Description

Dispositif de levage et d'entraînement en pivotement pour la structure ferroviaire porteuse d'un wagon de transport combiné rail/route. Device for lifting and pivoting drive for the railway structure carrying a combined rail / road transport wagon.
L'invention se rapporte à 'un dispositif de levage et d'entraînement en pivotement pour la structure ferroviaire pivotante porteuse de la charge routière d'un wagon de transport combiné rail/route.The invention relates to a pivoting lifting and driving device for the pivoting railway structure carrying the road load of a combined rail / road transport wagon.
Les wagons de transport combiné rail/route à structure ferroviaire pivotante porteuse d'une charge routière font appel pour la plupart à des organes moteurs internes pour assurer 1 ' entraînement en pivotement de la structure ferroviaire porteuse pivotante. II s'agit en général de moyens simples embarqués, propres au wagon utilisant l'énergie disponible à bord.Most rail / road transport wagons with a pivoting rail structure carrying a road load mostly use internal drive members to ensure the pivoting drive of the pivoting supporting rail structure. These are generally simple on-board means, specific to the wagon using the energy available on board.
On peut mentionner à cet effet le dépôt PCT n°8102142 au nom de BEHRENS. Ces solutions antérieures prévoient aussi des mécanismes réducteurs et d'accouplement pour transformer le mouvement rotatif de la source mécanique en mouvement de pivotement.We can mention for this purpose the PCT filing n ° 8102142 in the name of BEHRENS. These previous solutions also provide reduction and coupling mechanisms to transform the rotary movement of the mechanical source into a pivoting movement.
Ces solutions présentent plusieurs inconvénients importants.These solutions have several significant drawbacks.
Le premier concerne la consommation d'énergie à bord qui ne peut pas être conséquente et de ce fait apporte une lenteur dans les manoeuvres en raison de la sous-motorisation des équipements. De plus, cette consommation en énergie est pénalisante pour les autres appareils à bord et notamment ceux liés à la sécurité.The first concerns the energy consumption on board which cannot be substantial and therefore brings a slowness in the maneuvers due to the underpowering of the equipment. In addition, this energy consumption is penalizing for other devices on board and especially those related to safety.
Le second concerne le coût de ces organes. Le système en nécessite au moins un exemplaire par wagon non réutilisable pour d'autres wagons. Le troisième inconvénient porte sur l'amplitude de la manoeuvre de pivotement. En effet, aucun des dispositifs antérieurs ne permet de libérer toutes les extrémités de la structure ferroviaire porteuse et par conséquent d'arriver à une plus grande amplitude dans les mouvements de pivotement. L'importance de cette amplitude de pivotement conditionne le confort dans les manoeuvres et par là même l'efficacité, la sécurité et la rapidité de celles-ci.The second concerns the cost of these organs. The system requires at least one copy per wagon that cannot be reused for other wagons. The third drawback relates to the amplitude of the pivoting maneuver. Indeed, none of the prior devices allows to release all the ends of the load-bearing railway structure and therefore arrive at a greater amplitude in the pivoting movements. The importance of this amplitude of pivoting conditions the comfort in the maneuvers and thereby the efficiency, the safety and the speed of these.
Le dernier inconvénient se rapporte à l'entretien spécifique de ces organes qui entraîne un surcoût important de la maintenance des wagons.The last drawback relates to the specific maintenance of these bodies, which results in a significant additional cost for the maintenance of the wagons.
L'invention a pour but de remédier à tous ces inconvénients simultanément tout en gardant une bonne souplesse d'utilisation.The invention aims to remedy all these drawbacks simultaneously while retaining good flexibility of use.
A cet effet, l'invention se rapporte à un dispositif combiné de levage et d'entraînement en pivotement pour la structure ferroviaire porteuse de la charge routière dans le cadre du transport combiné rail/route.To this end, the invention relates to a combined lifting and pivoting device for the railway structure carrying the road load in the context of combined rail / road transport.
Ce dispositif se caractérise par au moins un moyen d'élévation et au moins un moyen de roulement motorisé présents au sol venant en contact d'appui et de levage puis de roulement d'entraînement en pivotement avec au moins une zone de sous-face d'au moins une extrémité de la structure ferroviaire porteuse en vue du déplacement de pivotement d'au moins cette extrémité pour les opérations de chargement/déchargement de la charge routière dans ou hors de la structure ferroviaire porteuse.This device is characterized by at least one lifting means and at least one motorized rolling means present on the ground coming into bearing and lifting contact and then pivoting drive rolling with at least one underside area d 'at least one end of the carrying railway structure for the pivotal movement of at least this end for the loading / unloading operations of the road load in or out of the carrying railway structure.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description qui suit, donnée à titre d'exemple et accompagnée des dessins dans lesquels :Other characteristics and advantages of the invention will appear in the description which follows, given by way of example and accompanied by the drawings in which:

Le dispositif d'élévation décrit ci-après réalisant aussi l'abaissement de la structure ferroviaire porteuse, il serait plus complet de l'appeler dispositif de levage-abaissement. Pour éviter des lourdeurs et dans un esprit de simplification on se contentera de le qualifier ci-après uniquement de dispositif de levage pour cette fonction. Il assure aussi l'entraînement en pivotement de la structure ferroviaire porteuse. En se référant à la figure 1, le dispositif combiné de levage et d'entraînement en pivotement 1 est prévu pour être installé sur une voie ferrée 2 présentant deux quais 3 et 4 de chargement/déchargement se développant de part et d ' autre de la voie 2. Le dispositif 1 est monté de préférence entre les deux rails d'un poste 5 de chargement/déchargement représenté dans sa généralité sur la figure 1. Selon le type de wagon, comme celui utilisé pour le poste représenté sur la figure 1, il peut s'avérer nécessaire de prévoir deux dispositifs de levage tels que 1, l'un pour chacune des extrémités d'une structure porteuse ferroviaire 6. En effet, dans le cas représenté, cette structure porteuse est soulevée simultanément par ses deux extrémités et pivotée autour d'un centre de pivotement central non représenté. Il peut s'agir aussi d'un pivotement autour d'un centre de pivotement d • extrémité.The lifting device described below also realizes the lowering of the carrying railway structure, it would be more complete to call it lifting-lowering device. To avoid heaviness and in the spirit of simplification, we will only describe it below as a lifting device for this function. It also ensures the pivoting drive of the supporting railway structure. Referring to FIG. 1, the combined lifting and pivoting device 1 is designed to be installed on a railroad track 2 having two loading and unloading platforms 3 and 4 developing on either side of the track 2. The device 1 is preferably mounted between the two rails of a loading / unloading station 5 generally represented in FIG. 1. According to the type of wagon, like that used for the station shown in FIG. 1, it may prove necessary to provide two lifting devices such as 1, one for each of the ends of a railway carrying structure 6. Indeed, in the case shown, this support structure is lifted simultaneously by its two ends and pivoted around a central pivot center not shown. It can also be a pivoting around an end pivoting center.
Pour des raisons de simplification car les deux dispositifs 1 de levage et d'entraînement en pivotement sont identiques, il ne sera décrit ci-après qu'un seul dispositif. Ce dispositif 1 est complété par une série de plusieurs rouleaux porteurs et de préférence entraîneurs par exemple deux trains 7 et 8 de trois rouleaux montés sur un quai respectivement 3 et 4 et destinés à recevoir, à reprendre et éventuellement mais non nécessairement à continuer à faire pivoter la structure ferroviaire porteuse 6 par son fond dès que son porte-à-faux vers le quai dépasse une certaine limite, ceci pour arriver à une bonne stabilité et sécurité des mouvements de pivotement. Les rouleaux de ces trains 7 et 8 de rouleaux sont logés dans un évidemment de la structure du quai comme représenté sur la figure 1 à une distance convenable du bord du quai. Ils dépassent légèrement de la surface du quai pour reprendre le fond de la structure porteuse en porte-à- faux sur le quai. Ces rouleaux de préférence motorisés sont des ensembles formés chacun d'un cylindre tournant 9 de forme légèrement tronconique pour bénéficier des différences de vitesses circonférencielles d'une extrémité à l'autre en vue d'éviter les glissements. Leur surface latérale est de préférence recouverte d'une bande métallique de roulement 10 arrivant en contact avec une piste d'appui et de roulement 11 (figure 4) propre à au moins une extrémité de la structure ferroviaire porteuse 6 du wagon. Ils comportent un bloc-moteur électrique 12 d'entraînement du rouleau en rotation dans l'axe du rouleau. Comme indiqué, les structures ferroviaires porteuses 6 présentent à au moins une de leurs extrémités en sous-face une piste plane d'appui et de roulement 11, par exemple sous la forme d'une plaque rapportée ou toute autre forme de réalisation. En raison du caractère pivotant du mouvement, ces pistes 11 présentent une forme générale incurvée dont le rayon de courbure est identique ou proche de la distance la séparant du centre de pivotement de la structure ferroviaire porteuse 6 comme représenté sur la figure 4.For reasons of simplification because the two lifting devices 1 and pivoting drive are identical, only one device will be described below. This device 1 is completed by a series of several carrying rollers and preferably coaches, for example two trains 7 and 8 of three rollers mounted on a platform 3 and 4 respectively and intended to receive, to resume and possibly but not necessarily to continue to do pivot the supporting railway structure 6 by its bottom as soon as its overhang towards the platform exceeds a certain limit, this in order to achieve good stability and security of the pivoting movements. The rollers of these trains 7 and 8 of rollers are housed in a recess in the structure of the quay as shown in FIG. 1 at a suitable distance from the edge of the quay. They protrude slightly from the surface of the quay to take up the bottom of the support structure in cantilever on the quay. These preferably motorized rollers are assemblies each formed by a rotating cylinder 9 of slightly frustoconical shape in order to benefit from the differences in circumferential speeds from one end to the other in order to avoid slipping. Their lateral surface is preferably covered with a metal tread 10 coming into contact with a bearing and rolling track 11 (Figure 4) specific to at least one end of the carrying railway structure 6 of the wagon. They comprise an electric motor unit 12 for driving the roller in rotation in the axis of the roller. As indicated, the load-bearing railway structures 6 have, at at least one of their ends on the underside, a planar bearing and rolling track 11, for example in the form of an attached plate or any other embodiment. Due to the pivoting nature of the movement, these tracks 11 have a generally curved shape whose radius of curvature is identical or close to the distance separating it from the pivot center of the carrying railway structure 6 as shown in FIG. 4.
Bien qu'une réalisation à deux dispositifs de levage et d'entraînement en pivotement ait été représentée, il faut considérer que l'invention se rapporte également à des réalisations à un seul dispositif, par exemple celles présentant un centre de pivotement en extrémité ou en un endroit décentré quelconque du wagon.Although an embodiment with two lifting and pivoting drive devices has been shown, it should be considered that the invention also relates to embodiments with a single device, for example those having a pivoting center at the end or at any off-center location on the car.
Dans ce cas, le dispositif combiné de levage et d'entraînement en pivotement est sensiblement identique ou équivalent à celui qui sera décrit ci- après et par conséquent une nouvelle description n'est pas nécessaire.In this case, the combined lifting and pivoting device is substantially identical or equivalent to that which will be described below and therefore a new description is not necessary.
De façon générale, le dispositif de levage et d'entraînement en pivotement selon l'invention se présente sous la forme d'un ensemble mécanique 13 monté sur la voie ferrée 2 entre les deux rails au niveau d'un emplacement réservé au chargement/déchargement appelé ci-après poste 5 de chargement/déchargement. Les parties inférieures de cet ensemble mécanique 13 sont logées dans une fosse adaptée de manière à rendre minimale la hauteur de la saillie que représente cet ensemble par rapport au sol. La partie logée dans le sol est de préférence protégée des intempéries et des agressions extérieures par une plaque de séparation.In general, the pivoting lifting and driving device according to the invention is in the form of a mechanical assembly 13 mounted on the railroad track 2 between the two rails at a location reserved for loading / unloading hereinafter called loading / unloading station 5. The lower parts of this mechanical assembly 13 are housed in a pit adapted so as to minimize the height of the projection that this assembly represents relative to the ground. The part housed in the floor is preferably protected from bad weather and external aggressions by a separation plate.
On peut également envisager de monter l'ensemble mécanique 13 sur un chariot mobile le long de la voie dans une tranchée entre les rails de la voie.One can also consider mounting the mechanical assembly 13 on a mobile carriage along the track in a trench between the rails of the track.
Une protection amovible contre les intempéries peut également être prévue pour la partie supérieure par exemple sous la forme d'un capot (non représenté) .Removable weather protection can also be provided for the upper part, for example in the form of a cover (not shown).
L'ensemble mécanique 13 du dispositif selon l'invention est monté en plus sur une plaque de base assurant l'assise mécanique et son montage sur la fosse ou sur un support de maintien entre les rails. Pour des raisons de simplification ces derniers moyens n'ont pas été représentés.The mechanical assembly 13 of the device according to the invention is additionally mounted on a base plate ensuring the mechanical seat and its mounting on the pit or on a holding support between the rails. For reasons of simplification, the latter means have not been shown.
L'ensemble mécanique 13 du dispositif 1 selon l'invention se compose d'une part d'un caisson pivotant 14 autour d'un axe horizontal 15. Le caisson pivotant 14 se divise en deux branches 16 et 17 ou plus portant chacune en extrémité une unité motorisée 18 et 19 formée de rouleaux motorisés 20 et 21 réunis entre eux par l'intermédiaire d'un élément tubulaire transversal commun 22. Chaque rouleau motorisé 20 ou 21 est porté également par un support basculant articulé 23 et 24. L'élément tubulaire transversal 22 traverse l'extrémité des branches 16 et 17 dans un fourreau supporté à encliquetage dans une pièce de réception 25 à entrée profilée en V. Chaque support articulé basculant 23 et 24 est relié à la tige motrice d'un vérin d'élévation respectivement 26 et 27 dont le corps est monté pivotant autour d'un axe 28 et 29 à palier déformable sur des supports annexes respectivement 30 et 31 formés par exemple de deux chapes parallèles telles que 32 et 33 leur conférant une possibilité d'absorber les écarts latéraux.The mechanical assembly 13 of the device 1 according to the invention consists on the one hand of a pivoting box 14 around a horizontal axis 15. The pivoting box 14 is divided into two branches 16 and 17 or more each carrying at the end a motorized unit 18 and 19 formed by motorized rollers 20 and 21 joined together by means of a common transverse tubular element 22. Each motorized roller 20 or 21 is also carried by an articulated tilting support 23 and 24. The element transverse tubular 22 passes through the end of the branches 16 and 17 in a supported sheath which snaps into a receiving part 25 with a V-shaped entry. Each articulated tilting support 23 and 24 is connected to the drive rod of an elevating cylinder 26 and 27 respectively, the body of which is pivotally mounted about an axis 28 and 29 with a deformable bearing on additional supports 30 and 31 respectively formed for example by two parallel yokes such as 32 and 33 giving them a possibility to absorb lateral deviations.
Ces vérins d'élévation 26 et 27 agissent chacun en poussée vers le haut sur les supports articulés portant les unités de rouleaux motorisés en vue de provoquer leur mouvement simultané d'élévation. Les rouleaux motorisés 20 et 21 sont du même type que ceux déjà décrits car formant les trains de rouleaux situés sur le quai. Ils sont constitués chacun d'un cylindre tournant 9 recouvert d'une bande métallique de roulement 10 de forme légèrement tronconique. Ils sont montés sur un axe longitudinal radial par rapport au centre de pivotement de la structure porteuse 6 autour duquel s'effectue la rotation sous l'effet d'un moteur d'entraînement électrique 12. Leur disposition est légèrement convergente vers le centre de pivotement de la structure porteuse 6 choisi central dans notre exemple. Cette disposition permet d'éviter le risque de ripage transversal lors du contact de levage et du mouvement d ' entraînement en pivotement de cette structure porteuse 6. Ces rouleaux motorisés 20 et 21 sont destinés à venir dans un premier temps en contact de poussée verticale avec la piste 11 d'appui et de roulement que présente en sous-face au moins une extrémité de la structure ferroviaire porteuse (figure 4) pour la lever sous l'effet des vérins d'élévation. Après élévation de la structure porteuse, leur mise en rotation provoque l'entraînement en pivotement de la structure ferroviaire porteuse par un roulage d'entraînement sur la piste d'appui et de roulement. Un mécanisme de rattrapage permet d'assurer aux rouleaux motorisés 20 et 21 un contact complet à plat avec la piste d'appui et de roulement 11. Ce mécanisme de rattrapage est représenté schématiquement par une succession de vues de profil illustrant le fonctionnement sur les figures 5 à 8.These elevation cylinders 26 and 27 act each pushed up on the articulated supports carrying the motorized roller units in order to cause their simultaneous lifting movement. The motorized rollers 20 and 21 are of the same type as those already described since they form the train of rollers located on the platform. They each consist of a rotating cylinder 9 covered with a metallic tread 10 of slightly frustoconical shape. They are mounted on a longitudinal longitudinal axis relative to the pivot center of the support structure 6 around which the rotation takes place under the effect of an electric drive motor 12. Their arrangement is slightly convergent towards the pivot center of the supporting structure 6 chosen central in our example. This arrangement makes it possible to avoid the risk of transverse shifting during the lifting contact and the pivoting drive movement of this support structure 6. These motorized rollers 20 and 21 are intended initially to come into vertical thrust contact with the support and rolling track 11 that is present on the underside of at least one end of the carrying railway structure (FIG. 4) in order to lift it under the effect of the lifting cylinders. After elevation of the supporting structure, their rotation causes the pivoting drive of the supporting railway structure by a driving roll on the bearing and rolling track. A take-up mechanism makes it possible to ensure that the motorized rollers 20 and 21 have complete flat contact with the bearing and rolling track 11. This take-up mechanism is represented diagrammatically by a succession of profile views illustrating the operation in the figures 5 to 8.
Pour éviter l'usure prématurée, il fallait assurer un dernier mouvement d'approche et un mouvement de levage selon une trajectoire verticale ou quasi verticale de façon à éviter les ripages entre chaque rouleau motorisé et la piste au moment du contact et pendant le levage. Pour ce faire, un exemple de solution est décrit ci-après. D'autres solutions équivalentes entrent dans le cadre de l'invention.To avoid premature wear, it was necessary to ensure a final approach movement and a movement lifting along a vertical or almost vertical trajectory so as to avoid skidding between each motorized roller and the track at the time of contact and during lifting. To do this, an example solution is described below. Other equivalent solutions are within the scope of the invention.
Selon cette variante, l'axe de pivotement 15 du caisson pivotant 14 est déplaçable par rapport à sa position de départ correspondant à la position escamotée horizontale de repos du caisson. Son déplacement permet d'obtenir une trajectoire approximativement verticale procurée par les vérins d'élévation pour l'extrémité du caisson et donc pour les rouleaux motorisés et ceci sur la portion de trajectoire correspondant à la phase finale d'approche et au levage.According to this variant, the pivot axis 15 of the pivoting box 14 is movable relative to its starting position corresponding to the horizontal retracted position of rest of the box. Its displacement makes it possible to obtain an approximately vertical trajectory provided by the elevation cylinders for the end of the box and therefore for the motorized rollers and this over the portion of trajectory corresponding to the final approach phase and to the lifting.
Les moyens envisagés sont les suivants.The means envisaged are as follows.
L'axe de pivotement 15 du caisson pivotant 14 est monté par exemple à chacune de ses extrémités sur deux biellettes elles mêmes basculantes autour d'un axe secondaire 34.The pivot axis 15 of the pivoting box 14 is mounted for example at each of its ends on two rods which are themselves tiltable around a secondary axis 34.
Lors de la course morte, c'est-à-dire pendant la poussée à vide des vérins d'élévation avant le contact des rouleaux motorisés avec la piste d'appui et de roulement, aucun effort important de poussée n'agit sur ceux-ci. Les vérins d'élévation élèvent simplement les rouleaux motorisés. Le caisson 14 pivote uniquement autour de son axe de pivotement 15 qui reste fixe par rapport à sa position d'origine (figures 6 et 7) .During the dead stroke, that is to say during the empty thrust of the lifting cylinders before the contact of the motorized rollers with the bearing and rolling track, no significant thrust force acts on them. this. The lifting cylinders simply raise the motorized rollers. The box 14 pivots only around its pivot axis 15 which remains fixed relative to its original position (Figures 6 and 7).
Cet axe de pivotement 15 étant mobile va se déplacer vers l'avant sous l'effet de la traction oblique par le caisson soumis à l'élévation par les vérins. L'arrangement décrit assure par le faible déplacement de l'axe de pivotement 15 du caisson 14 l'allongement nécessaire du bras de levier géométrique pour transformer l'arc circulaire de trajectoire en segment quasi rectiligne sur la partie finale de la trajectoire (figures 8 et 9) .This pivot axis 15 being movable will move forward under the effect of oblique traction by the box subjected to elevation by the jacks. The arrangement described ensures by the small displacement of the pivot axis 15 of the box 14 the necessary elongation of the geometric lever arm to transform the circular arc of trajectory into almost rectilinear segment on the final part of the trajectory (Figures 8 and 9).
On a décrit ci-dessus une forme de réalisation du dispositif dans laquelle les moyens de levage et les moyens de roulement sont combinés dans un même ensemble mécanique 13.An embodiment of the device has been described above in which the lifting means and the rolling means are combined in the same mechanical assembly 13.
Il convient de préciser que toutes les réalisations équivalentes dans lesquelles les moyens de levage et les moyens de roulement ne sont pas combinés, c'est-à-dire sont juxtaposés ou séparés, entrent dans le même concept inventif.It should be specified that all the equivalent embodiments in which the lifting means and the rolling means are not combined, that is to say are juxtaposed or separated, fall within the same inventive concept.
La combinaison des mouvements de levage et de roulement peut également intervenir. Dans tous ces cas, les réalisations correspondantes entrent dans le cadre de l'invention.The combination of lifting and rolling movements can also occur. In all these cases, the corresponding embodiments fall within the scope of the invention.
On peut ainsi adjoindre au caisson pivotant une fonction supplémentaire. Il peut comporter un moyen de soutien et de maintien en position de la plate-forme d ' extrémité correspondante du wagon pendant les opérations de chargement/déchargement . Une illustration de ce moyen est donnée par la figure 9 sur laquelle la face supérieure du caisson 14 comporte une structure réceptrice et de blocage 35 en V dans laquelle vient se loger à blocage l'extrémité 36 du retour 37 vers le bas du corps des plates-formes d'extrémité.It is thus possible to add an additional function to the pivoting box. It may include means for supporting and holding in position the corresponding end platform of the wagon during loading / unloading operations. An illustration of this means is given by FIG. 9 on which the upper face of the box 14 comprises a receiving and blocking structure 35 in V in which the end 36 of the return 37 is housed with blocking downwards the body of the plates - end shapes.
Le fonctionnement comporte les phases générales suivantes.Operation has the following general phases.
Le wagon de transport combiné rail/route est immobilisé avec une certaine tolérance à l'emplacement du poste 5 de chargement/déchargement en vue par exemple d'un chargement.The combined rail / road transport wagon is immobilized with a certain tolerance at the location of the loading / unloading station 5 for the purpose of loading, for example.
La position d'arrêt du wagon à l'emplacement prévu correspond aux positions des plates-formes d'extrémité qu'il faut sauvegarder dans le cas de l'immobilisation de celles-ci, chacune à partir d'un dispositif situé sur la voie. On actionne ces dispositifs s'il s'agit de dispositifs indépendants. Dans les autres cas envisagés, les positions relatives sont maintenues automatiquement par une liaison mécanique entre les plates-formes d'extrémité ou par une fonction annexe du ou des dispositif (s) de levage et de pivotement tel que celui décrit ci-dessus.The stop position of the wagon at the intended location corresponds to the positions of the end platforms which must be saved in the event of their immobilization, each from a device located on the track . These devices are activated if they are independent devices. In the other cases envisaged, the relative positions are automatically maintained by a mechanical connection between the end platforms or by an additional function of the lifting and pivoting device (s) such as that described above.
On procède donc à la mise en oeuvre du ou des dispositif (s) de levage et de pivotement. Les vérins d'élévation sont actionnés pour permettre le rapprochement des rouleaux motorisés 20 et 21 vers la piste d'appui et de roulement 11 correspondante de sous-face d'extrémité de la structure ferroviaire porteuse 6. Les rouleaux motorisés 20 et 21 se lèvent jusqu'à contact doux et à plat avec la piste d'appui et de roulement 11 par le jeu du mécanisme de rattrapage. Suivent alors, après le déverrouillage des liaisons d'assemblage dissociables entre la structure porteuse et les plates-formes d'extrémité, les mouvements de levage coordonnés des deux extrémités de la structure ferroviaire porteuse ou de la seule extrémité correspondante.We therefore proceed to the implementation of the device (s) for lifting and pivoting. The lifting cylinders are actuated to allow the motorized rollers 20 and 21 to be brought closer to the corresponding bearing and rolling track 11 of the end underside of the carrying railway structure 6. The motorized rollers 20 and 21 rise until soft and flat contact with the bearing and rolling track 11 by the play of the take-up mechanism. Then follow, after unlocking the separable assembly links between the supporting structure and the end platforms, the coordinated lifting movements of the two ends of the carrying railway structure or of the single corresponding end.
Le mouvement de levage se décompose en deux parties. La première concerne une fraction du déplacement correspondant à la détente des suspensions des plates-formes d'extrémité. La seconde concerne le levage proprement dit qui s'arrête peu après la dissociation des extrémités entre la structure porteuse 6 et les conformations de réception des plates-formes d'extrémité, l'élévation supplémentaire étant en générale faible car il n'existe pas d'obstacle au pivotement sur les plates-formes d'extrémité.The lifting movement is divided into two parts. The first concerns a fraction of the displacement corresponding to the relaxation of the suspensions of the end platforms. The second relates to the actual lifting which stops shortly after the separation of the ends between the supporting structure 6 and the receiving conformations of the end platforms, the additional elevation being generally small because there is no obstacle to pivoting on the end platforms.
Les rouleaux motorisés 20 et 21 sont ensuite actionnés en rotation par leur propres moteurs de manière à faire pivoter les extrémités de la structure porteuse pivotante du corps du wagon dans le même sens de pivotement jusqu'à la reprise des coins correspondants des extrémités de la structure porteuse 6 par les trains 7 et 8 des moyens motorisés de support-roulage sur le quai.The motorized rollers 20 and 21 are then actuated in rotation by their own motors so as to pivot the ends of the pivoting carrying structure of the wagon body in the same direction of pivoting until the corresponding corners of the ends of the structure are taken up again. carrier 6 by the trains 7 and 8 of the motorized means of rolling support on the quay.
Le pivotement s'effectue jusqu'à dégagement complet des extrémités de la structure ferroviaire porteuse de chaque plate-forme d'extrémité par un mouvement de pivotement d'amplitude suffisante pour le dégagement des extrémités de la structure ferroviaire porteuse et le positionnement oblique d'angle suffisant pour procurer une certaine aisance dans les manoeuvres de chargement/déchargement. Le chargement ou le déchargement peut alors avoir lieu. La charge routière accède à la structure ferroviaire porteuse par ses propres moyens, par exemple pour une semi-remorque par le tracteur qui la déplace. Les mouvements de fermeture du wagon s'effectuent dans le sens inverse. The pivoting takes place until the ends of the supporting rail structure of each end platform are completely cleared by a pivoting movement of sufficient amplitude to free the ends of the supporting rail structure and the oblique positioning of sufficient angle to provide some ease in loading / unloading maneuvers. Loading or unloading can then take place. The road load accesses the carrying railway structure by its own means, for example for a semi-trailer by the tractor which moves it. The closing movements of the wagon are carried out in the opposite direction.
