Abstract

A cradle-carrying wagon comprises a wagon chassis and at least one pivoting frame mounted about a pivot axis (O1) and possessing guides (24-27) for receiving at least one cradle. Means for locking the cradle to the chassis comprise a shaft fixed to the chassis and arranged along the vertical pivot axis, two fastening arms (40, 41) arranged on either side of the longitudinal plane of symmetry and mounted pivotably on this shaft between an unlocking configuration and a locking configuration, these arms possessing laterally projecting noses (46, 47) which are designed, in the locking configuration, each to engage between two substantially transverse flanks of a receptacle provided on the side members of the cradle and, in the unlocked configuration, to come out of these receptacles. Associated with these arms are means for controlling and guiding the movement of these arms (50-53, 60, 63) and means for blocking these arms in the locked configuration (50, 51). <IMAGE>

Description

L'invention concerne le verrouillage en position d'une charge équipée d'une berce, telle que benne, plate-forme, conteneur, ou analogue, sur un wagon équipé de cadres pivotants de chargement.The invention relates to the locking in position of a load equipped with a cradle, such as a bucket, platform, container, or the like, on a wagon equipped with pivoting loading frames.

Pour permettre le passage d'une charge équipée d'une berce entre un camion équipé d'un bras de chargement/déchargement et un wagon, il est connu de prévoir sur ce wagon un cadre rectangulaire horizontal relié à ce wagon par une articulation d'axe vertical situé dans le plan vertical longitudinal de symétrie du wagon et dans le plan vertical longitudinal de symétrie du cadre, à proximité de l'une des extrémités de ce cadre.To allow the passage of a load equipped with a cradle between a truck equipped with a loading / unloading arm and a wagon, it is known to provide on this wagon a horizontal rectangular frame connected to this wagon by an articulation of vertical axis situated in the longitudinal vertical plane of symmetry of the wagon and in the longitudinal vertical plane of symmetry of the frame, near one of the ends of this frame.

Pour le chargement/déchargement d'une berce sur ce wagon, on fait pivoter latéralement le cadre du côté où se trouve le camion jusqu'à aligner ce cadre avec le châssis du camion ; le transfert de la charge entre cadre et camion se fait alors par manoeuvre du bras de chargement/déchargement du camion.For the loading / unloading of a cradle on this wagon, the frame is pivoted laterally on the side where the truck is located until this frame is aligned with the chassis of the truck; the transfer of the load between frame and truck is then done by maneuvering the loading / unloading arm of the truck.

En cas de besoin, les moyens classiques sont mis en oeuvre pour assurer la compatibilité en hauteur du châssis du camion et du cadre.If necessary, conventional means are used to ensure compatibility in height of the chassis of the truck and the frame.

Il est à rappeler qu'une berce désigne les éléments d'interface nécessaires pour permettre le chargement/déchargement d'une charge à l'aide d'un bras de chargement/déchargement. Une berce comporte principalement deux longerons et, en une extrémité de ceux-ci, une extension verticale en haut de laquelle est prévu un barreau ou anneau de préhension adapté à venir en prise avec le crochet de préhension d'un bras de chargement/déchargement. A cette berce (on parle parfois de berce-squelette) est en pratique fixé par soudage, boulonnage ou analogue, le support de la charge proprement dite (plateau, caisse ...).It should be remembered that a cradle designates the interface elements necessary to allow the loading / unloading of a load using a loading / unloading arm. A cradle mainly comprises two beams and, at one end of them, a vertical extension at the top of which is provided a bar or gripping ring adapted to come into engagement with the gripping hook of a loading / unloading arm. In this cradle (sometimes referred to as skeleton cradle) is in practice fixed by welding, bolting or the like, the support of the actual load (tray, box ...).

Lorsqu'une berce est chargée sur un cadre pivotant à partir d'un camion, on ramène ce cadre dans l'alignement du wagon, et le problème qui se pose est alors de le verrouiller en position.When a cradle is loaded on a pivoting frame from a truck, this frame is brought back into alignment with the wagon, and the problem that arises is then to lock it in position.

Il a été prévu à cet effet, de fixer aux extrémités des longerons du cadre, près desquelles est montée l'articulation, des butées en U adaptées à recevoir en butée des galets arrière montés classiquement aux extrémités arrière des longerons de berce ; ces butées sont adaptées à résister à des efforts parasites longitudinaux ou verticaux dirigés vers le haut. Lorsque le cadre est amené dans l'alignement du wagon, les extrémités avant des longerons de berce (auxquelles est fixée l'extension verticale précitée) viennent en regard d'élements de butée solidaires du wagon. Dans une première version, ces éléments de butée sont des butoirs fixes adaptés à résister à tout glissement longitudinal de la berce dans leur direction, sans aucune possibilité de retenue en cas d'efforts parasites de soulèvement. Dans une seconde version, ces éléments de butée comportent des crochets venant en prise avec des saillies latérales prévues à l'avant de la berce adaptés à résister à des efforts parasites longitudinaux ou de soulèvement vers le haut.To this end, provision has been made to fix the ends of the frame rails, near which the joint is mounted, U-shaped stops adapted to receive in abutment rear rollers conventionally mounted at the rear ends of the cradle rails; these stops are adapted to withstand longitudinal or vertical parasitic forces directed upwards. When the frame is brought into alignment with the wagon, the front ends of the cradle rails (to which the above-mentioned vertical extension is fixed) come opposite abutment elements integral with the wagon. In a first version, these abutment elements are fixed buffers adapted to resist any longitudinal sliding of the cradle in their direction, without any possibility of restraint in the event of parasitic lifting efforts. In a second version, these abutment elements include hooks engaging with lateral projections provided at the front of the cradle adapted to withstand longitudinal parasitic forces or upward lifting.

Il est rappelé que les normes françaises et européennes de sécurité exigent généralement que les diverses butées précitées résistent, en cas de tamponnements parasites, à des accélérations pouvant aller jusqu'à 4 g.It is recalled that French and European safety standards generally require that the various abovementioned stops resist, in the event of parasitic buffering, accelerations of up to 4 g.

Malgré leurs mérites, les solutions précitées ont divers inconvénients, dont notamment les suivants :

  • lorsque des chocs en butée sont appliqués aux butées en U prévues sur les longerons du cadre, c'est par l'intermédiaire de ce cadre que transitent tous les efforts parasites, avec risques de détérioration du cadre et de l'articulation cadre/wagon ;
  • ces ensembles de butées ne sont valables que pour une seule longueur de berce, ce qui impose de prévoir des wagons pour chaque type de berce ;
  • il n'est pas possible de charger des berces sur les cadres par au-dessus.
Despite their merits, the aforementioned solutions have various drawbacks, including in particular the following:
  • when abutment shocks are applied to the U-shaped stops provided on the frame rails, it is through this frame that all parasitic forces pass, with risks of deterioration of the frame and of the frame / wagon articulation;
  • these sets of stops are only valid for a single cradle length, which requires the provision of wagons for each type of cradle;
  • it is not possible to load cradles on the frames from above.

L'invention a pour objet de pallier les inconvénients précités en permettant le maintien, sur le cadre d'un wagon, de berces de différentes longueurs, avec la reprise directement par le wagon des efforts parasités longitudinaux (dans les deux sens) et de soulèvement qui peuvent être appliqués involontairement aux berces (ou à la charge dont elles sont solidaires), tout en autorisant un chargement par au-dessus de ces berces, sans pour autant nécessiter de modifications sensibles de la géométrie normalisée des berces, avec possibilité d'adaptation des berces existantes.The object of the invention is to overcome the aforementioned drawbacks by allowing the holding of rockers of different lengths on the frame of a wagon, with the parasitic longitudinal (in both directions) and lifting forces being taken up directly by the wagon which can be applied involuntarily to the cradles (or to the load of which they are integral), while authorizing a loading by above these cradles, without requiring significant modifications of the standard geometry of the cradles, with possibility of adaptation existing cradles.

L'invention propose à cet effet un wagon porte-berce, comportant un châssis de wagon adapté à rouler sur des rails et au moins un cadre pivotant sensiblement horizontal monté pivotant par rapport à ce châssis autour d'un axe vertical de pivotement de part et d'autre d'un plan longitudinal de symétrie du châssis, ce cadre pivotant comportant des guides de réception d'au moins une berce comportant des longerons, caractérisé en ce qu'il comporte des moyens de verrouillage de la berce au châssis comportant un arbre solidaire du châssis et disposé selon l'axe vertical de pivotement, deux bras d'accrochage disposés de part et d'autre du plan longitudinal de symétrie et montés pivotants sur cet arbre entre une configuration de déverrouillage et une configuration de verrouillage, ces bras comportant des becs latéralement en saillie adaptés, dans la configuration de verrouillage, à s'engager chacun entre deux flancs sensiblement transversaux d'un logement prévu sur les longerons de la berce et, dans la configuration déverrouillée à sortir de ces logements, ainsi que des moyens de commande et de guidage en mouvement de ces bras et des moyens de blocage de ces bras en configuration verrouillée.To this end, the invention proposes a cradle-carrying wagon, comprising a wagon chassis adapted to roll on rails and at least one substantially horizontal pivoting frame pivotally mounted relative to this chassis around a vertical pivot axis on the side and on the other side of a longitudinal plane of symmetry of the chassis, this pivoting frame comprising guides for receiving at least one cradle comprising side members, characterized in that it comprises means for locking the cradle to the chassis comprising a shaft integral with the chassis and arranged along the vertical pivot axis, two attachment arms arranged on either side of the longitudinal plane of symmetry and pivotally mounted on this shaft between a configuration of unlocking and a locking configuration, these arms comprising laterally projecting nozzles adapted, in the locking configuration, to each engage between two substantially transverse sides of a housing provided on the side members of the cradle and, in the unlocked configuration out of these housings, as well as means for controlling and guiding the movement of these arms and means for blocking these arms in the locked configuration.

Les figures 1 à 3 représentent un wagon ferroviaire 1 muni de trois cadres pivotants 2 adaptés chacun à recevoir une berce de longueur égale ou inférieure à la longueur des cadres. Il y a ici trois cadres par wagon mais ce nombre peut bien sûr être modifié (deux, voire quatre ...).Figures 1 to 3 show a railway wagon 1 provided with three pivoting frames 2 each adapted to receive a cradle of length equal to or less than the length of the frames. There are three frames here per wagon but this number can of course be modified (two, even four ...).

Le wagon a ici une longueur de 18,66 m et chaque cadre a une longueur de 5,70 m.The wagon here has a length of 18.66 m and each frame has a length of 5.70 m.

Chaque cadre est relié au châssis du wagon par une articulation d'axe 01, 02 ou 03 vertical, situé dans un plan longitudinal de symétrie du wagon et dans un plan longitudinal de symétrie du cadre, à proximité d'une extrémité du cadre (ici à 1,94 m de celle-ci).Each frame is connected to the chassis of the wagon by a hinge of axis 0 1 , 0 2 or 0 3 vertical, located in a longitudinal plane of symmetry of the wagon and in a longitudinal plane of symmetry of the frame, near one end of the frame (here at 1.94 m from it).

A la figure 1, l'un des cadres est incliné latéralement de 45° en sorte d'être dans l'alignement, au moins en vue de dessus, du châssis 3 d'un camion 4 muni d'un bras de chargement/déchargement de tout type connu approprié (non représenté), par exemple du type décrit dans le brevet FR-2.185.520 de la Demanderesse.In FIG. 1, one of the frames is inclined laterally by 45 ° so as to be in alignment, at least in top view, of the chassis 3 of a truck 4 provided with a loading / unloading arm of any suitable known type (not shown), for example of the type described in patent FR-2,185,520 of the Applicant.

A la figure 2, c'est le cadre longitudinalement opposé qui est incliné de 45° du côté opposé, de sorte que les figures 1 et 2 peuvent aussi être interprétées comme représentant deux wagons similaires sur deux voies adjacentes et en cours de chargement simultané.In FIG. 2, it is the longitudinally opposite frame which is inclined by 45 ° on the opposite side, so that FIGS. 1 and 2 can also be interpreted as representing two similar wagons on two adjacent tracks and during simultaneous loading.

Sur la figure 3 où les cadres ont été enlevés, le wagon 1 comporte deux longerons centraux 3 et 4, deux longerons latéraux 5 et 6, des traverses de liaison dont des traverses d'extrémité 7 et 8, des tampons 9, des roues non représentées adaptées à rouler sur des rails 10, et trois platelages identiques 11, 12 et 13, dont l'un, repéré 11 est représenté en détail à la figure 4. Ces platelages sont solidaires des longerons 3-6.In Figure 3 where the frames have been removed, the wagon 1 has two central beams 3 and 4, two side beams 5 and 6, connecting crosspieces including end crosspieces 7 and 8, buffers 9, wheels not shown suitable for running on rails 10, and three identical decks 11, 12 and 13, one of which, marked 11 is shown in detail in Figure 4. These decks are integral with the side members 3-6.

Le platelage 11 comporte quatre plaques : une plaque transversale centrale 14 destinée à recevoir pour fixation une couronne de roulement non représentée, à l'aide de perçages 15 disposés en un anneau, une plaque interne de roulement 16, une plaque externe de roulement 17 et une plaque extrême 18.The deck 11 has four plates: a central transverse plate 14 intended to receive for fixing a bearing crown not shown, by means of holes 15 arranged in a ring, an internal bearing plate 16, an external bearing plate 17 and an extreme plate 18.

Sur la plaque centrale 14 sont fixés des pions 19 en saillie vers le haut prévus pour borner le débattement en rotation du cadre destiné à être monté sur ce platelage ; sur la plaque interne de roulement sont fixés deux barreaux arqués 20 en saillie vers le haut centrés sur l'axe 01, dont le rôle apparaîtra plus loin, destinés au guidage d'un doigt vertical dont les petits cercles blancs et noirs visualisant diverses positions possibles ; sur la plaque extrême 18 sont fixés des plaques verticales 21 et des organes auxiliaires de butée 22 dont le rôle apparaîtra également plus loin.On the central plate 14 are fixed pins 19 projecting upwardly intended to limit the rotational movement of the frame intended to be mounted on this decking; on the internal rolling plate are fixed two arched bars 20 projecting upwards centered on the axis 0 1 , the role of which will appear below, intended for guiding a vertical finger whose small white and black circles visualizing various positions possible; on the end plate 18 are fixed vertical plates 21 and auxiliary stop members 22 whose role will also appear below.

La figure 5 représente le platelage de la figure 4 sur lequel est monté le cadre 11 et les moyens de verrouillage prévus par l'invention.Figure 5 shows the deck of Figure 4 on which is mounted the frame 11 and the locking means provided by the invention.

Le cadre 11 comporte principalement deux longerons 24 et 25 longés intérieurement, chacun, par une piste de roulement 26 ou 27 destinée à recevoir les galets arrière d'une berce 100 à charger et à soutenir les longerons 101 de celle-ci (voir la figure 8). Ces longerons sont raccordés notamment par deux traverses 28 et 29 munis chacune de galets de roulement 30 et 31 disposés de part et d'autre de l'axe d'articulation 01 et destinés à rouler sur les plaques de roulement 16 et 17. En outre, ce cadre comporte une plaque 32 fixée aux longerons et à l'une des pistes d'un grand palier 33 en couronne, par exemple à billes, fixé par son autre piste à la plaque 14 à la faveur des perçages 15.The frame 11 mainly comprises two beams 24 and 25 internally lengthened, each by a rolling track 26 or 27 intended to receive the rear rollers of a cradle 100 to be loaded and to support the beams 101 thereof (see figure 8). These beams are connected in particular by two crosspieces 28 and 29 each provided with rollers 30 and 31 arranged on either side of the articulation axis 0 1 and intended to roll on the rolling plates 16 and 17. In furthermore, this frame comprises a plate 32 fixed to the side members and to one of the tracks of a large bearing 33 in a crown, for example with balls, fixed by its other track to the plate 14 by means of the holes 15.

Cette plaque 32 présente un perçage 34 d'axe confondu avec 01 et traverse par un arbre 35 solidaire de la plaque 14 à laquelle il est en outre fixé par des goussets de rigidification 36 (voir la figure 7). Cet arbre présente un épaulement 37, au dessus du niveau de la plaque 32, en sorte de former un tronçon rétréci 38 sur lequel sont emmanchées les extrémités percées de deux bras de verrouillage 40 et 41. Ces extrémités sont maintenues engagées sur ce tronçon rétréci 38 par une bague 42 fixée par une broche transversale 43 (non représentée aux figures 5 et 6). Ces bras 40 et 41 sont plats et bordés intérieurement et extérieurement par des rebords de rigidification (dont seuls les rebords externes 44 et 45 sont visibles à la figure 7).This plate 32 has a bore 34 with an axis coinciding with 0 1 and passes through a shaft 35 integral with the plate 14 to which it is further fixed by stiffening gussets 36 (see Figure 7). This shaft has a shoulder 37, above the level of the plate 32, so as to form a narrowed section 38 on which are fitted the drilled ends of two locking arms 40 and 41. These ends are kept engaged on this narrowed section 38 by a ring 42 fixed by a transverse pin 43 (not shown in Figures 5 and 6). These arms 40 and 41 are flat and bordered internally and externally by stiffening flanges (of which only the external flanges 44 and 45 are visible in FIG. 7).

Ces bras s'étendent vers le platelage extrême 18 et se terminent par des crochets ou becs 46 et 47 orientés horizontalement à l'opposé l'un de l'autre.These arms extend towards the end deck 18 and end with hooks or spouts 46 and 47 oriented horizontally opposite one another.

Ces bras admettent un débattement en rotation autour de l'arbre 35 (ou de 01) entre la configuration écartée de la figure 5 et la configuration rapprochée de la figure 6. Dans la configuration écartée, les crochets empiètent dans le volume balayé par les longerons d'une berce chargée (voir la figure 8) : c'est une configuration de verrouillage, tandis qu'ils sont à l'écart de celui-ci dans la configuration rapprochée, qui est une configuration de déverrouillage.These arms admit a movement in rotation around the shaft 35 (or 0 1 ) between the discarded configuration of FIG. 5 and the close configuration of FIG. 6. In the discarded configuration, the hooks encroach on the volume swept by the side members of a loaded cradle (see Figure 8): this is a locking configuration, while they are away from it in the close configuration, which is an unlocking configuration.

Pour la commande de leurs positions ces bras sont articulés, à proximité de leurs becs ou crochets, par des biellettes 50 et 51 par ailleurs articulées sur un même coulisseau 52 monté coulissant sur une barre de guidage 53 solidaire du cadre, ici solidaire de la traverse 28. Ces biellettes sont articulées autour d'axes verticaux, au moyen de pions 54 à 57 représentés à la figure 8.For the control of their positions, these arms are articulated, close to their beaks or hooks, by connecting rods 50 and 51 moreover articulated on the same slide 52 mounted sliding on a guide bar 53 secured to the frame, here secured to the cross member 28. These rods are articulated around vertical axes, by means of pins 54 to 57 shown in FIG. 8.

Sous le coulisseau 52 vient en saillie un pion ou doigt de guidage 60 engagé avec jeu entre deux portées de guidage 61 et 62 en regard, qui sont les tranches en regard des éléments arqués 20 de la figure 4.Under the slide 52 projects a guide pin or pin 60 engaged with clearance between two guide bearing surfaces 61 and 62 facing each other, which are the facing sections of the arcuate elements 20 of FIG. 4.

Sur ce pion de guidage est engagé un levier 63 dont les extrémités 64 et 65 dépassent latéralement du cadre (voir les figures 5, 6 et 8) et sont munies de poignées de manutention 66 et 67. Ce levier est retenu à la partie supérieure du pion de guidage 60 par une broche 68 sur laquelle appuie une rondelle de retenue 69.On this guide pin is engaged a lever 63 whose ends 64 and 65 project laterally from the frame (see FIGS. 5, 6 and 8) and are provided with handling handles 66 and 67. This lever is retained at the upper part of the guide pin 60 by a pin 68 on which a retaining washer 69 is supported.

Ainsi que cela ressort clairement des figures 6, 8 et 10, les bras comportent sous les crochets des crochets verticaux de retenue au décollement 70 et 71 adaptés à venir en prise sous les pistes de roulement 26 et 27 du cadre.As is clear from FIGS. 6, 8 and 10, the arms comprise vertical hooks for detaching the detachment 70 and 71 under the hooks adapted to come into engagement under the rolling tracks 26 and 27 of the frame.

Les extrémités 64 et 65 du levier 63 sont engagées dans des fentes horizontales 81 de plaques verticales 80 soudées aux longerons du cadre et dont le détail est donné aux figures 11 à 13.The ends 64 and 65 of the lever 63 are engaged in horizontal slots 81 of vertical plates 80 welded to the side members of the frame and the details of which are given in FIGS. 11 to 13.

Sur chaque plaque 80 sont montés, auprès des extrémités de la fente 81, des crochets 82 et 83 orientés l'un vers l'autre, munis de poignées de préhension 84 et dont les becs 85 sont adaptés à forcer le soulèvement des crochets lorsque l'extrémité correspondante du levier est amenée vers l'une des extrémités de la fente, et à l'y maintenir ensuite.On each plate 80 are mounted, near the ends of the slot 81, hooks 82 and 83 oriented towards each other, provided with gripping handles 84 and whose beaks 85 are adapted to force the lifting of the hooks when the the corresponding end of the lever is brought to one of the ends of the slot, and then to hold it there.

Ces plaques 80 sont positionnées sur les longerons du cadre de manière à ce que les extrémités du levier soient toutes aux extrémités (dites extrémités internes ou de fermeture) des fentes 81 les plus proches de la plaque 32 liée à la couronne-palier dans la configuration de la figure 5, et les fentes ont une longueur telle que, lorsque l'une des extrémités du levier reste en place tandis que l'autre extrémité du levier parcourt la fente dans laquelle elle est engagée jusqu'à l'autre extrémité de la fente (extrémité d'ouverture) le coulisseau et les bras de verrouillage viennent dans la configuration de la figure 6.These plates 80 are positioned on the side members of the frame so that the ends of the lever are all at the ends (said internal or closing ends) of the slots 81 closest to the plate 32 linked to the bearing-bearing in the configuration of FIG. 5, and the slots have a length such that, when one of the ends of the lever remains in place while the other end of the lever traverses the slot in which it is engaged up to the other end of the slot (opening end) the slide and the locking arms come in the configuration of figure 6.

Dans cette configuration de la figure 6, le pion de guidage 60 est retenu latéralement par les portées de guidage 61 et 62 des éléments arqués 20 de la figure 4 : aucune rotation du cadre autour de l'axe 0 n'est possible. Cela évite, à des fins de sécurité, que le cadre puisse être manoeuvré lorsqu'une berce y est posée sans être verrouillée au wagon.In this configuration of FIG. 6, the guide pin 60 is retained laterally by the guide surfaces 61 and 62 of the arched elements 20 of FIG. 4: no rotation of the frame around the axis 0 is possible. This prevents, for safety purposes, that the frame can be maneuvered when a cradle is placed there without being locked to the wagon.

De manière préférée, le coulisseau 52 est dans la configuration de la figure 6, en butée contre la traverse 28 du cadre. Cela permet de contrôler le verrouillage d'une berce comme suit : si d'un côté du wagon (sans voir la position générale du levier) le levier est dans l'extrémité de fermeture de la fente et si on peut amener cette extrémité dans l'autre extrémité d'ouverture, c'est que l'autre extrémité du levier était en configuration de fermeture, et que les moyens de verrouillage (bras ...) étaient à l'origine en configuration de verrouillage ; un tel mouvement de l'extrémité gauche du levier de la figure 6 ne serait en effet pas possible.Preferably, the slide 52 is in the configuration of FIG. 6, in abutment against the cross member 28 of the frame. This allows the locking of a cradle to be checked as follows: if on one side of the wagon (without seeing the general position of the lever) the lever is in the closing end of the slot and if this end can be brought into the Another opening end is that the other end of the lever was in the closed configuration, and that the locking means (arms, etc.) were originally in the locked configuration; such a movement of the left end of the lever of Figure 6 would indeed not be possible.

Dans la configuration de la figure 5, le pion de guidage 62 sort de la rainure entre les portées 60 et 61 ce qui permet le pivotement du cadre. Lors de ce pivotement, les flancs concaves 86 et 87 des éléments arqués 20 de la figure 4 interdisent tout déverrouillage et ce n'est que lorsque le pion de guidage a cessé de longer ces éléments que le déverrouillage devient à nouveau possible (voir les traces successives de ce pion de guidage à la figure 4 où les cercles blancs correspondent à des positions de déverrouillage et les cercles noirs à des positions de verrouillage).In the configuration of Figure 5, the guide pin 62 comes out of the groove between the surfaces 60 and 61 which allows the frame to pivot. During this pivoting, the concave sides 86 and 87 of the arched elements 20 of FIG. 4 prohibit any unlocking and it is only when the guide pin has ceased to run alongside these elements that unlocking becomes possible again (see the traces successive of this guide pin in Figure 4 where the white circles correspond to unlocking positions and the black circles to locking positions).

En configuration de verrouillage, les crochets 46 et 47 pénètrent dans des logements ménagés dans les longerons de la berce 100.In the locking configuration, the hooks 46 and 47 penetrate into housings formed in the side members of the cradle 100.

Les figures 14 et 15 représentent un bloc 90 adapté à être fixé dans l'un, droit (voir figure 10), des longerons de ce cadre (ces longerons sont classiquement des profilés en C dont les concavités se font face) ; un bloc symétrique est à fixer dans le longeron gauche.Figures 14 and 15 show a block 90 adapted to be fixed in one, straight (see Figure 10), side members of this frame (these side members are conventionally C profiles whose concavities face each other); a symmetrical block is to be fixed in the left side member.

Ce bloc comporte un logement 91 comportant un flanc transversal 92 adapté à être longé par le bord interne 46A, 47A, du crochet correspondant, et un flanc 93 incliné à 60° adapté à être longé par le bord externe 46B, 47B, de ce crochet.This block comprises a housing 91 comprising a transverse flank 92 adapted to be bordered by the edge internal 46A, 47A, of the corresponding hook, and a side 93 inclined at 60 ° adapted to be bordered by the external edge 46B, 47B, of this hook.

Il est à noter à ce propos que le bord externe des crochets est sensiblement transversal à une ligne le reliant à l'axe 01, de manière à lui permettre de pénétrer avec faible jeu dans les logements 91, de manière à ce que chaque crochet vienne sensiblement occuper toute la section de son logement (à un jeu approprié près), avec ses bords en regard des flancs du logement.It should be noted in this regard that the outer edge of the hooks is substantially transverse to a line connecting it to the axis 0 1 , so as to allow it to penetrate with little play in the housings 91, so that each hook comes substantially occupy the entire section of its housing (with an appropriate clearance), with its edges facing the sides of the housing.

On appréciera qu'ainsi, en configuration de verrouillage, les bras de verrouillage reprennent (après éventuel rattrapage du jeu précité) tous les efforts longitudinaux parasites qui peuvent être appliqués à la berce, dans les deux sens, ainsi que d'éventuels efforts de soulèvement grâce aux becs verticaux 70 et 71, et ce quelle que soit la longueur de la berce considérée du moment que les logements sont prévus au bon endroit.It will be appreciated that thus, in the locking configuration, the locking arms take up (after possible compensation for the aforementioned clearance) all the parasitic longitudinal forces which can be applied to the cradle, in both directions, as well as possible lifting forces. thanks to the vertical nozzles 70 and 71, regardless of the length of the cradle considered as long as the housings are provided in the right place.

Il est à noter à ce propos que, dans la configuration de verrouillage de la figure 5, les biellettes sont sensiblement dans le prolongement l'une de l'autre ce qui évite, par arc-boutement de ces biellettes, que les crochets ou becs ne se rapprochent lors de ces efforts parasites. Cette disposition n'est toutefois pas indispensable.It should be noted in this connection that, in the locking configuration of FIG. 5, the links are substantially in the extension of one another, which avoids, by bracing these links, that the hooks or spouts do not approach during these parasitic forces. However, this provision is not essential.

Il est important de noter que cette reprise des efforts se fait par des éléments (ces bras) directement attelés au wagon, sans solliciter le cadre lui-même, sans risque en particulier pour la couronne-palier de liaison du cadre au wagon.It is important to note that this recovery of forces is done by elements (these arms) directly coupled to the wagon, without stressing the frame itself, without risk in particular for the crown-bearing connecting the frame to the wagon.

La figure 16 présente une variante de la figure 4 dans laquelle les éléments arqués 20 sont remplacés par un bloc arqué unique 20′ dans lequel est ménagée une rainure arquée 20′A (tous les éléments du platelage étant par ailleurs identiques). Cette rainure, dans laquelle pénètre le pion de guidage 60, assure un déverrouillage automatique d'une berce chargée au fur et à mesure qu'on s'éloigne, pour le cadre, d'une configuration alignée avec le wagon (petit cercle noir) vers une configuration pivotée de chargement/déchargement (petits cercles blancs). Le levier 63 peut alors être supprimé.FIG. 16 presents a variant of FIG. 4 in which the arcuate elements 20 are replaced by a single arcuate block 20 ′ in which an arcuate groove 20′A is formed (all the elements of the decking being otherwise identical). This groove, into which the guide pin 60 penetrates, ensures an unlocking automatic of a loaded cradle as one moves away, for the frame, from a configuration aligned with the wagon (small black circle) towards a pivoted configuration of loading / unloading (small white circles). The lever 63 can then be removed.

Les figures 17 à 19 montrent en détail les organes auxiliaires de butée 22 représentés aux figures 4 ou 16.FIGS. 17 to 19 show in detail the auxiliary stop members 22 shown in FIGS. 4 or 16.

Chaque organe auxiliaire 22 comporte un manchon 94 solidaire du platelage 18 dans lequel est engagée une tige 95 aux extrémités de laquelle sont fixées une tige de manoeuvre et une patte allongée transversale 97. Sur la tige de manoeuvre, est fixée une plaquette 98 longeant un prolongement 99 du manchon. Un ressort 94 A disposé dans le manchon autour de la tige tend à pousser axialement cette tige en sorte d'écarter la patte vis à vis du manchon.Each auxiliary member 22 comprises a sleeve 94 integral with the deck 18 in which is engaged a rod 95 at the ends of which are fixed an operating rod and an elongated transverse tab 97. On the operating rod, a plate 98 is fixed along an extension 99 of the sleeve. A spring 94 A disposed in the sleeve around the rod tends to push this rod axially so as to separate the tab from the sleeve.

Dans la configuration de repos représentée aux figures 17 à 19 la patte 97 a son écartement maximal vis à vis du manchon et longe la plaque 18.In the rest configuration shown in FIGS. 17 to 19, the tab 97 has its maximum spacing with respect to the sleeve and runs along the plate 18.

Cette patte et cette poignée de manoeuvre sont tournées latéralement vers l'extérieur du wagon.This tab and this operating handle are turned laterally towards the outside of the wagon.

Ainsi qu'il ressort de la figure 5 les organes auxiliaires 22 sont disposés en sorte que les pattes 97 encadrent latéralement les extrémités des longerons et en empêchent ainsi toute rotation.As is apparent from Figure 5 the auxiliary members 22 are arranged so that the legs 97 laterally frame the ends of the side members and thus prevent any rotation.

Pour permettre la rotation du cadre d'un côté du wagon il suffit de tirer sur la tige de manoeuvre de l'organe 22 situé dudit côté de manière à rapprocher la patte du manchon, libérant ainsi le longeron situé du même côté. On redresse sur quelques dizaines de degrés la tige de manoeuvre en mettant en appui la plaquette 98 contre le prolongement 99. Dès le début de sa rotation vers le côté, ce longeron, grâce à une plaquette 110 horizontale fixée à son extrémité à un niveau supérieur à la hauteur du manchon 94, provoque automatiquement, par effet de came sur la patte redressée, un rabattement de celle-ci à l'horizontale et un retour de l'organe auxiliaire dans sa position de repos dans laquelle il sera à nouveau à même de bloquer en rotation le cadre lorsqu'il reviendra dans sa position d'alignement avec le wagon.To allow the rotation of the frame on one side of the wagon, it suffices to pull on the operating rod of the member 22 located on said side so as to bring the tab of the sleeve closer, thereby releasing the spar located on the same side. The operating rod is straightened over a few tens of degrees by pressing the plate 98 against the extension 99. From the start of its rotation to the side, this spar, thanks to a horizontal plate 110 fixed at its end at a higher level at the height of the sleeve 94, automatically causes, by the effect of the cam on the straightened tab, its folding down to the horizontal and a return of the auxiliary member to its rest position in which it will again be able to lock the frame in rotation when it returns to its position of alignment with the wagon.

Ces organes auxiliaires 22 sont donc des organes de verrouillage en rotation du cadre.These auxiliary members 22 are therefore members for locking the frame in rotation.

Quant aux éléments 21, ce sont des plaques verticales munies de chanfreins et destinées à servir de support pour les extrémités en porte-à-faux des longerons en configuration d'alignement du cadre avec le wagon.As for the elements 21, these are vertical plates provided with chamfers and intended to serve as support for the cantilever ends of the side members in configuration for alignment of the frame with the wagon.
