Description

La présente invention concerne le domaine de l'installation d'un équipement, en particulier, un équipement ferroviaire (rail, coeur d'aiguillage, etc.) lors du renouvellement d'une voie de chemin de fer.The present invention relates to the field of installation of equipment, in particular, railway equipment (rail, routing core, etc.) during the renewal of a railway track.

Une voie de chemin de fer, appelée également voie ferrée, s'étend longitudinalement et comprend deux rails longitudinaux reposant sur des traverses transversales. Chaque rail longitudinal est formé d'une pluralité de tronçons qui sont soudés ensemble à leurs extrémités et fixés aux traverses.A railroad track, also known as a railway line, extends longitudinally and comprises two longitudinal rails resting on transverse crosspieces. Each longitudinal rail is formed of a plurality of sections which are welded together at their ends and fixed to the sleepers.

Du fait de l'usure induite par la circulation de véhicules ferroviaires sur la voie ferrée, il est nécessaire de remplacer de manière périodique les rails longitudinaux usagés par des rails longitudinaux neufs.Because of the wear induced by the circulation of railway vehicles on the railway, it is necessary to periodically replace the longitudinal rails used by new longitudinal rails.

En référence à la demande de brevet FR 2847917A1 , il est connu d'utiliser un train ferroviaire (train-travaux) pour stocker les rails longitudinaux neufs et les installer dans une zone de maintenance. Lors de son utilisation, un tel train ferroviaire présente l'inconvénient d'occuper une voie ferrée adjacente à la voie ferrée à renouveler. Cela est pénalisant lorsque deux gares ne sont reliées que par deux voies ferrées adjacentes, toute circulation entre les gares est alors interdite, ce qui présente une gêne importante ainsi qu'un manque à gagner pour les exploitants du réseau ferré. Du fait de ces inconvénients, les opérations de renouvellement d'une voie ferrée ne sont réalisées qu'au cours de la nuit, ce qui allonge de manière importante la durée des opérations de renouvellement.With reference to the patent application FR 2847917A1 it is known to use a rail train (train-work) to store the new longitudinal rails and install them in a maintenance area. In use, such a railway train has the disadvantage of occupying a railway adjacent to the railway to be renewed. This is penalizing when two stations are connected only by two adjacent railroads, any traffic between the stations is then prohibited, which presents a significant inconvenience and a shortfall for the operators of the rail network. Because of these disadvantages, the renewal operations of a railway are only carried out during the night, which significantly increases the duration of the renewal operations.

On connaît par ailleurs, par la demande de brevet FR2394641 A1 , un véhicule ferroviaire comprenant une poutre de pose de tronçon supportée par un bras de levage. Un tel véhicule ferroviaire possède un encombrement important ainsi qu'une masse élevée, ce qui empêche une manipulation et un transport aisés d'une telle poutre et d'un tel bras.It is also known, by the patent application FR2394641 A1 , a railway vehicle comprising a section laying beam supported by a lifting arm. Such a rail vehicle has a large footprint and a high mass, which prevents easy handling and transport of such a beam and such an arm.

L'invention a donc pour but de remédier à ces inconvénients en proposant une poutre de support d'un équipement, en particulier un rail ferroviaire, de conception nouvelle afin de faciliter sa manipulation et son transport tout en garantissant un support fiable de l'équipement même si ce dernier possède une répartition massique hétérogène selon sa longueur.The invention therefore aims to remedy these drawbacks by proposing a support beam of a piece of equipment, in particular a railway rail, of new design in order to facilitate its handling and its transport while guaranteeing a reliable support of the equipment. even if the latter has a heterogeneous mass distribution according to its length.

L'invention est née dans le domaine ferroviaire mais elle peut s'appliquer à tout domaine nécessitant le transport d'un équipement, de préférence, un équipement longitudinal dont la masse est élevée.The invention was born in the railway field but it can be applied to any field requiring the transport of equipment, preferably a longitudinal equipment whose mass is high.

PRESENTATION GENERALE DE L'INVENTIONGENERAL PRESENTATION OF THE INVENTION

A cet effet, l'invention concerne une poutre structurale adaptée pour supporter un équipement, en particulier un rail ferroviaire, ladite poutre comportant un corps longitudinal comprenant une première extrémité de connexion et une deuxième extrémité de connexion adaptées pour se connecter à des moyens de déplacement, et une pluralité d'éléments de liaison, répartis le long dudit corps longitudinal, qui sont adaptés pour être reliés audit équipement afin de le suspendre audit corps longitudinal.For this purpose, the invention relates to a structural beam adapted to support equipment, in particular a railway rail, said beam comprising a longitudinal body comprising a first connection end and a second connection end adapted to connect to moving means. and a plurality of connecting elements, distributed along said longitudinal body, which are adapted to be connected to said equipment in order to suspend it to said longitudinal body.

La poutre structurale peut être portée par ses extrémités, ce qui optimise la longueur du corps longitudinal apte à répartir et à faire transiter les efforts reçus par les éléments de liaison. Ainsi, pour supporter un même équipement, une poutre de support selon l'invention peut posséder une longueur limitée et un encombrement réduit par comparaison à une poutre de support utilisée dans l'art antérieur sur des trains-travaux et maintenue en son centre par une grue de levage ou analogue.The structural beam can be carried by its ends, which optimizes the length of the longitudinal body capable of distributing and passing the forces received by the connecting elements. Thus, to support the same equipment, a support beam according to the invention can have a limited length and a small footprint compared to a support beam used in the prior art on trains-work and maintained in its center by a lifting crane or the like.

De préférence, le corps longitudinal est modulaire de manière à permettre son stockage avec un faible encombrement. Ainsi, la poutre de support peut être logée dans un véhicule routier de faibles dimensions, ce qui évite de recourir à un véhicule ferroviaire comme dans l'art antérieur.Preferably, the longitudinal body is modular so as to allow storage with a small footprint. Thus, the support beam can be housed in a road vehicle of small dimensions, which avoids resorting to a rail vehicle as in the prior art.

De préférence encore, le corps longitudinal comporte une pluralité de modules indépendants reliés les uns aux autres de manière amovible. Ainsi, les modules peuvent être avantageusement empilés pour limiter de manière importante leur encombrement.More preferably, the longitudinal body comprises a plurality of independent modules removably connected to each other. Thus, modules can advantageously stacked to significantly reduce their size.

De manière préférée, le corps longitudinal est réglable en longueur afin de s'adapter aux dimensions de l'équipement à supporter et aux contraintes liées au chemin de déplacement de la poutre de support. En outre, un corps réglable en longueur permet de s'adapter à des accès étroits.Preferably, the longitudinal body is adjustable in length in order to adapt to the dimensions of the equipment to be supported and the constraints related to the path of movement of the support beam. In addition, a body adjustable in length allows to adapt to narrow access.

Le corps longitudinal comporte avantageusement une pluralité de modules articulés les uns aux autres, ce qui facilite le réglage de la longueur de la poutre ainsi que son stockage. De préférence, le corps longitudinal est configuré pour se déplier dans un plan horizontal, ce qui permet avantageusement un dépliage dans un tunnel.The longitudinal body advantageously comprises a plurality of modules articulated to each other, which facilitates the adjustment of the length of the beam and its storage. Preferably, the longitudinal body is configured to unfold in a horizontal plane, which advantageously allows unfolding in a tunnel.

Selon un aspect de l'invention, au moins une partie du corps longitudinal est télescopique afin de permettre un dépliage rapide en position d'utilisation tout en ayant un encombrement limité en position de stockage.According to one aspect of the invention, at least a portion of the longitudinal body is telescopic to allow rapid unfolding in the use position while having a limited space in the storage position.

Selon un autre aspect de l'invention au moins une partie du corps longitudinal possède une structure en ciseaux afin de permettre un dépliage rapide en position d'utilisation tout en possédant un encombrement limité en position de stockage.According to another aspect of the invention at least a portion of the longitudinal body has a scissor structure to allow rapid unfolding in the use position while having a limited space in the storage position.

De manière préférée la poutre de support est dépourvue, au niveau de sa partie centrale, de moyens de connexion à une grue de levage ou analogue, ce qui limite sa masse.Preferably the support beam is devoid, at its central portion, connecting means to a hoisting crane or the like, which limits its mass.

De préférence, le corps longitudinal est en acier ou en matériaux composites afin de posséder une masse limitée et une résistance mécanique importante, en particulier, aux efforts de flambage. De manière avantageuse, le corps longitudinal est configuré pour supporter une masse élevée, dans cet exemple, de l'ordre de 8 tonnes.Preferably, the longitudinal body is made of steel or composite materials in order to have a limited mass and a high mechanical strength, in particular, buckling forces. Advantageously, the longitudinal body is configured to support a high mass, in this example, of the order of 8 tons.

De manière préférée, la longueur du corps longitudinal est de l'ordre de 30 mètres afin de supporter de manière stable un équipement de masse ou de longueur élevée.Preferably, the length of the longitudinal body is of the order of 30 meters in order to stably support equipment of mass or long length.

La poutre de support comporte, de manière avantageuse, des moyens de stabilisation autonome adaptés pour être en appui sur un sol, de préférence, une pluralité de jambages. Ainsi, la poutre peut être montée/dépliée au-dessus du sol sans pénibilité par les opérateurs. De préférence, les moyens de stabilisation autonome sont intégrés à chaque module de la poutre de support.The support beam advantageously comprises autonomous stabilization means adapted to bear on a floor, preferably a plurality of jambs. Thus, the beam can be mounted / unfolded above the ground without difficulty by the operators. Preferably, the autonomous stabilization means are integrated in each module of the support beam.

L'invention concerne également un ensemble d'une poutre telle que présentée précédemment et d'un premier convoyeur mobile et d'un deuxième convoyeur mobile reliés respectivement à la première extrémité de connexion et à la deuxième extrémité de connexion de la poutre afin de la déplacer. Un tel ensemble est avantageux pour déplacer un équipement de manière rapide et fiable sans recourir à un train-travaux selon l'art antérieur.The invention also relates to an assembly of a beam as presented above and a first mobile conveyor and a second movable conveyor respectively connected to the first connection end and the second connection end of the beam to the move. Such an assembly is advantageous for moving a piece of equipment quickly and reliably without resorting to a work train according to the prior art.

DESCRIPTION D'UN OU PLUSIEURS MODES DE REALISATION ET DE MISE EN OEUVREDESCRIPTION OF ONE OR MORE MODES OF REALIZATION AND IMPLEMENTATION

La poutre de support selon l'invention va être présentée pour le support d'un équipement ferroviaire longitudinal mais il va de soi que l'invention est adaptée pour supporter tout type d'équipement (un garde-corps, une rampe, une balustrade, un longeron, une poutre, etc.) pour une utilisation dans tout type d'industrie.The support beam according to the invention will be presented for the support of a longitudinal rail equipment but it goes without saying that the invention is adapted to support any type of equipment (a railing, a ramp, a railing, a spar, a beam, etc.) for use in any type of industry.

Une telle poutre de support permet en particulier la manutention de tout équipement, même non équilibré massiquement, c'est-à-dire, dont la masse est répartie de manière non homogène selon sa longueur. Grâce à une telle poutre de support, les contraintes mécaniques sont réparties de manière uniforme, sans risque de déformation de l'équipement.Such a support beam in particular allows the handling of any equipment, even unbalanced mass, that is to say, whose mass is distributed non-homogeneously along its length. Thanks to such a support beam, the mechanical stresses are distributed in a uniform manner, without risk of deformation of the equipment.

En référence à la figure 1, il est représenté de manière schématique une poutre de support 1 selon l'invention transportant un rail ferroviaire longitudinal 2 entre un lieu de stockage de rails ferroviaires et un lieu de maintenance.With reference to the figure 1 , it is shown schematically a support beam 1 according to the invention carrying a longitudinal rail rail 2 between a railway rail storage location and a maintenance place.

La poutre de support 1 est dite structurale car elle permet de faire transiter des efforts mécaniques importants et, en particulier, supporter un équipement de masse élevée, de l'ordre de 8 tonnesThe support beam 1 is said to be structural because it makes it possible to pass significant mechanical forces and, in particular, support a high mass equipment, of the order of 8 tons

Dans cet exemple, la poutre de support 1 possède une hauteur verticale plus importante que son épaisseur latérale afin de présenter une résistance importante au flambage tout en limitant son encombrement.In this example, the support beam 1 has a vertical height greater than its lateral thickness in order to have a high resistance to buckling while limiting its size.

En référence à la figure 1, la poutre de support 1 comporte un corps longitudinal 10 ayant une longueur supérieure à 30 mètres afin de supporter des équipements de grande longueur tels que des rails longitudinaux.With reference to the figure 1 , support beam 1 comprises a longitudinal body 10 having a length greater than 30 meters in order to support equipment of great length such as longitudinal rails.

La poutre de support 1 comporte une première extrémité de connexion 11 et une deuxième extrémité de connexion 12 adaptées pour se connecter à des moyens de déplacement, en particulier, des convoyeurs mobiles 31, 32 tels que des automates routiers ou ferroviaires. De manière préférée, chaque extrémité de connexion 11, 12 possède une forme sensiblement sphérique afin de former une liaison rotule avec les convoyeurs mobiles 31, 32 de manière à limiter toute contrainte lié au débattement de la poutre 1 lors de son déplacement. Ainsi, de manière avantageuse, la poutre de support 1 est équilibrée verticalement de manière automatique même si les convoyeurs 31, 32 sont inclinés du fait d'un nivellement du sol. Il va de soi que d'autres types d'extrémités de connexion 11, 12 pourraient également convenir.The support beam 1 comprises a first connection end 11 and a second connection end 12 adapted to connect to moving means, in particular mobile conveyors 31, 32 such as road or rail automata. Preferably, each connection end 11, 12 has a substantially spherical shape to form a ball joint with the movable conveyors 31, 32 so as to limit any constraint related to the displacement of the beam 1 during its movement. Thus, advantageously, the support beam 1 is vertically balanced automatically even if the conveyors 31, 32 are inclined due to a leveling of the ground. It goes without saying that other types of connection ends 11, 12 could also be suitable.

De manière avantageuse, une extrémité de connexion comportant une chape en forme de U montée sur un pivot libre ainsi qu'une liaison articulée permettent de former une liaison rotule de manière pratique afin de limiter le débattement de la poutre structurale 1 comme cela sera présenté par la suite. Une extrémité de connexion sphérique est particulièrement avantageuse étant donné qu'elle possède un coût de revient limité.Advantageously, a connection end comprising a U-shaped yoke mounted on a free pivot as well as an articulated connection makes it possible to form a ball joint in a practical manner in order to limit the deflection of the structural beam 1 as will be presented by the following. A spherical connection end is particularly advantageous since it has a limited cost.

De telles extrémités de connexion 11, 12 permettent de supporter la poutre de support 1 par ses extrémités afin d'optimiser la répartition des efforts induits par l'équipement 2 sur toute la longueur du corps longitudinal 10. Ainsi, la poutre de support 1 peut supporter un équipement 2 de masse élevée sans risque de rupture tout en possédant une longueur réduite.Such connection ends 11, 12 make it possible to support the support beam 1 at its ends in order to optimize the distribution of the forces induced by the equipment 2 over the entire length of the longitudinal body 10. Thus, the support beam 1 can support a high mass equipment 2 without risk of rupture while having a reduced length.

De manière préférée, chaque partie d'extrémité du corps longitudinal possède une section décroissante du centre du corps longitudinal 10 vers son extrémité de connexion 11, 12, comme illustré à la figure 1, afin de limiter les débattements.Preferably, each end portion of the longitudinal body has a decreasing section of the center of the longitudinal body 10 towards its connecting end 11, 12, as illustrated in FIG. figure 1 , in order to limit the deflections.

Le corps longitudinal 10 de la poutre de support 1 est en acier et ou en matériaux composites afin de posséder une résistance importante, en particulier au flambage, pour une masse réduite. De préférence, le corps longitudinal 10 de la poutre de support 1 est creux. De manière avantageuse, le corps longitudinal 10 comporte une enveloppe de protection afin d'éviter tout risque de blessure d'un opérateur lors de la manutention de la poutre de support 1.The longitudinal body 10 of the support beam 1 is made of steel and or composite materials in order to have a high resistance, in particular buckling, for a reduced mass. Preferably, the longitudinal body 10 of the support beam 1 is hollow. Advantageously, the longitudinal body 10 comprises a protective envelope in order to avoid any risk of injury to an operator during the handling of the support beam 1.

En référence à la figure 1, la poutre de support 1 comporte une pluralité d'éléments de liaison 13, répartis le long dudit corps longitudinal 10, qui sont adaptés pour être reliés à l'équipement 2 afin de le suspendre audit corps longitudinal 10. Autrement dit, la pluralité d'éléments de liaison 13 forme des moyens de mouflage, c'est-à-dire, des moyens de levage d'une charge selon plusieurs zones écartées les unes des autres.With reference to the figure 1 , the support beam 1 comprises a plurality of connecting elements 13, distributed along said longitudinal body 10, which are adapted to be connected to the equipment 2 in order to suspend it to said longitudinal body 10. In other words, the plurality of connecting elements 13 form means of hauling, that is to say, means for lifting a load in several zones spaced from each other.

De préférence, au moins une pluralité d'éléments de liaison 13 sont mobiles selon la longueur du corps longitudinal 10 de manière à pouvoir placer les éléments de liaison 13 de manière adaptable en fonction de la forme et de la répartition massique de chaque équipement à porter. De manière préférée, le déplacement des éléments de liaison 13 est motorisé et, de préférence, piloté par un opérateur.Preferably, at least a plurality of connecting elements 13 are movable along the length of the longitudinal body 10 so as to be able to place the connecting elements 13 adaptably according to the shape and the mass distribution of each equipment to be worn. . Preferably, the displacement of the connecting elements 13 is motorized and, preferably, controlled by an operator.

Dans cet exemple de réalisation, chaque élément de liaison 13 se présente sous la forme d'une boucle flexible adaptée pour être passé sous l'équipement afin de le soulever. Il va de soi que les éléments de liaison 13 pourraient se présenter sous une forme différente.In this embodiment, each connecting element 13 is in the form of a flexible loop adapted to be passed under the equipment to lift it. It goes without saying that the connecting elements 13 could be in a different form.

De tels éléments de liaison 13 permettent de supporter des équipements ferroviaires tels que des demi-aiguillages, des coeurs d'aiguillage et, ce, indépendamment de leur masse et/ou de la position de leur centre de gravité. En outre, lors du support, la forme, les dimensions et l'état de surface de l'équipement ne sont pas affectés, ce qui est très avantageux.Such connecting elements 13 make it possible to support railway equipment such as half-switches, switching cores and, independently of their mass and / or the position of their center of gravity. In addition, during the support, the shape, the dimensions and the surface condition of the equipment are not affected, which is very advantageous.

Lors de son utilisation, la poutre de support 10 possède une longueur importante pour favoriser un support équilibré et stable d'un équipement 2. A l'inverse, lors de son stockage, la poutre de support 10 possède une longueur réduite afin de limiter son encombrement et faciliter son transport, en particulier, dans un camion de transport routier, de préférence, un camion semi-remorque de catégorie 1.In use, the support beam 10 has a long length to promote a balanced and stable support of a device 2. On the other hand, during its storage, the support beam 10 has a reduced length in order to limit its congestion and facilitate its transport, in particular, in a road transport truck, preferably a category 1 semi-trailer truck.

De manière préférée, en référence aux figures 2 et 3, le corps longitudinal 10 de la poutre de support 1 comprend une pluralité de modules structuraux 100 reliés les uns aux autres de manière amovible. Dans cet exemple, le corps longitudinal 10 de la poutre de support 1 comporte 7 modules mais il va de soi que le nombre de modules 100 pourrait être différent.Preferably, with reference to Figures 2 and 3 , the longitudinal body 10 of the support beam 1 comprises a plurality of structural modules 100 releasably connected to each other. In this example, the longitudinal body 10 of the support beam 1 has 7 modules but it goes without saying that the number of modules 100 could be different.

De manière avantageuse, la longueur d'un module structural 100 est inférieure à 20 m afin de permettre le stockage d'un tel module structural dans un camion semi-remorque de catégorie 1.Advantageously, the length of a structural module 100 is less than 20 m in order to allow the storage of such a structural module in a category 1 semi-trailer truck.

De préférence, les modules structuraux 100 possèdent des longueurs différentes de manière à permettre l'assemblage d'une poutre de support 1 de longueur désirée.Preferably, the structural modules 100 have different lengths so as to allow the assembly of a support beam 1 of desired length.

Comme illustré à la figure 3, chaque module 100 comporte à au moins une de ses extrémités longitudinales des moyens de connexion avec un autre module 100 de la poutre de support 10. Les moyens de connexion permettent avantageusement de centrer deux modules 100 consécutifs. Parmi les moyens de connexion, on distingue des moyens de connexion mâle 101 et des moyens de connexion femelle 102 adaptés pour coopérer ensemble et permettre le transfert des efforts structuraux d'un module 100 à un autre.As illustrated in figure 3 each module 100 comprises at least one of its longitudinal ends connecting means with another module 100 of the support beam 10. The connection means advantageously allow to center two consecutive modules 100. Among the connection means, there are male connection means 101 and female connection means 102 adapted to cooperate together and allow the transfer of structural forces from one module 100 to another.

A titre d'exemple, en référence à la figure 3, chaque moyen de connexion mâle 101 se présente sous la forme d'une languette longitudinale tandis que chaque moyen de connexion femelle 102 se présente sous la forme d'un logement longitudinal (non visible sur les figures) dont la forme est complémentaire à la languette. Ainsi, lors de la connexion de deux modules structuraux 100 ensemble, ces derniers sont alignés de manière précise. De préférence encore, chaque module 100 comprend des moyens de verrouillage de l'assemblage de deux modules 100 consécutifs assemblés ensemble. Dans cet exemple, en référence à la figure 3, chaque module 100 comprend des ouvertures traversantes 103 au niveau de ses moyens de connexion 101, 102 de manière à permettre le verrouillage de deux modules assemblés 100 par brochage ou goupillage. Il va de soi que les moyens de verrouillage pourraient être différents. En particulier, les moyens de verrouillage pourraient être intégrés aux moyens de connexion 101, 102.For example, with reference to the figure 3 each male connection means 101 is in the form of a longitudinal tongue while each female connection means 102 is in the form of a longitudinal housing (not visible in the figures) whose shape is complementary to the tongue . So, during the connection of two structural modules 100 together, the latter are aligned accurately. More preferably, each module 100 comprises means for locking the assembly of two consecutive modules 100 assembled together. In this example, with reference to the figure 3 , each module 100 comprises through openings 103 at its connection means 101, 102 so as to allow the locking of two assembled modules 100 by pinning or pinning. It goes without saying that the locking means could be different. In particular, the locking means could be integrated with the connection means 101, 102.

La poutre de support 1 est, dans cet exemple, symétrique. En outre, la partie centrale de la poutre de support 1 possède une section centrale sensiblement constante, ce qui est avantageux pour supporter un équipement 2 de manière équilibrée. En outre, le nombre de modules structuraux 100 de la poutre de support 1 peut être adapté en fonction de la longueur de l'équipement 2 à soulever.The support beam 1 is, in this example, symmetrical. In addition, the central portion of the support beam 1 has a substantially constant central section, which is advantageous for supporting equipment 2 in a balanced manner. In addition, the number of structural modules 100 of the support beam 1 can be adapted according to the length of the equipment 2 to be lifted.

De manière préférée, le corps longitudinal 10 de la poutre de support 1 est assemblé en hauteur par rapport au sol. Le corps longitudinal 10 est maintenu en hauteur par rapport au sol par des moyens de stabilisation autonome (non représentés) adaptés pour être en appui sur le sol.Preferably, the longitudinal body 10 of the support beam 1 is assembled in height relative to the ground. The longitudinal body 10 is maintained in height relative to the ground by autonomous stabilization means (not shown) adapted to bear on the ground.

Les moyens de stabilisation autonome se présentent de préférence sous la forme d'un jambage afin de faciliter le positionnement et le stationnement d'un module 100 lors de son assemblage. De manière préférée, chaque module 100 comporte un jambage escamotable. De préférence encore, chaque jambage est équipé d'un actionneur motorisé pour faciliter son pliage/dépliage. De préférence toujours, chaque jambage comporte un sabot d'appui qui est articulé afin de s'adapter au relief du sol sur lequel est en appui le jambage.The autonomous stabilization means are preferably in the form of a jamb to facilitate the positioning and parking of a module 100 during its assembly. Preferably, each module 100 comprises a retractable jamb. More preferably, each leg is equipped with a motorized actuator to facilitate its folding / unfolding. Preferably still, each leg comprises a support shoe which is articulated to adapt to the relief of the ground on which the jamb is supported.

Selon une autre forme de réalisation, en référence aux figures 4 et 5, le corps longitudinal 10 de la poutre de support 1 comprend une pluralité de modules structuraux 200 adaptés pour s'emboîter les uns dans les autres afin de former une poutre télescopique. Dans cet exemple, le corps longitudinal 10 de la poutre de support 1 comporte 3 modules 200 mais il va de soi que le nombre de modules 200 pourrait être différent. De manière avantageuse, la longueur d'un module structural 200 est inférieure à 15 m, de préférence 10 m, afin de permettre le stockage d'un module 200 dans un camion semi-remorque de catégorie 1.According to another embodiment, with reference to Figures 4 and 5 , the longitudinal body 10 of the support beam 1 comprises a plurality of structural modules 200 adapted to fit into each other to form a telescopic beam. In this example, the longitudinal body 10 of the support beam 1 has 3 modules 200 but it goes without saying that the number of modules 200 could be different. Advantageously, the length of a structural module 200 is less than 15 m, preferably 10 m, in order to allow the storage of a module 200 in a category 1 semi-trailer truck.

Dans cet exemple, les modules 200 possèdent des sections différentes de manière à permettre un emboîtement les uns dans les autres.In this example, the modules 200 have different sections so as to allow interlocking into each other.

De manière avantageuse, la longueur d'une telle poutre télescopique peut être rapidement réglée entre sa position d'utilisation (Figure 4) et sa position de stockage (Figure 5). En outre, la longueur de la poutre de support 1 peut être adaptée en fonction de la longueur de l'équipement 2 à soulever.Advantageously, the length of such a telescopic beam can be quickly adjusted between its position of use ( Figure 4 ) and its storage position ( Figure 5 ). In addition, the length of the support beam 1 can be adapted according to the length of the equipment 2 to be lifted.

Selon une autre forme de réalisation, en référence aux figures 6 à 11, le corps longitudinal 10 de la poutre de support 1 comprend une pluralité de modules structuraux 300 adaptés pour se plier les uns sur les autres comme illustré plus particulièrement à la figure 10. Dans cet exemple, le corps longitudinal 10 de la poutre de support 1 comporte 3 modules 300 mais il va de soi que le nombre de modules 300 pourrait être différent. De manière avantageuse, la longueur d'un module structural 300 est inférieur à 15 m afin d'être stockée dans un camion semi-remorque de catégorie 1.According to another embodiment, with reference to Figures 6 to 11 , the longitudinal body 10 of the support beam 1 comprises a plurality of structural modules 300 adapted to bend on each other as illustrated more particularly in FIG. figure 10 . In this example, the longitudinal body 10 of the support beam 1 comprises 3 modules 300 but it goes without saying that the number of modules 300 could be different. Advantageously, the length of a structural module 300 is less than 15 m in order to be stored in a category 1 semi-trailer truck.

Comme illustré à la figure 9, deux modules 300 consécutifs sont reliés à leurs extrémités longitudinales par des moyens d'articulation 301 avec un autre module 300 de la poutre de support 10. Dans cet exemple, les moyens d'articulation 301 sont configurés pour autoriser une rotation selon une direction orthogonale à la direction longitudinale selon laquelle s'étend la poutre de support 1 en position d'utilisation. De préférence, les moyens d'articulation 301 sont configurés pour autoriser une rotation selon une direction verticale de manière à permettre un pliage de la poutre de support 1 dans un plan horizontal. Cela est particulièrement avantageux pour plier la poutre 1 lorsque l'espace vertical est limité, par exemple, pour un pliage dans un tunnel.As illustrated in figure 9 , two consecutive modules 300 are connected at their longitudinal ends by hinge means 301 with another module 300 of the support beam 10. In this example, the hinge means 301 are configured to allow rotation in an orthogonal direction in the longitudinal direction in which the support beam 1 extends in the position of use. Preferably, the hinge means 301 are configured to allow rotation in a vertical direction so as to allow folding of the support beam 1 in a horizontal plane. This is particularly advantageous for folding the beam 1 when the vertical space is limited, for example, for folding in a tunnel.

Dans cet exemple, les moyens d'articulation 301 se présentent sous la forme d'une charnière mais il va de soi que d'autres moyens d'articulation pourraient convenir, par exemple, une tige, une lame flexible, etc. De préférence, la poutre de support 1 comporte des moyens motorisés de dépliage, en particulier, des vérins.In this example, the hinge means 301 are in the form of a hinge but it goes without saying that other articulation means could be suitable, for example example, a rod, a flexible blade, etc. Preferably, the support beam 1 comprises motorized unfolding means, in particular, cylinders.

De manière avantageuse, la hauteur perdue, c'est-à-dire, la distance verticale séparant le (ou les) point(s) d'accrochage(s) de la charge et les extrémités de connexion, est faible, ce qui autorise des amplitudes importantes selon les 3 axes tout en respectant, par exemple, le gabarit d'une voie ferroviaire.Advantageously, the lost height, that is to say, the vertical distance separating the point (s) of attachment (s) from the load and the connection ends, is low, which allows large amplitudes according to the 3 axes while respecting, for example, the gauge of a railway track.

De manière avantageuse, la longueur d'une telle poutre de support 1 pliable peut être rapidement réglée entre une position d'utilisation de longueur maximale (Figures 6 et 7), une position d'utilisation de longueur intermédiaire (Figures 8 et 9) et une position de stockage (Figures 10 et 11). Ainsi, la longueur de la poutre de support 1 peut être adaptée en fonction de la longueur de l'équipement 2 à soulever.Advantageously, the length of such a foldable support beam 1 can be quickly adjusted between a position of use of maximum length ( Figures 6 and 7 ), an intermediate length position of use ( Figures 8 and 9 ) and a storage position ( Figures 10 and 11 ). Thus, the length of the support beam 1 can be adapted according to the length of the equipment 2 to be lifted.

Selon une autre forme de réalisation, en référence aux figures 12 et 13, le corps longitudinal 10 de la poutre de support 1 comporte une structure à ciseaux 400 de manière à se plier/déplier de manière rapide et aisée. Une telle structure à ciseaux 400 est connue en soi de l'homme du métier et ne sera pas présentée plus en détails.According to another embodiment, with reference to Figures 12 and 13 , the longitudinal body 10 of the support beam 1 comprises a scissor structure 400 so as to fold / unfold quickly and easily. Such a scissors structure 400 is known per se to those skilled in the art and will not be presented in more detail.

Le corps longitudinal 10 comporte des tronçons d'extrémités 401 configurés pour reprendre les efforts de manière répartie et homogène. De préférence, chaque tronçon d'extrémité 401 possède une forme triangulaire dont un bord est relié à la structure à ciseaux 400 et dont le sommet opposé audit bord comporte une extrémité de connexion 11, 12 comme illustré aux figures 12 et 13.The longitudinal body 10 comprises end sections 401 configured to take the forces in a distributed and homogeneous manner. Preferably, each end section 401 has a triangular shape whose edge is connected to the scissors structure 400 and whose apex opposite said edge has a connecting end 11, 12 as illustrated in FIGS. Figures 12 and 13 .

De manière avantageuse, la longueur d'une telle poutre de support 1 télescopique peut être rapidement réglée entre sa position d'utilisation (Figure 12) et sa position de stockage (Figure 13). En outre, la longueur de la poutre de support 1 peut être adaptée en fonction de la longueur de l'équipement 2 à soulever.Advantageously, the length of such a telescopic support beam 1 can be quickly adjusted between its position of use ( Figure 12 ) and its storage position ( Figure 13 ). In addition, the length of the support beam 1 can be adapted according to the length of the equipment 2 to be lifted.

En pratique, pour transporter un rail ferroviaire depuis une zone de stockage vers une zone de maintenance, les opérateurs réalisent tout d'abord une étape de déchargement d'un camion routier dans lequel est stockée la poutre de support 1. Ensuite, cette dernière est assemblée ou dépliée afin de posséder une longueur importante apte à supporter un rail ferroviaire de masse élevée. De préférence, la poutre de support 1 est maintenue en hauteur au-dessus du sol grâce à ses jambages.In practice, to transport a railway rail from a storage area to a maintenance area, the operators first perform a unloading step of a road truck in which is stored the support beam 1. Then, the latter is assembled or unfolded to have a significant length able to support a rail of high mass. Preferably, the support beam 1 is maintained in height above the ground thanks to its jambs.

Des convoyeurs mobiles 31, 32 se connectent ensuite aux extrémités de connexion 11, 12 de la poutre de support 1 afin de la soulever au-dessus du sol par ses extrémités afin de maximiser la longueur de poutre de support 1 apte à faire transiter des efforts.Movable conveyors 31, 32 then connect to the connection ends 11, 12 of the support beam 1 in order to raise it above the ground by its ends in order to maximize the length of the support beam 1 capable of transmitting forces .

Les éléments de liaison 13 de la poutre de support 1 sont placés autour du rail ferroviaire 2 reposant sur le sol. Dans cet exemple, les éléments de liaison 13 sont répartis à égale distance les uns des autres selon la longueur de la poutre de support 1 étant donné que cette dernière possède une répartition massique homogène selon sa longueur. De manière préférée, les éléments de liaison 13 sont déplacés de manière à suspendre l'équipement 2 à la poutre de support 1. En pratique, le rail ferroviaire 2 s'étend à moins de 200 cm selon la direction verticale de la poutre de support 1 lors de son déplacement afin de limiter tout basculement.The connecting elements 13 of the support beam 1 are placed around the rail rail 2 resting on the ground. In this example, the connecting elements 13 are distributed equidistant from each other along the length of the support beam 1 since the latter has a uniform mass distribution along its length. Preferably, the connecting elements 13 are moved so as to suspend the equipment 2 to the support beam 1. In practice, the rail 2 extends less than 200 cm in the vertical direction of the support beam 1 when moving to limit any tipping.

Les convoyeurs mobiles 31, 32 sont ensuite déplacés sur le sol puis sur la voie ferroviaire pour atteindre la zone de maintenance. Les extrémités de connexion 11, 12 sont avantageuses pour absorber les oscillations de la poutre de support 1 lors de son déplacement par les convoyeurs mobiles 31, 32. Pour libérer le rail ferroviaire 2, les éléments de liaison 13 sont descendus afin de reposer le rail ferroviaire 2 sur le sol qui peut ensuite être monté sur la voie ferroviaire.The mobile conveyors 31, 32 are then moved on the ground and then on the rail to reach the maintenance area. The connection ends 11, 12 are advantageous for absorbing the oscillations of the support beam 1 during its displacement by the mobile conveyors 31, 32. To release the rail rail 2, the connecting elements 13 are lowered to rest the rail rail 2 on the ground which can then be mounted on the railway track.

Grâce à la poutre de support 1 selon l'invention, il n'est plus nécessaire de recourir à un train ferroviaire ni à une poutre de support massive et dont l'encombrement est important.Thanks to the support beam 1 according to the invention, it is no longer necessary to use a railway train or a massive support beam and whose size is important.
