Abstract
Description
La présente invention concerne une structure de lavage pour véhicule de voirie du type comportant divers moyens pour assurer le nettoiement des chaussées et des bordures de voie par épandage ou projection de fluide, en particulier de l'eau et reliée directement à un bloc de distribution en eau unique associé à une cuve.The present invention relates to a washing structure for a vehicle roads of the type comprising various means for ensuring the cleaning of pavements and curbs by spreading or spraying fluid, in particular water and connected directly to a water distribution block unique associated with a tank.
Le nettoyage des voiries en milieu urbain se heurte à de nombreuses contraintes, en raison notamment de la configuration des voies, de la présence de véhicules en mouvement ou en stationnement et d'autres paramètres encore qui s'opposent à un traitement régulier et uniforme des surfaces. Ainsi, il est souvent nécessaire de prévoir au moins deux passages successifs sur une même zone, ce qui suppose souvent dans l'intervalle un passage du véhicule en atelier, par exemple pour régler ou modifier le positionnement des brosses ou des moyens de projection d'eau.Street cleaning in urban areas faces many constraints, in particular due to the configuration of the tracks, the presence of moving or parked vehicles and others parameters which oppose regular and uniform treatment of surfaces. So it is often necessary to plan at least two successive passages on the same area, which often implies in the interval a passage of the vehicle in workshop, for example to adjust or modify the positioning of brushes or water spraying means.
On connaít diverses modalités qui permettent isolément ou en combinaison d'effectuer des opérations de nettoyage de la voirie à partir d'un véhicule approprié.We know various modalities that allow individually or in combination perform road cleaning operations from a vehicle appropriate.
Ainsi, le brevet français n°2 702 397 décrit un dispositif de projection d'un fluide sous pression prévu pour être monté à l'arrière d'un véhicule de voirie, par l'intermédiaire de vérins permettant d'en régler la position dans le plan vertical et relié hydrauliquement audit véhicule par une conduite d'aspiration et une conduite d'alimentation en eau.Thus, French patent n ° 2,702,397 describes a device for projecting a pressurized fluid intended to be mounted at the rear of a vehicle roads, by means of jacks allowing to adjust the position in the vertical plane and hydraulically connected to said vehicle by a pipe and a water supply line.
Cette modalité ne permet que partiellement d'atteindre les buts recherchés. En effet, son utilisation reste limitée à une zone de faible surface localisée, le dispositif n'étant ni extensible, ni déplaçable, le seul mouvement possible se faisant dans le plan vertical à l'arrière du véhicule.This modality only partially achieves the desired goals. Indeed, its use remains limited to an area of small localized area, the device being neither extendable nor movable, the only possible movement taking place in the vertical plane at the rear of the vehicle.
De plus, le positionnement des conduites en arrière du véhicule ne permet en tout état de cause que de traiter les sols, et pas éventuellement des zones latérales comme par exemples des bordures de trottoirs. In addition, the positioning of the pipes behind the vehicle does not allow in any case only to treat the soil, and not possibly side areas such as, for example, curbs.
Enfin, il n'est pas possible de modifier la direction de travail une fois le dispositif en place.Finally, it is not possible to change the direction of work once the device in place.
Les solutions connues de l'art antérieur présentent un inconvénient commun, qui est l'impossibilité pour le chauffeur du véhicule d'assurer à la fois les tâches de conduite et de surveillance des opérations de lavage, en raison d'un champ de vision réduit, ce qui peut comporter des risques importants notamment lorsque le lavage est effectué avec un deuxième opérateur suivant ou accompagnant à pied le véhicule.The solutions known from the prior art have a drawback common, which is the impossibility for the driver of the vehicle to ensure the times the tasks of driving and monitoring washing operations, in due to reduced field of vision, which can be hazardous important especially when washing with a second operator following or accompanying the vehicle on foot.
La présente invention se propose de remédier à ces différents inconvénients en réalisant une structure de lavage pour véhicule de voirie, pouvant être adaptée facilement sur tout type d'engins existants sans modification de structure et permettant de travailler sur une très large surface tant vers l'avant que vers l'arrière en passant instantanément d'une zone de traitement à l'autre sans qu'il soit nécessaire d'immobiliser le véhicule ou d'effectuer des opérations de réglage en atelier.The present invention proposes to remedy these various drawbacks by providing a washing structure for a road vehicle, can be easily adapted to any type of existing machine without modification of structure and allowing to work on a very large surface both forwards and backwards passing instantly from one treatment area to another without the need to immobilize the vehicle or carry out adjustment operations in the workshop.
La structure de lavage selon l'invention est disposée sur la partie supérieure de la cabine d'un véhicule de voirie et comporte deux potences distinctes, orientées respectivement vers l'avant et vers l'arrière de ladite cabine, l'ensemble de ces éléments étant reliés directement à un bloc de distribution en eau commun et unique associé à une cuve à double paroi.The washing structure according to the invention is arranged on the part upper cabin of a road vehicle and has two brackets distinct, oriented respectively towards the front and rear of said cabin, all of these elements being connected directly to a block of distribution of common and single water associated with a double-walled tank.
La présente invention sera mieux comprise en référence aux dessins annexés, dans lesquels :

- la figure 2 est une vue rapprochée du dessus du véhicule de voirie représenté à la figure 1,
- la figure 3 est une vue de détail de la potence arrière de la structure selon l'invention,
- la figure 4 est une vue de détail de la potence avant, et
- la figure 5 est une vue schématique en éélvation de la cuve.
- FIG. 1 is a three quarter front view of a road vehicle equipped with a washing structure according to the present invention,
- FIG. 2 is a close-up view from above of the road vehicle shown in FIG. 1,
- FIG. 3 is a detailed view of the rear stem of the structure according to the invention,
- FIG. 4 is a detailed view of the front stem, and
- Figure 5 is a schematic elevational view of the tank.
En référence aux figures annexées, et plus particulièrement aux figures 1 et 2, la structure de lavage (1) selon la présente invention est montée sur un véhicule de voirie comportant un châssis recevant une cabine (2) et une cuve (30) associée à un tuyau (3) d'alimentation en eau.With reference to the appended figures, and more particularly to figures 1 and 2, the washing structure (1) according to the present invention is mounted on a road vehicle comprising a chassis receiving a cabin (2) and a tank (30) associated with a water supply pipe (3).
La structure de lavage (1) est composée de deux potences (10, 20), orientées respectivement, vers l'avant et vers l'arrière de la cabine (2) du véhicule. l'ensemble étant relié directement à un bloc de distribution en eau commun associé à une cuve.The washing structure (1) is composed of two brackets (10, 20), oriented respectively, towards the front and towards the rear of the cabin (2) of the vehicle. the whole being directly connected to a water distribution block common associated with a tank.
L'alimentation en eau est assurée au moyen d'un tuyau (3) que l'opérateur déroule à partir d'un enrouleur unique (non représenté) disposé à l'arrière de la cabine (2). Un pistolet de lavage (non représenté) sera monté à l'extrémité libre du tuyau (3).The water supply is ensured by means of a hose (3) that the operator unrolls from a single reel (not shown) arranged at the rear of the cabin (2). A washing gun (not shown) will be mounted at the free end of the pipe (3).
Cette disposition permet de n'utiliser qu'un seul enrouleur recevant la longueur de tuyau nécessaire. Dans les véhicules classiques, il est nécessaire, si l'on veut travailler en alternance à l'avant et à l'arrière, de prévoir deux enrouleurs distincts. De plus, l'enrouleur avant est alors situé en partie basse du véhicule, ce qui interdit tout travail en hauteur.This arrangement makes it possible to use only one reel receiving the length of pipe required. In conventional vehicles, it is necessary, if you want to work alternately at the front and at the rear, provide two separate reels. In addition, the front reel is then located in the lower part of the vehicle, which prohibits any work at height.
Le tuyau (3) sera relié à l'une ou l'autre des potences (10, 20), selon que l'on souhaite travailler vers l'avant ou vers l'arrière du véhicule.The pipe (3) will be connected to one or other of the brackets (10, 20), depending on whether you want to work forward or backward.
Ceci permet d'assurer une amplitude de travail de 80°, très supérieure à celle offerte par les véhicules ou dispositifs de type connu.This ensures a working amplitude of 80 °, much greater than that offered by vehicles or devices of known type.
La figure 3 montre la potence arrière (20) et la figure (4) représente la potence avant (10).Figure 3 shows the rear stem (20) and Figure (4) shows the front stem (10).
On précisera cependant que la potence avant (10) est constituée des mêmes éléments que la potence arrière (20). La description et les remarques faites ci-après au regard de la potence arrière (20) s'appliquent également à la potence avant (10). However, it will be noted that the front stem (10) is made up of same elements as the rear stem (20). Description and remarks made below with regard to the rear stem (20) apply also at the front stem (10).
Comme illustré à la figure 3, la potence arrière (20) est fixée par l'une de ses extrémités sur un support (20') fixé en rotation autour d'un axe vertical (21).As illustrated in FIG. 3, the rear stem (20) is fixed by one of its ends on a support (20 ') fixed in rotation about a vertical axis (21).
Le tuyau (3) passe sur une poulie (6) montée à l'extrémité fixe (21) de la potence (20) qui se prolonge par un tube en U (22) ouvert sur le dessus.The pipe (3) passes over a pulley (6) mounted at the fixed end (21) of the bracket (20) which is extended by a U-shaped tube (22) open on the top.
La poulie (6) fait office de guide pour permettre à l'opérateur d'introduire l'extrémité du tuyau (3) dans le tube (22) et le faire glisser jusqu'à l'extrémité libre (23) de la potence.The pulley (6) acts as a guide to allow the operator to introduce the end of the hose (3) in the tube (22) and slide it up the free end (23) of the bracket.
La potence arrière (20) comporte des moyens (24) pour assurer le maintien du tuyau (3) à l'intérieur du tube (22).The rear stem (20) includes means (24) for ensuring the maintenance of the hose (3) inside the tube (22).
Les moyens de maintien (24) sont composés d'un couvercle (25), relié par une charnière (26) à l'un des côtés du tube (22), d'une poignée (27) permettant de soulever ou de rabattre le couvercle (25) autour de la charnière (26), et une attache rapide (28) permettant de fixer le couvercle sur le côté du tube (22) opposé à celui recevant la charnière (26).The holding means (24) are composed of a cover (25), connected by a hinge (26) on one side of the tube (22), a handle (27) allowing the cover (25) to be raised or folded down around the hinge (26), and a quick coupler (28) for fixing the cover on the side of the tube (22) opposite to that receiving the hinge (26).
Cette modalité permet d'engager ou de dégager rapidement le tuyau (3). En effet, une fois celui-ci introduit dans le tube (22), il suffit de rabattre le couvercle (25) puis de le fixer au moyen de l'attache rapide (28).This mode makes it possible to quickly engage or disengage the hose (3). Indeed, once it is introduced into the tube (22), it suffices to fold the cover (25) then fix it by means of the quick coupler (28).
L'opérateur déroulera ensuite la longueur de tuyau nécessaire, sans que ledit tuyau ne puisse se dégager accidentellement de la potence.The operator will then unroll the necessary length of pipe, without said pipe cannot be released accidentally from the stem.
A l'inverse, le retrait du tuyau sera effectué simplement en ouvrant le couvercle (25).Conversely, the removal of the pipe will be carried out simply by opening the cover (25).
A l'extrémité libre (21) de la potence (20), on prévoit deux galets (29a, 29b) d'axe vertical, et un galet (29') d'axe horizontal, disposés respectivement de part et d'autre sur les côtés du tube (22), et à l'avant du tube.At the free end (21) of the bracket (20), two rollers (29a, 29b) are provided. of vertical axis, and a roller (29 ') of horizontal axis, disposed respectively of on both sides on the sides of the tube (22), and at the front of the tube.
Les galets (29a, 29b, 29') assurent le guidage du tuyau (3) une fois celui-ci déroulé, afin à la fois de faciliter son déplacement à l'intérieur du tube (22) et éviter une usure prématurée. The rollers (29a, 29b, 29 ') guide the pipe (3) once it unrolled, in order to both facilitate its movement inside the tube (22) and avoid premature wear.
On observera que le tuyau (3) est simplement maintenu à l'intérieur du tube ouvert (22), mais qu'il peut librement coulisser d'avant en arrière à l'intérieur de ce tube. Ceci permet à l'opérateur de tirer et dérouler la longueur de tuyau dont il a besoin pour effectuer les interventions souhaitées.It will be observed that the pipe (3) is simply held inside the tube open (22), but that it can freely slide back and forth at inside this tube. This allows the operator to pull and unroll the length of hose he needs to perform the interventions desired.
En position de travail, il est nécessaire de pouvoir relever l'extrémité de la potence arrière (20) pour faciiiter le passage du tuyau (3) par-dessus d'éventuels obstacles, comme par exemple des véhicules en stationnement, ou des conteneurs posés le long du trottoir.In the working position, it is necessary to be able to raise the end of the rear stem (20) to facilitate the passage of the pipe (3) over possible obstacles, such as vehicles in parking lot, or containers placed along the sidewalk.
Selon une forme possible de réalisation, on prévoit à cet effet un ressort à gaz (4) reliant l'un des côtés du support (20') à la paroi latérale du tube (22).According to a possible embodiment, a spring is provided for this purpose. gas (4) connecting one side of the support (20 ') to the side wall of the tube (22).
Le ressort (4) permet également de maintenir la potence (20) en position de repos lorsque celle-ci n'est pas utilisée.The spring (4) also makes it possible to maintain the stem (20) in the position of rest when not in use.
Le passage d'une position de travail arrière vers une position de travail avant s'effectue très simplement. Il suffit en effet de désolidariser le tuyau (3) de la potence arrière (20) pour le relier à la potence avant (10).Changing from a rear working position to a working position before is done very simply. It suffices to separate the pipe (3) of the rear stem (20) to connect it to the front stem (10).
Cette opération est à la fois très simple et rapide, puisqu'il suffit de déclipser le couvercle (25) et de tirer le tuyau (3) vers l'arrière.This operation is both very simple and quick, since it suffices to unclip the cover (25) and pull the hose (3) backwards.
Comme il ressort de la figure 4, la potence avant (10), qui est constituée des mêmes éléments que la potence arrière (20) telle que décrite ci-dessus, est fixée sur la partie avant du toit de la cabine (2) du véhicule.As shown in Figure 4, the front bracket (10), which is made of the same elements as the rear stem (20) as described above, is fixed on the front part of the roof of the cabin (2) of the vehicle.
Cependant, et contrairement à la potence arrière (20), la potence avant (10) n'est pas libre en rotation autour d'un axe.However, and unlike the rear stem (20), the front stem (10) is not free to rotate about an axis.
Comme précédemment décrit, le tuyau (3) passe sur une poulie (6) montée à l'extrémité arrière (21) de la potence (10) qui se prolonge par un tube en U (22) ouvert sur le dessus. As previously described, the pipe (3) passes over a pulley (6) mounted at the rear end (21) of the bracket (10) which is extended by a tube in U (22) open on the top.
La poulie (6) fait office de guide pour permettre à l'opérateur d'introduire l'extrémité du tuyau (3) dans le tube (22) et le faire glisser jusqu'à l'extrémité avant (23) de la potence.The pulley (6) acts as a guide to allow the operator to introduce the end of the hose (3) in the tube (22) and slide it up the front end (23) of the stem.
Des moyens (24) sont également prévus pour assurer le maintien du tuyau (3) à l'intérieur du tube (22), qui recevra un couvercle (25), relié par une charnière (26) à l'un des côtés du tube (22), une poignée (27) permettant de soulever ou de rabattre le couvercle (25) autour de la charnière (26), et une attache rapide (28) permettant de fixer le couvercle sur le côté du tube (22) opposé à celui recevant la charnière (26).Means (24) are also provided for securing the pipe (3) inside the tube (22), which will receive a cover (25), connected by a hinge (26) on one side of the tube (22), a handle (27) allowing lift or fold the cover (25) around the hinge (26), and a quick coupler (28) for fixing the cover on the side of the tube (22) opposite to that receiving the hinge (26).
La présence des galets d'extrémité (29a, 29b, 29') permet le déplacement dans le plan horizontal de l'extrémité du tuyau (3) qui dépasse au-delà du tube (22).The presence of the end rollers (29a, 29b, 29 ') allows the displacement in the horizontal plane of the end of the pipe (3) which protrudes beyond the tube (22).
Grâce à la division du support de lavage en deux potences placées respectivement à l'avant et à l'arrière du véhicule, il sera possible de travailler indifféremment dans l'une ou l'autre direction sans qu'il soit nécessaire de modifier le véhicule, donc de l'immobiliser au moins temporairement. De plus, selon cette modalité, l'opérateur sera à tout moment visible du conducteur, et pourra donc intervenir en toute sécurité.Thanks to the division of the washing support into two brackets placed respectively at the front and rear of the vehicle, it will be possible to work indifferently in either direction without it being necessary to modify the vehicle, therefore to immobilize it at least temporarily. In addition, according to this modality, the operator will be at all moment visible to the driver, and can therefore intervene safely.
La figure 5 illustre les particularités de la cuve à eau (30).Figure 5 illustrates the features of the water tank (30).
La cuve à eau (30) est réalisée en polyéthylène rotomoulé sous une faible épaisseur.The water tank (30) is made of rotomolded polyethylene under a low thickness.
Elle est recouverte d'une paroi ou enveloppe (31) en tôle d'acier, ce qui permet de lui conférer la rigidité appropriée, ainsi que de la résistance aux chocs. Cette modalité rend aussi possible l'application de peinture sur la cuve.It is covered with a wall or envelope (31) of sheet steel, which gives it the appropriate rigidity, as well as resistance to shocks. This method also makes it possible to apply paint to the tank.
La cuve (30) étant complètement insérée dans une enveloppe (31) en tôle d'acier, il ne sera plus nécessaire de teinter le polyéthylène dans la masse pour obtenir différentes couleurs en fonction des demandes. The tank (30) being completely inserted in a sheet metal envelope (31) of steel, it will no longer be necessary to dye the polyethylene in the mass to obtain different colors according to requests.
Cette solution permet aussi de réduire les coûts d'outillage, puisque le moule servant à réaliser la cuve sera moins complexe, beaucoup moins de matière étant utilisée.This solution also reduces tooling costs, since the mold used to make the tank will be less complex, much less material being used.
La cuve ainsi réalisée est plus résistante aux chocs et au vieillissement qu'une cuve classique en polyester ou qu'un ensemble de petites cuves réalisées par rotomoulage pour former une grande cuve.The tank thus produced is more resistant to impact and aging than a classic polyester tank or a set of small tanks made by rotational molding to form a large tank.
Comme il n'est pas nécessaire que l'enveloppe extérieure (31) soit étanche, l'assemblage sera facilité, et la cuve pourra être réalisée en en tôle normale, compatible avec des liquides oxydants.As it is not necessary for the outer casing (31) to be waterproof, assembly will be facilitated, and the tank can be made in normal sheet, compatible with oxidizing liquids.
La cuve (30) est réalisé d'une seule pièce par rotomoulage, de telle sorte que le réservoir intérieur (33) ne soit pas fermé en sortie de rotomoulage. L'intérieur de la cuve (30) comporte des moyens faisant fonction de brise lame pour réguler les déplacements du liquide lorsque le véhicule est en mouvement.The tank (30) is made in one piece by rotational molding, so that the internal tank (33) is not closed at the rotational molding outlet. The interior of the tank (30) comprises means acting as a breeze blade to regulate the movements of the liquid when the vehicle is in movement.
Selon une forme de réalisation préférentielle, le brise-lame est constitué par une croix médiane (32), obtenue par moulage.According to a preferred embodiment, the breakwater consists of a middle cross (32), obtained by molding.
Cette technique permet d'obtenir en une seule opération le réservoir et le brise lame, sans exiger l'insertion de pièces supplémentaires à l'intérieur du moule.This technique makes it possible to obtain in a single operation the reservoir and the breakwater, without requiring the insertion of additional parts inside the mold.
Un couvercle (34) en tôle fait fonction de trou d'homme, ce qui est obligatoire sur ce genre de réservoir. Le couvercle (34) est conçu pour laisser respirer le réservoir lorsqu'il se vide, l'eau s'écoulant étant alors canalisée par des chicanes (non représentées) prévues à cet effet.A sheet metal cover (34) functions as a manhole, which is mandatory on this kind of tank.
