Description
La présente invention concerne un dispositif d'aspiration prévu pour être utilisé sur des véhicules de voirie, plus particulièrement des véhicules tels que par exemple des balayeuses urbaines.The present invention relates to a suction device intended to be used on road vehicles, more particularly vehicles such as for example street sweepers.
Les véhicules de ce type se composent, pour l'essentiel, d'un châssis articulé ou non, comportant au moins deux essieux, associé à des moyens de nettoyage tels que des brosses ou des balais, des moyens d'aspiration, un réceptacle qui est en général une cuve, pour recevoir les résidus aspirés, et le cas échéant un réservoir d'eau de capacité suffisante, ainsi qu'un poste de commande qui est en général placé à l'intérieur d'une cabine.Vehicles of this type consist, for the most part, of an articulated chassis or not, comprising at least two axles, associated with cleaning means such as brushes or brooms, suction means, a receptacle which is generally a tank, to receive the sucked residues, and if necessary a water tank of sufficient capacity, and a control station which is usually placed inside a cabin.
Le châssis est composé d'une partie avant qui reçoit les moyens d'aspiration et d'une partie arrière qui reçoit la cuve ainsi que des éléments de motorisation. Les moyens d'aspiration associent une turbine d'aspiration et des éléments permettant d'assurer la collecte et le transfert des déchets aspirés jusqu'à la cuve.The chassis is composed of a front part which receives the suction means and a rear part which receives the tank as well as motorization elements. The suction means combine a suction turbine and elements to ensure the collection and transfer of waste sucked to the tank.
De manière connue, les moyens d'aspiration sont constitués d'un ou plusieurs conduits qui sont reliés à une ou plusieurs buses d'aspiration.In known manner, the suction means consist of one or more ducts which are connected to one or more suction nozzles.
Les déchets sont aspirés au sol grâce à une dépression qui est générée à l'intérieur de la cuve. Les conduits d'aspiration sont directement reliés par une de leurs extrémités à l'avant du châssis du véhicule, par l'intermédiaire d'une buse qui est disposée de manière à permettre la collecte des déchets sur l'avant ou sur les côtés, au moyen d'un système de brosses. Par leur extrémité opposée, les conduits d'aspiration rejoignent la cuve réceptrice en partie arrière du châssis du véhicule.The waste is sucked to the ground thanks to a depression that is generated inside the tank. The suction ducts are directly connected by one of their ends to the front of the vehicle frame, via a nozzle which is arranged to allow the collection of waste on the front or on the sides, by means of a system of brushes. By their opposite end, the suction ducts join the receiving tank at the rear of the chassis of the vehicle.
Ces modalités connues comportent un certain nombre d'inconvénients, qui viennent limiter ou obérer la fiabilité des opérations d'aspiration et des performances des buses.These known methods have a certain number of disadvantages which limit or limit the reliability of the suction operations and the performance of the nozzles.
En effet, les buses, qui doivent à la fois assurer l'étanchéité et le maintien des conduits d'aspiration, subissent diverses contraintes en raison des mouvements des différents éléments montés sur le châssis du véhicule,Indeed, the nozzles, which must both seal and maintain the suction ducts, are subject to various constraints due to the movements of the various elements mounted on the chassis of the vehicle,
Or, du fait des conditions dans lesquelles ils sont conduits à intervenir, les véhicules de voirie sont très dépendants de la configuration et de l'encombrement des voies. Ils peuvent ainsi être amenés à effectuer des virages fréquents et brusques ainsi que des mouvements de braquage comportant une forte amplitude, par exemple pour éviter un obstacle ou contourner un véhicule garé le long de la voie.However, because of the conditions in which they are led to intervene, the road vehicles are very dependent on the configuration and congestion of the tracks. They can thus be made to make frequent and sudden turns and steering movements with a high amplitude, for example to avoid an obstacle or bypass a vehicle parked along the track.
De ce fait, les buses d'aspiration subissent des chocs et des contraintes répétés, ce qui peut abréger leur durée d'utilisation.As a result, the suction nozzles experience repeated shocks and stresses, which can shorten their life.
Diverses solutions ont déjà été envisagées pour remédier à ces inconvénients.Various solutions have already been envisaged to overcome these disadvantages.
Ainsi, on connaît des buses réalisées en métal et recouvertes à l'intérieur de polyuréthanne. Il existe également des buses intégralement réalisées en polyuréthanne coulé, ce qui nécessite un outillage et des moules particulièrement complexes et coûteux.Thus, nozzles made of metal and covered with polyurethane inside are known. There are also nozzles integrally made of cast polyurethane, which requires tools and molds particularly complex and expensive.
Le document
Cette solution n'est pas pleinement satisfaisante, dans la mesure où la buse ne remplit pas ici une double fonction d'étanchéité et de rigidification de la partie inférieure du conduit. Les points de liaison entre les éléments tubulaires rigides et les parties coudées constituent des zones d'affaiblissement, avec des pertes possibles d'étanchéité.This solution is not fully satisfactory, insofar as the nozzle does not fulfill here a dual function of sealing and stiffening of the lower part of the duct. The connection points between the rigid tubular elements and the bent portions constitute areas of weakness, with possible leakage losses.
De surcroît, les parties coudées subissent une forte abrasion à raison des sables et déchets granuleux qui sont aspirés, d'où une usure rapide.In addition, the bent parts undergo a high abrasion due to sands and granular waste that are sucked, resulting in rapid wear.
Le document
Le problème que se propose de résoudre l'invention est d'améliorer l'étanchéité et la résistance des buses d'aspiration utilisées sur les véhicules de voirie.The problem to be solved by the invention is to improve the sealing and the resistance of the suction nozzles used on the road vehicles.
L'invention propose un dispositif d'aspiration comportant une buse fixée sur l'essieu avant d'un véhicule et actionnée par au moins un vérin et dont le déplacement est limité par un rail de guidage, des éléments de rigidification extérieurs pouvant être prévus.The invention provides a suction device comprising a nozzle attached to the front axle of a vehicle and actuated by at least one jack and whose movement is limited by a guide rail, external stiffening elements may be provided.

En référence aux figures annexées, et plus particulièrement la
Le châssis (2) comporte une partie avant (2') et une partie arrière (2"). Les moyens d'aspiration sont disposés sous la partie avant (2'). Une cuve (4) de réception des déchets aspirés est positionnée sur la partie arrière (2").The frame (2) comprises a front part (2 ') and a rear part (2' '), the suction means are arranged under the front part (2') and a tank (4) for receiving the sucked waste is positioned. on the back (2 ").
Le dispositif d'aspiration est composé d'au moins une buse d'aspiration (5) qui est fixée sur l'essieu avant (6) du véhicule et reliée par son extrémité supérieure à un conduit (7) prévu pour convoyer les déchets aspirés.The suction device is composed of at least one suction nozzle (5) which is fixed on the front axle (6) of the vehicle and connected at its upper end to a duct (7) intended to convey the aspired waste. .
La buse (5) est actionnée au moyen d'au moins un bras de vérin (8) comportant deux axes de rotation (8' et 8") et dont le déplacement est limité par un rail de guidage (9).The nozzle (5) is actuated by means of at least one jack arm (8) having two axes of rotation (8 'and 8 ") and whose movement is limited by a guide rail (9).
Grâce à cette modalité, la buse peut être montée de 200 mm avec un mouvement quasiment rectiligne pour se plaquer contre l'essieu, tout en garantissant une garde au sol maximum, la structure de la buse étant fixée sous l'essieu.Thanks to this mode, the nozzle can be mounted 200 mm with a virtually straight movement to press against the axle, while ensuring maximum ground clearance, the structure of the nozzle being fixed below the axle.
Le vérin (8) est fixé par une de ses extrémités sur l'essieu avant (6) du châssis (2) du véhicule. Le véhicule comportant des suspensions à assiette variable, on est ainsi assuré que la buse (5) reste toujours en contact avec l'essieu (6).The cylinder (8) is fixed by one of its ends on the front axle (6) of the chassis (2) of the vehicle. The vehicle having suspensions variable trim, it is thus ensured that the nozzle (5) always remains in contact with the axle (6).
En phase d'utilisation, l'opérateur doit depuis la cabine (3) contrôler les mouvements de montée et de descente de l'ensemble d'aspiration formé par la buse (5) et le conduit (7), lorsque ladite buse (5) est en contact avec le sol pour permettre l'aspiration des déchets et particules.In the use phase, the operator must from the cabin (3) control the upward and downward movements of the suction assembly formed by the nozzle (5) and the duct (7), when said nozzle (5 ) is in contact with the ground to allow the aspiration of the waste and particles.
Plus précisément, l'opérateur doit en phase de fonctionnement actionner le conduit (7) et la buse (5) pour amener celle-ci en position basse, à proximité immédiate du sol afin que les déchets puissent être aspirés puis acheminés vers la cuve (4) au travers du conduit (7).More precisely, the operator must, in the operating phase, actuate the duct (7) and the nozzle (5) to bring it down into the immediate vicinity of the ground so that the waste can be sucked up and then conveyed to the tank ( 4) through the conduit (7).
Par contre, lorsque le dispositif n'est pas en cycle d'utilisation, l'opérateur remontera la buse (5), à la fois pour éviter une usure prématurée et prévenir tout risque de choc ou d'accrochage.By cons, when the device is not in use cycle, the operator will reassemble the nozzle (5), both to prevent premature wear and prevent any risk of shock or snagging.
La buse (5) pourra être contrôlée par un clapet anti-retour (non représenté) prévu pour la maintenir en position haute en cas de chute de pression à l'intérieur du vérin (8).The nozzle (5) may be controlled by a non-return valve (not shown) provided to maintain it in the up position in case of pressure drop inside the cylinder (8).
Le mouvement de remontée de la buse (5) est contrôlée au moyen de la pression disponible de la pompe de gavage (non représentée) du circuit hydraulique du véhicule, ou d'autres sources de pression, comme par exemple un circuit de pression d'huile.The upward movement of the nozzle (5) is controlled by means of the available pressure of the booster pump (not shown) of the hydraulic circuit of the vehicle, or other sources of pressure, such as a pressure circuit of oil.
En effet le véhicule ayant un avancement hydrostatique, une pression constante de 26 bars est disponible.Indeed the vehicle having a hydrostatic progress, a constant pressure of 26 bar is available.
En position de repos, la pression sur la tige du vérin (8) est toujours maintenue, et donc la buse (5) est toujours poussée vers le haut. En cas d'arrêt du moteur thermique, et donc de chute de la pression de gavage, le clapet anti-retour permettra que la buse (5) reste en position haute.In the rest position, the pressure on the rod of the cylinder (8) is always maintained, and therefore the nozzle (5) is always pushed upwards. In case of stopping of the heat engine, and thus of falling of the pressure of feeding, the non-return valve will allow that the nozzle (5) remains in high position.
La buse d'aspiration (5) est réalisée par projection de polyuréthanne. Ainsi, on peut dissocier les fonctions d'étanchéité et de maintien.The suction nozzle (5) is made by polyurethane spraying. Thus, it is possible to separate the sealing and holding functions.
On plaque autour de la buse (5) des éléments de structure extérieurs formant un carcan qui assurera la fonction de maintien pour rigidifier le dispositif. Ces éléments de structure extérieurs pourront consister en une ou plusieurs pièces en tôle pliées disposées sur le pourtour de la buse (5), pour former le carcan. Dans ce cas, le polyuréthanne sera directement projeté dans le carcan formé par les tôles extérieures et fera ainsi fonction de moule perdu.Plates around the nozzle (5) are placed around external structural elements forming a yoke that will provide the holding function to stiffen the device. These external structural elements may consist of one or more folded sheet metal parts disposed around the periphery of the nozzle (5), to form the yoke. In this case, the polyurethane will be directly projected into the yoke formed by the outer sheets and thus act as a lost mold.
Dans le mode normal d'utilisation, la buse (5) est dirigée vers le bas pour aspirer les déchets au sol.In the normal mode of use, the nozzle (5) is directed downwards to suck up the waste on the ground.
Les déchets et particules sont ensuite convoyés par un conduit (7) prolongeant la partie supérieure de la buse (5) et rejoignant à l'opposé la cuve (4) de collecte des déchets.The waste and particles are then conveyed by a conduit (7) extending the upper part of the nozzle (5) and joining the opposite tank (4) for collecting waste.
La buse (5) est montée sur des roulettes (14) qui sont disposées sensiblement dans le prolongement de l'essieu (6) du véhicule de voirie.The nozzle (5) is mounted on rollers (14) which are arranged substantially in the extension of the axle (6) of the road vehicle.
Le dispositif se trouvant sous un véhicule comportant une direction articulée, il n'est pas nécessaire que les roulettes (14) soient mobiles, ce qui permet de limiter les dimensions de l'ensemble.The device being under a vehicle having an articulated direction, it is not necessary that the rollers (14) are movable, which limits the size of the assembly.
La partie avant de la buse (5) comporte une trappe (16) qui est actionnée par les obstacles rencontrés.The front part of the nozzle (5) comprises a hatch (16) which is actuated by the obstacles encountered.
Ainsi, lorsque la buse (5) rencontre un obstacle sur le sol, la trappe (16) s'ouvre, puis se refermera dès l'obstacle passé. La trappe (16) est formée d'une seule pièce.Thus, when the nozzle (5) encounters an obstacle on the ground, the hatch (16) opens, then closes once the obstacle past. The hatch (16) is formed in one piece.
La partie arrière de la buse peut être reliée à une alimentation en eau (non représentée) destinée à humidifier l'intérieur de la buse (5) pour faciliter la collecte et le transfert des déchets jusqu'à la cuve (4).The rear portion of the nozzle may be connected to a water supply (not shown) for moistening the interior of the nozzle (5) to facilitate the collection and transfer of waste to the tank (4).
Cette modalité permet d'éviter à la fois des écoulements d'eau vers le sol et un colmatage à terme de la buse (5).This modality makes it possible to avoid both water flows to the ground and a clogging of the nozzle (5).
En effet, en humidifiant les déchets à l'intérieur de la buse (5), et non pas dans le conduit (7) on assure un rinçage permanent de la buse (5) et on évite donc des risques de colmatage.Indeed, by moistening the waste inside the nozzle (5), and not in the conduit (7) ensures a permanent rinsing of the nozzle (5) and thus avoids the risk of clogging.
De plus, en plaçant l'alimentation en eau en arrière de la buse, on évitera toute projection d'eau vers le sol, puisque la plaque recevant le clapet est verticale.In addition, by placing the water supply behind the nozzle, it will avoid any water projection to the ground, since the plate receiving the valve is vertical.
