Description

La présente invention est située dans le domaine technique des ponts fixes ou flottants et plus précisément des moyens d'accrochages de deux éléments de ponts entre eux.The present invention is located in the technical field of fixed or floating bridges and more precisely means for hooking two bridge elements together.

Dans ce domaine, de nombreux dispositifs ont déjà été proposés. Ainsi, on connait du brevet français n° 2 158 618 un dispositif d'assemblage de deux éléments de ponts à clin, c'est-à-dire dans lequel les deux éléments à assembler sont superposés à leur extrémité. Ce dispositif comporte un boulet suspendu à une chaine moufflée pour assembler les deux éléments ainsi que des pions sphériques de centrage fixes et en saillie s'engageant dans des entonnoirs. Le verrouillage s'effectue par un ensemble annexe de crochets actionnés par des vérins.Many devices have already been proposed in this area. Thus, there is known from French patent No. 2 158 618 a device for assembling two clapboard bridge elements, that is to say in which the two elements to be assembled are superimposed at their ends. This device comprises a ball suspended from a muffled chain to assemble the two elements as well as spherical pins for centering fixed and projecting engaging in funnels. Locking is effected by an annex set of hooks actuated by jacks.

Ce dispositif a pour fonction principale de prendre et de déposer un élément de pont et nécessite une intervention manuelle pour la mise en place des boulets de préhension. Dans certains cas d'utilisation, les pions de centrage ne s'effaçant pas peuvent être soumis à des déteriorations.The main function of this device is to pick up and drop off a bridge element and requires manual intervention for the positioning of the gripping balls. In certain cases of use, the centering pins which do not erase may be subject to deterioration.

Le brevet allemand n° 1 124 383 décrit un dispositif d'assemblage de deux éléments de pont bout à bout et nécessite une opération manuelle de mise en place des crochets de verrouillage.German patent n ° 1 124 383 describes a device for assembling two bridge elements end to end and requires a manual operation of fitting the locking hooks.

On connait également d'autres dispositifs utilisés sur des engins de franchissement.Other devices are also known to be used on crossing machines.

Mais tous ces dispositifs comportent suivant les types des étriers, des fourchettes, des crochets, des broches mécaniques ou hydrauliques servant à la fois d'assembleur et de verrouilleur.But all these devices include, depending on the types of stirrups, forks, hooks, mechanical or hydraulic spindles serving both as an assembler and as a locker.

Ces dispositifs ne sont pas toujours protégés des salissures et sont parfois soumis à des détériorations importantes lors du passage des véhicules. Ces problèmes rendent difficiles les opérations de déverrouillage et de désassemblage des éléments de ponts. En outre, la plupart de ces dispositifs ne se mettent en place que manuellement, certains étant toutefois semi-automatiques.These devices are not always protected from dirt and are sometimes subject to significant deterioration during the passage of vehicles. These problems make it difficult to unlock and disassemble the bridge elements. In addition, most of these devices are only installed manually, some being semi-automatic, however.

Le brevet français n° 1 592 501 montre, dans un mode de réalisation, des travures de véhicules amphibies utilisées indépendamment des véhicules comme éléments de pont flottant. Toutefois ces travures doivent être accouplées en respectant un sens d'accouplement puisque seule une extrémité de la travure possède un élément d'accouplement sur sa partie supérieure tandis que l'autre extrémité possède un élément d'accouplement sur sa partie inférieure. De ce fait, l'accrochage de deux éléments en est compliqué puisque si un élément est présenté à l'envers, il doit d'abord être retourné avant de pouvoir être accroché à un second élément.French patent No. 1,592,501 shows, in one embodiment, spans of amphibious vehicles used independently of the vehicles as floating bridge elements. However, these spans must be coupled respecting a direction of coupling since only one end of the span has a coupling element on its upper part while the other end has a coupling element on its lower part. As a result, the attachment of two elements is complicated since if an element is presented upside down, it must first be turned over before it can be hung on a second element.

Un des buts de la présente invention est de fournir un dispositif d'accrochage permettant de tenir assemblés et verrouillés l'un sur l'autre des éléments de pont (assemblage dit à clin) tels que: passerelles, travures, rampes à partir de supports fixes ou flottants afin de réaliser un ouvrage permettant de faire franchir n'importe quel type de brèche par des véhicules, tout en évitant les inconvénients présentés par les dispositifs antérieurs.One of the aims of the present invention is to provide a hooking device making it possible to hold assembled and locked one on the other bridge elements (assembly called clapboard) such as: gangways, spans, ramps from supports fixed or floating in order to produce a structure making it possible to clear any type of breach by vehicles, while avoiding the drawbacks presented by the prior devices.

Un autre but de l'invention est de réduire les délais de mise en oeuvre d'un pont par la mise en place d'un verrouillage automatique après assemblage.Another object of the invention is to reduce the implementation times of a bridge by the installation of an automatic locking after assembly.

L'invention a également pour but d'assurer la continuité du chemin de roulement formé par les différents éléments assemblés ainsi que de permettre l'assemblage d'éléments tous identiques et sans particularisation.The invention also aims to ensure the continuity of the raceway formed by the various assembled elements as well as to allow the assembly of elements all identical and without particularization.

Un autre but de l'invention est de permettre l'assemblage à clin, c'est-à-dire par superposition des extrémités des éléments, soit sur l'extrados d'un élément, soit sur son extrados selon les circonstances et ceci, sans avoir à modifier ou à adapter chaque élément selon le positionnement choisi.Another object of the invention is to allow blunt assembly, that is to say by superposition of the ends of the elements, either on the upper surface of an element, or on its upper surface depending on the circumstances and this, without having to modify or adapt each element according to the chosen positioning.

L'invention a donc pour objet un dispositif automatique d'assemblage à clin de deux éléments de pont flottants sur intrados ou sur extrados l'élément de pont inférieur pouvant devenir élément supérieur et réciproquement au moyen de doigts verrouillables caractérisé en ce qu'un premier élément de pont comporte un ensemble transversal de doigts mobiles d'une première position où ils sont effacés dans le corps de l'élément de pont, vers deux secondes positions où les doigts sont en saillie soit sur l'intrados soit sur l'extrados et en ce que le second élément de pont comporte des alésages débouchant de part en part sur son intrados et sur son extrados, destinés à recevoir les doigts de centrage du premier élément et en combinaison un ensemble de verrous pour bloquer les doigts du premier élément dans la position d'assemblage, et en ce que les doigts mobiles du premier élément sont solidaires d'un arbre perpendiculaire à l'axe longitudinal de l'élément de pont et mobile en rotation sous l'action d'un moteur pour amener les doigts de leur première position vers une des deux positions de verrouillage.The subject of the invention is therefore an automatic device for the lap joint assembly of two floating bridge elements on the lower or upper surface the lower bridge element which can become an upper element and vice versa by means of locking fingers characterized in that a first bridge element comprises a transverse assembly of movable fingers from a first position where they are erased in the body of the bridge element, towards two second positions where the fingers protrude either on the lower surface or on the upper surface and in that the second bridge element has bores opening right through on its lower surface and on its upper surface, intended to receive the centering fingers of the first element and in combination a set of latches to block the fingers of the first element in the assembly position, and in that the movable fingers of the first element are integral with a shaft perpendicular to the longitudinal axis of the bridge element and movable in rotation under the action of a motor to bring the fingers from their first position to one of the two locking positions.

Selon l'invention, les verrous du second élément sont disposés à l'intérieur de la section de l'élément de pont de telle façon que les pions de verrouillage traversent après assemblage, des alésages pratiqués dans les doigts de centrage.According to the invention, the latches of the second element are arranged inside the section of the bridge element in such a way that the locking pins pass, after assembly, through the bores made in the centering fingers.

Selon une variante d'exécution, les doigts de centrage ont leur extrémité tronconiques, les alésages du second élément ayant une forme biconi- que évasée vers l'extrados et l'intrados pour favoriser le centrage.According to an alternative embodiment, the centering fingers have their frustoconical end, the bores of the second element having a biconical shape flared towards the upper surface and the lower surface to promote centering.

L'invention a également pour objet un élément de pont comportant un dispositif d'assemblage tel que décrit plus haut et comprenant à une de ses extrémités au moins un ensemble de doigts de centrage disposé perpendiculairement à son axe longitudinal et à son extrémité opposée au moins un ensemble d'alésages débouchant de part en part de l'intrados et de l'extrados de l'élément.The invention also relates to a bridge element comprising an assembly device as described above and comprising at one of its ends at least one set of centering fingers disposed perpendicular to its longitudinal axis and at least at its opposite end. a set of bores opening right through the lower surface and the upper surface of the element.

L'invention sera mieux comprise à la lumière du complément de description qui va suivre en référence aux dessins annexés, lesquels représentent:The invention will be better understood in the light of the additional description which follows with reference to the appended drawings, which represent:

la figure 1 une coupe longitudinale de l'extrémité de deux éléments de ponts assemblés et incluant deux variantes de forme des doigts de centrage.Figure 1 a longitudinal section of the end mite of two assembled bridge elements and including two variants of shape of the centering fingers.

La figure 2, deux demi-coupes suivant AA et BB de la figure 1 perpendiculaires à l'axe longitudinal des éléments en cours d'assemblage et montrant les deux variantes de la figure 1.FIG. 2, two half-sections along AA and BB of FIG. 1 perpendicular to the longitudinal axis of the elements being assembled and showing the two variants of FIG. 1.

Ainsi qu'on le voit à la figure 1 les deux éléments C et D sont disposés à clin, l'élément C comporte deux rangées de doigts 1 et 2 disposés selon un axe perpendiculaire à l'axe longitudinal des éléments de pont. Les doigts de centrage et de verrouillage 1 et 2 sont portés par deux arbres 3 et 4 montés sur palier 3' et 4' dans l'âme de l'élément C et rendus mobiles en rotation au moyen de moteurs 5 et 6 commandé par tout moyen approprié.As can be seen in FIG. 1, the two elements C and D are arranged in the blink of an eye, the element C comprises two rows of fingers 1 and 2 arranged along an axis perpendicular to the longitudinal axis of the bridge elements. The centering and locking fingers 1 and 2 are carried by two shafts 3 and 4 mounted on bearings 3 'and 4' in the core of the element C and made mobile in rotation by means of motors 5 and 6 controlled by any appropriate means.

Les moteurs 5 et 6 peuvent être à double sens de rotation ou posséder sur l'arbre de sortie un inverseur de marche de telle sorte que les doigts 1 et 2 puissent se déplacer de leur position de repos 7 à l'intérieur des éléments C et D jusqu'à une position d'assemblage, soit sur l'intrados ainsi que sont représentés à la figure 1 en traits pleins les doigts 1 et 2 soit sur l'extrados (position 1' et 2' représentés en traits discontinus) pour un montage inverse des éléments C et D.The motors 5 and 6 can have a double direction of rotation or have a reverse gear on the output shaft so that the fingers 1 and 2 can move from their rest position 7 inside the elements C and D to an assembly position, either on the lower surface as shown in Figure 1 in solid lines fingers 1 and 2 or on the upper surface (position 1 'and 2' shown in broken lines) for a reverse assembly of elements C and D.

Les doigts 1 sont munis d'alésages 8 coopérant avec les verrous de l'élément D qui seront ultérieurement décrits et les doigts 2 dans une variante de réalisation possèdent deux alésages 9 et 10.The fingers 1 are provided with bores 8 cooperating with the locks of the element D which will be described later and the fingers 2 in an alternative embodiment have two bores 9 and 10.

L'élément D comporte deux rangées de verrous 11 et 12 coopérant avec les doigts 1 et 2. Ces verrous possèdent soit un pion de verrouillage 13 (pour les verrous 11) soit deux pions de verrouillage 14 et 15 (pour les verrous 12) manoeuvrables de façon automatique par tout moyen approprié.Element D has two rows of latches 11 and 12 cooperating with fingers 1 and 2. These latches have either a locking pin 13 (for the latches 11) or two locking pins 14 and 15 (for the latches 12) which can be operated automatically by any appropriate means.

Les verrous sont disposés de façon telle qu'ils débouchent dans des alésages 16 et 17 destinés à recevoir les doigts 1 et 2.The locks are arranged in such a way that they open into bores 16 and 17 intended to receive the fingers 1 and 2.

Selon la forme des doigts (cylindrique pour le doigt 11 et conique pour le doigt 12) les alésages 16 seront cylindriques et comporteront un chanfrein de centrage 18 ou biconiques (alésages 17) de façon à assurer un positionnement parfait des éléments l'un rapport à l'autre.Depending on the shape of the fingers (cylindrical for finger 11 and conical for finger 12) the bores 16 will be cylindrical and will include a centering chamfer 18 or biconical (bores 17) so as to ensure perfect positioning of the elements in relation to the other.

Pour assembler les éléments C et D, on actionne les doigts 1 et 2 dans le sens convenable selon le positionnement chiosi pour les éléments. On pose ensuite les éléments à clin, les doigts 1 et 2 assurant le centrage correct des travures. Lorsque la travure C repose sur D, on actionne les verrous 11 et 12. Les doigts 13, 14 et 15 se positionnent alors dans les alésages 8, 9 et 10 assurant ainsi le maintien de l'assemblage des deux éléments.To assemble the elements C and D, the fingers 1 and 2 are actuated in the proper direction according to the positioning chosen for the elements. The clapboard elements are then placed, fingers 1 and 2 ensuring the correct centering of the spans. When the span C rests on D, the latches 11 and 12 are actuated. The fingers 13, 14 and 15 are then positioned in the bores 8, 9 and 10 thus ensuring the maintenance of the assembly of the two elements.

On pourra dimensionner judicieusement les doigts 13, 14 et 15 de façon que lors du verrouillage, leur longueur soit suffisamment grande pour traverser les doigts 1 et 2 et reposer dans des paliers 19, 20 et 21 de façon à faire participer à la tenue aux efforts, la travure elle-même.The fingers 13, 14 and 15 can be suitably sized so that during locking, their length is large enough to pass through the fingers 1 and 2 and rest in bearings 19, 20 and 21 so as to participate in the resistance to the forces , the span itself.

Un élément de pont selon l'invention pourra comprendre à une de ses extrémités une ou plusieurs rangées de doigts de centrage 1 ou/et 2 tandis que son autre extrémité comprendra des verrous 11 ou/et 12, la seule exigence de montage étant de posséder un même nombre de rangée de verrous que de doigts correspondants.A bridge element according to the invention may comprise at one of its ends one or more rows of centering fingers 1 or / and 2 while its other end will include latches 11 or / and 12, the only mounting requirement being to have the same number of rows of locks as corresponding fingers.

Ainsi le montage d'un pont s'effectue simplement à l'aide d'éléments tous identiques que l'on peut disposer au choix soit en position supérieure soit en position inférieure sans aucun problème d'adaptation.Thus the assembly of a bridge is carried out simply using all identical elements which can be arranged either in the upper position or in the lower position without any problem of adaptation.

L'invention s'applique donc avantageusement à la réalisation de ponts de toutes longueurs.The invention therefore advantageously applies to the production of bridges of all lengths.
