Description

L'invention concerne un engin poseur de ponts du type comportant au moins une travure disposée sur un châssis et des organes adaptés pour déposer le pont à l'avant de l'engin.The invention relates to a bridge-laying machine of the type comprising at least one span arranged on a chassis and members adapted to deposit the bridge at the front of the machine.

On connait de nombreux types d'engins poseurs de ponts. Un premier type d'engin est adapté pour le lancement de ponts "ciseaux" dont la portée est de l'ordre d'une vingtaine de mètres. Les travures sont transportées en deux tronçons repliés l'un sur l'autre autour d'une articulation centrale, et sont déployées en décrivant une rotation. Ce mode de mise en oeuvre présente un inconvénient majeur du fait que lors de la rotation, les travures atteignent une hauteur importante. En effet, le pont ne peut être déployé qu'en terrain dégagé à cause de la hauteur libre nécessaire. De plus, cette rotation augmente les risques de vulnérabilité.Many types of bridge-laying machines are known. A first type of machine is suitable for launching "scissor" bridges whose range is of the order of twenty meters. The spans are transported in two sections folded one on the other around a central articulation, and are deployed by describing a rotation. This mode of implementation has a major drawback in that during the rotation, the spans reach a significant height. Indeed, the bridge can only be deployed in open ground because of the necessary headroom. In addition, this rotation increases the risks of vulnerability.

Pour pallier ces inconvénients, d'autres engins mettent en oeuvre des ponts transportés en un tronçon, ou en plusieurs tronçons superposés que l'on verrouille bout à bout après un déplacement relatif desdits tronçons visant à les aligner sensiblement dans un même plan. Selon ce principe, plusieurs techniques sont utilisées pour déposer les travures ainsi assemblées.To overcome these drawbacks, other vehicles use bridges transported in one section, or in several superposed sections which are locked end to end after a relative movement of said sections aimed at aligning them substantially in the same plane. According to this principle, several techniques are used to deposit the spans thus assembled.

Une première technique, notamment décrite dans FR-A-2.477.599, FR-A-2.577.953 et FR-A-2.577.863, consiste à utiliser un bras manipulateur extensible venant prendre appui par son extrémité libre sur la berge à atteindre et sur lequel le pont est amené à coulisser. Cette technique permet de résoudre les problèmes d'équilibre de l'engin lors de la phase de dépose. Toutefois elle présente l'inconvénient majeur de réquérir un bras de même longueur que le pont, par conséquent lourd et encombrant, ce qui va à l'encontre des objectifs de mobilité et d'ergonomie généralement recherchés.A first technique, in particular described in FR-A-2,477,599, FR-A-2,577,953 and FR-A-2,577,863, consists in using an extendable manipulator arm coming to bear by its free end on the bank to be reached and on which the bridge is made to slide. This technique makes it possible to solve the problems of balance of the machine during the removal phase. However, it has the major drawback of requiring an arm the same length as the bridge, which is therefore heavy and bulky, which goes against the objectives of mobility and ergonomics generally sought after.

Une autre technique consiste à utiliser un engin conçu de façon à lancer le pont par l'arrière après avoir recherché un point d'appui convenable. Toutefois cette solution présente un inconvénient majeur car elle nécéssite la présence de personnel hors de l'engin du fait de l'éloignement et de l'orientation de la cabine. Celle-ci est en effet disposée sur l'extrémité de l'engin la plus éloignée de la coupure de terrain à franchir et le pilote a donc la vue masquée par le pont et l'engin. Sans aide exterieure il lui est ainsi impossible d'assurer la manoeuvre. Cette disposition rend donc très problématique l'utilisation d'un tel engin dans un environnement hostile.Another technique consists in using a machine designed so as to launch the bridge from the rear after having sought a suitable point of support. However, this solution has a major drawback because it requires the presence of personnel outside the machine due to the distance and orientation of the cabin. This is in fact placed on the end of the craft furthest from the cut in terrain to be crossed and the pilot therefore has the view masked by the bridge and the craft. Without outside help it is thus impossible for him to ensure the maneuver. This provision therefore makes it very problematic to use such a device in a hostile environment.

Une troisième technique notamment décrite en variante dans FR-A-1.553.517 consiste à utiliser un bras de longueur fixe et limitée sur lequel le pont est amené à coulisser. Ce bras est dans un premier temps soumis à une rotation de façon à incliner le pont et permettre la dépose de son extrémité avant sur la berge opposée de la brèche. Il comporte de plus un tronçon avant articulé permettant, sous l'effet d'un vérin, de déposer l'extrémité arrière du pont sur la berge où se trouve l'engin. Cette technique permet de pallier partiellement les inconvénients des deux premières techniques ci-dessus décrites. Toutefois, la rotation du bras se fait au détriment du volume habitable de la cabine et pose des problèmes d'ergonomie. De plus, le bras doit être doté d'un tronçon articulé pour la dépose de l'extrémité arrière du pont.A third technique notably described in a variant in FR-A-1,553,517 consists in using an arm of fixed and limited length on which the bridge is made to slide. This arm is initially subjected to a rotation so as to tilt the bridge and allow the removal of its front end on the opposite bank of the breach. It further comprises an articulated front section allowing, under the effect of a jack, to deposit the rear end of the bridge on the bank where the machine is located. This technique partially overcomes the drawbacks of the first two techniques described above. However, the rotation of the arm is at the expense of the living space of the cabin and poses ergonomic problems. In addition, the arm must have a hinged section for removing the rear end of the bridge.

La présente invention concerne un engin poseur de ponts du type de celui décrit ci-dessus, palliant les inconvénients de celui-ci et a à cet effet pour objectif de fournir un engin poseur de ponts permettant une bonne visibilité du site de dépose et comportant une cabine d'un volume appréciable du point de vue ergonomique.The present invention relates to a bridge-laying machine of the type described above, overcoming the drawbacks thereof and has for this purpose the objective of providing a bridge-laying machine allowing good visibility of the drop-off site and comprising a cabin of appreciable volume from an ergonomic point of view.

Un autre objectif est de fournir un engin poseur de ponts doté d'un bras manipulateur simplifié, dépourvu de tout organe spécifique pour la dépose.Another objective is to provide a bridge-laying machine equipped with a simplified manipulator arm, devoid of any specific member for removal.

A cet effet, l'invention concerne un engin poseur de ponts du type comportant :

  • un châssis doté vers une de ses extrémités, dite avant, d'une cabine,
  • un pont constitué d'au moins une travure et disposé sur le châssis,
  • un bras manipulateur adapté pour supporter le pont lors de la mise en place de ce dernier au-dessus d'une brèche,
  • des moyens de guidage et d'entraînement du pont associés au bras manipulateur et adaptés pour engendrer un coulissement de ce pont le long dudit bras manipulateur de façon à le positionner en porte-à-faux à l'avant de l'engin,
  • et des moyens de basculement du pont adaptés pour permettre la dépose de ce dernier. Un tel engin a été décrit dans DE-A-2.846.182, par exemple.
To this end, the invention relates to a bridge-laying machine of the type comprising:
  • a chassis fitted towards one of its ends, called the front, with a cabin,
  • a bridge consisting of at least one span and disposed on the chassis,
  • a manipulator arm adapted to support the bridge when the latter is placed over a breach,
  • means for guiding and driving the bridge associated with the manipulator arm and adapted to generate a sliding of this bridge along said manipulator arm so as to position it in cantilever at the front of the machine,
  • and means for tilting the bridge adapted to allow the latter to be removed. Such a device has been described in DE-A-2,846,182, for example.

Selon l'invention, cet engin se caractérise en ce que :

  • le bras manipulateur est assujetti sur la cabine,
  • les moyens de basculement sont adaptés pour faire pivoter ensemble la cabine et le bras manipulateur par rapport au châssis, de façon à incliner la cabine en même temps que le bras lors de la dépose du pont.
According to the invention, this machine is characterized in that:
  • the manipulator arm is fixed on the cabin,
  • the tilting means are adapted to pivot the cabin and the manipulator arm relative to the chassis, so as to tilt the cabin at the same time as the arm when removing the bridge.

Ce basculement vers l'avant de l'ensemble bras manipulateur-cabine procure de nombreux avantages. En premier lieu, le volume de la cabine n'est pas entamé par la rotation du bras, ce qui est particulièrement appréciable du point de vue ergonomique. De plus, la visibilité vers le site de dépose est améliorée par rapport aux engins connus. Enfin, la conception du bras est très simplifiée puisque ce dernier ne comporte aucun équipement spécifique contribuant à la mise en oeuvre du pont.This forward tilting of the manipulator-cabin arm assembly provides many advantages. First, the volume of the cabin is not affected by the rotation of the arm, which is particularly appreciable from an ergonomic point of view. In addition, visibility to the drop-off site is improved compared to known vehicles. Finally, the design of the arm is very simplified since the latter does not include any specific equipment contributing to the implementation of the bridge.

Selon un mode de réalisation préférentiel, les moyens de basculement de la cabine et du bras manipulateur comprennent au moins un vérin attelé respectivement sur le châssis et sur ladite cabine.According to a preferred embodiment, the means for tilting the cabin and the manipulator arm comprise at least one jack coupled respectively to the chassis and to said cabin.

En outre, selon une autre caractéristique de l'invention, cet engin comprend :

  • des moyens de guidage en translation longitudinale du bras manipulateur rendant ledit bras mobile entre une position, dite de transport, où il s'étend sur la cabine et, sur sa plus grande longueur, au-dessus du châssis, et une position, dite de dépose, où il s'étend sur la cabine et, sur sa plus grande longueur, en porte-à-faux à l'avant de ladite cabine,
  • des moyens d'entraînement du bras manipulateur aptes à le déplacer entre sa position de transport et sa position de dépose.
In addition, according to another characteristic of the invention, this machine comprises:
  • means for guiding in longitudinal translation of the manipulator arm making said arm movable between a position, called transport, where it extends over the cabin and, over its greatest length, above the chassis, and a position, called removal, where it extends over the cabin and, over its greatest length, overhanging the front of said cabin,
  • arm drive means manipulator able to move it between its transport position and its removal position.

Ce mouvement de translation longitudinale du bras permet de réaliser un engin de longueur réduite en condition de transport, tout en permettant une rotation du bras suffisante pour la dépose du pont.This longitudinal translational movement of the arm makes it possible to produce a machine of reduced length in transport condition, while allowing sufficient rotation of the arm for removing the bridge.

L'engin poseur de ponts représenté aux figures comporte un châssis routier 1 sur roues 2 portant un pont décomposé en deux travures superposées, inférieure 3 et supérieure 4, à structure en treillis. Chacune de ces travures comporte deux chemins de roulement parallèles 3a, 3b, 4a, 4b reliés par des entretoises 5.The bridge-laying machine shown in the figures comprises a road chassis 1 on wheels 2 carrying a bridge broken down into two superimposed spans, lower 3 and upper 4, with a lattice structure. Each of these spans comprises two parallel raceways 3a, 3b, 4a, 4b connected by spacers 5.

A l'avant du châssis 1 se trouve disposée une cabine 6 séparée en deux compartiments latéraux 6a, 6b solidarisés à un bâti central 7 articulé sur le châssis 1 de façon à pouvoir basculer vers l'avant. Ce basculement est commandé par un vérin 8 articulé, d'une part, sur le châssis 1 et d'autre part sur ledit bâti 7.At the front of the chassis 1 is located a cabin 6 separated into two lateral compartments 6a, 6b secured to a central frame 7 articulated on the chassis 1 so as to be able to tilt forward. This tilting is controlled by a jack 8 articulated, on the one hand, on the chassis 1 and on the other hand on said frame 7.

This manipulator arm 9, of generally shaped section rectangular parallelepiped, has an upper face comprising two lateral recesses defining two upper planar rolling surfaces 10. It is also provided with two longitudinal members 11 arranged longitudinally, each on one of its lateral faces, and comprising horizontal bearing faces defining two other lower flat rolling surfaces.

Les travures supérieure 4 et inférieure 3 sont quant à elles dotées de galets 12 supérieurs et inférieurs répartis longitudinalement le long de ces travures et agencés en regard des noeuds de la structure en treillis de façon à venir en appui respectivement sur les surfaces de roulement supérieur 10 et inférieur 11 du bras manipulateur 9. Il est à noter que ce dispositif de guidage longitudinal des travures 3, 4 sur le bras manipulateur 9 permet d'obtenir un gain de masse notable par rapport aux dispositifs connus pour lesquels les travures sont munies de rails de guidage à l'intérieur desquels se logent des galets solidaires du bras.The upper 4 and lower 3 spans are in turn provided with upper and lower rollers 12 distributed longitudinally along these spans and arranged opposite the nodes of the trellis structure so as to come into abutment respectively on the upper rolling surfaces 10 and lower 11 of the manipulator arm 9. It should be noted that this device for longitudinal guide of the spans 3, 4 on the manipulator arm 9 makes it possible to obtain a significant gain in mass compared to the known devices for which the spans are provided with rails. guide inside which are housed rollers integral with the arm.

L'extrémité avant du bras manipulateur 9 comporte, en outre, une rampe inclinée 13 agencée pour coopérer avec un galet supérieur 12 de la travure inférieure 3, afin de faire pivoter cette travure et d'obtenir un pont doté d'un contre-flèche, tel qu'on le verra plus loin.The front end of the manipulator arm 9 further comprises an inclined ramp 13 arranged to cooperate with an upper roller 12 of the lower span 3, in order to pivot this span and obtain a bridge provided with a counter-jib. , as we will see later.

Le bras manipulateur 9 comporte, par ailleurs, deux glissières inférieures latérales 14 à l'intérieur desquelles sont logés des patins de guidage 15 solidaires du bâti 7 et adaptés pour assurer le guidage longitudinal de ce bras 9 et éviter qu'il ne bascule lorsqu'il se trouve en porte-à-faux à l'avant du châssis 1.The manipulator arm 9 also comprises two lower lateral slides 14 inside which are housed guide pads 15 integral with the frame 7 and adapted to ensure the longitudinal guidance of this arm 9 and to prevent it from tipping over when it is cantilevered at the front of chassis 1.

Des galets de guidage horizontaux 16 solidaires du bâti 7 sont également logés dans les glissières 14 de façon à assurer un guidage transversal du bras manipulateur 9.Horizontal guide rollers 16 integral with the frame 7 are also housed in the slides 14 so as to ensure transverse guidance of the manipulator arm 9.

Les moyens de déplacement associés à ce bras manipulateur et adaptés pour le positionner en porte-à-faux à l'avant du châssis 1, comprennent une crémaillère 17 solidaire dudit bras et s'étendant le long de ce dernier, et un pignon moteur 18 associé entraîné par un moto-réducteur 19, et contre lequel la crémaillère 17 est plaquée par un contre-galet d'appui 20.The displacement means associated with this manipulator arm and adapted to position it in cantilever at the front of the chassis 1, comprise a rack 17 integral with said arm and extending along the latter, and a drive pinion 18 associated driven by a geared motor 19, and against which the rack 17 is pressed by a support counter-roller 20.

Le bras manipulateur intègre, par ailleurs, des moyens d'entraînement des travures 3, 4 adaptés pour les déplacer longitudinalement le long de ce bras. Ces moyens d'entraînement comprennent une chaîne sans fin horizontale 21 entraînée par un pignon moteur 22 , agencée pour engréner ponctuellement sur des doigts 23 disposés à intervalles réguliers sous les entretoises 5 des travures 3, 4.The manipulator arm also incorporates means for driving the spans 3, 4 adapted to move them longitudinally along this arm. These drive means comprise a horizontal endless chain 21 driven by a motor pinion 22, arranged to mesh punctually on fingers 23 arranged at regular intervals under the spacers 5 of the spans 3, 4.

Ces doigts 23 associés deux par deux présentent la forme d'une chape dans laquelle viennent se loger des plots d'entraînement horizontaux 24 faisant saillie latéralement de part et d'autre des maillons de la chaîne d'entraînement 21. Tels que représentés aux figures 12, 13 et 14, ces doigts 23 et ces plots 24 sont, en outre adaptés pour se dissocier lorsque l'inclinaison du bras manipulateur 9 par rapport aux travures 3, 4 est supérieure à une valeur déterminée.These fingers 23 associated two by two have the shape of a yoke in which are housed horizontal drive studs 24 projecting laterally on either side of the links of the drive chain 21. As shown in the figures 12, 13 and 14, these fingers 23 and these studs 24 are further adapted to dissociate when the inclination of the manipulator arm 9 relative to the spans 3, 4 is greater than a determined value.

A l'arrière du châssis 1 se trouve disposé un bras pivotant 25 articulé sur ledit châssis et doté de moyens d'accrochage de la travure supérieure 4. Ces moyens d'accrochage sont destinés à maintenir la travure supérieure 4 pendant le transport et lors des déplacements de cette travure destinés à l'amener dans le prolongement de la travure inférieure 3 .At the rear of the frame 1 is arranged a pivoting arm 25 articulated on said frame and provided with means for hooking the upper span 4. These hooking means are intended to hold the upper span 4 during transport and during displacements of this span intended to bring it into the extension of the lower span 3.

Tel que représenté aux figures 6 et 7, ces moyens d'accrochage comprennent des mâchoires 26 adaptées pour se refermer sur le galet inférieur 12 d'extrémité de la travure supérieure 4, lorsque ce dernier vient pénétrer dans ladite mâchoire, lors d'un coulissement vers l'arrière de cette travure le long du bras manipulateur 9.As shown in Figures 6 and 7, these attachment means comprise jaws 26 adapted to close on the lower roller 12 at the end of the upper span 4, when the latter comes into said jaw, during sliding towards the rear of this span along the manipulator arm 9.

Un organe de blocage permet, en outre, de maintenir la mâchoire 26 dans sa positon fermée et de libérer son ouverture sur commande afin de permettre un coulissement vers l'avant de la travure supérieure 4. Cet organe de blocage se compose d'un verrou 27 poussé par un ressort 28 et de forme adaptée pour se loger dans un décrochement externe 26a de la mâchoire 26. Le retrait de ce verrou 27 est par ailleurs commandé par un vérin 29.A blocking member also makes it possible to keep the jaw 26 in its closed position and to release its opening on command so as to allow the upper span 4 to slide forward. This blocking member consists of a lock 27 pushed by a spring 28 and of a shape adapted to be housed in an external recess 26a of the jaw 26. The withdrawal of this lock 27 is also controlled by a jack 29.

Le bras pivotant 25 représenté à la figure 8 dans la position de transport et portant ces moyens d'accrochage est adapté pour faire coulisser longitudinalement la travure supérieure 4 vers l'arrière et la faire pivoter de façon à l'amener dans le prolongement de la travure inférieure 3, pivotement au cours duquel cette travure supérieure 4 prend appui sur un support 30 faisant saillie sur le châssis 1.The pivoting arm 25 shown in FIG. 8 in the transport position and carrying these hooking means is adapted to make the upper span 4 slide longitudinally towards the rear and rotate it so as to bring it in line with the lower span 3, pivoting during which this upper span 4 is supported on a support 30 projecting from chassis 1.

A cet effet ce bras pivotant 25 comporte un premier vérin 31 portant les moyens d'accrochage et agencé de façon à soulever l'extrémité arrière de la travure supérieure 4 (figure 9). Le corps de ce premier vérin est assujetti sur un bras intermédiaire 32 articulé sur le châssis 1 de façon à pouvoir pivoter vers l'arrière sous l'action d'un deuxième vérin 33 articulé sur le châssis 1 et sur ce bras intermédiaire 32 (figure 10).To this end, this pivoting arm 25 comprises a first jack 31 carrying the hooking means and arranged so as to raise the rear end of the upper span 4 (FIG. 9). The body of this first cylinder is fixed on an intermediate arm 32 articulated on the chassis 1 so as to be able to pivot backwards under the action of a second cylinder 33 articulated on the chassis 1 and on this intermediate arm 32 (FIG. 10).

Un troisième vérin 34 articulé, d'une part, sur l'extrémité de la tige du deuxième vérin 33 par l'intermédiaire d'une pièce 35 fixée sur le bras intermédiaire 32 et, d'autre part, sur ce bras intermédiaire 32, permet enfin lors de son déploiement d'augmenter la course de rotation de la travure supérieure 4, de façon à dégager celle-ci. Lorsque ce troisième vérin 34 est rétracté, il permet ensuite de ramener la travure supérieure 4 selon une position sensiblement horizontale.A third jack 34 articulated, on the one hand, on the end of the rod of the second jack 33 by means of a part 35 fixed on the intermediate arm 32 and, on the other hand, on this intermediate arm 32, finally allows during its deployment to increase the rotational stroke of the upper span 4, so as to release it. When this third cylinder 34 is retracted, it then makes it possible to bring the upper span 4 back into a substantially horizontal position.

En dernier lieu, les travures 3, 4 portées par cet engin comportent des faces de jonction 3c, 4c inclinées de façon à définir un dièdre ouvert vers le bas lorsque lesdites travures sont positionnées bout à bout.Finally, the cross-sections 3, 4 carried by this machine comprise junction faces 3c, 4c inclined so as to define a dihedron open downwards when said cross-sections are positioned end to end.

Ces faces de jonction 3c, 4c sont, en outre, dotées de moyens de centrage, d'articulation et de verrouillage permettant dans un premier temps d'articuler les travures 3, 4 en partie haute et dans un deuxième temps de les verrouiller en partie basse, après le pivotement de la travure inférieure 3 dû à son passage sur la rampe de guidage inclinée 13.These junction faces 3c, 4c are furthermore provided with centering, articulation and locking means making it possible, at first, to articulate the cross-sections 3, 4 in the upper part and, secondly, to lock them in part. low, after the pivoting of the lower span 3 due to its passage on the inclined guide ramp 13.

Les moyens de centrage sont répartis transversalement sur la longueur de la face de jonction 3c, 4c des travures 3, 4 en partie haute de celles-ci. Tels que représentés à la figure 16, ils se composent d'une pluralité d'axes horizontaux 36 assujettis sur les faces de jonction 3c, 4c des travures 3, 4 et, pour chacun de ces axes 36, d'une chape 37 assujettie sur la face de jonction 4c, 3c de l'autre travure 4, 3 en position conjuguée dudit axe.The centering means are distributed transversely over the length of the junction face 3c, 4c of the spans 3, 4 in the upper part thereof. As shown in Figure 16, they consist of a plurality of horizontal axes 36 secured on the junction faces 3c, 4c of the spans 3, 4 and, for each of these axes 36, a yoke 37 secured on the junction face 4c, 3c of the other span 4, 3 in the conjugate position of said axis.

Les moyens d'articulation et de verrouillage comprennent plusieurs ensembles tels que représentés aux figures 17 et 18, comportant chacun un axe horizontal 38 assujetti sur la face de jonction 3c, 4c d'une travure 3, 4 et une mâchoire 39 assujettie sur la face de jonction 4c, 3 de l'autre travure 4, 3, en position conjuguée dudit axe, de façon à venir se refermer sur ce dernier. Un organe de blocage permet, en outre, de maintenir la mâchoire 39 dans sa position fermée. Cet organe de blocage se compose d'un verrou 40 poussé par un ressort 41 et de forme adaptée pour venir se loger dans un décrochement externe 39a de la mâchoire 39.The articulation and locking means comprise several assemblies as shown in Figures 17 and 18, each comprising a horizontal axis 38 fixed on the junction face 3c, 4c of a span 3, 4 and a jaw 39 secured on the junction face 4c, 3 of the other span 4, 3, in conjugate position of said axis, so as to close on the latter. A locking member also makes it possible to maintain the jaw 39 in its closed position. This blocking member consists of a bolt 40 pushed by a spring 41 and of a shape adapted to be housed in an external recess 39a of the jaw 39.

Afin de permettre un déverrouillage automatique, le bras manipulateur 9 est, par ailleurs, doté latéralement de surfaces de roulement présentant une rampe inclinée 42, en position appropriée, sur laquelle se déplace un galet 43 relié au verrou 40 par une tringlerie 44 adaptée pour entraîner le recul de ce verrou 40 lorsque ce galet 43 remonte sur cette rampe 42.In order to allow automatic unlocking, the manipulator arm 9 is, moreover, laterally provided with rolling surfaces having an inclined ramp 42, in the appropriate position, on which a roller 43 moves connected to the lock 40 by a linkage 44 adapted to drive the backward movement of this lock 40 when this roller 43 rises on this ramp 42.

Tel que représenté à la figure 15, les travures 3, 4 comportent deux ensembles d'articulation en partie haute, disposés chacun sur un chemin de roulement 3a, 3b, 4a, 4b et comportant chacun leur propre galet de déverrouillage 43.As shown in FIG. 15, the spans 3, 4 comprise two articulation assemblies in the upper part, each arranged on a raceway 3a, 3b, 4a, 4b and each comprising their own unlocking roller 43.

Ces travures 3, 4 comportent, en outre, huit ensembles de verrouillage jumelés deux à deux, en partie basse. Chaque chemin de roulement 3a, 3b, 4a, 4b comporte deux ensembles jumelés disposés latéralement de part et d'autre de ce chemin de roulement et reliés par une tringlerie 45 de façon à être actionnés par un galet de déverrouillage 43 unique.These spans 3, 4 further comprise eight locking assemblies twinned two by two, in the lower part. Each raceway 3a, 3b, 4a, 4b comprises two twin assemblies arranged laterally on either side of this raceway and connected by a linkage 45 so as to be actuated by a single unlocking roller 43.

En dernier lieu, le châssis 1 comporte, à l'avant, un patin d'appui rétractable 46 actionné par un vérin 47 et destiné à améliorer la stabilité pendant la phase de lancement du pont.Finally, the chassis 1 comprises, at the front, a retractable support pad 46 actuated by a jack 47 and intended to improve stability during the launching phase of the bridge.

Les différents éléments constitutifs de l'engin poseur de ponts ayant été décrits, les différentes phases de reconstitution et de dépose du pont sont explicitées ci-dessous en référence aux figures 19a à 19n, à partir de la configuration de roulage dans laquelle les deux travures 3, 4 sont superposées sur l'engin (figure 19a).The various constituent elements of the bridge-laying machine having been described, the different phases of reconstruction and removal of the bridge are explained below with reference to FIGS. 19a to 19n, starting from the running configuration in which the two spans 3, 4 are superimposed on the machine (Figure 19a).

Dans un premier temps, la travure supérieure 4 est soulevée à l'aide du premier vérin 31 du bras pivotant 25 (figure 19c) et le bras manipulateur 9 est amené à coulisser vers l'avant entraînant avec lui la travure inférieure 3 (figure 19 c), jusqu'à une position avant où il se trouve partiellement en porte-à-faux par rapport à la cabine 6.At first, the span upper 4 is raised by means of the first jack 31 of the pivoting arm 25 (FIG. 19c) and the manipulator arm 9 is caused to slide forward bringing with it the lower span 3 (FIG. 19 c), to a front position where it is partially cantilevered from the cab 6.

La travure inférieure 3 est alors elle-même amenée à coulisser sur le bras manipulateur 9 (figure 19d), puis la travure supérieure 4 amenée à pivoter par l'intermédiaire du bras pivotant 25 (figure 19e, 19f, 19g) selon le processus explicité ci-avant en référence aux figures 8 à 11, jusqu'à venir dans le prolongement de la travure inférieure 3 (figure 19h).The lower span 3 is then itself caused to slide on the manipulator arm 9 (FIG. 19d), then the upper span 4 brought to pivot via the pivoting arm 25 (FIG. 19e, 19f, 19g) according to the process explained. above with reference to Figures 8 to 11, up to the extension of the lower span 3 (Figure 19h).

Cette travure inférieure 3 est ensuite légèrement reculée de façon que, d'une part, les axes 36 viennent se centrer dans les chapes 37 et, d'autre part, les axes 38 viennent refermer les mâchoires 39, qui sont alors verrouillées par l'action du verrou 40 poussé par le ressort 41. Une articulation étant ainsi créée en partie haute des travures 3, 4, la travure supérieure 4 est libérée par l'action du vérin 29 qui entraîne le retrait du verrou 27 et autorise l'ouverture de la machoire 26.This lower span 3 is then slightly moved back so that, on the one hand, the axes 36 come to center in the yokes 37 and, on the other hand, the axes 38 close the jaws 39, which are then locked by the action of the bolt 40 pushed by the spring 41. A joint thus being created in the upper part of the cross-sections 3, 4, the upper cross-section 4 is released by the action of the jack 29 which causes the withdrawal of the lock 27 and authorizes the opening of the jaw 26.

Les travures 3, 4 articulées en partie haute sont alors amenées à coulisser sur le bras manipulateur 9. Lors de ce coulissement, la travure inférieure 3 est assujettie à une rotation lors de son passage sur la rampe inclinée 13 (figure 19i). Suite à cette rotation, les mâchoires inférieures 39 viennent se refermer sur les axes 38, terminant la recomposition du pont qui est alors complètement avancé au-dessus de l'obstacle (figure 19j).The spans 3, 4 articulated in the upper part are then caused to slide on the manipulator arm 9. During this sliding, the lower span 3 is subjected to rotation during its passage on the inclined ramp 13 (FIG. 19i). Following this rotation, the lower jaws 39 close on the axes 38, completing the recomposition of the bridge which is then completely advanced above the obstacle (Figure 19j).

L'action du vérin 8 permet alors de faire basculer la cabine 6 et le bras manipulateur 9 et de déposer successivement les extrémités des travures 3, 4 sur le sol (figures 19k, 19l).The action of the jack 8 then makes it possible to tilt the cabin 6 and the manipulator arm 9 and to successively deposit the ends of the spans 3, 4 on the ground (Figures 19k, 19l).

Une fois le pont déposé, une rotation supplémentaire de la cabine 6 et du bras manipulateur 9 permet de libérer les plots d'entraînement 24 qui se dissocient des doigts 23, et le bras manipulateur 9 est finalement amené à coulisser vers l'arrière tandis que la cabine 6 est ramenée dans sa position de roulage sous l'action du vérin 8.Once the bridge has been removed, an additional rotation of the cabin 6 and of the manipulator arm 9 makes it possible to release the drive studs 24 which dissociate from the fingers 23, and the manipulator arm 9 is finally caused to slide backwards while cabin 6 is brought back in its rolling position under the action of the jack 8.

Tel que représenté aux figures 20a à 20i, cet engin poseur de ponts permet également de déposer et de reprendre successivement une ou deux travures sur le sol.As shown in Figures 20a to 20i, this bridge-laying machine also allows to deposit and resume successively one or two spans on the ground.

Il présente également l'avantage, tel que représenté aux figures 21a et 21b, de pouvoir déposer les travures assemblées au-dessus d'une brèche dont les berges présentent un dénivellé l'une par rapport à l'autre.It also has the advantage, as shown in FIGS. 21a and 21b, of being able to deposit the assembled spans over a breach, the banks of which have a difference in level with respect to each other.
