Abstract

The device for handling materials in bulk, held in a wagon, is constructed such that the body (3) of the wagon is fitted, on its lower part, with a semi-cylindrical sheet steel (16) panel, of which the diameter is equal to the width of the wagon and to the diameter of the peripheral part of the wheel (10). The wheel carries the buckets or scoops (11), which act as a countersink borer. The wheel is supported by a suspension frame (6), which is designed to ensure that the wheel is displaced axially along the useful length of the wagon. The wagon is also fitted with a transporter system (8), which extends axially and passes to the interior of the wheel.

Description

La présente invention concerne la manutention des charges en vrac pouvant être contenues dans des wagons tombereaux.The present invention relates to the handling of loads in bulk which may be contained in dump wagons.

Certaines matières en vrac tendent à s'agglomérer lorsqu'elles séjournent dans des wagons tombereaux qu'il est souvent très difficile de décharger.Certain bulk materials tend to agglomerate when they are in dump cars that it is often very difficult to unload.

C'est le cas notamment des matériaux en vrac ayant servi à la constitution de la plate forme pour voies de chemin de fer. En effet, les pierres sont souvent mélangées à des détritus et sont aussi imprégnées notamment de glaise.This is particularly the case for the bulk materials used for the creation of the platform for railway tracks. Indeed, the stones are often mixed with trash and are also impregnated in particular with clay.

L'ensemble pierres, détritus et glaise humide forme une masse extrêmement compacte en particulier lorsque cette masse est soumise aux vibrations de roulement d'un wagon dans lequel elle a été chargée humide.The set of stones, detritus and wet clay forms a mass extremely compact especially when this mass is subject to the rolling vibrations of a wagon in which it was loaded wet.

Le déchargement des wagons contenant de telles masses s'avère extrêmement difficile même lorsque les wagons tombereaux sont munis d'un système de chargement et déchargement car les systèmes connus jusqu'à présent ne peuvent pas permettre d'entamer la masse compactée.Unloading wagons containing such masses is found extremely difficult even when the dump cars are equipped with a loading and unloading system because the systems known so far cannot allow to start the compacted mass.

Le problème concerné par un tel déchargement a d'ailleurs été bien indiqué dans le document WO 93 23 276 A qui énonce à la page 2, lignes 10-12 que, "du fait que les matériaux sont contenus entre deux parois fixes de la caisse des wagons, le convoyeur est susceptible de n'entraíner qu'une partie des matériaux, l'autre partie demeurant en place par effet de voûte". The problem concerned with such an unloading was moreover well indicated in document WO 93 23 276 A which states at the page 2, lines 10-12 that, "because the materials are contained between two fixed walls of the wagon body, the conveyor is likely to cause only part of the materials, the other part remaining in place by vaulted".

Cependant, le document antérieur ci-dessus ne résoud pas complètement le problème et n'évite pas qu'il est souvent nécessaire d'utiliser des marteaux piqueurs pour permettre la division de la masse compactée.However, the above prior document does not resolve completely the problem and does not avoid that it is often necessary to use jackhammers to allow the division of the compacted mass.

L'invention crée un nouveau dispositif qui rend possible le déchargement de masses de compacité quelconque sans intervention manuelle.The invention creates a new device which makes possible the unloading of masses of any compactness without intervention manual.

Conformément à l'invention, le dispositif de manutention d'une charge de produits en vrac contenue dans un wagon est caractérisé en ce que la caisse est munie, à sa partie basse, d'une tôle de forme semi-cylindrique dont le diamètre correspond à la largeur intérieure du wagon et au diamètre de la partie périphérique d'une roue comportant des augets à fonction de fraise, lesdits augets débordant latéralement pour constituer des couteaux pénétrant dans la charge de produits en vrac et ladite roue étant supportée par un portique assurant son déplacement axial sur toute la partie utile de chargement du wagon.According to the invention, the device for handling a load of bulk products contained in a wagon is characterized in that that the body is provided, in its lower part, with a sheet of semi-cylindrical shape whose diameter corresponds to the inner width of the wagon and the diameter of the part peripheral of a wheel comprising buckets with a function of strawberry, said buckets projecting laterally to constitute knives penetrating the load of bulk products and said wheel being supported by a gantry ensuring its movement axial over the entire useful loading part of the wagon.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other features of the invention emerge moreover from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé.One embodiment of the subject of the invention is shown, by way of nonlimiting example, in the drawing Annex.

La fig. 1 est une élévation latérale d'un wagon tombereau faisant application de l'invention.Fig. 1 is a side elevation of a dump wagon applying the invention.

La fig. 2 est une élévation d'extrémité correspondant à la fig. 1.Fig. 2 is an end elevation corresponding to the Fig. 1.

La fig. 3 est une coupe schématique très agrandie vue sensiblement suivant la ligne III-III de la fig. 1. Fig. 3 is a very enlarged schematic section seen substantially along line III-III of FIG. 1.

La fig. 1 illustre un wagon-tombereau 1 porté par des bogies 2. Le wagon 1 comporte une caisse 3 avec des bords latéraux formant chacun un chemin de roulement 4 à crémaillère pour des galets 5 d'un portique 6 déplaçable axialement sur toute la longueur de la cuve 7 délimitée par la caisse 3 du wagon.Fig. 1 illustrates a dump car 1 carried by bogies 2. Wagon 1 has a box 3 with side edges each forming a rack raceway 4 for rollers 5 of a gantry 6 movable axially over all the length of the tank 7 delimited by the body 3 of the wagon.

D'une manière connue en elle-même, le wagon est muni, à la partie haute de sa caisse, d'un transporteur 8 pour le chargement respectivement le déchargement des produits en vrac devant être contenus dans la cuve 7. Le transporteur 8 est du type à bande et rouleau motorisé ou entraíné par une chaíne ou d'autres moyens bien connus dans la technique.In a manner known in itself, the wagon is provided, at the upper part of its body, a transporter 8 for the loading respectively unloading of products in bulk to be contained in the tank 7. The transporter 8 is of the belt and roller type motorized or driven by a chain or other means well known in the art.

Le wagon est avantageusement muni d'un convoyeur auxiliaire 9 à flèche articulée et pivotante pour que ce convoyeur auxiliaire rende possible la manutention des produits en vrac du transporteur d'un wagon vers celui d'un wagon contigu de même que l'évacuation des produits en vrac du wagon vers l'extérieur.The wagon is advantageously provided with an auxiliary conveyor 9 with articulated and pivoting boom so that this auxiliary conveyor makes it possible to handle bulk products from transporter from a wagon to that of a contiguous wagon similarly that the evacuation of bulk products from the wagon to outside.

Le transporteur 8 de même que le convoyeur auxiliaire 9 étant bien connus en eux-mêmes, ils ne sont pas décrits de façon détaillée. Il doit toutefois être observé qu'il est important que le transporteur 8 soit muni d'une sole escamotable pour permettre selon les besoins :

  • de charger le wagon, la sole étant en position haute et le tapis du transporteur 8 à plat sur la longueur de la sole ;
  • de permettre le passage des produits vers les wagons suivants, la sole étant alors en position basse et le tapis du transporteur 8 conservant alors sa forme en auge.
The conveyor 8 as well as the auxiliary conveyor 9 being well known in themselves, they are not described in detail. It must however be observed that it is important that the conveyor 8 is provided with a retractable sole to allow, as required:
  • load the wagon, the sole being in the high position and the conveyor belt 8 flat along the length of the sole;
  • allow the passage of products to the following wagons, the sole then being in the low position and the conveyor belt 8 then retaining its trough shape.

Le portique 6 supporte une roue 10 à pelles ou augets 11 s'étendant radialement suivant une courbure choisie pour engendrer avec le déplacement longitudinal un effet de fraisage par le bord d'attaque des augets amenés en contact avec la masse d'une charge de produits en vrac devant être travaillée.Gantry 6 supports a wheel 10 with shovels or buckets 11 extending radially along a curvature chosen for generate with the longitudinal displacement an effect of milling by the leading edge of the buckets brought into contact with the mass of a load of bulk products to be worked.

Le dessin illustre schématiquement que la roue comporte dans l'exemple représenté douze augets 11 reliés par des chaínes 12. Les augets 12 débordent latéralement par exemple de 5 cm environ pour constituer des couteaux aidant à pénétrer dans la masse de la charge de produits en vrac. La roue est montée sur une couronne.The drawing schematically illustrates that the wheel has in the example represented twelve buckets 11 connected by chains 12. The buckets 12 extend laterally for example by 5 cm about to form knives helping to penetrate into the mass of the bulk product load. The wheel is mounted on a crown.

La roue est munie sur sa face arrière d'un bouclier arrière 13 s'étendant jusqu'à la partie haute de la caisse 3 du wagon. Le bouclier 13 supporte latéralement une tôle de guidage 14 présentant, un bord inférieur évasé 14a pour faciliter le passage des produits en vrac saisies par les augets successifs.The wheel is provided on its rear face with a rear shield 13 extending to the upper part of the body 3 of the wagon. The shield 13 laterally supports a guide plate 14 having a flared bottom edge 14 a to facilitate the passage of the bulk products seized by the successive buckets.

A son autre extrémité, la tôle 14 forme un déversoir 14b qui s'étend jusqu'au-dessus du transporteur 8, ce déversoir dirigeant les produits en vrac s'écoulant des augets 11 lorsqu'ils se trouvent à la partie supérieure de la trajectoire circonférentielle que parcourt la roue 10.At its other end, the sheet 14 forms a weir 14b which extends to above the conveyor 8, this weir directing the bulk products flowing from the buckets 11 when they are at the top of the circumferential trajectory traversed by the wheel 10.

Pour que la roue 10 agisse comme une fraise, elle est déplacée par des moto-réducteurs 15 (fig. 1), par exemple deux, qui coopèrent avec le chemin de roulement 4 de la partie haute de la caisse 3 du wagon. Pour ce faire le chemin de roulement 4 est muni de crémaillères.In order for wheel 10 to act like a cutter, it is moved by geared motors 15 (fig. 1), for example two, which cooperate with the raceway 4 of the upper part of body 3 of the wagon. To do this the way bearing 4 is fitted with racks.

A titre d'exemple, pour assurer une bonne pénétration de la roue à augets ou roue-pelle décrite ci-dessus, il est avantageux qu'une force de l'ordre de 400 à 500 kN soit exercée sur la masse de la charge de produits en vrac à extraire. For example, to ensure good penetration of the bucket wheel or shovel wheel described above, it is advantageous that a force of the order of 400 to 500 kN is exerted on the mass of the load of bulk products to be extracted.

La fig. 3 montre que le fond du wagon est constitué par une tôle 16 de forme semi-cylindrique venant à proximité immédiate de la partie périphérique des augets 11.Fig. 3 shows that the bottom of the wagon consists of a sheet 16 of semi-cylindrical shape coming in the immediate vicinity of the peripheral part of the buckets 11.

Comme cela ressort de ce qui précède à la fin de chaque cycle de travail, les déblais chargés dans le wagon sont systématiquement repris par la roue pelle, rechargés sur les convoyeurs 8 et envoyés sur le convoyeur 9 orienté pour évacuer ces déblais latéralement en décharge.As is evident from the above at the end of each cycle work, the cuttings loaded in the wagon are systematically taken up by the shovel wheel, recharged on the conveyors 8 and sent on the conveyor 9 oriented for evacuate these cuttings laterally in landfill.

L'espace laissé libre entre la tôle 6 et la caisse 3 est avantageusement mis à profit pour le logement de réservoirs 17 contenant notamment du fuel pour l'alimentation des différents moteurs nécessaires au fonctionnement de la roue-pelle décrite qui est déplacée sur toute la longueur utile du wagon.The space left free between the sheet 6 and the body 3 is advantageously used for housing tanks 17 containing in particular fuel for the supply of different motors necessary for the operation of the excavator wheel described which is moved over the entire useful length of the car.

La réalisation décrite ci-dessus fait que les produits en vrac se trouvant dans le wagon peuvent être détachés quelles que soient leur viscosité et leur compacité puisque les augets travaillent comme des fraises.The realization described above means that the products in bulk in the wagon can be detached whatever their viscosity and their compactness since the buckets work like strawberries.

L'invention n'est pas limitée à l'exemple de réalisation, représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre ainsi que cela est défini dans les revendications.The invention is not limited to the embodiment, shown and described in detail because various modifications can be made without departing from its framework as well as this is defined in the claims.
