CONDUIT D'ASPIRATION POUR VEHICULE DE VOIRIE A DIRECTION ARTICULEE LaSUCTION PIPE FOR ARTICULATED STEERING ROAD VEHICLE
présente invention concerne un conduit d'aspiration destiné à être utilisé sur un véhicule d'entretien de voirie à direction articulée, comme par exemple une balayeuse urbaine comportant un châssis articulé. The present invention relates to a suction duct for use on a road maintenance vehicle articulated steering, such as an urban sweeper with an articulated frame.
De manière classique, les véhicules de voirie comportent des moyens 10 d'aspiration qui permettent de prélever différents débris se trouvant sur la zone à traiter, puis de les convoyer au travers d'un conduit pour permettre leur collecte dans une cuve réceptrice, jusqu'à vidange. Typically, the road vehicles comprise suction means 10 which can collect different debris from the area to be treated, then convey them through a conduit to allow their collection in a receiving tank, up to emptying.
Les moyens d'aspiration sont associés à une turbine destinée à procurer un 15 flux d'air permettant de convoyer les débris depuis le sol jusqu'à la cuve au travers du ou des conduits, puis d'assurer la dépose et la répartition des débris à l'intérieur de la cuve, le principal problème à résoudre étant d'éviter tout colmatage en un point ou un autre de cette chaîne d'élément. The suction means are associated with a turbine intended to provide a flow of air making it possible to convey the debris from the ground to the tank through the duct or ducts, then to ensure the removal and distribution of the debris. inside the tank, the main problem to be solved is to avoid any clogging at one point or another of this element chain.
20 Il existe différents types de conduits d'aspiration qui permettent de remplir les différentes fonctions rappelées ci-dessus. There are different types of suction ducts which make it possible to fulfill the various functions mentioned above.
Pour l'essentiel, on distingue deux modalités principales. Essentially, there are two main modalities.
25 II existe en premier lieu des dispositifs d'aspiration qui utilisent des conduits souples. Cette modalité présente l'avantage de permettre l'utilisation de conduits d'une seule pièce, et d'autre part de faciliter leur mise en place et leur remplacement. In the first place there are suction devices which use flexible ducts. This modality has the advantage of allowing the use of ducts in one piece, and secondly to facilitate their implementation and replacement.
30 Par contre, cette solution présente un inconvénient majeur, dans la mesure où il n'est jamais possible avec un conduit souple d'obtenir un trajet parfaitement rectiligne des débris entre la buse d'aspiration et la cuve de récupération, puisque par définition, la structure souple du conduit sera perméable à toutes les déformations qui résultent d'événements extérieurs, 35 d'un parcours accidenté, ou tout simplement d'obstacles pouvant être rencontrés par le véhicule sur son chemin. Des virages répétés constituent également un facteur d'usure prématurée. By cons, this solution has a major drawback, in that it is never possible with a flexible conduit to obtain a perfectly straight path of debris between the suction nozzle and the recovery tank, since by definition the flexible structure of the conduit will be permeable to all the deformations that result from external events, from a rough path, or simply from obstacles that can be encountered by the vehicle on its way. Repeated turns are also a factor of premature wear.
Il en résulte d'une part une fragilité accrue du conduit, puisque celui subira toutes sortes de déformations pouvant provoquer une usure prématurée, voire des ruptures aux points de fixation d'extrémité, du coté respectivement, de la buse d'aspiration et de la cuve de collecte des déchets, ainsi que des risques accrus de bourrage ou de colmatage par suite d'accumulation de particules. This results on the one hand an increased fragility of the duct, since that will undergo all kinds of deformations may cause premature wear, even breaks at the end attachment points, on the side respectively, of the suction nozzle and the waste collection tank, as well as increased risk of jamming or clogging as a result of particle accumulation.
Un exemple de conduit d'aspiration de ce type est illustré dans le document CA 2 450 512, qui décrit un véhicule aspirateur mobile comportant de manière classique une cabine ainsi qu'une cuve pour la collecte des déchets, ainsi que des moyens d'aspiration qui sont associés à un conduit dont une partie est flexible, plus particulièrement la partie inférieure dirigée vers le bas et reliée à la buse d'inspiration. An example of a suction duct of this type is illustrated in document CA 2 450 512, which describes a mobile vacuuming vehicle conventionally comprising a cabin and a tank for the collection of waste, as well as suction means. which are associated with a duct of which a part is flexible, more particularly the lower part directed downwards and connected to the inspiration nozzle.
Cette modalité présente une faiblesse évidente, notamment dans la zone de jonction entre la partie flexible et la partie rigidifiée du conduit d'aspiration, dans la mesure où elle induit nécessairement une rupture de charge susceptible d'intervenir en ce point, avec des déformations et donc des risques de colmatage. This modality has an obvious weakness, especially in the junction zone between the flexible part and the stiffened part of the suction duct, insofar as it necessarily induces a load break that may occur at this point, with deformations and therefore risks of clogging.
Une seconde modalité connue de l'art antérieur consiste à utiliser des conduits d'aspiration rectilignes, composés d'une portion de tube rigide. Cette solution quoiqu'efficace, présente néanmoins un inconvénient à raison du positionnement des conduits. A second known method of the prior art consists in using rectilinear suction ducts, composed of a rigid tube portion. This solution, although effective, nevertheless has a drawback due to the positioning of the ducts.
En effet, lorsqu'un conduit de ce type est utilisé sur des véhicules de voirie montés sur des châssis articulés, le conduit passera forcément dans l'axe de rotation du châssis, ce qui veut dire que l'extrémité du conduit d'aspiration reliée à la buse en direction du sol viendra nécessairement se positionner en arrière de l'axe des roues, ou de l'essieu de la partie avant du châssis. Indeed, when a conduit of this type is used on road vehicles mounted on articulated frames, the conduit will necessarily pass in the axis of rotation of the frame, which means that the end of the suction pipe connected to the nozzle in the direction of the ground will necessarily be positioned behind the axis of the wheels, or the axle of the front part of the chassis.
Cette modalité oblige à positionner le dispositif d'aspiration très en arrière du véhicule, ce qui aura pour inconvénient d'empêcher toute visibilité de la part de l'opérateur. This mode requires positioning the suction device very behind the vehicle, which will have the disadvantage of preventing any visibility from the operator.
Par ailleurs, les performances se trouvent limitées de par le positionnement arrière du conduit, puisqu'une distance trop importante séparera la buse montée en extrémité du conduit et les moyens de collecte des déchets, avec donc des risques de perte sur les cotés. Furthermore, the performance is limited by the rear positioning of the duct, since too much distance will separate the nozzle mounted at the end of the duct and the waste collection means, with the risk of loss on the sides.
Pour remédier à cet inconvénient, on connaît des conduits d'aspiration rigides, qui sont composés de plusieurs parties ou portions de tube associées entre elles par des éléments de jonction, qui peuvent être soit des coudes ou encore des plaques de liaison. Une solution de ce type est par exemple décrite dans le document DE 87 07 111 ainsi que dans le document US 2 772 438. To overcome this drawback, rigid suction ducts are known, which are composed of several parts or portions of tube associated with each other by connecting elements, which may be either bends or connecting plates. A solution of this type is for example described in DE 87 07 111 and in US 2,772,438.
Cette solution ne permet pas de garantir une étanchéité totale. De plus, le recours à des éléments de jonction provoque une usure prématurée des 15 différents éléments, avec des risques de rupture inopinée. This solution does not guarantee complete sealing. In addition, the use of connecting elements causes premature wear of the various elements, with risks of unexpected rupture.
La présente invention se propose de remédier aux inconvénients mentionnés ci-dessus en réalisant un conduit d'aspiration formé d'une seule pièce et reliant directement Na buse d'aspiration à la partie inférieure 20 de la cuve de récupération des déchets sans recours à des éléments de liaison, tout en permettant une parfaite visibilité de la part de l'opérateur de par un positionnement en avant de l'axe des roues du véhicule. The present invention proposes to overcome the disadvantages mentioned above by providing a suction duct formed in one piece and directly connecting Na suction nozzle to the lower part 20 of the waste recovery tank without recourse to connecting elements, while allowing a perfect visibility on the part of the operator by positioning in front of the wheel axis of the vehicle.
L'invention sera mieux comprise au travers de la description donnée ci-25 après d'un véhicule équipé d'un conduit d'aspiration selon l'invention, et en référence aux figures annexées, dans lesquelles : The invention will be better understood from the description given below of a vehicle equipped with a suction duct according to the invention, and with reference to the appended figures, in which:
- la figure 1 est une vue d'ensemble d'un véhicule de voirie à direction articulée, montrant les différents composants et leur positionnement, - la figure 2 est une vue latérale en coupe d'un véhicule de voirie articulé, montrant le positionnement du conduit d'aspiration selon l'invention, la cuve de collecte des déchets étant en position abaissée de fonctionnement, 35 - la figure 3 est une vue du véhicule représentée à la figure 2 montrant le véhicule à l'arrêt, la cuve étant relevée pour permettre une vidange. 30 En référence aux figures annexées, et notamment la figure 1, on décrit un véhicule de voirie, qui de manière classique est composé d'un châssis (1), qui est ici articulé en deux parties, une partie avant (la) et une partie arrière (lb). La partie avant (la) du châssis reçoit une cabine (2) à partir de laquelle l'utilisateur peut piloter et diriger le véhicule et commander les différents accessoires afin de remplir la fonction de nettoyage d'une zone déterminée. FIG. 1 is an overview of an articulated-direction road vehicle showing the various components and their positioning; FIG. 2 is a sectional side view of an articulated public vehicle showing the positioning of the vehicle; suction pipe according to the invention, the waste collection tank being in the lowered operating position, - Figure 3 is a view of the vehicle shown in Figure 2 showing the vehicle stationary, the vessel being raised for allow emptying. With reference to the appended figures, and in particular FIG. 1, there is described a road vehicle, which conventionally consists of a chassis (1), which here is articulated in two parts, a front part (la) and a rear part (lb). The front part (la) of the chassis receives a cabin (2) from which the user can control and direct the vehicle and control the various accessories to perform the cleaning function of a specific area.
10 A l'avant de la cabine (2), et dans la partie inférieure à proximité du sol, se trouvent les moyens de nettoyage (3) qui sont ici constitués de deux brosses (3a et 3b) montées sur une structure (4) permettant leur déploiement et leur repli. At the front of the cabin (2), and in the lower part near the ground, are the cleaning means (3) which consist here of two brushes (3a and 3b) mounted on a structure (4). allowing their deployment and their withdrawal.
15 La partie arrière (1 b) du châssis reçoit une cuve (5) de collecte des déchets ainsi que les moyens d'aspiration des déchets prélevés sur le sol. The rear portion (1b) of the frame receives a tank (5) for collecting waste and the means for suctioning the waste taken from the ground.
La cuve (5) est à fond plat.The tank (5) has a flat bottom.
20 Les moyens d'aspiration sont composés, comme il apparaît sur la figure 2, d'une turbine (7) et d'un conduit (8) coopérant avec la turbine, dont l'une des extrémités comporte une buse (10) afin de permettre la collecte des déchets ramenés par les brosses (3a, 3b) vers l'axe central du véhicule, et dont l'autre extrémité débouche à 'intérieur de la cuve (5) de collecte des 25 déchets. The suction means are composed, as shown in FIG. 2, of a turbine (7) and a duct (8) cooperating with the turbine, one of whose ends comprises a nozzle (10) so as to to allow the collection of the waste brought by the brushes (3a, 3b) towards the central axis of the vehicle, and the other end of which opens into the interior of the tank (5) for collecting waste.
La figure 2 montre plus particulièrement le positionnement du conduit d'aspiration (8) selon l'invention. Figure 2 shows more particularly the positioning of the suction duct (8) according to the invention.
30 Ce conduit (8) d'aspiration est composé d'une portion tubulaire (8a) ouverte dont l'une des extrémités débouche vers le bas du véhicule pour être reliée à une buse d'aspiration (10), à proximité immédiate du sol. This suction duct (8) is composed of an open tubular portion (8a), one of its ends opening towards the bottom of the vehicle to be connected to a suction nozzle (10), close to the ground. .
L'autre extrémité est positionnée directement par sa partie ouverte contre 35 un orifice (11) ménagé dans la partie inférieure de la cuve (5), et dont le diamètre est inférieur ou égal à celui de la portion tubulaire (8a).5 Le conduit sera nécessairement positionné contre la paroi extérieure de la cuve, en correspondance l'orifice, de telle sorte qu'il ne sera pas nécessaire de prévoir d'autres moyens de liaison ou de jointage. The other end is positioned directly by its open part against an orifice (11) formed in the lower part of the tank (5), and whose diameter is less than or equal to that of the tubular portion (8a). duct will necessarily be positioned against the outer wall of the tank, in correspondence the orifice, so that it will not be necessary to provide other connecting means or jointing.
Selon une forme de réalisation préférentielle, la portion tubulaire (8a) du conduit d'aspiration (8) est rectiligne. According to a preferred embodiment, the tubular portion (8a) of the suction duct (8) is rectilinear.
Selon une forme de réalisation avantageuse, la portion tubulaire (8a) est sensiblement rigide. According to an advantageous embodiment, the tubular portion (8a) is substantially rigid.
Selon une variante de réalisation possible, on pourra prévoir à l'intérieur de la cuve (5) un déflecteur fixe (non représenté) disposé en correspondance de l'orifice (11), de manière à former un entonnoir lorsque la cuve (5) est en position abaissée, c'est-à-dire en position de fonctionnement. According to a possible variant embodiment, it is possible to provide inside the tank (5) a fixed deflector (not shown) arranged in correspondence with the orifice (11), so as to form a funnel when the tank (5) is in the lowered position, that is to say in the operating position.
La figure 3 montre le véhicule à l'arrêt, la cuve de collecte des déchets ayant été relevée afin de permettre da vidange. Figure 3 shows the vehicle stationary, the waste collection tank having been raised to allow emptying.
On constate que la cuve (5) se trouve en position quasi verticale et que 20 l'opération de relève a pu être effectuée sans que le tube d'aspiration (8) reliant la buse (10) à la cuve (5) n'ait été en quoique ce soit affecté ni déplacé ou déformé. It can be seen that the tank (5) is in a quasi-vertical position and that the relief operation could be carried out without the suction tube (8) connecting the nozzle (10) to the tank (5). has been in any way affected or displaced or distorted.
On remarque à l'examen des figures annexées que le conduit d'aspiration 25 (8) se termine très en avant des moyens d'aspiration, puisque son extrémité inférieure reliée à la buse (10) aboutit en avant de l'axe (9) de l'essieu avant du véhicule, ce qui constitue une différence fondamentale par rapport aux dispositifs connus. It will be noted on examining the appended figures that the suction duct 25 (8) ends very far ahead of the suction means, since its lower end connected to the nozzle (10) ends in front of the axis (9). ) of the front axle of the vehicle, which is a fundamental difference compared to known devices.
30 Cette modalité est possible parce que l'on utilise un conduit d'une seule pièce qui n'est pas solidaire de la cuve et qui n'est donc pas susceptible de subir des déformations ou des contraintes. This modality is possible because one uses a duct in one piece which is not integral with the tank and which is therefore not likely to undergo deformations or stresses.
Grâce à cette disposition, on peut réduire au strict minimum l'espace entre 35 l'extrémité du conduit d'aspiration et la zone active des moyens de prélèvement des débris en avant du véhicule. 15 En minimisant ainsi cet espace, on limite du mieux qu'il est possible les risques de perte des déchets sur les cotés. With this arrangement, it is possible to reduce to a strict minimum the space between the end of the suction duct and the active zone of the debris removal means in front of the vehicle. By minimizing this space, it limits as best as possible the risk of loss of waste on the sides.
En effet, les déchets qui sont rassemblés par les balais rotatifs sont dans un premier temps ramenés vers la partie centrale du véhicule afin de pouvoir être positionnés devant l'orifice d'entrée de la buse d'aspiration pour pouvoir ensuite être convoyés vers la cuve à travers le conduit d'aspiration. Indeed, the waste that is collected by the rotary brushes are initially brought to the central part of the vehicle so as to be positioned in front of the inlet port of the suction nozzle to then be conveyed to the tank through the suction duct.
Si un espace trop important sépare la zone active des balais de l'extrémité de la buse, le risque est que des déchets soient évacués vers les côtés du véhicule sans être aspirés, puisque l'effet de l'aspiration n'aura pas eu le temps de se faire sentir à raison du déplacement forcément lent de ce type de véhicules. If too much space separates the active zone of the brushes from the end of the nozzle, the risk is that waste is evacuated towards the sides of the vehicle without being sucked, since the effect of the suction will not have had the time to be felt because of the inevitably slow displacement of this type of vehicles.
Par ailleurs, un autre avantage important résulte dans le fait que grâce à ce positionnement très en avant de la buse et du conduit d'aspiration, l'opérateur présent dans la cabine aura une visibilité du dispositif qui pourra encore être améliorée, par exemple en prévoyant une lucarne dans le sol de la cabine. 30 35 Furthermore, another important advantage results from the fact that, thanks to this positioning very far ahead of the nozzle and the suction duct, the operator present in the cabin will have a visibility of the device which can be further improved, for example by providing a skylight in the floor of the cabin. 30 35
