DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention est relative à un navire pourvu d'une installation de mise à l'eau et de récupération d'engins flottants ou submersibles, qui comprend un dispositif de levage comportant un ensemble de câbles qui retient un panier configuré pour supporter ledit engin lors desdites mise à l'eau et récupération.The present invention relates to a ship provided with an installation for launching and recovering floating or submersible devices, which comprises a lifting device comprising a set of cables which retains a basket configured to support said device when of said launching and recovery.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

On connaît déjà des navires pourvu d'une installation de mise à l'eau et de récupération d'engins flottants ou submersibles.We already know of vessels equipped with an installation for launching and recovering floating or submersible devices.

Ainsi, il existe des rampes fixes ou mobiles permettant à des embarcations de venir s'échouer sur la partie arrière d'un navire.Thus, there are fixed or mobile ramps allowing boats to run aground on the rear part of a ship.

Mais ces rampes doivent avoir une forme particulière pour s'associer à la forme de carène des embarcations. Dans ces conditions, cette forme spécifique nuit à leur polyvalence. Par ailleurs, les chocs occasionnés par l'échouement représentent un risque pour les personnes et/ou les embarcations.But these ramps must have a particular shape to match the hull shape of the boats. Under these conditions, this specific shape harms their versatility. Furthermore, the shocks caused by grounding represent a risk for people and/or boats.

On connaît aussi le système de radier qui est un compartiment ménagé à l'intérieur d'un navire qui peut être ouvert vers l'extérieur et immergé.We also know the raft system which is a compartment provided inside a ship which can be opened to the outside and submerged.

Dans certaines conditions environnementales, on observe à l'intérieur du radier des phénomènes d'amplification des mouvements d'eau qui représentent un risque lors des transferts. De plus, les manoeuvres de mise en eau du radier par ballastage sont des opérations longues et fastidieuses.Under certain environmental conditions, phenomena of amplification of water movements are observed inside the base, which represent a risk during transfers. In addition, the maneuvers for filling the raft with water by ballast are long and tedious operations.

Les bossoirs sont quant à eux des systèmes qui permettent de lever une embarcation en venant fixer un ou plusieurs crochets sur celle-ci, puis de la déplacer de l'extérieur vers l'intérieur du navire.Davits are systems which allow a boat to be lifted by attaching one or more hooks to it, then to move it from the outside to the inside of the vessel.

Mais ces bossoirs nécessitent que les embarcations soient spécialement équipées de points de levage.But these davits require the boats to be specially equipped with lifting points.

Par ailleurs, ces opérations à mener par l'équipage de l'embarcation (récupération du crochet ou du bras) sont des opérations risquées. Et elles ne sont pas compatibles avec des embarcations de type drone.Furthermore, these operations to be carried out by the crew of the boat (recovery of the hook or arm) are risky operations. And they are not compatible with drone type boats.

Les grues et les portiques dits "A Frame" sont des moyens de levage polyvalents qui peuvent être également utilisés dans ce contexte. Mais ils ont le même type de caractéristiques et de limites que les bossoirs cités plus haut, à la différence près qu'ils permettent aussi de récupérer des engins immergés (petit sous-marin d'exploration par exemple).Cranes and so-called “A Frame” gantry cranes are versatile lifting means that can also be used in this context. But they have the same type of characteristics and limits as the davits mentioned above, with the difference that they also allow submerged vehicles to be recovered (small exploration submarine for example).

On décrit dans le document FR-A-2401867 un dispositif de manutention d'un engin sous-marin, en l'espèce une tourelle de plongée.It is described in the document FR-A-2401867 a device for handling an underwater vehicle, in this case a diving turret.

Le dispositif de manutention comprend un seul câble relié à un "curseur" de remontée, lequel est guidé le long des rampes.The handling device comprises a single cable connected to a lifting "slider", which is guided along the ramps.

Le sommet de la tourelle coopère, via un organe male central, avec un dispositif de centrage positionné au-dessus du châssis du curseur. A ce système sont associés des plots amortisseurs.The top of the turret cooperates, via a central male member, with a centering device positioned above the slider frame. Shock absorber pads are associated with this system.

On constate aisément que la manipulation d'un tel dispositif n'est pas aisée et que la présence d'un câble en position centrale nuit à la stabilité de l'ensemble, dès lors que le guidage du curseur le long des rampes est mal engagé.It is easy to see that the handling of such a device is not easy and that the presence of a cable in the central position harms the stability of the whole, since the guidance of the cursor along the ramps is poorly engaged. .

Les documents DE 32 16 051 A1 , US 3536023 , GB2150903 , WO 2015/087074 , GB 2277718 , US 5941192 et EP 2468620 illustrent d'autres types de dispositifs de manutention.The documents DE 32 16 051 A1 , US 3536023 , GB2150903 , WO 2015/087074 , GB 2277718 , US 5941192 And EP 2468620 illustrate other types of handling devices.

De ce qui précède, il résulte qu'il existe un besoin non résolu de disposer d'un navire pourvu d'une installation de mise à l'eau et de récupération d'engins flottants ou submersibles qui soit la plus polyvalente et la plus sécurisée possible, afin qu'elle soit compatible avec une grande variété de taille et type d'engins à récupérer, qu'ils soient automatiques (drones) ou non.From the above, it follows that there is an unresolved need to have a vessel equipped with a installation for launching and recovering floating or submersible devices which is the most versatile and secure possible, so that it is compatible with a wide variety of sizes and types of devices to be recovered, whether automatic (drones) or not.

Par ailleurs, l'invention vise à ce que la manoeuvre de l'engin se passe dans les meilleures conditions, pour préserver le matériel mais également l'intégrité des personnes qui participent éventuellement à la manoeuvre.Furthermore, the invention aims to ensure that the maneuvering of the machine takes place in the best conditions, to preserve the equipment but also the integrity of the people who possibly participate in the maneuver.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention se rapporte donc à un navire pourvu d'une installation de mise à l'eau et de récupération d'engins flottants ou submersibles, qui comprend un dispositif de levage comportant un ensemble de câbles qui retient un panier configuré pour supporter ledit engin lors desdites mise à l'eau et récupération, lesdits câbles étant mobiles verticalement entre deux positions extrêmes, respectivement haute et basse, ledit panier comportant au moins une face supérieure qui est en appui contre au moins une surface, dite "surface de contact", dudit dispositif de levage, seulement lorsque lesdits câbles sont en position haute, caractérisé par le fait que :

  • ledit dispositif de levage comporte un chariot sur lequel est agencé l'ensemble de câbles, ce chariot étant configuré pour être déplacé horizontalement ;
  • le navire comporte un organe de guidage qui relie ledit panier à une paroi dudit navire, qui est configuré pour bloquer des mouvements éventuels de translation de type "embardée" et "cavalement" et de rotation de type "lacet" dudit panier, lorsque ce panier est en position de flottaison ;
  • ledit organe de guidage coopère avec une paire de profilés à chemin de guidage de direction généralement verticale, montés sur ladite paroi dudit navire, cet organe comportant des éléments configurés pour être engagés chacun dans un profilé et se déplacer en direction verticale le long dudit chemin de guidage lors desdites mise à l'eau et récupération ; et que
  • ledit chariot porte une paire de profilés qui sont configurés pour être amenés sélectivement au-dessus et dans le prolongement desdits profilés montés sur ladite paroi.
The present invention therefore relates to a ship provided with an installation for launching and recovering floating or submersible devices, which comprises a lifting device comprising a set of cables which retains a basket configured to support said device during said launching and recovery, said cables being movable vertically between two extreme positions, respectively high and low, said basket comprising at least one upper face which bears against at least one surface, called "contact surface", of said device lifting, only when said cables are in the high position, characterized by the fact that:
  • said lifting device comprises a carriage on which the set of cables is arranged, this carriage being configured to be moved horizontally;
  • the ship comprises a guide member which connects said basket to a wall of said ship, which is configured to block possible movements of translation of the "yaw" and "rolling" type and of rotation of the "yaw" type of said basket, when this basket is in the floating position;
  • said guide member cooperates with a pair of profiles with a guide path of generally vertical direction, mounted on said wall of said vessel, this member comprising elements configured to each be engaged in a profile and move in vertical direction along said path of guidance during said launching and recovery; and
  • said carriage carries a pair of profiles which are configured to be selectively brought above and in line with said profiles mounted on said wall.

Ainsi, du fait que ladite au moins face supérieure du panier vienne en appui directement contre une surface du dispositif de levage, les mouvements de balancier qui interviendraient normalement sont ici limités, de sorte que la sécurité des personnes qui participent à la manoeuvre est grandement améliorée.Thus, due to the fact that said at least upper face of the basket comes to bear directly against a surface of the lifting device, the pendulum movements which would normally occur are limited here, so that the safety of the people participating in the maneuver is greatly improved. .

Selon d'autres caractéristiques avantageuses de ce navire :

  • ladite "surface de contact" dudit dispositif de levage est constituée par au moins une partie d'une face inférieure dudit chariot ;
  • ladite "surface de contact" dudit dispositif de levage est constitué par la face inférieure de dispositifs stabilisateurs desdits câbles qui font saillie vers le bas depuis ledit chariot ;
  • ledit panier est pourvu d'au moins un flotteur ;
  • ladite "surface de contact" dudit dispositif de levage est constitué par la face inférieure de dispositifs stabilisateurs desdits câbles qui font saillie vers le bas depuis ledit chariot et que ledit flotteur comporte au moins une face supérieure qui est en appui contre ladite face inférieure desdits dispositifs stabilisateurs seulement lorsque lesdits câbles sont en position haute.
According to other advantageous characteristics of this ship:
  • said “contact surface” of said lifting device is constituted by at least part of a lower face of said carriage;
  • said “contact surface” of said lifting device is constituted by the lower face of stabilizing devices of said cables which project downwards from said carriage;
  • said basket is provided with at least one float;
  • said "contact surface" of said lifting device is constituted by the lower face of stabilizing devices of said cables which project downwards from said carriage and that said float comprises at least one upper face which bears against said lower face of said devices stabilizers only when said cables are in the high position.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Dans l'ensemble des figures annexées, le navire 1 dont il est question n'est que très partiellement représenté, ceci pour des raisons de simplification.In all of the appended figures, the ship 1 in question is only very partially represented, for reasons of simplification.

En l'occurrence, on s'est contenté de représenter une paroi 10 de ce navire, paroi généralement verticale qui peut être constituée par exemple par une partie de la coque du navire. On a également représenté une surface plane 11 qui est préférentiellement constituée par un pont supérieur 11 dudit navire.In this case, we have simply represented a wall 10 of this ship, a generally vertical wall which can be constituted for example by a part of the hull of the ship. There is also shown a flat surface 11 which is preferably constituted by an upper deck 11 of said ship.

Ce navire 1 est pourvu d'une installation 2 de mise à l'eau et de récupération dans un engin flottant ou submersible.This vessel 1 is provided with a launching and recovery installation 2 in a floating or submersible vehicle.

Plus particulièrement, cette installation 2 comprend un dispositif de levage 3 qui est installé sur le pont précité 11.More particularly, this installation 2 comprises a lifting device 3 which is installed on the aforementioned bridge 11.

Ce dispositif de levage 3 pourrait consister en une simple grue de levage ou un portique. Toutefois, dans l'exemple de réalisation qui est représenté ici, le dispositif de levage 3 est quelque peu différent d'une grue et sa description est donnée ci-après.This lifting device 3 could consist of a simple lifting crane or a gantry. However, in the exemplary embodiment shown here, the lifting device 3 is somewhat different from a crane and its description is given below.

Ce dispositif de levage comprend quatre pieds 30 et 30' qui sont articulés sur le pont 11 et qui forment ensemble un parallélépipède rectangle fictif et déformable. Comme le montrent plus particulièrement les figures 1 et 2, deux pieds 30 constituent une paire et sont reliés par une traverse 31 de sorte que l'ensemble constitue une sorte de "U" inversé.This lifting device comprises four feet 30 and 30' which are articulated on the bridge 11 and which together form a fictitious and deformable rectangular parallelepiped. As shown more particularly by the figures 1 And 2 , two feet 30 constitute a pair and are connected by a crosspiece 31 so that the whole constitutes a sort of inverted "U".

Cette paire de pieds 30 est la plus éloignée du bord du pont 11. La seconde paire de pieds 30', qui est la plus proche du rebord du pont, comporte une traverse qui est articulée sur la paire de pieds 30'. Cette traverse est référencée 31'.This pair of feet 30 is furthest from the edge of the bridge 11. The second pair of feet 30', which is closest to the edge of the bridge, includes a crosspiece which is hinged on the pair of feet 30'. This crosspiece is referenced 31'.

On a référencé 32 les moyens qui permettent d'actionner conjointement les pieds 30 de manière à leur impartir un mouvement de rotation de sorte qu'ils puissent passer d'une position basculée vers l'avant à une position basculée vers l'arrière, comme le montrent tout particulièrement les figures 1 et 5, respectivement.We have referenced 32 the means which make it possible to jointly actuate the feet 30 so as to give them a rotational movement so that they can move from a position tilted forward to a position tilted backwards, as this is particularly shown by the figures 1 And 5 , respectively.

Le dispositif de levage 3 comprend par ailleurs un plateau parallélépipédique 33 qui est disposé en porte-à-faux, horizontalement, au voisinage du sommet des paires de pieds 30 et 30'. Plus particulièrement, une extrémité de ce plateau est articulée par rapport à la traverse 31 et simplement guidée par rapport à la traverse 31'.The lifting device 3 also comprises a parallelepiped plate 33 which is arranged cantilevered, horizontally, at the vicinity of the top of pairs of feet 30 and 30'. More particularly, one end of this plate is articulated relative to the crosspiece 31 and simply guided relative to the crosspiece 31'.

Ce plateau est largement en porte-à-faux par rapport à la paire de pieds 30 et 30'de sorte que, dans la position de la figure 1 ainsi que dans celle de la figure 4, une grande partie de ce plateau 33 se trouve à l'aplomb de l'eau sur laquelle le navire est positionné.This plate is largely cantilevered relative to the pair of feet 30 and 30' so that, in the position of the figure 1 as well as in that of the Figure 4 , a large part of this plate 33 is located directly above the water on which the ship is positioned.

Le plateau 33 est pourvu d'un chariot mobile 34. A cette fin, le chariot 34 est pourvu de roues 340 qui peuvent se mouvoir le long de chemins de guidage que comportent les bords opposés du plateau 33, comme le montrent tout particulièrement les figures 1 et 2.The plate 33 is provided with a movable carriage 34. To this end, the carriage 34 is provided with wheels 340 which can move along guide paths which the opposite edges of the plate 33 have, as shown particularly in the figures 1 And 2 .

Le chariot 34 est pourvu d'une face inférieure 341 dont on expliquera plus loin la fonction spécifique. Cette face inférieure présente une surface rectangulaire horizontale, de relativement grandes dimensions.The carriage 34 is provided with a lower face 341, the specific function of which will be explained later. This lower face has a horizontal rectangular surface, of relatively large dimensions.

Le chariot 34 est équipé d'un ensemble de câbles 35 qui, dans la position de la figure 1, sont largement déroulés. Bien que cela ne soit pas visible, le chariot 34 intègre un dispositif d'enroulement de ces câbles de sorte que ceux-ci peuvent être déplacés verticalement, dans le sens de la double flèche f de la figure 2.The carriage 34 is equipped with a set of cables 35 which, in the position of the figure 1 , are largely unrolled. Although this is not visible, the carriage 34 incorporates a device for winding these cables so that they can be moved vertically, in the direction of the double arrow f of the figure 2 .

En d'autres termes, ces câbles peuvent être déroulés de manière à faire occuper à une embarcation, qui sera décrite plus loin, une position basse telle représentée par les figures 1 et 2 et, respectivement, une position haute dans laquelle les câbles sont complètement logés à l'intérieur du chariot 34, comme montré tout particulièrement à la figure 4.In other words, these cables can be unwound so as to cause a boat, which will be described later, to occupy a low position as represented by the figures 1 And 2 and, respectively, a high position in which the cables are completely housed inside the carriage 34, as shown particularly in figure 4 .

L'ensemble de câbles 35 retient un panier 4 qui est configuré pour supporter un engin consistant ici, dans le mode de réalisation représenté, en une embarcation E du genre bateau. Mais il pourrait s'agir d'un autre type d'engin, par exemple un mini sous-marin.The set of cables 35 retains a basket 4 which is configured to support a machine consisting here, in the embodiment shown, of a boat-like craft E. But it could be another type of machine, for example a mini submarine.

Ce panier 4 comporte un flotteur 40 semi-rigide qui a la forme, vu de dessus, d'un "U" avec une base 400 et deux ailes parallèles 401.This basket 4 comprises a semi-rigid float 40 which has the shape, seen from above, of a "U" with a base 400 and two parallel wings 401.

Cette structure en "U" ménage une ouverture d'accès 402 pour l'embarcation E, ouverture qui se trouve donc à l'opposé de la base 400 du flotteur 40.This “U”-shaped structure provides an access opening 402 for the boat E, an opening which is therefore opposite the base 400 of the float 40.

Entre les branches 401 de ce flotteur s'étendent des chainettes, des câbles, des chaînes, des sangles, un filet ou tout autre dispositif 42 dont la fonction est de supporter cette embarcation E.Between the branches 401 of this float extend chains, cables, chains, straps, a net or any other device 42 whose function is to support this boat E.

Ledit flotteur 40 a pour fonction de placer le panier à une hauteur compatible avec l'embarcation à récupérer et de permettre au dit panier, lorsqu'il est en position de flottaison, de suivre les mouvements de l'eau.The function of said float 40 is to place the basket at a height compatible with the boat to be recovered and to allow said basket, when in the floating position, to follow the movements of the water.

Cette structure de support est surmontée par une cage à claire-voie 43, de forme parallélépipédique, qui ne contrarie aucunement le positionnement de l'embarcation dans le panier 4 mais qui peut recouvrir au moins partiellement celle-ci, comme le montrent plus particulièrement les figures 1 et 2.This support structure is surmounted by a slatted cage 43, of parallelepiped shape, which in no way interferes with the positioning of the boat in the basket 4 but which can at least partially cover it, as shown more particularly in the figures 1 And 2 .

Cette cage 43 est dotée d'une face supérieure 430. Dans le cas représenté ici, cette face est plane, horizontale et discontinue (en deux parties). Mais il pourrait en être autrement.This cage 43 has an upper face 430. In the case shown here, this face is flat, horizontal and discontinuous (in two parts). But it could be otherwise.

Dans le mode de réalisation illustré sur les figures annexées, l'installation comporte également un organe de guidage 5 qui relie le panier 4 à une paroi du navire, en l'occurrence la paroi 10, organe 5 qui est configuré pour bloquer les mouvements de "lacet" ( mouvement horizontal de rotation autour de l'axe vertical), de "cavalement" (translation sur l'axe horizontal transversal) et d'"embardée" (rotation sur l'axe horizontal longitudinal) du panier 4 lors d'au moins une partie du mouvement vertical des câbles 35 selon la direction de la double flèche f, mais également lorsque le panier 4 est en position de flottaisonIn the embodiment illustrated in the appended figures, the installation also comprises a guide member 5 which connects the basket 4 to a wall of the ship, in this case the wall 10, member 5 which is configured to block the movements of "yaw" (horizontal movement of rotation around the vertical axis), "cavalage" (translation on the transverse horizontal axis) and "yaw" (rotation on the longitudinal horizontal axis) of the basket 4 during at least part of the vertical movement of the cables 35 in the direction of the double arrow f, but also when the basket 4 is in the floating position

Plus précisément, en référence à la figure 3 annexée, cet organe de guidage a la forme d'une tige 5 qui est rendue ici solidaire d'une paire de bras 6 constitutifs d'un cadre 60.More precisely, with reference to the Figure 3 annexed, this guide member has the form of a rod 5 which is made here integral with a pair of arms 6 constituting a frame 60.

Plus précisément, la tige 5 s'étend sensiblement parallèlement aux deux ailes 401 du flotteur 40 du panier 4 pendant la phase de transition. Cet organe de guidage est donc solidaire du cadre précité 60 qui est lui-même articulé sur le flotteur. A l'extrémité des bras 6 s'étend une paire de roues, de boudins gonflables ou de patins 601, dont on expliquera plus loin la fonction. L'extrémité libre de la tige 5 a la forme d'une sphère 50.More precisely, the rod 5 extends substantially parallel to the two wings 401 of the float 40 of the basket 4 during the transition phase. This guide member is therefore integral with the aforementioned frame 60 which is itself articulated on the float. At the end of the arms 6 extends a pair of wheels, inflatable tubes or skates 601, the function of which will be explained later. The free end of rod 5 has the shape of a sphere 50.

L'organe de guidage, en l'occurrence la tige 5, coopère avec un profilé 7 à chemin de guidage à direction généralement verticale, profilé 7 qui est monté sur une paroi du navire, en l'occurrence la paroi 10, comme montré sur les figures.The guide member, in this case the rod 5, cooperates with a profile 7 with a guide path in a generally vertical direction, profile 7 which is mounted on a wall of the ship, in this case the wall 10, as shown on the figures.

Ainsi que cela est particulièrement visible sur la figure 3, l'extrémité 50 en forme de sphère est configurée pour être engagée dans le profilé 7 et se déplacer en direction verticale le long du chemin de guidage. Plus précisément, le profilé 7 a, vu de dessus, la forme d'un "C" avec une ouverture 70 tournée vers le panier 7. Son extrémité supérieure est ouverte de sorte que la sphère 50 peut être engagée dans ce profilé par le haut uniquement.As is particularly visible on the Figure 3 , the sphere-shaped end 50 is configured to be engaged in the profile 7 and move in the vertical direction along the guide path. More precisely, the profile 7 has, seen from above, the shape of a "C" with an opening 70 turned towards the basket 7. Its upper end is open so that the sphere 50 can be engaged in this profile from above only.

Dans le but de faciliter un engagement de haut en bas, l'extrémité supérieure du profilé 7 peut avantageusement être prévue divergente vers le haut et/ou vers l'avant et comporter à cette fin un ensemble de plaques 71 et 72 qui confère à l'ensemble une forme d'entonnoir.In order to facilitate engagement from top to bottom, the upper end of the profile 7 can advantageously be provided diverging upwards and/or forwards and include for this purpose a set of plates 71 and 72 which gives the together a funnel shape.

Nous allons maintenant expliquer comment s'utilise l'installation décrite ci-dessus, tout d'abord en référence aux figures 1 et 2.We will now explain how the installation described above is used, first of all with reference to the figures 1 And 2 .

Sur ces figures, l'embarcation à rapatrier sur le pont du navire est déjà mise en place dans le panier 4.In these figures, the boat to be repatriated to the deck of the ship is already placed in basket 4.

Ceci suppose que, préalablement, le dispositif de levage 3 ait été actionné de manière à lui faire occuper la position illustrée où le plateau 33 est largement en surplomb de l'eau. Par ailleurs, on a piloté les câbles 35 de manière à ce qu'ils occupent une position basse dans laquelle le panier 4 se trouve au niveau de l'eau, voire un petit peu plus bas.This assumes that, previously, the lifting device 3 has been actuated so as to make it occupy the position illustrated where the plate 33 is largely overhanging the water. Furthermore, the cables 35 were controlled so that they occupy a low position in which the basket 4 is at water level, or even a little lower.

Ce faisant, lors du mouvement de descente, la sphère 50 du bras 5 s'est trouvée engagée à l'intérieur du profilé 7, cette manoeuvre étant facilitée par la forme en entonnoir de sa partie supérieure.In doing so, during the downward movement, the sphere 50 of the arm 5 found itself engaged inside the profile 7, this maneuver being facilitated by the funnel shape of its upper part.

Lors du mouvement de descente, la sphère 50 chemine à l'intérieur du profilé, tandis que les roues (ou boudins ou patins) 601 prennent appui sur la paroi 10 du navire. Pendant ce mouvement de descente mais également pendant le mouvement contraire de remontée, les mouvements éventuels du panier dans un sens de translation en direction du navire 1 sont empêchés par la tige 5, de même que les mouvements des roues. En revanche, les éventuels mouvements de "tangage" (rotation autour de l'axe horizontal transversal), "roulis" (rotation autour de l'axe horizontal longitudinal), "pilonnement" (translation sur l'axe vertical) ne sont pas bloqués lorsque le panier est en position de flottaison.During the downward movement, the sphere 50 travels inside the profile, while the wheels (or flanges or pads) 601 are supported on the wall 10 of the ship. During this downward movement but also during the opposite upward movement, possible movements of the basket in a direction of translation towards the ship 1 are prevented by the rod 5, as are the movements of the wheels. On the other hand, the possible movements of "pitch" (rotation around the transverse horizontal axis), "roll" (rotation around the longitudinal horizontal axis), "heave" (translation on the vertical axis) are not blocked when the basket is in the floating position.

Une fois que l'embarcation E a été mise en place sur le panier, qui est lui-même en position de flottaison, pour lui faire occuper la position des figures 1 et 2, on pilote alors l'enroulement des câbles de manière à faire remonter le panier en direction du chariot 34 et plateau 33.Once the boat E has been placed on the basket, which is itself in the floating position, to make it occupy the position of the figures 1 And 2 , we then control the winding of the cables so as to make the basket rise towards the carriage 34 and plate 33.

Lors de ce mouvement de remontée, les mouvements précités sont également bloqués, ce qui améliore grandement la sécurité des personnes qui soit se trouvent dans l'embarcation, soit se trouvent à proximité de l'installation.During this ascent movement, the aforementioned movements are also blocked, which greatly improves the safety of people who are either in the boat or who are near the installation.

Le mouvement de remontée est poursuivi jusqu'à ce que les câbles 35 occupent leur position haute, dans laquelle ils sont enroulés à l'intérieur du chariot 34.The upward movement is continued until the cables 35 occupy their high position, in which they are wound inside the carriage 34.

Ce faisant, la surface supérieure 430 du panier 4 vient en contact direct, voire en prise, avec la surface inférieure 341 du chariot 34, de sorte que le panier 4 est en quelque sorte immobilisé par rapport à l'appareil de levage 2.In doing so, the upper surface 430 of the basket 4 comes into direct contact, or even engages, with the lower surface 341 of the carriage 34, so that the basket 4 is in some way immobilized relative to the lifting device 2.

Comme mentionné plus haut, la surface supérieure 430 du panier 4 est ici discontinue, c'est-à-dire constituée de deux parties en regard l'une de l'autre. Elles s'appuient donc en même temps contre la surface inférieure 341 du chariot.As mentioned above, the upper surface 430 of the basket 4 is here discontinuous, that is to say made up of two parts facing each other. They therefore rest at the same time against the lower surface 341 of the carriage.

Mais on pourrait avoir aussi affaire à une seule surface supérieure 430 et à une surface inférieure 341 en deux parties, voire à des surfaces 430 et 341 en plusieurs parties, l'essentiel étant qu'elles s'appuient directement les unes contre les autres.But we could also be dealing with a single upper surface 430 and a lower surface 341 in two parts, or even with surfaces 430 and 341 in several parts, the main thing being that they rest directly against each other.

Lors de ce mouvement de remontée, la sphère 50 de la tige de guidage 5 s'est désengagée du profilé 7, comme le montre la figure 4. Ceci vient bien entendu du fait que le profilé a une hauteur bien inférieure à celle qui sépare le chariot 4 du niveau de l'eau.During this upward movement, the sphere 50 of the guide rod 5 disengaged from the profile 7, as shown in figure 4 . This of course comes from the fact that the profile has a height much lower than that which separates the carriage 4 from the water level.

Dans la position haute du panier 4, les éventuels mouvements de balancier de ce dernier sont supprimés puisqu'il devient "solidaire" du dispositif de levage 2.In the high position of the basket 4, any swinging movements of the latter are eliminated since it becomes "integral" to the lifting device 2.

Il suffit alors de piloter le chariot 34 ainsi que les pieds 30 et 30' du dispositif pour lui faire occuper la position extrême de la figure 5 dans laquelle l'embarcation E peut être déposée sur le pont 11 du navire.It is then sufficient to control the carriage 34 as well as the feet 30 and 30' of the device to make it occupy the extreme position of the figure 5 in which the boat E can be placed on deck 11 of the ship.

Le mode de réalisation illustré aux figures 6 à 10 présente de très grandes similitudes avec le précédent.The embodiment illustrated in figures 6 to 10 presents very great similarities with the previous one.

De ce fait, les références numériques des éléments communs à ces deux modes de réalisation sont identiques.As a result, the numerical references of the elements common to these two embodiments are identical.

Sauf exception, on décrira ci-après seulement les différences relatives à ce mode de réalisation conforme à l'invention.Unless there are exceptions, only the differences relating to this embodiment according to the invention will be described below.

La première différence essentielle réside dans le fait que l'organe de guidage 5' a une forme différente de celle décrite précédemment.The first essential difference lies in the fact that the guide member 5' has a shape different from that described previously.

A la paire de bras 6 constitutifs du cadre 60, on a affaire à une traverse 5' ici cylindrique dont les deux extrémités opposées portent des roues 50' ou autres organes roulants ou glissants de type patins, boudins gonflables, etc.With the pair of arms 6 constituting the frame 60, we are dealing with a crosspiece 5', here cylindrical, the two opposite ends of which carry wheels 50' or other rolling or sliding members such as skates, inflatable tubes, etc.

Par ailleurs, en lieu et place de l'unique profilé 7, on a affaire à une paire de profilés à section en forme de "C", leurs ouvertures respectives, dirigées verticalement, étant en regard l'une de l'autre.Furthermore, instead of the single profile 7, we are dealing with a pair of profiles with a "C" shaped section, their respective openings, directed vertically, facing each other.

Les deux profilés 7 ont pour fonction de guider, comme précédemment, les roues 50' lors de la remontée / descente du panier 4.The two profiles 7 have the function of guiding, as previously, the wheels 50' during the raising/lowering of the basket 4.

Ces profilés 7 sont avantageusement prévus fixes. Toutefois, ils pourraient être coulissants par rapport à la paroi 10, de manière à pouvoir escamoter vers le bas leur extrémité supérieure, qui lors du fonctionnement du dispositif, s'élève au-dessus du plan du pont 11.These profiles 7 are advantageously designed to be fixed. However, they could be sliding relative to the wall 10, so as to be able to retract downwards their upper end, which during operation of the device, rises above the plane of the bridge 11.

Sur les figures est également représenté un matériel additionnel stabilisateur qui peut, le cas échéant, être associé aux profilés 7.The figures also show additional stabilizing material which can, if necessary, be associated with the profiles 7.

Ce matériel est solidaire du chariot 34.This material is integral with the carriage 34.

Il comprend ici des bras 8, en l'occurrence deux paires de bras 8, qui s'étendent obliquement et vers le bas depuis le chariot 34.Here it comprises arms 8, in this case two pairs of arms 8, which extend obliquely and downwards from the carriage 34.

L'extrémité inférieure de chacune de ces paires se prolonge par un profilé 80 qui présente la même forme et les mêmes dimensions intérieures que les profilés 7.The lower end of each of these pairs is extended by a profile 80 which has the same shape and the same internal dimensions as the profiles 7.

L'ensemble est configuré pour que dans une position de remontée / descente du panier 4 (figures 6 à 9), les profilés 80 viennent s'appuyer sur le sommet des profilés 7 dont ils en constituent en quelque sorte le prolongement.The assembly is configured so that in a raising/lowering position of the basket 4 ( figures 6 to 9 ), the profiles 80 come to rest on the top of the profiles 7 of which they constitute a sort of extension.

Dans ces conditions, lors du déplacement du panier 4 en position haute, les roues 50' quittent les profilés 7 pour s'engager dans les profilés 80.Under these conditions, when the basket 4 is moved to the high position, the wheels 50' leave the profiles 7 to engage in the profiles 80.

Par ailleurs, dans la mesure où ces profilés 80 sont solidaires du chariot 34, les roues 50' restent prisonnières des profilés 80, même lors de la manoeuvre extrême (figure 10) de transfert de l'embarcation E sur le pont 11 du navire. Là encore, cette opération est réalisée avec une embarcation parfaitement stable.Furthermore, to the extent that these profiles 80 are integral with the carriage 34, the wheels 50' remain trapped in the profiles 80, even during the extreme maneuver ( Figure 10 ) transfer of boat E to deck 11 of the ship. Here again, this operation is carried out with a perfectly stable boat.

Dans le mode de réalisation de la figure 11, l'installation est quasiment identique à celle des figures 6 à 10.In the embodiment of the Figure 11 , the installation is almost identical to that of figures 6 to 10 .

Toutefois, on a affaire ici à quatre câbles 35 qui retiennent le panier 4, chaque câble étant associé à un dispositif stabilisateur 9, appelé en termes de métier "bracon", qui a pour fonction de guider les câbles et de les maintenir écartés deux à deux. Lorsque le panier 4 est déplacé vers sa position haute, alors la surface 430 précitée vient s'appuyer contre la face inférieure 90 de chacun des bracons. En l'occurrence, deux bracons sont en contact avec une première partie de la surface 430 et les deux autres avec la seconde partie.However, we are dealing here with four cables 35 which hold the basket 4, each cable being associated with a stabilizing device 9, called in professional terms "bracon", which has the function of guiding the cables and keeping them apart two to two. When the basket 4 is moved to its high position, then the aforementioned surface 430 comes to rest against the lower face 90 of each of the braces. In this case, two braces are in contact with a first part of the surface 430 and the other two with the second part.

Le mode de réalisation qui est représenté à la figure 12 est extrêmement proche du précédent.The embodiment which is represented in Figure 12 is extremely close to the previous one.

En effet, on fait également usage ici de dispositifs stabilisateurs 9 ("bracons") similaires à ceux précédemment décrits, mais de longueur importante.In fact, we also use here stabilizing devices 9 ("bracons") similar to those previously described, but of significant length.

Par ailleurs, le panier 4 qui reçoit l'embarcation E est dépourvu de cage 43, de sorte que les câbles 35 associés aux dispositifs stabilisateurs 9 sont rattachés à la face supérieure 403 des ailes 401 du flotteur 40 du panier 4. Dans ce mode de réalisation, la longueur des dispositifs stabilisateurs est sensiblement identique à la hauteur de la cage 43 décrite dans les autres modes de réalisation, pour permettre la récupération d'engins flottants de gabarits sensiblement identiques.Furthermore, the basket 4 which receives the boat E does not have a cage 43, so that the cables 35 associated with the stabilizing devices 9 are attached to the upper face 403 of the wings 401 of the float 40 of the basket 4. In this mode of embodiment, the length of the stabilizing devices is substantially identical to the height of the cage 43 described in the other embodiments, to allow the recovery of floating devices of substantially identical sizes.

Dans ces conditions, lorsque l'embarcation E effectue sa remontée, chaque face supérieure 403 précitée vient en appui contre la face inférieure 90 de deux des bracons 9.Under these conditions, when the boat E makes its ascent, each upper face 403 mentioned above comes to bear against the lower face 90 of two of the braces 9.

On constate de la description qui précède que l'ensemble des manoeuvres de récupération ou de mise à l'eau de l'engin flottant ou non sont largement sécurisées par le fait que les mouvements éventuels de translation ou de rotation sont parfaitement maîtrisés. En conséquence, les manoeuvres peuvent se faire en toute sécurité.It can be seen from the preceding description that all of the recovery or launching maneuvers of the floating or non-floating device are largely secured by the fact that any translation or rotation movements are perfectly controlled. Consequently, maneuvers can be done in complete safety.
