Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne un ensemble de stockage et de distribution de produits fluides, tels que des produits liquides, visqueux ou granuleux, du type comprenant en premier lieu des moyens de stockage desdits produits fluides présentant une ouverture inférieure de sortie, tels qu'une benne de stockage de béton à tuyau, en deuxième lieu des moyens de commande et d'interruption de distribution de tels produits fluides, disposés au-dessous de ladite ouverture inférieure de sortie, en troisième lieu des moyens de distribution associés auxdits moyens de commande et d'interruption de distribution desdits produits fluides, tels qu'une enveloppe anti-souillures, et enfin, en quatrième lieu, des moyens de fourniture d'énergie, constitués notamment d'un moteur électrique, et reliés à des moyens de déplacement qui, commandés par radiocommande, agissent sur lesdits moyens de commande et d'interruption de distribution pour les faire passer d'une position de distribution à une position d'interruption d'écoulement et inversement, lesdits moyens de déplacement comprenant un vérin à vis présentant un élément de sortie, agissant sur lesdits moyens de commande et d'interruption de distribution, et un élément d'entrée solidaire desdits moyens de fourniture d'énergie.The present invention relates to a set for storing and dispensing fluid products, such as liquid, viscous or granular products, of the type comprising in the first place storage means of said fluid products having a lower outlet opening, such as a bucket secondly, means for controlling and interrupting dispensing of such fluid products, arranged below said lower outlet opening; thirdly, dispensing means associated with said control means and interruption of distribution of said fluid products, such as an anti-fouling envelope, and finally, fourthly, energy supply means, consisting in particular of an electric motor, and connected to displacement means which, ordered by radio control, act on said distribution control and interruption means to move them from a distribution position to a flow interruption position and vice versa, said displacement means comprising a screw jack having an output member, acting on said distribution control and interruption means, and an input member integral with said supply means energy.

Bien évidemment, la présente invention a également pour objet une benne de stockage de béton à tuyau comportant des moyens de commande et d'interruption de distribution des produits fluides contenus dans la cuve de ladite benne ainsi que des moyens de distribution de ces produits fluides, telle une enveloppe anti-souillures.Of course, the subject of the present invention is also a concrete pipe storage bin comprising means for controlling and interrupting dispensing of the fluid products contained in the tank of said bucket as well as dispensing means for these fluid products, such an anti-stain envelope.

ARRIÈRE-PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

La fonction d'une benne, après qu'elle est remplie de la quantité nécessaire de béton, est d'assurer spécifiquement le transport et la mise en place de sa masse de béton en un point du chantier parfaitement défini.The function of a bucket, after it is filled with the necessary amount of concrete, is to specifically ensure the transport and placement of its mass of concrete at a perfectly defined site.

Tant l'opération de transport que l'opération de coulage du béton à l'emplacement désiré sont réputées être dangereuses.Both the transport operation and the concrete pouring operation at the desired location are deemed to be hazardous.

Afin de ne jamais utiliser une benne dans des conditions non compatibles avec les règles de sécurité, il a donc été imaginé dès les années 1970 de doter les moyens d'ouverture et de fermeture de la trappe par laquelle le béton aura à être déversé d'un dispositif commandé par radiocommande, et en outre il a été proposé d'associer ce dispositif radiocommandé à un actionneur hydraulique ou à un actionneur pneumatique.In order to never use a bucket in conditions that are not compatible with the safety rules, it was therefore devised in the 1970s to provide the means of opening and closing the trap through which the concrete will have to be dumped. a device controlled by radio control, and further it has been proposed to associate this radio-controlled device with a hydraulic actuator or a pneumatic actuator.

Les uns et les autres de ces actionneurs présentent toutefois de nombreux inconvénients.Both of these actuators, however, have many disadvantages.

Ainsi, si les vérins hydrauliques ont l'avantage de la robustesse et de la fiabilité de leurs composants, ainsi que la précision et la puissance de leurs mouvements, ils ont l'inconvénient d'être d'un rendement et d'une autonomie faibles, d'être lents à recharger, et surtout ils ont l'inconvénient d'être constitués de composants volumineux - en particulier le groupe hydraulique - ce qui implique que leurs composants soient pour une infime partie fixés sur la trappe à manoeuvrer et, pour leur autre partie, la plus importante, fixés sur la cuve de la benne.Thus, if the hydraulic cylinders have the advantage of the robustness and reliability of their components, as well as the accuracy and power of their movements, they have the disadvantage of being of low efficiency and autonomy , to be slow to recharge, and especially they have the disadvantage of being composed of bulky components - in particular the hydraulic unit - which implies that their components are for a tiny part fixed on the door to maneuver and, for their other part, the most important, fixed on the tank of the bucket.

Il en est notamment ainsi du groupe hydraulique dont le volume est tel qu'il ne saurait être fixé sur la trappe à manoeuvrer.This is particularly the hydraulic group whose volume is such that it can not be fixed on the hatch to maneuver.

Dans le même esprit, si les vérins pneumatiques ont l'avantage d'une grande souplesse dans leurs mouvements et de pouvoir être rechargés rapidement, en quelques minutes, ils présentent des inconvénients similaires à ceux des vérins hydrauliques, à savoir que leur réservoir est très volumineux, bien que n'assurant qu'une faible autonomie, et qu'en conséquence seulement quelques rares composants de ces vérins pneumatiques peuvent être fixés sur la trappe à manoeuvrer, l'essentiel de leurs composants, et en particulier les réservoirs d'air, étant si volumineux qu'il y a obligation de les fixer sur la cuve de la benne.In the same spirit, if the pneumatic cylinders have the advantage of a great flexibility in their movements and can be recharged quickly, in a few minutes, they have disadvantages similar to those of hydraulic cylinders, namely that their reservoir is very bulky, although with little autonomy, and that Consequently, only a few components of these pneumatic cylinders can be fixed to the hatch to be operated, the bulk of their components, and in particular the air tanks, being so large that it is necessary to fix them on the tank. the bucket.

Autrement dit, les bennes équipées pour l'ouverture et la fermeture de leur trappe d'un vérin hydraulique, ou d'un vérin pneumatique, sont fabriquées spécifiquement pour ces fonctions hydraulique ou pneumatique.In other words, the buckets equipped for the opening and closing of their hatch of a hydraulic cylinder, or a pneumatic cylinder, are manufactured specifically for these hydraulic or pneumatic functions.

Et, en cas de panne, il n'y a donc d'autre solution pour remplacer des vérins endommagés que celle de les démonter, c'est-à-dire de les retirer de la cuve de la benne avec leurs supports, ce qui constitue des opérations très lourdes en temps, en minutie et en matière de coût.And, in case of failure, there is therefore no alternative to replace damaged cylinders that the one to disassemble them, that is to say to remove them from the tank of the bucket with their supports, which is very time-consuming, meticulous and cost-intensive.

Nonobstant ces défauts, il n'a jusqu'ici jamais été envisagé, du moins sur chantiers, de remplacer les vérins hydrauliques et les vérins pneumatiques par des vérins tout électriques, ces derniers ayant la réputation d'être d'une vitesse très lente et se révélant être d'une très grande fragilité au regard des agressions inhérentes à tous les chantiers à ciel ouvert. Par ailleurs, comme il ne saurait être question que des câbles électriques puissent être dispersés sur un chantier pour alimenter des vérins tout électriques, ceux-ci n'ont été jusqu'à aujourd'hui que montés sur des bennes associées à des ponts roulants, dotés de leurs propres moyens de fourniture d'énergie, mais jamais ils n'ont été montés sur des bennes autonomes, c'est-à-dire sur des bennes dont le transport est assuré par des grues. La demande de brevet DE 23 65 140 publiée le 6 mars 1975 illustre ainsi l'emploi sur une benne utilisée dans une usine de préfabrication, ou dans un atelier couvert, d'un vérin à vis sans fin dont la rotation est commandée par un moteur électrique. C'est alors via le crochet du pont roulant qui porte une telle benne en milieu couvert que le vérin électrique peut être alimenté en courant. En revanche, sur un chantier à ciel ouvert, il ne saurait être question d'alimenter en courant un vérin électrique via le crochet de la grue qui transporte une benne autonome.Notwithstanding these defects, it has hitherto never been envisaged, at least on construction sites, to replace the hydraulic cylinders and the pneumatic cylinders with all-electric cylinders, the latter having the reputation of being of a very slow speed and proving to be very fragile in view of the aggressions inherent in all open pit sites. Moreover, since there can be no question that electrical cables can be dispersed on a construction site to power all-electric cylinders, they have been until now only mounted on skips associated with cranes, with their own means of energy supply, but they have never been mounted on autonomous skips, that is to say on skips whose transport is provided by cranes. The patent application DE 23 65 140 published on March 6, 1975 illustrates the use on a bucket used in a prefabrication plant, or in a covered workshop, a worm cylinder whose rotation is controlled by an electric motor. It is then via the crane hook that carries such a bucket in the covered environment that the electric cylinder can be powered. On the other hand, on an open-air construction site, there can be no question to supply current to an electric jack via the hook of the crane which carries an autonomous bucket.

Il est par ailleurs connu de fixer sous la cuve d'une benne à béton, au moyen de brides qui se correspondent, un dispositif de vidage comprenant notamment une trappe d'obturation de l'ouverture inférieure de la cuve, ledit dispositif de vidage étant au surplus associé à une enveloppe anti-souillures de forme conique ou de forme tronc-pyramidale, une telle enveloppe ayant pour rôle de maintenir la continuité de la veine de béton qui s'écoule et donc d'éviter que ne se produisent des débordements et des projections extérieures de béton.It is also known to fix under the tank of a concrete container, by means of corresponding flanges, a dump device comprising in particular a shutter of the lower opening of the vessel, said dump device being in addition, associated with a conical-shaped or truncated-pyramidal anti-contamination envelope, such an envelope having the role of maintaining the continuity of the pouring concrete stream and thus avoiding overflowing and external projections of concrete.

Le brevet européen publié le 25 août 2004 sous le n° 1.449.984 décrit un tel dispositif de vidage et ses avantages nombreux parmi lesquels, en particulier, celui de pouvoir séparer aisément ledit dispositif de vidage relativement à la base de la cuve et de pouvoir ainsi changer tout aussi aisément un mécanisme défectueux d'ouverture/fermeture de la trappe sans avoir à intervenir sur la cuve de la benne.The European patent published on August 25, 2004 under number 1449984 describes such a dump device and its numerous advantages among which, in particular, that of being able to easily separate said dump device relative to the base of the tank and thus be able to change just as easily a defective opening / closing mechanism of the hatch without having to intervene on the tank of the bucket.

Il a été proposé quelques constructions de bennes reproduisant l'enseignement du brevet européen précité et d'associer leurs mécanismes d'ouverture/fermeture de trappe à des vérins hydrauliques ou pneumatiques mais, compte tenu des volumes nécessaires pour la pose des réservoirs de tels vérins, ces bennes n'ont jamais pu être standardisées. Ainsi, leur fabrication n'est le fait que de commandes spéciales, alors pourtant que l'on connaît les avantages que procurent les dispositifs de vidage objets du brevet européen n° 1.449.984 .It has been proposed some constructions of skips reproducing the teaching of the aforementioned European patent and to associate their mechanisms of opening / closing trap door to hydraulic or pneumatic cylinders but, taking into account the volumes necessary for the installation of the tanks of such cylinders these skips have never been standardized. Thus, their manufacture is only the fact of special orders, so that we know the advantages that provide dump devices subject to European Patent No. 1449984 .

La présente invention propose de combiner les avantages de certains des matériels décrits ci-dessus et de donner plus particulièrement une solution standardisée de montage d'un vérin électrique sur un dispositif de vidage correspondant au brevet européen précité, dont le démontage en vue de son nettoyage ou de son remplacement est aisé.The present invention proposes to combine the advantages of some of the materials described above and more particularly to provide a standardized solution for mounting an electric jack on a dump device corresponding to the aforementioned European patent, including disassembly for cleaning or its replacement is easy.

La construction préconisée selon DE 23 65 140 ne peut donner satisfaction de ce point de vue, le vérin à vis et le moteur qui commande la rotation dudit vérin étant montés entre la partie supérieure de la cuve de la benne et les moyens de commande et d'interruption de distribution des produits fluides, comme il a par ailleurs été proposé jusqu'à aujourd'hui dans toutes les constructions utilisant des vérins, soit pneumatiques, soit hydrauliques.The recommended construction according to DE 23 65 140 can not be satisfactory from this point of view, the screw jack and the engine which controls the rotation of said cylinder being mounted between the upper part of the bucket of the bucket and the control means and interruption of distribution of fluid products, as it has been proposed until today in all constructions using cylinders, either pneumatic or hydraulic.

DESCRIPTION DES MODES DE RÉALISATION PRÉFÉRÉS DE L'INVENTIONDESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Il a été représenté aux figures 1 à 4, les trois constituants essentiels d'un ensemble conforme à l'invention, ces trois éléments étant provisoirement séparés.He was represented at Figures 1 to 4 , the three essential components of an assembly according to the invention, these three elements being provisionally separated.

La benne 1 est de type couchée, c'est-à-dire que la cuve 2 de forme générale tronpyramidale est montée sur un piétement en forme de berceau constitué de barres métalliques, à savoir successivement deux barres parallèles 3 qui sont soudées à l'arrière de la cuve 2 et qui sont courbées vers le haut à leur partie avant et de deux barres avant 4 qui assurent chacune la liaison entre un renfort 5 de la partie avant de la cuve 2 et l'extrémité haute de chaque barre 3.The bucket 1 is of the recumbent type, that is to say that the tank 2 of generally tronpyramidal shape is mounted on a cradle-shaped base consisting of metal bars, namely successively two parallel bars 3 which are welded to the rear of the tank 2 and which are curved upwards at their front part and two front bars 4 which each provide the connection between a reinforcement 5 of the front part of the tank 2 and the upper end of each bar 3.

Des raidisseurs tubulaires 6 ou en forme de plaque 7 relient avantageusement les deux barres latérales 3.Tubular or plate-shaped stiffeners 7 advantageously connect the two lateral bars 3.

A sa partie basse, la cuve 2 de la benne 1 présente une ouverture 8 de sortie des produits fluides, en l'occurrence du béton, stockés dans ladite cuve.At its lower part, the tank 2 of the bucket 1 has an outlet opening 8 for fluid products, in this case concrete, stored in said tank.

La benne 1 pourrait tout aussi bien être de type droite, et dans ce cas la cuve de cette benne droite sera, de façon classique, soudée sur les quatre pieds d'un piétement.The bucket 1 could equally well be of the right type, and in this case the tank of this right dump will be, in a conventional manner, welded to the four legs of a base.

Le deuxième élément est un dispositif de guidage 9 composé essentiellement d'une manchette 10 et d'une trappe 11 en forme de lame incurvée.The second element is a guiding device 9 essentially composed of a sleeve 10 and a hatch 11 in the form of a curved blade.

La trappe 11 est soudée sur une barre 12 portée par deux barres mobiles 13, 14 articulées selon un axe xx' situé au-dessus de la manchette 10, sur deux bras fixes 15, 16 solidaires de la manchette 10 et soudés extérieurement sur les faces latérales de celle-ci.The hatch 11 is welded on a bar 12 carried by two movable bars 13, 14 hinged along an axis xx 'located above the sleeve 10, on two fixed arms 15, 16 integral with the sleeve 10 and welded externally on the faces. side of it.

La manoeuvre de la trappe 11 ainsi que la structure des pièces secondaires du dispositif de guidage 9 ne sont pas développés davantage dès lors qu'ils sont largement décrits dans le brevet européen publié sous le n° 1.449.984 auquel il pourra utilement être fait référence puisqu'il fait partie de l'état de la technique.The operation of the hatch 11 as well as the structure of the secondary parts of the guide device 9 are not further developed since they are widely described in the European patent published under No. 1449984 which can usefully be referred to as part of the state of the art.

Enfin, le troisième élément de l'ensemble est constitué d'une enveloppe anti-souillures 17 de section tronpyramidale qui peut être montée par son axe arrière 18 dans le creux 19 de deux bras 20 soudés à l'arrière de la manchette 10.Finally, the third element of the assembly consists of an anti-contamination envelope 17 of tronpyramidal section which can be mounted by its rear axis 18 in the hollow 19 of two arms 20 welded to the rear of the sleeve 10.

A l'avant de cette enveloppe 17, un dispositif 21 de serrage rapide permet de bloquer ladite enveloppe sur le dispositif de guidage 9.At the front of this envelope 17, a rapid clamping device 21 makes it possible to block said envelope on the guiding device 9.

Une bride carrée 22 entourant l'ouverture de sortie de la cuve 2 est apte à coopérer avec une bride carrée correspondante 23 soudée en partie supérieure de la manchette 10. Les deux brides 22, 23 sont assemblées l'une à l'autre au moyen de quatre boulons.A square flange 22 surrounding the outlet opening of the tank 2 is adapted to cooperate with a corresponding square flange 23 welded at the upper part of the sleeve 10. The two flanges 22, 23 are assembled to one another by means of four bolts.

Ainsi, le dispositif de guidage 9 est aisément séparable de la cuve 2 de la benne 1 en cas de défectuosité ou pour les besoins d'un lavage du dispositif de guidage 9.Thus, the guiding device 9 is easily separable from the tank 2 of the bucket 1 in the event of a defect or for the purposes of washing the guiding device 9.

L'invention propose d'agencer un tel dispositif de guidage 9, de sorte qu'il reçoive sans aucune exception tous les moyens permettant, à l'aide d'une radiocommande, d'agir sur la trappe 11 afin de faire passer cette dernière d'une position de distribution dans laquelle la trappe 11 est rétractée, et l'ouverture 8 est donc largement ouverte, à une position d'interruption d'écoulement dans laquelle la trappe 11 recouvre entièrement l'ouverture 8, et inversement.The invention proposes to arrange such a guiding device 9, so that it receives without any exception all the means allowing, with the aid of a radio remote control, to act on the hatch 11 in order to pass the latter. a position of distribution in which the hatch 11 is retracted, and the opening 8 is thus largely open, at a flow interruption position in which the door 11 completely covers the opening 8, and vice versa.

Pour cela, on utilise un vérin électrique 24 du type linéaire, à billes, dont les deux extrémités utiles de la tige 25 sont montées articulées respectivement sur un axe 26 situé sensiblement à mi-longueur du bras mobile 13, et sur un axe 27 soudé sur une bride 28 constituant un support du pied du vérin.For this, use is made of an electric jack 24 of the linear ball type, the two useful ends of the rod 25 are mounted hinged respectively on an axis 26 located substantially midway length of the movable arm 13, and on a welded axis 27 on a flange 28 constituting a support of the foot of the jack.

Sur une plaque 29 soudée sur la face avant de la manchette 10, on dispose côte à côte une batterie 30, de 24 volts par exemple, et une armoire électrique de commande 31 reliée à la source d'énergie 30 et au moteur commandant la rotation de la vis du vérin 24, ladite armoire étant reliée sans fil à un élément de radiocommande (non représenté).On a plate 29 welded on the front face of the sleeve 10, there is placed side by side a battery 30, 24 volts for example, and an electrical control cabinet 31 connected to the power source 30 and the motor controlling the rotation of the jack screw 24, said cabinet being connected wirelessly to a radio control element (not shown).

Le vérin est par exemple un vérin linéaire fabriqué par la société suédoise Thomson et commercialisé sous la marque Electrak, par exemple du type D24-05B5-04MON47, qui fournit à pleine charge une force s'élevant à 2.250 N, dont la course utile est de 101,6 mm et la longueur rétractée de 302,3 mm.The jack is for example a linear cylinder manufactured by the Swedish company Thomson and marketed under the brand Electrak, for example of the type D24-05B5-04MON47, which provides a fully loaded force of 2,250 N, whose useful stroke is of 101.6 mm and the retracted length of 302.3 mm.

Ce vérin a l'avantage de se débrayer automatiquement en cas de surcharge et lorsque la trappe arrive en fin de course, aussi bien en ouverture qu'en fermeture.This cylinder has the advantage of disengaging automatically in case of overload and when the hatch reaches the end of the race, both opening and closing.

Le fonctionnement du dispositif de guidage 9 est le suivant : avant de remplir la benne, on met l'armoire électrique sous tension et on vérifie la charge de la batterie ; on pousse sur l'interrupteur de la télécommande pour mettre celle-ci sous tension et on appuie une seconde fois pour la mettre en marche ; enfin, on appuie sur le bouton de fermeture de la trappe pour vérifier la fermeture de celle-ci avant son remplissage ; lorsque la benne est placée au-dessus de l'emplacement de coulage, on commande l'ouverture de la trappe à l'aide de la télécommande radio et, lorsque toute la masse de béton est déversée, on appuie sur le bouton de fermeture de trappe de la télécommande.The operation of the guiding device 9 is as follows: before filling the bucket, the electrical cabinet is turned on and the charge of the battery is checked; pushing the switch on the remote control to turn on the power and press a second time to turn it on; finally, we press the closing button of the hatch to verify the closure thereof before filling; when the bucket is placed above the pouring location, it is necessary to open the hatch using the radio remote control and, when the entire mass of concrete is poured, the closing button is pressed. remote control hatch.

L'ouverture et la fermeture de la trappe se font exclusivement par la commande radio.The opening and closing of the hatch is done exclusively by radio control.

Dans le cas d'un effort anormal, le limiteur de couple du vérin se déclenche pour protéger le mécanisme.In the case of abnormal force, the cylinder torque limiter trips to protect the mechanism.

En cas de panne électrique, et si besoin est, la benne reposant alors sur le sol par son piétement, on dévisse l'écrou qui fixe la tige du vérin 24 sur l'axe 26, on dévisse également l'écrou solidarisant le bras mobile 13 et le bras fixe 15 et, enfin, on place un levier de secours 32 en forme d'équerre (voir figures 9 et 10), la petite branche de cette équerre étant percée de deux orifices disposés en correspondance avec les deux écrous qui ont été dévissés et la grande branche de cette équerre permettant, sous la poussée, d'actionner l'ouverture ou la fermeture de la trappe 11 par rotation des bras mobiles 13, 14 relativement aux bras fixes 15, 16.In case of power failure, and if necessary, the bucket then resting on the ground by its base, unscrewing the nut that fixes the rod of the cylinder 24 on the axis 26, it also unscrews the nut solidarisant the movable arm 13 and the fixed arm 15 and, finally, is placed a spare lever 32 in the form of a square (see figures 9 and 10 ), the small branch of this bracket being pierced with two holes arranged in correspondence with the two nuts which have been unscrewed and the large branch of this bracket allowing, under the pressure, to actuate the opening or closing of the hatch 11 by rotation of the movable arms 13, 14 relative to the fixed arms 15, 16.
