Abstract

The device has a bearing (3) fixed at a tilting bucket of a dump lorry, and a thrust bearing (5) comprising a female cusp (7) that is fixed at the tilting bucket. An articulation plate (6) is fixed on a rear door and comprises a male cusp (8) and an articulated rod (4). The bearing comprises an anchoring point (16) for cables that carry a cover of the tilting bucket. The articulation plate comprises a retaining pin (9) for retaining a rear transverse bar that supports a tarpaulin cover (10). A guide ramp (15) guides the transverse bar of the tarpaulin cover towards the retaining pin.

Description

L'invention concerne l'amélioration des systèmes de charnières à double articulation destinés en particulier aux portes arrière des bennes basculantes (1). Ces systèmes se présentent sous la forme de deux ensembles (2) comportant chacun un palier (3), une bielle (4), une butée (5) et une platine d'articulation (6) portant la porte. Les améliorations selon l'invention consistent à intégrer à ces ensembles d'autres fonctionnalités telles que deux redents -mâle (8) et femelle (7) - de verrouillage vertical de la porte, un moyen d'ancrage du câble porteur de la bâche de couverture de la benne (16), un ergot de retenue (9) et une rampe de guidage (15) de la barre d'extrémité de la bâche (10). La double articulation constitue une protection efficace contre les renversements ou les dégradations matérielles consécutifs au plantage de la porte arrière, dans le sol ou dans le chargement, lors du basculement de la benne. Elle consiste à articuler la porte (1) sur deux bielles horizontales (4), elles mêmes articulées sur la benne par l'intermédiaire des paliers (3). Cette disposition permet à la porte (1) de s'effacer verticalement vers le haut lorsqu'un obstacle se présente lors du basculement de la benne (11). En configuration « déplacement » de la benne, l'articulation de la porte et sa translation verticale doivent être verrouillées; à l'inverse, en position « vidage », elles doivent être déverrouillées. Sur ce type de bennes, l'ouverture de la porte arrière s'effectue par gravité lors du basculement de la benne, après déverrouillage des crochets de retenue (12) de la porte et libération du mouvement de translation vertical de la porte. The invention relates to the improvement of the double hinge hinge systems intended in particular for the rear doors of the tippers (1). These systems are in the form of two sets (2) each comprising a bearing (3), a rod (4), a stop (5) and a hinge plate (6) carrying the door. The improvements according to the invention consist in integrating into these sets of other features such as two redents-male (8) and female (7) - vertical locking of the door, a means of anchoring the carrying cable of the tarpaulin. cover of the bucket (16), a retaining pin (9) and a guide ramp (15) of the end bar of the cover (10). The double articulation provides effective protection against spills or material damage following the crash of the rear door, the floor or the load, when tipping the bucket. It consists of articulating the door (1) on two horizontal rods (4), they themselves articulated on the bucket via the bearings (3). This arrangement allows the door (1) to fade vertically upward when an obstacle arises during the tilting of the bucket (11). In "displacement" configuration of the bucket, the articulation of the door and its vertical translation must be locked; conversely, in the "dump" position, they must be unlocked. On this type of bucket, the opening of the rear door is made by gravity when tilting the bucket, after unlocking the retaining hooks (12) of the door and release of the vertical translational movement of the door.

La manoeuvre des deux dispositifs de déverrouillages est donc nécessaire pour permettre l'ouverture de la porte par gravité. Les opérations de verrouillage et déverrouillage des crochets de retenue de porte sont généralement obtenues de façon automatique par le basculement de la benne. Selon l'exemple, le déverrouillage est obtenu par l'action des leviers 30 prolongeant les crochets de retenue (12) articulés sur la benne qui prennent appuis (13) sur le châssis du camion lors du levage et le verrouillage est obtenu par les ressorts (14) lors de la descente de la benne. Les opérations de verrouillage et de déverrouillage du mouvement de translation vertical de porte sont à ce jour obtenues le plus souvent manuellement par 35 des crochets ou goupilles actionnés par le chauffeur qui doit alors quitter son poste de conduite pour y accéder. Leur motorisation par des moyens hydraulique ou électrique est évidemment possible mais coûteuse. La présente invention permet de remédier à ces inconvénients par l'interaction de simples redents, l'un femelle (7) intégré à la butée (5) et l'autre mâle (8), intégré à la platine d'articulation (6), de façon telle que 40 la fermeture de la porte verrouille son mouvement de translation verticale et son ouverture le déverrouille. Par ce moyen, la mise en oeuvre de la benne s'en trouve simplifiée et les interventions du chauffeur dans les opérations de vidage peuvent être évitées. L'optimisation de la conception des blocs selon l'invention permet également 45 d'y intégrer les points d'ancrage (16) des câbles porteurs de la couverture de la benne, les ergots de retenue (9) de la barre de traction de la bâche (10) ainsi que ses rampes de guidage (15), compte tenu de leur situation en extrémité supérieure arrière de la benne. Les dessins annexés illustrent l'invention : 50 La figure 1 représente la vue d'ensemble d'un camion benne. The operation of the two unlocking devices is necessary to allow the door to be opened by gravity. The locking and unlocking operations of the door retaining hooks are generally obtained automatically by tilting the bucket. According to the example, the unlocking is obtained by the action of the levers 30 extending the retaining hooks (12) hinged to the bucket which take supports (13) on the chassis of the truck during lifting and locking is obtained by the springs (14) during the descent of the bucket. The locking and unlocking operations of the vertical door translation movement are currently obtained most often manually by hooks or pins actuated by the driver who must then leave his driving position to access it. Their motorization by hydraulic or electrical means is obviously possible but expensive. The present invention overcomes these disadvantages by the interaction of simple redents, one female (7) integrated with the stop (5) and the other male (8), integrated with the hinge plate (6) such that the closing of the door locks its vertical translational movement and its opening unlocks it. By this means, the implementation of the bucket is simplified and the interventions of the driver in emptying operations can be avoided. Optimizing the design of the blocks according to the invention also makes it possible to integrate the anchoring points (16) of the load-carrying cables of the bucket, the retaining lugs (9) of the drawbar of the bucket. the sheet (10) and its guide ramps (15), given their situation at the rear end of the bucket. The accompanying drawings illustrate the invention: FIG. 1 represents the overall view of a dump truck.

La figure 2 représente le détail d'un ensemble de la double charnière et de la porte arrière. La figure 3 représente la benne en position basculée avec sa porte arrière en butée sur 5 le chargement. Figure 2 shows the detail of an assembly of the double hinge and the rear door. Figure 3 shows the bucket in the tilted position with its rear door abutting the load.
