Abstract

comportant un système de bielles nouveau et perfectionné et permettant de meilleurs rendements et performances que les dispositifs connus jusqu'à présent.comprising a new and improved system of connecting rods and allowing better yields and performances than the devices known up to now.

Il permet de réaliser des économies de temps et de main-d'oeuvre et d'effectuer des travaux inaccessibles aux engins munis des dispositifs classiques, notamment grâce à la possibilité d'utiliser les mâchoires séparément.It saves time and labor and makes work inaccessible to machines fitted with conventional devices, in particular thanks to the possibility of using the jaws separately.

Les figures des feuilles de dessin 1 et 3 indiquent les différentes pièces composant le nouveau système, ainsi que leur position lorsque les mâchoires sont fermées ou ouvertes.

Description

Les engins de terrassement utilisés actuellement pour travaux de fouilles et similaires sont munis de mâchoires s'ouvrant et se fermant autour d'un seul axe ou, dans le meilleur des cas, sur deux axes à point fixe. Leur utilisation et leur rendement est donc limité aux mouvements que permettent les dispositifs ci-dessus.The earth-moving machines currently used for excavation work and the like are provided with jaws opening and closing around a single axis or, in the best of cases, on two axes with fixed point. Their use and performance is therefore limited to the movements which the above devices allow.

Le dispositif faisant l'objet de la présente demande de.brevet rend possible non seulement un travail meilleur et plus rapide, mais offre aussi de nouvelles possibilités d'utilisation de l'engin de terrassement; tel qu'exposé dans les revendications, d'où son caractère de nouveauté et d'originalité.The device which is the subject of the present patent application not only makes better and faster work possible, but also offers new possibilities for using the earth-moving machine; as set out in the claims, hence its character of novelty and originality.

Outre les deux mâchoires 1 dont la forme est améliorée, le dispositif comprend : des leviers 2 soudés aux tubes 10, étant chacun solidaire d'une mâchoire; des bielles principales 3 relient les axes 8 soudés sur les ferrures 11, aux axes 9 fixés sur les leviers 2; les vérins à double effet 4 actionnant les leviers 2, ainsi que les bielles principales 3; l'axe de rotation des mâchoires est déplacé latéralement, ce qui confère à l'engin une grande force de préhension; des biellettes 6 reliant les bielles principales 3 à un châssis 5 par lequel l'engin est maintenu et guidé; des leviers 7 stabilisent le châssis 5 au centre de l'appareil dans n'importe quel angle d'ouverture des mâchoires. La machine appropriée à l'emploi de l'engin décrit peut transmettre sa force à l'une ou à l'autre des mâchoires; cette force exercée sur le châssis 5 dans le sens de travail des mâchoires, engendre une réaction simultanée des deux mâchoires. Il en résulte donc une nouvelle possibilité d'application.In addition to the two jaws 1, the shape of which is improved, the device comprises: levers 2 welded to the tubes 10, each being integral with a jaw; main connecting rods 3 connect the axes 8 welded to the fittings 11, to the axes 9 fixed on the levers 2; the double-acting cylinders 4 actuating the levers 2, as well as the main connecting rods 3; the axis of rotation of the jaws is moved laterally, which gives the machine a great grip force; connecting rods 6 connecting the main connecting rods 3 to a frame 5 by which the machine is maintained and guided; levers 7 stabilize the chassis 5 in the center of the device in any angle of opening of the jaws. The machine suitable for the use of the machine described can transmit its force to one or the other of the jaws; this force exerted on the frame 5 in the working direction of the jaws, generates a simultaneous reaction of the two jaws. This therefore results in a new possibility of application.

Les figures des feuilles de dessin ci-jointes indiquent la position des différentes pièces composant le dispositif nouveau pour lequel le brevet est demandé.The figures of the attached drawing sheets indicate the position of the various parts making up the new device for which the patent is applied for.
