Description

L'invention concerne les installations mobiles d'intervention sur les voies ferrées, et notamment les installation d'entretien et de réparation des voies.The invention relates to mobile installations of intervention on the railways, and in particular the track maintenance and repair facility.

Actuellement, l'entretien et la réparation des voies ferrées sont assurés, en fonction des opérations à effectuer, soit par du personnel équipé d'outils ou de machines portables, soit au moyen d'un matériel lourd installé sur un chariot tracté ou automoteur circulant sur la voie.Currently, maintenance and repair of railways are insured, depending on the operations to be carried out either by personnel equipped with tools or portable machines, either using heavy equipment installed on a circulating towed or self-propelled cart on the way.

Les outils portables sont d'un emploi relativement malcommode, car la notion de portabilité recouvre une grande variété d'outils et de machines dont certains sont encombrants et pas aussi légers qu'il serait souhaitable, et cela est précisément le cas dans le domaine ferroviaire ; un exemple caractéristique est celui des machines pour meuler les joints de rails, lesquelles ne peuvent aboutir à un résultat conforme aux normes que si leur longueur est de l'ordre du mètre, et dont le poids est nécessairement important compte-tenu de la nature de l'outil lui-même.Portable tools are a job relatively awkward because the notion of portability covers a wide variety of tools and machines including some are bulky and not as light as it would be desirable, and this is precisely the case in the railway sector; a typical example is that of machines for grinding rail joints, which cannot lead to a result in conformity with standards only if their length is of the order of a meter, and whose weight is necessarily important given of the nature of the tool itself.

Les installations sur chariot sont généralement spécialisées par type d'intervention, et l'entretien des voies sur un site déterminé nécessite l'existence sur ce site d'un assez grand nombre d'entre eux. De plus leur poids (plusieurs centaines de kilogrammes) les rend difficiles à transporter de leur lieu d'entreposage à la voie, cet inconvénient étant sensible dans le cas des voies de chemins de fer métropolitains, lorsqu'ils doivent transiter par les couloirs et les escaliers conçus pour être empruntés par le public pendant les heures de fonctionnement normal du réseau, et également lorsqu'il est nécessaire de les transférer d'un quai à la voie et inversement. Trolley installations are generally specialized by type of intervention, and maintenance of lanes on a specific site requires existence on it quite a few of them. Furthermore their weight (several hundred kilograms) makes them difficult to transport from storage to track, this drawback being appreciable in the case of metropolitan railways, when must pass through corridors and stairs designed to be borrowed by the public during hours of normal network operation, and also when it is necessary to transfer them from a quay to the way and vice versa.

L'invention a pour but de remédier à ces inconvénients, et consiste à cet effet en une installation mobile d'entretien et de réparation de voies ferrées, du type comprenant un chariot muni d'un appareillage d'intervention sur la voie et comportant des organes de roulement, fonctionnant en association avec des organes moteurs, et un appareillage de commande, installation caractérisée en ce qu'elle est constituée de plusieurs modules solidarisés de manière amovible pour former une file de chariots munis d'organes de roulement, comprenant au moins un chariot d'intervention sur la voie adapté à porter au moins un appareillage d'intervention, et un chariot de commande comportant un appareillage de commande de l'appareillage d'intervention, et en ce que le chariot d'intervention comporte un châssis présentant, vu de dessus, une forme en H constitué d'un corps central et de branches de longueurs sensiblement égales s'étendant sensiblement perpendiculairement de part et d'autre de ce corps aux extrémités de celui-ci pour déterminer de part et d'autre du corps deux échancrures s'étendant chacune entre les branches se faisant vis-à-vis d'un même côté de celui-ci, et les branches comportent des moyens de solidarisation amovible adaptés à solidariser un appareillage d'intervention à chaque paire de branches constituée par deux branches se faisant vis-à-vis d'un même côté du corps.The object of the invention is to remedy these disadvantages, and for this purpose consists of a mobile maintenance and repair facility railway tracks, of the type comprising a carriage fitted with a intervention equipment on the track and comprising running gear, operating in association with driving parts, and a switchgear control, installation characterized in that it is consisting of several modules joined together so removable to form a line of fitted carts running gear, comprising at least one carriage of intervention on the track adapted to wear at least one intervention equipment, and a control cart comprising switchgear control apparatus and in that the intervention trolley comprises a frame having, seen from above, a shape in H consisting of a central body and branches of substantially equal lengths extending substantially perpendicularly on either side of this body to ends of it to determine from hand and on the other side of the body two notches each extending between the branches facing one side of it, and the branches include means for removable securing adapted to secure a intervention equipment for each pair of branches formed by two branches facing one same side of the body.

Grâce à ces caractéristiques, il suffit d'un faible nombre de chariots pour pouvoir exécuter une grande variété d'interventions, puisque les chariots ne sont pas spécialisés et peuvent être équipés à la demande des appareillages d'intervention désirés. Egalement, l'installation peut être aisément transportée, puisque d'une part les modules sont solidarisés de manière amovible et ainsi peuvent être transportés séparément, et d'autre part les appareillages d'intervention sont eux-mêmes amovibles par rapport au chariot d'intervention.Thanks to these features, a few trolleys to be able to run a wide variety of interventions, since the trolleys do not are not specialized and can be equipped with request the desired intervention equipment. Also, the installation can be easily transported, since on the one hand the modules are removably secured and so can be transported separately, and on the other hand intervention devices are themselves removable compared to the intervention trolley.

Selon une caractéristique de l'invention, chacun des chariots peut être constitué par l'association de plusieurs modules, à savoir un module constitué par un châssis en H et deux modules constitués respectivement par deux ensembles de roulement munis d'organes de roulement, le module de châssis en H étant disposé entre et solidarisé amoviblement à ces deux organes de roulement.According to a characteristic of the invention, each carts can be formed by the association of several modules, namely a module consisting of a H-frame and two modules made up respectively by two bearing assemblies fitted with bearing, the H-frame module being disposed between and secured removably to these two organs of rolling.

Grâce à cette caractéristique, dans le cas où plusieurs chariots d'intervention doivent être constitués à la file, les chariots d'intervention qui se suivent immédiatement peuvent avoir un ensemble de roulement en commun, ce qui réduit les coûts de matériel. De plus, l'amovibilité des ensembles de roulement par rapport aux châssis permet de réduire encore le poids des éléments à transporter.Thanks to this feature, in case several intervention carts must be formed in a row, the intervention carts which are immediately follow can have a set of joint turnover, which reduces the costs of equipment. In addition, the removability of sets of rolling relative to the chassis reduces still the weight of the elements to be transported.

Selon d'autres caractéristiques de l'invention, en vue de faciliter le transfert des chariots d'un quai à une voie en contrebas et réciproquement, ceux-ci peuvent comporter des trains de roulement en mouvement transversal escamotables, et des caissons s'étendant transversalement et extensibles télescopiquement, munis de vérins montés pivotants autour d'un axe horizontal et dont la tige comporte une pince susceptible d'enserrer les rails.According to other features of the invention, to facilitate the transfer of carts from a dock to a track below and vice versa, these may have moving undercarriages retractable transverse, and boxes extending transversely and telescopically extendable, provided cylinders mounted pivoting about a horizontal axis and the stem of which has a clamp capable of enclosing rails.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre de formes de réalisation données à titre d'exemples non limitatifs et illustrées par les dessins ci-joints dans lesquels :

  • Figure 6 is an end view of the carriage of Figure 3 during a subsequent phase of its transfer from a platform to a track.

L'installation mobile dont l'un des constituants est représenté sur les figures est destinée à l'entretien et à la réparation de voies ferrées telles que celles d'un réseau ferré métropolitain.The mobile installation of which one of the constituents is shown in the figures is intended for maintenance and repair of railways such than those of a metropolitan rail network.

Selon l'invention, cette installation, modulaire, est constituée de modules solidarisés de manière amovible pour former une file de chariots comprenant au moins un chariot d'intervention et un chariot de commande.According to the invention, this installation, modular, consists of integral modules of removable way to form a line of carts comprising at least one intervention trolley and one control trolley.

Dans une première forme de réalisation, illustrée par les figures 1 et 2, l'installation comprend un ou plusieurs chariots d'intervention 1 tels que celui représenté sur ces figures et un chariot de commande.In a first embodiment, illustrated by figures 1 and 2, the installation includes one or more intervention carts 1 such than the one shown in these figures and a carriage ordered.

Le chariot d'intervention 1 est adapté à porter de manière amovible des appareillages d'intervention 2, eux-mêmes sous forme modulaire, interchangeables, susceptibles d'effectuer chacun une intervention ou tâche spécifique, les tâches susceptibles d'être effectuées étant très variées.The intervention trolley 1 is suitable for carrying removably intervention equipment 2, themselves in modular form, interchangeable, likely to each perform an intervention or specific task, tasks likely to be being very varied.

On peut avoir par exemple :

  • des appareillages de décalaminage des rails, des appareillages de rectification des défauts de surface des rails,

  • des appareillages de bourrage,
  • des appareillages de dépose des blochets béton et traverses,
  • des appareillages de pose des traverses,
  • des appareillages de rentaillage des traverses de voie ferrée.

  • wave wear erasing devices,
  • track suction equipment,
  • high pressure cleaning equipment,
  • drawing and deregulation equipment for the rails,
  • equipment for unbuttoning and bolting rails,

  • ultrasonic auscultation devices,
  • rail reloading devices,
  • brushing devices,
  • tamping equipment,
  • equipment for removing concrete blocks and sleepers,
  • sleeper installation equipment,
  • railroad tacking equipment.

Le chariot de commande (non représenté sur les dessins) porte un appareillage de commande des appareillages d'intervention, éventuellement un appareillage moteur électrique ou thermique, et une cabine pour un opérateur dont le rôle est de régir l'appareillage de commande et l'appareillage moteur.The control carriage (not shown in the drawings) carries control gear for intervention equipment, possibly a electrical or thermal engine equipment, and cabin for an operator whose role is to govern control gear and engine gear.

Dans cette première forme de réalisation, les chariots d'intervention comme le chariot de commande sont constitués sous la forme de modules munis d'organes de roulement 3 constitués par des roues à joue ; ici, les chariots étant de poids et de dimensions relativement réduites (de l'ordre du mètre), deux trains de roues respectivement avant et arrière portant chacun deux roues respectivement gauche et droite, sont suffisants. In this first embodiment, the intervention carts like the order cart are made in the form of modules fitted with components rolling 3 constituted by cheek wheels; here, the carriages being of weight and dimensions relatively small (around one meter), two trains of front and rear wheels respectively, each carrying two wheels respectively left and right, are enough.

Les chariots d'intervention présentent, vus de dessus lorsque leurs roues 3 reposent sur un sol horizontal, une forme en H qui est celle de leur châssis 4 ; le corps central du H est constitué par un longeron 41 dont la direction s'étend alors horizontalement dans le plan vertical équidistant des roues gauche et droite 3 ; ce longeron 41 porte à chacune de ses deux extrémités, deux branches 42 s'étendant latéralement perpendiculairement de part et d'autre de lui ; les quatre branches 42, ici sensiblement égales, déterminent donc deux échancrures 43 approximativement rectangulaires de part et d'autre du corps central 41 ; les branches se faisant vis-à- vis d'un même côté du corps pour déterminer les échancrures, comportent des moyens de solidarisation amovible des appareillages d'intervention 2, eux-mêmes dotés de moyens de solidarisation coopérant avec ceux-ci ; ici, les moyens de solidarisation amovible portés par les branches du châssis sont constitués par des glissières 44 destinées à recevoir des galets 21 portés par les faces de l'appareillage d'intervention prévues pour venir en regard des faces des branches 42 du châssis se faisant vis-à-vis d'un même côté du corps ; bien entendu, la nature des chemins de guidage ainsi définis entre les faces des branches 42 du châssis et celles de l'appareillage d'intervention 2 peut être inversée. Ainsi, chaque châssis 4 est adapté à recevoir deux appareillages d'intervention 2 sous la forme de tiroirs amovibles par coulissement latéral, respectivement de part et d'autre de son longeron 41, ces deux appareillages étant destinés à intervenir par exemple sur chacun des deux rails R de la voie ferrée.The intervention carts show, seen from above when their wheels 3 rest on a ground horizontal, an H shape which is that of their chassis 4; the central body of the H consists of a spar 41 whose direction then extends horizontally in the vertical plane equidistant from the left and right wheels 3; this spar 41 carries to each of its two ends, two branches 42 extending laterally perpendicularly on either side of it; the four branches 42, here substantially equal, determine so two notches 43 approximately rectangular on either side of the central body 41; the branches facing each other on the same side of the body to determine the notches, have removable means for securing the equipment intervention 2, themselves equipped with solidarity cooperating with them; here the means removable fastening carried by the branches of the chassis are constituted by slides 44 intended to receive rollers 21 carried by the faces of intervention equipment planned to come in look at the faces of the branches 42 of the chassis being vis-à-vis the same side of the body; of course the nature of the guideways thus defined between the faces of the branches 42 of the chassis and those of intervention equipment 2 can be reversed. Thus, each chassis 4 is adapted to receive two intervention equipment 2 in the form of drawers removable by lateral sliding, respectively on either side of its spar 41, these two apparatus being intended to intervene for example on each of the two rails R of the track.

Comme le plus souvent, la position et l'emplacement des appareillages d'intervention par rapport aux rails doivent être respectés avec une extrême précision, les glissières 44 doivent pouvoir être déplacées et à cette fin sont solidarisées à des organes mobiles de vérins (hydrauliques, électriques ou pneumatiques) non représentés, asservis depuis l'appareillage de commande porté par le chariot de commande.As most often, the position and the location of intervention equipment by compared to the rails must be met with a extreme precision, the slides 44 must be able be moved and to this end are joined to mobile actuators (hydraulic, electric or tires) not shown, slaved since the control equipment carried by the trolley ordered.

Dans cette forme de réalisation, le chariot d'intervention constitue donc un ensemble rigide en une seule pièce, et, sous les branches 42 du châssis, sont fixées des chapes 45 portant un essieu ou les axes des roues du chariot.In this embodiment, the carriage intervention therefore constitutes a rigid whole in one single piece, and, under the branches 42 of the chassis, are fixed yokes 45 carrying an axle or the axes of carriage wheels.

Un ou plusieurs arceaux raidisseurs 46 s'étendant longitudinalement au-dessus du chariot peuvent être fixés sur lui, par exemple deux arceaux peuvent être fixés aux branches du châssis respectivement de part et d'autre du longeron. A ces arceaux peut être fixée une poutre transversale 47 facilitant la préhension du chariot par un engin de levage.One or more stiffening hoops 46 extending longitudinally above the carriage can be fixed on it, for example two poles can be attached to the frame arms respectively on either side of the beam. At these hoops can be fixed a transverse beam 47 facilitating the gripping of the carriage by a lifting.

Des branches 42 du châssis portent également des coffrets contenant un appareillage 48 d'actionnement des appareillages d'intervention ; les appareillages d'actionnement 48 sont reliés électriquement à l'appareillage de commande porté par le module de commande, et électriquement et éventuellement pneumatiquement ou/et hydrauliquement à l'appareillage d'intervention 2 qu'ils actionnent.Branches 42 of the chassis also carry boxes containing an apparatus 48 for actuating the intervention apparatus; equipment actuator 48 are electrically connected to the control gear carried by the module control, and electrically and possibly pneumatically or / and hydraulically to the switchgear intervention 2 that they operate.

Ainsi, le chariot de commande de cette première forme de réalisation comporte un appareillage de commande des appareillages d'intervention 2, agissant sur eux par l'intermédiaire des appareillages d'actionnement 48 portés par les chariots d'intervention 1. Cet appareillage de commande est piloté par ordinateur. De préférence, il est relié à chaque appareillage d'actionnement par une liaison à deux fils. Le chariot de commande comporte également ici un appareillage moteur relié mécaniquement à ses organes de roulement pour les entraíner en rotation. Grâce au fait que le châssis supportant l'appareillage moteur n'est pas lié rigidement à celui des chariots d'intervention 1, mais par une liaison mécanique articulée, les vibrations de l'appareillage moteur ne sont pas transmises aux appareillages d'intervention. L'appareillage de commande est logé dans une cabine destinée à l'opérateur de l'installation. Avantageusement, cette cabine est reliée au châssis du chariot de commande avec interposition de joints élastiques afin d'éviter les bruits parasites provenant des vibrations de ce châssis ; également, l'intérieur de la cabine peut être maintenu en légère surpression de telle sorte que les poussières, copeaux, limailles, gouttelettes résultant d'un nettoyage haute-pression, etc. ne puissent y pénétrer et ainsi incommoder l'opérateur et perturber le fonctionnement de l'appareillage de commande, et les joints élastiques jouent alors également le rôle de joints d'étanchéité. Le chariot de commande peut également porter un appareillage d'alimentation, groupe électrogène et/ou batterie d'accumulateurs.So the control carriage of this first embodiment includes an apparatus for control of intervention equipment 2, acting on them through the devices 48 carried by intervention carts 1. This control device is controlled by computer. Preferably, it is connected to each actuating apparatus by a two-wire connection. The control cart also includes a motor equipment mechanically connected to its bearing to drive them in rotation. Thanks to the fact that the chassis supporting the motor equipment is not not rigidly linked to that of the intervention carts 1, but by an articulated mechanical connection, the vibrations of the switchgear are not transmitted to intervention equipment. The control gear is housed in a cabin intended for the operator of the installation. Advantageously, this cabin is connected to the chassis of the control trolley with interposition of seals elastic to avoid unwanted noise from vibrations of this chassis; also, the interior of the cabin can be kept under slight overpressure so that dust, shavings, filings, droplets resulting from high pressure cleaning, etc. cannot enter it and thus inconvenience the operator and disrupt the operation of control gear, and elastic seals then also play the role of seals. The control cart can also carry a power supply equipment, generator and / or storage battery.

Dans une deuxième forme de réalisation schématisée sur les figures 3 à 6, sur lesquelles les mêmes éléments que ceux des figures 1 et 2 portent les mêmes références numériques, un pas supplémentaire est franchi dans la modularité des chariots d'intervention. En effet, les chariots sont également réalisés avec un châssis 4 en H, et les appareillages d'intervention 2 sont encore disposés dans les échancrures latérales 43 déjà mentionnées, mais la dimension des branches 42 du châssis dans la direction longitudinale du chariot est plus faible, du fait, en particulier, que les chapes 45 portant les arbres des roues ne sont pas fixées à elles. En effet, à chaque châssis 4, sont solidarisés de manière amovible deux modules moteurs 5 disposés de part et d'autre du châssis 4 respectivement à l'avant et à l'arrière de celui-ci, constitués par une traverse sous laquelle sont fixées les chapes 45 portant les essieux ou les axes des organes de roulement 3, et supportant un appareillage moteur 50 relié mécaniquement aux organes de roulement (ici des roues à joue) pour les entraíner en rotation. Au lieu que, comme dans la première forme de réalisation, le châssis soit un ensemble rigide auquel sont solidarisés les organes de roulement, ici le châssis 4 est articulé aux modules moteurs 5 par des joints 6 à rotule ou à la cardan ou analogues, et ainsi est suspendu entre deux modules moteurs ; là encore, les appareillages d'intervention 2 ne subissent donc pas les vibrations dues aux appareillages moteurs. Les modules moteurs peuvent porter, en plus des appareillages d'actionnement 48, et de l'appareillage moteur 50, un appareillage d'alimentation 51 tel qu'un groupe électrogène ou/et des batteries d'accumulateurs pour alimenter l'appareillage moteur, ainsi que des coffrets de rangement d'accessoires ; en alternative, cet appareillage et/ou ces coffrets peuvent être portés par le chariot de commande.In a second embodiment shown schematically in Figures 3 to 6, in which the same elements as those of FIGS. 1 and 2 carry the same reference numbers, one more step is crossed in the modularity of the intervention carts. Indeed, the carts are also made with a chassis 4 in H, and intervention equipment 2 are still arranged in the lateral notches 43 already mentioned, but the size of the branches 42 of the chassis in the longitudinal direction of the carriage is weaker, in particular due to the fact that the yokes 45 bearing the shafts of the wheels are not attached to them. Indeed, to each chassis 4, are secured to removably two motor modules 5 arranged on the side and other of the chassis 4 respectively at the front and at the back of it, formed by a cross under which are fixed the yokes 45 carrying the axles or the axes of the rolling members 3, and supporting a motor equipment 50 mechanically connected to the components rolling (here cheek wheels) to train them in rotation. Instead, as in the first form the chassis is a rigid assembly to which the running gear are attached, here the chassis 4 is articulated to the motor modules 5 by ball joints 6 or cardan or the like, and so is suspended between two motor modules; there again, the intervention equipment 2 are therefore not subjected to vibrations due to motor equipment. Modules motors can carry, in addition to switchgear actuator 48, and the motor equipment 50, a supply apparatus 51 such as a group generator or / and storage batteries for supply the motor equipment, as well as boxes accessory storage; alternatively, this switchgear and / or these boxes can be carried by the control cart.

On peut noter que dans cette forme de réalisation où le chariot de commande est dénué d'appareillage moteur puisque des appareillages moteurs 50 sont intégrés à des modules 5 séparés, et où chaque châssis d'intervention 4 est disposé entre deux modules moteurs, il est possible, dans le cas où plusieurs châssis d'intervention doivent être associés, de les relier par un unique module moteur 5 disposé entre eux ; en d'autres termes, les chariots d'intervention successifs ont en commun notamment les organes de roulement 3 interposés entre eux et leurs appareillages moteur 50. Naturellement, les appareillages moteurs 50 doivent être tous synchronisés, et peuvent à cette fin avantageusement comporter un moteur connu dans la technique sous le nom de "moteur brushless".We can note that in this form of realization where the control carriage is stripped of motor equipment since motor equipment 50 are integrated into separate modules 5, and where each intervention chassis 4 is arranged between two modules motors, it is possible, in case several intervention chassis must be associated, connect by a single motor module 5 disposed between them; in other words, the intervention carts successive have in common in particular the organs of bearing 3 interposed between them and their equipment engine 50. Naturally, engine 50 must all be synchronized, and can for this purpose advantageously include a motor known in the technique under the name of "brushless motor".

Par ailleurs, comme les châssis d'intervention 4 sont suspendus entre deux modules moteurs 5 par des moyens de solidarisation articulée 6, ils possèdent un certain nombre de degrés de liberté qui sont utiles pour diverses interventions sur les voies ; en revanche, l'existence de tout ou partie de ces degrés de liberté peut être un inconvénient notamment quand les appareillages d'intervention 2 ne sont pas en fonctionnement et quand l'installation doit être mue dans sa totalité ou par groupes d'éléments ; aussi, en plus des moyens de solidarisation articulée amovible 6, les châssis d'intervention 4 et les modules moteurs 5 comportent des moyens de solidarisation rigide amovible tels que des moyens de clavetage (non représentés sur les dessins), permettant par exemple de transporter d'un seul bloc un châssis d'intervention et deux modules moteurs.Furthermore, like the intervention chassis 4 are suspended between two motor modules 5 by articulated securing means 6, they have a number of degrees of freedom which are useful for various interventions on the tracks; on the other hand, the existence of all or part of these degrees of freedom can be a drawback especially when the intervention equipment 2 are not in operation and when the installation must be moved in its entirety or in groups of elements; also in plus removable articulated securing means 6, the intervention chassis 4 and the engine modules 5 have removable rigid fastening means such as keying means (not shown in the drawings), allowing for example to transport from single block an intervention chassis and two modules engines.

Pour faciliter les mouvements latéraux de l'installation, notamment le transfert des chariots d'un quai à une voie en contrebas et inversement, les châssis 4 ou les modules moteurs 5 peuvent être équipés d'un train escamotable d'entraínement en mouvement transversal. Ce train d'entraínement transversal est, dans la deuxième forme de réalisation, constitué de chapes ou blocs 52 disposés sous la traverse du module moteur, et équipés de roulettes 53, mûs par vérins hydrauliques dans un mouvement en direction verticale ; lorsque l'installation est au repos ou lors d'une intervention sur la voie, les blocs 52 sont en position rétractée et les roulettes 53 ne sont pas en contact avec le sol ; en revanche, en vue d'un mouvement transversal, les bloc 52 sont descendus par les vérins, jusqu'à ce que les roulettes 53 atteignent le sol et de plus les organes de roulement en direction longitudinale 3 soient décollés de celui-ci (figure 5) ; alors, soit les roulettes 53 sont entraínées en rotation par moteur, soit l'installation peut être poussée ou tirée latéralement en direction de la voie par exemple comme on le verra dans la suite.To facilitate lateral movements of installation, including the transfer of carts from one one-way platform below and vice versa, the chassis 4 or the motor modules 5 can be fitted with a retractable moving train transverse. This transverse drive train is, in the second embodiment, consisting of screeds or blocks 52 arranged under the cross member of the module motor, and fitted with 53 castors, driven by cylinders hydraulics in a vertical direction movement; when the installation is at rest or during a intervention on the track, blocks 52 are in position retracted and the casters 53 are not in contact with the ground; on the other hand, in view of a movement transverse, the blocks 52 are lowered by the jacks, until the rollers 53 reach the ground and plus the running gear in the longitudinal direction 3 are detached from it (Figure 5); so either the rollers 53 are driven in rotation by a motor, either the installation can be pushed or pulled laterally towards the track for example as we will see it later.

En effet, avantageusement, les chariots d'intervention peuvent également posséder un dispositif de franchissement de degrés permettant leur auto-transfert du quai à la voie et inversement.Indeed, advantageously, the carts can also have a device of crossing degrees allowing their self-transfer from platform to track and vice versa.

Ce dispositif comporte, dans la forme de réalisation des figures 3 à 6, des caissons 54 allongés s'étendant dans des logements ouverts à la face inférieure des traverses des modules moteurs 5, ces caissons 54 étant montés coulissants le long des logements des traverses, c'est-à-dire transversalement au chariot, et actionnables dans cette direction par des vérins (non visibles sur les dessins) de préférence hydrauliques pour prolonger télescopiquement les traverses sélectivement de l'un ou de l'autre côté du module moteur 5. La face inférieure de ces caissons est ouverte, et deux autres vérins de préférence hydrauliques 55 logés entre les parois des caissons ont leur cylindre monté pivotant autour d'un axe 56 traversant horizontalement le caisson 54 et porté par ces parois ; ces vérins 55 intérieurs aux caissons 54 sont mobiles en pivotement entre une position de rétraction totale dans laquelle leurs axes longitudinaux sont horizontaux et alignés et leurs tiges respectives se font vis-à-vis, et une position d'extension totale dans laquelle leurs axes longitudinaux sont parallèles et verticaux et leurs tiges respectives s'étendent vers le bas ; ces deux positions sont définies par des butées de limitation du mouvement de rotation (non représentées), coopérant avec les cylindres des vérins 55 ; le passage de l'une à l'autre position est automatique lors de l'extension ou de la rétraction de la tige du vérin, grâce au fait que l'emplacement de l'axe de rotation 56 de chaque vérin est choisi entre l'emplacement qu'occupe le centre de gravité du vérin lorsque celui-ci est maintenu horizontal et en position de rétraction totale et celui qu'occupe le centre de gravité du même vérin lorsque celui-ci est maintenu horizontal et en position d'extension totale. L'extrémité libre de la tige de ces vérins intérieurs 55 est munie d'une pince 57 destinée à enserrer le rail R lorsque le vérin 55 est en position verticale. Une entretoise 58 de contreventement relie en oblique amoviblement les deux vérins 55 lorsque ceux-ci sont en position verticale.This device comprises, in the form of embodiment of FIGS. 3 to 6, elongated boxes 54 extending into housings open to the face lower cross members of the motor modules 5, these boxes 54 being slidably mounted along the sleeper housings, i.e. transversely to the carriage, and actuable in this direction by cylinders (not visible in the drawings) preferably hydraulics to extend telescopically the selectively sleepers on either side of the motor module 5. The underside of these boxes is open, and preferably two other cylinders hydraulic 55 housed between the walls of the boxes have their cylinder mounted pivoting about an axis 56 horizontally passing through the box 54 and carried by these walls; these jacks 55 inside the boxes 54 are pivotally movable between a position of total retraction in which their longitudinal axes are horizontal and aligned and their respective rods face each other, and a position of total extension in which their longitudinal axes are parallel and vertical and their respective rods extend towards the bottom ; these two positions are defined by stops limiting the rotational movement (no shown), cooperating with the cylinders of the cylinders 55; the transition from one to the other position is automatic when extending or retracting the cylinder rod, thanks to the fact that the location of the axis of rotation 56 of each cylinder is chosen between the location of the cylinder's center of gravity when it is kept horizontal and in position of total retraction and that occupied by the center of gravity of the same cylinder when it is maintained horizontal and in the fully extended position. The free end of the rod of these internal cylinders 55 is fitted with a clamp 57 intended to grip the rail R when the jack 55 is in the vertical position. A brace 58 bracing connects obliquely detachably the two jacks 55 when these are in vertical position.

Ainsi, lorsqu'il est nécessaire par exemple de transférer d'un quai à une voie, un chariot constitué d'un châssis 4 et de deux modules moteurs 5, après solidarisation de ces éléments par clavetage, les trains escamotables 52, 53 d'entraínement latéral des modules moteurs sont descendus et les organes de roulement longitudinal 3 décollés du sol ; le chariot est ensuite approché latéralement du bord du quai en contrebas duquel s'étend la voie. Puis, les caissons 54 sont étendus de manière à prolonger les traverses des modules moteurs 5, au-dessus de la voie, orthogonalement à celle-ci. Les vérins 55 intérieurs des caissons sont commandés vers leur position d'extension, et ainsi basculent autour de leur axe de pivotement 56 pour venir se placer verticalement, et les pinces 57 des tiges de vérin viennent enserrer les rails R tandis que l'entretoise 58 de contreventement étant positionnée, le rectangle constitué par les deux vérins 55 maintenant verticaux, le caisson 54, et le sol entre les deux rails R, est empêché de se déformer en parallélogramme ; les vérins de commande télescopique des caissons 54 sont rétractés, mais comme les caissons sont immobilisés par le fait que les pinces 57 enserrent les rails, le chariot roule latéralement vers la voie, puis toujours tiré par ces vérins, continue sa course suspendu en porte-à-faux, jusqu'à ce que, ceux-ci étant entièrement rétractés, le chariot soit exactement au-dessus de la voie ; alors, les vérins verticaux 55 sont eux-mêmes rétractés ainsi que les organes de roulement transversal 53, le chariot descend jusqu'à ce que ses organes de roulement longitudinal 3 atteignent les rails, et, après décrochage de l'entretoise 58, les vérins verticaux 55 sont rappelés vers leur position horizontale entre les parois des caissons. Le transfert des chariots de la voie au quai s'effectue par un cycle d'opérations inversé.So when it is necessary for example to transfer from a quay to a track, a cart made up a chassis 4 and two motor modules 5, after joining of these elements by keying, the trains retractable 52, 53 for lateral drive of the modules engines are down and the running gear longitudinal 3 lifted off the ground; the cart is then approached laterally from the edge of the platform below from which the way extends. Then, the boxes 54 are extended so as to extend the cross members of the modules motors 5, above the track, orthogonally to this one. The 55 cylinders inside the boxes are commanded to their extended position, and so swing around their pivot axis 56 to come stand vertically, and the clips 57 of the rods cylinder grip the R rails while the brace 58 of bracing being positioned, the rectangle formed by the two cylinders 55 now vertical, box 54, and the floor between the two rails R, is prevented from deforming into a parallelogram; the telescopic control cylinders of the boxes 54 are retracted, but since the boxes are immobilized by the fact that the clamps 57 grip the rails, the carriage rolls sideways towards the track, then always pulled by these jacks, continues its suspended course in overhang, until, these being entirely retracted, the carriage is exactly above the track; then, the vertical cylinders 55 are themselves retracted as well as the transverse running gear 53, the carriage descends until its organs of longitudinal bearing 3 reach the rails, and after release of the spacer 58, the vertical cylinders 55 are recalled to their horizontal position between the box walls. The transfer of the carts from the track at the quay is carried out by a cycle of operations reversed.

Bien entendu, l'invention n'est pas limitée aux formes de réalisation ci-dessus décrites et représentées, et on pourra en prévoir d'autres sans sortir de son cadre.Of course, the invention is not limited to embodiments described above and represented, and we can foresee others without get out of its frame.
