Abstract

The invention relates to a device making it possible correctly to roll up, with contiguous turns and in one or more layers, a cable originating from a return pulley, over the entire length of a rolling-up drum. The device consists of a slide including an aperture through which the cable passes, moving from one end to the other of a ramp consisting of two curved slideways. The shape of this curve, which is symmetrical with respect to the axis of the drum, defines more or less great angles of friction of the slide, having the effect of braking it in its movement, when the cable is most likely naturally to position itself in the axis of the pulley and of the drum. The device according to the invention is intended particularly for making a cable guide for rolling on a drum.

Description

La présente invention concerne un dispositif simple permettant l'enroulement correct, spire contre spire, en une ou plusieurs couches, sur la totalité de la longueur d'un tambour d'enroulement d'un treuil (1), d'un câble (2) provenant d'une poulie de renvoi (3). The present invention relates to a simple device allowing the correct winding, turn to turn, in one or more layers, over the entire length of a winding drum of a winch (1), of a cable (2 ) from a return pulley (3).

L'inclinaison admissible du câble sur le tambour par rapport à la poulie de renvoi donnée par la norme ne suffit pas a avoir l'assurance d'un enroulement correct en spires bien serrées. The admissible inclination of the cable on the drum with respect to the return pulley given by the standard is not sufficient to have the assurance of a correct winding in tight turns.

Notamment lorque le câble ne peut s'appuyer sur la spire précédente. Ce qui est toujours le cas lorsque le câble s'enroule depuis un flasque(4) du tambour en allant vers l'axe (5) du tambour. Le câble a toujours tendance a se positionner le plus rapidement possible sur cet axe,ce qui provoque un grand écartement des spires jusqu'à cet axe, puis un enroulement correct au-delà, le câble s'appuyant sur la spire précédente jusqu'au flasque opposé du tambour. In particular when the cable cannot rest on the previous turn. This is always the case when the cable is wound from a flange (4) of the drum going towards the axis (5) of the drum. The cable always tends to position itself as quickly as possible on this axis, which causes a large spacing of the turns to this axis, then a correct winding beyond, the cable resting on the previous turn to opposite flange of the drum.

Le retour s'effectuant de la même façon, rapidement vers le centre.The return is made in the same way, quickly to the center.

Le dispositif selon l'invention permet de remédier à cet inconvénient en créant une retenue (6) du câble (2) équivalente a son besoin naturel d'aller vers le centre du tambour dans la phase d'enroulement depuis un des flasques du tambour (4) vers son axe (5) et le laisser libre dans la phase d'enroulement de l'axe vers le flasque opposé ; d'une façon alternative à chaque couche. The device according to the invention overcomes this drawback by creating a retainer (6) of the cable (2) equivalent to its natural need to go towards the center of the drum in the winding phase from one of the flanges of the drum ( 4) towards its axis (5) and leave it free in the winding phase of the axis towards the opposite flange; in an alternative way to each layer.

Selon une première caractéristique le dispositif est composé d'un coulisseau (7) comportant une lumière (8) de dimension égale à la hauteur des couches à enrouler, au travers de laquelle passe le câble (2) et d'une rampe courbe (9) constituée de deux glissières (10) convexes. L'ensemble sera positionné, en face et près de l'arrivée du câble sur le tambour et solidement fixé sur un élément fixe qui peut être le treuil lui-même. According to a first characteristic, the device is composed of a slide (7) comprising a light (8) of dimension equal to the height of the layers to be wound, through which the cable (2) passes and a curved ramp (9 ) consisting of two convex slides (10). The assembly will be positioned, opposite and near the arrival of the cable on the drum and solidly fixed on a fixed element which may be the winch itself.

Lors de l'enroulement du câble (2) sur le tambour (1), le câble exerce une poussée latérale (11) sur le coulisseau (7) qui va glisser sur la rampe (9) d'une extrémité à l'autre.  When winding the cable (2) on the drum (1), the cable exerts a lateral thrust (11) on the slide (7) which will slide on the ramp (9) from one end to the other.

Dans les extrémités cette rampe sera droite ou même incurvée (12) pour permettre au coulisseau de glisser librement afin que le câble se dégage aisément du flasque pour constituer la première spire de retour, puis le coulisseau abordera la courbure de la rampe, qui compte tenu de l'angle ainsi créé (13) se trouvera freiné (6) dans son glissement. Cet angle (13) sera le plus élevé pour la partie où le câble exerce la plus grande pression (11) c est-à-dire près des extrémités, et cet angle sera nul a proximité de l'axe du tambour (5) où le câble n'exerce plus de poussée. In the ends this ramp will be straight or even curved (12) to allow the slider to slide freely so that the cable is easily released from the flange to form the first return turn, then the slider will approach the curvature of the ramp, which taking into account of the angle thus created (13) will be braked (6) in its sliding. This angle (13) will be the highest for the part where the cable exerts the greatest pressure (11) that is to say near the ends, and this angle will be zero near the axis of the drum (5) where the cable no longer pushes.

La courbure ainsi obtenue étant symétrique le phénomène de retenue du coulisseau s'exercera alternativement d'un flasque vers le centre du tambour dans un sens ou dans l'autre. The curvature thus obtained being symmetrical the phenomenon of retention of the slide will be exerted alternately from a flange towards the center of the drum in one direction or the other.

Le dimensionnement des éléments de ce dispositif seront fonction du diamètre du câble à enrouler et de la longueur du tambour. The dimensioning of the elements of this device will depend on the diameter of the cable to be wound and the length of the drum.

Selon des variantes le coulisseau pourrait êtré équipé de tout système permettant son glissement aisé et il pourrait être doté d'une pièce d'usure amovible et éventuellement orientable, comportant la lumière de passage du câble. According to variants, the slide could be equipped with any system allowing its easy sliding and it could be provided with a removable and possibly orientable wearing part, comprising the cable passage light.

Le dispositif selon l'invention est particulièrement destiné à faire un guide-câble d'enroulement sur tambour.  The device according to the invention is particularly intended for making a cable guide for winding on a drum.
