Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne un véhicule hydrocureur sur lequel est monté un bras articulé permettant de guider au moins un tuyau d'aspiration.The invention relates to a water-cleaning vehicle on which is mounted an articulated arm making it possible to guide at least one suction pipe.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Actuellement, les véhicules hydrocureurs, du fait de leurs gabarits, sont amenés au voisinage d'un point d'intervention, en général une bouche d'égout ou équivalent. Ainsi, afin de pouvoir insérer au niveau du point d'intervention la buse d'aspiration située au bout d'un tuyau d'aspiration, les véhicules hydrocureurs comportent un bras articulé monté mobile sur la citerne de stockage. Par exemple, le document EP1 050 634 illustre un tel véhicule hydrocureur comportant un tel bras articulé. Le bras articulé, une fois reployé en position de conduite du véhicule hydrocureur, s'étend généralement le long de la citerne de stockage, au-dessus de celle-ci. Par conséquent, il occupe la quasi-totalité d'un volume important situé au-dessus de la citerne de stockage.Currently, water cleaning vehicles, because of their sizes, are brought to the vicinity of an intervention point, generally a sewer or equivalent. Thus, in order to be able to insert the suction nozzle located at the end of a suction pipe at the point of intervention, the water-cleaning vehicles include an articulated arm movably mounted on the storage tank. For example, the document EP1 050 634 illustrates such a hydrocurner vehicle comprising such an articulated arm. The articulated arm, once folded into the driving position of the hydrocurner vehicle, generally extends along the storage tank, above the latter. Consequently, it occupies almost all of a large volume located above the storage tank.

The drive 360 and guide 361 rollers are positioned at the proximal end 31, parallel to each other and extending apart from each other in a plane which is perpendicular to a longitudinal axis of the intermediate arm body 30. On the other hand, a tensioner system is positioned between the two drive rollers 360 and guide rollers 361 so as to allow the two rollers to move closer to each other by so as to ensure a support of the flexible suction pipe on the drive roller 360 in order to ensure good training of the latter during the implementation of the drive means of the flexible suction pipe. The other two guide rollers 362,363 are positioned substantially at the level of the distal end 34, one parallel to the other and at a distance from each other in a plane perpendicular to the longitudinal axis of the arm body intermediate 30.

De plus, le bras intermédiaire 3 comporte une chaine passe câbles/flexibles 32 qui, d'une part, est fixée et qui, d'autre part, s'étend latéralement d'un coté opposé du corps de bras intermédiaire 30 par rapport au châssis 35. Cette chaine passe câbles/flexibles 32 comporte, en particulier, un chaînon d'extrémité libre 321. Cette chaine passe câbles/flexibles 32 permet de faire cheminer un ensemble de câbles et de flexibles de commande des différents équipements du bras articulé 10 et, en particulier, du bras télescopique 4 qui sera décrit ci-après, et, ce, quelle que soit la configuration que puisse prendre le bras articulé 10.In addition, the intermediate arm 3 comprises a cable / flexible passage chain 32 which, on the one hand, is fixed and which, on the other hand, extends laterally on an opposite side of the intermediate arm body 30 with respect to the frame 35.

Au niveau de l'extrémité libre 42, le bras télescopique 4 comprend un élément de fixation 48 recevant le chaînon d'extrémité libre 321 de la chaîne passe câbles/flexibles 32. Ainsi, lors d'un mouvement du bras télescopique 4 par rapport au bras intermédiaire 3, la chaîne passe câbles/flexibles 32 se déforme de sorte que le chainon d'extrémité libre 321 suive le mouvement du bras télescopique 4. D'autre part, toujours au niveau de l'extrémité libre 42, le bras télescopique 4 comporte un troisième axe de fixation 47 de l'extrémité libre 370 du piston du vérin 37. L'extrémité libre 370 du piston de vérin 37 est alors montée libre à rotation selon cet axe sur le corps de bras télescopique 40 du bras télescopique 4.At the free end 42, the telescopic arm 4 comprises a fixing element 48 receiving the free end link 321 of the cable / flexible passage chain 32. Thus, during a movement of the telescopic arm 4 relative to the intermediate arm 3, the cable / flexible passage chain 32 is deformed so that the free end link 321 follows the movement of the telescopic arm 4. On the other hand, still at the level of the free end 42, the telescopic arm 4 comprises a third fixing pin 47 of the free end 370 of the piston of the cylinder 37. The free end 370 of the cylinder piston 37 is then mounted to rotate freely along this axis on the body of the telescopic arm 40 of the telescopic arm 4.

Toujours au niveau de l'extrémité libre 42 le bras télescopique 4 comporte un cadre support 45 fixé latéralement au corps de bras télescopique 40. Ce cadre support 45 est une structure qui comprend une deuxième série de galets de guidage 460,461,462,463 du tuyau flexible d'aspiration afin de lui faire subir un changement de direction de cheminement de l'ordre de 90° environ. Les galets de guidage 460 et 461 sont situés l'un parallèle à l'autre à distance l'un de l'autre dans un plan perpendiculaire à un axe longitudinal du corps de bras télescopique 40, tandis que les galets de guidage 462,463 sont positionnés l'un parallèle à l'autre à distance l'un de l'autre dans un plan perpendiculaire au plan contenant les galets de guidage 460 et 461 tout en étant parallèle à l'axe longitudinal du corps de bras télescopique 40.Still at the free end 42, the telescopic arm 4 comprises a support frame 45 fixed laterally to the telescopic arm body 40.

The guide rollers 460 and 461 are located parallel to each other at a distance from each other in a plane perpendicular to a longitudinal axis of the telescopic arm body 40, while the guide rollers 462,463 are positioned one parallel to the other at a distance from each other in a plane perpendicular to the plane containing the guide rollers 460 and 461 while being parallel to the longitudinal axis of the telescopic arm body 40.

D'autre part, toujours au niveau de l'extrémité libre 42, le bras télescopique 4 comporte des moyens d'entrainement du tuyau flexible haute pression. Les moyens d'entrainement du tuyau flexible haute pression comprennent, ici, une roue d'entrainement 43 du tuyau flexible haute pression mise en œuvre à l'aide d'un moteur 430 qui est ici un moteur de type hydraulique, par exemple. Des moyens tensionneur 431 du tuyau flexible haute pression sont aménagés de sorte à réaliser un bon appui du tuyau flexible haute pression sur la roue d'entrainement 43 afin d'en assurer un bon entrainement lors de la mise en œuvre des moyens d'entrainement du tuyau flexible haute pression. D'autre part, des moyens formant brosse de nettoyage 432 du tuyau flexible haute pression sont prévus en aval de la roue d'entrainement 43. Ces moyens formant brosse de nettoyage 432 interviennent lors de l'enroulement du tuyau flexible haute pression de sorte à en assurer un nettoyage avant que le tuyau flexible haute pression réintègre son lieu de stockage au sein du véhicule hydrocureur 1 selon l'invention. En variante de réalisation, la roue d'entrainement 43 est remplacé par un enrouleur du tuyau flexible haute pression.On the other hand, still at the level of the free end 42, the telescopic arm 4 comprises means for driving the high pressure flexible pipe. The means for driving the high pressure flexible pipe comprise, here, a driving wheel 43 for the high pressure flexible pipe implemented with the aid of a motor 430 which is here a motor of the hydraulic type, for example.

On the other hand, means forming a cleaning brush 432 of the high pressure flexible pipe are provided downstream of the drive wheel 43. These means forming a cleaning brush 432 intervene during the winding of the high pressure flexible pipe so as to ensure that it is cleaned before the high pressure flexible pipe returns to its storage location within the water cleaning vehicle 1 according to the invention. As an alternative embodiment, the drive wheel 43 is replaced by a reel of the high pressure flexible pipe.

Nous allons maintenant décrire un fonctionnement du bras articulé 10 du véhicule hydrocureur 1 selon l'invention qui vient d'être décrit précédemment en détails. En particulier, le véhicule hydrocureur 1 selon l'invention comporte des moyens de pilotage non illustrés d'au moins un reploiement automne du bras articulé 10 depuis une position déployée d'utilisation vers une position reployée faisant partie de la position de conduite du véhicule hydrocureur 1 selon l'invention. D'autre part, les moyens de pilotage peuvent piloter de manière autonome au moins une partie du déploiement du bras articulé 10 depuis sa position reployée de la position de conduite du véhicule hydrocureur 1 selon l'invention vers une position déployée d'utilisation.We will now describe an operation of the articulated arm 10 of the hydrocurner vehicle 1 according to the invention which has just been described above in detail. In particular, the water-cleaning vehicle 1 according to the invention comprises means for controlling at least one fall folding of the articulated arm 10 from a deployed position of use to a stowed position forming part of the driving position of the water-cleaning vehicle, not shown. 1 according to the invention. On the other hand, the piloting means can autonomously pilot at least part of the deployment of the articulated arm 10 from its stowed position of the driving position of the water cleaning vehicle 1 according to the invention to a deployed position of use.

Lors d'un reploiement du bras articulé 10 depuis la position déployée d'utilisation vers sa position reployée, les moyens de pilotage déclenchent une étape d'enroulement des tuyaux flexibles d'aspiration et haute pression, en activant les moteurs 364 et 430, jusqu'à ce qu'une extrémité, comportant des buses, desdits tuyaux arrive au niveau de l'extrémité libre 42 du bras articulé 10. Dès lors, les moyens de pilotage, déclenchent une étape de télescopage du bras télescopique 4 dans le bras intermédiaire 30 en provoquant un mouvement de translation du corps de bras télescopique 40 dans le corps de bras intermédiaire 30, en activant le vérin 37. Le télescopage est accompagné d'un enroulement supplémentaire des tuyaux flexibles d'aspiration et / ou haute pression, enroulement asservi alors au mouvement de télescopage, en activant de manière synchronisée les moteurs 364 et 430. Ensuite, les moyens de pilotage effectuent une rotation du bras de base 2 par rapport à la citerne de stockage 5 de sorte à ce que le corps de bras de base 20 soit parallèle à l'axe longitudinal de la citerne de stockage 5, l'avant-bras 11 dépassant vers l'arrière en saillie de l'extrémité arrière de la citerne de stockage 5. Ensuite, les moyens de pilotage effectuent un mouvement de pivotement de l'avant-bras 11 par activation des vérins 27, de sorte à ce que l'avant-bras 11 vienne en regard et en appui sur l'extrémité arrière de la citerne de stockage 5, parallèlement à cette extrémité arrière. Le bras articulé 10 est alors en position reployée de la position de conduite du véhicule hydrocureur 1 selon l'invention, cette position étant par exemple illustrée à la figure 9. Ensuite, un verrouillage éventuel de l'avant-bras 11 sur l'extrémité arrière de la citerne de stockage 5 peut être effectué.When the articulated arm 10 is folded back from the deployed position of use towards its folded position, the control means trigger a step of winding the flexible suction and high pressure pipes, in activating the motors 364 and 430, until one end, comprising nozzles, of said pipes arrives at the level of the free end 42 of the articulated arm 10. Therefore, the control means trigger a step of telescoping the telescopic arm 4 in the intermediate arm 30 by causing a translational movement of the telescopic arm body 40 in the intermediate arm body 30, activating the cylinder 37. The telescoping is accompanied by an additional winding of the flexible suction pipes and / or high pressure, winding then slaved to the telescoping movement, by synchronously activating the motors 364 and 430. Then, the control means rotate the base arm 2 with respect to the storage tank 5 so that this that the base arm body 20 is parallel to the longitudinal axis of the storage tank 5, the forearm 11 projecting rearwardly projecting from the rear end of the storage tank 5. Next, the piloting means perform a pivoting movement of the forearm 11 by activating the jacks 27, so that the forearm 11 faces and rests on the rear end of the storage tank 5, parallel to this rear end. The articulated arm 10 is then in the folded position of the driving position of the hydrocurner vehicle 1 according to the invention, this position being for example illustrated in figure 9 . Then, a possible locking of the forearm 11 on the rear end of the storage tank 5 can be performed.

Concernant le déploiement, les moyens de pilotage, dans la partie autonome de ce déploiement, effectue le déverrouillage éventuel de l'avant-bras 11 de l'extrémité arrière de la citerne de stockage 5. Puis les moyens de pilotage effectuent un mouvement de pivotement de l'avant-bras 11 par activation des vérins 27 de sorte à relever l'avant-bras 11, ce dernier quittant alors sa position en regard et en appui sur l'extrémité arrière de la citerne de stockage 5, parallèlement à celle-ci, vers une position horizontale dans le prolongement du corps de bras de base 22 du bras de base 2. Ensuite, un opérateur, de manière manuelle et à l'aide des moyens de pilotage, positionne l'extrémité libre 42 du bras articulé 10 au droit du point d'insertion choisi, en faisant faire un pivotement du bras de base 2 par rapport à la citerne de stockage 5 et un télescopage du bras télescopique 4 par rapport au bras intermédiaire 3, le pivotement et le télescopage pouvant être concomitants.Regarding the deployment, the piloting means, in the autonomous part of this deployment, perform the possible unlocking of the forearm 11 from the rear end of the storage tank 5. Then the piloting means perform a pivoting movement of the forearm 11 by activating the jacks 27 so as to raise the forearm 11, the latter then leaving its position facing and resting on the rear end of the storage tank 5, parallel to it Ci, to a horizontal position in the extension of the base arm body 22 of the base arm 2. Then, an operator, manually and using the piloting means, positions the free end 42 of the articulated arm 10 to the right of the chosen insertion point, by pivoting the base arm 2 with respect to the storage tank 5 and telescoping the telescopic arm 4 by relative to the intermediate arm 3, the pivoting and the telescoping can be concomitant.

Dans une variante de réalisation, les moyens de pilotage comprennent au moins une centrale inertielle fixée sur le bras articulé 10. L'utilisation d'une telle centrale inertielle permet de connaitre et de gérer avec précision le positionnement du bras articulée 10 lors d'un reploiement et/ou d'un déploiement de ce dernier. Par exemple, la centrale inertielle est fixée au niveau de l'extrémité libre 42 du bras télescopique 4 de l'avant-bras 11 du bras articulé 10.In an alternative embodiment, the control means comprise at least one inertial unit fixed on the articulated arm 10. The use of such an inertial unit makes it possible to know and manage with precision the positioning of the articulated arm 10 during a replication and / or deployment of the latter. For example, the inertial unit is fixed at the level of the free end 42 of the telescopic arm 4 of the forearm 11 of the articulated arm 10.

Une telle structure et agencement du bras articulé 10 au sein du véhicule hydrocureur 1 selon l'invention permet une optimisation de l'espace occupé par le bras articulé 10 en position reployée de la position de conduite du véhicule hydrocureur 1 selon l'invention. L'avant-bras 11 est alors dans un volume situé au droit de la tôle de déversement 7 du véhicule hydrocureur 1 selon l'invention. De son coté, l'enrouleur 23 du tuyau flexible d'aspiration est alors monté au plus proche de l'extrémité arrière de la citerne de stockage 5, n'occupant ainsi qu'un volume minimal au-dessus de la citerne de stockage 5.Such a structure and arrangement of the articulated arm 10 within the hydrocurger vehicle 1 according to the invention allows optimization of the space occupied by the articulated arm 10 in the stowed position of the driving position of the hydrocurger vehicle 1 according to the invention. The forearm 11 is then in a volume located at the level of the discharge plate 7 of the hydrocurner vehicle 1 according to the invention. For its part, the reel 23 of the flexible suction hose is then mounted as close as possible to the rear end of the storage tank 5, thus occupying only a minimum volume above the storage tank 5. .

Bien entendu, il est possible d'apporter à l'invention de nombreuses modifications sans pour autant sortir du cadre de celle-ci.Of course, it is possible to make numerous modifications to the invention without departing from the scope thereof.
