Description
TITRE : Dispositif de réglage d'un outil fixé à l'extrémité du bras d'une pelle ou analogue TITLE: Device for adjusting a tool attached to the end of the arm of a shovel or the like
La présente invention est relative à un dispositif de réglage d'un outil fixé à l'extrémité du bras d'une pelle ou analogue.The present invention relates to a device for adjusting a tool fixed to the end of the arm of a shovel or the like.
Le bras d'une pelle est mobile dans un plan vertical et l'outil qu'il porte est mobile autour d'un axe perpendiculaire audit plan. Ainsi, par exemple, si l'outil est un brise-roche l'axe de sa pointe perforatrice est mobile, uniquement, dans le plan vertical précité.The arm of a shovel is movable in a vertical plane and the tool which it carries is movable around an axis perpendicular to said plane. Thus, for example, if the tool is a rock breaker, the axis of its perforating point is movable only in the above-mentioned vertical plane.
Pour certains travaux, il est nécessaire que l'axe de rotation de l'outil soit disposé obliquement par rapport au plan vertical. C'est le cas lorsque, par exemple, il faut briser un rocher faisant sailli hors d'une des parois latérales d'une tranchée. Dans ce cas, l'axe de la pointe perforatrice doit être incliné par rapport à ladite paroi.For some works, it is necessary that the axis of rotation of the tool is arranged obliquely to the vertical plane. This is the case when, for example, it is necessary to break a rock protruding from one of the side walls of a trench. In this case, the axis of the perforating tip must be inclined relative to said wall.
Il existe des dispositifs permettant d'atteindre ce résultat, mais ceux-ci font appel à des moyens compliqués utilisant des vérins hydrauliques. Ces moyens ne peuvent pas êtres utilisés lorsque la fixation de l'outil au bras de la pelle s'effectue par l'entremise d'une attache rapide qui, comme on le sait, est un dispositif, interposé entre le bras et l'outil, permettant la fixation dudit outil par une manœuvre du bras et, ce, sans que le conducteur de l'engin soit obligé de descendre de ce dernier.There are devices to achieve this result, but these use complicated means using hydraulic cylinders. These means cannot be used when the attachment of the tool to the arm of the shovel is effected by means of a quick coupler which, as we know, is a device, interposed between the arm and the tool , allowing the attachment of said tool by maneuvering the arm, without the operator of the machine being forced to get off the latter.
De plus, comme l'utilisation de vérins implique, toujours, le raccordement de canalisations à une source de fluide sous pression, la présence de ces derniers rendrait sans intérêt l'utilisation d'une attache rapide dont la complexité s'en trouverait, néanmoins, augmentée. Le dispositif de l'invention, qui remédie à ces inconvénients, est remarquable en ce que l'outil est porté par un arbre, dont l'axe est mobile dans le plan du bras, ledit outil pouvant être déplacé axialement par rapport audit arbre, à encontre de l'action d'un ressort antagoniste, et pivoter autour dudit axe, des moyens étant prévus pour verrouiller, automatiquement l'outil selon l'inclination requise.In addition, as the use of cylinders always involves the connection of pipes to a source of pressurized fluid, the presence of the latter would make the use of a quick coupler, the complexity of which would be found, however, , increased. The device of the invention, which overcomes these drawbacks, is remarkable in that the tool is carried by a shaft, the axis of which is movable in the plane of the arm, said tool being able to be moved axially relative to said shaft, against the action of an opposing spring, and pivot about said axis, means being provided for locking, automatically the tool according to the required inclination.
Selon un mode de réalisation, le dispositif de l'invention, comporte deux étriers dont l'un est rendu solidaire du support pivotant usuel du bras tandis que l'autre est rendu solidaire de l'outil, les branches des deux étriers étant imbriquées et traversées par un arbre, fixe par rapport à l'un desdits étriers, qui sont soumis à l'action d'un ressort tendant à déplacer un étrier par rapport à l'autre de façon à faire coopérer les deux parties d'un organe de verrouillage qui maintient l'outil selon l'inclinaison requise.According to one embodiment, the device of the invention comprises two stirrups, one of which is made integral with the usual pivoting support of the arm while the other is made integral with the tool, the branches of the two stirrups being nested and crossed by a shaft, fixed relative to one of said stirrups, which are subjected to the action of a spring tending to move one stirrup relative to the other so as to make the two parts of a member of cooperation cooperate lock that holds the tool at the required tilt.
Dans le cas où l'outil est fixé au bras par l'entremise d'une attache rapide, le dispositif de l'invention est interposé entre l'outil et l'adaptateur de l'attache rapide, l'une des deux parties, de l'attache, normalement fixée à l'outil.In the case where the tool is fixed to the arm by means of a quick coupler, the device of the invention is interposed between the tool and the adapter of the quick coupler, one of the two parts, the clip, normally attached to the tool.
La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif, seulement, sur lesquels : -la figure 1 montre en élévation un brise-roche fixé à l'extrémité du bras d'un engin par l'entremise du dispositif de l'invention ;The present invention will be better understood from the description which follows made with reference to the accompanying drawings by way of indicative example only, in which: FIG. 1 shows in elevation a rock breaker fixed to the end of the arm d 'a machine through the device of the invention;

-la figure 9 est la vue de dessus de la figure 8 ;FIG. 9 is the top view of FIG. 8;
-la figure 10 est une vue analogue à la figure 8 montrant la position du bras et de l'outil à la fin du réglage de l'inclinaison ;FIG. 10 is a view similar to FIG. 8 showing the position of the arm and of the tool at the end of the adjustment of the inclination;
-la figure 11 est la vue de dessus de la figure 10.FIG. 11 is the top view of FIG. 10.
En se reportant à la figure 1 , on voit que l'outil B, en l'espèce un brise- roche, est fixé à l'extrémité du bras 1 par l'entremise du support pivotant 2 articulé par l'arbre 3 sur ledit bras. De la façon connue, le bras 1 peut être déplacé dans le plan vertical (plan de la figure 1). La manœuvre du bras 1 permet donc de déplacer l'outil et notamment l'axe XXi dans le plan vertical.Referring to FIG. 1, it can be seen that the tool B, in this case a rock breaker, is fixed to the end of the arm 1 by means of the pivoting support 2 articulated by the shaft 3 on the said arms. In known manner, the arm 1 can be moved in the vertical plane (plane of Figure 1). The operation of the arm 1 therefore makes it possible to move the tool and in particular the axis XXi in the vertical plane.
Le problème posé consiste à prévoir un ensemble de moyens permettant de placer l'axe XXi selon une position oblique par rapport au plan vertical, de le maintenir dans cette position, de modifier l'inclinaison et, ce, sans que le conducteur ne descende de l'engin. Selon l'invention, l'outil est articulé sur un arbre 4, porté par le supportThe problem posed consists in providing a set of means making it possible to place the axis XXi in an oblique position relative to the vertical plane, to maintain it in this position, to modify the inclination and this, without the driver descending from the craft. According to the invention, the tool is articulated on a shaft 4, carried by the support
2 et disposé dans le plan du bras 1 , ledit outil pouvant être déplacé selon l'axe dudit arbre à encontre de l'action d'un ressort 5 antagoniste de façon à le déverrouiller et à permettre sa rotation, cette dernière ayant pour effet de placer l'axe XXi selon une direction oblique par rapport au plan vertical.2 and arranged in the plane of the arm 1, the said tool being able to be displaced along the axis of the said shaft against the action of an opposing spring 5 so as to unlock it and allow its rotation, the latter having the effect of place the axis XXi in an oblique direction relative to the vertical plane.
Selon un mode de réalisation, l'arbre 4 traverse les ailes 6-6a et 7-7a de deux étriers dont la partie médiane 8 de l'un est fixée au support 2 tandis que celle 9 de l'autre est fixée à l'outil B. Par la suite, les étriers seront dénommés : étrier 8 et étrier 9.According to one embodiment, the shaft 4 crosses the wings 6-6a and 7-7a of two stirrups, the middle part 8 of one of which is fixed to the support 2 while that 9 of the other is fixed to the tool B. Thereafter, the stirrups will be called: stirrup 8 and stirrup 9.
Les ailes 6-6a et 7-7a sont imbriquées et l'arbre 4 est rendu solidaire de l'aile 6a.The wings 6-6a and 7-7a are nested and the shaft 4 is made integral with the wing 6a.
Le ressort 5 est interposé entre les ailes 6 et 7a, ou ailes internes, et tend à plaquer l'une contre l'autre les ailes correspondantes des étriers 8 et 9 comme montré, notamment sur la figure 2.The spring 5 is interposed between the wings 6 and 7a, or internal wings, and tends to press one against the other the corresponding wings of the stirrups 8 and 9 as shown, in particular in FIG. 2.
Dans cette position, le ressort 5 assure la coopération des organes d'un moyen de verrouillage s'opposant à la rotation de l'etrier 9. Si par une force extérieure on déplace l'un des étriers par rapport à l'autre selon l'axe de l'arbre 4, le verrouillage précité est supprimé et l'outil peut pivoter.In this position, the spring 5 ensures the cooperation of the members of a locking means opposing the rotation of the stirrup 9. If by an external force one of the stirrups is displaced relative to the other according to the 'axis of the shaft 4, the aforementioned locking is removed and the tool can pivot.
Le moyen de verrouillage, précité est constitué par un crabot, disposé selon l'axe de l'arbre 4, dont une partie 10 est constituée, par exemple, au moyen d'un pignon fixe, porté par l'etrier 8, susceptible d'engrener avec une couronne 11 à denture interne portée par l'etrier 9. Un fourreau 12, monté sur l'arbre 4 et interposé entre les ailes 7a et 6, limite le déplacement d'un étrier par rapport à l'autre.The aforementioned locking means is constituted by a dog clutch, arranged along the axis of the shaft 4, part of which 10 is constituted, for example, by means of a fixed pinion, carried by the caliper 8, capable of '' mesh with a crown 11 with internal toothing carried by the caliper 9. A sheath 12, mounted on the shaft 4 and interposed between the wings 7a and 6, limits the movement of one stirrup relative to the other.
Le dispositif qui vient d'être décrit ci-dessus est actionné par des manœuvres judicieuses du bras et de l'outil commandées par le conducteur à partir de la cabine de l'engin comme cela ressort des figures 8 à 11 qui illustrent le fonctionnement.The device which has just been described above is actuated by judicious maneuvers of the arm and of the tool controlled by the driver from the cabin of the machine as shown in FIGS. 8 to 11 which illustrate the operation.
Si on veut modifier l'inclinaison de l'axe de l'outil, on pose celui-ci au sol comme montré sur la figure 8 ce qui a pour effet de placer l'axe de l'arbre 4, sensiblement verticalement, dans le plan vertical contenant le bras.If we want to modify the inclination of the axis of the tool, we put it on the ground as shown in Figure 8 which has the effect of placing the axis of the shaft 4, substantially vertically, in the vertical plane containing the arm.
Si, à partir de cette position, on fait pivoter le bras 1 selon la flèche Fi, on repousse l'etrier 8 vers le sol en comprimant le ressort 5 ce qui entraîne le déverrouillage du crabot10-11 , les deux étriers occupant alors la position représentée sur la figure 4.If, from this position, the arm 1 is made to pivot according to the arrow Fi, the caliper 8 is pushed back towards the ground by compressing the spring 5 which causes the clutch dog to unlock10-10, the two calipers then occupying the position shown in figure 4.
A ce moment, il suffit de maintenir la pression sur le bras et de le faire pivoter autour de son axe vertical 13 (fig.11) ce qui a pour effet de faire pivoter l'outil autour de l'axe de l'arbre 4.At this time, it suffices to maintain the pressure on the arm and to rotate it around its vertical axis 13 (fig.11) which has the effect of rotating the tool around the axis of the shaft 4 .
En relâchant l'action sur le bras, le ressort se détend et le pignon 10 engrène de nouveau avec la couronne 11 en maintenant l'axe de l'outil selon une position inclinée par rapport au plan vertical contenant le bras 1.By releasing the action on the arm, the spring relaxes and the pinion 10 meshes again with the crown 11 while maintaining the axis of the tool in an inclined position relative to the vertical plane containing the arm 1.
L'invention prévoit aussi un moyen pour s'opposer, de façon positive, au déplacement des étriers lorsque l'outil est en position normale de travail telle que montrée sur la figure 1 par exemple. Ce moyen va être décrit en regard des figures 5 à 7. Il est essentiellement constitué par un doigt pivotant 14, articulé par l'une de ses extrémités sur l'etrier 8, par l'entremise d'un arbre 15, et dont l'autre s'étend jusqu'à proximité de l'aile 7a de l'etrier lorsque l'outil est dans sa position normale d'utilisation. Comme montré, notamment sur la figure 5, des moyens, tels qu'une butée 16, sont prévus pour limiter le pivotement du doigt 14.The invention also provides a means for opposing, in a positive manner, the movement of the stirrups when the tool is in the normal working position as shown in FIG. 1 for example. This means will be described with reference to FIGS. 5 to 7. It essentially consists of a pivoting finger 14, articulated by one of its ends on the stirrup 8, by means of a shaft 15, and the l 'other extends to near the wing 7a of the caliper when the tool is in its normal position of use. As shown, in particular in FIG. 5, means, such as a stop 16, are provided to limit the pivoting of the finger 14.
Lorsqu'on place l'outil dans la position qui permet le déverrouillage du crabot, le doigt 14 pivote et occupe alors la position représentée sur la figure 7 et ne s'oppose plus à la compression du ressort 5.When the tool is placed in the position which allows the clutch to be unlocked, the finger 14 pivots and then occupies the position shown in FIG. 7 and no longer opposes the compression of the spring 5.
Le dispositif de l'invention est parfaitement compatible avec l'utilisation d'une attache rapide, pour cela il suffit de l'interposer entre l'outil et l'adaptateur de l'attache rapide. Les figures 8 à 11 illustrent cette possibilité. The device of the invention is perfectly compatible with the use of a quick coupler, for this it is sufficient to interpose it between the tool and the adapter of the quick coupler. Figures 8 to 11 illustrate this possibility.
