Abstract
Description
L'invention concerne un dispositif de stockage et de manutention de granulats pour un chantier de construction et en particulier pour un chantier routier.The invention relates to a device for storing and handling aggregates for a construction site and in particular for a road site.
Sur les chantiers routiers ou autoroutiers, on utilise des granulats de natures et de dimensions différentes, par exemple pour la fabrication de matériaux de revêtement tels que des enrobés à chaud.On road or motorway construction sites, aggregates of different types and sizes are used, for example for the manufacture of coating materials such as hot mixes.
Les enrobés à chaud sont généralement élaborés dans un dispositif appelé tambour-sécheur-enrobeur à l'entrée duquel on amène en continu des granulats en quantités déterminées et suivant un dosage granulométrique défini.Hot mixes are generally produced in a device called drum-drier-coating at the inlet of which aggregates are continuously supplied in determined quantities and according to a defined particle size dosage.
Les granulats de différents types sont stockés dans des trémies placées successivement l'une à la suite de l'autre pour constituer une ligne de trémies sous laquelle les granulats sont prélevés en quantités dosées. Un mélange de composition définie est amené à l'entrée du tambour par un convoyeur peseur permettant de déterminer de façon précise le débit massique des granulats introduits dans le tambour.The aggregates of different types are stored in hoppers placed successively one after the other to form a line of hoppers under which the aggregates are taken in metered quantities. A mixture of defined composition is brought to the inlet of the drum by a weighing conveyor making it possible to precisely determine the mass flow rate of the aggregates introduced into the drum.
Des quantités bien déterminées de pulvérulent sont également amenées au convoyeur peseur et incorposées au mélange de granulats.Well-defined quantities of pulverulent are also brought to the weighing conveyor and incorporated into the aggregate mixture.
Les chantiers routiers étant essentiellement des chantiers mobiles, on a cherché à simplifier et à faciliter au maximum le transport des différents dispositifs utilisés sur ces chantiers.Since road construction sites are essentially mobile construction sites, attempts have been made to simplify and facilitate the transport of the various devices used on these construction sites as much as possible.
C'est ainsi qu'on a proposé des matériels comportant un châssis monté sur roues et muni de béquilles d'appui au sol portant la ligne de trémies, le nombre de trémies étant généralement de l'ordre de quatre et la longueur totale du châssis étant de l'ordre de vingt mètres.Thus, equipment has been proposed comprising a chassis mounted on wheels and fitted with ground support crutches carrying the line of hoppers, the number of hoppers generally being of the order of four and the total length of the chassis. being of the order of twenty meters.
Le convoyeur peseur est généralement constitué par un convoyeur à bande qui peut être transporté par camion et mis en place en position inclinée sur le chantier, entre la sortie de la ligne de trémies et l'entrée du tambour-sécheur-enrobeur. La sortie de la ligne de trémies est à un niveau situé peu au-dessus du sol cependant que le tapis d'enfournement du tambour-sécheur-enrobeur est à un niveau de l'ordre de trois mètres au-dessus du sol ou un peu plus.The weighing conveyor is generally made up of a belt conveyor which can be transported by truck and set up in an inclined position on the site, between the exit from the line of hoppers and the entry of the drum-dryer-wrapper. The output from the hopper line is at a level slightly above the ground, while the drum-dryer-coating conveyor belt is at a level of the order of three meters above the ground or a little more.
A l'ouverture du chantier, les trémies de stockage et le convoyeur doseur sont mis en place de façon à assurer l'alimentation du tambour-sécheur-enrobeur.At the opening of the site, the storage hoppers and the dosing conveyor are set up so as to ensure the supply of the drum-dryer-wrapper.
Le convoyeur doseur doit être disposé et réglé en fonction de la position des trémies et du tambour-sécheur-enrobeur. La manutention et la mise en place du convoyeur requièrent la présence d'une machine de levage sur le chantier. Le réglage d'inclinaison du convoyeur peut être effectué grâce à des béquilles prenant appui au sol.The dosing conveyor must be arranged and adjusted according to the position of the hoppers and the drum-dryer-wrapper. The handling and installation of the conveyor requires the presence of a lifting machine on the site. The inclination of the conveyor can be adjusted by means of crutches resting on the ground.
Le transport, la manutention et la mise en place des divers éléments du chantier nécessaires pour alimenter le tambour en granulats sont donc des opérations relativement longues et nécessitant l'utilisation de matériels annexes.The transport, handling and installation of the various elements of the site necessary to supply the drum with aggregates are therefore relatively long operations and requiring the use of additional equipment.
Le but de l'invention est donc de proposer un dispositif de stockage et de transfert de granulats pour chantiers de construction, en particulier pour chantiers routiers, assurant le stockage de granulats de natures différentes et leur transport en quantités dosées à l'entrée d'un poste d'utilisation, ce dispositif pouvant être facilement transporté, manutentionné et mis en place sur un chantier mobile.The object of the invention is therefore to propose a device for the storage and transfer of aggregates for construction sites, in particular for road construction sites, ensuring the storage of aggregates of different natures and their transport in quantities dosed at the entry of a use station, this device being able to be easily transported, handled and installed on a mobile site.
Dans ce but, le dispositif suivant l'invention comporte :
- un châssis unique allongé monté sur roues et muni de béquilles extensibles et rétractables pour son appui au sol,
et, montés sur ce châssis,
- au moins deux trémies disposées l'une à la suite de l'autre dans la direction longitudinale du châssis constituant une ligne de trémies,
- un transporteur continu longitudinal disposé suivant la ligne de trémies en dessous de l'ouverture de sortie inférieure de ces trémies,
- un convoyeur peseur incliné par rapport au plan horizontal et disposé suivant la longueur du châssis en parallèle par rapport à la ligne de trémies,
- et un transporteur continu de direction transversale pour le transfert de granulats entre la sortie du transporteur longitudinal et une extrémité du convoyeur peseur constituant sa partie la plus basse.To this end, the device according to the invention comprises:
- a single elongated chassis mounted on wheels and fitted with extendable and retractable crutches for its support on the ground,
and, mounted on this chassis,
- at least two hoppers arranged one after the other in the longitudinal direction of the chassis constituting a line of hoppers,
a longitudinal continuous conveyor disposed along the line of hoppers below the lower outlet opening of these hoppers,
- a weighing conveyor inclined with respect to the horizontal plane and arranged along the length of the chassis in parallel with respect to the line of hoppers,
- And a continuous conveyor in transverse direction for the transfer of aggregates between the outlet of the longitudinal conveyor and one end of the weighing conveyor constituting its lowest part.
Afin de bien faire comprendre l'invention, on va maintenant décrire, à titre d'exemple non limitatif, en se référant aux figures jointes en annexe, un dispositif de stockage et de transfert suivant l'invention utilisé pour l'approvisionnement d'un tambour-sécheur-enrobeur.
- La figure 1 représente une vue latérale en élévation de l'ensemble du dispositif.
- La figure 2 représente une vue de devant en élévation suivant 2 de la figure 1.
- Figure 1 shows a side elevational view of the entire device.
- FIG. 2 represents a front view in elevation along 2 of FIG. 1.
Sur les figures 1 et 2, on voit l'ensemble du dispositif suivant l'invention qui comporte un châssis allongé 1 monté sur des roues 2 et solidaire d'une structure d'attelage 3 permettant son raccordement à un véhicule tracteur à l'extrémité du châssis 1 opposée aux roues 2. Le dispositif conçu sous une forme semi-remorque peut être transporté sur route dans sa configuration représentée sur la figure 1. Sur le châssis sont fixées d'autre part des béquilles d'appui au sol 4 régulièrement réparties suivant la longueur du châssis 1. Les béquilles 4 extensibles et rétractables permettent de réaliser par leur extension l'appui au sol du dispositif sur le chantier, les roues étant soulevées au-dessus du sol lorsque les béquilles sont dans leur position d'extension complète.In Figures 1 and 2, we can see the entire device according to the invention which comprises an elongated frame 1 mounted on
Le châssis 1 comporte également une structure de support verticale 5 constituée par des ensembles réalisés à partir de profilés fixés sur chacun des côtés latéraux du châssis 1.The chassis 1 also comprises a
La structure 5 permet la suspension et la fixation de quatre trémies 6 disposées successivement l'une à la suite de l'autre suivant la longueur du châssis 1.The
Les trémies 6 sont de capacité sensiblement égale et sont susceptible de renfermer chacune une réserve de granulats qui est chargée dans la trémie, sur le chantier, depuis l'un des côtés du châssis.The
Un transporteur à bande continu 8 est fixé sur le châssis 1 suivant toute sa longueur, à la verticale et en dessous des goulottes de sortie 9 des trémies 6.A continuous belt conveyor 8 is fixed to the chassis 1 along its entire length, vertically and below the outlet troughs 9 of the
Lorsqu'une goulotte 9 est mise en position ouverte de déversement, le granulat contenu dans la trémie 6 correspondante s'écoule à débit constant sur le tapis transporteur du convoyeur 8. Le convoyeur 8 permet de transporter le granulat vers la partie avant du châssis 1.When a chute 9 is placed in the open discharge position, the aggregate contained in the
Sur le châssis 1 est également fixé, en parallèle par rapport à la ligne de trémies 6, un convoyeur peseur 10 placé dans une position inclinée par rapport au plan horizontal. Le convoyeur peseur 10 est fixé sur un côté latéral du châssis 1 et sur la structure verticale, latéralement et à l'extérieur du côté latéral correspondant du châssis 1.On the chassis 1 is also fixed, parallel to the
La partie la plus basse du convoyeur 10 est située à l'avant du châssis 1, au niveau de la partie terminale du convoyeur 8 qui est inclinée vers le haut.The lowest part of the
Un convoyeur 11 de direction transversale est également fixé sur le châssis 1 à sa partie antérieure. Ce convoyeur 11 permet de joindre la zone de déversement du convoyeur 8 à une zone située à l'aplomb et au-dessus de la partie inférieure du convoyeur 10.A
Les granulats prélevés dans une trémie 6 sont donc susceptibles de passer du convoyeur 8 au convoyeur 10 par l'intermédiaire du convoyeur transversal 11 qui est incliné vers le haut depuis sa partie située en-dessous du transporteur 8 jusqu'à sa partie située au-dessus du convoyeur 10, c'est-à-dire de l'intérieur vers l'extérieur du châssis 1.The aggregates taken from a
Le convoyeur peseur 10 est fixé en position latérale sur le châssis 1 et la structure de support 5, sur toute la longueur du châssis, de manière que sa partie d'extrémité 10a constituant la partie la plus haute du convoyeur soit en saillie par rapport à l'extrémité arrière du châssis. Cette partie d'extrémité 10a du convoyeur 10 constituant sa partie de déversement peut être placée dans une position telle que l'extrémité de déversement du convoyeur soit située au-dessus du tapis enfourneur 13 d'un tambour-sécheur-enrobeur. Cette position représentée en traits pleins sur la figure 1 correspond à la position en service du convoyeur permettant l'alimentation du tambour.The weighing
La partie d'extrémité 10a du convoyeur 10 peut également être placée dans une position repliée 10′a représentée en traits interrompus sur la figure 1. Cette position 10′a correspond à la position de transport sur route du dispositif dont la longueur est ainsi réduite par rapport à la longueur en position de service sur le chantier.The
Dans le cas d'un dispositif comportant quatre trémies d'une capacité voisine de dix tonnes, la longueur hors tout sur route de la semi-remorque est de l'ordre de 18 mètres.In the case of a device comprising four hoppers with a capacity close to ten tonnes, the overall length on the road of the semi-trailer is of the order of 18 meters.
La longueur du convoyeur 10 qui est elle-même supérieure à 18 mètres permet une alimentation du tapis enfourneur 13 d'un tambour-sécheur-enrobeur à un niveau situé à une hauteur h supérieure à 4 mètres au-dessus du sol du chantier, avec une pente très faible par rapport au plan horizontal.The length of the
Le convoyeur peseur 10 comporte des moyens de pesée continus permettant de déterminer avec précision le débit massique de granulats déversé sur le tapis enfourneur 13 et introduit dans le tambour.The weighing
Les granulats peuvent être déversés sur le tapis du transporteur 8, à partir d'une ou plusieurs trémies 6, ces granulats étant ensuite repris par le transporteur transversal 11, puis le convoyeur peseur 10, pour être déversés sur le tapis enfourneur 13 du tambour.The aggregates can be poured onto the conveyor belt 8, from one or
Les trémies 6 peuvent être vidées successivement par déversement sur le transporteur 8, le remplissage de l'une des trémies pouvant être effectué pendant que le déversement est assuré par une autre trémieThe
Le dispositif permet également d'alimenter le tambour, soit simultanément, soit successivement, avec des granulats de natures différentes.The device also makes it possible to feed the drum, either simultaneously or successively, with aggregates of different natures.
Dans tous les cas, une alimentation et un fonctionnement en continu du tambour peuvent être assurés.In all cases, continuous feeding and operation of the drum can be ensured.
La mise en place du dispositif sur le chantier est extrêmement simple, ce dispositif étant amené dans sa position de travail par le tracteur ayant assuré son transport sur route, puis fixé en position de travail par descente des béquilles 4 et soulévèment du châssis 1 de manière que le train de roues 2 ne soit plus en contact avec le sol. L'extrémité du convoyeur peseur 10 est amené de sa position 10′a à sa position relevée 10a préalablement à la mise en place du dispositif.The installation of the device on the site is extremely simple, this device being brought into its working position by the tractor having ensured its transport on the road, then fixed in the working position by lowering the crutches 4 and lifting the chassis 1 so that the
Après chargement des trémies 6, le dispositif est prêt à fonctionner. La mise en place ne nécessite aucune grue ni aucun moyen de levage annexe et peut être réalisée très rapidement.After loading the
Lorsqu'on réalise le transfert du matériel d'un chantier à un autre, le transport sur route de l'ensemble de stockage et de manutention du granulat peut être réalisé grâce à un tracteur attelé à la partie antérieure du châssis 1, sans qu'il soit nécessaire de réaliser le démontage et le chargement d'une partie du dispositif.When the material is transferred from one site to another, the road transport of the aggregate storage and handling assembly can be carried out using a tractor hitched to the front part of the chassis 1, without it is necessary to dismantle and load part of the device.
D'autre part, l'extrémité de déversement du convoyeur peseur peut être placée sur le chantier à une hauteur importante, bien que la pente de ce convoyeur peseur soit faible. L'encombrement en longueur du dispositif correspond pratiquement à la longueur de la ligne de trémies et son encombrement en largeur n'est que très légèrement supérieur à la largeur maximale des trémies.On the other hand, the discharge end of the weighing conveyor can be placed on the site at a significant height, although the slope of this weighing conveyor is slight. The overall length of the device corresponds practically to the length of the line of hoppers and its overall width is only very slightly greater than the maximum width of the hoppers.
La hauteur de déversement H du dispositif qui peut être relativement importante permet de réa liser des prélèvements de granulats au niveau du tapis enfourneur, avant l'entrée de ces granulats dans le tambour-sécheur-enrobeur.The dumping height H of the device which can be relatively large makes it possible to react read samples of aggregates at the conveyor belt, before the entry of these aggregates into the drum-dryer-coating.
Le dispositif selon l'invention peut permettre le stockage et la manutention de granulats de types différents et peut être réalisé suivant des formes variées avec des capacités différentes.The device according to the invention can allow the storage and handling of aggregates of different types and can be produced in various forms with different capacities.
L'invention ne se limite pas au mode de réalisation qui a été décrit.The invention is not limited to the embodiment which has been described.
C'est ainsi que les transporteurs et convoyeurs de manutention peuvent être réalisés sous des formes variées. Le châssis lui-même, ses moyens de roulement et d'appui au sol et sa structure de support verticale peuvent être réalisés de manière différente de celles qui ont été décrites.This is how transporters and handling conveyors can be produced in various forms. The chassis itself, its rolling and ground support means and its vertical support structure can be produced in a manner different from those which have been described.
Enfin, le dispositif suivant l'invention peut permettre non seulement d'alimenter un tambour-sécheur-enrobeur en granulats mais encore tout autre poste d'utilisation de tels granulats.Finally, the device according to the invention can make it possible not only to supply a drum-dryer-coater with aggregates but also any other station for using such aggregates.
