Abstract

The invention relates to a car (1) that comprises an elongated platform (10) for conveying loads on a railway and a covering roof (60), the roof being located above loading and unloading devices (30) arranged on the platform. In order to facilitate the use of the car both in the presence of a powered catenary system and in the presence of overhead equipment for loading the car, the roof includes two fixed roof members (721, 722) covering the first two longitudinal portions (10A, 10B) of the platform, and four mobile roof members (741, 761, 742, 762) each movable between an extended position, in which the mobile roof members protrude from the fixed roof members in the longitudinal direction and thus cover four second longitudinal portions (10C, 10D, 10E, 10F) and a stowed position in which each mobile roof member and the corresponding fixed roof member thereof are stacked along the vertical direction so that the second portions of the platform are uncovered towards the top.

Description

WAGON DE MANUTENTION DE CHARGES LOURDES, NOTAMMENT DE RAILS, ET UTILISATION D'UN TEL WAGON EN PRESENCE D'UNE WAGON FOR HANDLING HEAVY LOADS, IN PARTICULAR RAILS, AND USE OF SUCH A WAGON IN THE PRESENCE OF A
CATENAIRECATENARY
La présente invention concerne un wagon de manutention de charges lourdes telles que de rails. L'invention concerne également l'utilisation d'un tel wagon sur une voie ferrée pourvue d'une caténaire.The present invention relates to a wagon for handling heavy loads such as rails. The invention also relates to the use of such a car on a railroad provided with a catenary.
A des fin de maintenance d'une voie ferrée, il est fréquemment nécessaire de transporter des charges lourdes, en particulier des rails neufs, depuis une station de maintenance jusqu'à un site d'intervention le long de la voie ferrée. On utilise généralement à cet effet des wagons plats, c'est-à-dire des wagons dont le plancher, posé sur un châssis, forme une simple plate-forme sans caisse, ni toit. Pour permettre de charger et décharger les rails, ce genre de wagon est souvent équipé d'un ou de plusieurs appareils motorisés de soulèvement, qui permettent de déplacer les rails à l'extérieur de la plate-forme.At the end of maintenance of a railway, it is frequently necessary to transport heavy loads, in particular new rails, from a maintenance station to a site of intervention along the railway. For this purpose, flat cars are generally used, that is wagons whose floor, placed on a chassis, forms a simple platform without a box or a roof. To enable the loading and unloading of the rails, this type of wagon is often equipped with one or more motorized lifting devices, which allow the rails to be moved outside the platform.
Toutefois, pour des raisons de sécurité, liées par exemple à la norme française NF F 58-002 et au projet de norme internationale prEN 14033-1 , l'utilisation de tels appareils de soulèvement le long d'une voie ferrée associée à une caténaire oblige à couper l'alimentation électrique de la caténaire, sauf à ce qu'un toit continu recouvre totalement la plate-forme du wagon, en particulier les appareils de soulèvement. En principe, l'agencement d'un tel toit continu, notamment sous forme d'un grand panneau rigide couvrant toute la plate-forme, est concevable, comme cela est proposé par exemple dans GB-A-318 304. Mais, en pratique, cela pose un problème majeur : la présence d'un tel toit empêche alors le chargement, sur la plate-forme du wagon, d'un lot de rails à l'aide d'une installation aérienne, telle qu'un pont roulant ou un portique, utilisée couramment dans les stations de maintenance, étant entendu que dans ces stations, les caténaires ne sont pas admises. Le but de la présente invention est de proposer à un wagon de manutention, qui puisse être utilisé avec autant de facilité en présence d'une caténaire alimentée en électricité le long d'une voie de chemin de fer, qu'en combinaison avec une installation aérienne pour charger ce wagon, notamment dans une station de maintenance. A cet effet, l'invention a pour objet un wagon de manutention de charges lourdes telles que des rails, comportant, d'une part, une plate-forme allongée de transport des charges sur une voie ferrée, cette plate-forme étant munie d'au moins un dispositif de chargement et déchargement des charges, et, d'autre part, une toiture de couverture de la plate-forme, qui est située au dessus du ou des dispositifs de chargement et déchargement, et une toiture comprenant, à la fois, au moins un élément de toit fixe, qui est lié rigidement à la plate-forme et qui couvre une première partie longitudinale de la plate-forme, et au moins un élément de toit mobile qui est déplaçable par rapport à l'élément de toit fixe entre une position déployée, dans laquelle l'élément de toit mobile s'étend, au moins pour l'essentiel, en saillie de l'élément de toit fixe suivant la direction longitudinale de la plate-forme et couvre ainsi une deuxième partie longitudinale de la plate-forme, adjacente à la première partie de la plate-forme, et une position escamotée, dans laquelle l'élément de toit mobile et l'élément de toit fixe sont, au moins pour l'essentiel, superposés suivant la verticale de telle sorte que la deuxième partie de la plate-forme est découverte vers le haut.However, for safety reasons, linked for example to the French standard NF F 58-002 and the draft international standard prEN 14033-1, the use of such lifting devices along a railroad associated with a catenary requires the power supply to be cut off from the catenary, except that a continuous roof completely covers the platform of the wagon, in particular lifting devices. In principle, the arrangement of such a continuous roof, especially in the form of a large rigid panel covering the entire platform, is conceivable, as proposed for example in GB-A-318 304. But, in practice , this poses a major problem: the presence of such a roof then prevents loading, on the platform of the wagon, a lot of rails using an overhead installation, such as an overhead crane or a gantry, commonly used in maintenance stations, it being understood that in these stations catenaries are not allowed. The object of the present invention is to propose to a handling car, which can be used with such ease in the presence of a catenary supplied with electricity along a railroad track, that in combination with an installation to load this wagon, in particular in a maintenance station. To this end, the subject of the invention is a wagon for handling heavy loads such as rails, comprising, on the one hand, an elongate platform for transporting loads on a railway track, this platform being provided with at least one load loading and unloading device, and, secondly, a roof covering of the platform, which is situated above the loading or unloading device or devices, and a roof comprising, at the at least one fixed roof element, which is rigidly connected to the platform and which covers a first longitudinal part of the platform, and at least one movable roof element which is displaceable relative to the fixed roof between an extended position, in which the movable roof element extends, at least substantially, projecting from the fixed roof element in the longitudinal direction of the platform and thus covers a second part longitudinal of the platform, adjacent to the first part of the platform, and a retracted position, in which the movable roof element and the fixed roof element are, at least for the most part, superimposed vertically so that the second part of the platform is discovered up.
L'idée à la base de l'invention est de contourner l'inconvénient lié à la présence permanente d'une toiture continue couvrant la plate-forme du wagon, en proposant une toiture modulaire, dont au moins un des éléments de toit est mobile par rapport à un élément de toit fixe, comme défini ci-dessus. Lorsque le ou les éléments de toit mobiles sont dans leur position escamotée, une ou plusieurs parties longitudinales de la plate-forme sont accessibles verticalement par le haut, ce qui permet alors d'utiliser une installation aérienne pour charger la plate-forme, typiquement lorsque le wagon est à une station de maintenance : par exemple, un pont roulant, c'est-à-dire une structure qui se déplace sur deux chemins de roulement parallèles aériens et qui comportent des poutres permettant le déplacement d'un appareil de levage de charges lourdes à manutentionner, peut alors être utilisé pour placer sur la plate-forme un lot de rails, ce lot de rails étant introduit entre la plate-forme et la toiture de manière latérale au wagon tandis que les chaînes de soulèvement des rails, actionnées par le pont roulant, s'étendent verticalement à travers la ou les zones de toiture dégagées par le ou les éléments de toit mobiles en position escamotée. Lorsque le ou les éléments de toit mobiles sont dans leur position déployée, ils prolongent le ou les éléments de toit fixes dans la direction longitudinale de la plate-forme et forment ainsi, conjointement avec ce ou ces éléments de toit fixes, une toiture continue couvrant en longueur la plate-forme, en particulier son ou ses dispositifs de chargement et déchargement, ce qui permet de satisfaire les normes de sécurité mentionnées plus haut pour que les caténaires restent alimentées en électricité pendant la manutention des charges.The idea behind the invention is to circumvent the disadvantage associated with the permanent presence of a continuous roof covering the platform of the car, proposing a modular roof, at least one of the roof elements is movable relative to a fixed roof element, as defined above. When the movable roof element (s) are in their retracted position, one or more longitudinal parts of the platform are vertically accessible from the top, which then makes it possible to use an aerial installation to load the platform, typically when the wagon is at a maintenance station: for example, a traveling crane, that is to say a structure which moves on two parallel parallel airways and which comprise beams allowing the displacement of a lifting apparatus of heavy loads to be handled, can then be used to place on the platform a lot of rails, this batch of rails being introduced between the platform and the roof laterally to the wagon while the lifting chains rails, actuated by the traveling crane, extend vertically through the roof area (s) cleared by the movable roof element (s) in the retracted position. When the movable roof element (s) are in their deployed position, they extend the fixed roof element (s). in the longitudinal direction of the platform and thus form, together with this or these fixed roof elements, a continuous roof covering the platform in length, in particular its or its loading and unloading devices, which makes it possible to satisfy the safety standards mentioned above for the catenaries to remain energized during load handling.
Pour faciliter l'utilisation du wagon conforme à l'invention, ce dernier comporte avantageusement des moyens motorisés d'entraînement du ou de chaque élément de toit mobile entre ses positions déployée et escamotée. De préférence, ces moyens motorisés incluent un système de débrayage manuel, qui permet de désaccoupler les moyens motorisés vis-à-vis de l'élément de toit mobile et ainsi de déplacer manuellement cet élément de toit jusqu'à l'une de ses deux positions extrêmes, par exemple en cas de disfonctionnement des moyens motorisés ou de blocage de l'élément de toit mobile lors de son déplacement. Pour renforcer davantage la sécurité d'utilisation du wagon conforme à l'invention, ce dernier comporte en outre avantageusement des moyens de commande, adaptés pour désactiver le ou les dispositifs de chargement et déchargement lorsque le ou au moins un des éléments de toit mobile n'est pas dans sa position déployée. Dans ces conditions, l'utilisateur est forcé de déployer tous les éléments de toit mobiles avant de pouvoir faire fonctionner le ou les dispositifs de chargement et déchargement, limitant notamment les risques d'accident en présence d'une caténaire.To facilitate the use of the wagon according to the invention, the latter advantageously comprises motorized means for driving the or each movable roof element between its deployed and retracted positions. Preferably, these motorized means include a manual disengagement system, which allows uncoupling the motorized means vis-à-vis the movable roof element and thus move manually this roof element to one of its two extreme positions, for example in case of malfunction of the motorized means or blocking of the movable roof element during its movement. To further enhance the safety of use of the wagon according to the invention, the latter advantageously further comprises control means adapted to disable the loading or unloading device or devices when the or at least one of the movable roof elements is not in his deployed position. Under these conditions, the user is forced to deploy all movable roof elements before being able to operate the loading or unloading device or devices, limiting in particular the risk of accident in the presence of a catenary.
Des caractéristiques avantageuses du wagon conforme à l'invention, prises isolément ou suivant toutes les combinaisons techniquement possibles, sont spécifiées aux revendications dépendantes 4 à 9.Advantageous features of the wagon according to the invention, taken individually or in any technically possible combination, are specified in the dependent claims 4 to 9.
L'invention a également pour objet une utilisation d'un wagon, tel que défini ci-dessus, sur une voie ferrée pourvue d'une caténaire, telle que définie à la revendication 10.The invention also relates to a use of a wagon, as defined above, on a railroad provided with a catenary, as defined in claim 10.
L'utilisation conforme à l'invention respecte les critères édictés par les normes mentionnées plus haut.The use according to the invention complies with the criteria enunciated by the standards mentioned above.

- les figures 7 à 9 sont des perspectives schématiques, illustrant respectivement trois étapes successives d'utilisation du wagon.- Figures 7 to 9 are schematic perspectives illustrating respectively three successive stages of use of the wagon.
Sur les figures 1 à 9 est présenté un wagon 1 de manutention de rails 2, ces derniers n'étant représentés qu'à la figure 2.FIGS. 1 to 9 show a wagon 1 for handling rails 2, the latter only being shown in FIG.
Comme bien visible sur les figures 1 et 2, le wagon 1 comporte une plateforme 10 formant le plancher du wagon et reposant sur un châssis 12 en appui sur le sol par l'intermédiaire de quatre trains 14 de roues 16 à même de rouler sur deux rails R d'une voie ferrée. Par commodité, la suite de la description est orientée par rapport à ces railsAs can be seen clearly in FIGS. 1 and 2, the wagon 1 comprises a platform 10 forming the floor of the wagon and resting on a frame 12 supported on the ground by means of four sets of wheels 14 capable of rolling on two wheels. rails R of a railway. For convenience, the following description is oriented relative to these rails
R, en considérant que ceux-ci s'étendent sur une surface plane horizontale. Ainsi, la plate-forme 10 comporte un corps principal horizontal 18, qui présente une forme extérieure globalement parallélépipédique dont la direction longitudinale est parallèle aux rails R. A chacune de ses extrémités longitudinales, que l'on qualifiera par la suite d'extrémités avant et arrière pour faciliter la présente description, avec la convention arbitraire que la direction avant est dirigée vers la gauche sur les figures 1 , 4 et 7 à 9, le corps de plate-forme 18 est muni d'une paire de buttoirs 20 et d'un ensemble de ridelle 22. Sur chacun de ses côtés latéraux, le corps de plate-forme 18 est muni de ranchers 24, ici au nombre de cinq. De manière connue en soi, les ensembles de ridelle 22 et les ranchers 24 permettent de retenir en place le chargement constitué par les rails 2, notamment lorsque la plate-forme 10 roule sur les rails R. De plus, afin de mieux assujettir le chargement constitué par les rails 2, la face supérieure 18A du corps de plate-forme 18 est équipée de traverses 26 qui sont réparties suivant la longueur de la plate-forme 10 et sur lesquelles reposent les rails 2, comme représenté sur la figure 2. La plate-forme 10 est également équipée de deux dispositifs 30 permettant, d'une part, de décharger du corps de plate-forme 18 les rails 2 et, d'autre part, de charger sur le corps de plate-forme des charges du même type que les rails 2 une fois que ces derniers ont été déchargés. Les deux dispositifs 30 sont répartis suivant la longueur de la plate-forme 10, en étant respectivement situés au niveau des quarts avant et arrière du corps de plate-forme 18. L'un de ces dispositifs 30 est représenté seul à la figure 3.R, considering that these extend on a horizontal flat surface. Thus, the platform 10 comprises a horizontal main body 18, which has a generally parallelepipedal external shape whose longitudinal direction is parallel to the rails R. At each of its longitudinal ends, which will be described hereafter as front ends and rearwardly to facilitate the present description, with the arbitrary convention that the forward direction is directed to the left in FIGS. 1, 4 and 7 to 9, the deck body 18 is provided with a pair of buffers 20 and A set of side walls 22. On each of its lateral sides, the platform body 18 is provided with stanchions 24, here five in number. In a manner known per se, the sideboard assemblies 22 and the stanchions 24 allow to retain the load constituted by the rails 2, especially when the platform 10 rolls on the rails R. In addition, in order to better secure the load constituted by the rails 2, the upper face 18A of the platform body 18 is equipped with sleepers 26 which are distributed along the length of the platform 10 and on which the rails 2 rest. as shown in FIG. 2. The platform 10 is also equipped with two devices 30 making it possible, on the one hand, to unload from the platform body 18 the rails 2 and, on the other hand, to load on the platform body loads of the same type as the rails 2 once they have been unloaded. The two devices 30 are distributed along the length of the platform 10, being located respectively at the front and rear quarter of the platform body 18. One of these devices 30 is shown alone in Figure 3.
Chaque dispositif 30 comporte un pied cylindrique vertical 32 qui s'étend vers le haut depuis la région centrale d'une plaque de support inférieure 34 horizontale, en étant lié rigidement à celle-ci. La plaque 34 est rapportée et assemblée à demeure à la face supérieure 18A du corps de plate-forme 18. Dans sa partie supérieure, le pied 32 supporte un moyeu tournant 36, qui entoure le pied et qui est relié à ce dernier de manière à pouvoir tourner autour du pied par pivotement autour d'un axe géométrique vertical 38.Each device 30 has a vertical cylindrical foot 32 which extends upwardly from the central region of a horizontal lower support plate 34, being rigidly connected thereto. The plate 34 is attached and permanently joined to the upper face 18A of the platform body 18. In its upper part, the foot 32 supports a rotating hub 36, which surrounds the foot and which is connected thereto so as to being able to rotate around the foot by pivoting about a vertical geometric axis 38.
Chaque dispositif 30 comporte également un bras allongé 40, ici sous forme d'une poutre à section transversale en I, qui s'étend radialement à l'axe 38 depuis le moyeu 36, en étant lié rigidement à ce moyeu. Chaque bras 40 est muni d'un chariot mobile 42 déplaçable le long du bras entre les deux extrémités longitudinales de ce dernier, sous l'action d'un moteur électrique d'entraînement 44. Chaque chariot 42 porte un palan suspendu 46 qui, de façon connue en soi et non détaillée ici, intègre une chaîne de soulèvement d'une charge, non visible sur les figures, terminée par un crochet de levage 48.Each device 30 also comprises an elongate arm 40, here in the form of a beam with an I-shaped cross-section, which extends radially to the axis 38 from the hub 36, being rigidly connected to this hub. Each arm 40 is provided with a movable carriage 42 movable along the arm between the two longitudinal ends of the latter, under the action of an electric drive motor 44. Each carriage 42 carries a suspended hoist 46 which, in a manner known per se and not detailed here, incorporates a lifting chain of a load, not visible in the figures, terminated by a lifting hook 48.
Chaque dispositif 30 est en outre muni d'un pupitre de commande 50 qui permet à un utilisateur d'actionner le moteur 44 pour entraîner le chariot 42 en translation le long du bras 40. Avantageusement, chaque dispositif 30 est également muni de moyens de détection de la position relative des composants mobiles du dispositif par rapport au pied 32, ces moyens étant reliés au pupitre de commande 50. Ainsi, des éléments de détection, non visibles sur les figures car protégés par un carter 52, permettent de détecter la position angulaire du moyeu 36 autour du pied 32. De même, un capteur 54 est embarqué sur le chariot 42 de manière que sa présence soit détectée par des détecteurs de fin de course 56, respectivement situés aux deux extrémités longitudinales du bras 40.Each device 30 is further provided with a control panel 50 which allows a user to actuate the motor 44 to drive the carriage 42 in translation along the arm 40. Advantageously, each device 30 is also provided with detection means the relative position of the mobile components of the device relative to the foot 32, these means being connected to the control panel 50. Thus, detection elements, not visible in the figures because protected by a housing 52, can detect the angular position hub 36 also around the foot 32. Similarly, a sensor 54 is embedded on the carriage 42 so that its presence is detected by end-of-travel detectors 56, respectively located at the two longitudinal ends of the arm 40.
Le wagon 1 comporte en outre une toiture 60 reliée à la plate-forme 10 par trois pieds verticaux répartis régulièrement suivant la longueur de la plate-forme, à savoir un pied avant 62 situé à l'extrémité avant du corps de plate-forme 18, un pied intermédiaire 64, situé au milieu du corps de plate-forme, et un pied arrière 66 situé à l'extrémité arrière du corps de plate-forme. La toiture 60 et les pieds 62, 64 et 66 sont représentés de manière isolée, dans leur configuration d'assemblage, à la figure 4.The wagon 1 further comprises a roof 60 connected to the platform 10 by three vertical feet distributed regularly along the length of the platform, namely a front foot 62 located at the front end of the platform body 18 , an intermediate foot 64, located in the middle of the deck body, and a rear foot 66 located at the rear end of the deck body. The roof 60 and the feet 62, 64 and 66 are shown in isolation, in their assembly configuration, in FIG. 4.
Chaque pied 62, 64, 66 s'étend vers le haut depuis une plaque d'appui inférieure 63, 65, 67 horizontale qui est rapportée et solidarisée fermement à la face supérieure 18A du corps de plate-forme 18. Les extrémités supérieures des trois pieds sont reliées les unes aux autres par une poutre horizontale 68 qui s'étend sensiblement sur toute la longueur de la plate-forme 10 et qui, comme bien visible à la figure 5, présente une coupe transversale en I. Ainsi, la poutre 68 est constituée d'une moitié de poutre avant 681, qui relie les pieds 62 et 64, et d'une moitié de poutre arrière 682, qui relie les pieds 64 et 66. En pratique, la poutre 68 peut être réalisée d'une seule pièce ou, au contraire, résulter de l'assemblage rigide de deux poutres élémentaires correspondant respectivement aux deux moitiés de poutre 681 et 682.Each foot 62, 64, 66 extends upwardly from a horizontal lower support plate 63, 65, 67 which is attached and secured firmly to the upper face 18A of the platform body 18. The upper ends of the three feet are connected to each other by a horizontal beam 68 which extends substantially over the entire length of the platform 10 and which, as can be seen in FIG. 5, has a cross section in I. Thus, the beam 68 consists of a front beam half 68 1 , which connects the feet 62 and 64, and a rear beam half 68 2 , which connects the feet 64 and 66. In practice, the beam 68 can be made of one piece or, conversely, result from the rigid assembly of two elementary beams respectively corresponding to the two beam halves 681 and 682.
A chacune de ses extrémités longitudinales, la poutre 68 est munie d'une plaque transversale de fermeture 70.At each of its longitudinal ends, the beam 68 is provided with a transverse closure plate 70.
Chaque moitié de poutre 681, 682 est associée à trois panneaux de toit, à savoir un panneau de toit fixe 721 ; 722 et deux panneaux de toit mobiles, respectivement avant 74i, 742 et arrière 76i, 762. Ces différents panneaux sont globalement horizontaux, étant précisé que, dans un plan transversal à la plateforme 10, ils présentent une section globalement bombée vers le haut, comme bien visible aux figures 2 et 5. Chaque panneau 72!, 722 est qualifié de fixe dans le sens où il est relié rigidement à la plate-forme 10 par un potelet vertical 78i, 782 solidaire de la moitié de poutre correspondante 681, 682, situé au milieu de cette moitié de poutre. L'extrémité supérieure de chaque potelet 78i, 782 est solidarisée à la face inférieure du panneau fixe 72i, 722, et ce par tout moyen approprié, tandis que son extrémité inférieure forme une interface mécanique 8O1, 8O2 à même d'être fixé à l'extrémité supérieure 32A d'un des pieds 32 des dispositifs de chargement et déchargement 30, comme bien visible sur la figure 2. Les panneaux fixes 72i et 722 s'étendent ainsi à demeure respectivement au-dessus d'un des dispositifs 30, en couvrant des parties longitudinales respectives 10A et 10B de la plate-forme 10, au niveau desquelles sont respectivement disposés les deux dispositifs 30. Avantageusement, chaque panneau fixe 72i, 722 présente une longueur suffisante pour couvrir en totalité le bras 40 du dispositif correspondant 30 lorsque ce bras s'étend suivant la direction longitudinale de la plate-forme 10, comme représenté sur la figure 1.Each half of beam 68 1 , 68 2 is associated with three roof panels, namely a fixed roof panel 72 1; 72 2 and two movable roof panels, respectively before 74i, 74 2 and rear 76i, 76 2 . These various panels are generally horizontal, being specified that, in a plane transverse to the platform 10, they have a generally domed upward section, as clearly visible in Figures 2 and 5. Each panel 72 ! , 72 2 is described as fixed in the sense that it is rigidly connected to the platform 10 by a vertical post 78i, 78 2 integral with the corresponding half of the beam 681, 68 2 , located in the middle of this half of beam. The upper end of each post 78i 78 2 is secured to the face the lower end of the fixed panel 72i, 72 2 , by any appropriate means, while its lower end forms a mechanical interface 8O1, 8O2 able to be fixed to the upper end 32A of one of the feet 32 of the loading devices and unloading 30, as clearly visible in Figure 2. The fixed panels 72i and 72 2 thus extend permanently above one of the devices 30, covering respective longitudinal portions 10A and 10B of the platform 10, at which are respectively arranged the two devices 30. Advantageously, each fixed panel 72i, 72 2 has a length sufficient to completely cover the arm 40 of the corresponding device 30 when the arm extends in the longitudinal direction of the plate 10, as shown in FIG.
Chacun des panneaux 741 ; 742, 76i, 762 est qualifié de mobile dans le sens où il est déplaçable par rapport à son panneau fixe associé 72i, 722 suivant la direction longitudinale de la plate-forme 10. A cet effet, chacun de ces panneaux mobiles est porté par un chariot de déplacement, seul le chariot du panneau 1A\ étant référencé sur les figures, sous la référence 82, comme représenté sur les figures 2 et 4 à 6. Par la suite, seul le chariot 82 va être décrit plus en détail, étant entendu que les chariots respectifs des autres panneaux mobiles 742, 76i, 762 présentent une structure identique. Le chariot 82 présente une forme globale allongée suivant la direction longitudinale de la plate-forme 10 et comporte deux pièces d'extrémité longitudinale, à savoir une pièce d'extrémité avant 82A et une pièce d'extrémité arrière non visible sur les figures, respectivement solidarisées aux bords avant et arrière du panneau 74Ï . Chaque pièce d'extrémité est munie de deux paires latérales de galets de roulement sur, respectivement, les parties latérales de l'aile supérieure horizontale 68A de la poutre 68, comme représenté à la figure 6 sur laquelle sont visibles les galets 82B de la paire gauche associée à la pièce d'extrémité avant 82A. Les deux pièces d'extrémité longitudinale du chariot 82 sont reliées par, d'une part, un longeron 82C et par une crémaillère 82D. Cette crémaillère 82D est en prise d'engrènement avec une roue dentée 84 liée en rotation à l'arbre de sortie horizontal d'un moteur électrique réversible 86 porté par un support 88 solidarisé fixement à la poutre 68. Lorsque le moteur 86 est actionné, il entraîne en rotation sur elle-même la roue 84, ce qui entraîne en translation horizontale, par rapport à la poutre 68 et donc par rapport à la plateforme 10, la crémaillère 82D et, par là, l'ensemble du chariot 82 ainsi que le panneau 1A\ qui est solidaire de ce chariot, et ce vers l'avant ou vers l'arrière selon le sens d'entraînement du moteur. Avantageusement, le chariot 82 est associé à un détecteur 90 de position du chariot : par exemple, ce détecteur est solidarisé fixement à la poutre 68 de telle sorte qu'un élément de détection de ce détecteur, par exemple un galet, soit sollicité par le chariot 82, notamment par une palette 82E liée rigidement à la pièce d'extrémité avant 82A, lorsque le panneau 1A\ est translaté au maximum vers l'arrière, tandis que ce même élément de détection est sollicité par la pièce d'extrémité arrière du chariot 82 lorsque le panneau 1A\ est translaté au maximum vers l'avant. Autrement dit, le détecteur 90 permet de détecter les fins de course du panneau 74i vers l'avant ou vers l'arrière le long de la poutre 68.Each of the panels 74 1; 74 2, 76i, 76 2 is qualified mobile in the sense that it is movable relative to its associated fixed panel 72i, 72 2 in the longitudinal direction of the platform 10. For this purpose, each of these movable panels is carried by a carriage, only the carriage of the panel 1A \ being referenced in the figures, under the reference 82, as shown in Figures 2 and 4 to 6. Thereafter, only the carriage 82 will be described in more detail , it being understood that the respective carriages of the other movable panels 74 2 , 76i, 76 2 have an identical structure. The carriage 82 has an overall shape elongate in the longitudinal direction of the platform 10 and has two longitudinal end pieces, namely a front end piece 82A and a rear end piece not visible in the figures, respectively secured to the front and rear edges of the panel 74 Ï. Each end piece is provided with two lateral pairs of rollers on, respectively, the lateral portions of the upper horizontal wing 68A of the beam 68, as shown in FIG. 6 on which are visible the rollers 82B of the pair left associated with the front end piece 82A. The two longitudinal end pieces of the carriage 82 are connected by, on the one hand, a spar 82C and by a rack 82D. This rack 82D meshingly engages with a toothed wheel 84 rotatably connected to the horizontal output shaft of a reversible electric motor 86 carried by a support 88 fixedly secured to the beam 68. When the motor 86 is actuated, it drives in rotation on itself the wheel 84, which results in horizontal translation, with respect to the beam 68 and therefore with respect to the platform 10, the rack 82D and, thereby, the assembly of the carriage 82 as well as the panel 1A \ which is integral with this carriage, and this towards the forward or backward depending on the drive direction of the motor. Advantageously, the carriage 82 is associated with a detector 90 of position of the carriage: for example, this detector is firmly fixed to the beam 68 so that a detection element of this detector, for example a roller, is requested by the trolley 82, in particular by a pallet 82E rigidly connected to the front end piece 82A, when the panel 1A \ is translated at the maximum rearward, while the same detection element is urged by the rear end piece of the carriage 82 when the panel 1A \ is translated to the maximum forward. In other words, the detector 90 makes it possible to detect the limit switches of the panel 74i forwards or backwards along the beam 68.
Le wagon 1 comporte également une armoire de commande 92, visible de manière non détaillée à la figure 1 , qui permet de commander l'actionnement des moteurs, dont le moteur 86, respectivement associés aux chariots de déplacement des panneaux mobiles 741 ; 7A2, 76i et 762. Dans le mode de réalisation considéré ici, l'armoire 92 est supportée par le châssis 12, de manière à être accessible à un utilisateur au niveau d'un des côtés latéraux de la plate-forme 10. En plus d'être reliée au moteur 86 associé au panneau 74i et aux moteurs analogues associés aux autres panneaux mobiles 742, 76i et 762 à des fins d'actionnement de ces quatre moteurs, l'armoire de commande 92 est reliée aux dispositifs de chargement et déchargement 30, plus précisément à leur pupitre de commande 50, à des fins de désactivation réversible de ces dispositifs. Plus précisément, l'armoire de commande 92 permet, selon la position des panneaux mobiles 74i, 742, 76i et 762, d'empêcher l'actionnement des moteurs 44, par exemple en coupant leur alimentation électrique. Cet aspect sécuritaire du wagon 1 va être décrit plus en détail ci-après, dans le cadre de la description d'un exemple d'utilisation du wagon en regard des figures 1 et 7 à 9, étant remarqué que, pour des raisons de clarté, de nombreux détails de réalisation du wagon 1 ne sont pas repris ou bien sont indiqués uniquement de manière très schématique sur les figures 7 à 9. Initialement, on considère que le wagon 1 est dans la configuration représentée à la figure 1. Les quatre panneaux mobiles 74i, 742, 76i et 762 sont alors dans des positions respectives escamotées vis-à-vis de leur panneau fixe correspondant 72i, 722 : les panneaux avant 74i et 742 sont alors dans un état translaté au maximum vers l'arrière tandis que les panneaux arrières 76i et 762 sont dans un état translaté au maximum vers l'avant. Dans ces conditions, les panneaux 74i et 76i sont, quasiment intégralement, disposés au dessous du panneau fixe 72i, chacun par superposition suivant la verticale. Il en est de même pour les panneaux 742 et 762 vis-à-vis de leur panneau fixe 722. Il en résulte que la partie d'extrémité avant et la partie d'extrémité arrière de la moitié de poutre 681, ainsi que la partie d'extrémité avant et la partie d'extrémité arrière de la moitié de poutre 682 ne sont pas recouvertes par les panneaux mobiles, de telle sorte que les parties longitudinales 1 OC, 10D, 10E et 10F de la plate-forme 10, respectivement situées à l'aplomb vertical de ces parties d'extrémité des deux moitiés de poutre, sont découvertes vers le haut, tandis que, eu égard à la présence permanente des panneaux fixes 72i et 722, les parties de plate-forme 10A et 10B, respectivement interposées de manière adjacente entre les parties 10C et 10D et entre les parties 10E et 10F, sont quant à elles recouvertes par ces panneaux fixes. Autrement dit, dans cette configuration du wagon 1 , la toiture 60, qui inclut tous les panneaux de toit 72i, 722, 74i, 742, 76i et 762, ne couvrent pas la plateforme 10 sur toute sa longueur, mais présentent trois zones longitudinales ajourées Z, réparties suivant la longueur de la plate-forme et respectivement situées à l'aplomb vertical de la partie de plate-forme 10C, à l'aplomb vertical des parties de plate-forme cumulées 10D et 10E en étant centrée sur le pied intermédiaire 64, et à l'aplomb vertical de la partie de plate-forme 10F. Des chaînes ou des moyens de levage analogues peuvent ainsi être introduits au travers de ces trois zones ajourées Z, en particulier afin de charger sur la plateforme 10 les rails 2, non représentés sur les figures 7 à 9, à l'aide d'un appareil de manutention aérien, tel qu'un portique ou un pont roulant, les rails 2 étant introduits entre la plate-forme 10 et les panneaux de la toiture 60 de manière latérale au wagon 1. Typiquement, une telle opération de chargement aérien du wagon 1 est effectuée alors que ce dernier est à l'arrêt dans une station de maintenance dédiée à cet usage.The wagon 1 also comprises a control cabinet 92, not shown in FIG. 1, which makes it possible to control the actuation of the motors, including the motor 86, respectively associated with the moving carriages of the movable panels 74 1; 7A 2 , 76i and 76 2 . In the embodiment considered here, the cabinet 92 is supported by the frame 12, so as to be accessible to a user at one of the lateral sides of the platform 10. In addition to being connected to the engine Associated with the other panels 74 2 , 76i and 76 2 for the purpose of actuating these four motors, the control cabinet 92 is connected to the loading and unloading devices 30, more precisely at their control panel 50, for purposes of reversible deactivation of these devices. More specifically, the control cabinet 92 allows, depending on the position of the movable panels 74i, 74 2 , 76i and 76 2 , to prevent the actuation of the motors 44, for example by cutting off their power supply. This safety aspect of the car 1 will be described in more detail below, in the context of the description of an example of use of the wagon with reference to FIGS. 1 and 7 to 9, being noted that, for the sake of clarity , many details of realization of the car 1 are not included or are shown only very schematically in Figures 7 to 9. Initially, it is considered that the car 1 is in the configuration shown in Figure 1. The four movable panels 74i, 74 2 , 76i and 76 2 are then in respective positions retracted vis-à-vis their corresponding fixed panel 72i, 72 2 : the front panels 74i and 74 2 are then in a state translated at most rearward while the rear panels 76i and 76 2 are in a state translated to the maximum forward. Under these conditions, the panels 74i and 76i are, almost entirely, arranged below the fixed panel 72i, each by superposition along the vertical. It is the same for panels 74 2 and 76 2 vis-à-vis their fixed panel 72 2 . As a result, the front end portion and the rear end portion of the beam half 68 1 , as well as the front end portion and the rear end portion of the beam half 68 2 are not covered by the movable panels, so that the longitudinal portions 1 OC, 10D, 10E and 10F of the platform 10, respectively vertically plumb these end portions of the two beam halves, are discovered to at the top, whereas, in view of the permanent presence of the fixed panels 72i and 72 2 , the deck portions 10A and 10B, respectively interposed adjacently between the parts 10C and 10D and between the parts 10E and 10F, are as for them covered by these fixed panels. In other words, in this configuration of the car 1, the roof 60, which includes all the roof panels 72 1 , 72 2 , 74 1 , 74 2 , 76 1 and 76 2 , do not cover the platform 10 over its entire length, but have three longitudinal perforated zones Z, distributed along the length of the platform and respectively vertically plumb to the deck portion 10C, vertically plumb with the cumulative deck portions 10D and 10E being centered on the intermediate foot 64, and vertically plumb with the deck portion 10F. Similar chains or lifting means can thus be introduced through these three perforated zones Z, in particular in order to load on the platform 10 the rails 2, not shown in FIGS. 7 to 9, using a aerial handling apparatus, such as a gantry crane or a traveling crane, the rails 2 being introduced between the platform 10 and the roof panels 60 laterally to the car 1. Typically, such an air loading operation of the wagon 1 is carried out while the latter is at a standstill in a maintenance station dedicated for this purpose.
Dans un deuxième temps, on considère que le wagon 1 quitte la station de maintenance précitée, en roulant sur les rails R, jusqu'à atteindre un site d'intervention le long de la voie ferrée des rails R. Au niveau de ce site d'intervention, les rails 2 stockés sur la plate-forme 10 sont par exemple à décharger et, pour ce faire, l'utilisateur va se servir des dispositifs 30. Toutefois, la mise en mouvement de ces dispositifs 30 est, pour des raisons de sécurité, en particulier liées à la norme NF F 58-002 ou au projet de norme prEN 14033-1 , incompatible avec la présence d'une caténaire C alimentée en électricité, courant en altitude au dessus des rails R, comme représenté de manière schématique sur les figures 7 et 8. La modularité de la toiture 60 présente alors tout son intérêt.In a second step, it is considered that the car 1 leaves the above-mentioned maintenance station, rolling on the rails R, until reaching an intervention site along the railroad tracks R. At this site, intervention, the rails 2 stored on the platform 10 are for example to be unloaded and, to do this, the user will use the devices 30. However, the setting in motion of these devices 30 is, for reasons of safety, in particular related to the standard NF F 58-002 or the draft standard prEN 14033-1, incompatible with the presence of a catenary C supplied with electricity, running in altitude above the rails R, as shown schematically Figures 7 and 8. The modularity of the roof 60 is then of interest.
En effet, alors que le wagon 1 est stationné à proximité du site d'intervention, l'utilisateur commande, par le biais de l'armoire 92, le déploiement des quatre panneaux mobiles 74!, 742, 76i et 762 depuis leur position escamotée, représentée à la figure 1 , jusqu'à des positions déployées respectives, comme représenté dans des états intermédiaires successifs sur les figures 7 et 8.Indeed, while the car 1 is parked near the intervention site, the user controls, through the cabinet 92, the deployment of the four movable panels 74 ! , 74 2 , 76i and 76 2 from their retracted position, shown in Figure 1, to respective deployed positions, as shown in successive intermediate states in Figures 7 and 8.
Plus précisément, l'utilisateur commande d'abord le déploiement du panneau 74i par rapport au panneau fixe 72!, c'est-à-dire que, par l'intermédiaire de l'armoire de commande 92, il actionne le moteur 86 de manière à translater le chariot 82 et donc le panneau 74i vers l'avant, comme indiqué par la flèche Fi à la figure 7, jusqu'à ce que ce panneau atteigne sa position déployée représentée à la figure 7, dans laquelle le panneau recouvre la partie de plate-forme 10C. Dans sa position déployée, le panneau 74Ï est quasiment en totalité disposé en saillie vers l'avant du panneau 721 ; sans discontinuité entre eux, suivant la direction longitudinale de la plate-forme 10. Ensuite, de façon analogue, l'utilisateur commande le déploiement motorisé des panneaux 762 puis 742, de sorte qu'il lui reste à déployer le dernier des quatre panneaux, à savoir le panneau 76i . La figure 8 illustre le déploiement en cours de ce panneau 76i, sa translation vers l'arrière étant indiquée par la flèche F2. Le moteur d'entraînement de ce panneau 76i présente la particularité par rapport aux moteurs d'entraînement des trois autres panneaux mobiles, d'intégrer un limiteur d'intensité pour éviter que, lorsque le panneau 76i atteint sa position déployée, il ne s'emmanche violemment dans le panneau 742 déjà déployé et que ces deux panneaux ne se coincent ainsi l'un avec l'autre. Bien entendu, un autre ordre de déploiement des quatre panneaux mobiles que celui décrit juste ci-dessus est possible, dans la mesure où, in fine, les quatre panneaux sont déployés, avec le bord arrière du panneau 76i et le bord avant du panneau 742 accolés l'un à l'autre ou se chevauchant légèrement, sans toutefois être coincés l'un vis-à-vis de l'autre.More specifically, the user first controls the deployment of the panel 74i relative to the fixed panel 72 ! , that is to say that, via the control cabinet 92, it actuates the motor 86 so as to translate the carriage 82 and thus the panel 74i forward, as indicated by the arrow Fi in Figure 7, until the panel reaches its deployed position shown in Figure 7, wherein the panel covers the platform portion 10C. In its extended position, the panel 74 Ï is almost entirely disposed projecting toward the front of panel 72 1; without discontinuity between them, in the longitudinal direction of the platform 10. Then, similarly, the user controls the motorized deployment of the panels 76 2 and 74 2 , so that it remains to deploy the last of the four panels, namely the panel 76i. FIG. 8 illustrates the current deployment of this panel 76i, its translation towards the rear being indicated by the arrow F 2 . The driving motor of this panel 76i has the particularity with respect to the drive motors of the other three movable panels, to integrate a current limiter to prevent that, when the panel 76i reaches its deployed position, it is not sneaks into the panel 74 2 already deployed and that these two panels do not get together with each other. Of course, another order of deployment of the four movable panels than that described just above is possible, since, ultimately, the four panels are deployed, with the rear edge of the panel 76i and the front edge of the panel 74 2 joined to each other or overlapping slightly, but not wedged one vis-a-vis the other.
Une fois que les quatre panneaux mobiles 74i, 742, 76i et IQ2 sont dans leur position déployée, l'utilisateur en est averti par l'armoire de commande 92 qui reçoit des signaux correspondants de la part des détecteurs de fins de course 90 respectivement associés à ces quatre panneaux. Avantageusement, dans la mesure où l'armoire de commande 92 a également reçu de la part des détecteurs 90 des signaux représentatifs du fait que chacun des panneaux mobiles est dans sa position escamotée, cette armoire 92 commande, dès que l'un des quatre panneaux mobiles quitte sa position escamotée pour sa position déployée et tant que les panneaux mobiles ne sont pas tous les quatre dans leur position déployée, l'actionnement de moyens d'avertissement lumineux et/ou sonore à l'attention de l'utilisateur, tels qu'un gyrophare 94 et une sirène 96 (figure 1 ).Once the four movable panels 74i, 74 2 , 76i and IQ 2 are in their deployed position, the user is notified by the control cabinet 92 which receives corresponding signals from the end-of-travel detectors 90 respectively associated with these four panels. Advantageously, since the control cabinet 92 has also received from the detectors 90 representative signals that each of the movable panels is in its retracted position, this cabinet 92 controls, as soon as one of the four panels mobile leaves its retracted position for its deployed position and as the movable panels are not all four in their deployed position, the actuation of light warning means and / or sound to the attention of the user, such as a beacon 94 and a siren 96 (Figure 1).
Le wagon 1 est alors dans une configuration permettant à l'utilisateur d'utiliser en toute sécurité les dispositifs de chargement et déchargement 30, malgré la présence de la caténaire sous tension C puisque la toiture 60 recouvre alors en continu toute la plate-forme 10, en étant interposé entre les composants mobiles de ces dispositifs 30 et les rails 2 qui vont être déchargés à l'aide de ces dispositifs depuis la plate-forme 10. Les normes de sécurité précitées sont ainsi respectées, si bien que l'armoire 92 suspend la désactivation des dispositifs 30 qu'elle maintenait jusqu'alors, c'est-à-dire que ces dispositifs peuvent alors être utilisés, en étant commandé notamment à l'aide de leur pupitre 50.The wagon 1 is then in a configuration allowing the user to safely use the loading and unloading devices 30, despite the presence of the catenary under voltage C since the roof 60 then covers continuously the entire platform 10 , being interposed between the moving components of these devices 30 and the rails 2 which will be discharged using these devices from the platform 10. The aforementioned safety standards are thus met, so that the cabinet 92 suspends the deactivation of the devices 30 which it has maintained until now, that is to say that these devices can then be used, in particular being controlled by means of their console 50.
La figure 9 illustre d'ailleurs l'utilisation d'un des dispositifs 30 : le bras 40 de ce dispositif ne s'étend plus en longueur suivant la direction longitudinale de la plate-forme 10, comme sur les figures précédentes, mais s'étend perpendiculairement à cette direction longitudinale, de manière que le chariot 42 puisse, en fonction de sa position le long du bras 40, être disposé soit verticalement à l'aplomb de la face supérieure 18A du corps de plate-forme 18, soit à l'extérieur de la projection verticale de cette face 18A. On comprend ainsi que les rails 2 stockés sur la plate-forme 10 peuvent alors être soulevés par le palan 46, puis être déplacés par translation du chariot 42 jusqu'à l'extérieur de la plate-forme 10, latéralement à cette dernière. En pratique, le pivotement du bras 40 entre sa position à la figure 1 et sa position à la figure 9 est réalisé manuellement par l'utilisateur, en agissant directement sur le moyeu 36 qui est pourvu à cet effet de poignées 58. En outre, le moyeu 36 est avantageusement bloqué dans l'une et l'autre des deux positions privatées précitées à l'aide d'une broche d'arrêt 59 (figure 3) que l'utilisateur met en place pour verrouiller en position le bras 40. Divers aménagements optionnels et variantes du wagon 1 sont par ailleurs envisageables. A titre d'exemples :FIG. 9 also illustrates the use of one of the devices 30: the arm 40 of this device no longer extends in length along the longitudinal direction of the platform 10, as in the previous figures, but extends perpendicularly to this longitudinal direction, so that the carriage 42 may, depending on its position along the arm 40, be arranged either vertically above the upper face 18A of the platform body 18, or at the outside the vertical projection of this face 18A. We thus understand that the rails 2 stored on the platform 10 can then be lifted by the hoist 46, then be moved by translation of the carriage 42 to the outside of the platform 10, laterally to the latter. In practice, the pivoting of the arm 40 between its position in Figure 1 and its position in Figure 9 is performed manually by the user, acting directly on the hub 36 which is provided for this purpose handles 58. In addition, the hub 36 is advantageously locked in one and the other of the two aforementioned privatized positions by means of a stop pin 59 (FIG. 3) which the user puts in place to lock the arm 40 in position. Various optional arrangements and variants of the car 1 are also possible. As examples:
- les deux dispositifs de chargement et déchargement peuvent être synchronisés en ce qui concerne le déplacement de leur chariot 44, en particulier lorsque les rails à manutentionner 2 présentent une longueur supérieure à la moitié de celle de la plate-forme 10 ;the two loading and unloading devices can be synchronized with respect to the displacement of their carriage 44, in particular when the rails to be handled 2 have a length greater than half that of the platform 10;
- de même, si les rails à manutentionner 2 sont plus longs que la plate-forme 10, deux voire davantage de wagons 1 sont associés "en série" et asservis conjointement ;- Similarly, if the rails to handle 2 are longer than the platform 10, two or more cars 1 are associated "in series" and enslaved jointly;
- en cas de disfonctionnement du moteur 86 et des moteurs d'entraînement analogues ou, plus généralement, en cas de coincement des panneaux mobiles 74i, 742, 76i et 762, les moteurs précités intègrent un système de débrayage manuel que l'utilisateur sollicite pour, le cas échéant, entraîner manuellement un ou plusieurs des panneaux mobiles entre leurs positions escamotée et déployée ; - à des fins de sécurité, le wagon 1 est équipé de plusieurs boutons d'arrêt d'urgence ;- In case of malfunction of the motor 86 and similar drive motors or, more generally, in case of jamming of the movable panels 74i, 74 2 , 76i and 762, the aforementioned motors include a manual release system that the user requests to, if necessary, manually drive one or more of the movable panels between their retracted and deployed positions; - for safety purposes, wagon 1 is equipped with several emergency stop buttons;
- l'alimentation électrique des différents moteurs embarqués sur le wagon 1 est assurée soit par une source extérieure si celle-ci est disponible, soit par un groupe électrogène également embarqué sur le wagon 1 , notamment agencé dans le châssis 12, un tel groupe électrogène étant par exemple visé par la référence 98 à la figure 1 , et/ou- The power supply of the various engines on board the car 1 is provided either by an external source if it is available, or by a generator also embedded on the car 1, in particular arranged in the frame 12, such a generator being for example referred to by reference 98 in FIG. 1, and / or
- divers éléments d'équipement conventionnels du wagon 1 peuvent être rapportés sur celui-ci, du moment qu'ils ne gênent pas le déploiement des panneaux mobiles ; en particulier, des lampes d'éclairage, visées par les références 99, peuvent être agencées au niveau du châssis 12 ainsi que le long du côté inférieur de la poutre 68. - Various conventional equipment of car 1 may be reported on it, as long as it does not interfere with the deployment of movable panels; in particular, lighting lamps, referred to by the references 99, may be arranged at the frame 12 as well as along the lower side of the beam 68.
