Description

Description Description
Titre : Dispositif de crochet pour le levage d’un conteneur multimodal. Title: Hook device for lifting a multimodal container.
La présente invention se rapporte au domaine de la manutention de conteneur multimodaux équipé de coins répondant à la norme ISO 1161. Plus particulièrement, le but est de proposer des moyens pour lever un tel conteneur en s’accrochant à ses coins supérieurs, en utilisant des élingues et sans avoir nécessairement besoin d’un palonnier. The present invention relates to the field of handling multimodal containers equipped with corners meeting the ISO 1161 standard. More particularly, the aim is to propose means for lifting such a container by hanging on to its upper corners, using slings and without necessarily needing a lifting beam.
Un coin supérieur selon la norme ISO 1161 est un bloc creux sensiblement parallélépipédique et comprend trois orifices : An upper corner according to the ISO 1161 standard is a substantially parallelepipedal hollow block and comprises three orifices:
- un trou « supérieur », formé dans sa paroi supérieur et allongé selon la direction d’allongement du conteneur ; - an "upper" hole, formed in its upper wall and elongated in the direction of elongation of the container;
- un trou « poire », formé dans sa paroi frontale, parallèle à une paroi transversale du conteneur et allongé verticalement ; et, - a "pear" hole, formed in its front wall, parallel to a transverse wall of the container and elongated vertically; And,
- un trou « ovale », formé dans sa paroi longitudinale, parallèle à une paroi longitudinale du conteneur et allongé verticalement. - an "oval" hole, formed in its longitudinal wall, parallel to a longitudinal wall of the container and elongated vertically.
Dans le cas d’un coin ISO inférieur, le trou supérieur est remplacé par un trou « inférieur » formé dans sa paroi inférieure et allongé selon la direction d’allongement du conteneur In the case of a lower ISO corner, the upper hole is replaced by a "lower" hole formed in its lower wall and elongated according to the direction of elongation of the container
On connait notamment trois types de crochets pour le levage comprenant d’une part des moyens de prise avec des élingues de levage, et, d’autre part, des moyens de prise avec un coin : In particular, three types of lifting hooks are known, comprising, on the one hand, gripping means with lifting slings, and, on the other hand, gripping means with a wedge:
- le type HM/C3, qui vient s’insérer au travers du trou supérieur d’un coin supérieur ; - the HM/C3 type, which is inserted through the upper hole of an upper corner;
- les types C2 et C5, qui sont prévus pour être insérés dans un trou oblong d’un coin inférieur. Les crochets des types C2 et C5 sont prévus pour être accrochés aux coins bas, et ils débordent latéralement, augmentant l’encombrement transversal du conteneur qu’ils équipent. Ils nécessitent l’utilisation d’une traverse ou d’un palonnier ; ils ne peuvent être utilisés avec de simples élingues. Le crochet de type C5 présente un faible niveau de sécurité, et des accidents sont déjà survenus. Le crochet de type C2 peut être équipé d’une option antidécrochement. Dans ces deux cas, la sécurité de la fixation du crochet sur le conteneur est principalement assurée par la tension des élingues de levage ; il y a donc un risque de décrochage lorsqu’une élingue se détend. - types C2 and C5, which are designed to be inserted into an oblong hole in a lower corner. Hooks of types C2 and C5 are designed to be hung at the bottom corners, and they project laterally, increasing the transverse bulk of the container they equip. They require the use of a crosspiece or a lifting beam; they cannot be used with simple slings. The C5 type hook has a low level of safety, and accidents have already occurred. The type C2 hook can be fitted with an anti-unhooking option. In these two cases, the security of the attachment of the hook to the container is mainly ensured by the tension of the lifting slings; there is therefore a risk of unhooking when a sling becomes slack.
Le crochet de type HM/C3 présente aussi de nombreux désavantages ; notamment : The HM/C3 type hook also has many disadvantages; notably :
- il possède une tige verticale très longue qui travaille en flexion, à la fois selon un plan transversal et selon un plan longitudinal du conteneur ; - it has a very long vertical rod which works in bending, both in a transverse plane and in a longitudinal plane of the container;
- la manille de fixation de l’élingue subit des torsions importantes ; - the sling attachment shackle undergoes significant twisting;
- il endommage le coin ISO, notamment par poinçonnement du logement intérieur et des bords du trou supérieur ; et, - it damages the ISO corner, in particular by punching the interior housing and the edges of the upper hole; And,
- il est lourd. - he's heavy.
Le but de l’invention, est de proposer un dispositif de levage : The object of the invention is to provide a lifting device:
- qui puisse s’adapter aisément à une position d’une élingue qui lui est fixée ;- that can be easily adapted to a position of a sling attached to it;
- dont la fixation est assurée même lorsque l’élingue est détendue ; - whose attachment is guaranteed even when the sling is slack;
- qui soit sensiblement inoffensif pour le coin auquel il est fixé ; et, - which is substantially harmless to the corner to which it is fixed; And,
- auquel on puisse laisser une élingue ou une sangle, accrochée en attente. - to which we can leave a sling or a strap, hung on standby.
Pour résoudre ce problème, l'invention propose un dispositif pour lever un conteneur, notamment un conteneur multimodal équipé d’un coin ISO, qui comprend une broche et une plaque d’appui, la broche comprenant : To solve this problem, the invention proposes a device for lifting a container, in particular a multimodal container equipped with an ISO corner, which comprises a spindle and a support plate, the spindle comprising:
- une tige, s’étendant selon un axe de tige ; - a stem, extending along a stem axis;
- des moyens pour accrocher, au moins indirectement, des moyens de levage tels que des élingues ; et, - des moyens pour venir en prise avec la plaque d’appui ; la plaque d’appui étant prévue pour être introduite dans un logement intérieur du coin et comprenant : - Means for hooking, at least indirectly, lifting means such as slings; And, - Means for engaging the support plate; the support plate being intended to be introduced into an interior housing of the corner and comprising:
- un passage pour former un pivot avec une portion libre de la tige, entre les moyens d’accroche et les moyens de prise ; et, - a passage to form a pivot with a free portion of the rod, between the hooking means and the gripping means; And,
- des moyens pour solidariser et désolidariser la plaque de la broche. - Means for securing and disengaging the plate from the spindle.
Les moyens d’accroche comprennent avantageusement un trou d’axe formé dans un plan sensiblement perpendiculaire à l’axe de tige et écarté de l’axe de tige d’une distance nettement non nulle, selon une direction, ce trou étant proche d’une première extrémité de la tige et prévu pour y fixer une manille. The attachment means advantageously comprise an axis hole formed in a plane substantially perpendicular to the rod axis and spaced from the rod axis by a clearly non-zero distance, in one direction, this hole being close to a first end of the rod and provided for attaching a shackle thereto.
Les moyens de prise peuvent comprendre un lardon qui s’étend radialement selon la même direction depuis une deuxième extrémité de la tige opposée à la première extrémité. Les moyens de prise peuvent en outre comprendre un talon qui s’étend dans une direction sensiblement opposée à la direction d’extension du lardon. The gripping means may comprise a gib which extends radially in the same direction from a second end of the rod opposite the first end. The gripping means may further comprise a heel which extends in a direction substantially opposite to the direction of extension of the gib.
Les moyens d’accroche peuvent comprendre une première surface et les moyens de prise comprendre une deuxième surface, en vis à vis l’une de l’autre et sensiblement perpendiculaires à l’axe de tige. Avantageusement, la portion libre s’étend axialement entre la première et la deuxième surface. The attachment means may comprise a first surface and the gripping means comprise a second surface, facing each other and substantially perpendicular to the stem axis. Advantageously, the free portion extends axially between the first and the second surface.
De préférence, la plaque comprend un corps et un verrou, le corps et le verrou formant ensemble le passage, le verrou pouvant prendre une position ouverte dans laquelle la portion libre peut être introduite radialement dans le passage et une position fermée, dans laquelle le passage et la portion libre forment le pivot. Preferably, the plate comprises a body and a latch, the body and the latch together forming the passage, the latch being able to assume an open position in which the free portion can be introduced radially into the passage and a closed position, in which the passage and the free portion form the pivot.
La plaque comprend avantageusement une surface prévue pour venir en appui sur une paroi supérieure du coin. Plusieurs modes d’exécution de l’invention seront décrits ci-après, à titre d’exemples non limitatifs, en référence aux dessins annexés dans lesquels : The plate advantageously comprises a surface intended to bear against an upper wall of the corner. Several embodiments of the invention will be described below, by way of non-limiting examples, with reference to the appended drawings in which:
[Fig. 1] est une vue schématique en élévation et perspective, d’un dispositif de levage selon l’invention, équipé d’une manille ; [Fig. 1] is a schematic view in elevation and perspective, of a lifting device according to the invention, equipped with a shackle;
[Fig. 2] est une vue schématique en élévation et perspective, du dispositif de la figure 1, en position dans un coin ISO dont une partie a été coupée pour y faire apparaitre une partie du dispositif à l’intérieur de ce coin ; [Fig. 2] is a schematic view in elevation and perspective, of the device of Figure 1, in position in an ISO corner, part of which has been cut to reveal part of the device inside this corner;
[Fig. 3] est une vue similaire à la figure 2, selon un autre angle de vue, dans laquelle le coin a été coupé longitudinalement ; et, [Fig. 3] is a view similar to Figure 2, from another angle, in which the corner has been cut longitudinally; And,
[Fig. 4] est une vue schématique éclatée du dispositif de levage de la figure 1. [Fig. 4] is an exploded schematic view of the lifting device of Figure 1.
Les termes vertical et horizontal s’appliquent arbitrairement à la position du dispositif à la figure 1 et un conteneur supposé posé sur un plan horizontal. Pour un coin du conteneur, on appelle longitudinal ce qui s’étend selon la longueur du conteneur et on appelle transversal ce qui s’étend selon la largeur du conteneur. The terms vertical and horizontal apply arbitrarily to the position of the device in Figure 1 and a container assumed to be resting on a horizontal plane. For a corner of the container, we call longitudinal what extends along the length of the container and we call transverse what extends along the width of the container.
La figure 1 illustre un dispositif 1 pour le levage d’un conteneur multimodal répondant aux normes ISO 668 et ISO 1496 et équipé de coins dits « ISO » répondant à la norme ISO 1161, sans que cela puisse être considéré comme limitatif. Figure 1 illustrates a device 1 for lifting a multimodal container meeting the ISO 668 and ISO 1496 standards and equipped with so-called "ISO" corners meeting the ISO 1161 standard, without this being considered limiting.
Le dispositif 1 de la figure 1 est équipé d’une manille 2 qui permet d’y fixer une élingue d’un engin de levage ; cet engin peut être une grue. Le dispositif comprend une plaque 3 et une broche 4. Comme illustré aux figures 2 et 3, le dispositif est prévu pour venir en prise avec un coin 6 supérieur d’un conteneur ; aux figures, seul le coin 6 est représenté, le reste du conteneur ne l’est pas. The device 1 of Figure 1 is equipped with a shackle 2 which makes it possible to attach a sling of a lifting device to it; this machine can be a crane. The device comprises a plate 3 and a pin 4. As shown in Figures 2 and 3, the device is designed to come into engagement with an upper corner 6 of a container; in the figures, only corner 6 is shown, the rest of the container is not.
Le coin 6 a une forme extérieure sensiblement parallélépipédique, dont les parois définissent un logement 7, lui aussi sensiblement parallélépipédique. Le coin comprend une paroi supérieure 11, dans laquelle est formé un trou supérieur 12 oblong allongé dans le sens longitudinal SL, une paroi transversale 13, dans laquelle est formé un trou frontal 14, appelé trou « poire » et une paroi longitudinale 15, dans laquelle est formé un trou latéral 16, appelé trou « ovale ». La paroi supérieure l i a une épaisseur sensiblement constante El i. The corner 6 has a substantially parallelepipedal outer shape, the walls of which define a housing 7, also substantially parallelepipedal. THE corner comprises an upper wall 11, in which is formed an upper oblong hole 12 elongated in the longitudinal direction SL, a transverse wall 13, in which is formed a front hole 14, called "pear" hole and a longitudinal wall 15, in which is formed a side hole 16, called "oval" hole. The upper wall bound a substantially constant thickness El i.
Les trois autres parois du coin 6 sont aveugles et tournées vers l’intérieur du conteneur. The other three walls of corner 6 are blind and facing the inside of the container.
Comme illustré aux figures 2 et 3, la plaque 3 est prévue pour être disposée dans le logement 7 et pour retenir la broche 4 en prise avec le coin 6. La plaque est séparable de la broche et ses dimensions sont telles qu’elle peut être introduite isolément dans le logement 7 par l’un des trous 12, 14, 16, puis accouplée avec la broche, de sorte qu’ainsi accouplée, la broche soit maintenue en prise avec le coin 6. As illustrated in Figures 2 and 3, the plate 3 is provided to be arranged in the housing 7 and to retain the pin 4 in engagement with the wedge 6. The plate is separable from the pin and its dimensions are such that it can be introduced separately into the housing 7 through one of the holes 12, 14, 16, then coupled with the pin, so that thus coupled, the pin is kept in engagement with the wedge 6.
Comme illustré à la figure 4, la broche 4 comprend une tige 20 sensiblement cylindrique, une chape 21 et un lardon 22. La tige 20 est sensiblement cylindrique autour d’un axe de tige X20. La chape 21 a une forme de plaque qui s’étend radialement, selon une direction D4, depuis une partie supérieure de la tige 20, c’est-à-dire à une première extrémité de la tige. Le lardon 22 s’étend radialement, sensiblement selon la même direction D4, depuis la base de la tige 20, c’est-à-dire à une deuxième extrémité de la tige opposée à la première. As illustrated in Figure 4, the spindle 4 comprises a substantially cylindrical rod 20, a yoke 21 and a gib 22. The rod 20 is substantially cylindrical around a rod axis X20. The yoke 21 has the shape of a plate which extends radially, in a direction D4, from an upper part of the rod 20, that is to say at a first end of the rod. The gib 22 extends radially, substantially in the same direction D4, from the base of the rod 20, that is to say at a second end of the rod opposite the first.
Un trou 23 est formé au travers la chape 21, pour y fixer la manille 2. Le trou est cylindrique autour d’un axe horizontal X23 ; cet axe est formé dans un plan perpendiculaire à l’axe de tige X20 et écarté de l’axe de tige X20 d’une distance E23 non nulle. La chappe forme une surface inférieure 26 et le lardon 22 forme une surface supérieure 27, en vis-à-vis l’une de l’autre, toutes deux perpendiculaires à l’axe de tige X20 et écartée l’une de l’autre d’une distance La plaque d’appui 3 a une épaisseur E3 sensiblement constante, mesurée entre une face supérieure 28 et une face inférieure 29. Comme illustré à la figure 4, elle comprend un corps 30, un verrou 31 et un pivot 32. Le corps est ouvert dans une face longitudinale 41 de la plaque 3. Le pivot est prévu pour articuler le verrou avec le corps, autour d’un axe vertical X32. A hole 23 is formed through the clevis 21, to fix the shackle 2 there. The hole is cylindrical around a horizontal axis X23; this axis is formed in a plane perpendicular to the stem axis X20 and separated from the stem axis X20 by a non-zero distance E23. The yoke forms a lower surface 26 and the gib 22 forms an upper surface 27, facing each other, both perpendicular to the stem axis X20 and separated from each other by a distance The support plate 3 has a substantially constant thickness E3, measured between an upper face 28 and a lower face 29. As illustrated in Figure 4, it comprises a body 30, a lock 31 and a pivot 32. The body is open in a longitudinal face 41 of the plate 3. The pivot is provided to articulate the lock with the body, around a vertical axis X32.
La plaque comprend en outre une vis 33 ; elle se visse dans un taraudage 34 formé dans une extrémité distale du verrou et passe au-travers d’un alésage 36 ajusté et formé dans une face transversale 42 du corps 30. Dans l’exemple illustré, la vis est une vis à tête cylindrique ayant une prise à six pans creux. Lorsque la vis traverse l’alésage 36 et est vissée dans le taraudage 34, elle maintient la plaque d’appui 3 dans une position fermée, notamment illustrée à la figure 1. Dans la position fermée, le verrou permet d’assurer une continuité de la face longitudinale 41 de la plaque d’appui. The plate further comprises a screw 33; it is screwed into a thread 34 formed in a distal end of the lock and passes through a bore 36 fitted and formed in a transverse face 42 of the body 30. In the example illustrated, the screw is a cylindrical head screw having a hexagonal socket socket. When the screw passes through the bore 36 and is screwed into the thread 34, it maintains the bearing plate 3 in a closed position, particularly illustrated in FIG. 1. In the closed position, the lock makes it possible to ensure continuity of the longitudinal face 41 of the bearing plate.
Dans la configuration de la figure 1, la plaque est montée fermée autour d’une portion libre 20A de la tige 20, axialement située entre la face inférieure 26 de la chape 21 et la face supérieure 27 du lardon 22 (voir figure 4). Dans la position fermée, le corps 30 et le verrou 31 forment ensemble un passage cylindrique 37 pour la portion libre 20A ; le passage et la portion forment ensemble une fonction pivot pour la broche 4 dans la plaque d’appui 3. Le corps et le verrou comprennent chacun une partie complémentaire respective 37A, 37B du passage 37. In the configuration of Figure 1, the plate is mounted closed around a free portion 20A of the rod 20, axially located between the lower face 26 of the yoke 21 and the upper face 27 of the gib 22 (see Figure 4). In the closed position, the body 30 and the lock 31 together form a cylindrical passage 37 for the free portion 20A; the passage and the portion together form a pivot function for the pin 4 in the support plate 3. The body and the lock each comprise a respective complementary part 37A, 37B of the passage 37.
Dans une position ouverte, la plaque permet d’introduire au travers de la face longitudinale 41 ainsi ouverte, transversalement à l’axe de tige X20, la portion 20A dans le passage 37A contre la partie 37A. In an open position, the plate makes it possible to introduce through the longitudinal face 41 thus opened, transversely to the stem axis X20, the portion 20A in the passage 37A against the part 37A.
La plaque 3 comprend en outre un pion 38 qui s’étend depuis la face transversaleThe plate 3 further comprises a pin 38 which extends from the transverse face
42 et perpendiculairement à cette face 42. Dans la position d’usage illustré aux figures, le pion 38 pénètre le trou poire 14, il permet de limiter le débattement latéral du dispositif 1. Dans cette position, la tête de la vis 33 est aisément accessible et la vis peut être vissée ou dévissée, au travers du trou poire, à l’aide d’une clef Allen. 42 and perpendicular to this face 42. In the position of use illustrated in figures, the pin 38 penetrates the pear hole 14, it makes it possible to limit the lateral displacement of the device 1. In this position, the head of the screw 33 is easily accessible and the screw can be screwed or unscrewed, through the pear hole, using an Allen key.
On note que la distance E4 entre les faces en vis-à-vis 26 et 27 est sensiblement égale à la somme de l’épaisseur El i de la paroi supérieure 11 du coin 6 et de l’épaisseur E3 de la plaque d’appui 3, avec un jeu suffisant pour permettre de prendre en compte les tolérances de fabrication du dispositif 1 et des aléas dimensionnels du coin 6. Cette disposition permet d’avoir un appui optimal de la plaque 3 contre la paroi supérieure 11 du coin, évitant notamment des risques de déformations, notamment un risque de poinçonnement du coin. It is noted that the distance E4 between the facing faces 26 and 27 is substantially equal to the sum of the thickness El i of the upper wall 11 of the corner 6 and the thickness E3 of the support plate 3, with sufficient clearance to allow the manufacturing tolerances of the device 1 and the dimensional variations of the corner 6 to be taken into account. deformations, in particular a risk of punching the corner.
Le lardon, en prenant appui contre la face inférieure 29 de la plaque d’appui, tend à en plaquer la face supérieure 28 contre la paroi supérieure 11 du coin 6. Ainsi, l’axe de tige XI lest maintenu dans une position sensiblement verticale, dans laquelle la broche peut s’orienter sensiblement librement autour de l’axe de tige X20, sous l’action d’une élingue qui y est fixée, du fait de l’écart E23 entre le trou de manille 23 et l’axe de tige X20, sans risque d’arcboutement de la tige 20 dans le passage 37. The gib, bearing against the lower face 29 of the support plate, tends to press the upper face 28 against the upper wall 11 of the wedge 6. Thus, the rod axis XI is maintained in a substantially vertical position, in which the pin can move substantially freely around the rod axis X20, under the action of a sling which is fixed there, due to the gap E23 between the shackle hole 23 and the rod axis X20, without risk of buttressing of rod 20 in passage 37.
Comme illustré en pointillés à la figure 4, la broche 4 peut aussi comprendre un talon 44 qui s’étend radialement depuis la base de la tige, dans une direction opposée à la direction D4, dans le prolongement du lardon 22. Ce talon permet de maintenir une position optimale du dispositif, même lorsque l’élingue exerce une action dont une composante horizontale dans la direction opposée à la direction D4. Ainsi, la broche peut pivoter de 180 degrés, naturellement, de façon à aligner la chape 21 avec l’élingue. As illustrated in dotted lines in Figure 4, the pin 4 may also include a heel 44 which extends radially from the base of the rod, in a direction opposite to the direction D4, in the extension of the gib 22. This heel makes it possible to maintain an optimal position of the device, even when the sling exerts an action including a horizontal component in the direction opposite to the direction D4. This allows the pin to rotate 180 degrees, of course, to align the clevis 21 with the sling.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits.Of course, the invention is not limited to the examples which have just been described.
Au contraire, l'invention est définie par les revendications qui suivent. Il apparaîtra en effet à l'homme de l'art que diverses modifications peuvent être apportées aux modes de réalisation décrits ci-dessus, à la lumière de l'enseignement qui vient de lui être divulgué. Ainsi, la plaque d’appui peut avoir une forme circulaire au lieu d’une forme rectangulaire ; notamment dans ce cas, le verrou peut avoir une forme annulaire mobile en rotation autour de l’axe de tige entre une position ouverte et une position fermée. Un dispositif présente aussi l’avantage de pouvoir y fixer des élinguettes et de les laisser pendre le long des parois du conteneur, ce qui facilite l’accrochage des élingues de levage, tout en étant assuré que le dispositif se positionnera correctement, lorsque les élinguettes seront mises en tension. On the contrary, the invention is defined by the following claims. It will indeed appear to those skilled in the art that various modifications can be made to the embodiments described above, in the light of the teaching which has just been disclosed to them. Thus, the support plate can have a circular shape instead of a rectangular shape; in particular in this case, the lock may have an annular shape that can rotate around the rod axis between an open position and a closed position. A device also has the advantage of being able to attach slings to it and let them hang along the walls of the container, which facilitates the attachment of the lifting slings, while being assured that the device will position itself correctly, when the slings are tensioned.
