It may of course be envisaged that the shape of the section of the screw 54 differs.
[0045] Le serrage de l’ensemble de vis et d’écrou 52 permet d’empêcher le déplacement de la poutre supérieure 27 par rapport à la poutre inférieure 26 selon une direction perpendiculaire à la glissière de guidage 32, qui est également normale au plan de chargement défini par la surface libre de la plateforme de support 24 (ce plan étant représenté schématiquement par la ligne en pointillés P sur la figure 3). La zone d’accrochage 35 de l’organe de fixation 34 étant en contact plan avec le pied du rail 16a selon un plan normal à cette direction, on verrouille ainsi la position de l’organe de fixation 34 selon une deuxième direction perpendiculaire à la direction longitudinale à la glissière de guidage 32. The tightening of the screw and nut assembly 52 makes it possible to prevent the displacement of the upper beam 27 with respect to the lower beam 26 according to a direction perpendicular to the guide rail 32, which is also normal to the loading plane defined by the free surface of the support platform 24 (this plane being shown schematically by the dotted line P in Figure 3). The attachment zone 35 of the fastener 34 being in plane contact with the foot of the rail 16a in a plane normal to this direction, the position of the fixing member 34 is thus locked in a second direction perpendicular to the longitudinal direction to guide rail 32.
[0046] Le déplacement et le serrage de l’ensemble de vis et d’écrou 52, peut être effectué au moyen de moyens d’entrainement connus en soi de l’homme du métier, notamment à l’aide d’un moteur. On ne les décrira donc pas en détail ici. The movement and tightening of the screw and nut assembly 52 may be effected by means of drive means known per se to those skilled in the art, in particular with the aid of a motor. We will not describe them in detail here.
[0047] Un autre avantage du choix d’un ensemble de vis et d’écrou 52 comme organe de liaison 31 est de pouvoir choisir la course de l’écrou 56 le long de la vis54, autrement dit de régler sa hauteur. Ainsi, comme on peut le voir à la figures 5 illustrant les différentes hauteurs de traverses 18, et à la figure 6 illustrant deux positions différentes de la vis 52 dans le pas de vis 54, les zones d’accrochage 35 peuvent se situer, dans la position de fixation, à des hauteurs différentes au-dessus de la poutre inférieure 26. Ceci permet au mécanisme d'être utilisé indifféremment avec des appareils de voies à traverses 18 en bois (de faible hauteur) et à traverses 18 en béton (de hauteur plus importante). Par exemple, compte tenu des hauteurs habituelles des traverses 18 en béton et en bois, on choisit la course de déplacement de la poutre supérieure 27, autrement dit de l’écrou 56 le long de la vis 54 dans ce mode de réalisation particulier, de sorte qu’elle soit d’au moins 130mm. Another advantage of the choice of a set of screws and nut 52 as connecting member 31 is to choose the race of the nut 56 along the screw54, in other words to adjust its height. Thus, as can be seen in FIG. 5 illustrating the different heights of sleepers 18, and in FIG. 6 illustrating two different positions of the screw 52 in the thread 54, the attachment zones 35 can be located, in the fixing position, at different heights above the lower beam 26. This allows the mechanism to be used interchangeably with apparatus of wooden sleepers (of low height) and concrete sleepers 18 (of higher height). For example, given the usual heights of the concrete and wooden sleepers 18, the travel path of the upper beam 27, in other words of the nut 56 along the screw 54 in this particular embodiment, is chosen. so that it is at least 130mm.
[0048] Dans une variante non représentée sur les figures, la vis est remplacée par un vérin et le pas de vis par un corps de vérin. In a variant not shown in the figures, the screw is replaced by a jack and the screw thread by a cylinder body.
[0049] Grâce à la fonction autobloquante du mécanisme d’arrimage 30 d’une part, et à la présence des moyens de verrouillage 52 des organes de liaison 31 d’autre part, le déplacement de l’organe de fixation 34 est respectivement empêché selon la direction longitudinale L de la glissière de guidage 32 et la direction normale N à cette direction longitudinale. La sécurité de l’arrimage de l’appareil de voie 12 à la plateforme de support 24 du dispositif d’arrimage 22 est donc assurée de façon simple et fiable, comme on va maintenir en décrire l’exécution suivant un séquencement illustré aux figures 7 à 9. With the self-locking function of the securing mechanism 30 on the one hand, and the presence of the locking means 52 of the connecting members 31 on the other hand, the displacement of the fastener 34 is respectively prevented in the longitudinal direction L of the guide rail 32 and the normal direction N in this longitudinal direction. The securing safety of the track apparatus 12 to the support platform 24 of the securing device 22 is thus ensured in a simple manner. and reliable, as will be continued to describe the execution according to a sequence shown in Figures 7 to 9.
[0050] Comme on peut le voir sur la figure 12, les mécanismes d’arrimage 30 sont configurés de sorte à pouvoir pivoter autour d’un axe normal au plan de la plateforme de support 24, le pivotement du mécanisme de fixation 30 étant par exemple assuré par des moyens d’entraînement comprenant des vérins 76 de pivotement. La course des vérins 76 s’effectue dans le plan de la plateforme 24, de façon transversale à l’axe longitudinal ZZ du wagon 10, par exemple de façon perpendiculaire à cet axe longitudinal ZZ. As can be seen in Figure 12, the securing mechanisms 30 are configured so as to be pivotable about an axis normal to the plane of the support platform 24, the pivoting of the fastening mechanism 30 being by example provided by drive means comprising jacks 76 pivoting. The stroke of the cylinders 76 is carried out in the plane of the platform 24, transversely to the longitudinal axis ZZ of the wagon 10, for example perpendicular to this longitudinal axis ZZ.
[0051] Sur la figure 7, l'appareil de voie 12, dont on peut voir un rail 18, a été posé sur la plateforme de support 24. Les organes de fixation 34 sont escamotés de façon à ce qu’ils se trouvent en-dessous du plan de chargement, représenté schématiquement par la ligne en pointillés P sur la figure 7, et ce afin d’éviter toute interférence avec l'appareil de voie 12 pendant la manutention. In Figure 7, the track apparatus 12, which can be seen a rail 18, has been placed on the support platform 24. The fasteners 34 are retracted so that they are in position. below the loading plan, shown schematically by the dashed line P in Figure 7, and this to avoid interference with the switchgear 12 during handling.
[0052] Pour réaliser l’arrimage d’un appareil de voie 16 à la plateforme 24, un opérateur règle le positionnement de la vis 54 dans le pas de vis 56 en commandant le moteur associé en fonction de la hauteur de la traverse 18 de façon à ce que le mécanisme d’arrimage 30 arrive au contact du pied du rail 16a. To carry out the lashing of a track apparatus 16 to the platform 24, an operator adjusts the positioning of the screw 54 in the thread 56 by controlling the associated engine as a function of the height of the cross member 18. so that the securing mechanism 30 comes into contact with the foot of the rail 16a.
[0053] Puis, l’opérateur débloque le système de freinage 48 et commande le moteur 46 pour permettre l’entraînement de la roue d’entraînement 42 et donc le déplacement de la chaîne 36 le long de la glissière de guidage 32. 11 ajuste ensuite le positionnement des organes de fixation 34, de manière à amener ces derniers en prise avec le pied du rail 18a de l'appareil de voie 12. À l'issue de cette opération, le mécanisme d'arrimage 30 est dans la position transitoire illustrée sur la figure 8. Then, the operator releases the braking system 48 and controls the motor 46 to allow the driving of the drive wheel 42 and thus the movement of the chain 36 along the guide rail 32. 11 adjusts then the positioning of the fasteners 34, so as to bring them into engagement with the foot of the rail 18a of the track apparatus 12. At the end of this operation, the securement mechanism 30 is in the transient position illustrated in Figure 8.
[0054] Enfin, l’opérateur règle le positionnement de la vis 54 dans le pas de vis 56 en commandant le moteur associé jusqu’à ce que l’organe de fixation 34 exerce un effort de serrage suffisant sur le pied du rail 16a. De préférence, un témoin lumineux indique que la force de serrage est atteinte. [0055] Une fois l'appareil de voie 12 ainsi arrimé à la plateforme de support 24, il est possible de relever celle-ci dans la position des figures 1 et 2 pour le transport. Finally, the operator adjusts the positioning of the screw 54 in the thread 56 by controlling the associated motor until the fastener 34 exerts a sufficient clamping force on the foot of the rail 16a. Preferably, a light indicates that the clamping force is reached. Once the track device 12 and secured to the support platform 24, it is possible to raise it in the position of Figures 1 and 2 for transport.
[0056] Les opérations de déchargement se déroulent dans l'ordre inverse des opérations de chargement. The unloading operations take place in the reverse order of the loading operations.
[0057] Le cas échéant, un seul des deux organes de fixation 34 peut être positionné en prise avec un des rails 18 de l'appareil de voie 12, l'autre organe de fixation 34 restant dans une position libre le long de la glissière de guidage 32. De préférence, on prévoit, comme illustré, deux mécanismes d’arrimage 30 dont les organes de fixation 34 sont tournés transversalement l'un vers l'autre, c'est-à-dire de manière à ce que les zones d'accrochage 35 soient en regard l'une de l'autre. Grâce à cette disposition, lorsque les deux organes de fixation 34 sont en prise, l'appareil de voie est verrouillé latéralement. Where appropriate, only one of the two fasteners 34 may be positioned in engagement with one of the rails 18 of the track apparatus 12, the other fastener 34 remaining in a free position along the slide rail 32. Preferably, two lashing mechanisms 30 are provided as illustrated, the fasteners 34 of which are turned transversely towards each other, that is to say so that the zones fastening 35 are facing each other. With this arrangement, when the two fasteners 34 are engaged, the switchgear is locked laterally.
[0058] Dans un deuxième mode de réalisation de l’invention illustré aux figures 10 et 11, le mécanisme d’arrimage 30 diffère en ce que l’organe de liaison 31 est un ensemble formant parallélogramme 58 articulé comprenant au moins une bielle de transmission 62 reliée à la poutre supérieure 27, et un levier de transfert 60 relié à la poutre inférieure 29 commandé par un ensemble vis et écrou 64, de sorte que le déplacement de la poutre supérieure 27 soit cinématiquement lié au déplacement de la vis 65 dans l’écrou 67. In a second embodiment of the invention illustrated in Figures 10 and 11, the securing mechanism 30 differs in that the connecting member 31 is an assembly forming parallelogram 58 articulated comprising at least one transmission rod 62 connected to the upper beam 27, and a transfer lever 60 connected to the lower beam 29 controlled by a screw and nut 64, so that the displacement of the upper beam 27 is kinematically linked to the displacement of the screw 65 in the nut 67.
[0059] Plus précisément, dans le mode de réalisation illustré sur les figures, l’ensemble formant parallélogramme 58 comprend une bielle de transmission 62 de forme longitudinale, s’étendant selon une direction sensiblement parallèle à la direction d’extension des poutres supérieure 27 et inférieure 29. La bielle de transmission 62 est de préférence amincie à son centre de manière à l’alléger. La bielle de transmission 62 est reliée à chacune de ses extrémités libres 62a, 62b à deux leviers de transfert respectifs 60a, 60b. Cette liaison est effectuée par exemple à l’aide de deux axes 68 traversant à la fois la bielle de transmission 62 et les leviers de transfert 60a, 60b en s’étendant selon une direction normale la direction longitudinale de la bielle de transmission 62, c’est-à-dire dans le plan normal aux figures 10 et 11. [0060] Le premier levier de transfert 60a, ayant une forme en C ou en boomerang, est relié à une première extrémité à l’ensemble de vis et écrou 64 par un axe 66 s’étendant de façon normale à la direction longitudinale de la bielle de transmission 62, c’est-à-dire dans le plan normal aux figures 10 et 11. L’ensemble de vis et écrou 64 est lié à la poutre supérieure 27 de sorte que le mouvement de la vis 65 dans l’écrou 67 déplace le levier de transfert 60a en direction de la poutre supérieure 27. Du fait que la bielle de transmission 62 soit liée au levier de transfert 60a, elle est également déplacée vers le haut de la figure. More specifically, in the embodiment illustrated in the figures, the parallelogram assembly 58 comprises a transmission rod 62 of longitudinal shape, extending in a direction substantially parallel to the direction of extension of the upper beams 27. and lower 29. The transmission rod 62 is preferably thinned at its center so as to lighten it. The transmission rod 62 is connected to each of its free ends 62a, 62b to two respective transfer levers 60a, 60b. This connection is made for example by means of two shafts 68 passing through both the transmission rod 62 and the transfer levers 60a, 60b extending in a normal direction the longitudinal direction of the transmission rod 62, c that is to say in the plane normal to FIGS. 10 and 11. The first transfer lever 60a, having a C-shaped or boomerang shape, is connected at a first end to the screw and nut assembly 64 by an axis 66 extending in a normal manner to the longitudinal direction of the transmission rod 62, that is to say in the plane normal to Figures 10 and 11. The set of screws and nut 64 is connected to the upper beam 27 so that the movement of the screw 65 in the nut 67 moves the transfer lever 60a towards the upper beam 27. Because the transmission rod 62 is linked to the transfer lever 60a, it is also moved upwards in the figure.
[0061] Par ailleurs, la bielle de transmission 62 est également reliée à son extrémité 62a, toujours via le levier de transfert 60a, à la poutre supérieure 27, car le levier de transfert 60a est lié à la poutre supérieure 27 à son extrémité libre opposée à celle où il est lié à la bielle de transmission 62. Cette liaison se fait par l’intermédiaire d’un axe 70 s’étendant également de façon normale la direction longitudinale de la bielle de transmission 62 traversant le levier de transfert 60a, lui-même relié à un axe 72 traversant la poutre supérieure 27, ces deux axes 70 et 72 étant reliés par un tube 74. On notera que la liaison des deux axes 70 et 72 a été choisie en forme de tube de sorte à renforcer la structure, mais elle pourrait être d’une autre nature. Furthermore, the transmission rod 62 is also connected at its end 62a, still via the transfer lever 60a, to the upper beam 27, since the transfer lever 60a is connected to the upper beam 27 at its free end. opposite to that where it is connected to the transmission rod 62. This connection is via an axis 70 also extending in a normal manner the longitudinal direction of the transmission rod 62 passing through the transfer lever 60a, itself connected to an axis 72 passing through the upper beam 27, these two shafts 70 and 72 being connected by a tube 74. It will be noted that the connection of the two shafts 70 and 72 has been chosen in the form of a tube so as to reinforce the structure, but it could be of a different nature.
[0062] De façon symétrique, la bielle de transmission 62 est aussi reliée, à son extrémité opposée 62b, via le levier de transfert 60b (également en forme de C), à la poutre supérieure 27, car le levier de transfert 60b est également lié la poutre supérieure 27 par l’intermédiaire d’un axe 70 s’étendant également de façon normale la direction longitudinale de la bielle de transmission 62 traversant le levier de transfert 60a, lui-même relié à un axe 72 traversant la poutre supérieure 27, ces deux axes 70 et 72 étant reliés par un tube 74. Symmetrically, the transmission rod 62 is also connected, at its opposite end 62b, via the transfer lever 60b (also C-shaped) to the upper beam 27, since the transfer lever 60b is also connected the upper beam 27 via an axis 70 also extending in a normal manner the longitudinal direction of the transmission rod 62 passing through the transfer lever 60a, itself connected to an axis 72 passing through the upper beam 27 these two axes 70 and 72 being connected by a tube 74.
[0063] Dans une variante de ce deuxième mode de réalisation, non illustrée sur les figures, l’ensemble vis et écrou est remplacé par un ensemble vérin et corps de vérin. In a variant of this second embodiment, not shown in the figures, the screw and nut assembly is replaced by a cylinder assembly and cylinder body.
[0064] Par ailleurs, dans ce deuxième mode de réalisation illustré aux figures 10 et 11, le mécanisme d’arrimage 30 comprend deux poutres supérieures 27a, 27b reliées à une poutre inférieure 26, deux glissières de guidage 32, et deux organes de liaison 31 reliant respectivement chaque poutre supérieure 27a, 27b à la poutre inférieure 26, les organes de liaison 31 étant aptes à être pilotés de manière indépendante. Plus précisément, de préférence, les deux poutres supérieures 27a, 27b sont chacune d’une longueur correspondant à la moitié des poutres supérieures 27 illustrées dans le mode de réalisation précédent. [0065] Ainsi, on peut accrocher les deux extrémités de manière indépendante, ce qui évite un porte-à-faux, la force de serrage par crochet étant constante quelle que soit la position du crochet dans la glissière de guidage. L’utilisateur se trouve ainsi déchargé d’une contrainte de vigilance supplémentaire et peut se permettre d’être moins attentif. La sécurité de manipulation s’en retrouve donc accrue. [0066] Naturellement, les exemples représentés sur les figures et discutés ci- dessus ne sont donnés qu'à titre illustratif et non limitatif. Diverses variantes sont envisageables. Furthermore, in this second embodiment illustrated in Figures 10 and 11, the securing mechanism 30 comprises two upper beams 27a, 27b connected to a lower beam 26, two guide rails 32, and two connecting members 31 respectively connecting each upper beam 27a, 27b to the lower beam 26, the connecting members 31 being able to be controlled independently. More specifically, preferably, the two upper beams 27a, 27b are each of a length corresponding to half of the upper beams 27 illustrated in the previous embodiment. Thus, one can hang the two ends independently, which avoids a door overhang, the hook clamping force being constant regardless of the position of the hook in the guide rail. The user is thus relieved of additional vigilance and can afford to be less attentive. The security of handling is thus increased. Naturally, the examples shown in the figures and discussed above are given for illustrative and not limiting. Various variants are conceivable.
[0067] En particulier, la position de chargement et de déchargement de la plateforme n'est pas nécessairement horizontale, mais peut être au contraire inclinée, naturellement moins que la position de transport. In particular, the loading and unloading position of the platform is not necessarily horizontal, but may be on the contrary inclined, naturally less than the transport position.
[0068] Par ailleurs, en pratique, un même wagon de transport peut être équipé d’un nombre de mécanismes d'arrimage différent de celui qui a été décrit, répartis sur la longueur de la plateforme, afin de s'adapter localement à la configuration de l'appareil de voie. [0069] On pourra également prévoir d’autres moyens d’entraînement de l’organe de fixation, comme par exemple un chariot guidé par la glissière de guidage pourvue de chemins de roulement sur lesquels roulent des galets ou billes associés au chariot ou de glissement pour des pieds formés sur le chariot. Furthermore, in practice, the same transport car can be equipped with a number of securement mechanisms different from that described, distributed over the length of the platform, in order to adapt locally to the configuration of the switchgear. It may also provide other drive means of the fastener, such as a carriage guided by the guide rail provided with rolling tracks on which rollers or balls associated with the carriage or sliding for feet formed on the carriage.
[0070] 11 est explicitement prévu que l'on puisse combiner entre eux les différents modes de réalisation illustrés pour en proposer d'autres. It is explicitly provided that one can combine the different embodiments illustrated to propose others.
[0071] 11 est souligné que toutes les caractéristiques, telles qu’elles se dégagent pour un homme du métier à partir de la présente description, des dessins et des revendications attachées, même si concrètement elles n’ont été décrites qu’en relation avec d’autres caractéristiques déterminées, tant individuellement que dans des combinaisons quelconques, peuvent être combinées à d’autres caractéristiques ou groupes de caractéristiques divulguées ici, pour autant que cela n’a pas été expressément exclu ou que des circonstances techniques rendent de telles combinaisons impossibles ou dénuées de sens.
