Abstract
L'INVENTION CONCERNE UNE FLECHE DE PELLE MECANIQUE. SELON L'INVENTION, LA PARTIE SUPERIEURE 2 MONTEE SUR LA PARTIE INFERIEURE 1 DE FACON A POUVOIR TOURNER, EST RELIEE A LA PARTIE TOURNANTE 7 DE L'ENGIN, DES DEUX COTES DE L'AXE DE ROTATION 3, PAR L'INTERMEDIAIRE DE DEUX AXES 4A, 4B D'APPLICATION DES FORCES, PAR UN ELEMENT DE REGLAGE 5 DE LONGUEUR VARIABLE ET UNE PIECE D'ECARTEMENT 6 DE LONGUEUR CONSTANTE. APPLICATION A LA FABRICATION DE FLECHES DE PELLES MECANIQUES.THE INVENTION RELATES TO A MECHANICAL SHOVEL ARROW. ACCORDING TO THE INVENTION, THE UPPER PART 2 MOUNTED ON THE LOWER PART 1 TO BE ABLE TO TURN, IS CONNECTED TO THE TURNING PART 7 OF THE MACHINE, ON BOTH SIDES OF THE ROTATION AXIS 3, THROUGH TWO AXES 4A, 4B FOR THE APPLICATION OF FORCES, BY AN ADJUSTING ELEMENT 5 OF VARIABLE LENGTH AND A SPACING PART 6 OF CONSTANT LENGTH. APPLICATION TO THE MANUFACTURE OF ARROWS FOR MECHANICAL SHOVELS.
Description
L'invention porte sur une flèche pour pelle mécanique.The invention relates to an arrow for excavator.
Le but de l'invention est d'obtenir à peu de frais, pour une flèche constituée par une partie supérieure et une partie inférieure, une régularisation des variations-du moment The object of the invention is to obtain inexpensively, for an arrow constituted by an upper part and a lower part, a regularization of the variations of the moment

trêmes, tout en augmentant la plage d'angles de travail L'in- vention vise notamment à obtenir une position finale aussi haute que possible de la partie supérieure en partant d'un certain plan de travail inférieur déterminé Ce but est atteint du fait que la partie supérieure de la flèche, montée sur la î O partie inférieure de façon à pouvoir tourner, est reliée à la The invention aims, in particular, at obtaining a final position as high as possible from the upper part, starting from a certain determined lower working plane. This goal is achieved by the fact that the upper part of the boom, mounted on the lower part so as to be rotatable, is connected to the

La figure 1 représente un équipement de base. Figure 1 shows basic equipment.
La figure 2 représente un équipement de pelle mécani- Figure 2 shows a mechanical excavator equipment
que avec lequel une flèche d'équipement pourvue d'organes de with which an equipment arrow with
commande est montée sur la partie supérieure de la flèche. control is mounted on the upper part of the boom.
La figure l montre que la partie supérieure de la flèche montée sur la partie inférieure 1 de façon à pouvoir FIG. 1 shows that the upper part of the arrow mounted on the lower part 1 so as to be able to
tourner est reliée à la partie tournante 7 de la pelle mécani- turn is connected to the rotating part 7 of the excavator

d'un élément d'écartement 6 de longueur constante. a spacer element 6 of constant length.
L'articulation, décrite plus haut, de la partie su- The articulation, described above, of the part above
périeure 2 de la flèche à la partie tournante 7 de la pelle mécanique par l'intermédiaire de l'élément decommande 5 et de l'élément d'écartement 6 permet, suivant la position choisie pour les axes 4 a et 4 b d'application des forces par rapport à l'axe de rotation 3 et compte tenu des distances séparant les axes d'articulation 8 a et 8 b de l'axe de pivotement 9 de la partie inférieure de la flèche, de commander les variations 2 of the arrow at the rotating part 7 of the excavator via the control element 5 and the spacer 6 allows, according to the position chosen for the axes 4 and 4 b of application forces relative to the axis of rotation 3 and taking into account the distances separating the hinge pins 8a and 8b from the pivot axis 9 of the lower part of the boom, to control the variations
du moment de la flèche dans sa zone de pivotement. the moment of the arrow in its pivot zone.
La figure montre en outre que, en partant d'un niveau de travail inférieur d'un point d'articulation 10 de la charge, ce point ne se déplace pas sur une trajectoire circulaire quand la flèche est relevée, mais qu'il atteint un niveau plus élevé, par rapport à la trajectoire circulaire, dans la zone supérieure, et donc qu'un certain allongement se produit Cela permet de charger aisément même des véhicules de transport de grandes dimensions Un autre avantage est que cela peut se faire à proximité immédiate de la pelle mécanique On a ainsi une bonne vue d'ensemble et donc un maniement facile de l'engin Enfin, The figure further shows that, starting from a lower work level of a point of articulation 10 of the load, this point does not move on a circular trajectory when the arrow is raised, but reaches a higher level, compared to the circular path, in the upper zone, and therefore a certain elongation occurs This allows to easily load even large transport vehicles Another advantage is that it can be done in the immediate vicinity the shovel So we have a good overview and therefore easy handling of the machine Finally,
il faut souligner que, avec la flèche en deux éléments, l'opé- it should be emphasized that, with the arrow in two elements, the
ration de travail et l'extension se font au moyen d'un seul ration of work and extension are done by means of a single
