Description

La présente invention se rapporte au domaine des travaux publics, et, en particulier, des travaux de terrassement.The present invention relates to the field of public works, and, in particular, earthworks.

La présente invention porte en particulier sur un dispositif de terrassement adaptable sur le tablier d'un chariot télescopique pour permettre le terrassement en profondeur dans le sol par l'intermédiaire d'un godet porté par celui-ci, ainsi que sur un chariot télescopique équipé d'un tel dispositif de terrassement.The present invention relates in particular to an earthmoving device adaptable to the deck of a telescopic trolley to allow earthwork deep into the ground via a bucket carried by it, and on a telescopic trolley equipped of such earth moving device.

Les travaux de terrassement sont généralement effectués à l'aide d'un engin de terrassement classique.Earthworks are generally performed using a conventional earthmoving machine.

Il existe actuellement dans le commerce de nombreux engins de terrassement, tels que les pelles mécaniques, également appelées pelleteuses ou excavatrices, les chargeuses, etc.There are currently many earth-moving machines on the market, such as excavators, also known as diggers or excavators, loaders, and so on.

Les godets pour travaux publics qui permettent le creusement et le déplacement de la terre, sont généralement installés à l'arrière ou à l'avant, et dans l'axe de tels engins de terrassement.The buckets for public works which allow the digging and the displacement of the earth, are generally installed at the back or in the front, and in the axis of such earth-moving machines.

Ces engins de terrassement classiques comprennent un châssis porteur à chenilles ou à pneus, surmonté d'une tourelle dotée d'une rotation continue sur 360 degrés, laquelle tourelle porte le moteur, les organes hydrauliques, le poste de conduite et l'équipement par le biais d'une liaison pivot, à savoir un bras, une flèche, un balancier et un godet.These conventional earth-moving machines comprise a tracked or pneumatic undercarriage, surmounted by a turret endowed with a 360-degree continuous rotation, which turret carries the engine, the hydraulic components, the driving position and the equipment by the through a pivot connection, namely an arm, an arrow, a balance and a bucket.

Par ailleurs, l'outil porté par ces engins de terrassement, notamment le godet, est généralement monté de manière démontable. Ainsi, un engin unique peut être équipé d'un autre outil interchangeable afin d'effectuer des travaux différents.Moreover, the tool carried by these earthmoving machines, in particular the bucket, is generally dismountably mounted. Thus, a single gear can be equipped another interchangeable tool to perform different jobs.

Il est également connu d'adapter des outils de terrassement sur des véhicules existants, notamment sur un chariot télescopique.It is also known to adapt earthmoving tools on existing vehicles, especially on a telescopic wagon.

Les chariots télescopiques comportent un mât télescopique, qui fait monter et descendre, généralement au moyen d'un vérin hydraulique, l'outil portant la charge, tel qu'une fourche, lequel outil étant porté par un tablier prévu à l'extrémité du mât. A sa partie inférieure, le mât est articulé autour d'un axe horizontal de façon à pouvoir être incliné par rapport à la verticale, au moyen d'un système à vérins.The telescopic carriages comprise a telescopic mast, which raises and lowers, generally by means of a hydraulic jack, the tool carrying the load, such as a fork, which tool is carried by an apron provided at the end of the mast. . At its lower part, the mast is articulated around a horizontal axis so as to be inclined relative to the vertical, by means of a jack system.

Il existe déjà, pour ces chariots télescopiques, divers types d'outils adaptables, tels qu'une potence, une benne, une fourche presseuse, etc. Cependant, ces outils sont généralement prévus pour être montés directement sur le tablier, à la place de la fourche classique, de sorte qu'ils ne peuvent être déplacés que par l'inclinaison du mât. Ceci limite leurs possibilités de travail, telles que la profondeur de la tranchée que l'on peut obtenir, ainsi que rend délicate la manoeuvre du godet.There are already, for these telescopic carriages, various types of adaptable tools, such as a stem, a bucket, a pressing fork, etc. However, these tools are generally intended to be mounted directly on the deck, instead of the conventional fork, so that they can be moved only by the inclination of the mast. This limits their working possibilities, such as the depth of the trench that can be obtained, as well as makes it difficult to maneuver the bucket.

Le brevet français FR2058743 décrit un dispositif pour le pelletage en rétro adaptable sur la tête de flèche d'une machine automotrice de manutention. Ce dispositif comprend un support solidarisé à la tête de flèche et un godet monté pivotant par rapport au support selon un axe horizontal par l'intermédiaire d'un vérin et d'un renvoi d'angle.French patent FR2058743 describes a device for shoveling retro-adaptable on the boom head of a self-propelled machine handling. This device comprises a support secured to the boom head and a bucket pivotally mounted relative to the support along a horizontal axis by means of a jack and a bevel gear.

Cependant, ce dispositif ne permet pas le déplacement en hauteur du godet, lequel déplacement en hauteur est nécessaire pour le creusement d'une tranchée. En effet, un tel mouvement est obtenu uniquement par déplacement du mât mobile et de la flèche télescopique de la machine de manutention.However, this device does not allow the displacement of the bucket height, which height displacement is necessary for the digging of a trench. Indeed, such a movement is obtained only by displacement of the mobile mast and the telescopic boom of the handling machine.

On peut également citer le brevet français FR1308396 et le brevet américain US4822237 qui décrivent des engins de manutention comportant une flèche télescopique sur laquelle est articulé un ensemble de bras également articulés entre eux et portant un dispositif de travail, tel qu'un racloir, un godet, une fourche, etc., ou encore les brevets américains US2010/014952 , US4150504 et US2008/025830 qui décrivent un véhicule, tel qu'un chargeur, comportant un support de montage sur lequel est articulée une rétrocaveuse dont les bras articulés entre eux portent un godet. Cependant, en raison du montage pivotant de l'ensemble de bras sur la flèche ou sur le support porté par l'engin, ledit ensemble bras n'est pas adaptable sur le tablier d'un chariot télescopique sans modification de celui-ci. Par ailleurs, leur structure est complexe et n'est pas compacte.We can also mention the French patent FR1308396 and the US patent US4822237 which describe handling equipment comprising a telescopic boom on which is articulated a set of arms also articulated together and carrying a working device, such as a scraper, a bucket, a fork, etc., or even US patents US2010 / 014952 , US4150504 and US2008 / 025830 which describe a vehicle, such as a loader, comprising a mounting bracket on which is articulated a backhoe whose arms articulated between them carry a bucket. However, because of the pivoting mounting of the arm assembly on the boom or on the support carried by the machine, said arm assembly is not adaptable to the deck of a telescopic truck without modification thereof. Moreover, their structure is complex and is not compact.

Il existe donc un besoin pour un dispositif de terrassement adaptable sur un véhicule existant, tel qu'un chariot télescopique, entre le tablier et l'outil lui-même, permettant de faciliter la manoeuvre du godet tout en augmentant les possibilités de travail de creusement du godet.There is therefore a need for an earthmoving device adaptable to an existing vehicle, such as a telescopic carriage, between the deck and the tool itself, to facilitate the operation of the bucket while increasing the digging job opportunities of the bucket.

La présente invention vise à résoudre les inconvénients de l'état antérieur de la technique, en proposant un dispositif de terrassement apte à être monté sur le tablier d'un chariot télescopique et à porter l'outil, lequel dispositif permet de faire pivoter le godet autour d'un axe horizontal, et également de déplacer le godet en hauteur, et de préférence également de manière transversale, permettant ainsi d'effectuer le creusement d'une tranchée et, le cas échéant le vidage du godet à côté de la tranchée, sans avoir à déplacer le chariot ou à déplacer et allonger le mât du chariot.The present invention aims to solve the disadvantages of the prior art, by proposing a terracing device adapted to be mounted on the apron of a telescopic carriage and to carry the tool, which device allows to rotate the bucket around a horizontal axis, and also to move the bucket height, and preferably also transversely, thus making it possible to dig a trench and, where appropriate emptying the bucket next to it trench without having to move the carriage or move and extend the mast of the trolley.

La présente invention a donc pour objet un dispositif de terrassement adaptable sur le tablier d'un chariot télescopique, lequel dispositif est destiné à porter un outil tel qu'un godet, le dispositif comprenant un support de montage, destiné à être rendu solidaire du tablier, portant un moyen de pivotement du godet destiné à être relié à pivotement autour d'un premier axe horizontal à un godet, caractérisé par le fait que le support de montage porte en outre un moyen de déplacement en hauteur du godet, relié entre le support de montage et le moyen de pivotement, le moyen de pivotement étant relié à pivotement autour d'un deuxième axe horizontal au moyen de déplacement, ledit deuxième axe étant parallèle audit premier axe et étant situé entre ce dernier et le support de montage, de telle sorte qu'un pivotement du moyen de pivotement autour du deuxième axe entraîne un déplacement en hauteur du godet.The present invention therefore relates to an earth moving device adaptable to the deck of a telescopic carriage, which device is intended to carry a tool such as a bucket, the device comprising a mounting bracket, intended to be secured to the deck , carrying a pivoting means of the bucket intended to be pivotally connected about a first horizontal axis to a bucket, characterized in that the mounting support further carries a means for moving the bucket height, connected between the support mounting means and the pivoting means, the pivoting means being pivotally connected about a second horizontal axis to the moving means, said second axis being parallel to said first axis and being situated therebetween and the mounting bracket, such so that a pivoting of the pivoting means around the second axis causes a displacement of the bucket height.

Ainsi, le godet n'est pas monté directement sur le tablier et peut être manoeuvré sans avoir à utiliser le mât du chariot. En outre, les opérations de terrassement, telles que le creusement d'une tranchée, peuvent être effectuées sans déplacement du chariot, uniquement par commande du dispositif de terrassement.Thus, the bucket is not mounted directly on the deck and can be operated without having to use the mast of the carriage. In addition, earthmoving operations, such as the digging of a trench, can be performed without moving the carriage, only by control of the earth moving device.

Selon un mode de réalisation particulier, le moyen de pivotement comprend un premier bras monté pivotant autour du deuxième axe horizontal, lequel premier bras est destiné à être relié par l'une de ses extrémités au godet et porte un premier vérin de commande de l'inclinaison du godet à son autre extrémité, le premier vérin ayant un corps monté à rotation autour d'un quatrième axe horizontal à ladite autre extrémité du premier bras et une tige destinée à être reliée au godet à rotation autour d'un cinquième axe horizontal.According to a particular embodiment, the pivoting means comprises a first arm pivotally mounted about the second horizontal axis, which first arm is intended to be connected by one of its ends to the bucket and carries a first control cylinder of the tilting of the bucket at its other end, the first ram having a body rotatably mounted about a fourth horizontal axis at said other end of the first arm and a rod intended to be connected to the rotating bucket around a fifth horizontal axis.

On entend ici par bras tout élément fixe ou mobile supportant un organe ou outil éloigné du bâti du chariot.Here means by arm any fixed or movable element supporting a member or tool remote from the frame of the carriage.

Dans ce mode de réalisation particulier, le moyen de déplacement comprend un second bras relié au support de montage et dont une extrémité est reliée à pivotement au premier bras autour du deuxième axe horizontal, et dont l'autre extrémité porte un second vérin de commande de l'inclinaison du premier bras, le second vérin ayant un corps monté à rotation autour d'un sixième axe horizontal à l'extrémité du second bras et une tige montée à rotation autour d'un septième axe horizontal au voisinage de l'extrémité du premier bras portant le premier vérin.In this particular embodiment, the displacement means comprises a second arm connected to the mounting bracket and one end of which is pivotally connected to the first arm about the second horizontal axis, and the other end of which carries a second control cylinder. the inclination of the first arm, the second cylinder having a body rotatably mounted about a sixth horizontal axis at the end of the second arm and a rod rotatably mounted about a seventh horizontal axis in the vicinity of the end of the first arm carrying the first cylinder.

Avantageusement, le moyen de déplacement est en outre monté mobile en translation par rapport au support de montage le long d'un troisième axe horizontal parallèle auxdits premier et deuxième axes.Advantageously, the displacement means is further mounted movable in translation relative to the mounting bracket along a third horizontal axis parallel to said first and second axes.

Ainsi, l'opération de vidage du godet peut être effectuée uniquement par commande du dispositif de terrassement, sans avoir à déplacer le chariot ou le mât du chariot.Thus, the emptying operation of the bucket can be performed only by controlling the earth moving device, without having to move the carriage or the mast of the carriage.

De préférence, le support de montage comprend deux montants latéraux pour la fixation au tablier, entre lesquels s'étend au moins un rail de guidage pour le guidage en translation du moyen de déplacement le long du troisième axe horizontal, un troisième vérin fixé d'une part au support de montage et d'autre part au second bras étant prévu pour la commande du déplacement en translation du moyen de déplacement.Preferably, the mounting support comprises two lateral uprights for fastening to the deck, between which at least one guide rail extends for the translational guidance of the displacement means along the third horizontal axis, a third fixed cylinder of a part to the mounting bracket and secondly to the second arm being provided for controlling the translational movement of the displacement means.

Les rails de guidage peuvent être au nombre de deux et être une poutre à section transversale carrée et un arbre de section transversale ronde, le second bras ayant un évidement de forme carrée et un trou correspondant pour le passage des rails de guidage.The guide rails may be two in number and may be a square cross-section beam and a round cross-section shaft, the second arm having a square-shaped recess and a corresponding hole for the passage of the guide rails.

Dans un autre mode de réalisation particulier, les bras comprennent chacun deux ailes parallèles entre elles, écartées l'une de l'autre et en regard l'une de l'autre, les ailes du premier bras étant disposées entre les ailes du second bras et en contact avec celles-ci.In another particular embodiment, the arms each comprise two wings parallel to one another, spaced apart from one another and facing one another, the wings of the first arm being arranged between the wings of the second arm and in contact with them.

Avantageusement, le premier bras, le cas échéant chaque aile, a sensiblement une forme de V, de préférence avec un angle de 112 degrés.Advantageously, the first arm, where appropriate each wing, is substantially V-shaped, preferably with an angle of 112 degrees.

Avantageusement, le second bras, le cas échéant chaque aile, a sensiblement une forme de V, de préférence avec un angle de 128 degrés.Advantageously, the second arm, where appropriate each wing, is substantially V-shaped, preferably with an angle of 128 degrees.

La présente invention a également pour objet un chariot télescopique équipé du dispositif de terrassement tel que défini ci-dessus.The present invention also relates to a telescopic carriage equipped with the earth moving device as defined above.

Pour mieux illustrer l'objet de la présente invention, on va en décrire ci-après, à titre illustratif et non limitatif, un mode de réalisation préféré, avec référence au dessin annexé.To better illustrate the object of the present invention will be described below, by way of illustration and not limited to, a preferred embodiment, with reference to the accompanying drawing.

Le dispositif de terrassement 1 de la présente invention, comme représenté sur la Figure 1, comprend un support de montage 2, destiné à être fixé au tablier 3 d'un chariot télescopique 4, et portant deux bras 5, 6 articulés entre eux, chaque bras 5, 6 portant en outre un vérin 7, 8.The earth moving device 1 of the present invention, as shown in FIG. Figure 1 , comprises a mounting bracket 2, intended to be fixed to the deck 3 of a telescopic carriage 4, and carrying two arms 5, 6 hinged together, each arm 5, 6 further carrying a cylinder 7, 8.

Plus précisément, les deux bras 5, 6 comprennent un premier bras 5, destiné à porter un outil de type godet 9, et un second bras 6, interposé entre le support de montage 2 et le premier bras 5 et relié de manière non articulée au support de montage 2.More specifically, the two arms 5, 6 comprise a first arm 5, intended to carry a bucket type tool 9, and a second arm 6, interposed between the mounting bracket 2 and the first arm 5 and non-articulately connected to the mounting bracket 2.

Le support de montage 2 comprend deux montants 2a, 2b verticaux parallèles entre eux et en regard l'un de l'autre, espacés d'une certaine distance. Ces montants 2a, 2b sont destinés à être reliés au tablier 3 d'un chariot télescopique 4 par l'intermédiaire d'une plaque 2c à laquelle les bords côté tablier des montants 2a, 2b sont fixés. Des moyens de fixation amovible du support de montage 2 au tablier 3, lesquels moyens sont bien connus en soit, pourront être prévus sur le support de montage 2.The mounting bracket 2 comprises two uprights 2a, 2b vertical parallel to each other and facing one another, spaced a certain distance. These uprights 2a, 2b are intended to be connected to the deck 3 of a telescopic truck 4 via a plate 2c to which the deck-side edges of the uprights 2a, 2b are fixed. Removable fixing means of the mounting bracket 2 to the apron 3, which means are well known in either, may be provided on the mounting bracket 2.

Les montants 2a, 2b sont également reliés entre eux par deux rails de guidage 21, 22. Les rails de guidage 21, 22 se présentent de préférence sous la forme d'une poutre creuse de section carrée 22 et d'un arbre rond plein 21. L'arbre plein 21 s'étend entre les deux montants 2a, 2b en faisant légèrement saillie de part et d'autre de ceux-ci, sensiblement à mi-hauteur des montants 2a, 2b. La poutre creuse 22 s'étend entre les deux montants 2a, 2b en faisant légèrement saillie de part et d'autre de ceux-ci, au voisinage de l'extrémité inférieure des montants 2a, 2b.The amounts 2a, 2b are also interconnected by two guide rails 21, 22. The guide rails 21, 22 are preferably in the form of a hollow beam of square section 22 and a solid round shaft 21. The solid shaft 21 extends between the two uprights 2a, 2b protruding slightly from the side and other of these, substantially halfway up the amounts 2a, 2b. The hollow beam 22 extends between the two uprights 2a, 2b projecting slightly on either side thereof, in the vicinity of the lower end of the uprights 2a, 2b.

Le second bras 6 est monté coulissant sur les rails de guidage 21, 22 du support de montage 2. Le mouvement de coulissement du second bras 6 par rapport au support de montage 2 est commandé par un vérin 10 relié entre le support de montage 2 et le second bras 6.The second arm 6 is slidably mounted on the guide rails 21, 22 of the mounting bracket 2. The sliding movement of the second arm 6 relative to the mounting bracket 2 is controlled by a jack 10 connected between the mounting bracket 2 and the second arm 6.

Plus particulièrement, comme on peut le voir sur les Figures 2 et 4, le vérin 10 est relié entre le support de montage 2 et le second bras 6 par l'intermédiaire de deux barres articulées 11, 12. La première barre 11 a une extrémité inférieure reliée à la plaque 2c par une liaison pivot, en partie haute de la plaque 2c et au voisinage de l'une des montants 2b. La seconde barre 12 a une extrémité inférieure reliée au second bras 6 par une liaison pivot. Les première 11 et seconde 12 barres sont articulées entre elles au niveau de leur extrémité supérieure, par une liaison pivot. Les première et seconde barres 11, 12 ont sensiblement la même longueur. La seconde barre 12 comporte en outre une branche 12a qui s'étend sensiblement perpendiculairement à celle-ci à l'opposé de la première barre 11, dans le même plan que les première et seconde barres 11, 12. Le vérin 10 comporte un corps 10a dont l'extrémité est montée pivotante à l'extrémité libre de la branche 12a autour d'un axe de pivotement perpendiculaire au plan des première et seconde barres 11, 12. Le vérin 10 comporte en outre une tige 10b dont l'extrémité libre est articulée à la première barre 11, au voisinage de la région d'extrémité supérieure de la première barre 11.In particular, as can be seen from the Figures 2 and 4 , the jack 10 is connected between the mounting bracket 2 and the second arm 6 by means of two articulated bars 11, 12. The first bar 11 has a lower end connected to the plate 2c by a pivot connection, in the upper part of the plate 2c and in the vicinity of one of the uprights 2b. The second bar 12 has a lower end connected to the second arm 6 by a pivot connection. The first 11 and second 12 bars are hinged together at their upper end by a pivot connection. The first and second bars 11, 12 have substantially the same length. The second bar 12 further comprises a branch 12a which extends substantially perpendicular thereto opposite the first bar 11, in the same plane as the first and second bars 11, 12. The jack 10 comprises a body 10a whose end is pivotally mounted at the free end of the branch 12a about a pivot axis perpendicular to the plane of the first and second bars 11, 12. The jack 10 further comprises a rod 10b whose free end is articulated to the first bar 11, in the vicinity of the upper end region of the first bar 11.

Ainsi, une extension ou une rétractation de la tige 10b du vérin 10 permet d'écarter ou de rapprocher les barres articulées 11, 12 l'une de l'autre et donc de déplacer le second bras 6 entre les deux montants 2a, 2b du support de montage 2.Thus, an extension or a retraction of the rod 10b of the jack 10 makes it possible to move the articulated bars 11, 12 away from one another and thus to move the second arm 6 between the two uprights 2a, 2b of the mounting bracket 2.

Comme on peut le voir sur les Figures 2 et 4, le premier bras 5 comprend deux ailes 5a, 5b, sensiblement en forme de V, montées parallèles entre elles, en regard l'une de l'autre et avec un certain espacement entre celles-ci.As can be seen on the Figures 2 and 4 , the first arm 5 comprises two wings 5a, 5b, substantially V-shaped, mounted parallel to each other, facing one another and with a certain spacing therebetween.

De préférence, chaque aile 5a, 5b du premier bras 5 a une épaisseur de 15 mm, et un angle définit entre les deux branches du V d'environ 112 degrés.Preferably, each wing 5a, 5b of the first arm 5 has a thickness of 15 mm, and an angle defines between the two branches of the V of about 112 degrees.

Le second bras 6 comprend également deux ailes 6a, 6b, sensiblement en forme de V, montées parallèles entre elles, en regard l'une de l'autre et avec un certain espacement entre celles-ci.The second arm 6 also comprises two wings 6a, 6b, substantially V-shaped, mounted parallel to each other, facing one another and with a certain spacing therebetween.

L'espacement entre les ailes 6a, 6b du second bras 6 est supérieur à l'espacement entre les ailes 5a, 5b du premier bras 5.The spacing between the flanges 6a, 6b of the second arm 6 is greater than the spacing between the flanges 5a, 5b of the first arm 5.

De préférence, l'écartement entre les ailes du second bras est de 100 mm, et l'écartement entre les ailes du premier bras est de 70 mm.Preferably, the spacing between the wings of the second arm is 100 mm, and the spacing between the wings of the first arm is 70 mm.

Chaque aile 5a, 5b du premier bras 5 comporte quatre trous traversants 51, 52, 53, 54 disposés de manière correspondante et chaque aile 6a, 6b du second bras 6 comporte trois trous traversants 61, 62, 63 disposés de manière correspondante et un évidement 64 de section carrée.Each wing 5a, 5b of the first arm 5 has four through holes 51, 52, 53, 54 arranged in a corresponding manner and each wing 6a, 6b of the second arm 6 has three through holes 61, 62, 63 arranged correspondingly and a recess. 64 square section.

En particulier, chaque aile 5a, 5b du premier bras 5 comporte un premier trou traversant 51 au voisinage de l'une de ses extrémités dite inférieure, les deux premiers trous traversants 51 du premier bras 5 recevant un arbre d'articulation 55 définissant un premier axe d'articulation A1. Le godet 9 est destiné à être monté à rotation autour de ce premier axe d'articulation A1.In particular, each wing 5a, 5b of the first arm 5 has a first through hole 51 in the vicinity of one of its ends called lower, the first two through holes 51 of the first arm 5 receiving a hinge shaft 55 defining a first hinge pin A1. The bucket 9 is intended to be rotatably mounted around this first hinge axis A1.

Chaque aile 5a, 5b du premier bras 5 comporte également un deuxième trou traversant 52 au niveau de la base du V. Chaque aile 6a, 6b du second bras 6 comporte un premier trou traversant 61 au voisinage de l'une de ses extrémités dite inférieure. Un arbre d'articulation 56 définissant un deuxième axe d'articulation A2 est reçu à travers les premiers trous traversants 61 du second bras 6 et les deuxièmes trous traversants 52 du premier bras 5, de telle sorte que le premier bras 5 est mobile en rotation autour de ce deuxième axe d'articulation A2 à l'extrémité inférieure du second bras 6. Comme on peut le voir sur les Figures, en particulier les Figures 1, 3 et 5A à 5C, la position du deuxième axe A2 relativement au support de montage 2 est fixe. En d'autres termes, ce deuxième axe d'articulation A2 est immobile par rapport au support de montage 2, en particulier sa hauteur.Each wing 5a, 5b of the first arm 5 also comprises a second through hole 52 at the base of the V. Each wing 6a, 6b of the second arm 6 has a first through hole 61 in the vicinity of one of its ends said lower . A hinge shaft 56 defining a second hinge axis A2 is received through the first through holes 61 of the second arm 6 and the second through holes 52 of the first arm 5, so that the first arm 5 is rotatable. around this second axis of articulation A2 at the lower end of the second arm 6. As can be seen in the figures, in particular the Figures 1, 3 and 5A to 5C , the position of the second axis A2 relative to the mounting bracket 2 is fixed. In other words, this second axis of articulation A2 is stationary relative to the mounting bracket 2, in particular its height.

Chaque aile 6a, 6b du second bras 6 comporte, au niveau de la base du V, un évidement 64 de section carrée et un deuxième trou traversant 62 juste au-dessus. Cet évidement 64 est apte à recevoir un rail de guidage 22 de section carrée correspondante du support de montage 2 et le deuxième trou traversant 62 est apte à recevoir un arbre plein 21 de même diamètre, de telle sorte que le second bras 6 est apte à coulisser le long des rails de guidage 21, 22 selon un troisième axe horizontal A3.Each wing 6a, 6b of the second arm 6 comprises, at the base of the V, a recess 64 of square section and a second through hole 62 just above. This recess 64 is adapted to receive a guide rail 22 of corresponding square section of the mounting bracket 2 and the second through hole 62 is adapted to receive a solid shaft 21 of the same diameter, so that the second arm 6 is adapted to slide along the guide rails 21, 22 along a third horizontal axis A3.

Chaque aile 5a, 5b du premier bras 5 comporte un troisième trou traversant 53 au niveau de son autre extrémité, dite supérieure, les deux troisièmes trous traversants 53 du premier bras 5 recevant un arbre d'articulation 57 définissant un quatrième axe d'articulation A4.Each wing 5a, 5b of the first arm 5 has a third through hole 53 at its other end, said upper, the two third through holes 53 of the first arm 5 receiving a hinge shaft 57 defining a fourth axis of articulation A4 .

Ce quatrième axe d'articulation A4 porte l'extrémité du corps 7a d'un premier vérin 7. Ainsi, le premier vérin 7 est mobile en rotation autour du quatrième axe d'articulation A4 à l'extrémité supérieure du premier bras 5.This fourth articulation axis A4 carries the end of the body 7a of a first cylinder 7. Thus, the first cylinder 7 is rotatable about the fourth axis of articulation A4 at the upper end of the first arm 5.

De préférence, le premier vérin 7 a un corps 7a ayant un diamètre de 70 mm.Preferably, the first jack 7 has a body 7a having a diameter of 70 mm.

La tige 7b du premier vérin 7 comporte un trou traversant 71 destiné à recevoir un cinquième axe d'articulation A5 lui-même destiné à être relié au godet 9.The rod 7b of the first jack 7 has a through hole 71 intended to receive a fifth axis of articulation A5 itself intended to be connected to the bucket 9.

Ainsi, le godet 9 est destiné à être monté en rotation à la fois à l'extrémité inférieure du premier bras 5 et à l'extrémité de la tige 7b du premier vérin 7.Thus, the bucket 9 is intended to be mounted in rotation both at the lower end of the first arm 5 and at the end of the rod 7b of the first cylinder 7.

Le premier bras 5 et le premier vérin 7 constituant alors un moyen de pivotement du godet 9.The first arm 5 and the first cylinder 7 then constituting a pivoting means of the bucket 9.

Chaque aile 6a, 6b du second bras 6 comporte un troisième trou traversant 63 au niveau de l'extrémité supérieure du second bras 6, lesquels trous traversants 63 reçoivent un sixième axe d'articulation A6.Each wing 6a, 6b of the second arm 6 has a third through hole 63 at the upper end of the second arm 6, which through holes 63 receive a sixth axis of articulation A6.

L'extrémité du corps 8a d'un second vérin 8 est montée à rotation autour de ce sixième axe d'articulation A6, l'extrémité de la tige 8b de ce second vérin 8 ayant également un trou traversant 81 recevant un septième axe d'articulation A7.The end of the body 8a of a second cylinder 8 is rotatably mounted around this sixth axis of articulation A6, the end of the rod 8b of this second cylinder 8 also having a through hole 81 receiving a seventh axis of articulation A7.

De préférence, le second vérin 8 a un corps 8a ayant un diamètre de 70 mm.Preferably, the second cylinder 8 has a body 8a having a diameter of 70 mm.

Chaque aile 5a, 5b du premier bras 5 comporte, à proximité de sa région d'extrémité supérieure, un quatrième trou traversant 54. Les quatrièmes trous traversants 54 du premier bras 5 reçoivent le septième axe d'articulation A7 de la tige 8b du second vérin 8.Each wing 5a, 5b of the first arm 5 comprises, near its upper end region, a fourth through hole 54. The fourth through holes 54 of the first arm 5 receive the seventh axis of articulation A7 of the rod 8b of the second cylinder 8.

Ainsi, le second vérin 8 est monté mobile entre l'extrémité supérieure du second bras 6 et le voisinage de la région d'extrémité supérieure du premier bras 5, pour commander le mouvement de pivotement du premier bras 5 par rapport au second bras 6.Thus, the second jack 8 is mounted movably between the upper end of the second arm 6 and the vicinity of the upper end region of the first arm 5, to control the pivoting movement of the first arm 5 relative to the second arm 6.

Le second bras 6 et le second vérin 8 constituant alors un moyen de déplacement latéral et en hauteur du godet 9. Le déplacement en hauteur et vers et à l'opposé du chariot 4 portant le dispositif 1 étant effectué par pivotement du premier bras 5 par l'intermédiaire du second vérin 8 et le déplacement latéral dans une direction transversale au chariot 4 étant effectué par translation du second bras 6 le long des rails de guidage 21, 22.The second arm 6 and the second cylinder 8 then constituting means for lateral displacement and height of the bucket 9. The displacement in height and towards and away from the carriage 4 carrying the device 1 being effected by pivoting the first arm 5 by via the second cylinder 8 and the lateral displacement in a direction transverse to the carriage 4 being effected by translation of the second arm 6 along the guide rails 21, 22.

Comme on peut le voir sur la Figure 6, le dispositif de terrassement 1 selon la présente invention est adaptable sur le tablier 3 d'un chariot télescopique 4. En particulier, le support de montage 2 est fixé au tablier 3 avec ses deux montants 2a, 2b disposés verticalement et ses rails de guidage 21, 22 disposés horizontalement. Un godet 9 est ensuite fixé à l'extrémité inférieure de chaque aile 5a, 5b du premier bras 5.As can be seen on the Figure 6 , the earth moving device 1 according to the present invention is adaptable to the deck 3 of a telescopic truck 4. In particular, the mounting bracket 2 is fixed to the deck 3 with its two uprights 2a, 2b arranged vertically and its guide rails 21, 22 arranged horizontally. A bucket 9 is then attached to the lower end of each wing 5a, 5b of the first arm 5.

Comme on peut le voir sur les Figures 5A, 5B et 5C, le dispositif de terrassement 1 ainsi fixé peut être utilisé pour le creusement en profondeur d'un trou et/ou d'une tranchée.As can be seen on the Figures 5A , 5B and 5C the earth moving device 1 thus fixed can be used for deep digging of a hole and / or a trench.

Pour cela, le godet 9 est tout d'abord positionné au-dessus du sol, à l'endroit où la tranchée doit être creusée, avec son ouverture dirigée vers le bas, comme représenté sur la Figure 5A.For this, the bucket 9 is first positioned above the ground, where the trench must be dug, with its downward opening, as shown on the Figure 5A .

Ensuite, le godet 9 est amené à pivoter de manière à entrer dans le sol, comme représenté sur la Figure 5B. Pour cela, le premier bras 5 est amené à pivoter à l'opposé du chariot 4, autour du deuxième axe A2 de pivotement horizontal, par pivotement du second vérin 8 à l'opposé du chariot 4 autour du sixième axe A6 de pivotement horizontal et extension de la tige 8b du second vérin 8. Le premier bras 5 est ainsi amené à pivoter autour du deuxième axe A2, dont la hauteur ne change pas, ce qui fait descendre le godet 9 sans que le mât du chariot 4 n'ait à être déplacé.Then, the bucket 9 is pivoted to enter the ground, as shown in FIG. Figure 5B . For this, the first arm 5 is pivoted away from the carriage 4, around the second axis A2 of horizontal pivoting, by pivoting the second cylinder 8 opposite the carriage 4 about the sixth axis A6 horizontal pivoting and extension of the rod 8b of the second cylinder 8. The first arm 5 is thus caused to pivot about the second axis A2, the height of which does not change, which causes the bucket 9 to descend without the mast of the carriage 4 having to to be moved.

Comme représenté sur la Figure 5C, le godet 9 est ensuite amené à pivoter davantage pour le creusement de la tranchée. Pour cela, le premier vérin 7 est amené à pivoter à l'opposé du chariot 4 autour du quatrième axe A4 de pivotement horizontal et la tige 7b du premier vérin 7 est étendue. Un tel déplacement du premier vérin 7 provoque la rotation du godet 9 autour du premier axe A1 de pivotement horizontal, en direction du chariot 4.As shown on the Figure 5C , the bucket 9 is then rotated further to dig the trench. For this, the first cylinder 7 is pivoted away from the carriage 4 about the fourth horizontal pivot axis A4 and the rod 7b of the first cylinder 7 is extended. Such a displacement of the first jack 7 causes the bucket 9 to rotate about the first axis A1 of horizontal pivoting, towards the carriage 4.

Une fois la tranchée creusée, les matériaux contenus dans le godet 9 sont déchargés à côté de la tranchée par déplacement en translation du second bras 6 le long des rails de guidage 21, 22 du support de montage 2.Once the trench has been dug, the materials contained in the bucket 9 are discharged next to the trench by translational displacement of the second arm 6 along the guide rails 21, 22 of the mounting support 2.

Ainsi, le dispositif de terrassement 1 de la présente invention permet à la fois des opérations de creusement de trou et de déchargement de matériaux sans avoir à déplacer le chariot 4 portant le dispositif 1.Thus, the earth moving device 1 of the present invention allows both hole digging and material unloading operations without having to move the carriage 4 carrying the device 1.
