Description

Perfectionnements aux dispositifs à câble pour la manutention des ôtes et plaques métalliques analogues. La présente invention est relative à des perfec tionnements apportés aux dispositifs à câble utilisés pour la manutention des tôles et plaques métalliques analogues, et elle vise à permettre la réalisation d'un dispositif du genre en question de construc tion simple, d'emploi particulièrement aisé et de sécurité par rapport aux dispositifs classiques. Improvements to cable devices for the handling of ribs and similar metal plates. The present invention relates to improvements made to the cable devices used for the handling of sheets and analogous metal plates, and it aims at enabling the realization of a device of the type in question of simple construction, particularly easy to use. and safety compared to conventional devices.

Le dispositif suivant l'invention est principalement remarquable en ce que chacune des extrémités du câble de manutention, rendu solidaire par sa partie médiane du crochet usuel de l'engin de levage est as sociée à une ;pince constituée par un profilé en forme de C ouvert latéralement, l'aile supérieure dudit profilé étant traversée à coulissement par la tige d'un poussoir dont le sommet porte une poulie d'actionnement propre à coopérer avec un brin de ce câble compris entre le point d'attache de l'extré mité de celui-ci sur le profilé et un galet de renvoi, le tout de manière à ce que l'effort de traction qui s'exerce sur<B>le</B> câble lors du levage de la charge engagée entre les deux pinces provoque l'abaisse ment automatique du poussoir précité et son appli cation sur ladite charge. The device according to the invention is mainly remarkable in that each end of the handling cable, secured by its middle part of the usual hook of the hoist is associated with a clamp constituted by a C-shaped profile. laterally open, the upper flange of said section being slidably traversed by the rod of a pusher whose top carries an actuating pulley adapted to cooperate with a strand of this cable between the point of attachment of the end of the latter on the profile and a return roller, all so that the tensile force exerted on the <B> the </ B> cable when lifting the load engaged between the two clamps causes the automatic lowering of the aforementioned pusher and its application on said load.

On prévoit avantageusement des moyens élasti ques propres à rappeler le poussoir vers le haut lorsque la tension du câble cesse de façon à per mettre la libération des tôles ou plaques engagées dans les pinces. Ces moyens élastiques peuvent être très simplement constitués par un ressort qui en toure la tige de coulissement du poussoir entre l'aile supérieure de chaque profilé ou pince et la face inférieure de la chape associée à la poulie d'actionnement du poussoir. Advantageously, resilient means are provided for biasing the pusher upwards when the cable tension ceases so as to allow the release of the plates or plates engaged in the clamps. These elastic means may be very simply constituted by a spring which rotates the sliding rod of the pusher between the upper flange of each profile or clamp and the underside of the yoke associated with the actuating pulley of the pusher.

Le dessin annexé, donné à titre d'exemple, per mettra de mieux comprendre l'invention, les ca ractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer. The accompanying drawing, given by way of example, will provide a better understanding of the invention, the features it presents and the advantages it is likely to provide.

Figure 1 est une vue schématique en élévation d'un dispositif de manutention suivant l'invention. Figure 2 est une vue de détail de l'une des pinces latérales du dispositif de figure 1. Figure 1 is a schematic elevational view of a handling device according to the invention. Figure 2 is a detail view of one of the side clamps of the device of Figure 1.

Figures 3 à 5 illustrant schématiquement trois variantes de réalisation. Figures 3 to 5 schematically illustrating three variants.

En figure 1, on a représenté en 1 un câble soli daire dans sa partie médiane d'une boucle ou oeil- let 2 engagé sur le crochet 3 d'un engin de levage quelconque (pont roulant, portique, grue, etc.). Les extrémités de ce câble 1 sont associées à deux pinces 4, chacune de ces pinces étant montrée à plus grande échelle en figure 2. In Figure 1, there is shown in 1 a solid cable in its middle part of a loop or eyelet 2 engaged on the hook 3 of any hoist (crane, gantry, crane, etc.). The ends of this cable 1 are associated with two clamps 4, each of these clamps being shown on a larger scale in FIG.

Chaque pince 4 est constituée par un profil (au quel on a affecté la référence 4) à profil en forme de C ouvert latéralement, les profilés des deux pinces s'ouvrant en direction l'un de l'autre. L'aile supérieure de ce profilé 4 est solidaire en bout d'un anneau 5 formant point d'attache pour l'extré mité correspondante du câble 1. Dans sa partie médiane l'aile supérieure est perforée transversa lement en 4a de manière à permettre l'engagement et le coulissement d'une tige verticale 6 dont l'ex trémité inférieure est solidaire, par vissage ou sou dure, d'une plaque d'appui 7 de tout profil désiré, disposée à l'intérieur du profilé 4; l'ensemble 6-7 ainsi constitué est destiné à former poussoir de retenue, ainsi qu'il sera expliqué en détail ci-après. Each clamp 4 is constituted by a profile (to which the reference 4 has been assigned) C-profile open laterally, the profiles of the two clamps opening in the direction of one another. The upper flange of this profile 4 is secured at the end of a ring 5 forming an attachment point for the corresponding end of the cable 1. In its middle part the upper flange is transversely perforated at 4a so as to allow the engagement and sliding of a vertical rod 6 whose lower end is secured, by screwing or hard, a support plate 7 of any desired profile, disposed within the section 4; the assembly 6-7 thus formed is intended to form retaining pusher, as will be explained in detail below.

L'extrémité supérieure libre de la tige 6 porte une chape 8 à l'intérieur de laquelle est montée à rotation une poulie d'actionnement 9; entre le voile central de la chape 8 et la paroi de l'aile supé rieure du profilé 4 ést prévu un ressort de rappel 10 engagé sur la tige 6 de manière à repousser l'ensemble 6-7-8-9 vers le haut. A l'opposé de l'an neau 5 l'aile supérieure précitée est solidaire d'une chape fixe 11, formant support pour une poulie ou galet de renvoi 12. On comprend que l'extrémité considérée du câble 1 peut être passée sous ce galet 12, puis sur la poulie d'actionnement 9 pour ar river à Vanneau 5 auquel elle est amarrée, le ira- jet de ladite extrémité déterminant ainsi un triangle isocèle dont le sommet est constitué par la poulie 9 associée au poussoir 6-7. The upper free end of the rod 6 carries a yoke 8 inside which is rotatably mounted an actuating pulley 9; between the central web of the yoke 8 and the wall of the upper flange of the profile 4 is provided a return spring 10 engaged on the rod 6 so as to push the assembly 6-7-8-9 upwards. Opposite the ring 5 the aforementioned upper wing is secured to a fixed yoke 11, forming a support for a pulley or return roller 12. It is understood that the considered end of the cable 1 can be passed under this roller 12, then on the actuating pulley 9 for ar river to the ring 5 to which it is moored, the irajet of said end thus determining an isosceles triangle whose apex is constituted by the pulley 9 associated with the pusher 6-7.

Il est facile de constater que dans ces condi tions tout effort exercé sur le câble 1 tend à re pousser vers le bas la poulie 9 et le poussoir 6-7 de chaque pince 4, et ce à l'encontre du ressort de rappel 10 associé audit poussoir. Pour l'utili sation du dispositif suivant l'invention, il suffit donc d'engager dans les profilés ou pinces 4 les bords transversaux de l'empilage de tôles 13 destiné à être déplacé et de manceuvrer l'engin de levage de façon à opérer l'élévation du crochet 3. L'effort ainsi exercé sur le câble 1 provoque -l'abaisse ment des poussoirs 6-7 des pinces 1, la butée 7 s'appliquant alors contre la face supérieure de l'empilage 13 et assurant en conséquence le maintien ferme dudit empilage (fig. 1). Dès que le câble 1 est détendu pour la dépose des tôles, les ressorts 10 ramènent les poussoirs<B>6-7</B> à la po sition haute. It is easy to note that under these conditions any force exerted on the cable 1 tends to push down the pulley 9 and the pusher 6-7 of each clamp 4, and this against the associated return spring 10 pusher audit. For the use of the device according to the invention, it is therefore sufficient to engage in the profiles or clamps 4 the transverse edges of the stack of sheets 13 to be moved and to maneuver the lifting machine so as to operate the elevation of the hook 3. The force thus exerted on the cable 1 causes the lowering of the pushers 6-7 of the clamps 1, the stop 7 then applying against the upper face of the stack 13 and ensuring as a result the firm holding of said stack (Fig. 1). As soon as the cable 1 is relaxed for removing the sheets, the springs 10 bring the pushers <B> 6-7 </ B> to the high position.

Il va de soi que le dispositif suivant hinvention peut être agencé de manière à comprendre une pluralité de câbles 1, réunis par leur partie mé diane à une bouche 2 unique, chacun desdits câbles étant associé à deux pinces 4 du type précité. It goes without saying that the device according hinvention can be arranged to include a plurality of cables 1, joined by their median part to a single mouth 2, each of said cables being associated with two clamps 4 of the aforementioned type.

Il doit d'ailleurs être entendu que la description qui ,précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'in vention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équiva lents. On comprend notamment que l'anneau 5 peut en certains cas être fixé sur l'aile supérieure du profilé 4 immédiatement au droit du poussoir 6-7 (fig. 3) ; en variante (fig. 4) l'extrémité du câble 1 peut être directement amarrée en 5' au sommet de ce poussoir 6-7, ledit câble étant renvoyé vers la poulie 12 au moyen d'une seconde poulie 12' prévue entre ladite poulie 12 et la base du poussoir précité. Dans la forme de réalisation schématisée en figure 5, les deux extrémités du câble 1 sont associée à une pince unique constituée par un pro filé en forme de U ouvert vers le bas, chacune desdites extrémités coopérant avec un mécanisme à poussoir 6-7 du type susdécrit. Le dispositif peut alors être utilisé pour la manutention de tôles pin cées verticalement entre les deux poussoirs 6-7.It must also be understood that the description which precedes has been given only as an example and that it does not in any way limit the field of the invention of which we would not go out by replacing the details of execution described by all other equiva lents. It is understood in particular that the ring 5 may in certain cases be fixed on the upper flange of the profile 4 immediately to the right of the pusher 6-7 (Figure 3); alternatively (FIG 4) the end of the cable 1 can be directly moored 5 'to the top of this pusher 6-7, said cable being returned to the pulley 12 by means of a second pulley 12' provided between said pulley 12 and the base of the aforementioned pusher. In the embodiment shown diagrammatically in FIG. 5, the two ends of the cable 1 are associated with a single clip constituted by a downwardly open U-shaped profile, each of said ends cooperating with a push mechanism 6-7 of the type shown in FIG. above described. The device can then be used for the handling of pine sheets vertically between the two pushers 6-7.
