Description

La présente invention a pour objet un véhicule combiné hydrocureur avec un dispositif d'enroulage et de déroulage automatique d'un flexible de nettoyage haute pression associé à un tuyau d'aspiration.The subject of the present invention is a combined water-purifying vehicle with a device for automatically winding and unrolling a high-pressure cleaning hose associated with a suction pipe.

Il existe actuellement des véhicules de nettoyage et de collecte d'effluents, travaillant par tournées, qui sont couramment nommés par les spécialistes combinés hydrocureurs.There are currently roadside cleaning and effluent collection vehicles that are commonly appointed by the combined water purifier specialists.

Un véhicule de ce type est à titre d'exemple décrit dans le document FR 2 840 234 .A vehicle of this type is for example described in the document FR 2 840 234 .

De tels véhicules, qui sont polyvalents, sont spécialement adaptés à effectuer différents types de nettoyage tels qu'à titre d'exemples le nettoyage de cuves à fuel ou de cuves de stations service ou encore le nettoyage de bacs à graisse ou de réseaux d'égouts.Such vehicles, which are versatile, are specially adapted to perform various types of cleaning such as for example the cleaning of fuel tanks or tanks of gas stations or the cleaning of grease traps or networks of sewers.

Ces véhicules qui doivent satisfaire à une réglementation très stricte sont constitués par un tracteur ou un porteur coopérant avec une citerne dont la partie interne est subdivisée en au moins deux compartiments, à savoir d'une part un premier compartiment ou cuve à boue équipé d'un fond ouvrant situé à l'arrière du véhicule et susceptible de coopérer avec une pompe à vide et avec un tuyau d'aspiration, et d'autre part un second compartiment ou cuve à eau susceptible de coopérer avec une pompe haute pression ainsi qu'avec un flexible de nettoyage.These vehicles, which must comply with very strict regulations, are constituted by a tractor or a carrier cooperating with a tank whose internal part is subdivided into at least two compartments, namely on the one hand a first compartment or mud tank equipped with an opening bottom located at the rear of the vehicle and capable of cooperating with a vacuum pump and with a suction pipe, and secondly a second compartment or water tank capable of cooperating with a high pressure pump and with a cleaning hose.

Dans un tel véhicule, la pompe à vide sert à diminuer la pression régnant dans la cuve à boue de façon à permettre l'aspiration, à l'aide du tuyau d'aspiration dont une extrémité plonge dans le produit à pomper tandis que l'extrémité opposée est raccordée à un tuyau de remplissage équipé d'une vanne de remplissage qui est montée à la partie externe de la citerne.In such a vehicle, the vacuum pump serves to reduce the pressure in the sludge tank so as to allow suction, using the suction pipe, one end of which is immersed in the product to be pumped while the opposite end is connected to a filling pipe equipped with a filling valve which is mounted to the outer part of the tank.

Le flexible de nettoyage haute pression est quant à lui équipé d'une tête de nettoyage haute pression.The high-pressure cleaning hose is equipped with a high-pressure cleaning head.

Il est à noter que dans le cas particulier du nettoyage de réseaux d'égouts ou de réservoirs de tels véhicules doivent pouvoir ajouter dans le milieu à traiter des quantités d'eau sous pression très importantes, pouvant atteindre 400 l/min. voire plus.It should be noted that in the particular case of cleaning sewage systems or tanks of such vehicles must be able to add in the medium to be treated very large amounts of water under pressure, up to 400 l / min. see more.

Dans les véhicules combinés hydrocureurs de ce type, les éléments permettant l'enroulage et le déroulage du flexible de nettoyage haute pression d'une part et du tuyau d'aspiration d'autre part sont totalement indépendants, ce qui est de nature à augmenter dans une large mesure la complexité et l'encombrement du véhicule.In combined hydrocuring vehicles of this type, the elements allowing the winding and unwinding of the high-pressure cleaning hose on the one hand and the suction pipe on the other hand are completely independent, which is likely to increase in a large extent the complexity and size of the vehicle.

Le document DE-U-20 2008 013 050 divulgue un véhicule avec les caractéristiques du préambule de la revendication 1.The document DE-U-20 2008 013 050 discloses a vehicle with the features of the preamble of claim 1.

La présente invention a pour objet de remédier à ces inconvénients en proposant un dispositif d'enroulage et de déroulage automatique du flexible de nettoyage haute pression d'un véhicule combiné hydrocureur de nature à permettre à regrouper ces éléments en un seul ensemble.
A cet effet, l'invention a pour objet un véhicule combiné hydrocureur avec les caractéristiques de la revendication 1.The object of the present invention is to remedy these drawbacks by proposing an automatic winding and unrolling device for the high-pressure cleaning hose of a combined water-purifying vehicle that makes it possible to group these elements into a single unit.
For this purpose, the subject of the invention is a combined water-treatment vehicle with the features of claim 1.

Selon l'invention, l'enrouleur de flexible est entrainé en rotation autour de son axe dans le sens de l'enroulement par un moteur d'actionnement et tourne en roue libre dans le sens du déroulement.According to the invention, the hose reel is rotated about its axis in the direction of winding by an actuating motor and rotates freely in the unwinding direction.

Inversement, le dérouleur de flexible est entrainé en rotation autour de son axe vertical dans le sens du déroulement par un moteur d'actionnement hydraulique en particulier par l'intermédiaire d'une chaine coopérant avec un ensemble de pignons et tourne en roue libre dans le sens de l'enroulement en étant entrainé par l'enrouleur de flexible.Conversely, the hose unwinder is rotated about its vertical axis in the direction of unwinding by a hydraulic actuating motor, particularly by means of a chain cooperating with a set of sprockets and freewheeling in the direction of the winding being driven by the hose reel.

Des galets de serrage permettent de maintenir constamment le flexible de nettoyage haute pression à la périphérie du tambour du dérouleur de flexible.Clamp rollers keep the high-pressure cleaning hose at the periphery of the drum of the hose reel.

Le dérouleur permet ainsi de guider et d'entrainer ce flexible de nettoyage vers le bras mobile sur lequel il est maintenu et guidé vers la zone de travail par un ensemble de galets fixés sur ce bras.The unwinder thus guides and drives the cleaning hose to the movable arm on which it is held and guided to the work area by a set of rollers fixed on the arm.

D'autres galets également fixés sur le bras télescopique permettent de guider et cl'entrainer le tuyau d'aspiration vers la zone de pompage.Other rollers also attached to the telescopic arm can guide and train the suction pipe to the pumping area.

Il est à noter, que de façon connue en elle-même, ce tuyau d'aspiration peut être stocké sur la citerne par différents moyens tels qu'enrouleurs de stockage, cassettes etc...It should be noted that in a known manner in itself, this suction pipe can be stored on the tank by various means such as storage reels, cassettes etc ...

La caractéristique essentielle du dispositif conforme à l'invention est liée, outre la mise en place du tuyau d'aspiration et du flexible de nettoyage haute pression sur un même bras télescopique articulé, à proximité de la zone de travail, au fait que ce bras télescopique est mobile en rotation autour d'un axe vertical confondu avec l'axe de rotation du dérouleur de flexible, ces deux rotations étant bien entendu indépendantes.The essential characteristic of the device according to the invention is related, in addition to the introduction of the suction pipe and the high pressure cleaning hose on the same articulated telescopic arm, near the working area, the fact that this telescopic arm is rotatable about a vertical axis coincident with the axis of rotation of the hose unwinder, these two rotations are of course independent.

En effet, grâce à ce montage, les mouvements du bras télescopique n'entrainent pas de déplacement du flexible de nettoyage haute pression entre le dérouleur et l'enrouleur, et pendant cette opération, ce flexible peut rester en contact avec le tambour du dérouleur qui est fixe par rapport à la citerne, ce bien que pendant ces mouvements la longueur entre l'extrémité du flexible de nettoyage, c'est-à-dire la tête de nettoyage haute pression et la seconde extrémité du bras télescopique articulé puisse varier.Indeed, thanks to this assembly, the movements of the telescopic arm do not cause movement of the high pressure cleaning hose between the unwinder and the reel, and during this operation, the hose can remain in contact with the unwinding drum which is fixed relative to the tank, although during these movements the length between the end of the cleaning hose, that is to say the high pressure cleaning head and the second end of the articulated telescopic arm may vary.

Ce montage permet ainsi d'éviter toute torsion ou surtension du flexible de nettoyage haute pression.This assembly thus makes it possible to avoid any torsion or overvoltage of the high-pressure cleaning hose.

Selon l'invention, le bras télescopique articulé peut avantageusement avoir une longueur pouvant varier de 1500 à 2000 mm., être mobile en rotation sur un angle de 180° à sa première extrémité par laquelle il est fixé à la citerne, autour de son axe vertical, et en outre susceptible d'être incliné de préférence de plus ou moins 20° voire plus par rapport à l'horizontale.According to the invention, the articulated telescopic arm can advantageously have a length that can vary from 1500 to 2000 mm., Be rotatable on an angle of 180 ° at its first end by which it is fixed to the tank, around its axis. vertical, and further likely to be inclined preferably plus or minus 20 ° or more relative to the horizontal.

Ces différents mouvements d'allongement, de montée/descente ou de rotation du bras télescopique qui n'entrainent pas de déplacement du flexible de nettoyage haute pression entre le dérouleur et l'enrouleur sont commandés par des systèmes de vérins.These different movements of elongation, rise / fall or rotation of the telescopic arm that do not cause movement of the high pressure cleaning hose between the unwinder and the reel are controlled by jack systems.

A titre d'exemple, l'allongement du bras télescopique peut être commandé par l'intermédiaire de deux vérins montés en série, sa rotation par rapport à son axe vertical par l'intermédiaire d'un seul vérin et son inclinaison par rapport à l'horizontale par l'intermédiaire de deux vérins montés en parallèle.By way of example, the extension of the telescopic arm can be controlled by means of two cylinders connected in series, its rotation relative to its vertical axis by means of a single jack and its inclination with respect to the horizontal through two cylinders connected in parallel.

Il est à noter que la possibilité d'inclinaison du bras télescopique par rapport à l'horizontale correspond à une caractéristique particulièrement avantageuse de l'invention dans la mesure où elle permet de positionner la seconde extrémité de ce bras à proximité immédiate de la zone de travail, en particulier juste au dessus de l'égout de façon à éviter toute interférence et tout frottement entre le flexible de nettoyage et l'arête supérieure de cette zone, permettant ainsi d'éviter le montage de dispositifs de protection complémentaires.It should be noted that the possibility of inclination of the telescopic arm relative to the horizontal corresponds to a particularly advantageous characteristic of the invention insofar as it makes it possible to position the second end of this arm in the immediate vicinity of the zone of especially at the top of the sewer in order to avoid any interference and friction between the cleaning hose and the upper edge of this area, thus avoiding the installation of additional protective devices.

Selon une autre caractéristique particulièrement avantageuse de l'invention, le bras télescopique est équipé d'un bras de guidage du flexible de nettoyage haute pression, articulé à sa seconde extrémité.According to another particularly advantageous feature of the invention, the telescopic arm is equipped with a guide arm of the high pressure cleaning hose, articulated at its second end.

Ce bras de guidage peut avantageusement être équipé au niveau de son extrémité libre de deux galets de guidage du flexible de nettoyage haute pression.This guide arm may advantageously be equipped at its free end with two guide rollers of the high pressure cleaning hose.

Un vérin de réglage peut permettre de faire varier sa position angulaire d'environ 40° par rapport à la seconde extrémité du bras télescopique.An adjusting cylinder can allow to vary its angular position of about 40 ° relative to the second end of the telescopic arm.

La présence de ce bras de guidage correspond à une caractéristique particulièrement avantageuse de l'invention dans la mesure où elle permet de désolidariser le flexible de nettoyage et le tuyau d'aspiration au niveau de la zone de travail, et donc d'optimiser les positions de ces deux éléments.The presence of this guide arm corresponds to a particularly advantageous characteristic of the invention insofar as it makes it possible to separate the cleaning hose and the suction pipe at the level of the working zone, and thus to optimize the positions of these two elements.

Selon l'invention, l'enrouleur de flexible qui est conçu de manière à permettre le stockage d'un flexible de nettoyage haute pression de grande longueur pouvant avoir différents diamètres est en règle gênérale monté à l'avant de la citerne, au niveau de la cuve à eau alors que le dérouleur de flexible ainsi que le bras télescopique sont avantageusement fixés sur le fond ouvrant de la cuve à boue qui a en règle générale une forme concave.According to the invention, the hose reel which is designed to allow the storage of a high-pressure cleaning hose of great length which can have different diameters is generally installed in the front of the tank, at the level of the water tank while the hose unwinder and the telescopic arm are advantageously fixed on the opening bottom of the sludge tank which generally has a concave shape.

L'implantation du bras télescopique sur un tel fond de forme concave permet de réduire à un minimum la largeur nécessaire au stockage.The implementation of the telescopic arm on such a concave bottom allows to reduce to a minimum the width required for storage.

Selon une autre caractéristique particulièrement avantageuse de l'invention ce fond ouvrant est équipé d'un bac permettant le stockage du flexible de nettoyage haute pression et du tuyau d'aspiration, ainsi que de tous les accessoires nécessaires au nettoyage.According to another particularly advantageous feature of the invention this opening bottom is equipped with a tray for storing the high-pressure cleaning hose and the suction pipe, as well as all the accessories necessary for cleaning.

Lors du transport, le flexible de nettoyage et le tuyau d'aspiration ainsi que ses accessoires sont positionnés dans ce bac de stockage, permettant ainsi de réduire notablement le temps nécessaire à la mise en oeuvre du matériel.During transport, the cleaning hose and the suction hose and its accessories are positioned in this storage bin, thus significantly reducing the time required for the implementation of the equipment.

Il est en outre à noter que la vidange de la cuve à boue nécessite l'ouverture du fond ouvrant de cette cuve et le bennage de celle-ci.It should also be noted that the emptying of the sludge tank requires opening of the opening bottom of this tank and the tipping thereof.

Or, lors de cette opération, le flexible de nettoyage ainsi que le tuyau d'aspiration et les différents accessoires positionnés dans le bac de stockage peuvent rester en place ce qui est de nature à simplifier notablement cette opération et à en réduire dans une large mesure la durée.However, during this operation, the cleaning hose and the suction pipe and the various accessories positioned in the storage bin can remain in place which is likely to significantly simplify this operation and to reduce to a large extent the duration.

Ce tambour 12 est entrainé en rotation dans le sens du déroulement par un moteur hydraulique 14, ce par l'intermédiaire d'une chaine 15 engrènant avec un pignon 16 monté co-axialement sur l'arbre de sortie du moteur 14 et d'une roue dentée 17 montée co-axialement sur ce tambour 12.This drum 12 is rotated in the direction of unwinding by a hydraulic motor 14, by means of a chain 15 meshing with a pinion 16 mounted co-axially on the output shaft of the motor 14 and a gear 17 mounted co-axially on this drum 12.

Comme représenté plus précisément sur la figure 5, le flexible de nettoyage haute pression réalise une boucle autour du tambour 12 et est maintenu sur la périphérie de ce tambour par un ensemble de galets de serrage 18.As represented more precisely on the figure 5 , the high-pressure cleaning hose loops around the drum 12 and is held on the periphery of this drum by a set of clamping rollers 18.

Il est à noter que l'enrouleur de flexible 7 qui est moteur dans le sens de l'enroulement du flexible de nettoyage haute pression 4 est entrainé en roue libre par le dérouleur de flexible 8 dans le sens du déroulement.It should be noted that the hose reel 7 which is driving in the winding direction of the high-pressure cleaning hose 4 is driven freely by the hose reel 8 in the direction of unwinding.

Au contraire le dérouleur de flexible 8 est moteur dans le sens du déroulement du flexible de nettoyage haute pression 4 mais est entrainé par l'enrouleur de flexible 7 dans le sens de l'enroulement.On the contrary the hose unwinder 8 is motor in the direction of unwinding of the high pressure cleaning hose 4 but is driven by the hose reel 7 in the direction of winding.

Selon les figures 1, 4 et 5, le bras télescopique articulé 9 est lui-aussi monté sur le fond ouvrant 2 du compartiment à boue 2b de la citerne 1 à une première de ses extrémités et est plus précisément constitué par l'association de plusieurs tronçons de bras 9.1, 9.2, 9.3, 9.4 mobiles télescopiquement les uns dans les autres de manière à permettre de faire varier sa longueur de 1600 mm.According to figures 1 , 4 and 5 the articulated telescopic arm 9 is also mounted on the opening bottom 2 of the sludge compartment 2b of the tank 1 at a first end and is more precisely constituted by the combination of several arm sections 9.1, 9.2, 9.3 , 9.4 movable telescopically into each other so as to allow its length to be varied by 1600 mm.

Ce déplacement est commandé par deux vérins 21 qui sont montés en série.This displacement is controlled by two jacks 21 which are mounted in series.

Ce bras télescopique 9 est également mobile en rotation sur 180° autour d'un axe vertical 19 monté co-axialement à l'axe de rotation vertical 13 du tambour 12 du dérouleur de flexible 8 indépendamment de cet axe comme représenté schématiquement par une double flèche sur la figure 5 ; cette rotation est commandée par un vérin non représenté.This telescopic arm 9 is also rotatable about 180 ° about a vertical axis 19 mounted co-axially to the vertical axis of rotation 13 of the drum 12 of the hose reel 8 independently of this axis as shown schematically by a double arrow on the figure 5 ; this rotation is controlled by a jack not shown.

Ce bras télescopique est par ailleurs monté pivotant autour d'un axe horizontal 20 de façon à pouvoir être incliné par rapport à l'horizontale comme schématisé par les doubles flèches représentées sur la figure 4.This telescopic arm is also pivotally mounted about a horizontal axis 20 so as to be inclined relative to the horizontal as shown schematically by the double arrows shown on the figure 4 .

Cette rotation permet une inclinaison de ce bras de plus ou moins 20° par rapport à l'horizontale et est commandée par deux vérins montés en parallèle qui ne sont pas représentés sur les figures.This rotation allows an inclination of this arm of plus or minus 20 ° relative to the horizontal and is controlled by two cylinders connected in parallel which are not shown in the figures.

Selon la figure 4, le bras télescopique 9 est équipé à sa seconde extrémité opposée à l'extrémité par laquelle il est monté sur le fond ouvrant 2 d'un bras de guidage 22 du flexible de nettoyage haute pression articulé sur celui-ci autour d'un axe 23.According to figure 4 , the telescopic arm 9 is equipped at its second end opposite to the end by which it is mounted on the opening bottom 2 of a guide arm 22 of the high pressure cleaning hose hinged thereto about an axis 23 .

Un vérin 24 permet une rotation angulaire de ce bras de guidage 22 par rapport à la seconde extrémité du bras télescopique 9 d'un angle de 40°.A jack 24 allows an angular rotation of the guide arm 22 relative to the second end of the telescopic arm 9 by an angle of 40 °.

Selon les figures 4 et 5, le tronçon de flexible de nettoyage haute pression 4 déroulé par le dérouleur de flexible 8 est appliqué contre le bras télescopique 9 et le bras de guidage 22 par un ensemble de galets 25 fixés sur ce bras.According to figures 4 and 5 , the section of high pressure cleaning hose 4 unwound by the hose unwinder 8 is applied against the telescopic arm 9 and the guide arm 22 by a set of rollers 25 fixed on the arm.

Deux de ces galets sont montés à l'extrémité du bras de guidage 22 comme représenté sur la figure 4.Two of these rollers are mounted at the end of the guide arm 22 as shown in FIG. figure 4 .

Selon les figures 1 à 5, le tuyau d'aspiration 5 est quant à lui également porté par le bras télescopique 9 mais peut être désolidarisé de celui-ci au niveau du bras de guidage 22.According to Figures 1 to 5 , the suction pipe 5 is also carried by the telescopic arm 9 but can be detached from the latter at the guide arm 22.
