Abstract
Description
La présente invention est relative à un engin destiné à creuser des tranchées dans le sol par fraisage.The present invention relates to a machine intended for digging trenches in the ground by milling.
On connaît déjà des engins de ce type qui comportent à leur partie inférieure deux tambours à axes parallèles horizontaux munis d'outils sur leur périphérie, qui sont entraînés en rotation en sens inverse,chacun par un moteur coaxial avec le tambour, et qui creusent des tranchées en désagrégeant progressivement dans le sol et en ramenant entre eux les matériaux ainsi produits qui sont ensuite aspirés par une pompe.There are already known machines of this type which have at their lower part two drums with horizontal parallel axes provided with tools on their periphery, which are rotated in opposite directions, each by a motor coaxial with the drum, and which hollow out trenches gradually disintegrating in the ground and bringing together the materials thus produced which are then sucked up by a pump.
Selon un mode de réalisation connu d'apres le document US-A-3.894.587, chaque tambour est constitué par deux demi-tambours supportés de part et d'autre d'une âme métallique plane de faible épaisseur qui est disposée verticalement, perpendiculairement à l'axe du tambour.According to an embodiment known from document US-A-3,894,587, each drum is constituted by two half-drums supported on either side of a flat metallic core of small thickness which is arranged vertically, perpendicularly to the axis of the drum.
Comme, lors de son travail, l'engin s'enfonce en raison de son poids au fur et à mesure de la désagrégation du terrain sous l'action des outils placés sur les tambours, il est indispensable pour travailler dans des terrains rocheux, que l'âme centrale soit d'une épaisseur aussi faible que possible, car les outils ne peuvent désagréger le terrain situé au dessous de l'âme centrale.As, during its work, the machine sinks due to its weight as the terrain disintegrates under the action of the tools placed on the drums, it is essential to work in rocky terrain, that the central core is as thin as possible, because the tools cannot disintegrate the ground located below the central core.
Comme par ailleurs, les tambours sont soumis lors de leur travail à des efforts très élevés et à des vibrations importantes, les moteurs, le plus souvent hydrauliques, dont le bâti est assujetti à l'âme centrale et dont l'axe supporte les demi-tambours, sont soumis à de telles contraintes qu'ils ont une durée de vie relativement courte.As in addition, the drums are subjected during their work to very high forces and significant vibrations, the motors, most often hydraulic, whose frame is subject to the central core and whose axis supports the half drums, are subjected to such constraints that they have a relatively short lifespan.
La présente invention est relative à un nouveau dispositif de montage des moteurs sur de tels engins qui présente l'avantage de conférer à la fois une plus grande rigidité à l'âme centrale et d'éviter que les moteurs ne soient eux-mêmes soumis aux contraintes et vibrations qui s'exercent sur les tambours.The present invention relates to a new device for mounting the motors on such vehicles which has the advantage of giving both greater rigidity to the central core and of preventing the motors from being themselves subjected to stresses and vibrations exerted on the drums.
De cette manière, grâce à l'invention, les efforts s'exerçant sur les outils sont directement transmis à l'âme centrale sans passer par le bâti du moteur dont le rôle est seulement de communiquer le couple qui entraîne le tambour.In this way, thanks to the invention, the forces exerted on the tools are directly transmitted to the central core without passing through the motor frame, the role of which is only to communicate the torque which drives the drum.
La présente invention a pour objet un engin du type précité, caractérisé par le fait que l'âme centrale qui supporte les deux demi-tambours est constituée par une plaque verticale traversée par une douille tubulaire creuse à axe horizontal, coaxiale avec le tambour, ladite douille recevant à son intérieur le moteur d'entraînement des demi-tambours, moteur qui est coaxial avec le tambour et dont le carter est verrouillé en rotation par rapport à la douille, un flasque étant assujetti à chacune des extrémités de la douille pour supporter les roulements des demi-tambours correspondantsThe subject of the present invention is a machine of the aforementioned type, characterized in that the central core which supports the two half-drums is constituted by a vertical plate traversed by a hollow tubular sleeve with horizontal axis, coaxial with the drum, said sleeve receiving inside it the half-drum drive motor, motor which is coaxial with the drum and the casing of which is locked in rotation relative to the sleeve, a flange being fixed at each end of the sleeve to support the bearings of the corresponding half-drums
Dans un mode de réalisation particulier, l'entraînement des demi-tambours est assuré par un arbre cannelé qui s'engage à la fois dans des cannelures situées à l'intérieur de l'axe du rotor du moteur et dans des orifices cannelés de deux plateaux situés de part et d'autre du moteur et solidaires en rotation chacun d'un demi-tambour.In a particular embodiment, the driving of the half-drums is ensured by a grooved shaft which engages both in grooves situated inside the axis of the rotor of the motor and in grooved orifices of two plates located on either side of the motor and integral in rotation each with a half-drum.
Dans une variante préférée de ce mode de réalisation de l'invention, les cannelures de l'arbre sont engagées dans les cannelures correspondantes de l'axe creux du moteur et dans les cannelures des plateaux avec un jeu suffisant pour faire en sorte que le seul effort transmissible par le moteur aux plateaux est constitué par le couple qui entraîne en rotation les demi-tambours.In a preferred variant of this embodiment of the invention, the splines of the shaft are engaged in the corresponding splines of the hollow axis of the motor and in the splines of the plates with sufficient clearance to ensure that the only force transmissible by the motor to the plates is constituted by the torque which drives the half-drums in rotation.
Dans une variante pouvant s'appliquer par exemple au cas où l'on désire entraîner le tambour à une vitesse inférieure à la vitesse de rotation du moteur (de manière à accroître la puissance du moteur en accroîssant sa vitesse de rotation), un train d'engrenage démultiplicateur peut être disposé à la place des plateaux entre les extrémités de l'arbre cannelé et les demi-tambours.In a variant which can be applied for example in the case where it is desired to drive the drum at a speed lower than the speed of rotation of the motor (so as to increase the power of the motor by increasing its speed of rotation), a train of The reduction gear can be arranged in place of the plates between the ends of the splined shaft and the half-drums.
Conformément à l'invention, il est également a vantageux d'utiliser un arbre cannelé creux à l'intérieur duquel on dispose une chambre de compensation à volume variable, (par exemple en élastomère), qui permet d'assurer l'équilibrage des pressions de part et d'autre des joints d'étanchéité.According to the invention, it is also advantageous to use a hollow splined shaft inside which there is a compensation chamber with variable volume (for example made of elastomer), which makes it possible to ensure pressure balancing on either side of the seals.
Dans le but de mieux faire comprendre l'invention on va en décrire maintenant à titre d'illustration et sans aucun caractère limitatif, deux modes de réalisation pris comme exemples et représentés sur le dessin annexé.
- La figure 1 est une vue schématique en élévation représentant la partie inférieure d'un engin du type de ceux auxquels s'applique l'invention.
- La figure 2 est une vue en coupe à plus grande échelle selon II-II de la figure 1.
- La figure 3 est une vue en coupe d'une variante du dispositif de la figure 2.
- La figure 4 est une vue en perspective de l'âme munie de sa douille conformément à l'invention.
- Figure 1 is a schematic elevational view showing the lower part of a machine of the type to which the invention applies.
- FIG. 2 is a sectional view on a larger scale along II-II of FIG. 1.
- FIG. 3 is a sectional view of a variant of the device of FIG. 2.
- Figure 4 is a perspective view of the core provided with its sleeve according to the invention.
On a représenté sur la figure 1 la partie inférieure du corps 1 de l'engin qui est muni de deux tambours 2 disposés au même niveau et tournant autour de deux axes parallèles dans le sens des flèches.There is shown in Figure 1 the lower part of the body 1 of the machine which is provided with two
Chacun des tambours 2 est constitué par deux demi-tambours disposés de part et d'autre d'une âme 3 assujettie à la partie inférieure de l'engin.Each of the
Les tambours 2 sont munis d'outils 4 dont la périphérie est délimitée schématiquement sur la figure 1 par des cercles en traits mixtes.The
Entre les deux tambours 2 se trouve situé l'orifice d'admission P d'une pompe aspirante (non représentée) qui remonte à la surface du sol les débris de terrain détachés par les outils 4 lors de la rotation de tambours.Between the two
On retrouve sur la figure 2 l'âme 3 qui est solidaire d'un plateau transversal 5 qui lui permet d'être solidement fixé à la partie inférieure du corps 1 de l'engin.Found in Figure 2 the
On a schématiquement représenté sur le dessin une canalisation 6 qui traverse l'âme 3 et qui amène au moteur l'énergie qui lui est nécessaire, cette énergie pouvant être avantageusement constituée par un fluide hydraulique mais pouvant être également constituée par exemple par de l'énergie électrique.There is schematically shown in the drawing a
Conformément à l'invention, l'âme 3 est munie d'une douille cylindrique 7 dont l'axe horizontal 8 est perpendiculaire au plan de l'âme 3.According to the invention, the
Le diamètre intérieur de la douille 7 correspond sensiblement au diamètre extérieur du moteur 9 qui est schématiquement représenté sur le dessin.The inside diameter of the
Un flasque 10 est assujetti par des vis (schématiquement représentées en traits mixtes par leurs axes) sur chacune des extrémités de la douille 7. Des vis 11 schématiquement représentées rendent solidaires le moteur 9 des flasques 10.A
Conformément à l'invention, ces vis 11 ont essentiellement pour fonction d'immobiliser le moteur 9 en rotation par rapport à la douille 7, les flasques 10 étant solidement fixés sur cette dernière par les vis dont il a été précédemment parlé.In accordance with the invention, these
L'axe creux 12 du moteur 9 comporte à son intérieur des cannelures 13 schématiquement représentées qui correspondent aux cannelures de l'arbre 14 qui assure l'entraînement des demi-tambours 2.The
Pour cela, les demi-tambours 2 sont montés sur les flasques 10 par des paliers 15, (par exemple des roulements à galets), un plateau cannelé 16 qui s'engage sur des cannelures 17 pratiquées aux extrémités de l'arbre 14 assurant la solidarisation en rotation des demi-tambours 2 avec l'arbre 14 et par conséquent avec l'axe 12 du moteur.For this, the half-
Dans le mode de réalisation de la figure 2, chaque plateau 16 est relié à la couronne 18 du demi-tambour 2 également par des cannelures 19 qui, grâce à leur jeu, évitent que tout effort autre que le couple d'entraînement soit transmis entre le demi-tambour 2, l'arbre 14 et le moteur 9.In the embodiment of Figure 2, each
On a enfin schématiquement représenté sur le dessin les joints d'étanchéité 20 qui interdisent aux débris provenant de l'action des outils 4 montés sur les tambours 2 de s'infiltrer jusqu'aux paliers 15.Finally, diagrammatically shown in the drawing are the
On comprend dans ces conditions que le mouvement de rotation transmis à partir du moteur 9 aux demi-tambours 2 par l'intermédiaire de l'arbre 14 (qui, grâce aux cannelures 13 et 17, est monté flottant, aussi bien par rapport au moteur 9 que par rapport aux demi-tambours 2), évite que tout effort autre que le couple d'entraînement des demi-tambours puisse se répercuter sur le moteur qui est par ailleurs tenu à l'abri de toutes les vibrations résultant du travail des outils .It is understood under these conditions that the rotational movement transmitted from the
En d'autres termes, on obtient, conformément à l'invention, une dissociation complète entre la fonction du moteur qui communique uniquement un couple de rotation aux demi-tambours et la fonction de l'âme qui reprend directement tous les autres efforts et supporte toutes les vibrations des tambours grâce au fait que les demi-tambours 2 sont directement montés par l'intermédiaire des paliers 15 sur les flasques 10 qui sont eux-mêmes solidement assujettis aux extrémités de la douille 7.In other words, in accordance with the invention, a complete dissociation is obtained between the function of the motor which communicates only a torque to the half-drums and the function of the core which directly takes up all the other forces and supports all the vibrations of the drums thanks to the fact that the half-
Par ailleurs, la douille 7 qui est disposée transversalement sur l'âme 3, a pour effet de raidir sensiblement cette dernière qui se trouve ainsi mieux en mesure de résister aux importantes contraintes de toutes natures qui sont inhérentes à ce type d'engin.Furthermore, the
Selon le mode de réalisation préféré qui est représenté sur la figure 2, l'arbre 14 est un arbre creux contenant à son intérieur une chambre 21 de volume variable qui permet, à la manière connue en soi, de réaliser un équilibrage des pressions de part et d'autre des joints 20 qui se trouvent ainsi protégés vis-à-vis des déformations de leurs garnitures.According to the preferred embodiment which is shown in FIG. 2, the
Dans le mode de réalisation représenté sur la figure 3, le dispositif présente la même structure, si ce n'est que les demi-tambours 2 sont entraînés en rotation par un train de pignons 22 tournant sur des axes 23, solidaires des flasques 10, ces pignons 22 engrenant, d'une part sur des dentures 19 réalisées à chaque extrémité de l'arbre 14, et d'autre part sur une denture 19 réalisée sur une couronne 18 solidaire de chaque demi-tambour 2.In the embodiment shown in FIG. 3, the device has the same structure, except that the half-
En choisissant les diamètres respectifs de l'arbre 14 et des pignons 22, il est possible de faire tourner les demi-tambours à une vitesse différente et en particulier à une vitesse inférieure à celle du moteur 9.By choosing the respective diameters of the
On a schématiquement représenté sur la figure 4 une vue en perspective de l'âme 3 munie de sa douille 7.FIG. 4 schematically shows a perspective view of the
On voit sur cette figure que l'axe de la douille 7 est horizontal et perpendiculaire à l'âme 3 qui comporte à la partie supérieure le plateau 5 qui lui permet d'être solidement fixé à la partie inférieure de l'engin.We see in this figure that the axis of the
Il est bien entendu que les modes de réalisation qui viennent d'être décrits ci-dessus ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiments which have just been described above have no limiting character and that they can receive any desirable modifications without departing from the scope of the invention.
En particulier, il est clair que dans la mesure où l'axe creux du moteur est désolidarisé des demi-tambours en ce qui concerne tous les efforts autres que le couple qui entraîne les demi-tambours en rotation, il est possible de réaliser par des moyens mécaniques autres que ceux qui ont été décrits l'accouplement entre l'arbre qui passe à l'intérieur de l'axe creux du moteur et les demi-tambours qui sont supportés par l'intermédiaire de paliers fixés sur les flasques assujettis aux extrémités de la douille.In particular, it is clear that since the hollow axis of the motor is separated from the half-drums with regard to all the forces other than the torque which drives the half-drums in rotation, it is possible to achieve by mechanical means other than those which have been described the coupling between the shaft which passes inside the hollow axis of the motor and the half-drums which are supported by means of bearings fixed on the flanges subject to the ends from the socket.
