Description
La présente invention concerne un dispositif d'arrimage d'un objet à un bâtiment et, plus particulièrement d'une charge flottante ou d'un véhicule sous-marin autopropulsé ou non.The present invention relates to a device for securing an object to a building and, more particularly to a floating load or an underwater vehicle, self-propelled or not.
Les objets susceptibles d'être arrimés à un bâtiment tel qu'un bâtiment de surface peuvent être classés en deux grandes catégories.Objects likely to be stowed in a building such as a surface building can be classified into two main categories.
Une première catégorie comprend les charges flottantes qui peuvent être lourdes et volumineuses. De telles charges nécessitent des manoeuvres difficiles et dangereuses, notamment en cas de pilonnage par mer forte. Plusieurs dispositifs de récupération, de relevage et/ou d'arrimage ont été proposés, parmi lesquels on peut citer celui décrit dans les brevets français n° 2 152 886 et 2 073 192.A first category includes floating loads which can be heavy and bulky. Such loads require difficult and dangerous maneuvers, especially in the event of shelling in heavy seas. Several recovery, lifting and / or stowage devices have been proposed, including that described in
Les inconvénients de tels dispositifs sont qu'ils imposent de plaquer fermement la charge le long du navire et alors ils ne peuvent être utilisés pour la manutention de charges dont la structure extérieure est relativement fragile, ou qu'ils sont très spécifiques et donc non polyvalents.The drawbacks of such devices are that they force the load to be firmly pressed along the ship and then they cannot be used for handling loads whose exterior structure is relatively fragile, or that they are very specific and therefore non-versatile .
La deuxième catégorie comprend les véhicules sous-marins qui sont classés généralement en trois familles :
- la première concerne les véhicules passifs qui sont liés par un câble à un bâtiment porteur et que l'on déploie par gravité, le bâtiment étant pratiquement à l'arrêt,
- la deuxième concerne les véhicules passifs que l'on déploie à partir d'un bâtiment faisant route,
- la troisième concerne les véhicules propulsés évoluant autour du bâtiment à l'arrêt ou faisant route.
- the first concerns passive vehicles which are linked by a cable to a load-bearing building and which are deployed by gravity, the building being practically stationary,
- the second concerns passive vehicles that are deployed from a building under way,
- the third relates to powered vehicles moving around the stationary building or under way.
Les dispositifs d'arrimage relatifs à la première famille sont du même genre que ceux conçus pour les objets flottants car, dans ce cas, le véhicule peut être assimilé à une charge flottante.The securing devices relating to the first family are of the same kind as those designed for floating objects because, in this case, the vehicle can be treated as a floating load.
Les dispositifs de manoeuvre et d'arrimage et/ou de récupération des véhicules appartenant à la deuxième famille comportent un puits ménagé dans la coque du bâtiment et un réceptacle adapté pour recevoir ledit véhicule. Toutefois par mer forte, l'approche du véhicule sous le bateau reste une opération très délicate à effectuer.The devices for maneuvering and securing and / or recovering vehicles belonging to the second family include a well made in the hull of the building and a receptacle adapted to receive said vehicle. However in heavy seas, approaching the vehicle under the boat remains a very delicate operation to perform.
Des dispositifs relatifs aux véhicules de la troisième famille nécessitent la participation de plongeurs pour réaliser l'arrimage en surface, ou font appel à des gréements à prise automatique complexes et inefficaces par mer forte d'autant qu'une manoeuvre manuelle spécifique est exigée.Devices relating to vehicles of the third family require the participation of divers to secure the surface, or use complex and ineffective automatic setting riggings in heavy seas as much as a specific manual maneuver is required.
Enfin, il est à noter qu'en général tous les dispositifs connus, quels qu'ils soient, ne sont pas conçus pour arrimer des charges très lourdes, d'une tonne ou plus, comprenant des équipements fragiles et ayant une flottabilité presque nulle.Finally, it should be noted that, in general, all known devices, whatever they are, are not designed to secure very heavy loads, of one ton or more, comprising fragile equipment and having almost zero buoyancy.
Une charge lourde et fragile est constituée, par exemple, par un véhicule sous-marin autopropulsé qui est utilisé pour la détection des mines immergées notamment. Un tel véhicule comprend un sonar, des moyens de propulsion horizontal et vertical qui sont alimentés en énergie par un câble de liaison avec un bâtiment de surface, et dont la manoeuvrabilité est indépendante de l'orientation du câble.A heavy and fragile load is constituted, for example, by a self-propelled underwater vehicle which is used for the detection of submerged mines in particular. Such a vehicle comprises a sonar, horizontal and vertical propulsion means which are supplied with energy by a connection cable with a surface building, and whose maneuverability is independent of the orientation of the cable.
Les moyens traditionnels d'arrimage et/ou de manutention et de relevage sont inappropriés pour des véhicules comme celui qui vient d'être rappelé.Traditional means of securing and / or handling and lifting are unsuitable for vehicles like the one just mentioned.
On connaît des dispositifs de manoeuvre d'une charge à partir d'un bâtiment, du type comprenant un puits ménagé dans et débouchant à la partie inférieure de la coque du bâtiment, un cable de liaison passant à travers le puits et relié à la charge, un ensemble mobile de reprise qui est traversé par le cable de liaison, l'ensemble de reprise étant relié au bâtiment et susceptible d'être inséré au moins en partie dans le puits, tel le dispositif décrit dans le brevet US-A-4 372 597. Cependant, un tel dispositif présente l'inconvénient d'avoir un système complexe de positionnement de l'ensemble de reprise par rapport à la charge et de ne pas protéger le véhicule par mer forte.Devices for operating a load from a building are known, of the type comprising a well formed in and opening at the lower part of the hull of the building, a connecting cable passing through the well and connected to the load , a movable recovery assembly which is crossed by the connecting cable, the recovery assembly being connected to the building and capable of being inserted at least partially into the well, such as the device described in patent US-A-4 372 597. However, such a device has the drawback of having a complex system for positioning the recovery assembly with respect to the load and of not protecting the vehicle in heavy seas.
La présente invention a pour but de remédier aux inconvénients précités et de proposer un dispositif qui permette de mettre à l'eau, manoeuvrer et récupérer une charge active ou passive, le bâtiment étant à l'arrêt ou faisant route.
Selon la présente invention, le dispositif est du type comportant un câble de liaison passant à travers un puit ménagé dans le bâtiment et reliant un organe de manutention à la charge, un ensemble mobile de reprise, qui est traverse par le câble de liaison, l' ensemble de reprise étant relié au bâtiment et susceptible d'être rendu solidaire de la charge flottante pour l'arrimage à poste dans le puits.The present invention aims to remedy the aforementioned drawbacks and to propose a device which makes it possible to launch, maneuver and recover an active or passive load, the building being stopped or under way.
According to the present invention, the device is of the type comprising a connecting cable passing through a well made in the building and connecting a handling member to the load, a mobile recovery unit, which is crossed by the connecting cable, the recovery assembly being connected to the building and capable of being made integral with the floating load for securing station in the well.
Un avantage de la présente invention réside dans le fait que la charge peut être manoeuvrée même en mer forte.An advantage of the present invention lies in the fact that the load can be maneuvered even in heavy seas.
L'invention est caractérisée en ce que l'ensemble de reprise est constitué par une cloche susceptible d'être insérée au moins en partie dans le puits et en ce que des plaques formant une jupe prolongent la cloche et sont disposées de part et d'autre de la charge, de façon que le centre de gravité de l'ensemble constitué par la cloche et la charge lorsqu'ils sont rendus solidaires soit situé au moins au niveau du centre de volume et, de préférence, au dessous du centre de volume. Cette caractéristique est particulièrement intéressante lorsque la charge est un véhicule sonar car, alors, le bâtiment se trouve équipé d'un sonar de coque.The invention is characterized in that the recovery assembly consists of a bell capable of being inserted at least partially into the well and in that plates forming a skirt extend the bell and are arranged on either side other of the load, so that the center of gravity of the assembly constituted by the bell and the load when they are made integral is located at least at the center of volume and, preferably, below the center of volume . This characteristic is particularly advantageous when the load is a sonar vehicle because, then, the building is equipped with a hull sonar.
D'autres avantages et caractéristiques ressortiront mieux à la lecture d'un mode de réalisation de l'invention, donne à titre indicatif mais non limitatif, ainsi que du dessin annexe sur lequel :Other advantages and characteristics will emerge more clearly on reading an embodiment of the invention, given by way of indication but not limiting, as well as from the annexed drawing in which:
la figure 1 est une vue en coupe schématique du dispositif selon l'invention.Figure 1 is a schematic sectional view of the device according to the invention.
La figure 2 est une vue schématique en coupe, d'un lest d'arrimage.Figure 2 is a schematic sectional view of a tie down ballast.
La figure 3 est une vue en coupe schématique et partielle des moyens de guidage du lest d'arrimage à l'extrémité inférieure d'un puits de bâtiment de surface.Figure 3 is a schematic and partial sectional view of the means for guiding the ballast stowage at the lower end of a surface building well.
Dans un bâtiment de surface 1 est ménagé un puits 2 qui se termine sous la coque 3 par une embouchure 4 appropriée.In a surface building 1 is provided a
Une charge flottante 5, telle qu'un véhicule équipé par exemple d'un sonar, est suspendue à un câble de liaison 6 qui traverse le puits 2 et dont la manoeuvre est commandée à partir d'un treuil 7 organe de manutention, par exemple monte sur la structure du bâtiment 1.A
Un ensemble de reprise 8, représente à plus grande échelle sur la figure 2, est suspendu à au moins un câble de traction 9 traversant le puits 2 et s'enroulant par exemple sur un tambour d'un treuil 10 qui est monte également sur la structure du bâtiment 1. Le câble de liaison 6 traverse librement l'ensemble de reprise 8, de manière à rendre indépendant le mouvement du véhicule 5 de l'ensemble de reprise 8.A
L'ensemble de reprise (figure 2) se présente sous la forme d'une cloche ou cage tronconique 11 lestée et comprenant à sa partie inférieure un burrelet périphérique 12 servant de butée d'amortissement et de protection pour le véhicule 5 lors de l'arrimage. La forme tronconique de la cloche 11 est choisie de façon à permettre à l'ensemble de reprise de coiffer la partie supérieure du véhicule 5. De la même façon, la forme de l'embouchure 4 du puits 2 correspond à celle de la cloche 11 de l'ensemble de reprise 8 de manière à permettre une introduction la plus complète possible de ce dernier dans la coque du bâtiment 1.The recovery assembly (Figure 2) is in the form of a bell or
Des structures latérales 13 prolongent vers le bas la partie 11 et sont destinés à chevaucher le véhicule 5. Ces structures 13 sont également lestées, à leur extrémité inférieure, de telle sorte que le centre de gravité G du système constitué par l'ensemble de reprise 8 et le véhicule 5 soit situé au-dessous de son centre de volume. Cela permet d'assurer l'équilibre statique du système et lui donner une orientation correcte par rapport au bâtiment. Ces structures sont également équipées à leur partie inférieure de bourrelets de protection 12′.
Le câble 6 qui traverse la cloche 11 de l'ensemble de reprise 8, est guidé dans un manchon 14 susceptible d'être associé à des moyens 15, constitués par exemple par un vérin et une came, de serrage du câble 6 à l'intérieur du manchon 14. Une olive de protection et de crampage 16 est solidaire du câble 6 pour le protéger lorsque l'ensemble de reprise 8 coiffe le véhicule 5, tout en assurant la liaison entre la cloche 11 et le véhicule 5.The
Lorsque la véhicule 5 comprend un décrochement 5a ménagé à la partie supérieure arrière du véhicule 5, on peut prévoir des dérivés 19 sur la cloche 11 de manière à améliorer le positionnement angulaire relatif par rapport à l'axe vertical du système tel que défini ci-dessus, lorsqu'on effectue la reprise du véhicule 5 par la cloche 11. Des doigts 35 de guidage, prévus à l'extrémité supérieure de la cloche 11, sont susceptibles de s'introduire dans des passages 36 qui sont évasés vers le bas et qui sont ménagés dans le puits vertical 1.When the
L'arrimage à poste du véhicule 5 sous la coque du bâtiment 1 est réalisé de la façon suivante. Lorsque le véhicule 5 a été ramené à proximité du bâtiment 1, on laisse descendre l'ensemble de reprise 8 le long du câble 6, par déroulement du câble 9, sur quelques dizaines de mètres, mais en laissant un intervalle entre l'ensemble de reprise 8 et le véhicule 5. Comme l'ensemble de reprise 8 suit les mouvements de tanguage du bâtiment de surface, il faut que cet intervalle soit tel que l'ensemble de reprise 8 ne vienne jamais frapper le véhicule sous-marin 5.The stowage of the
L'ensemble de reprise 8 et le véhicule 5 sont ensuite remontés simultanément, par enroulement du câble 6 au moyen du treuil 7 et enroulement du câble 9 au moyen du treuil associé 10, les vitesses de remontée étant calculées de façon à ce que le véhicule 5 rattrape doucement l'ensemble de reprise 8, sans venir le heurter, même si le bâtiment de surface s'enfonce violemment dans l'eau.The
L'ensemble de reprise 8 et les moyens associés à la cloche 11 ont pour effet de raidir le câble de liaison 6, ce qui facilite, lorsque la cloche 11 est disposée dans l'embouchure 4 du puits 2, l'arrimage à poste sous la coque du bâtiment de surface, et de former un verrou de positionnement et d'orientation du véhicule sous-marin 5 par rapport au bâtiment de surface 1. L'utilisation en sonar de coque en découle immédiatement.The
Bien entendu, la présente invention n'est pas limitée au mode de réalisation donné dans la description mais en couvre au contraire, toutes les variantes.Of course, the present invention is not limited to the embodiment given in the description but on the contrary covers all variants.
