Description

La présente invention concerne le domaine de la maintenance des rames de transport ferroviaire. La présente invention concerne plus particulièrement un atelier de maintenance de rames de transport ferroviaire.The present invention relates to the field of the maintenance of train trains. The present invention relates more particularly to a railway train maintenance workshop.

Un problème dans le domaine de la maintenance des rames de transport ferroviaire concerne le fait que ladite maintenance est assurée au niveau de quelques sites implantés ça et là à cet effet. Il est donc nécessaire de faire transiter, à vide et à grands frais, les rames à entretenir jusqu'à un de ces sites. D'autre part, les sites de maintenance consistent encore actuellement en de très grands hangars. Ces derniers peuvent accueillir une pluralité de rames de transport ferroviaire, en même temps. Toutefois, qu'il y ait une ou plusieurs rames à entretenir, il est nécessaire de louer, chauffer et éclairer entièrement ces hangars, trop mal isolés et donc coûteux en énergie.A problem in the field of the maintenance of trains of rail transport concerns the fact that said maintenance is provided at a few sites implanted here and there for this purpose. It is therefore necessary to move, empty and at great expense, the trains to maintain to one of these sites. On the other hand, the maintenance sites still consist of very large hangars. The latter can accommodate a plurality of trainsets at the same time. However, if there are one or more trains to maintain, it is necessary to rent, heat and fully light these sheds, too poorly insulated and therefore expensive energy.

On peut citer parmi les opérations de maintenance réalisées dans ces infrastructures le contrôle et le remplacement d'éléments de partie basse (filtres, mécanismes, moteurs), d'éléments de partie médiane (portes, fenêtres, caméras, mécanismes), d'éléments de partie haute (filtres, réfrigérants), ainsi que du toit (moteurs, pantographe, câblage).Among the maintenance operations carried out in these infrastructures, the control and replacement of lower part elements (filters, mechanisms, motors), middle part elements (doors, windows, cameras, mechanisms), elements of high part (filters, refrigerants), as well as the roof (engines, pantograph, wiring).

Dans ce contexte, il est intéressant de proposer une solution qui permette de résoudre un ou plusieurs des problèmes ci-après, mettre en oeuvre l'ensemble des opérations de maintenance susmentionnées tout en s'affranchissant des phases de transit des rames de transport ferroviaire vers leur site de maintenance, de moduler la solution aux besoins de l'opération, de diminuer significativement la consommation en énergie liée à l'utilisation d'infrastructures éparses et vieillissantes. La solution proposée présente en outre d'autres avantages.In this context, it is interesting to propose a solution that makes it possible to solve one or more of the following problems, to implement all of the aforementioned maintenance operations while avoiding the transit phases of trains for rail transport to their maintenance site, to modulate the solution to the needs of the operation, to significantly reduce the energy consumption related to the use of scattered and aging infrastructures. The proposed solution has further advantages.

En référence aux figures 1, 2, 3 et 4, l'atelier de maintenance de rames (0) de transport ferroviaire selon la présente invention consiste en au moins un portique (1) mobile. Chaque portique (1) présente au moins un châssis (111) inférieur droit et un châssis (112) inférieur gauche présentant chacun au moins une barre (13) verticale. La ou les barres (13) verticales du châssis (111) inférieur droit sont verticalement télescopiques avec au moins une barre (14) creuse verticale d'un châssis (121) supérieur droit. La ou les barres (13) verticales du châssis (112) inférieur gauche sont verticalement télescopiques avec au moins une barre (14) creuse verticale d'un châssis (122) supérieur gauche. Le châssis (121) supérieur droit est transversalement télescopique au châssis (122) supérieur gauche par l'intermédiaire d'un châssis (11) central pour permettre au portique (1) de se déployer ou rétracter au moins entre une configuration déployée de travail et une configuration de transport. Les mouvements verticalement télescopiques entre les châssis (121, 122) supérieurs et les châssis (111, 112) inférieurs sont assurés préférentiellement par au moins un vérin hydraulique agencé dans les barres (14) creuses verticales et/ou les barres (13) verticales. Le portique (1) peut ainsi se déployer ou rétracter entre au moins deux dispositions verticales : une disposition verticale repliée dans laquelle le portique a par exemple une hauteur hors tout de 4,1 m et une disposition verticale dépliée dans laquelle le portique a par exemple une hauteur hors tout de 6,65 m.With reference to figures 1 , 2 , 3 and 4 , the railroad train (0) maintenance workshop according to the present invention consists of at least one mobile gantry (1). Each gantry (1) has at least one frame (111) lower right and a frame (112) lower left each having at least one bar (13) vertical. The at least one vertical bar (13) of the lower right frame (111) is vertically telescopic with at least one vertical hollow bar (14) of a right upper frame (121). The at least one vertical bar (13) of the lower left frame (112) is vertically telescopic with at least one vertical hollow bar (14) of a left upper frame (122). The upper right chassis (121) is transversely telescopic to the upper left frame (122) via a central frame (11) to allow the gantry (1) to expand or retract at least between a deployed working configuration and a transport configuration. The vertically telescopic movements between the upper chassis (121, 122) and the lower chassis (111, 112) are preferably provided by at least one hydraulic cylinder arranged in the vertical hollow bars (14) and / or the vertical bars (13). The gantry (1) can thus be deployed or retracted between at least two vertical arrangements: a folded vertical arrangement in which the gantry has for example an overall height of 4.1 m and an unfolded vertical arrangement in which the gantry, for example, an overall height of 6.65 m.

Chaque châssis (111, 112) inférieur comporte des roues (1213) autotractées et le mécanisme de traction (1214) est monté pivotant sur la structure inférieure pour se bloquer dans une position de transport où la roue (1213) est perpendiculaire à l'axe longitudinal de chaque châssis (111, 112) inférieur.Each lower frame (111, 112) has self-propelled wheels (1213) and the pull mechanism (1214) is pivotally mounted to the lower structure to lock in a transport position where the wheel (1213) is perpendicular to the axis. longitudinally of each lower frame (111, 112).

Plus particulièrement, chaque châssis (111, 112) inférieur de chaque portique (1) est constitué de deux sommiers (121) disposés longitudinalement. À titre d'exemple, chaque sommier (121) est constitué d'une poutre mécano-soudée (1211). À chacune des deux extrémités de ladite poutre (1211), sont fixés une chape (1212) de roue pour supporter une roue (1213) à bandage caoutchouc, un motoréducteur (1214) électrique de translation avec frein statique, jouant le rôle du mécanisme de traction susmentionné, et un support de couronne pour supporter une couronne de rotation conjointe de la roue et du motoréducteur. Les motoréducteurs, les couronnes de rotation et les freins statiques sont préférentiellement commandés de façon coordonnée via le pupitre de commande. Le portique (1) est ainsi équipé de moyens moteurs lui permettant une autonomie de déplacement en translation et/ou en rotation. Le portique (1) présente par exemple une longueur hors tout de 9 m, un poids total à vide 18 000 kg et une charge utile de 2000 kg. Il est nécessaire que le roulage du portique soit réalisé sur un sol bétonné ou aménagé, de préférence à plat. De plus, la vitesse de déplacement du portique est limitée à une valeur maximale de 2 km/h.More particularly, each frame (111, 112) below each gantry (1) consists of two bed bases (121) arranged longitudinally. For example, each bed base (121) consists of a welded beam (1211). At each end of said beam (1211) is secured with a clevis (1212) for supporting a wheel (1213) with a rubber tire, an electric translational gear motor (1214) with a static brake, acting as the above-mentioned traction mechanism, and a support crown to support a joint rotation crown of the wheel and the geared motor. Geared motors, rotation rings and static brakes are preferably controlled in a coordinated way via the control panel. The gantry (1) is thus equipped with motor means allowing it autonomy in displacement in translation and / or rotation. The gantry (1) has for example an overall length of 9 m, a total empty weight of 18 000 kg and a payload of 2000 kg. It is necessary that the rolling of the gantry is performed on a concrete floor or arranged, preferably flat. In addition, the speed of movement of the gantry is limited to a maximum value of 2 km / h.

Le châssis (11) central présente deux tubes (1111) creux transversaux à chacune de ses deux extrémités longitudinales. Chacun des deux châssis (121, 122) supérieurs présente une barre (1121) longitudinale sur un côté de laquelle sont perpendiculairement fixées deux barres (1122) horizontales. Chacune des deux barres (1122) horizontales d'un premier châssis supérieur s'emboîte et coulisse concomitamment et respectivement dans un de deux tubes (1111) creux situés à des extrémités longitudinales opposées du châssis (11) central. De même, chacune des deux barres (1122) horizontales du deuxième châssis supérieur s'emboîte et coulisse concomitamment et respectivement dans un des deux autres tubes (1111) creux. Le portique (1) peut ainsi se déployer ou rétracter entre au moins deux dispositions transversales : une disposition transversale repliée dans laquelle le portique a par exemple une largeur hors tout de 3 m et une disposition transversale dépliée dans laquelle le portique a par exemple une largeur hors tout de 6,8 m.The central frame (11) has two transverse hollow tubes (1111) at each of its two longitudinal ends. Each of the two upper frames (121, 122) has a longitudinal bar (1121) on one side of which two horizontal bars (1122) are perpendicularly fixed. Each of the two horizontal bars (1122) of a first upper frame fits and slides concomitantly and respectively into one of two hollow tubes (1111) located at opposite longitudinal ends of the central frame (11). Similarly, each of the two horizontal bars (1122) of the second upper frame fits and slides concomitantly and respectively in one of the other two tubes (1111) hollow. The gantry (1) can thus be deployed or retracted between at least two transverse arrangements: a folded transverse arrangement in which the gantry has for example an overall width of 3 m and an unfolded transverse arrangement in which the gantry has for example a width overall 6.8 m.

Ladite configuration de travail de chaque portique (1) correspond à un déploiement partiel ou total des éléments télescopiques verticaux et transversaux. Totalement déplié, le portique (1) prend les dimensions suivantes données à titre d'exemple :

  • une longueur hors tout de 9 m,
  • une largeur hors tout de 6,8 m,
  • une hauteur hors tout de 6,65 m,
  • un empattement de 8 m, et
  • une voie de roulement de 5,85 m.
Said working configuration of each gantry (1) corresponds to a partial or total deployment of the vertical telescopic elements and transverse. Totally unfolded, the gantry (1) takes the following dimensions given as an example:
  • an overall length of 9 m,
  • an overall width of 6.8 m,
  • an overall height of 6.65 m,
  • a wheelbase of 8 m, and
  • a 5.85 m track.

Ladite configuration de transport de chaque portique (1) correspond à un repliement total des éléments télescopiques verticaux et transversaux. Totalement replié, le portique prend les dimensions suivantes données à titre d'exemple :

  • une longueur hors tout de 9 m,
  • une largeur hors tout de 3 m, et
  • une hauteur hors tout de 4,1 m.
Said transport configuration of each gantry (1) corresponds to a total folding of the vertical and transverse telescopic elements. Completely folded, the gantry takes the following dimensions given as an example:
  • an overall length of 9 m,
  • an overall width of 3 m, and
  • an overall height of 4.1 m.

Chaque portique (1) est équipé d'au moins une passerelle (2) de travail disposée longitudinalement et constituée d'un plancher (21) en caillebottis bordé de rambardes extérieures dont une rambarde longitudinale (22) et deux portillons (23) transverses d'extrémités. À titre d'exemple non limitatif, chaque passerelle (2) est fixée au portique (1) grâce à au moins un mât (24, 25) de levage permettant sa mobilité verticale et est équipée d'un pupitre de commande du ou des mâts (24, 25) de levage pour contrôler le levage de chaque passerelle.Each gantry (1) is equipped with at least one working bridge (2) arranged longitudinally and consists of a floor (21) in curtains bordered by external railings including a longitudinal guardrail (22) and two gates (23) transverse d 'ends. By way of nonlimiting example, each bridge (2) is fixed to the gantry (1) by means of at least one lifting mast (24, 25) allowing its vertical mobility and is equipped with a control panel of the mast or poles. (24, 25) to control the lifting of each gangway.

À titre d'exemple non limitatif, le plancher (21) de chaque passerelle (2) est transversalement télescopique et chaque portillon (23) transverse d'extrémités est transversalement télescopique de façon conjointe au plancher pour permettre le déploiement de chaque passerelle (2) de travail vers le centre du portique (1). Ainsi, lorsque le portique (1) est en position de travail, ses jambages étant de part et d'autre de la rame (0) et sa structure supérieure, constituée des deux châssis (121, 122) supérieurs et du châssis (11) central, au-dessus du toit de la rame, l'espace transversal potentiellement existant entre les passerelles (2) et la rame (0) à entretenir est comblé par le déploiement des planchers (21) des passerelles. Chaque portique (1) est donc adaptable à des rames différentes en forme et/ou en dimensions.By way of nonlimiting example, the floor (21) of each bridge (2) is transversely telescopic and each gate (23) transverse ends is transversely telescopic jointly with the floor to allow the deployment of each bridge (2) working towards the center of the portico (1). Thus, when the gantry (1) is in the working position, its legs being on either side of the train (0) and its upper structure, consisting of the two frames (121, 122) and upper frame (11) central, above the roof of the train, the potentially transverse space between the bridges (2) and the train (0) to be maintained is filled by the deployment of floors (21) bridges. Each gantry (1) is therefore adaptable to different trains in shape and / or dimensions.

À titre d'exemple non limitatif, chaque portique (1) est équipé de deux paires de passerelles (2) de travail. Une première paire est située sous le portique à gauche et une deuxième paire est située sous le portique à droite. Les passerelles (2) d'une même paire sont superposées. La passerelle supérieure est fixée à deux mâts (24) de levage coordonné et chaque mât de levage est agencé à la ou aux barres (14) creuses verticales de chaque châssis supérieur. La passerelle (2) inférieure est fixée à deux mâts (25) de levage coordonné et chaque mât (25) est fixé verticalement sur le sommier (15) de chaque châssis inférieur. Il est à noter que, lorsque le portique (1) est en disposition totalement repliée, chaque passerelle (2) inférieure se trouve dans sa position verticale la plus basse et chaque passerelle (2) supérieure se trouve dans sa position verticale la plus haute, la passerelle inférieure n'étant que très légèrement surélevée par rapport au sol.By way of non-limiting example, each gantry (1) is equipped with two pairs of walkways (2) working. A first pair is located under the portico on the left and a second pair is located under the portico on the right. The bridges (2) of the same pair are superimposed. The upper gangway is attached to two coordinated lift masts (24) and each lift mast is arranged at the one or more vertical hollow bars (14) of each upper frame. The lower bridge (2) is fixed to two coordinated lifting masts (25) and each mast (25) is fixed vertically to the bed base (15) of each lower frame. It should be noted that, when the gantry (1) is in fully folded disposition, each lower bridge (2) is in its lowest vertical position and each upper bridge (2) is in its uppermost vertical position, the lower bridge is only slightly raised above the ground.

À titre d'exemple non limitatif, chaque portique (1) est équipé de deux garde-corps (3) amovibles qui permettent d'obturer la partie supérieure de la rame (0) entre deux passerelles (2) supérieures de travail situées en vis-à-vis. Par exemple, les deux passerelles supérieures, l'une à gauche, l'autre à droite, situées verticalement au niveau du toit de la rame (0) définissent de façon conjointe auxdits garde-corps (3) une surface de travail sécurisée, en particulier entièrement bordé de rambardes, cette surface comprenant le plancher télescopique de chacune des deux passerelles et le toit de la rame.By way of non-limiting example, each gantry (1) is equipped with two removable guardrails (3) which make it possible to seal the upper part of the train (0) between two upper working gangways (2) located in the form of screws. -a-vis. For example, the two upper bridges, one on the left, the other on the right, located vertically at the roof of the train (0) jointly define said guardrails (3) a secure working surface, particular fully edged railings, this surface comprising the telescopic floor of each of the two bridges and the roof of the train.

À titre d'exemple non limitatif, chaque portique (1) est équipé d'une poutre (4) de levage, constituée d'une chape (41), articulée en rotation axiale à une des barres (14) creuses verticales d'un des châssis supérieurs, un chariot (42) de translation étant monté mobile le long de la poutre (4) et un palan (43) fixé au chariot. Ainsi, des éléments lourds de la partie haute de la rame (réfrigérateurs, etc.) peuvent être aisément soulevés au dessus du toit et déposer au sol, et vice versa.By way of nonlimiting example, each gantry (1) is equipped with a lifting beam (4), consisting of a yoke (41) articulated in axial rotation with one of the vertical hollow bars (14) of a upper frames, a carriage (42) for translation being movably mounted along the beam (4) and a hoist (43) fixed to the carriage. Thus, heavy elements of the upper part of the train (refrigerators, etc.) can be easily raised above the roof and deposit on the ground, and vice versa.

À titre d'exemple non limitatif, chaque portique (1) est en outre équipé :

  • d'une alimentation électrique en puissance,
  • d'une armoire électrique de puissance et une armoire (6) électrique de commande, et
  • d'équipements de signalisation et de sécurité.
By way of non-limiting example, each gantry (1) is furthermore equipped with:
  • a power supply,
  • an electric power cabinet and an electrical control cabinet (6), and
  • signaling and security equipment.

Ces différents éléments électroniques sont interfacés entre eux selon l'art de l'informatique industrielle pour contrôler à distance, via au moins un pupitre de commande ad hoc, au moins les motoréducteurs (12) et leur frein statique, les couronnes de rotation, les mâts (24, 25) de levage, les vérins hydrauliques, la poutre (4) de levage et l'éclairage.These different electronic elements are interfaced with one another according to the art of industrial computing to remotely control, via at least one ad hoc control panel, at least the geared motors (12) and their static brake, the rotation rings, the lifting masts (24, 25), hydraulic cylinders, lifting beam (4) and lighting.

À titre d'exemple non limitatif, l'armoire électrique de puissance comprend de façon non-exhaustive un sectionneur général, un bouton de mise sous tension avec voyant, un éclairage intérieur, des transformateurs, des variateurs de fréquence avec résistances de freinage, des prises d'alimentation en 220 V.By way of non-limiting example, the electrical power cabinet includes non-exhaustively a general isolator, a power button with indicator light, interior lighting, transformers, frequency converters with braking resistors, 220 V power outlets

À titre d'exemple non limitatif, l'armoire électrique de commande comprend de façon non-exhaustive un sectionneur général, un bouton de mise sous tension avec voyant, un éclairage intérieur, un automate de gestion, des prises d'alimentation en 220 V.By way of non-limiting example, the electrical control cabinet includes non-exhaustively a general isolator, a power button with LED, indoor lighting, a management controller, 220 V power outlets .

À titre d'exemple non limitatif, les équipements de signalisation et de sécurité comprennent de façon non-exhaustive un avertisseur sonore par passerelle, deux feux à éclats, un ensemble de néons pour l'éclairage des passerelles, un ensemble d'arrêt d'urgence, un ensemble de détecteurs avec automate autorisant ou interdisant les différentes fonctions du portique, un ensemble de bandes réfléchissantes collées sur la structure, un système vidéo permettant la visualisation du côté opposé de la rame (0) lors des phases de déplacement ou d'approche du portique (1).By way of non-limiting example, the signaling and safety equipment includes non-exhaustively a buzzer by gateway, two flashing lights, a set of neons for the lighting of the bridges, a stop assembly of emergency, a set of detectors with PLC authorizing or prohibiting the various functions of the gantry, a set of reflective strips stuck on the structure, a video system for viewing the opposite side of the train (0) during the phases of displacement or gantry approach (1).

À titre d'exemple non limitatif, l'alimentation électrique en puissance consiste en un enrouleur électrique de puissance permettant l'alimentation des différents composants avec un câble d'alimentation de 30 m de longueur.By way of non-limiting example, the power supply consists of an electric power reel for feeding different components with a power cable 30 m long.

À titre d'exemple non limitatif, en références aux figures 8 et 9, chaque portique (1) en configuration de travail est en outre équipé d'un toit (51) de protection et/ou de panneaux (52) latéraux et/ou avant et/ou arrière de protection. Ces panneaux sont tous individuellement amovibles. Ils sont essentiellement constitués de cadres juxtaposés avec éléments transparents en Lexan. Le toit et les panneaux sont, par exemple, repliables sur eux-mêmes pour en faciliter le transport. De préférence, au moins un panneau latéral et/ou avant et/ou arrière de protection consiste en 2 ou 4 stores verticaux motorisés, chaque store étant constitué de cadres juxtaposés avec éléments transparents en Lexan. Par exemple, un panneau (52) est constitué de deux panneaux verticalement télescopiques pour permettre l'entrée/ la sortie d'hommes et/ou de matériel sans nécessité de démonter le panneau. Les panneaux de protection protègent non seulement du vent et de la pluie, mais permettent également de définir un espace restreint à chauffer par un moyen de chauffage intérieur du portique.By way of non-limiting example, in references to figures 8 and 9 , each gantry (1) in working configuration is further equipped with a roof (51) protection and / or panels (52) side and / or front and / or rear protection. These panels are all individually removable. They consist essentially of juxtaposed frames with transparent elements in Lexan. The roof and the panels are, for example, foldable on themselves for easy transport. Preferably, at least one side and / or front and / or rear protection panel consists of 2 or 4 motorized vertical blinds, each blind consisting of juxtaposed frames with transparent Lexan elements. For example, a panel (52) consists of two vertically telescopic panels to allow entry / exit of men and / or equipment without the need to disassemble the panel. The protection panels not only protect against wind and rain, but also define a restricted space to be heated by an interior heating means of the gantry.

À titre d'exemple non limitatif, en référence aux figures 5 et 6, le repliement vertical et transversal de chaque portique (1) depuis sa configuration de travail, ou depuis sa disposition repliée verticalement, jusqu'à sa configuration de transport est réalisé sur un chevalet (6) de stockage, de dimensions ad hoc et réalisé en profils du commerce, fixé sur la remorque d'un camion (7). Le chevalet (6) est de dimensions adaptées pour que le portique (1), disposé sur le camion (7) pour être transporté, repose à la fois sur la remorque du camion par ses roues (1213) et sur le haut du chevalet par sa structure supérieure constituée des deux châssis (121, 122) supérieure et du châssis (11) central.By way of non-limiting example, with reference to Figures 5 and 6 the vertical and transverse folding of each gantry (1) from its working configuration, or from its vertically folded disposition, to its transport configuration is carried out on a storage rack (6), of ad hoc dimensions and made in Trade profiles, attached to the trailer of a truck (7). The bridge (6) is of suitable dimensions so that the gantry (1), arranged on the truck (7) to be transported, rests both on the trailer of the truck by its wheels (1213) and on the top of the bridge by its upper structure consisting of two upper frames (121, 122) and the frame (11) central.

À titre d'exemple non limitatif, lorsque le portique (1) est en configuration de travail et doit être en configuration de transport pour, par exemple, le transporter vers une rame sur laquelle des opérations de maintenance doivent être effectuées, les opérations suivantes sont mises en oeuvre. Le portique (1) en configuration de travail roule vers le camion (7) et son chevalet (6) jusqu'à ce que les deux sommiers (15) du portique (1) se trouvent de part et d'autre de la remorque du camion (7), les passerelles (2) de travail se trouvant ainsi de part et d'autre du chevalet (6). Dans une autre mise en oeuvre possible, le camion (7) peut également se déplacer sans que le portique (1) ne roule jusqu'à ce que les deux sommiers (15) du portique (1) se trouvent de part et d'autre de la remorque du camion (7). Le portique est alors abaissé au moins verticalement grâce aux vérins hydrauliques assurant le mouvement vertical télescopique jusqu'à ce que le châssis (11) central repose sur le chevalet (6). Le portique (1) est alors replié au moins transversalement sur le chevalet (6) grâce aux roues (1213) du portique (1) qui sont tournées perpendiculairement aux sommiers (15), les passerelles (2) se trouvant ainsi engagées sous le chevalet (6). Dans une autre mise en oeuvre possible, cette dernière étape peut aussi précéder l'étape d'abaissement du châssis (11) central sur le chevalet (6). Les châssis (111, 112) inférieurs sont ensuite soulevés grâce aux vérins hydrauliques assurant le mouvement vertical télescopique jusqu'à ce que la surface de roulement des roues (1213) du portique (1) soit au moins au niveau de la surface supérieure de la remorque du camion (7). Il est alors possible de replier transversalement le portique (1) pour que les roues (1213) reposent sur la surface supérieure de la remorque du camion (7). Les roues (1213) sont préférentiellement tournées, grâce aux couronnes de rotation, pour que les motoréducteurs (1214) avant/arrière du portique se situent respectivement en avant/arrière du portique (1), réduisant ainsi l'empattement pour respecter les exigences du transport routier de matériel.By way of non-limiting example, when the gantry (1) is in the working configuration and must be in a transport configuration for, for example, transporting it to a train on which maintenance operations must be carried out, the following operations are carried out. put in artwork. The gantry (1) in working configuration rolls towards the truck (7) and its bridge (6) until the two bed bases (15) of the gantry (1) are on either side of the trailer of the truck (7), the bridges (2) working and on both sides of the bridge (6). In another possible implementation, the truck (7) can also move without the gantry (1) rolls until the two sommiers (15) of the gantry (1) are on both sides of the truck trailer (7). The gantry is then lowered at least vertically with the hydraulic cylinders ensuring the telescopic vertical movement until the frame (11) central rests on the bridge (6). The gantry (1) is then folded at least transversely on the bridge (6) thanks to the wheels (1213) of the gantry (1) which are turned perpendicularly to the sommiers (15), the catwalks (2) thus being engaged under the bridge (6). In another possible implementation, this last step can also precede the step of lowering the frame (11) central to the bridge (6). The lower frames (111, 112) are then lifted by means of the hydraulic cylinders ensuring the telescopic vertical movement until the rolling surface of the wheels (1213) of the gantry (1) is at least at the level of the upper surface of the truck trailer (7). It is then possible to fold transversely the gantry (1) so that the wheels (1213) rest on the upper surface of the truck trailer (7). The wheels (1213) are preferably rotated, thanks to the rotation rings, so that the gears (1214) front / rear gearmotors are located respectively in front / rear of the gantry (1), thus reducing the wheelbase to meet the requirements of the road transport of equipment.

À titre d'exemple non limitatif, lorsque le portique (1) est en configuration de transport et doit être en configuration de travail, les opérations suivantes sont mises en oeuvre. Le portique (1) en configuration de transport est déplié transversalement afin que les roues (1213) soient au dessus du sol. Les châssis (111, 112) inférieurs sont alors abaissés jusqu'à ce que les roues touchent le sol. Le portique (1) est alors déployé verticalement et/ou transversalement afin qu'il ne repose plus sur le chevalet (6). Le camion (7) peut alors partir. Le portique (1) est ainsi autonome pour se déplacer vers le lieu de travail.By way of non-limiting example, when the gantry (1) is in transport configuration and must be in working configuration, the following operations are implemented. The gantry (1) in transport configuration is unfolded transversely so that the wheels (1213) are above the ground. The lower frames (111, 112) are then lowered until the wheels touch the ground. The gantry (1) is then deployed vertically and / or transversely so that it no longer rests on the bridge (6). The truck (7) can then leave. The gantry (1) is thus autonomous to move to the workplace.

À titre d'exemple non limitatif, en référence à la figure 7, plusieurs portiques peuvent être assemblés par leur extrémité pour constituer un atelier de maintenance. L'atelier de maintenance est par exemple constitué d'un portique (1) unique ou de deux portiques (1) assemblés ou de trois portiques (1) assemblés ou de plus de trois portiques (1) assemblés.By way of non-limiting example, with reference to the figure 7 , several gantries can be assembled by their end to form a maintenance workshop. The maintenance workshop consists for example of a single gantry (1) or two gantries (1) assembled or three gantries (1) assembled or more than three gantries (1) assembled.

À titre d'exemple, lorsque le portique doit être utilisé pour des rames fonctionnant électriquement à l'aide de pantographes en contact avec des caténaires, il est nécessaire de ternir compte des caténaires. Dans une configuration, la rame est tractée par un moyen de traction sur une voie de service sans caténaires. Le portique (1) peut alors être utilisé normalement. Dans une autre configuration, la rame est amenée sur une voie en cul-de-sac où la caténaire est en brin mort. Le courant circulant dans la caténaire est coupé. Le portique (1) entre alors depuis le bout de la voie de telle façon que la caténaire se situe entre la rame et le châssis (11) central.For example, when the gantry is to be used for trains operating electrically using pantographs in contact with catenaries, it is necessary to tarnish the catenaries. In one configuration, the train is pulled by traction means on a service track without catenaries. The gantry (1) can then be used normally. In another configuration, the train is brought on a cul-de-sac way where the catenary is dead. The current flowing in the catenary is cut. The gantry (1) then enters from the end of the path so that the catenary is between the train and the frame (11) central.

Il doit être évident pour les personnes versées dans l'art que la présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration, mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes, et l'invention ne doit pas être limitée aux détails donnés ci-dessus.It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Therefore, the present embodiments should be considered by way of illustration, but may be modified within the scope defined by the scope of the appended claims, and the invention should not be limited to the details given above.
