Description

L'invention a pour objet un dispositif de fixation d'un outil sur un engin, notamment un engin de chantier ou agricole. Il existe ac­tuellement sur le marché une série d'engins de chantier d'excavation ou d'enlèvement de matériaux, tels que des excavateurs, des chargeurs, des pelles rétro, etc. Lors de l'utilisation de tels engins, on est amené à changer d'outils, tels que pelle, godet, défonceuse, etc. Des engins modernes comportent des dispositifs automatiques permettant de changer rapidement d'outils. Ces dispositifs ne fonctionnent que pour des outils adaptés ce qui, si l'on veut transformer un engin ancien en un engin permettant le changement automatique de l'outil, implique un changement de tous les outils.The subject of the invention is a device for attaching a tool to a machine, in particular a construction or agricultural machine. There is currently a series of excavation or material removal equipment on the market, such as excavators, loaders, backhoes, etc. When using such devices, you have to change tools, such as shovel, bucket, router, etc. Modern machines have automatic devices for quickly changing tools. These devices only work for suitable tools which, if we want to transform an old machine into a machine allowing the automatic change of the tool, implies a change of all the tools.

L'invention a pour but de fournir un dispositif de fixation d'un outil sur un engin, qui peut être adapté sur tout engin sans changement des outils.The object of the invention is to provide a device for fixing a tool to a machine, which can be adapted to any machine without changing the tools.

Ce but est atteint avec le dispositif défini à la revendication 1.This object is achieved with the device defined in claim 1.

L'invention sera mieux comprise à la lecture de la description d'une forme d'exécution avec référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en plan d'un élément mâle,
  • la figure 2 est une vue en plan d'un élément femelle,
  • la figure 3 est une coupe d'un dispositif selon l'invention assemblé comportant un élément mâle et un élément femelle,
  • la figure 4 est une vue latérale d'un élément mâle,
  • la figure 5 est une vue schématique montrant le dispositif monté sur le bras d'une pelle rétro.
The invention will be better understood on reading the description of an embodiment with reference to the accompanying drawings in which:
  • FIG. 1 is a plan view of a male element,
  • FIG. 2 is a plan view of a female element,
  • FIG. 3 is a section through a device according to the invention assembled comprising a male element and a female element,
  • FIG. 4 is a side view of a male element,
  • Figure 5 is a schematic view showing the device mounted on the arm of a backhoe.

Pour donner une idée générale d'un dispositif selon l'invention, la figure 5 représente l'extrémité d'un bras 25 d'une pelle rétro compre­ nant un tel dispositif. Bien que l'invention soit décrite pour un godet 26, il est clair qu'elle peut être utilisée pour tout outil destiné à être fixé sur le bras d'un engin de chantier ou autre engin.To give a general idea of a device according to the invention, FIG. 5 represents the end of an arm 25 of a backhoe nant such a device. Although the invention is described for a bucket 26, it is clear that it can be used for any tool intended to be fixed on the arm of a construction machine or other machine.

Comme on le voit sur la figure 5, le bras 25 de l'engin comporte deux bielles 27 articulées sur le bras. Entre ces bielles viennent s'articuler la tige 24 d'un vérin de commande (pas représenté) et un organe de liaison 28. Habituellement, le godet 26 est articulé au point 20 sur le bras et au point 19 sur l'organe de liaison 28. Ce qui pour changer le godet 26,nécessite de devoir enlever les axes 19 et 20. Ce système est remplacé par un dispositif selon l'invention de la manière suivante :
- Un élément femelle 9 est fixé sur le bras 25 de l'engin articulé sur l'axe 25 existant et est fixé articulé à l'organe de liaison 28. Cette manière de faire ne nécessite aucune modification de l'engin. Cet élément femelle est fixé à demeure sur l'engin.
- Un élément mâle 1 est fixé à demeure sur le godet 26 par des boulons dans les trous de fixation existant 17 et 18.
- Un élément mâle 1 est fixé à demeure sur tous les outils constituant la série d'outils destinés à être utilisés avec l'engin.
As can be seen in FIG. 5, the arm 25 of the machine comprises two connecting rods 27 articulated on the arm. Between these connecting rods are articulated the rod 24 of a control cylinder (not shown) and a connecting member 28. Usually, the bucket 26 is articulated at point 20 on the arm and at point 19 on the connecting member 28. Which, in order to change the bucket 26, requires having to remove the pins 19 and 20. This system is replaced by a device according to the invention in the following manner:
- A female element 9 is fixed on the arm 25 of the vehicle articulated on the existing axis 25 and is fixed articulated to the connecting member 28. This manner of doing does not require any modification of the vehicle. This female element is permanently fixed to the machine.
- A male element 1 is permanently fixed to the bucket 26 by bolts in the existing fixing holes 17 and 18.
- A male element 1 is permanently fixed to all the tools constituting the series of tools intended to be used with the machine.

De cette manière la fixation de l'outil sur l'engin est simplifiée et permet un changement rapide de l'outil.In this way the attachment of the tool on the machine is simplified and allows a quick change of the tool.

Considérons maintenant avec plus de détails comment est constitué le dispositif.Let us now consider in more detail how the device is made up.

Sur la figure 1, nous voyons un élément mâle M. Cet élément comprend une plaque de base en acier 1 sur la face supérieure de laquelle sont sou­dés des profilés triangulaires en acier de manière à constituer un V. Sur la figure 1, le V est en position horizontale et la pointe du V est tournée vers la gauche. La section du profilé constituant le V est un triangle rectangle isocèle qui est soudé par un des sommets 4 de sa base 22 sur la plaque 1. Comme on le voit sur la figure 3, le triangle constituant le profilé est disposé avec un petit côté 3,constituant un côté de l'angle droit et l'intérieur du V, perpendiculaire à la plaque 1 et l'autre petit côté 2, constituant l'autre côté de l'angle droit et la face supérieure du V, parallèle à la plaque 1 éloigné de celle-ci. Le V apparaît donc sur la plaque de base 1 comme l'avant d'un bateau ayant les côtés extérieures inclinés à 45°. Sur la face inférieure de la plaque sont soudées, symétriquement par rapport à l'axe de symétrie de l'élément mâle M, deux plaques 7 comportant des trous circulaires 17 et 18 (voir figure 4) de manière à permettre la fixation de l'élé­ment M sur un outil. Enfin, la plaque de base 1 possède un trou cir­culaire 5 situé devant la pointe V. Ce trou 5 comporte un renforcement 6 et est destiné à recevoir une broche de fixation figurée par son axe 21.In FIG. 1, we see a male element M. This element comprises a steel base plate 1 on the upper face of which are welded triangular steel sections so as to constitute a V. In FIG. 1, the V is in a horizontal position and the tip of the V is turned to the left. The section of the profile constituting the V is an isosceles right triangle which is welded by one of the vertices 4 of its base 22 on the plate 1. As can be seen in FIG. 3, the triangle constituting the profile is arranged with a small side 3 , constituting one side of the right angle and the interior of the V, perpendicular to the plate 1 and the other short side 2, constituting the other side of the right angle and the upper face of the V, parallel to the plate 1 remote from the latter. The V therefore appears on the base plate 1 like the front of a boat having the outer sides inclined at 45 °. On the underside of the plate are welded, symmetrically with respect to the axis of symmetry of the male element M, two plates 7 having circular holes 17 and 18 (see FIG. 4) so as to allow the fixing of the element M on a tool. Finally, the base plate 1 has a circular hole 5 located in front of the point V. This hole 5 has a reinforcement 6 and is intended to receive a fixing pin shown by its axis 21.

Sur la figure 2, nous voyons un élément femelle F. Cet élément comprend une plaque de base en acier 9 semblable à la plaque de base 1 de l'élément mâle M. Sur la face supérieure de cette plaque 9 sont soudés des profilés triangulaires en acier de manière à constituer un V. Sur la figure 2 le V est en position horizontale et la pointe de V est tournée vers la gauche. La section du profilé constituant le V est un triangle rectangle isocèle qui est soudé par un des sommets 11 de sa base 23 sur la plaque 9. Comme on le voit sur la figure 3 le triangle constituant le profilé est disposé avec un petit côté 10, constituant un côté de l'angle droit et l'extérieur du V, perpendiculaire à la plaque 9 et l'autre petit côté 12, constituant l'autre côté de l'angle droit et la face supérieure du V, parallèle à la plaque 9 éloigné de celle-ci. Le V apparaît donc sur la plaque comme un triangle de chasse-­neige ayant des côtés droits avec à l'intérieur du V un espace ayant des faces inclinées à 45°. Comme pour l'élément M, l'élément F comporte sur sa face inférieure soudées symétriquement par rapport à l'axe de symétrie de l'élément F, deux plaques 15 comportant des trous circulai­res 19 et 20 de manière à permettre la fixation de l'élément F sur un engin (voir figure 5). Enfin, la plaque de base 9 comporte aussi un trou circulaire 13 situé à la pointe du V. Ce trou 13 comporte un ren­forcement 14 et est destiné à venir s'aligner en face du trou 5 de l'élément mâle M, lorsque les deux éléments sont assemblés, de manière à permettre le passage d'un axe ou d'une broche.In FIG. 2, we see a female element F. This element comprises a steel base plate 9 similar to the base plate 1 of the male element M. On the upper face of this plate 9 are triangular sections welded in steel so as to constitute a V. In FIG. 2 the V is in a horizontal position and the point of V is turned to the left. The section of the profile constituting the V is an isosceles right triangle which is welded by one of the vertices 11 of its base 23 on the plate 9. As can be seen in FIG. 3, the triangle constituting the profile is arranged with a small side 10, constituting one side of the right angle and the outside of the V, perpendicular to the plate 9 and the other short side 12, constituting the other side of the right angle and the upper face of the V, parallel to the plate 9 distant from it. The V therefore appears on the plate as a snow plow triangle with straight sides with a space inside the V having faces inclined at 45 °. As for element M, element F comprises on its underside welded symmetrically with respect to the axis of symmetry of element F, two plates 15 having circular holes 19 and 20 so as to allow the fixing of the element F on a machine (see Figure 5). Finally, the base plate 9 also has a circular hole 13 located at the tip of the V. This hole 13 has a reinforcement 14 and is intended to come into alignment opposite the hole 5 of the male element M, when the two elements are assembled, so as to allow the passage of an axis or a spindle.

Le fonctionnement du dispositif pour tout changement d'outil sur un engin équipé d'un tel dispositif se présente de la manière suivante :
- On retire la broche 21 des trous 5 et 13, respectivement de l'élément mâle M et de l'élément femelle F.
- L'outil est déboîté en faisant sortir le V de l'élément mâle du V de l'élément femelle.
- Un autre V d'un élément mâle fixé sur un autre outil est introduit dans le V de l'élément femelle fixé sur l'engin.
- La broche 21 est introduite en place dans les trous 5 et 13 des deux éléments et est maintenue en place par une sécurité.
The operation of the device for any tool change on a machine equipped with such a device is as follows:
- The pin 21 is removed from the holes 5 and 13, respectively of the male element M and the female element F.
- The tool is disengaged by removing the V from the male element from the V from the female element.
- Another V of a male element fixed on another tool is introduced into the V of the female element fixed on the machine.
- The pin 21 is inserted in place in the holes 5 and 13 of the two elements and is held in place by a security.

Comme on le comprend, la manoeuvre est simple et peut être réalisée en très peu de temps.As can be understood, the maneuver is simple and can be carried out in a very short time.

Ce dispositif est très simple à fabriquer et peut être réalisé pour beaucoup de types de machines. Il suffira de faire une pièce femelle pour chaque type de machine et autant de pièces mâles que la machine comporte d'outils.This device is very simple to manufacture and can be produced for many types of machines. It will suffice to make a female part for each type of machine and as many male parts as the machine has tools.

De par sa conception, ce dispositif évite tout mouvement de l'outil sur l'engin. En effet, les deux éléments M et F une fois assemblés ne présentent pas de jeu, car les deux faces à 45° s'appuyent l'une contre l'autre. Le choix de l'angle de 45° a été fait afin de per­mettre une bonne transmission des efforts.By design, this device prevents movement of the tool on the machine. Indeed, the two elements M and F once assembled have no play, because the two faces at 45 ° bear against each other. The 45 ° angle was chosen to allow good transmission of forces.
