Abstract
Description
La présente invention est relative à un dispositif de nettoyage de grands containers de transport de produits en vrac tels que des cales de navires. The present invention relates to a device for cleaning large containers for transporting bulk products such as ship's holds.
L'experience a montre que, quels que soient les moyens utilisés pour vider les cales de navires contenant un produit en vrac tel que du charbon, du minerai ou des grains, il y subsiste toujours sur le fond une certaine quantité de produit qu'il convient de ramasser. Experience has shown that, whatever the means used to empty the holds of ships containing a bulk product such as coal, ore or grains, there always remains on the bottom a certain quantity of product which it should pick up.
En l'état actuel de la technique, ce nettoyage s'effectue par des moyens annuels et il est donc particulièrement couteux notamment en raison de la main d'oeuvre nombreuse qu'il nécessite. In the current state of the art, this cleaning is carried out by annual means and it is therefore particularly expensive in particular because of the large workforce it requires.
Selon l'invention qui remédie à cet inconvénient, on utilise une benne qui est descendue dans la cale à nettoyer et maintenue dans un angle de celle-ci, ladite benne dont une face latérale est alors ouverte pour former une rampe d'introduction étant remplie à l'aide d'une pelle tractée, la traction de ladite pelle étant réalisée à l'aide du cale de relevage de ladite benne. According to the invention which overcomes this drawback, a bucket is used which is lowered into the hold to be cleaned and kept at an angle thereof, said bucket, one side face of which is then open to form an introduction ramp being filled. using a towed shovel, the pulling of said shovel being carried out using the lifting wedge of said bucket.
D'autres caractéristiques apparaîtront mieux par la description qui va suivre, faite en se référant aux dessins annexés à titre d'exemple indicatif seulement,sur lesquels:
La figure 1 est une vue en perspective montrant l'utilisation du dispositif;
La figure 2 est une vue de côté à plus grande échelle montrant le mode d'utilisation;
La figure 3 est la vue de dessus de la figure 2;
La figure 4 est une vue de côte montrant la vidange de la benne.Other characteristics will appear better from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is a perspective view showing the use of the device;
Figure 2 is an enlarged side view showing the mode of use;
Figure 3 is the top view of Figure 2;
Figure 4 is a side view showing the emptying of the bucket.
En se reportant à la figure 1, on voit que le problème à résoudre consiste à nettoyer le fond 1 d'un grand container tel qu'une cale 2 de navire. Referring to FIG. 1, it can be seen that the problem to be solved consists in cleaning the bottom 1 of a large container such as a ship's hold 2.
Selon l'invention, on descend dans la cale 2,une benne 3 qui ese suspendue à un câble 4 s'enroulant sur le tambour d'une grue usuelle (non représentée). According to the invention, it descends into the hold 2, a bucket 3 which is suspended from a cable 4 winding on the drum of a conventional crane (not shown).
De préférence, la benne 3 est disposée dans un angle de la cale sur le fond de laquelle elle est fixée au moyen, par exemple, d'aimants 5 ou de ventouses mécaniques. Preferably, the bucket 3 is arranged in a corner of the wedge on the bottom of which it is fixed by means, for example, of magnets 5 or mechanical suction cups.
Une face latérale Q de la benne 3 est constituée par un panneau pouvant pivoter par son bord inférieur jusqu'à ce que celui supérieur 6a puisse reposer sur le fond 1 de la cale en formant ainsi une rampe d'introduction. A side face Q of the bucket 3 is constituted by a panel which can pivot by its lower edge until the upper one 6a can rest on the bottom 1 of the hold, thus forming an introduction ramp.
Durant la montée et la descente de la benne 3, le câble 4 passe sous une poulie 7 auto-orientable située à la partie supérieure de la benne et son extrémité est accrochée à la face interne du panneau 6. During the raising and lowering of the bucket 3, the cable 4 passes under a self-orientable pulley 7 located at the upper part of the bucket and its end is hooked to the internal face of the panel 6.
Lorsque la benne 3 repose sur le fond 1, on décroche le câble 4 ce qui provoque l'ouverture de la benne par le pivotement du panneau 6 et ledit câble est alors accroché à une pelle tractée 8 comportant des mancherons 8a permettant de la guider. When the bucket 3 rests on the bottom 1, the cable 4 is unhooked, which causes the bucket to open by pivoting the panel 6, and the said cable is then attached to a towed shovel 8 comprising handlebars 8a allowing it to be guided.
I1 y a lieu de noter que ce dispositif permet d'effectuer le nettoyage d'une cale à l'aide de deux personnes, l'une étant dans la cale pour guider et déplacer la pelle et l'autre à l'ex- térieur pour commander l'enroulement ou le déroulement du câble sur le tambour de la grue,ces deux personnes étant reliées par radio, ce qui ne pose aucun problème technique
Lorsque la benne est pleine, on décroche la pelle et on fixe -l'extrémité du câble sur la panneau 6.It should be noted that this device makes it possible to carry out the cleaning of a hold using two people, one being in the hold to guide and move the shovel and the other outside. to control the winding or unwinding of the cable on the crane drum, these two people being connected by radio, which poses no technical problem
When the bucket is full, the shovel is removed and the end of the cable is fixed to panel 6.
Après avoir libéré la benne, on actionne le tambour de la grue ce qui a pour effet de tendre le chble 4 , de provoquer la fermeture du panneau 6 de la benne puis son élévation. After having released the bucket, the crane drum is actuated, which has the effect of tightening the chble 4, causing the panel 6 of the bucket to close and then raising it.
Lorsque la benne 3 est sortie de la cale et est située au-dessus de son point de déchargement , on accroche l'extrémité d'une élingue 9 , dont l'autre extrémité est fixée sous la flèche de la grue, en un point 10 situé sensiblement au milieu de la face 3a de la benne à l'opposé du panneau 6 puis on donne du mou au câble 4 ce qui provoque simultanément l'ouverture dudit panneau et le basculement de la benne, comme montré sur la figure 4. When the bucket 3 is removed from the hold and is located above its unloading point, the end of a sling 9 is hooked, the other end of which is fixed under the boom of the crane, at a point 10 located substantially in the middle of the face 3a of the bucket opposite the panel 6, then slack is given to the cable 4 which simultaneously causes the opening of said panel and the tilting of the bucket, as shown in FIG. 4.
Après la vidange de la benne, on tend le câble 4 , on décroche l'élingue 9 et ladite benne peut alors à nouveau être descendue dans la cale. After emptying the bucket, the cable 4 is stretched, the sling 9 is unhooked and said bucket can then again be lowered into the hold.
Selon une autre caractéristique de l'invention, la pelle 8 présente à sa partie arrière une bavette 11 disposée obliquement par rapport au sens de déplacement de la pelle.Cette ba vette a pour fonction de racler le fond de la cale et de repousser latéralement le produit qui aurait échappé à la pelle et qui est ensuite repris par ladite pelle lors du passage suivant. According to another characteristic of the invention, the shovel 8 has at its rear part a flap 11 arranged obliquely to the direction of movement of the shovel. This ba vette has the function of scraping the bottom of the wedge and pushing the product which would have escaped the shovel and which is then taken up by said shovel during the next pass.
I1 ressort des explications ci-dessus que l'originalité du dispositif réside dans les multiples fonctions remplies par le câble 4 qui, outre celle usuelle de permettre la montée et la descente de la benne, permet de commander l'ouverture et la fermeture de cette dernière et d'actionner la pelle. I1 emerges from the above explanations that the originality of the device lies in the multiple functions fulfilled by the cable 4 which, in addition to the usual one to allow the raising and lowering of the bucket, allows to control the opening and closing of this last and operate the shovel.
Bien entendu,la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend,au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
