Description

La présente invention concerne un dispositif de guidage pour l'enroulement de flexibles hydrauliques sur un tambour, notamment, dans l'alimentation d'appareils hydrauliques de machines de forage.The present invention relates to a guiding device for the winding of hydraulic hoses on a drum, particularly in the supply of hydraulic apparatus of drilling machines.

Pour la réalisation de tranchées dans le sol en forme de parois, on connaît des outils de fraisage appelés le plus souvent fraises. Elles comportent un châssis suspendu à l'extrémité de moyens de levage, ce châssis étant muni à son extrémité inférieure de deux roues entraînées par des moteurs hydrauliques et munies de dents réparties sur deux tambours à axes horizontaux. Ces moteurs hydrauliques sont alimentés par un fluide hydraulique qui est acheminé depuis la surface par l'intermédiaire de tuyaux souples, appelés également flexibles hydrauliques. Pour alimenter les commandes hydrauliques, il est nécessaire d'acheminer, sur une longueur pouvant aller jusqu'à une centaine de mètres, un grand nombre de flexibles hydrauliques. Pour assurer à la fois le guidage de ces flexibles et l'enroulement sur le tambour situé à la surface, on utilise un dispositif de guidage des flexibles.For the production of trenches in the soil in the form of walls, milling tools known as strawberries are known. They comprise a frame suspended at the end of lifting means, this frame being provided at its lower end with two wheels driven by hydraulic motors and provided with teeth distributed on two drums with horizontal axes. These hydraulic motors are powered by a hydraulic fluid which is conveyed from the surface by means of flexible hoses, also called hydraulic hoses. To supply the hydraulic controls, it is necessary to route a large number of hydraulic hoses over a length of up to a hundred meters. To ensure both the guiding of these hoses and the winding on the drum located on the surface, a hose guiding device is used.

Un tel guide pour tuyaux souples est décrit dans le document EP 518 292 qui correspond au préambule de la revendication 1. Le dispositif de guidage décrit dans ce brevet comporte des pièces transversales espacées longitudinalement sur toute la longueur du guide, servant à recevoir des tuyaux souples orientés perpendiculairement aux pièces transversales. Ces pièces transversales reposent à chacune de leurs extrémités sur une entretoise de maintien. Sur les bords du guide sont prévues des pièces d'extrémités ayant la même forme que les entretoises de maintien. La liaison des entretoises de maintien et des pièces d'extrémités est obtenue grâce à deux câbles de traction sur lesquels ces pièces sont enfilées. La liaison articulée est obtenue par le fait qu'il est prévu que les entretoises de maintien et les pièces d'extrémités comportent des formes profilées de guidage sur les deux faces opposées. Lors de l'enroulement sur le tambour, les entretoises de maintien se placent par couches directement les unes au-dessus des autres.Such a guide for flexible hoses is described in the document EP 518 292 which corresponds to the preamble of claim 1. The guide device described in this patent comprises transverse pieces spaced longitudinally along the entire length of the guide, for receiving flexible pipes oriented perpendicular to the cross pieces. These transverse pieces rest at each of their ends on a holding spacer. On the edges of the guide are end pieces having the same shape as the holding struts. The connection of the holding struts and the end pieces is obtained by means of two traction cables on which these parts are threaded. The articulated connection is obtained in that it is expected that the holding struts and the end pieces have profiled guide shapes on the two opposite faces. During winding on the drum, the holding struts are placed in layers directly above one another.

Ce type de guidage pour flexibles hydrauliques présente deux inconvénients majeurs. Tout d'abord, la réalisation des entretoises de maintien et des pièces de bords demande l'agencement précis de nombreuses pièces dont les faces doivent être correctement usinées pour créer la liaison articulée. La fabrication d'un tel dispositif est donc complexe et relativement coûteuse. Par ailleurs, lorsque le guide est enroulé sur le tambour, le diamètre de l'enroulement est très important à cause de la hauteur des entretoises de maintien qui sont empilées les unes sur les autres. Les pièces d'extrémités et les entretoises de maintien augmentent également la masse linéaire du dispositif de guidage si bien que la masse globale du dispositif ainsi que son encombrement, obligera à utiliser des tambours aux dimensions importantes.This type of guidance for hydraulic hoses has two major disadvantages. First of all, the realization of the holding struts and the edge pieces requires the precise arrangement of many parts whose faces must be properly machined to create the articulated connection. The manufacture of such a device is therefore complex and relatively expensive. By the way, when the guide is wound on the drum, the diameter of the winding is very important because of the height of the holding struts which are stacked on each other. The end pieces and the holding struts also increase the linear mass of the guiding device so that the overall mass of the device and its bulk, will require the use of large drums.

En outre, les câbles de traction situés sur les deux côtés du dispositif de guidage servent uniquement à maintenir une tension constante dans le guide et ne servent pas à porter le châssis. En effet, celui-ci est suspendu par le biais du câble de traction 14.In addition, the traction cables located on both sides of the guiding device serve only to maintain a constant tension in the guide and are not used to carry the frame. Indeed, it is suspended by means of the traction cable 14.

La présente invention a pour but de proposer un dispositif de guidage pour l'enroulement de tuyaux flexibles sur un tambour, qui soit de fabrication simple, compacte et peu coûteuse, apte à surmonter les inconvénients mentionnés ci-dessus, en particulier pour ce qui concerne le problème de l'enroulement.The present invention aims to provide a guide device for winding flexible hoses on a drum, which is simple, compact and inexpensive to manufacture, able to overcome the drawbacks mentioned above, in particular with regard to the problem of winding.

Ce but est atteint grâce au fait que le dispositif de guidage comprend des pièces transversales espacées périodiquement sur la longueur du dispositif de guidage, destinées à recevoir au moins deux flexibles hydrauliques orientés perpendiculairement par rapport aux pièces transversales, ledit dispositif se caractérisant en ce qu'il comporte au moins un flexible porteur ayant sensiblement le même diamètre que lesdits flexibles hydrauliques, et en ce que ledit au moins un flexible porteur comporte au moins un câble porteur entouré d'un moyen d'enrobage, et présente un moyen de fixation en ses extrémités.This object is achieved thanks to the fact that the guiding device comprises transverse pieces spaced periodically along the length of the guiding device, intended to receive at least two hydraulic hoses oriented perpendicular to the transverse parts, said device being characterized in that it comprises at least one carrier hose having substantially the same diameter as said hydraulic hoses, and in that said at least one carrier hose comprises at least one carrier cable surrounded by a coating means, and has a fixing means in its ends.

On comprend que le dispositif de guidage est d'une configuration telle qu'il n'est pas nécessaire de disposer ni de pièces d'extrémités, ni d'entretoises de maintien. Il y a donc moins de pièces à fabriquer et à assembler.It is understood that the guide device is of such a configuration that it is not necessary to have either end pieces or holding struts. There are fewer parts to manufacture and assemble.

En outre, les flexibles hydrauliques et porteurs ont le même diamètre, ainsi, lors de l'enroulement sur le tambour, deux couches de flexibles trouvent appui l'une par rapport à l'autre, au niveau de chacun des flexibles et surtout sans risque d'écrasement.In addition, the hydraulic hoses and carriers have the same diameter, thus, during the winding on the drum, two layers of hoses find support relative to each other, at each of the hoses and especially without risk crushing.

Il est également intéressant de noter que dans la présente invention, il est possible de n'utiliser qu'un seul flexible porteur alors que deux sont nécessaires dans le document EP 518 292 . En particulier, ceux-ci sont obligatoirement situés aux extrémités car ils assurent la fixation des entretoises de maintien et des pièces d'extrémités. Dans la présente invention, il est possible d'imaginer plusieurs configurations de placement de flexibles porteurs.It is also interesting to note that in the present invention it is possible to use only one carrier hose while two are required in the document EP 518 292 . In particular, these are necessarily located at the ends because they ensure the fixing of holding struts and end pieces. In the present invention, it is possible to imagine several configurations of flexible carrier placement.

Avantageusement, au moins certaines des pièces transversales comportent des moyens de solidarisation avec les moyens de fixation du flexible porteur. En particulier, les blocs de jonction sont les pièces transversales situées aux extrémités du dispositif de guidage. Les extrémités des flexibles porteurs sont munies d'un appendice de fixation venant s'emboîter dans une zone de la pièce transversale. Une pièce en forme de mâchoire est ensuite vissée au bloc pour assurer la solidarisation de l'appendice de fixation du flexible porteur avec le bloc de jonction.Advantageously, at least some of the transverse parts comprise securing means with the fastening means of the carrier hose. In particular, the terminal blocks are the transverse pieces located at the ends of the guide device. The ends of the carrier hoses are provided with an attachment appendix fitting into an area of the crosspiece. A jaw-shaped piece is then screwed to the block to secure the fastening appendage of the carrier hose with the terminal block.

Avantageusement, le flexible porteur est composé d'une pluralité de portions de flexibles porteurs.Advantageously, the carrier hose is composed of a plurality of carrier flexible portions.

Chaque portion de flexible porteur est solidarisée soit à un bloc de jonction si la portion de flexible porteur se trouve à l'une des extrémités du dispositif de guidage, soit à une pièce transversale de reprise d'effort comportant des moyens de solidarisation. Ces pièces de reprise d'effort sont composées en deux flexibles comportant des passages pour les flexibles et des mâchoires pour la solidarisation des moyens de fixation des portions de flexibles porteurs.Each portion of carrier hose is secured to either a junction block if the carrier hose portion is at one end of the guide device, or to a transverse piece of force recovery having securing means. These force recovery parts are composed of two hoses with passages for the hoses and jaws for securing the means for fixing the portions of flexible hoses.

L'avantage d'une telle configuration apparaît, par exemple, lors d'une rupture d'un flexible porteur. Dans la présente invention, il suffit simplement de changer la portion de porteur endommagée, tandis que dans le dispositif du document EP 518 292 , il faut déposer l'ensemble des pièces d'extrémités et entretoises de maintien ainsi que le brin de câble ayant cassé, et ensuite remonter l'ensemble. Dans cette hypothèse, il est évident que le temps perdu lors de la réparation est un inconvénient majeur.The advantage of such a configuration appears, for example, during a rupture of a carrier hose. In the present invention, it suffices to simply change the damaged carrier portion, while in the document device EP 518 292 it is necessary to deposit all the end pieces and holding spacers as well as the cable strand having broken, and then reassemble the assembly. In this hypothesis, it is obvious that the time lost during the repair is a major disadvantage.

L'invention sera mieux comprise et ses avantages apparaîtront mieux à la lecture de la description détaillée qui suit, de modes de réalisation représentés à titre d'exemples non limitatifs. La description se réfère aux dessins, sur lesquels :

  • La figure 1 est une vue en perspective d'un outillage pour parois moulées à grande profondeur ;
  • La figure 2 est une vue en perspective d'une partie du dispositif de guidage ;
  • La figure 3 est une vue de côté partielle du dispositif de guidage ;
  • La figure 4 est une vue en coupe longitudinale du moyen de fixation du flexible porteur sur un bloc de jonction ;
  • La figure 5 est une vue de dessus du dispositif de guidage comportant deux flexibles porteurs.
The invention will be better understood and its advantages will appear better on reading the detailed description which follows, of embodiments shown by way of non-limiting examples. The description refers to the drawings, in which:
  • The figure 1 is a perspective view of deep-walled mold tooling;
  • The Figure 2 is a perspective view of a portion of the guide device;
  • The figure 3 is a partial side view of the guide device;
  • The figure 4 is a longitudinal sectional view of the fixing means of the carrier hose on a terminal block;
  • The figure 5 is a top view of the guide device comprising two flexible carriers.

L'outillage pour la réalisation de parois moulées de grande profondeur représenté sur la figure 1 comprend un véhicule à chenilles 10 équipé d'une potence 12 sur laquelle est suspendu un châssis de fraisage 14. Deux paires de roues de fraisage 16 d'axes horizontaux entraînées par des moteurs hydrauliques sont disposées à l'extrémité inférieure du châssis de fraisage 14. Ces roues de fraisage sont équipées de dents réparties en périphérie et destinées à creuser le sol.The tooling for the realization of very deep diaphragm walls represented on the figure 1 comprises a tracked vehicle 10 equipped with a bracket 12 on which is suspended a milling frame 14. Two pairs of horizontal axis milling wheels 16 driven by hydraulic motors are arranged at the lower end of the milling frame 14 . These milling wheels have teeth distributed peripherally and for digging.

Une pompe hydraulique 18 est également installée sur cette partie du châssis 14, au dessus des roues de fraisage. Cette pompe permet d'aspirer les particules découpées par les fraises et de les évacuer vers la surface par l'intermédiaire du tuyau d'évacuation 20. A hydraulic pump 18 is also installed on this part of the frame 14, above the milling wheels. This pump makes it possible to suck the particles cut by the cutters and to evacuate them to the surface via the discharge pipe 20.

Le fonctionnement des différents organes hydrauliques (les moteurs, la pompe et éventuellement d'autres composants hydrauliques) nécessite une alimentation en fluide. Cette alimentation est réalisée par l'intermédiaire de flexibles hydrauliques 22 qui acheminent le fluide depuis la surface jusqu'aux différents appareils hydrauliques. En pratique, ces flexibles hydrauliques 22 ont sensiblement la même forme géométrique et les mêmes dimensions, donc, en particulier, le même diamètre. Les flexibles sont enroulés, en amont, sur un tambour 13 fixé au véhicule 10. The operation of the various hydraulic components (the motors, the pump and possibly other hydraulic components) requires a fluid supply. This supply is achieved by means of hydraulic hoses 22 which convey the fluid from the surface to the various hydraulic devices. In practice, these hydraulic hoses 22 have substantially the same geometric shape and the same dimensions, therefore, in particular, the same diameter. The hoses are wound upstream on a drum 13 attached to the vehicle 10.

Les flexibles hydrauliques sont regroupés et maintenus ensembles sur un support de guidage 24 comme le montre la figure 2 . Dans cette représentation, il s'agit d'un dispositif de guidage pour huit flexibles hydrauliques 22. Dans ce dispositif de guidage, les flexibles hydrauliques 22 sont maintenus alignés parallèlement et avec un écartement sensiblement identique entre deux flexibles adjacents.The hydraulic hoses are grouped and held together on a guide support 24 as shown in FIG. figure 2 . In this representation, there is a guide device for eight hydraulic hoses 22. In this guiding device, the hydraulic hoses 22 are held aligned parallel and with a substantially identical spacing between two adjacent hoses.

En outre, ce dispositif de guidage 24 comporte un flexible porteur 26 servant, d'une part, à maintenir une tension constante dans le dispositif de guidage 24 et, d'autre part, à porter le châssis de fraisage 14. Une particularité importante de ce flexible porteur 26 est qu'il a sensiblement la même forme et les mêmes dimensions que les flexibles hydrauliques 22. Sur l'exemple représenté sur la figure 2 , le flexible porteur 26 a sensiblement la même forme cylindrique et le même diamètre que les flexibles hydrauliques 22.In addition, this guiding device 24 comprises a carrier hose 26 serving, on the one hand, to maintain a constant tension in the guide device 24 and, on the other hand, to carry the milling frame 14. An important feature of this carrier hose 26 is that it has substantially the same shape and dimensions as the hydraulic hoses 22. In the example shown in FIG. Figure 2 , the flexible carrier 26 has substantially the same cylindrical shape and the same diameter as the hydraulic hoses 22 .

A chaque extrémité du dispositif de guidage 24 est prévu un bloc de jonction 28 qui est un élément transversal auquel sont fixés les flexibles hydrauliques 22 et le flexible porteur 26. Les blocs de jonction 28 permettent de raccorder les flexibles hydrauliques 22 en amont à la source de fluide et en aval aux moteurs et à la pompe hydraulique 18 (non représentés ici). Ils peuvent également permettre de raccorder deux dispositifs de guidage entre eux, en particulier lorsqu'il est nécessaire de creuser à une profondeur importante. En pratique, il est prévu un bloc de jonction 28 chaque trente mètres de flexibles hydrauliques 22.At each end of the guiding device 24 is provided a junction block 28 which is a transverse element to which the hydraulic hoses 22 and the carrier hose 26 are fixed. The terminal blocks 28 make it possible to connect the hydraulic hoses 22 upstream to the source of fluid and downstream to the motors and to the hydraulic pump 18 (not shown here). They can also make it possible to connect two guiding devices between them, in particular when it is necessary to dig to a large depth. In practice, there is a terminal block 28 each thirty meters of hydraulic hose 22.

Le bloc de jonction 28 est donc une pièce de forme sensiblement rectangulaire comportant des trous cylindriques 30 parallèles et équidistants le traversant de part en part. Les extrémités des flexibles hydrauliques 22 viennent s'emmancher d'une manière étanche dans ces trous 30.The junction block 28 is therefore a substantially rectangular piece having parallel and equidistant cylindrical holes 30 passing through it from one side to the other. The ends of the hydraulic hoses 22 are leaktight in these holes 30 .

Le flexible porteur 26 est fixé également sur le bloc de jonction 28. Selon la figure 3 , ce flexible comprend en son extrémité un moyen de fixation se présentant sous la forme d'un embout cylindrique 32 comportant sur sa face externe une nervure 34. The carrier hose 26 is also fixed on the terminal block 28. According to the figure 3 , this hose comprises at its end a fastening means in the form of a cylindrical tip 32 having on its outer face a rib 34.

Les embouts cylindriques 32 des flexibles porteurs 26 sont solidarisés au bloc de fixation 28 grâce à deux pièces allongées 36, 37 vissées sur le bloc de jonction 28 comportant des évidements demi-cylindriques et ayant la forme d'une mâchoire 38. L'extrémité de la mâchoire 38 s'emboîte par coopération de forme dans la nervure 34 de l'embout cylindrique 32. Les deux pièces allongées 36, 37 sont assemblées de telle sorte que les évidements demi-cylindriques des deux pièces soient en vis-à-vis. L'ensemble ainsi formé a une longueur et une largeur sensiblement égales à celles du bloc de jonction 28. Ces pièces allongées 36, 37 assurent également la solidarisation des flexibles hydrauliques 22.The cylindrical ends 32 of the flexible hoses 26 are secured to the fixing block 28 by two elongated pieces 36, 37 screwed onto the junction block 28 having half-cylindrical recesses and having the shape of a jaw 38. The end of the jaw 38 fits in a form-in the rib 34 of the cylindrical tip 32. the two elongated members 36, 37 are assembled such that the semi-cylindrical recesses of the two parts are in vis-à-vis. The assembly thus formed has a length and a width substantially equal to those of the terminal block 28. These elongated parts 36, 37 also secure the hydraulic hoses 22 .

D'après le mode de réalisation représenté sur la figure 2 , le flexible porteur 26 est composé de plusieurs portions de flexibles porteurs 26a, 26b. En pratique, la longueur d'une portion de flexible porteur 26a, 26b est d'environ six mètres.According to the embodiment shown on the figure 2 , the carrier hose 26 is composed of several portions of flexible carriers 26a, 26b . In practice, the length of a portion of carrier hose 26a, 26b is about six meters.

Les portions de flexibles porteurs 26a, 26b sont solidarisées entre elles grâce à des éléments de reprise d'effort 40 qui sont des pièces transversales comportant des moyens pour solidariser les moyens de fixation des flexibles porteurs. La figure 2 et la figure 3 montrent un tel élément de reprise d'effort 40. Il est composé de deux parties 40a, 40b vissées entre elles. Chaque partie est une pièce allongée comportant des évidements demi-cylindriques pour le passage des flexibles hydrauliques 22 ainsi qu'un évidement destiné à fixer, par coopération de forme, deux embouts de fixations 32 de deux portions adjacentes de flexibles porteurs 26a, 26b. The portions of flexible carriers 26a, 26b are secured to each other by means of force-absorbing elements 40 which are transverse parts comprising means for securing the fastening means of the carrier hoses. The Figure 2 and the figure 3 show such a force-absorbing element 40. It is composed of two parts 40a, 40b screwed together. Each part is an elongated piece having semi-cylindrical recesses for the passage of the hydraulic hoses 22 and a recess for securing, by shape cooperation, two fastener tips 32 of two adjacent portions of flexible carriers 26a, 26b.

Afin de maintenir un écartement constant entre les flexibles, on place longitudinalement des barrettes d'écartement 42 sur les flexibles. Dans la pratique, on place une barrette d'écartement chaque mètre cinquante.In order to maintain a constant spacing between the hoses, spacer bars 42 are placed longitudinally on the hoses. In practice, a spacer bar is placed every 50 meters.

Les figures 3 et 4 représentent d'une façon plus détaillée la structure d'un flexible porteur 26. Celui-ci comporte en son centre un câble porteur 44 métallique servant à supporter les efforts de traction apparaissant au sein du dispositif de guidage.The figures 3 and 4 show in more detail the structure of a carrier hose 26. The latter comprises at its center a metal carrying cable 44 for supporting the traction forces occurring within the guiding device.

Le câble porteur 44 est solidaire de l'embout de fixation 32 constituant le moyen de fixation du flexible porteur 26. Plus précisément, l'extrémité du câble porteur 44 est solidaire d'un manchon 46 qui est lui-même vissé sur l'embout de fixation 32. The carrying cable 44 is secured to the securing piece 32 constituting the fastening means of the flexible carrier 26. Specifically, the end of the support cable 44 is secured to a sleeve 46 which itself is screwed onto the end piece 32.

Ce câble porteur 26 est entouré d'un moyen d'enrobage constitué de tuyaux d'entretoises 48 de matière plastique et d'une gaine extérieure souple 50 ayant même diamètre que les flexibles hydrauliques 22. En particulier, cet enrobage permet au câble de rester centré dans le flexible porteur.This carrying cable 26 is surrounded by a coating means consisting of spacers pipes 48 of plastic material and a flexible outer sheath 50 having the same diameter as the hydraulic hoses 22. In particular, this coating allows the cable to remain centered in the carrier hose.

Cette gaine extérieure 50 est également solidaire de l'embout de fixation 32. Celui-ci comprend deux pièces cylindriques concentriques 52, 53 entre lesquelles est emmanchée en force l'extrémité de la gaine 50. This outer sheath 50 is also secured to the attachment end 32. This comprises two concentric cylindrical pieces 52, 53 between which the end of the sheath 50 is force-fitted .

De préférence, la gaine extérieure 50 est continue au moins entre deux éléments de reprise d'effort 40. Preferably, the outer sheath 50 is continuous at least between two absorbing elements 40 effort.

La figure 5 représente un autre mode de réalisation où le dispositif de guidage 24 comprend deux flexibles porteurs 26 et neuf flexibles hydrauliques 22. L'intérêt de deux flexibles porteurs réside dans le fait que la capacité de traction du dispositif est doublée et d'autre part on évite les effets de voilage pouvant se traduire par une rotation du dispositif autour d'un seul flexible central.The Figure 5 represents another embodiment where the guiding device 24 comprises two flexible hoses 26 and nine hydraulic hoses 22. The advantage of two hoses carriers lies in the fact that the tensile capacity of the device is doubled and secondly avoids the effects of warping that can result in a rotation of the device around a single central hose.

Un autre mode de réalisation consiste à ce que le flexible porteur 26 ne soit composé que d'une seule pièce. Il peut être en effet intéressant, dans certains cas, que le flexible porteur ne soit pas composé d'une pluralité de portions de flexibles porteurs.Another embodiment is that the carrier hose 26 is composed of only one piece. It may indeed be interesting, in some cases, that the carrier hose is not composed of a plurality of carrier flexible portions.

Dans un autre mode de réalisation, le flexible porteur 26 comprend une pluralité de câbles porteurs 44. Dans le cas où, par exemple, le flexible porteur comporte trois câbles porteurs 44 dont la somme des sections équivaut à la section d'un câble unique, la capacité de traction est sensiblement identique. En sus, on augmente la flexibilité du flexible porteur 26. In another embodiment, the flexible carrier 26 includes a plurality of support cables 44. In the case where, for example, the holder comprises three flexible supporting cables 44, the sum of the sections equal to the section of a single cable, the traction capacity is substantially identical. In addition, the flexibility of the carrier hose 26 is increased.

Un autre avantage réside dans le fait que si un des câbles casse, les câbles restant peuvent reprendre les efforts de traction au moins temporairement.Another advantage lies in the fact that if one of the cables breaks, the remaining cables can resume traction efforts at least temporarily.

L'avantage d'avoir des flexibles de même diamètre permet un enroulement régulier et homogène des flexibles sur le tambour de stockage 13, sans risque d'écrasement des flexibles hydrauliques 22.The advantage of having hoses of the same diameter allows a uniform and uniform winding of the hoses on the storage drum 13, without the risk of crushing the hydraulic hoses 22 .

D'autre part, la hauteur maximale du dispositif de guidage 24 est sensiblement égale au diamètre d'un flexible, si bien qu'en position enroulée, les flexibles ont une structure très compacte. Inversement, il est possible de stocker une plus grande longueur de flexible sur un tambour 13 que dans le cas connu où la hauteur du dispositif de guidage 24 est relativement importante (présence de pièces d'extrémités par exemple). En outre, la relative simplicité du dispositif assure à l'utilisateur une facilité d'utilisation et de maintenance.On the other hand, the maximum height of the guiding device 24 is substantially equal to the diameter of a hose, so that in the wound position, the hoses have a very compact structure. Conversely, it is possible to store a larger length of hose on a drum 13 than in the known case where the height of the guide device 24 is relatively large (presence of end pieces for example). In addition, the relative simplicity of the device provides the user with ease of use and maintenance.
