Description

"Installation mobile d'entretien et de réparation de voies ferrées" "Mobile installation for maintenance and repair of railways"
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 intervention installations on railways, and in particular to track maintenance and repair installations.
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 provided, depending on the operations to be carried out, either by personnel equipped with portable tools or machines, or by means of heavy equipment installed on a circulating towed or self-propelled trolley. 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 relatively inconvenient to use, since the concept of portability covers a wide variety of tools and machines, some of which are bulky and not as light as 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 can only achieve a result in accordance with standards if their length is of the order of a meter, and whose weight is necessarily important given 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. 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.Trolley installations are generally specialized by type of intervention, and the maintenance of tracks on a given site requires the existence on this site of quite a large number of them. In addition, their weight (several hundred kilograms) makes them difficult to transport from their storage location to the track, this drawback being appreciable in the case of metropolitan railways, when they have to pass through corridors and stairs designed to be used by the public during normal operating hours of the network, and also when it is necessary to transfer them from a platform to the track and vice versa. The object of the invention is to remedy these drawbacks, and for this purpose consists of a mobile installation for the maintenance and repair of railways, of the type comprising a trolley provided with intervention equipment on the track and comprising running gear, operating in association with drive components, and control equipment, installation characterized in that it consists of several modules which are removably secured to form a line of carriages fitted with rolling members, comprising at least an intervention trolley on the track adapted to carry at least one intervention apparatus, and a control trolley comprising an apparatus for controlling the intervention apparatus, and in that the intervention trolley comprises a chassis having , seen from above, an H shape consisting of a central body and branches of substantially equal lengths extending substantially perpendicularly on either side re of this body at the ends thereof to determine on either side of the body two notches each extending between the branches being opposite one and the same side thereof, and the branches comprise removable securing means suitable for securing an intervention apparatus to each pair of branches constituted by two branches facing each other on the 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 characteristics, a small number of trolleys is sufficient to be able to carry out a wide variety of interventions, since the trolleys are not specialized and can be equipped on demand with the desired intervention apparatus. Also, the installation can be easily transported, since on the one hand the modules are removably secured and thus can be transported separately, and on the other hand the intervention apparatuses are themselves removable with respect 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 of the carriages can be constituted by the association of several modules, namely a module constituted by an H-shaped frame and two modules constituted respectively by two bearing assemblies provided with rolling members, the H-shaped chassis module being disposed between and removably secured to these two rolling members.
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 characteristic, in the case where several intervention carriages have to be assembled in a row, the immediately following intervention carriages can have a common bearing assembly, which reduces the material costs. In addition, the removability of the bearing assemblies relative to the chassis makes it possible to further reduce 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 characteristics of the invention, in order to facilitate the transfer of the carriages from a quay to a track below and vice versa, these may include retractable transverse motion undercarriages, and boxes extending transversely and telescopically extendable, fitted with jacks mounted pivoting about a horizontal axis and the rod of which comprises a clamp capable of enclosing the 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 :Other characteristics and advantages of the invention will emerge from the description which follows of embodiments given by way of nonlimiting examples and illustrated by the attached drawings in which:

The mobile installation, one of the components of which is shown in the figures, is intended for the maintenance and repair of railways such as 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 modular installation consists of modules which are removably secured to form a line of carriages 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 FIGS. 1 and 2, the installation comprises one or more intervention carts 1 such as that shown in these figures and a control carriage.
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. On peut avoir par exemple :The intervention trolley 1 is adapted to removably carry intervention apparatus 2, themselves in modular form, interchangeable, each capable of carrying out a specific intervention or task, the tasks likely to be performed being very varied. . We can have for example:
- des appareillages de décalaminage des rails, des appareillages de rectification des défauts de surface des rails,- rail descaling equipment, rail surface defect rectification equipment,
- des appareillages d'effacement de l'usure ondulatoire, - des appareillages d'aspiration des voies,- devices for erasing wave wear, - track suction devices,
- des appareillages de nettoyage haute pression,- high pressure cleaning equipment,
- des appareillages de tirefonnage et détirefonnage des rails,- railing and deregulation equipment,
- des appareillages de déboulonnage et boulonnage des rails,- equipment for unbolt and bolting of rails,
- des appareillages de mesure des défauts de surface des rails,- equipment for measuring rail surface defects,
- des appareillages d'auscultation aux ultrasons,- ultrasonic auscultation devices,
- des appareillages de rechargement des rails, - des appareillages de brossage,- rail reloading equipment, - brushing equipment,
- des appareillages de bourrage,- stuffing equipment,
- des appareillages de dépose des blochets béton et traverses,- equipment for removing concrete blocks and sleepers,
- des appareillages de pose des traverses, - des appareillages de rentaillage des traverses de voie ferrée.- equipment for laying sleepers, - gear making equipment for railway sleepers.
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 trolley (not shown in the drawings) carries control apparatus for intervention apparatus, possibly an electric or thermal engine apparatus, and a cabin for an operator whose role is to govern the control apparatus and the engine equipment.
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 . 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.In this first embodiment, the intervention carriages like the control trolley are constituted in the form of modules provided with rolling members 3 constituted by cheek wheels; here, the carriages being of relatively small weight and dimensions (of the order of a meter), two sets of wheels respectively front and rear each carrying two wheels respectively left and right, are sufficient. The intervention carriages have, seen from above when their wheels 3 rest on a horizontal ground, an H shape which is that of their chassis 4; the central body of the H is constituted by a spar 41 whose direction then extends horizontally in the vertical plane equidistant from the left and right wheels 3; this spar 41 carries at each of its two ends, two branches 42 extending laterally perpendicularly on either side of it, • the four branches 42, here substantially equal, therefore determine two approximately rectangular notches 43 on either side other from the central body 41; the branches being made vis-à-vis the same side of the body to determine the indentations, include removable securing means of intervention apparatus 2, themselves provided with securing means cooperating with them; here, the removable securing means carried by the branches of the chassis are constituted by slides 44 intended to receive rollers 21 carried by the faces of the intervention apparatus intended to come opposite 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 guide tracks thus defined between the faces of the branches 42 of the chassis and those of the intervention apparatus 2 can be reversed. Thus, each chassis 4 is adapted to receive two intervention apparatuses 2 in the form of drawers removable by lateral sliding, respectively on either side of its spar 41, these two apparatuses being intended to intervene for example on each of the two R rails of the railway.
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 location of intervention equipment relative to the rails must be respected with extreme precision, the slides 44 must be able be moved and to this end are secured to movable members of cylinders (hydraulic, electric or pneumatic) not shown, controlled by the control equipment carried by the control carriage.
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 intervention trolley therefore constitutes a rigid assembly in one piece, and, under the branches 42 of the chassis, are fixed yokes 45 carrying an axle or the axes of the wheels of the trolley.
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 arches 46 extending longitudinally above the carriage can be fixed on it, for example two arches can be fixed to the branches of the chassis respectively on either side of the spar. To these arches can be attached a transverse beam 47 facilitating the gripping of the carriage by a lifting device.
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 intervention apparatus; the actuating apparatuses 48 are electrically connected to the control apparatus carried by the control module, and electrically and possibly pneumatically or / and hydraulically to the intervention apparatus 2 which they actuate.
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 entraîner 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.Thus, the control carriage of this first embodiment comprises an apparatus for controlling the intervention apparatuses 2, acting on them by means of the actuation apparatuses 48 carried by the intervention carts 1. This control apparatus is computer controlled. Preferably, it is connected to each actuating device by a two-wire connection. The control carriage also here includes an engine switchgear mechanically connected to its bearing to drive them in rotation. Thanks to the fact that the chassis supporting the motor equipment is not rigidly linked to that of the intervention carriages 1, but by an articulated mechanical connection, the vibrations of the motor equipment are not transmitted to the intervention equipment. The control equipment is housed in a cabin intended for the operator of the installation. Advantageously, this cabin is connected to the chassis of the control carriage with the interposition of elastic seals in order to avoid parasitic noise originating from the vibrations of this chassis; also, the interior of the cabin can be kept under slight overpressure so that dust, chips, filings, droplets resulting from high-pressure cleaning, etc. cannot penetrate it and thus inconvenience the operator and disturb the operation of the control apparatus, and the elastic seals then also play the role of seals. The control trolley can also carry power supply equipment, a generator and / or a 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 entraîner 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 diagrammatically in FIGS. 3 to 6, in which the same elements as those in FIGS. 1 and 2 bear the same numerical references, an additional step is taken in the modularity of the intervention carts. Indeed, the carriages are also produced with a chassis 4 in H, and the intervention equipment 2 are still arranged in the lateral notches 43 already mentioned, but the dimension of the branches 42 of the chassis in the longitudinal direction of the carriage is smaller , due in particular to the fact that the yokes 45 carrying the shafts of the wheels are not fixed to them. Indeed, to each chassis 4, two motor modules 5 are arranged in a removable manner and on the other side of the chassis 4 respectively at the front and at the rear thereof, constituted by a cross member under which the yokes 45 are fixed, carrying the axles or the axes of the rolling members 3, and supporting an engine switchgear 50 mechanically connected to the running gear (here cheek wheels) to drive them in rotation. Instead of the chassis being, as in the first embodiment, a rigid assembly to which the rolling members are attached, here the chassis 4 is articulated to the motor modules 5 by ball joints 6 or with cardan joint or the like, and thus is suspended between two motor modules; here again, the intervention apparatuses 2 therefore do not undergo the vibrations due to the motor apparatuses. The engine modules can carry, in addition to the actuation apparatuses 48, and the engine apparatuses 50, a supply apparatus 51 such as a generator set and / or accumulator batteries for supplying the engine apparatus, as well as accessory storage boxes; alternatively, this apparatus and / or these boxes can be carried by the control trolley.
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".It can be noted that in this embodiment where the control carriage is devoid of motor equipment since motor equipment 50 is integrated into separate modules 5, and where each intervention chassis 4 is disposed between two motor modules, it is possible, in the case where several intervention chassis must be associated, to connect them by a single motor module 5 disposed between them; in other words, the successive intervention carriages have in common in particular the rolling members 3 interposed between them and their motor equipment 50. Naturally, the motor equipment 50 must all be synchronized, and can for this purpose advantageously include a motor known in the art 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 . 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'entraînement en mouvement transversal. Ce train d'entraînement 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, mus 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 entraînées en rotation par moteur, soit 1 ' installation peut être poussée ou tirée latéralement en direction de la voie par exemple comme on le verra dans la suite.Furthermore, as the intervention chassis 4 are ' suspended between two motor modules 5 by articulated securing means 6, they have a certain 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 in particular when the intervention apparatuses 2 are not in operation and when the installation must be moved in its entirety or in groups of elements; also, in addition to the detachable articulated securing means 6, the intervention chassis 4 and the motor modules 5 comprise removable rigid securing means such as keying means (not shown in the drawings), making it possible for example to transport '' a single block, an intervention chassis and two motor modules. To facilitate the lateral movements of the installation, in particular the transfer of the carriages from a quay to a track below and vice versa, the chassis 4 or the motor modules 5 can be equipped with a retractable train for driving in transverse movement. This transverse drive train is, in the second embodiment, consisting of yokes or blocks 52 arranged under the cross member of the engine module, and equipped with rollers 53, driven by hydraulic cylinders in a movement in the vertical direction; when the installation is at rest or during an intervention on the track, the blocks 52 are in the retracted position and the rollers 53 are not in contact with the ground; on the other hand, for a transverse movement, the blocks 52 are lowered by the jacks, until the rollers 53 reach the ground and moreover the rolling members in the longitudinal direction 3 are detached from it (Figure 5); then, either the rollers 53 are driven in rotation by a motor, or the installation can be pushed or pulled laterally in the direction of the track for example as will be seen below.
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. 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.Indeed, advantageously, the intervention carriages can also have a stepping device allowing their auto¬ transfer from the platform to the track and vice versa. This device comprises, in the embodiment of FIGS. 3 to 6, elongated boxes 54 extending in housings open to the lower face of the crossmembers of the motor modules 5, these boxes 54 being slidably mounted along the housings of the crossmembers, that is to say transversely to the carriage, and actuable in this direction by jacks (not visible in the drawings), preferably hydraulic, to extend the cross members selectively on either side of the motor module 5. The underside of these boxes is open, and two other preferably hydraulic jacks 55 housed between the walls of the boxes have their cylinder mounted pivoting about an axis 56 passing horizontally 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 are opposite, and a position of total extension in which their longitudinal axes are parallel and vertical and their respective rods extend downward; these two positions are defined by stops for limiting the rotational movement (not shown), cooperating with the cylinders of the jacks 55; the passage from one to the other position is automatic during the extension or retraction of the cylinder rod, thanks to the fact that the location of the axis of rotation 56 of each cylinder is chosen between the location occupied by the center of gravity of the cylinder when the latter is kept horizontal and in the fully retracted position and that occupied by the center of gravity of the same cylinder when the latter is kept horizontal and in the fully extended position. The free end of the rod of these interior jacks 55 is provided with a clamp 57 intended to grip the rail R when the jack 55 is in the vertical position. A brace 58 of bracing connects the two jacks 55 obliquely removably when the latter are in the 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'entraînement 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.Thus, when it is necessary for example to transfer from a quay to a track, a carriage consisting of a chassis 4 and two motor modules 5, after these elements have been secured by keying, the retractable trains 52, 53 of lateral drive of the engine modules are lowered and the longitudinal running gear 3 lifted off the ground; the carriage is then approached laterally from the edge of the platform below which the track extends. Then, the boxes 54 are extended so as to extend the crossmembers of the motor modules 5, above the track, orthogonally to the latter. The jacks 55 inside the boxes are controlled towards their extended position, and thus tilt about their pivot axis 56 to come to be placed vertically, and the clamps 57 of the jack rods surround the rails R while the spacer 58 bracing being positioned, the rectangle constituted by the two jacks 55 now vertical, the box 54, and the ground between the two rails R, is prevented from deforming in 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 laterally towards the track, then always pulled by these jacks, continues its suspended suspension overhang, until, these being fully retracted, the carriage is exactly above the track; then, the vertical cylinders 55 are themselves retracted as well as the transverse rolling members 53, the carriage descends until its longitudinal rolling members 3 reach the rails, and, after detaching the spacer 58, the cylinders vertical 55 are recalled to their horizontal position between the walls of the boxes. The trolleys are transferred from the track to the quay by an inverted cycle of operations.
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 the embodiments described above and shown, and we can provide others without departing from its scope.
