- a parallelogram adjusts the tilt forward.
- the axis (3) is substantially perpendicular to the ground.
- the height adjustment is carried out in a conventional manner by means of a cylinder and a joint.

- the device according to the invention provides means for automatic folding the movable brush (20) under the chassis of the vehicle, for example in the event of shock causing contact between the front brush and the rear brush.
- said means can comprise a gas compass (30), connecting the axis (23) of the brush drive motor (20), at the joint (18) near the axis of rotation (13) of the brush (10).
- the brushes (10, 20) are rotated in the direction A - B, i.e. from outside to inside.
- the rotation of the brushes causes a withdrawal movement and thus eliminates any risk of shock that could damage or distort the device.
- the compass (30) operates under a very low control pressure, so that in the event of impact, the brush (20) pushes the cylinder (14) on the arm (26) while folding against the other brush. By the meaning of rotation of the brushes, this kinematics then causes the reopening of the cylinder (14) and the corresponding withdrawal of the brush (20) under the chassis.
- the scanning device brings many advantages, due to the characteristic layout of the brooms which compose it.
- the scanning area is much larger than in the conventional devices.
- the device is light and does not obstruct vehicle performance and safety.
Description
La présente invention concerne un dispositif de balayage pour véhicule de voirie, de type balayeuse automobile ou tractée à châssis. Elle concerne également les véhicules équipés d'un tel dispositif.The present invention relates to a scanning device for a vehicle road, sweeper type automobile or towed chassis. It also concerns vehicles fitted with such a device.
Les balayeuses automobiles urbaines ou industrielles de type connu comportent sur l'avant ou sur le côté deux balais à brosses rotatives, réglables autour d'un axe vertical passant. Chaque balai est relié à la partie avant du véhicule au moyen d'un support formé de deux bras articulés autour d'un axe vertical. Une buse d'aspiration est placée sous le châssis du véhicule, en retrait des brosses, et communique avec une cuve réceptrice.Urban or industrial automobile sweepers of known type have two rotating brushes on the front or on the side, adjustable around a passing vertical axis. Each broom is connected to the front part of the vehicle by means of a support formed by two arms articulated around a vertical axis. A suction nozzle is placed under the vehicle chassis, set back from the brushes, and communicates with a tank receptor.
Cette solution présente plusieurs inconvénients.This solution has several drawbacks.
De par leur mouvement, les balais ramènent les déchets et salissures vers le centre du véhicule, afin qu'ils puissent être aspirés par la buse puis envoyés dans la cuve.By their movement, the brushes bring the waste and dirt to the center of the vehicle, so they can be sucked in through the nozzle then sent into the tank.
De ce fait, le recouvrement de la chaussée par les balais est imparfait. Des salissures peuvent passer entre la buse et les balais et ainsi ne pas être aspirées.Therefore, the covering of the roadway by the brushes is imperfect. of the dirt can pass between the nozzle and the brushes and thus not be sucked.
De plus, les balais ne peuvent être déplacés vers l'extérieur du véhicule et la zone couverte est donc limitée.In addition, the brushes cannot be moved outside the vehicle and the area covered is therefore limited.
Enfin, en cas de chocs ou si l'un des balais heurte un obstacle, sur la chaussée ou sur le côté, le dispositif risque d'être endommagé ou faussé.Finally, in the event of impact or if one of the brushes hits an obstacle, on the road or side, the device may be damaged or distorted.
Diverses solutions ont été proposées pour remédier à ces inconvénients. et permettre la recherche de déchets bien au-delà du gabarit du véhicule, sans risque pour le matériel ou les personnes.Various solutions have been proposed to remedy these drawbacks. and allow the search for waste far beyond the vehicle size, without risk to equipment or people.
Une des solutions proposées consiste à monter un dispositif de balayage supplémentaire à l'avant du véhicule, appelé troisième balai. Celui-ci est dans la plus part des cas totalement indépendant du double dispositif de balayage placé à proximité des moyens d'aspiration des déchets. Il a pour fonction de ramener les déchets se trouvant à une distance trop importante de la double brosse.One of the solutions proposed consists in mounting a scanning device additional at the front of the vehicle, called the third broom. It is in most cases completely independent of the dual sweep placed near the waste suction means. He has for function of bringing the waste which is too far away double brush.
Cette solution n'est pas pleinement satisfaisante.This solution is not fully satisfactory.
Le troisième balai se déplace dans le plan horizontal, de la gauche vers la droite. Les moyens utilisés pour le piloter, qu'ils soient mécaniques, électriques, hydrauliques ou pneumatiques, doivent être distincts de ceux permettant de contrôler la double brosse.The third broom moves in the horizontal plane, from left to the right. The means used to control it, whether mechanical, electric, hydraulic or pneumatic, must be separate from those to control the double brush.
Cette contrainte diminue sensiblement la facilité et le confort d'utilisation de l'ensemble.This constraint significantly reduces the ease and comfort of using all.
De plus, l'amplitude du mouvement du troisième balai est source de surcoût, et aussi de danger pour les passants qui risquent d'être heurtés par les éléments mécaniques de la structure. Ces éléments mécaniques étant exposés aux chocs, l'ensemble est fragilisé, d'où un coût d'entretien plus important.In addition, the range of motion of the third broom is a source of additional cost, and also of danger for passers-by who risk being struck by the mechanical elements of the structure. These mechanical elements being exposed to shocks, the assembly is weakened, resulting in a maintenance cost most important.
L'utilisation de ce type de dispositif a pour conséquence une augmentation sensible de la longueur du véhicule, ce qui ne va pas dans le sens souhaité, qui est précisément de réduire au maximum l'emprise des engins sur la chaussée.The use of this type of device results in an increase sensitive to the length of the vehicle, which does not go in the right direction desired, which is precisely to minimize the grip of gear on the road.
Le poids de ce troisième balai est relativement élevé. Le montage en porte-à-faux sur la partie avant du véhicule a pour conséquence un déplacement du centre de gravité qui déséquilibre l'ensemble.The weight of this third brush is relatively high. Cantilever mounting on the front of the vehicle results in displacement of the center of gravity which unbalances the whole.
Enfin, cette construction engendre un important surcoût de fabrication, au regard des moyens de commande et d'entraínement, de la systématique, et des les matériaux utilisés.Finally, this construction generates a significant additional manufacturing cost, look at control and drive means, systematics, and of the materials used.
Une autre solution consiste à utiliser un balai rotatif monté à l'extrémité d'une flèche articulée, disposée à l'avant de l'engin de voirie. La flèche se déplaçant dans le plan latéral, de part et d'autre de l'axe longitudinal du véhicule, on peut ainsi couvrir en théorie une surface plus large que celle correspondant strictement à l'emprise de la balayeuse.Another solution is to use a rotary broom mounted at the end an articulated boom, located at the front of the road vehicle. The arrow stands moving in the lateral plane, on either side of the longitudinal axis of the vehicle, we can cover in theory a larger surface than that strictly corresponding to the sweeper's footprint.
Ce montage permet par ailleurs de désolidariser le balai supplémentaire du mécanisme d'entraínement. Le balai étant maintenu élastiquement, il offre moins de résistance aux chocs éventuels.This assembly also makes it possible to separate the additional brush from the drive mechanism. The broom being held resiliently, it offers less resistance to possible shocks.
Une telle disposition est décrite dans le brevet EP 641 894.Such an arrangement is described in patent EP 641,894.
Cette solution n'est pas non plus pleinement satisfaisante. En effet, elle ne permet pas de modifier le réglage du ou des balais en fonction de la configuration de la voie ou d'autres paramètres pouvant affecter l'efficacité du balayage. De plus, la couverture est imparfaite : de par l'amplitude de son mouvement, le balai ne pourra pas retenir tous les déchets, dont une partie ne sera donc pas aspirée. This solution is also not fully satisfactory. Indeed, it does not not allow you to change the setting of the brush (es) depending on the channel configuration or other parameters that may affect efficiency of the sweep. In addition, the coverage is imperfect: by the amplitude of its movement, the broom will not be able to retain all the waste, including one part will therefore not be vacuumed.
Le document US-A-4 754 521 montre un dispositif de balayage pour véhicule de voirie comportant plusieurs balais montés sous le châssis du véhicule et dont la position par rapport à la surface à traiter est réglable. Un premier balai est placé à l'arrière du véhicule, à proximité des moyens d'aspiration, et est fixé en position après réglage. Un deuxième balai, mobile dans le plan horizontal, est disposé en avant du premier balai. Les deux balais sont articulés entre eux par une structure en parallélogramme.US-A-4,754,521 shows a scanning device for road vehicle comprising several brushes mounted under the chassis of the vehicle and whose position relative to the surface to be treated is adjustable. A first broom is placed at the rear of the vehicle, near the means and is fixed in position after adjustment. A second broom, movable in the horizontal plane, is disposed in front of the first brush. The two brushes are hinged together by a parallelogram structure.
Le document DE 91 15 578 U décrit un dispositif de balayage composé de deux ensembles identiques disposés symétriquement de part et d'autre de l'axe longitudinal du véhicule. Chaque ensemble comporte un balai principal et un balai supplémentaire mobile, qui est articulé au balai principal par l'intermédiaire d'un bras. Des moyens sont prévus pour le repli automatique du balai supplémentaire en cas de contact accidentel avec un obstacle. Document DE 91 15 578 U describes a scanning device composed of two identical sets arranged symmetrically on either side of the longitudinal axis of the vehicle. Each set has a broom main and an additional movable broom, which is hinged to the broom main via an arm. Means are provided for the automatic folding of the additional broom in the event of accidental contact with an obstacle.
La présente invention se propose de remédier à ces inconvénients en réalisant un dispositif de balayage pour véhicule de voirie permettant un réglage précis de l'inclinaison, de l'écartement et de la hauteur de chacun des balais, de manière à couvrir une zone dépassant le gabarit du véhicule tout en évitant les conséquences résultant de chocs frontaux ou latéraux et en assurant une aspiration optimale des déchets.The present invention proposes to remedy these drawbacks by realizing a scanning device for road vehicle allowing a precise adjustment of the inclination, spacing and height of each brushes, so as to cover an area beyond the vehicle size while avoiding the consequences resulting from frontal or lateral impacts and ensuring optimal waste suction.
Ce but est atteint par l'association dans un dispositif de balayage d'un premier balai fixé en position après réglage et d'un second balai mobile relié au premier par une structure en parallélogramme, coopérant avec des moyens de repli dudit balai mobile comportant un compas à gaz et un vérin.This object is achieved by the association in a scanning device of a first brush fixed in position after adjustment and a second mobile brush connected to the first by a parallelogram structure, cooperating with folding means of said movable broom comprising a compass gas and a jack.
Le dispositif selon l'invention est caractérisé par la disposition spécifique des balais à l'avant dudit véhicule, et plus particulièrement par la structure de support du balai mobile.The device according to the invention is characterized by the specific arrangement brushes at the front of said vehicle, and more particularly by the support structure of the movable broom.
Avantageusement, le dispositif pourra comprendre deux ensembles identiques de deux balais, disposés symétriquement de part et d'autre de l'axe longitudinal du véhicule. Advantageously, the device may include two sets identical of two brushes, arranged symmetrically on either side of the longitudinal axis of the vehicle.
L'invention est décrite ci-après à l'aide d'un exemple non limitatif de réalisation, et en référence aux dessins annexés, dans lesquels
- la figure 1 est une vue de trois quart en élévation d'un dispositif selon l'invention comportant deux ensembles de deux balais,
- la figure 2 est une vue du dessus du dispositif représenté à la figure 1, les balais mobiles étant en position dépliés,
- la figure 3 représente le dispositif de la figure 2, les balais mobiles étant repliés,
- FIG. 1 is a three-quarter view in elevation of a device according to the invention comprising two sets of two brushes,
- FIG. 2 is a top view of the device shown in FIG. 1, the mobile brushes being in the unfolded position,
- FIG. 3 represents the device of FIG. 2, the mobile brushes being folded back,
En référence aux figures annexées, et plus particulièrement la figure 1, le dispositif de balayage selon la présente invention comporte deux ensembles de balais (1, 2) et (1', 2'), montables sous le châssis du véhicule, le premier balai de chaque ensemble étant placé à l'arrière dans le sens de déplacement du véhicule, à proximité des moyens d'aspiration, et le deuxième en amont du précédent.With reference to the appended figures, and more particularly FIG. 1, the scanning device according to the present invention comprises two sets of brushes (1, 2) and (1 ', 2'), mountable under the vehicle chassis, the first broom of each set being placed at the rear in the direction of movement of the vehicle, near the suction means, and the second upstream from the previous one.
En utilisation, l'ensemble est monté à demeure sous le châssis d'un véhicule de voirie, à proximité immédiate des moyens d'aspiration.In use, the assembly is permanently mounted under the chassis of a road vehicle, in the immediate vicinity of the suction means.
Les balais sont montés sur une structure comportant des moyens de réglage dans les trois directions, de telle sorte que chaque balai puisse être orienté en fonction des besoins vers l'avant ou sur les côtés, et en hauteur.The brushes are mounted on a structure comprising means for adjustment in three directions, so that each brush can be oriented as required forward or sideways, and in height.
Le réglage vers l'avant a pour but de positionner l'assiette du balai par rapport au sol et est en principe effectué une fois pour toute, par l'intermédiaire de rotules (4) agissant sur l'axe (3) des balais. Un parallélogramme permet d'ajuster l'inclinaison vers l'avant. L'axe (3) est sensiblement perpendiculaire au sol.The aim of the forward adjustment is to position the trim of the brush by ground level and is in principle done once and for all, by by means of ball joints (4) acting on the axis (3) of the brushes. A parallelogram adjusts the tilt forward. The axis (3) is substantially perpendicular to the ground.
Le réglage en hauteur est réalisé de manière classique au moyen d'un vérin et d'une articulation.The height adjustment is carried out in a conventional manner by means of a cylinder and a joint.
Le réglage latéral permet si nécessaire de balayer une portion de voirie extérieure qui ne serait pas exactement dans le même plan que l'ensemble de la voie, par exemple un caniveau incliné.The lateral adjustment allows to sweep a portion of roadway if necessary exterior which would not be exactly in the same plane as the whole of the track, for example an inclined gutter.
Les balais arrières (1, 1') sont disposés à proximité des moyens d'aspiration (non représentés) et sont reliés entre eux par deux barres latérales (8, 9), la barre inférieure (8) étant fixe et la barre supérieure (9) étant prévue pour régler l'inclinaison des balais (1, 1') par l'intermédiaire, par exemple, de rotules à pas inversé.The rear brushes (1, 1 ') are arranged near the means suction (not shown) and are interconnected by two bars lateral (8, 9), the lower bar (8) being fixed and the upper bar (9) being provided for adjusting the inclination of the brushes (1, 1 ') by means of, for example, inverted pitch ball joints.
En utilisation, ces deux balais sont fixés en position, après réglage initial de leur inclinaison comme exposé ci-dessus.In use, these two brushes are fixed in position, after initial adjustment of their inclination as explained above.
Les balais (2, 2') situés sur l'avant du dispositif, sont mobiles parallèlement au sol.The brushes (2, 2 ') located on the front of the device are movable parallel to the ground.
Les figures 2 et 3 illustrent le fonctionnement des balais.Figures 2 and 3 illustrate the operation of the brushes.
Comme indiqué ci-dessus, le dispositif tel que représenté sur les figures comporte quatre balais, mais est en fait composé de deux ensembles identiques, parfaitement symétriques autour de l'axe longitudinal du véhicule.As indicated above, the device as shown in the figures has four brooms, but is actually made up of two sets identical, perfectly symmetrical around the longitudinal axis of the vehicle.
Le mode de fonctionnement du dispositif sera décrit en référence à un seul de ces ensembles, mais il doit être bien compris que les explications données s'appliquent indifféremment à l'autre ensemble.The operating mode of the device will be described with reference to only one of these sets but it should be understood that the explanations given apply equally to each other.
Chaque balai est avantageusement constitué d'une brosse rotative fixée sur un axe (13), sensiblement perpendiculaire par rapport au sol.Each broom advantageously consists of a fixed rotating brush on an axis (13), substantially perpendicular to the ground.
La brosse (10) du premier balai (1) est positionnée à l'arrière du dispositif, dans le sens de déplacement du véhicule et à proximité des moyens d'aspiration.The brush (10) of the first brush (1) is positioned at the rear of the device, in the direction of movement of the vehicle and near the suction means.
La brosse (10) est reliée par une articulation (18) à un parallélogramme (19) contrôlant l'inclinaison latérale des balais (1, 2) par l'intermédiaire de deux bras (17', 17").The brush (10) is connected by a joint (18) to a parallelogram (19) controlling the lateral inclination of the brushes (1, 2) by means of two arms (17 ', 17 ").
L'ensemble formé par les bras (17', 17") est selon le cas relié directement aux moyens de fixation du dispositif au châssis du véhicule, lorsque le dispositif ne comporte qu'un ensemble de balayage droit ou gauche, ou à l'articulation correspondante sur la brosse située en regard, lorsque le dispositif comporte deux ensembles symétriques de part et d'autre de l'axe longitudinal du véhicule.The assembly formed by the arms (17 ', 17 ") is, as the case may be, directly connected to the means for fixing the device to the chassis of the vehicle, when the device has only one right or left scanning set, or the corresponding joint on the brush located opposite, when the device has two symmetrical assemblies on either side of the axis longitudinal of the vehicle.
La brosse (20) du deuxième balai (2) est positionnée en avant de la brosse (10) du premier balai (1).The brush (20) of the second brush (2) is positioned in front of the brush (10) of the first brush (1).
Un vérin (15) permet également de régler l'inclinaison latérale de la brosse (20).A cylinder (15) also makes it possible to adjust the lateral inclination of the brush (20).
Un bras transversal (26) est monté à une de ses extrémités sur l'axe (23) du moteur d'entraínement de la brosse (20). L'autre extrémité dudit bras est reliée à un parallélogramme (27), qui coopère avec le vérin (14) de la brosse arrière (10). Le parallélogramme (27) permet de régler la différence de hauteur entre balais avants et balais arrières, en fonction par exemple de leur degré d'usure respectifs ou de l'état de la chaussée.A transverse arm (26) is mounted at one of its ends on the axis (23) of the brush drive motor (20). The other end of said arm is connected to a parallelogram (27), which cooperates with the cylinder (14) of the rear brush (10). The parallelogram (27) makes it possible to adjust the difference height between front and rear brushes, depending for example their respective degree of wear or the condition of the roadway.
Grâce à la présence des deux points d'articulation (28, 29), on peut ainsi agir sur le positionnement latéral de la brosse (20).Thanks to the presence of the two points of articulation (28, 29), it is thus possible act on the lateral positioning of the brush (20).
En agissant sur le parallélogramme (27) de manière à l'écarter de l'axe longitudinal du véhicule, on repousse la brosse (20) vers l'extérieur, ce qui permet de balayer une surface située en dehors de la zone correspondant à l'emprise du véhicule sur la chaussée. Ceci est illustré à la figure 2.By acting on the parallelogram (27) so as to move it away from the axis longitudinal of the vehicle, the brush (20) is pushed outwards, which allows to sweep a surface located outside the corresponding zone the vehicle's hold on the road. This is illustrated in Figure 2.
Grâce à l'articulation (28) reliant le parallélogramme (27) et le bras (26), le déplacement de la brosse (20) reste sensiblement parallèle à celui du véhicule.Thanks to the articulation (28) connecting the parallelogram (27) and the arm (26), the displacement of the brush (20) remains substantially parallel to that of the vehicle.
A l'inverse, en agissant sur le vérin (14) de manière à le rapprocher de l'axe central du véhicule, on replie la brosse (20) vers l'intérieur, tout en conservant un déplacement parallèle à celui du véhicule.Conversely, by acting on the jack (14) so as to bring it closer to the axis central of the vehicle, the brush (20) is folded inwards, while keeping a movement parallel to that of the vehicle.
En utilisation normale, le dispositif adopte la position représentée à la figure 2. La brosse (20) est écartée et dépasse du châssis du véhicule vers l'extérieur. La position initialement définie est conservée en marche.In normal use, the device adopts the position shown in the figure 2. The brush (20) is spread and protrudes from the chassis of the vehicle towards outside. The initially defined position is kept on.
Si deux ensembles symétriques sont montés sous le châssis, la surface balayée sera particulièrement large, puisqu'elle couvrira la zone trapézoïdale formée par les quatre brosses (10, 10', 20, 20').If two symmetrical assemblies are mounted under the chassis, the surface swept will be particularly wide, since it will cover the area trapezoidal formed by the four brushes (10, 10 ', 20, 20').
Le dispositif selon l'invention prévoit des moyens pour le repli automatique de la brosse mobile (20) sous le châssis du véhicule, par exemple en cas de choc provoquant un contact entre la brosse avant et la brosse arrière.The device according to the invention provides means for automatic folding the movable brush (20) under the chassis of the vehicle, for example in the event of shock causing contact between the front brush and the rear brush.
Dans une telle situation, il est en effet très important de prévenir les conséquences d'un impact qui peuvent être très dommageables pour les brosses et l'ensemble de la structure.In such a situation, it is indeed very important to prevent consequences of an impact which can be very damaging to brushes and the whole structure.
Avantageusement, lesdits moyens peuvent comprendre un compas à gaz (30), reliant l'axe (23) du moteur d'entraínement de la brosse (20), à l'articulation (18) à proximité de l'axe de rotation (13) de la brosse (10).Advantageously, said means can comprise a gas compass (30), connecting the axis (23) of the brush drive motor (20), at the joint (18) near the axis of rotation (13) of the brush (10).
En fonctionnement normal, les brosses (10, 20) sont en rotation dans le sens A - B, c'est-à-dire de l'extérieur vers l'intérieur. En cas de contact accidentel entre les balais avant et arrière, par exemple suite à un impact, la rotation des brosses provoque un mouvement de repli et on élimine ainsi tout risque de choc qui serait susceptible d'endommager ou de fausser le dispositif.In normal operation, the brushes (10, 20) are rotated in the direction A - B, i.e. from outside to inside. In case of contact accidental between the front and rear brushes, for example following an impact, the rotation of the brushes causes a withdrawal movement and thus eliminates any risk of shock that could damage or distort the device.
Le compas (30) fonctionne sous une pression de commande très basse, de telle manière qu'en cas d'impact, la brosse (20) repousse le vérin (14) sur le bras (26) en se repliant contre l'autre brosse. De par le sens de rotation des brosses, cette cinématique provoque ensuite la réouverture du vérin (14) et le retrait corrélatif de la brosse (20) sous le châssis.The compass (30) operates under a very low control pressure, so that in the event of impact, the brush (20) pushes the cylinder (14) on the arm (26) while folding against the other brush. By the meaning of rotation of the brushes, this kinematics then causes the reopening of the cylinder (14) and the corresponding withdrawal of the brush (20) under the chassis.
Une fois l'obstacle absorbé, on pourra depuis le poste de conduite redéplier la brosse (20) vers l'extérieur en agissant simplement sur le vérin (14). Once the obstacle has been absorbed, it will be possible to redeploy from the driving position the brush (20) outwards by simply acting on the jack (14).
En conclusion, le dispositif de balayage selon la présente invention apporte de nombreux avantages, en raison de la disposition caractéristique des balais qui le composent.In conclusion, the scanning device according to the present invention brings many advantages, due to the characteristic layout of the brooms which compose it.
Il comporte moins de pièces en mouvement, ce qui réduit les risques de chocs et limite l'usure.It has fewer moving parts, which reduces the risk of impacts and limits wear.
Son coût de fabrication est extrêmement faible et il ne nécessite pratiquement pas d'entretien. Il offre tous les avantages des balais tirés sans leurs inconvénients.Its manufacturing cost is extremely low and it does not require practically no maintenance. It offers all the advantages of drawn brooms without their drawbacks.
La surface de balayage est beaucoup plus importante que dans les dispositifs classiques. Enfin, le dispositif est léger et n'obère pas les performances et la sécurité d'utilisation du véhicule.The scanning area is much larger than in the conventional devices. Finally, the device is light and does not obstruct vehicle performance and safety.
L'invention n'est pas limitée au mode de réalisation et de fonctionnement décrit ci-dessus. En particulier, les vérins et les compas pourront être remplacés par des moyens équivalents, par exemple des ressorts, comme défini par les revendications.The invention is not limited to the embodiment and operation described above. In particular, cylinders and compasses may be replaced by equivalent means, for example springs, as defined by the claims.
