Description

La présente invention a pour objet un système d'assemblage d'une travure destinée notamment au franchissement de brèches par des engins dits lourds par exemple par des engins blindés.The present invention relates to a system for assembling a span intended in particular for crossing breaches by so-called heavy vehicles, for example by armored vehicles.

Le franchissement de brèches ou autres passages entre deux bords surélevés par des engins dits lourds réclame des travures présentant non seulement une aptitude toute particulière à la rapidité de pose, mais aussi une légèreté facilitant leur transport et leur mise en oeuvre.The crossing of breaches or other passages between two raised edges by so-called heavy equipment requires spans having not only a very particular aptitude for the speed of installation, but also a lightness facilitating their transport and their implementation.

Ces impératifs de légèreté et de maniabilité sont contradictoires avec les qualités de robustesse, de solidité mécanique et de résistance à la flexion, compte-tenu du poids des engins pouvant utilisés ces travures.These imperatives of lightness and maneuverability are contradictory with the qualities of robustness, mechanical solidity and resistance to bending, taking into account the weight of the machines that can use these spans.

Ces travures sont généralement soit des travures de type en ciseaux, soit des travures simples en plusieurs trançons aboutables.These spans are generally either spans of the scissor type, or simple spans in several connectable sections.

Les travures de type en ciseaux comprennent deux au trois éléments indissociables qui se développent par rotation dans un plan vertical autour de l'axe commun de deux éléments.The scissor-type span comprises two to three inseparable elements which develop by rotation in a vertical plane around the common axis of two elements.

Après déploiement, ces travures peuvent être déposées sait au moyen d'une flèche, sait à l'aide d'un manipulateur.After deployment, these spans can be placed knows by means of an arrow, knows using a manipulator.

Ces travures de type en ciseaux ont pour principal inconvénient le fait que lors du déploiement ou de la dépose, l'ensemble de la travure se trouve être en porte à faux vis à vis du véhicule porteur, ce qui oblige à limiter le poids des travures et donc entraine une limitation dans la longueur des travures utilisées et de ce fait des brèches qu'il est possible de franchir.The main drawback of these scissor-type bridges is that during deployment or removal, the entire bridging is found to be cantilevered against the carrier vehicle, which means that the weight of the bridges has to be limited and therefore leads to a limitation in the length of the span used and therefore breaches which it is possible to cross.

De plus, lors du déploiement ou de la dépose, la travure s'élève à une hauteur telle qu'elle est facilement détectable par les moyens d'observations ennemis. D'autre part, le système d'articulation et de déploiement alourdit considérablement l'ensemble ce qui oblige à limiter la portée, car les efforts sur le système de déploiement en porte à faux deviennent trop importants.In addition, during deployment or removal, the span rises to a height such that it is easily detectable by means of enemy observations. On the other hand, the articulation and deployment system considerably increases the overall weight, which makes it necessary to limit the range, because the efforts on the cantilever deployment system become too great.

Dans le cas d'une travure simple, les tronçons sont transportés de manière superposée les uns par rapport aux autres, puis déployés en translation par un manipulateur qui sert également à la dépose de ladite travure.In the case of a single span, the sections are transported superimposed relative to one another, then deployed in translation by a manipulator which is also used for the removal of said span.

Mais, dans ce type de travure, les tronçons doivent être, avant la dépose, centrés, assemblés et verrouillés les uns par rapport aux autres.However, in this type of span, the sections must be, before removal, centered, assembled and locked with respect to each other.

Jusqu'à présent, l'assemblage des tronçons est réalisé par des arganes de centrage et de liaison formés par exemple par des vérrous au des clavettes au encore des ensembles mécaniques comprenant un dispositif à crémaillère et à cliquet actionné par un poussoir.Until now, the sections have been assembled by centering and connecting members formed for example by locks at the keys or at the mechanical assemblies comprising a rack-and-pinion device actuated by a pusher.

Les organes de centrage et de liaison utilisés sont bien souvent compliqués à mettre en oeuvre, compte-tenu des dimensions des tronçons, ce qui nécéssite la présence hors du véhicule de plusieurs servants pour commander et guider les manoeuvres.The centering and connecting members used are very often complicated to implement, taking into account the dimensions of the sections, which requires the presence outside the vehicle of several servants to control and guide the maneuvers.

Cette nécessité représente une restriction importante à l'utilisation de telles travures puisqu'elle en interdit la mise en oeuvre en atmosphère pollué tel que l'on peut en rencontrer lors de conflits nucléaires, bactériologiques ou chimiques.This necessity represents a significant restriction on the use of such bridges since it prohibits their use in a polluted atmosphere such as may be encountered during nuclear, bacteriological or chemical conflicts.

La présente invention a donc pour but de fournir un système d'assemblage d'une travure qui évite les inconvénients précités et qui soit particulièrement simple et facile à mettre en oeuvre.The present invention therefore aims to provide a system for assembling a span which avoids the aforementioned drawbacks and which is particularly simple and easy to implement.

La présente invention a donc pour objet un système d'assemblage d'une travure pour le franchissement de brèches comprenant au moins deux tronçons destinés à être placés bout à bout pour former au moins un chemin de roulement et dont au moins les extrémités en regard sont munies de moyens de liaison, caractérisé en ce que les moyens de liaison comportent des organes d'emboitement de forme complémentaire formés à l'extrémité correspondante de chaque tronçon par une succession de parties en saillie et de creux décalés par rapport à ceux de l'extrémité de l'autre tronçon placé en regard.The present invention therefore relates to a system for assembling a span for crossing breaches comprising at least two sections intended to be placed end to end to form at least one raceway and of which at least the opposite ends are provided with connection means, characterized in that the connection means comprise interlocking members of complementary shape formed at the corresponding end of each section by a succession of projecting parts and recesses offset from those of the end of the other section placed opposite.

Selon d'autres caractéristiques de l'invention:

  • les deux extrémités de chaque tronçon sont pourvues de parties en saillie et de creux, lesdites parties en saillie et lesdits creux de chaque extrémités opposées dudit tronçon étant décalés les uns par rapport aux autres,
  • les parties en saillie ont un profil trapézoïdal convergent vers l'extrémité du tronçon,
  • les parties en saillie possèdent une base de section polygonale,
  • les creux se prolongent par un logement ménagé à l'intérieur du tronçon,
  • chaque logement a un profil complémentaire au profil de la partie en saillie associée,
  • le profil de chaque logement est trapézoïdal convergent vers le centre du tronçon,
  • le fond de chaque logement est muni d'un orifice perpendiculaire à l'axe dudit logement et débauchant de part et d'autre du tronçon,
  • chaque tronçon comporte sur sa face formant chemin de roulement un tapis de protection recouvrant les arganes d'emboîtement,
  • les tapis de deux tronçons assemblés l'un à l'autre se chevauchent au niveau du plan de jointure desdits tronçons.
According to other characteristics of the invention:
  • the two ends of each section are provided with projecting parts and recesses, said projecting parts and said recesses of each opposite end of said section being offset with respect to each other,
  • the projecting parts have a trapezoidal profile converging towards the end of the section,
  • the projecting parts have a base of polygonal section,
  • the recesses are extended by a housing formed inside the section,
  • each housing has a profile complementary to the profile of the associated projecting part,
  • the profile of each housing is trapezoidal converging towards the center of the section,
  • the bottom of each housing is provided with an orifice perpendicular to the axis of said housing and emerging from either side of the section,
  • each section has on its face forming a raceway a protective mat covering the interlocking argan members,
  • the belts of two sections assembled to one another overlap at the level of the joining plane of said sections.

L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels:

  • la Fig. 1 est une vue de dessus de deux tronçons d'une travure munie d'un système d'assemblage selon l'invention,
  • la Fig. 2 est une vue latérale d'un tronçon de la travure de la Fig. 1,
  • la Fig. 3 est une vue à plus grande échelle montrant l'assemblage de deux tronçons placés bout à bout,
  • la Fig. 4 est une vue en coupe selon la ligne 4-4 de la Fig. 3,
  • la Fig. 5 est une vue du dessus des extrémités en regard de deux tronçons opposés de la travure, munis chacun d'un tapis de protection,
  • la Fig. 6 est une vue latérale de deux tronçons assemblés montrant le chevauchement des tapis de protection.
The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings in which:
  • Fig. 1 is a top view of two sections of a span provided with an assembly system according to the invention,
  • Fig. 2 is a side view of a section of the span of FIG. 1,
  • Fig. 3 is a view on a larger scale showing the assembly of two sections placed end to end,
  • Fig. 4 is a sectional view along line 4-4 of FIG. 3,
  • Fig. 5 is a top view of the opposite ends of two opposite sections of the span, each provided with a protective mat,
  • Fig. 6 is a side view of two assembled sections showing the overlap of the protective mats.

La travure représentée aux Fig. 1 à 3 se compose de plusieurs paires de tronçons 1, les tronçons de chaque paire étant reliés entre eux par des traverses 2.The span shown in Figs. 1 to 3 consists of several pairs of sections 1, the sections of each pair being interconnected by crosspieces 2.

Pour le franchissement de brèches plusieurs paires de tronçons 1 sont placées bout à bout pour former au mains un chemin de roulement permettant le passage de véhicules.For crossing breaches, several pairs of sections 1 are placed end to end to form in the hands a raceway allowing the passage of vehicles.

A cet effet, chaque extrémité 1a et 1b de chacun des tronçons 1 comporte des organes d'emboîttement de forme complémentaire désignés par la référence 10.To this end, each end 1a and 1b of each of the sections 1 comprises interlocking members of complementary shape designated by the reference 10.

Ces organes d'emboîtement sont formés par une succession de parties en saillie 11 et de creux 12.These interlocking members are formed by a succession of projecting parts 11 and recesses 12.

Comme on peut le voir sur la Fig. 2 les parties en saillie 11 ont un profil trapézoïdal convergent vers l'extrémité du tronçon 1 et possèdent une base de section polygonale.As can be seen in Fig. 2 the projecting parts 11 have a trapezoidal profile converging towards the end of the section 1 and have a base of polygonal section.

Chaque creux 12 se prolonge par un logement 13 ménagé à l'intérieur du tronçon 1 et de profil complémentaire au profil des parties en saillie 11, c'est à dire trapézoïdal et convergent vers le centre dudit tronçon.Each recess 12 is extended by a housing 13 formed inside the section 1 and of profile complementary to the profile of the projecting parts 11, that is to say trapezoidal and converging towards the center of said section.

De plus, le fond de chaque logement 13 est perçé d'un orifice 14 perpendiculaire à l'axe dudit logement et débauchant de part et d'autre du tronçon.In addition, the bottom of each housing 13 is pierced with an orifice 14 perpendicular to the axis of said housing and opening out on either side of the section.

Ces orifices 14 permettent de nettoyer les logements 13.These orifices 14 make it possible to clean the housings 13.

Les parties en saillie 11 et les creux 12 de chaque extrémité 1a et 1b du tronçon 1 sont décalées les unes par rapport aux autres.The projecting parts 11 and the recesses 12 of each end 1a and 1b of the section 1 are offset from one another.

Ainsi, à une partie en saillie 11 de l'extrémité 1a d'un tronçon 1 correspond un creux 12 de l'extrémité 1b de ce même tronçon.Thus, a protruding part 11 of the end 1a of a section 1 corresponds to a recess 12 of the end 1b of this same section.

On peut également concevoir des tronçons comportant seulement à l'une des extrémités des parties en saillie 11 et des creux 12, chaque partie en saillie 11 et chaque creux 12 étant décalés par rapport à ceux de l'extrémité de l'autre tronçon placé en regard au moment de l'assemblage.It is also possible to design sections comprising only at one end of the protruding parts 11 and recesses 12, each protruding part 11 and each recess 12 being offset with respect to those of the end of the other section placed in look at the time of assembly.

Lors de l'assemblage de chaque paire de tronçons 1 avec la paire de tronçons placée en regard, les parties en saillie 11 de chaque tronçon pénètrent dans les creux 12 et viennent se placer dans les logements 13 du tronçon opposé comme représenté sur les Figs. 3 et 4.During the assembly of each pair of sections 1 with the pair of sections placed facing each other, the projecting parts 11 of each section penetrate into the recesses 12 and are placed in the housings 13 of the opposite section as shown in FIGS. 3 and 4.

Grâce à la forme profilée déterminée des parties en saillie 11 et des logements 13, les tronçons s'alignent donc automatiquement les uns par rapport aux autres au moment de la formation de la travure ce qui permet de s'affranchir des différences de niveau entre lesdits tronçons.Thanks to the determined profiled shape of the projecting parts 11 and of the housings 13, the sections are therefore automatically aligned with respect to each other at the time of the formation of the span, which makes it possible to overcome the differences in level between said sections. sections.

Les organes d'emboîtement 10 permettent de pouvoir utiliser un nombre de paires de tronçons 1 correspondant aux dimensions de la brèche à franchir.The interlocking members 10 make it possible to use a number of pairs of sections 1 corresponding to the dimensions of the breach to be crossed.

Cette disposition permet également d'éviter les manoeuvres de positionnement et de centrage d'un tronçon par rapport à l'autre, qui sont dans la plupart des cas fastidieuses compte-tenu du poids et des dimensions des tronçons.This arrangement also makes it possible to avoid the positioning and centering maneuvers of one section relative to the other, which are in most cases tedious taking into account the weight and dimensions of the sections.

Par ailleurs, la face supérieure de chaque tronçon est recouverte, au niveau des organes d'emboîtement 10, d'un tapis de protection 15 (Figs 5 et 6) muni d'aspérités empêchant le patinage des véhicules.Furthermore, the upper face of each section is covered, at the interlocking members 10, with a protective mat 15 (FIGS. 5 and 6) provided with roughness preventing the vehicles from slipping.

L'extrémité 15a du tapis 15 recouvre partiellement les parties en saillie 11 et les creux 12 de l'extrémité 1a du tronçon 1, alors que l'extrémité dudit tapis 15 recouvre totalement les parties en saillie 11 et les creux 12 de l'extrémité 1b dudit tronçon 1.The end 15a of the mat 15 partially covers the protruding parts 11 and the recesses 12 of the end 1a of the section 1, while the end of said mat 15 completely covers the protruding parts 11 and the recesses 12 of the end 1b of said section 1.

De plus, l'extrémité 15b du tapis 15 est profilée. Ainsi, au moment de l'assemblage de deux tronçons opposés, l'extrémité 15b du tapis 15 de l'un des tronçons 1 soulève l'extrémité 15a du tapis 15 de l'autre tronçon, si bien que lesdites extrémités se chevauchent et recouvrent le plan de jointure des deux tronçons.In addition, the end 15b of the mat 15 is profiled. Thus, when two opposite sections are assembled, the end 15b of the mat 15 of one of the sections 1 lifts the end 15a of the mat 15 from the other section, so that said ends overlap and cover the joining plane of the two sections.

Compte-tenu de la simplicité du système selon l'invention, l'assemblage de la travure peut être effectué automatiquement avec rapidité et sûreté et ne nécessite aucune connection avec des dispositifs annexes de fourniture d'énergie par exemple, electrique ou hydraulique.Given the simplicity of the system according to the invention, the assembly of the span can be carried out automatically with speed and safety and does not require any connection with ancillary devices for supplying energy, for example, electric or hydraulic.
