Description
On connaît de nombreux moyens en vue de fixer un câble à un tambour de câble. Toutefois, bon nombre de ces constructions donnent lieu à des difficultés dont on donnera ici un bref résumé.Numerous means are known for attaching a cable to a cable drum. However, many of these constructions give rise to difficulties of which a brief summary will be given here.
Si l'on fait passer le câble à travers une ouverture pratiquée dans le flasque du tambour au niveau du tube comme révélé par exemple dans le brevet français n° 53.418, et si on fixe ce câble à l'autre côté de ce dernier au moyen d'une pince, il en résulte des défaillances dans l'assemblage du flasque au tube du tambour, si bien que l'on doit adapter un renforcement autour de cette ouverture et sur la face où se trouve la pince à câble. De plus, principalement dans le cas de câble de grand diamètre, cette solution donne lieu à des difficultés lorsqu'il s'agit de faire passer le câble à travers le flasque du tambour.If the cable is passed through an opening made in the flange of the drum at the level of the tube as revealed for example in French patent n ° 53.418, and if this cable is fixed to the other side of the latter by means of a clamp, this results in failures in the assembly of the flange to the drum tube, so that a reinforcement must be adapted around this opening and on the face where the cable clamp is located. In addition, mainly in the case of large diameter cable, this solution gives rise to difficulties when it comes to passing the cable through the flange of the drum.
Les difficultés mentionnées ci-dessus se rencontrent également dans les dispositifs dans lesquels le câble passe à travers une ouverture pratiquée dans la paroi du tambour comme cela est illustré par exemple dans le brevet américain n° 1.913.508.The difficulties mentioned above are also encountered in devices in which the cable passes through an opening made in the wall of the drum as is illustrated, for example, in US Patent No. 1,913,508.
Si l'on abandonne ce principe et si l'on fixe le câble au tambour au moyen d'un crochet pourvu d'un bout de boulon avec écrou entourant le câble, lors de l'enroulement de ce dernier, il se crée un obstacle local que l'on retrouve dans toutes les couches enroulées et qui peut donner lieu à d'importantes difficultés pour le mécanisme de guidage du câble dans le tambour à câble envisagé.If this principle is abandoned and the cable is fixed to the drum by means of a hook provided with a bolt end with nut surrounding the cable, when the latter is wound up, an obstacle is created local found in all coiled layers and which can give rise to significant difficulties for the cable guide mechanism in the cable drum envisaged.
On doit noter que ces difficultés relatives au guidage existent aussi bien lorsque le crochet passe par une ouverture du tambour comme illustré par le brevet américain n° 2.358.580, que lorsqu'il passe par une ouverture du flasque (voir le brevet américain n° 2.420.594) ou du flasque et du tambour, comme illustré par le brevet américain n° 2.421.788.It should be noted that these difficulties relating to guiding exist as well when the hook passes through an opening of the drum as illustrated by American patent n ° 2,358,580, as when it goes through an opening of the flange (see American patent n ° 2,420,594) or of the flange and of the drum, as illustrated by the American patent n ° 2,421,788.
Enfin, dans le brevet allemand n° 1.245.560, on décrit un dispositif de fixation d'un câble sur un tambour de treuil comprenant un block 3 de fixation du câble fixé sur le flasque latéral 1 du tambour 6 de manière à ce que l'extrémité du câble parte tangentiellement au tambour 6, comme on peut le voir à la figure 2 de ce brevet, le bloc 3 est disposé dans une cage spécialement aménagée dans la paroi interne du flasque 1.Finally, in German patent No. 1,245,560, a device for fixing a cable to a winch drum is described comprising a
Cette disposition n'est pas très satisfaisante puiqu'il faut réaliser des flasques spéciaux et en outre la fixation de l'extrémité du câble dans un tel bloc n'est pas aisée à réaliser comme cela peut ressortir de la lecture de ce brevet.This arrangement is not very satisfactory since special flanges have to be made and furthermore the fixing of the end of the cable in such a block is not easy to carry out as can be seen from reading this patent.
La présente invention a non seulement pour but de réaliser une construction simple, mais d'éviter les inconvénients résumés ci-dessus.The present invention not only aims to achieve a simple construction, but to avoid the drawbacks summarized above.
A cet effet, dans un bloc carré ou analogues, dont la face a les mêmes dimensions que le diamètre du câble à fixer, on pratique une encoche longitudinale un peu plus large que le diamètre d'un brin du câble. Le câble qui est ligaturé à son extrémité et dont un ou plusieurs brins passent avec une longueur à peu près égale à celle de la pince à câble est serré entre le tube du tambour et le bloc précité au moyen de vis à pression noyées. Cette pince est à son tour soudée au tube et au flasque du tambour, réalisant ainsi un assemblage ferme entre le câble et le tambour.To this end, in a square block or the like, the face of which has the same dimensions as the diameter of the cable to be fixed, a longitudinal notch is made a little wider than the diameter of a strand of the cable. The cable which is tied at its end and one or more strands of which pass with a length approximately equal to that of the cable clamp is clamped between the drum tube and the aforementioned block by means of countersunk pressure screws. This clamp is in turn welded to the tube and the flange of the drum, thereby achieving a firm connection between the cable and the drum.
Etant donné que, vu en coupe transversale, les dimensions de la pince sont à peu près égales au diamètre du câble, il ne se produit aucun défaut lors de l'enroulement car, pour des câbles de grand diamètre, on peut en outre éventuellement placer, derrière la pince à câble, une clavette remplissant l'espace mort formé à la transition entre la première et la deuxième gaine du câble au niveau de la pince. En outre, la présente invention offre un avantage non négligeable du fait qu'aucun obstacle n'intervient dans le montage du tambour de câble, puisqu'aussi bien on ne prévoit aucune traversée de câble ni dans le tube du tambour, ni dans son flasque.Since, seen in cross section, the dimensions of the clamp are roughly equal to the diameter of the cable, there is no defect during winding because, for cables of large diameter, it is also possible to place , behind the cable clamp, a key filling the dead space formed at the transition between the first and second sheath of the cable at the clamp. In addition, the present invention offers a non-negligible advantage in that no obstacle intervenes in the mounting of the cable drum, since as well no cable crossing is foreseen either in the drum tube or in its flange .
Afin d'illustrer davantage ce procédé, on se référera aux dessins annexés donnés purement et simplement à titre d'information et ne limitant dès lors nullement la description de la présente invention.In order to illustrate this process further, reference will be made to the appended drawings given purely and simply for information and therefore in no way limiting the description of the present invention.
La figure 1 est une coupe transversale de la pince à câble suivant l'invention avec un brin, cette coupe étant prise suivant la ligne 1-1 de la figure 2; la figure 2 est une vue partielle par le sommet de la pince avec le câble.Figure 1 is a cross section of the cable clamp according to the invention with a strand, this section being taken along line 1-1 of Figure 2; Figure 2 is a partial view from the top of the clamp with the cable.
Le chiffre de référence 1 désigne le flasque du tambour qui est assemblé au tube 2 de ce dernier de façon connue. Dans la pince 3 à section carrée ou analogues dont la face a à peu près les mêmes dimensions que le diamètre du câble 6, est pratiquée une encoche de largeur A un peu plus grande que le diamètre du brin 5 ayant à peu près une longueur égale à la dimension B de la pince à câble. A son tour, la pince à câble 3 est assemblée au flasque 1 et au tube 2 du tambour au moyen des points de soudure 7 et 7'. Au moyen des vis à pression 4 noyées dans la pince 3 et la plaquette de protection 8, le brin 5 du câble 6 est serré entre la pince à câble 3 et le tube 2 du tambour de câble, assurant ainsi un assemblage ferme entre le câble 6 et le tambour. La clavette 9de même hauteur que la pince à câble peut, dans le cas de câbles de grand diamètre, être placée derrière la pince 3 afin de neutraliser l'espace mort entre la première et la deuxième gaine du câble.The
La pince à câble décrite ci-dessus est d'une construction très simple et exige un minimum d'opérations.The cable clamp described above is of a very simple construction and requires a minimum of operations.
