Abstract

The coupling device has a sleeve of a shrink-fit material used to enclose at least part of the hydraulic hose or electrical cable connection, formed using standard connection components, for protecting it from the effects of the weather to prevent corrosion. Pref. the sleeve is made from a material which shrinks upon application of heat, e.g. provided by a hot air stream and has an adhesive layer on its inside face, for secure adhesion to the connection point.

Description

L'invention conceme un dispositif pour l'accouplement de conducteurs, tels que les tuyaux hydrauliques, les fils électriques et semblables, où l'on se sert d'accouplements standards, comme des émerillons, des fiches et semblables. The invention relates to a device for coupling conductors, such as hydraulic hoses, electric wires and the like, where standard couplings are used, such as swivels, plugs and the like.

L'accouplement de conducteurs est d'usage courant dans les domaines techniques, où se pose le problème de protéger ces accouplements contre les influences du temps et des produits agressifs, par exemple les produits chimiques, comme les engrais artificiels, afin de prévenir la corrosion et de faciliter de démontage ultérieur. Des propositions différentes ont été faites pour effectuer cette protection, soit on se sert de matières de base coûteuses, qui résistent à la rouille, soit on protège ces accouplements postérieurement par une couche protectrice. Coupling of conductors is in common use in technical fields, where the problem arises of protecting these couplings against the influences of time and aggressive products, for example chemicals, such as artificial fertilizers, in order to prevent corrosion. and facilitate subsequent disassembly. Different proposals have been made to provide this protection, either using expensive base materials which resist rust, or these couplings are subsequently protected by a protective layer.

Cette couche peut être par exemple une couche de peinture, de chrome ou de zinc.This layer can be for example a layer of paint, chromium or zinc.

L'entretien de tels accouplements dans le domaine des engins agricoles, spécialement ceux qui sont sujets à une corrosion violente, pose néanmoins des problèmes concernant les couches appliquées postérieurement qui, endommagées, permettent la corrosion des accouplements. L'invention vise à résoudre ces problèmes et procure à cette fin un dispositif qui se distingue en ce qu'une chemise en un matériau rétrécissable est appliquée autour d'au moins une partie de la jonction, afin de protéger l'accouplement contre les influences du temps et de la corrosion.The maintenance of such couplings in the field of agricultural machinery, especially those which are subject to violent corrosion, nevertheless poses problems concerning the layers applied subsequently which, damaged, allow corrosion of the couplings. The invention aims to solve these problems and provides for this purpose a device which is distinguished in that a jacket of shrinkable material is applied around at least part of the junction, in order to protect the coupling from influences. time and corrosion.

Selon l'invention, cette chemise est préférablement fabriquée dans un matériau qui se rétracte sous l'influence de la chaleur. Grâce au rétrécissement, la chemise se plaquera très étroitement contre l'accouplement, évitant ainsi toute détérioration, le cas échéant corrosion, par les intempéries où autres influences. According to the invention, this shirt is preferably made of a material which shrinks under the influence of heat. Thanks to the shrinkage, the jacket will be pressed very tightly against the coupling, thus avoiding any deterioration, if necessary corrosion, by bad weather or other influences.

Préférablement, la chemise rétrécissable est munie intérieurement d'une couche adhésive, par exemple de colle, grâce à quoi la protection résistera mieux aux vibrations. Preferably, the shrinkable shirt is internally provided with an adhesive layer, for example glue, thanks to which the protection will resist vibration better.

Ensuite, I'invention concerne une méthode pour l'accouplement réciproque de conducteurs, comme les tuyaux hydrauliques et semblables susmentionnés, où l'on se sert d'accouplements standards. Cette méthode se distingue en ce qu'une chemise de dimensions amples est glissée, avant le montage de l'accouplement, autour d'un conducteur à accoupler, qu'ensuite l'accouplement est réalisé, après quoi la chemise est appliquée autour de la pièce à protéger qui est ensuite chauffée, préférablement sous l'influence d'un courant d'air chaud, de sorte que le matériau va se rétracter et va se plaquer étroitement contre l'accouplement. Next, the invention relates to a method for the reciprocal coupling of conductors, such as the above-mentioned hydraulic hoses and the like, where standard couplings are used. This method is distinguished in that a jacket of large dimensions is slipped, before mounting the coupling, around a conductor to be coupled, after which the coupling is carried out, after which the jacket is applied around the part to be protected which is then heated, preferably under the influence of a current of hot air, so that the material will shrink and will be pressed tightly against the coupling.

Selon l'invention, la chemise rétrécissable est munie intérieurement d'une couche adhésive, avant le montage.  According to the invention, the shrinkable jacket is provided internally with an adhesive layer, before assembly.

L'invention sera élucidée ci-après à l'aide d'un exemple d'exécution, qui est représenté en perspective et de manière schématique sur le dessin ci-joint. The invention will be elucidated below using an embodiment, which is shown in perspective and schematically in the accompanying drawing.

La figure conceme une partie quelconque d'un engin agricole, dont le bâti est indiqué par G. Le long du bâti est installé un système de conduits hydrauliques, comportant une partie 1, une partie 3 et une partie 13, qui sont mutuellement fixées par les accouplements 2. L'accouplement est un té sur lequel chaque fois un émerillon 2' doit être vissé. Le té et les émerillons peuvent être fabriqués dans un matériau relativement peu coûteux, étant donné selon l'invention qu'avant la fixation des émerillons sur le té une chemise 12 est glissée sur les parties conductrices 1, 3 et 13. La chemise est de dimension large et se pose aisément sur les émerillons. The figure relates to any part of an agricultural machine, the frame of which is indicated by G. Along the frame is installed a system of hydraulic conduits, comprising a part 1, a part 3 and a part 13, which are mutually fixed by the couplings 2. The coupling is a tee on which each time a swivel 2 'must be screwed. The tee and the swivels can be made of a relatively inexpensive material, since according to the invention that before the fixing of the swivels on the tee a jacket 12 is slid over the conductive parts 1, 3 and 13. The shirt is large size and easy to install on swivels.

Après l'accouplement des émerillons au té, la chemise 12 est glissée à l'endroit voulu, ensuite rétractée par un courant d'air chaud produit par une soufflerie B, grâce à quoi la chemise se plaque étroitement contre les parties délicates de l'accouplement. Ainsi, une étanchéité totale contre les intempéries est effectuée. After coupling the swivels to the tee, the jacket 12 is slid to the desired location, then retracted by a current of hot air produced by a blower B, whereby the jacket is pressed tightly against the delicate parts of the coupling. Thus, a total seal against the weather is carried out.

Dans le cadre de l'invention, il sera évident que, dans l'exemple précité, les accouplements hydrauliques peuvent être remplacés simplement par d'autres conducteurs, comme des conducteurs électriques, où les conducteurs peuvent s'accoupler par des jonctions de fiches mâles et femelles. In the context of the invention, it will be obvious that, in the aforementioned example, the hydraulic couplings can be replaced simply by other conductors, such as electrical conductors, where the conductors can be coupled by plug connectors and females.

L'invention n'est pas limitée au formes d'exécution décrites ci-dessus.  The invention is not limited to the embodiments described above.
