Description

ENGIN DE TERRASSEMENT A DISPOSITIF D'ATTACHE RAPIDE ET ADAPTATEUR REVERSIBLE POUR GODET  GROUNDING MACHINE WITH RAPID ATTACHMENT DEVICE AND REVERSIBLE ADAPTER FOR BUCKET
DOMAINE DE L'INVENTION FIELD OF THE INVENTION
L'invention concerne un engin de terrassement à dispositif d'attache rapide et adaptateur réversible pour godet. Un tel engin de terrassement est apte à travailler en mode rétro et en mode chouleur. L'adaptateur réversible est fixé au godet, et présente deux axes de brochage, parallèles entre eux, aptes à être saisis par le dispositif d'attache rapide dans les deux orientations opposées du godet, pour travailler aussi bien en mode rétro avec l'ouverture du godet vers l'engin, qu'en mode chouleur avec l'ouverture du godet à l'opposé de l'engin.  The invention relates to an earthmoving machine with quick coupling device and reversible adapter for bucket. Such an earthmoving machine is able to work in retro mode and in chop mode. The reversible adapter is attached to the bucket, and has two pin axes, parallel to each other, capable of being grasped by the quick coupling device in the two opposite directions of the bucket, to work both in retro mode with the opening from the bucket to the machine, than in the hoist mode with the opening of the bucket opposite the machine.
ART ANTERIEUR  PRIOR ART
Un engin de terrassement de ce type est décrit dans le document EP A earthmoving machine of this type is described in the document EP
I 749 939. Cet engin comporte un adaptateur essentiellement constitué par deux plaques latérales parallèles, reliées par deux axes de brochage. Une fois mis en place sur le godet, l'adaptateur reçoit sur l'un de ses axes les crochets de l'attache rapide et sur l'autre axe d'une part, l'appui de l'extrémité de l'attache rapide opposée aux crochets, et d'autre part, un verrou de fixation. I 749 939. This machine comprises an adapter consisting essentially of two parallel side plates, connected by two pinning pins. Once placed on the bucket, the adapter receives on one of its axes the hooks of the quick coupler and on the other axis on the one hand, the support of the end of the quick coupler opposite the hooks, and secondly, a fastening lock.
Cette obligation d'avoir deux pièces en appui stable sur un axe impose que cet axe présente deux faces planes faisant entre elles un angle déterminé. L'adaptateur étant réversible, ses deux axes doivent présenter les mêmes faces planes, les deux axes étant rigoureusement symétriques. This obligation to have two parts in stable support on an axis requires that this axis has two planar faces forming between them a given angle. The adapter being reversible, its two axes must have the same plane faces, the two axes being rigorously symmetrical.
II en résulte une difficulté de réalisation et une difficulté de montage. This results in a difficulty of realization and difficulty of assembly.
De plus, l'un des deux axes cumule en mode rétro deux fonctions distinctes, reprise des efforts de cavage et verrouillage. Par conséquent, si un défaut apparaît (positionnement, déformation, usure...) sur l'axe en question, il peut en résulter simultanément une conséquence néfaste sur les deux fonctions.  In addition, one of the two axes accumulates in retro mode two distinct functions, recovery efforts digging and locking. Therefore, if a fault appears (positioning, deformation, wear ...) on the axis in question, it can simultaneously result in a detrimental effect on both functions.

DESCRIPTION DETAILLEE  DETAILED DESCRIPTION
Un engin 1 de terrassement avec un bras de manœuvre 2 et un godet 3 est équipé en mode rétro lorsque l'ouverture du godet 3 est tournée vers l'engin 1 (figure 1), et en mode chouleur lorsque l'ouverture du godet 3 est orientée à l'opposé de l'engin 1 (figure 2).  An earth-moving machine 1 with a maneuvering arm 2 and a bucket 3 is equipped in retro mode when the opening of the bucket 3 is turned towards the machine 1 (FIG. 1), and in the hoist mode when the opening of the bucket 3 is facing away from the machine 1 (Figure 2).
Le godet 3 (figure 3) est équipé d'un adaptateur 4 réversible qui permet au dispositif 5 d'attache rapide (figure 4) fixé au bout du bras 2 de manœuvre, de saisir le godet 3 dans chacune des deux positions correspondant aux modes rétro et chouleur.  The bucket 3 (FIG. 3) is equipped with a reversible adapter 4 which enables the quick-attach device 5 (FIG. 4) attached to the end of the operating arm 2 to grip the bucket 3 in each of the two positions corresponding to the modes. retro and chouleur.
L'adaptateur 4 réversible est essentiellement constitué de manière classique de deux plaques latérales 6, 7 et de deux axes 8, 9 de brochage.  The reversible adapter 4 is essentially constituted in a conventional manner by two lateral plates 6, 7 and two pins 8, 9 for broaching.
Les plaques latérales 6, 7 sont symétriques l'une de l'autre par rapport au plan vertical de référence de l'engin 1. Ce plan de référence est un plan vertical passant par l'axe longitudinal du bras 2 de manœuvre. Les plaques latérales 6, 7 sont reliées entre elles par les deux axes 8, 9 de brochage, qui sont perpendiculaires au plan de référence et au plan des plaques latérales 6, 7.  The side plates 6, 7 are symmetrical to one another relative to the vertical reference plane of the machine 1. This reference plane is a vertical plane passing through the longitudinal axis of the operating arm 2. The lateral plates 6, 7 are interconnected by the two broaching pins 8, 9 which are perpendicular to the reference plane and to the plane of the lateral plates 6, 7.
Les axes géométriques des axes de brochage 8, 9 définissent un plan 10. Les deux axes de brochage 8, 9 sont symétriques l'un de l'autre par rapport au plan médian 11 perpendiculaire au plan 10 reliant leurs axes géométriques. La structure de l'adaptateur réversible 4 comprend de façon classique des renforts 12 et des moyens de fixation au godet 3.  The geometric axes of the broaching axes 8, 9 define a plane 10. The two broaching axes 8, 9 are symmetrical to one another relative to the median plane 11 perpendicular to the plane 10 connecting their geometric axes. The structure of the reversible adapter 4 conventionally comprises reinforcements 12 and means for fixing the bucket 3.
Selon l'invention, chaque plaque latérale 6, 7, porte, vers l'intérieur de l'adaptateur 4, une paire de rampes inclinées, ou butées, respectivement 13, 14 et 15, 16. Les rampes d'une même paire, 13, 14 d'une part et 15, 16 d'autre part, sont symétriques l'une de l'autre par rapport au plan médian 11. Les paires de rampes 13, 14 et 15, 16, sont symétriques l'une de l'autre par rapport au plan de référence de l'engin 1. According to the invention, each side plate 6, 7 carries, towards the inside of the adapter 4, a pair of inclined ramps, or stops, respectively 13, 14 and 15, 16. The ramps of the same pair, 13, 14 on the one hand and 15, 16 on the other hand, are symmetrical to one another by relative to the median plane 11. The pairs of ramps 13, 14 and 15, 16, are symmetrical to one another with respect to the reference plane of the machine 1.
Par rapport au plan 10 des axes géométriques des axes 8, 9 de brochage, les rampes 13 à 16 ont une inclinaison comprise entre 5 et 45°, plus précisément entre 10 et 30°, et de préférence de 20°. Dans les exemples de réalisation des figures 5 à 9, les rampes 13 à 16 définissent un dièdre, ouvert vers les axes de brochage et présentant un angle d'ouverture de 140°. L'adaptateur 4 réversible peut être obtenu par assemblage mécano-soudé ou par moulage. Les rampes 13 à 16 sont mécaniquement liées aux plaques latérales.  With respect to the plane 10 of the geometric axes of the axes 8, 9 broaching, the ramps 13 to 16 have an inclination of between 5 and 45 °, more precisely between 10 and 30 °, and preferably 20 °. In the exemplary embodiments of FIGS. 5 to 9, the ramps 13 to 16 define a dihedron, open towards the broaching axes and having an opening angle of 140 °. The reversible adapter 4 can be obtained by mechanically welded assembly or by molding. The ramps 13 to 16 are mechanically connected to the side plates.
Le dispositif 5 d'attache rapide est porté par l'extrémité du bras 2 de l'engin 1. De façon classique, il comporte des crochets 17 dits avant et un verrou 18 dit arrière. Les crochets 17 avant sont disposés symétriquement par rapport au plan de référence de l'engin, à l'état couplé du dispositif 5 d'attache rapide au bras 2 de manœuvre, et sont destinés à recevoir l'un des axes de brochage 8, 9 de l'adaptateur 4 réversible. Le verrou arrière 18 est destiné à s'insérer sous l'autre axe de brochage pour assurer le verrouillage du dispositif d'attache rapide 5 sur l'adaptateur réversible 4. Selon l'invention, le dispositif d'attache rapide 5 comporte deux rampes inclinées 19, 20, destinées à coopérer avec les rampes inclinées de l'adaptateur 4 par appui réciproque.  The quick-release device 5 is carried by the end of the arm 2 of the machine 1. In a conventional manner, it comprises hooks 17 called before and a lock 18 said rear. The front hooks 17 are arranged symmetrically with respect to the reference plane of the machine, in the coupled state of the quick coupling device 5 to the operating arm 2, and are intended to receive one of the pinning axes 8, 9 of the adapter 4 reversible. The rear latch 18 is intended to be inserted under the other pinning axis to lock the quick coupler 5 on the reversible adapter 4. According to the invention, the quick coupler 5 comprises two ramps inclined 19, 20, intended to cooperate with the inclined ramps of the adapter 4 by mutual support.
Dans l'exemple de réalisation des figures 7 et 8, l'engin 1 travaille en mode rétro. Le godet 3 et l'adaptateur réversible 4 sont dans la situation de la figure 3. Le dispositif d'attache rapide 5 a ses crochets 17 en prise sur l'axe de brochage 8 de l'adaptateur réversible 4, et son verrou 18 en position de verrouillage sous l'axe de brochage 9.  In the embodiment of Figures 7 and 8, the machine 1 works in retro mode. The bucket 3 and the reversible adapter 4 are in the situation of FIG. 3. The quick coupling device 5 has its hooks 17 engaged on the pinning axis 8 of the reversible adapter 4, and its latch 18 lock position under the broaching axis 9.
Dans cette position relative du dispositif d'attache rapide 5 et de l'adaptateur réversible 4, la rampe inclinée 20 du dispositif d'attache rapide 5 est en appui sur la rampe inclinée 14 de l'adaptateur réversible 4. De même, la rampe inclinée 19 du dispositif d'attache rapide 5 est en appui sur la rampe inclinée 16 de l'adaptateur réversible 4.  In this relative position of the quick coupler 5 and the reversible adapter 4, the inclined ramp 20 of the quick coupler 5 bears against the inclined ramp 14 of the reversible adapter 4. Likewise, the ramp inclined 19 of the quick coupling device 5 bears on the inclined ramp 16 of the reversible adapter 4.
Dans l'exemple de réalisation de la figure 9, l'engin 1 travaille en mode chouleur. Les crochets 17 du dispositif d'attache rapide sont en prise sur l'axe de brochage 9 de l'adaptateur réversible 4 et le verrou 18 est en position de verrouillage sous l'axe de brochage 8. Les rampes inclinées 19, 20 du dispositif d'attache rapide 5 sont en appui respectivement sur les rampes 13 et 15 de l'adaptateur réversible 4. In the embodiment of Figure 9, the machine 1 works in the chopper mode. The hooks 17 of the quick coupler are engaged on the pinning axis 9 of the reversible adapter 4 and the latch 18 is in position. locking position under the broaching axis 8. The inclined ramps 19, 20 of the quick coupling device 5 bear respectively on the ramps 13 and 15 of the reversible adapter 4.
L'appui réciproque des rampes inclinées 19, 20 du dispositif d'attache rapide 5 sur les rampes inclinées 16, 14, ou 13, 15 respectivement, de l'adaptateur réversible 4 assure une transmission des efforts mécaniques sur les rampes inclinées et non pas sur l'axe de brochage comme dans les adaptateurs de l'art antérieur. Il en résulte un meilleur écoulement des contraintes mécaniques dans la structure du godet, entraînant une meilleure tenue de l'équipement de terrassement aux chargements cycliques. Il en résulte également de moindres efforts de flexion sur l'axe de brochage sous l'action du verrou, d'où une plus grande sécurité de l'équipement de terrassement.  The mutual support of the inclined ramps 19, 20 of the quick coupler 5 on the inclined ramps 16, 14, or 13, respectively, of the reversible adapter 4 ensures a transmission of mechanical forces on the inclined ramps and not on the pinning axis as in the adapters of the prior art. This results in a better flow of mechanical stresses in the bucket structure, resulting in a better holding of the earthmoving equipment to cyclic loadings. This also results in lower bending forces on the pinning axis under the action of the lock, resulting in greater safety of the earthmoving equipment.
Dans le fonctionnement en mode chouleur, lorsque le godet 3 est chargé, l'adaptateur réversible 4 est pratiquement en position verticale, et l'ouverture des crochets 17 du dispositif d'attache rapide 5 est orientée vers le bas. La coopération des rampes inclinées 13 et 19 d'une part, 15 et 20 d'autre part, permet de transférer une partie du poids du godet 3 d'une part sur le verrou 18, d'autre part sur les crochets 17. Il en résulte une réduction des contraintes au niveau du verrou et une amélioration de la sécurité.  In operation in the hoist mode, when the bucket 3 is loaded, the reversible adapter 4 is substantially in a vertical position, and the opening of the hooks 17 of the quick coupler 5 is oriented downwards. The cooperation of inclined ramps 13 and 19 on the one hand, 15 and 20 on the other hand, makes it possible to transfer part of the weight of the bucket 3 on the one hand to the latch 18, on the other hand to the hooks 17. It this results in a reduction of the lock constraints and an improvement in safety.
Par ailleurs, en cas d'usure dans le fond des crochets 17 du dispositif d'attache rapide 5, il y a un jeu entre l'axe de brochage et les crochets 17. Lors d'une baisse de la force de verrouillage appliquée au verrou 18, ou lorsque le verrou 18 est complètement sorti, un tel jeu peut être constaté. Selon l'invention, l'inclinaison des rampes en appui réciproque entraîne une force de réaction dont une composante, parallèle au plan 10 des axes géométriques des axes de brochage 8 et 9, a tendance à ramener l'axe de brochage de l'adaptateur réversible au fond de crochets 17.  Moreover, in case of wear in the bottom of the hooks 17 of the quick coupler 5, there is a clearance between the broaching axis and the hooks 17. During a decrease in the locking force applied to the 18 lock, or when the latch 18 is completely out, such a game can be found. According to the invention, the inclination of the ramps in mutual support results in a reaction force including a component, parallel to the plane 10 of the geometric axes of the pinning axes 8 and 9, tends to reduce the pin axis of the adapter reversible at the bottom of hooks 17.
Selon un mode de réalisation de l'invention, les axes de brochage 8, According to one embodiment of the invention, the pinning axes 8,
9, présentent dans leur zone centrale, une surface plane 21, 22, respectivement. Les surfaces planes 21 et 22 sont disposées symétriquement l'une de l'autre par rapport au plan médian 11. Elles sont inclinées dans le sens d'un rapprochement vers le bas. Elles jouent le rôle de surface de guidage du moyen de verrouillage du dispositif d'attache rapide 5 sur l'adaptateur réversible 4. Au cours de la mise en place du dispositif d'attache rapide 5 sur l'adaptateur réversible 4, la première phase consiste à rapprocher les crochets 17 d'un axe de brochage. Lorsque l'axe de brochage, 8 par exemple, est au fond des crochets 17, le dispositif d'attache rapide 5 est basculé en pivotant sur l'axe de brochage 8. Dans le cas d'un verrou 18 sollicité par ressort, au cours de ce pivotement du dispositif d'attache rapide 5, l'extrémité du pivot 18 arrive au contact de l'axe de brochage 9. En prenant appui sur la surface 22, le verrou 18 est repoussé dans sa gaine en comprimant son ressort. Lorsque l'extrémité libre du verrou 18 sort de la surface 22, le ressort repousse le verrou 18 qui assure le verrouillage sous l'axe de brochage 9. En variante, le verrou 18 arrière peut être sollicité par un vérin tel qu'un vérin hydraulique. 9, have in their central zone, a flat surface 21, 22, respectively. The planar surfaces 21 and 22 are arranged symmetrically to one another with respect to the median plane 11. They are inclined in the direction of a downward approach. They play the role the guide surface of the locking means of the quick coupling device 5 on the reversible adapter 4. During the installation of the quick coupling device 5 on the reversible adapter 4, the first phase consists in bringing the hooks 17 of a pinning axis. When the broaching pin 8, for example, is at the bottom of the hooks 17, the quick coupling device 5 is pivotally pivoted onto the broaching pin 8. In the case of a latch 18 biased by spring, to the during this pivoting of the quick coupling device 5, the end of the pivot 18 comes into contact with the pin pin 9. By bearing on the surface 22, the latch 18 is pushed into its sheath by compressing its spring. When the free end of the latch 18 leaves the surface 22, the spring pushes the latch 18 which locks under the pin pin 9. Alternatively, the latch 18 back can be solicited by a jack such as a jack hydraulic.
Les avantages de l'invention sont liés à la disposition des rampes inclinées symétriques dans l'adaptateur réversible et dans le dispositif d'attache rapide. Un seul adaptateur réversible avec un profil de contact symétrique assure la reprise des efforts dans les deux modes de fonctionnement, rétro et chouleur. Le profil et l'angle des rampes inclinées sont déterminés pour apporter le meilleur compromis entre reprise d'effort et rattrapage de jeu, et une meilleure transmission des efforts de cavage, évitant la flexion sur l'axe de brochage assurant le verrouillage. Les contraintes mécaniques sont directement reprises par les plaques latérales de l'adaptateur réversible et sont ensuite diluées vers le godet 1 alors que dans l'art antérieur, une reprise centrale des contraintes provoque une flexion-compression de l'axe de brochage assurant le verrouillage, qui est néfaste à la tenue en fatigue. La dissociation entre les pièces assurant, d'une part la reprise des efforts principaux de cavage et d'autre part le verrouillage de l'attache rapide sur l'adaptateur réversible, induit une meilleure gestion de l'usure.  The advantages of the invention are related to the arrangement of symmetrical inclined ramps in the reversible adapter and in the quick coupling device. A single reversible adapter with a symmetrical contact profile ensures the recovery of forces in both operating modes, retro and chouleur. The profile and the angle of the inclined ramps are determined to provide the best compromise between recovery of effort and play catch, and a better transmission of the tilting forces, avoiding bending on the pinning pin ensuring locking. The mechanical stresses are directly taken up by the side plates of the reversible adapter and are then diluted towards the bucket 1 whereas in the prior art, a central recovery of the stresses causes a bending-compression of the pinning axis ensuring the locking which is detrimental to fatigue. The dissociation between the parts ensuring, on the one hand the recovery of the main efforts of digging and on the other hand the locking of the quick coupler on the reversible adapter, induces a better management of the wear.
