Description

La présente invention concerne une bobine pour le stockage et le transport de matériaux souples tels que des câbles de transport d'énergie électrique, des cordes, des tuyaux souples ou similaires, comportant deux joues latérales circulaires reliées entre elles par un tambour cylindrique réalisé au moyen de segments juxtaposés portés par deux supports circulaires solidaires desdites joues latérales.The present invention relates to a reel for storing and transporting flexible materials such as cables for transporting electrical energy, ropes, flexible pipes or the like, comprising two circular lateral cheeks connected together by a cylindrical drum produced by means juxtaposed segments carried by two circular supports integral with said side cheeks.

On connaît déjà des bobines ou tourets de câbles comportant des joues latérales et un tambour central métallique. On connaît également des bobines dont les joues et les tambours sont entièrement en bois éventuellement cerclés de fer. Pour différentes raisons il peut être utile de réaliser des tourets ayant des joues latérales métalliques et un tambour central en bois. L'un des problèmes posés par cette réalisation est l'échange ou la réparation rapide des planchettes juxtaposées formant la surface circonférentielle du tambour cylindrique.Coils or cable drums are already known comprising lateral cheeks and a central metallic drum. Coils are also known whose cheeks and drums are entirely made of wood, possibly surrounded by iron. For various reasons it may be useful to make drums having metal side cheeks and a central wooden drum. One of the problems posed by this embodiment is the rapid exchange or repair of the juxtaposed boards forming the circumferential surface of the cylindrical drum.

Dans une construction de ce genre selon le brevet US NQ 2 977 066, chaque segment en bois du tambour comporte à chaque extrémité un tenon engagé dans une rainure radiale de la joue correspondante, de sorte que le segment est mis en place par insertion en direction radiale entre les joues. Les segments s'appuient contre un cercle intérieur de chaque joue et sont maintenus ensemble au moyen de deux bandes de feuillard qui encerclent le tambour. Pour chan- gerun segment, il faut couper ces bandes, si bien que les autres segments risquent de tomber si on ne les retient pas par un autre moyen. En outre, la présence des rainures radiales empêche les joues de présenter une surface lisse du côté du câble.In a construction of this kind according to US patent NQ 2 977 066, each wooden segment of the drum has at each end a tenon engaged in a radial groove of the corresponding cheek, so that the segment is put in place by insertion in the direction radial between the cheeks. The segments are pressed against an inner circle of each cheek and are held together by means of two strips of strip which encircle the drum. To change a segment, these strips must be cut, so that the other segments may fall if they are not retained by some other means. In addition, the presence of the radial grooves prevents the cheeks from having a smooth surface on the side of the cable.

La demande de brevet FR-A-2 436 740 décrit une bobine pour câbles où les joues latérales se composent d'éléments modulaires en tôle emboutie qui définissent ensemble une rainure annulaire pour l'emboîtement des extrémités des segments en bois du tambour. Pour pouvoir remplacer l'un de ces segments, il faut enlever l'une des joues ou démonter partiellement cette joue.Patent application FR-A-2 436 740 describes a cable reel where the side flanges consist of modular elements made of stamped sheet metal which together define an annular groove for interlocking the ends of the wooden segments of the drum. To be able to replace one of these segments, you must remove one of the cheeks or partially disassemble this cheek.

La présente invention se propose d'apporter une solution aux problèmes évoqués ci-dessous, en réalisant une bobine dans laquelle le tambour comporte un ensemble de segments juxtaposés, qui peuvent être des planchettes en bois, des éléments métalliques profilés, des éléments en matière synthétique ou similaire, et qui sont facilement accessibles, notamment lors du montage de la bobine et lorsqu'il faut remplacer un ou plusieurs segments du tambour.The present invention proposes to provide a solution to the problems mentioned below, by producing a coil in which the drum comprises a set of juxtaposed segments, which can be wooden boards, profiled metal elements, elements made of synthetic material. or similar, and which are easily accessible, in particular during assembly of the coil and when it is necessary to replace one or more segments of the drum.

Dans ce but, la bobine selon l'invention est caractérisée en ce que lesdits supports circulaires comportent deux cercles coaxiaux ménageant entre eux un espace annulaire dont la hauteur est sensiblement égale à l'épaisseur des segments juxtaposés et qui est agencé pour permettre l'insertion latérale desdits segments.For this purpose, the coil according to the invention is characterized in that said circular supports comprise two coaxial circles forming between them an annular space whose height is substantially equal to the thickness of the juxtaposed segments and which is arranged to allow insertion lateral of said segments.

Dans la forme de réalisation préférée, cette bobine comporte des éléments de fermeture de l'espace annulaire et de maintien en place desdits segments juxtaposés.In the preferred embodiment, this coil comprises elements for closing the annular space and for holding in place said juxtaposed segments.

D'une façon avantageuse, elle peut comporter au moins trois entretoises rigides pour maintenir les joues latérales parallèles entre elles, et les segments juxtaposés ont sensiblement la même longueur que lesdites entretoises.Advantageously, it can comprise at least three rigid spacers to maintain the lateral cheeks parallel to one another, and the juxtaposed segments have substantially the same length as said spacers.

De préférence, les éléments de fermeture sont constitués par des secteurs annulaires dont la hauteur est sensiblement égale à celle de l'espace annulaire et ces secteurs annulaires sont disposés entre deux entretoises rigides et fixés à ces dernières par des moyens de fixation rapide.Preferably, the closure elements are constituted by annular sectors whose height is substantially equal to that of the annular space and these annular sectors are arranged between two rigid spacers and fixed to the latter by rapid fixing means.

Le cercle intérieur desdits cercles coaxiaux est avantageusement relié à au moins un croisillon qui porte une extrémité de l'axe central de la bobine.The inner circle of said coaxial circles is advantageously connected to at least one spider which carries one end of the central axis of the coil.

Dans la forme de réalisation décrite, les joues latérales comportent un élément annulaire extérieur et un élément circulaire central coaxial audit élément annulaire extérieur et l'espace annulaire est ménagé entre ledit élément annulaire extérieur et ledit élément circulaire central.In the embodiment described, the lateral cheeks have an external annular element and a central circular element coaxial with said external annular element and the annular space is formed between said external annular element and said central circular element.

La présente invention sera mieux comprise en référence à la description d'une forme de réalisation préférée et au dessin annexé dans lequel :

  • - la figure 1 est une vue en perspective d'une forme de réalisation préférée de la bobine selon l'invention,
  • - la figure 2 est une vue frontale en élévation de la bobine selon la figure 1, et
  • - la figure 3 est une vue partiellement coupée d'une moitié de la bobine des figures 1 et 2.
The present invention will be better understood with reference to the description of a preferred embodiment and to the accompanying drawing in which:
  • FIG. 1 is a perspective view of a preferred embodiment of the coil according to the invention,
  • FIG. 2 is a front elevation view of the coil according to FIG. 1, and
  • FIG. 3 is a partially cut view of one half of the coil of FIGS. 1 and 2.

En référence aux figures, la bobine 10 représentée comporte deux joues latérales 11 et un tambour central 12. Chaque joue latérale se compose d'un élément annulaire extérieur 13 et d'un élément circulaire central 14. Entre ces deux éléments coaxiaux est ménagé un espace annulaire 15. L'élément annulaire extérieur 13 se compose par exemple d'un cercle extérieur en fer plat ou profilé 16, d'un cercle intérieur en fer plat ou profilé 17 et d'une structure de liaison 18 qui remplit en totalité ou en partie l'espace entre le cercle intérieur et le cercle extérieur. Cette structure de liaison peut être réalisée au moyen de plaques de tôle lisse ou plissée, d'éléments profilés en forme de secteurs annulaires en métal, en bois, en matière synthétique, en matériaux composites, etc. L'élément circulaire intérieur 14 se compose par exemple d'un cercle périphérique 19 et de deux croisillons 20, assemblés en croix et disposés sur deux diamètres perpendiculaires du cercle périphérique 19. Les croisillons 20 des deux joues latérales 11 portent l'axe central 21 de la bobine.With reference to the figures, the coil 10 shown has two side cheeks 11 and a central drum 12. Each side cheek consists of an outer annular element 13 and a central circular element 14. Between these two coaxial elements is provided a space annular 15. The outer annular element 13 consists for example of an outer circle of flat or profiled iron 16, an inner circle of flat or profiled iron 17 and of a connecting structure 18 which completely or completely fills part of the space between the inner circle and the outer circle. This connecting structure can be produced by means of smooth or pleated sheet metal plates, profiled elements in the form of annular sectors of metal, wood, synthetic material, composite materials, etc. The inner circular element 14 consists for example of a peripheral circle 19 and two cross-pieces 20, assembled in a cross and arranged on two diameters perpendicular to the peripheral circle 19. The cross-pieces 20 of the two lateral cheeks 11 carry the central axis 21 of the coil.

Le tambour central 12 comporte quatre entretoises 22 qui sont montées entre les deux joues latérales 11 de manière à les maintenir parallèles entre elles et à les lier rigidement. Ces entretoises sont engagées à leurs extrémités opposées dans les espaces annulaires 15 définis entre les cercles intérieurs 17 des éléments annulaires extérieurs 13 et les cercles périphériques 19 des éléments circulaires centraux 14 des joues latérales. Lesdits cercles intérieurs 17 et lesdits cercles périphériques 19 sont fixés aux entretoises 22 et constituent en fait des supports circulaires dans lesquels on engage des segments 23 qui sont juxtaposés de manière à constituer la surface circonférentielle du tambour cylindrique 12. Ces segments peuvent être en bois, en métal, en matière synthétique ou similaire et se présenter approximativement comme des douves de tonneau. Ils sont conçus pour pouvoir être insérés axialement à travers l'espace annulaire 15 de l'une et/ou de l'autre desdites joues latérales entre les quatre entretoises 22. Pour les maintenir en place on engage ensuite des secteurs annulaires 24, dont l'angle d'ouverture est par exemple de 90°, entre les cercles 17 et 19 ou sur ceux-ci et l'on fixe les secteurs 24 aux entretoises 22 par des moyens de fixation rapide, par exemple des vis 25.The central drum 12 has four spacers 22 which are mounted between the two side cheeks 11 so as to keep them parallel to one another and to rigidly link them. These spacers are engaged at their opposite ends in the annular spaces 15 defined between the inner circles 17 of the outer annular elements 13 and the peripheral circles 19 of the central circular elements 14 of the lateral cheeks. Said inner circles 17 and said peripheral circles 19 are fixed to the spacers 22 and in fact constitute circular supports in which segments 23 are engaged which are juxtaposed so as to constitute the circumferential surface of the cylindrical drum 12. These segments can be made of wood, made of metal, synthetic material or the like and appear approximately as barrel staves. They are designed so that they can be inserted axially through the annular space 15 of one and / or the other of said lateral cheeks between the four spacers 22. To keep them in place, then annular sectors 24 are engaged, the l the opening angle is for example 90 °, between the circles 17 and 19 or thereon and the sectors 24 are fixed to the spacers 22 by quick fixing means, for example screws 25.

L'avantage de cette construction réside dans le fait que le tambour peut être réparé très rapidement par remplacement d'un, de plusieurs ou de la totalité des segments qui le composent.The advantage of this construction lies in the fact that the drum can be repaired very quickly by replacing one, several or all of the segments which compose it.

La présente invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus, mais elle s'étend à toute modification ou variante évidente pour un homme de l'art. En particulier, il est bien entendu que le nombre des entretoises pourrait être différent de quatre. Il faut au minimum trois entretoises pour rendre l'ensemble rigide. Les secteurs circulaires pourraient avoir un angle d'ouverture différent de 90°, et ce moyen de blocage des segments pourrait être constitué par un élément annulaire complet réalisé d'une seule pièce.The present invention is not limited to the embodiment described above, but it extends to any modification or variant obvious to a person skilled in the art. In particular, it is understood that the number of spacers could be different from four. A minimum of three spacers is required to make the assembly rigid. The circular sectors could have an opening angle different from 90 °, and this segment blocking means could be constituted by a complete annular element made in one piece.
