Description

Dispositif de transport d'une torpille depuis un chariot d'acheminement vers un tube de lancement  Device for transporting a torpedo from a transport carriage to a launch tube
La présente invention concerne un dispositif de transport d'une torpille depuis un chariot d'acheminement vers un tube de lancement, notamment pour un navire de surface. The present invention relates to a device for transporting a torpedo from a carriage to a launch tube, in particular for a surface ship.
Dans un navire de surface, les torpilles sont stockées et préparées dans un premier local, et les tubes de lancement sont disposés dans un second local distant du premier local. Ainsi, lorsque l'on souhaite introduire une torpille dans un tube de lancement, il est nécessaire d'acheminer cette torpille depuis le premier local jusqu'au second local.  In a surface ship, the torpedoes are stored and prepared in a first room, and the launch tubes are disposed in a second room remote from the first room. Thus, when it is desired to introduce a torpedo into a launch tube, it is necessary to route the torpedo from the first room to the second room.
A cet effet, la torpille est habituellement disposée sur un chariot d'acheminement dans le premier local, ce chariot étant mobile pour permettre l'acheminement de la torpille jusqu'au second local. Toutefois, l'entrée du second local comporte habituellement un seuil qu'un tel chariot ne peut généralement pas franchir. Il est donc nécessaire de transporter la torpille depuis ce chariot d'acheminement vers le tube de lancement. Afin d'éviter toute erreur de manipulation, le transport de la torpille doit être sécurisé, et cela quel que soit l'état de la mer, dont quels que soient les mouvements du navire.  For this purpose, the torpedo is usually arranged on a carriage carriage in the first room, this carriage being movable to allow the transport of the torpedo to the second premises. However, the entrance of the second room usually has a threshold that such a truck can not usually cross. It is therefore necessary to transport the torpedo from this carriage to the launch tube. In order to avoid any mishandling, the transport of the torpedo must be secure, regardless of the state of the sea, regardless of the vessel's movements.
On connaît déjà, dans l'état de la technique, un chariot d'acheminement comprenant un système de translation permettant de translater la torpille depuis le seuil du second local jusqu'au tube de lancement. Toutefois, un tel système de translation n'est pas suffisamment sécurisé. En particulier, ce système de translation peut être entraîné par le poids de la torpille, notamment en cas de roulis. En outre, un tel chariot d'acheminement est particulièrement lourd, donc difficilement manœuvrable.  Already known in the state of the art, a transport carriage comprising a translation system for translating the torpedo from the threshold of the second room to the launch tube. However, such a translation system is not sufficiently secure. In particular, this translation system can be driven by the weight of the torpedo, especially in case of roll. In addition, such a transport carriage is particularly heavy, so difficult to maneuver.
L'invention a notamment pour but de remédier à ces inconvénients, en proposant un dispositif de transport d'une torpille depuis un chariot d'acheminement vers un tube de lancement, permettant un transport sécurisé de la torpille.  The object of the invention is in particular to remedy these drawbacks, by proposing a device for transporting a torpedo from a transport carriage to a launch tube, enabling secure transportation of the torpedo.

On a représenté, sur la figure 1 , un dispositif 10 de transport d'une torpille 12 depuis un chariot d'acheminement 14 vers un tube de lancement 16.  FIG. 1 shows a device 10 for transporting a torpedo 12 from a transport carriage 14 to a launch tube 16.
La torpille 12 et le tube de lancement 16 sont classiques et ne seront donc pas décrits en détail. Il est toutefois à noter que la torpille 12 présente, à l'arrière, une interface normalisée 17, notamment visible sur les figures 4 et 5.  The torpedo 12 and the launch tube 16 are conventional and will not be described in detail. It should however be noted that the torpedo 12 has, at the rear, a standardized interface 17, in particular visible in FIGS. 4 and 5.
Le tube de lancement 16 est disposé dans un local comportant une entrée 18 faisant face au tube de lancement 16. Cette entrée 18 comprend un seuil 20 empêchant le passage du chariot 14 dans le local. Le chariot 14 comporte un châssis 21 monté sur des moyens de roulement 22 classiques permettant le déplacement de ce chariot 14, et comporte des moyens de manœuvre 24, également de type classique. The launch tube 16 is disposed in a room having an inlet 18 facing the launch tube 16. This inlet 18 comprises a threshold 20 preventing the passage of the carriage 14 in the room. The carriage 14 comprises a frame 21 mounted on conventional rolling means 22 for moving the carriage 14, and includes operating means 24, also of conventional type.
Le chariot 14 comporte une partie d'accueil 26 destinée à recevoir la torpille 12. Il est à noter que la torpille 12 est de préférence sanglée lorsqu'elle est disposée sur cette partie d'accueil 26, pour des raisons de sécurité.  The carriage 14 comprises a reception part 26 intended to receive the torpedo 12. It should be noted that the torpedo 12 is preferably strapped when it is disposed on this reception part 26, for security reasons.
La partie d'accueil 26 est reliée au châssis 21 par l'intermédiaire de moyens de hissage 28 permettant de déplacer verticalement cette partie d'accueil 26 entre une position basse (représentée sur la figure 4) et une position haute.  The reception part 26 is connected to the frame 21 by means of hoisting means 28 for vertically moving this reception part 26 between a low position (shown in FIG. 4) and a high position.
La partie d'accueil 26 est préférentiellement dans sa position basse lorsque le chariot 14 est déplacé avec la torpille 12 disposée sur cette partie d'accueil. Ainsi, le centre de gravité de la torpille est bas, ce qui améliore la stabilité du chariot 14.  The reception part 26 is preferably in its lower position when the carriage 14 is moved with the torpedo 12 disposed on this reception part. Thus, the center of gravity of the torpedo is low, which improves the stability of the carriage 14.
Les moyens de hissage 28 permettent également de hisser la torpille 12 à hauteur du tube de lancement 16, comme cela est représenté sur les figures 1 ou 5. Cette position à hauteur du tube de lancement 16 peut être ladite position haute, lorsque le chariot est configuré pour faire coïncider cette position haute avec la hauteur du tube de lancement 16, ou en variante être une position intermédiaire entre la position basse et la position haute, auquel cas cette position intermédiaire est choisie par un opérateur.  The hoisting means 28 also make it possible to hoist the torpedo 12 at the height of the launching tube 16, as represented in FIGS. 1 or 5. This position at the height of the launch tube 16 can be said high position, when the carriage is configured to coincide this high position with the height of the launch tube 16, or alternatively be an intermediate position between the low position and the high position, in which case this intermediate position is chosen by an operator.
Le chariot 14 comporte enfin des moyens 23 de blocage au sol, de type classique, permettant d'immobiliser le chariot 14 en position, notamment face au tube de lancement 16, comme cela est représenté sur la figure 1 .  The carriage 14 also comprises conventional ground-locking means 23 for immobilizing the carriage 14 in position, in particular opposite the launching tube 16, as shown in FIG. 1.
Le dispositif de transport 10 comporte une structure de support 30, destinée à être agencée à proximité du tube de lancement 16. Dans l'exemple, la structure de support 30 comporte des montants inférieurs 32, 33 fixés au sol, en dessous du tube de lancement 16 correspondant. Pour une stabilité optimale, la structure de support 30 comporte par exemple deux premiers montants inférieurs verticaux 32, et deux seconds montants inférieurs inclinés 33 chacun reliés à un montant vertical 32 et fixé au sol.  The transport device 10 comprises a support structure 30, intended to be arranged close to the launching tube 16. In the example, the support structure 30 comprises lower uprights 32, 33 fixed to the ground, below the support tube. corresponding launch 16. For optimum stability, the support structure 30 comprises, for example, two first lower vertical uprights 32, and two second inclined lower uprights 33 each connected to a vertical upright 32 and fixed to the floor.
La structure de support 30 comporte par ailleurs des montants supérieurs 34, fixés aux montants inférieurs 32, 33 et s'étendant verticalement jusqu'au-dessus du tube de lancement 16.  The support structure 30 also comprises upper uprights 34, attached to the lower uprights 32, 33 and extending vertically up to the top of the launch tube 16.
Une première poulie 36 est portée par ces montants supérieurs 34, par l'intermédiaire d'une liaison pivot d'axe perpendiculaire à une direction longitudinale du tube de lancement 16.  A first pulley 36 is carried by these upper uprights 34, via a pivot connection axis perpendicular to a longitudinal direction of the launch tube 16.
La structure de support 30 comporte enfin une traverse de support 38, disposée sous le tube de lancement 16 et portée par les montants inférieurs 32, 33. Le dispositif de transport 10 comporte par ailleurs une structure de convoyage 40 représentée plus en détail sur la figure 2. The support structure 30 finally comprises a support cross member 38, disposed under the launch tube 16 and carried by the lower uprights 32, 33. The transport device 10 also comprises a conveyor structure 40 shown in more detail in FIG. 2.
La structure de convoyage 40 est destinée à être agencée entre le chariot d'acheminement 14 et le tube de lancement 16. Plus particulièrement, la structure de convoyage 40 est destinée à être fixée, de manière rigide, dans le prolongement du tube de lancement 16, de sorte que lorsqu'une torpille 12 est disposée sur cette structure e convoyage, l'axe de cette torpille 12 coïncide avec l'axe du tube de lancement 16, sans qu'il soit nécessaire de procéder à des réglages.  The conveying structure 40 is intended to be arranged between the conveying trolley 14 and the launching tube 16. More particularly, the conveying structure 40 is intended to be fixed, rigidly, in the extension of the launch tube 16 , so that when a torpedo 12 is disposed on this conveyor structure, the axis of this torpedo 12 coincides with the axis of the launch tube 16, without the need to make adjustments.
Cette structure de convoyage 40 comporte au moins un longeron 44, par exemple deux longerons 44 parallèles entre eux, s'étendant chacun entre une extrémité avant 44A destinée à être reliée à la structure de support 30, notamment à la traverse de support 38, par une liaison pivot, et une extrémité arrière 44B portée par un pied 46 de longueur variable, par exemple un pied 46 télescopique. Avantageusement, la liaison entre la seconde extrémité 44B et le pied télescopique 46 est une liaison pivot, ce qui permet de rabattre le pied 46 sur le longeron 44 pour le transport et le stockage de la structure de convoyage 40.  This conveyor structure 40 comprises at least one spar 44, for example two side members 44 parallel to each other, each extending between a front end 44A intended to be connected to the support structure 30, in particular to the support cross member 38, by a pivot connection, and a rear end 44B carried by a foot 46 of variable length, for example a telescopic foot 46. Advantageously, the connection between the second end 44B and the telescopic foot 46 is a pivot connection, which makes it possible to fold the foot 46 onto the spar 44 for transporting and storing the conveying structure 40.
Des moyens de réception et de guidage 42 de la torpille 12 sont portés par les longerons 44. Ces moyens de réception et de guidage comportent par exemple des paires de galets 48 alignés le long des longerons 44. Les galets de chaque paire 48 sont inclinés l'un vers l'autre de manière à former un creux de réception de la torpille 12. La torpille 12 est donc susceptible d'être disposée dans ce creux de réception, et guidée longitudinalement par les galets.  Receiving and guiding means 42 for the torpedo 12 are carried by the longitudinal members 44. These receiving and guiding means comprise, for example, pairs of rollers 48 aligned along the longitudinal members 44. The rollers of each pair 48 are inclined. one to the other so as to form a receiving hollow of the torpedo 12. The torpedo 12 is likely to be disposed in the receiving cavity, and guided longitudinally by the rollers.
La structure de convoyage 40 comporte avantageusement des poignées 50, par exemple fixées aux longerons 44, permettant le transport de cette structure de convoyage, généralement par deux opérateurs, afin de la disposer à son emplacement pour son utilisation.  The conveying structure 40 advantageously comprises handles 50, for example fixed to the longitudinal members 44, allowing the transport of this conveying structure, generally by two operators, in order to arrange it at its location for its use.
Comme cela est représenté sur la figure 4, la structure de convoyage 40 est mise en place tout d'abord en reliant la première extrémité 44A de chaque longeron 44 à la traverse de support 38 de la structure de support 30. Les longerons 44 sont alors susceptibles de basculer autour de la liaison pivot, pour amener la seconde extrémité 44B de chaque longeron 44 à une hauteur choisie par les opérateurs, par exemple afin de maintenir les longerons 44 horizontalement comme cela est représenté sur la figure 5. Les pieds 46 sont alors déployés pour maintenir ces secondes extrémités 44B à la hauteur choisie, et sont verrouillés en position.  As shown in FIG. 4, the conveyor structure 40 is put in place firstly by connecting the first end 44A of each spar 44 to the support cross member 38 of the support structure 30. The spars 44 are then able to tilt around the pivot connection, to bring the second end 44B of each spar 44 to a height chosen by the operators, for example to maintain the longitudinal members 44 horizontally as shown in Figure 5. The feet 46 are then deployed to maintain these second ends 44B at the chosen height, and are locked in position.
Le dispositif de transport 10 comporte par ailleurs une structure 52 d'entraînement de la torpille 12, comprenant un treuil 54 monté sur un support 56, un organe d'arrimage 58 destiné à être fixé à la torpille 12, et un câble d'entraînement 60 s'étendant au moins partiellement entre le treuil 54, autour duquel il est partiellement enroulé, et l'organe d'arrimage 58, en passant par la première poulie 36. Le treuil 54 est destiné à être disposé en arrière de la torpille 12, si bien que la torpille 12 est disposée entre le treuil 54 et la première poulie 36. The transport device 10 also comprises a structure 52 for driving the torpedo 12, comprising a winch 54 mounted on a support 56, a lashing member 58 to be attached to the torpedo 12, and a drive cable 60 extending at least partially between the winch 54, about which it is partially wound, and the securing member 58, through the first pulley 36. The winch 54 is intended to be arranged behind the torpedo 12, so that the torpedo 12 is disposed between the winch 54 and the first pulley 36.
Le câble d'entraînement 60 s'étend depuis une première extrémité 60A fixée à l'organe d'arrimage 58, passe par la première poulie 36, puis par le treuil 54, jusqu'à une seconde extrémité 60B également fixée à l'organe d'arrimage 58.  The drive cable 60 extends from a first end 60A fixed to the securing member 58, passes through the first pulley 36, then through the winch 54, to a second end 60B also attached to the member stowage 58.
Le câble d'entraînement 60 est par exemple enroulé sur au moins trois tours autour du treuil 54, de sorte que l'actionnement du treuil 54 permette d'entraîner le câble d'entraînement 60.  The driving cable 60 is for example wound on at least three turns around the winch 54, so that the actuation of the winch 54 can drive the drive cable 60.
Avantageusement, la structure d'entraînement 52 comporte une seconde poulie 62, également portée par le support 56, le câble d'entraînement 60 passant par cette seconde poulie 62, entre le treuil 54 et sa seconde extrémité 60B.  Advantageously, the drive structure 52 comprises a second pulley 62, also carried by the support 56, the drive cable 60 passing through the second pulley 62, between the winch 54 and its second end 60B.
Cette seconde poulie 62 est montée sur des moyens d'ajustement 64 permettant d'ajuster la distance entre cette seconde poulie 62 et le treuil 54, permettant ainsi d'assurer la tension du câble d'entraînement 60. Les moyens d'ajustement 64 sont par exemple formés par un bras inclinable muni de moyens 66 de réglage de l'inclinaison du bras 64.  This second pulley 62 is mounted on adjustment means 64 making it possible to adjust the distance between this second pulley 62 and the winch 54, thus making it possible to ensure the tension of the drive cable 60. The adjustment means 64 are for example formed by a tilting arm provided with means 66 for adjusting the inclination of the arm 64.
L'organe d'arrimage 58, représenté plus en détail sur la figure 3, comporte des moyens 68 de fixation à la torpille 12, notamment à l'extrémité arrière de cette torpille 12, et plus particulièrement à l'interface normalisée 17. L'organe d'arrimage 58 comporte par ailleurs un bras 70 solidaire de ces moyens de fixation 68, ce bras portant des premiers 72A et seconds 72B moyens d'accrochage au câble d'entraînement 60. Plus particulièrement, les premiers moyens d'accrochage 72A permettent l'accrochage de la première extrémité 60A du câble d'entraînement 60, et les seconds moyens d'accrochage 72B permettent l'accrochage de la seconde extrémité 60B du câble d'entraînement 60.  The securing member 58, shown in more detail in FIG. 3, comprises means for attachment to the torpedo 12, in particular at the rear end of this torpedo 12, and more particularly at the standardized interface 17. L stowage member 58 further comprises an arm 70 secured to these fastening means 68, this arm carrying first 72A and 72B 72B means of attachment to the drive cable 60. More particularly, the first attachment means 72A allow the attachment of the first end 60A of the drive cable 60, and the second attachment means 72B allow attachment of the second end 60B of the drive cable 60.
Le bras 70 s'étend entre une première extrémité 70A solidaire des moyens de fixation 68, disposée en dessous de ces moyens de fixation 68 dans une direction verticale, jusqu'à une seconde extrémité 70B disposée au-dessus de ces moyens de fixation 68 dans la direction verticale. Les premiers moyens d'accrochage 72A sont de préférence agencés à cette seconde extrémité 70B. En revanche, les seconds moyens d'accrochage 72B sont portés par le bras 70 sensiblement à hauteur des moyens de fixation 68.  The arm 70 extends between a first end 70A secured to the fixing means 68, disposed below these fixing means 68 in a vertical direction, to a second end 70B disposed above these fixing means 68 in the vertical direction. The first attachment means 72A are preferably arranged at this second end 70B. On the other hand, the second attachment means 72B are carried by the arm 70 substantially at the height of the fastening means 68.
Le bras 70 comporte une première partie 74, comprenant la première extrémité The arm 70 has a first portion 74, including the first end
70A, s'étendant sensiblement perpendiculairement à la direction verticale, et une seconde partie 76, comprenant la seconde extrémité 70B, inclinée par rapport à la direction verticale et formant un angle obtus avec la première partie 74, comme cela est représenté sur la figure 3. 70A, extending substantially perpendicular to the vertical direction, and a second part 76, comprising the second end 70B, inclined with respect to the vertical direction and forming an obtuse angle with the first part 74, as shown in FIG.
Cette forme de l'organe d'arrimage 58 permet d'éviter un basculement de la torpille 12 lorsqu'elle est tirée par le câble d'entraînement 60, notamment par sa première 60A ou sa seconde 60B extrémité.  This form of the securing member 58 prevents tilting of the torpedo 12 when it is pulled by the drive cable 60, in particular by its first 60A or 60B end.
En outre, l'inclinaison de la seconde partie 76 permet de transporter la torpille 12 dans le tube de lancement 16 jusqu'à sa position finale.  In addition, the inclination of the second portion 76 can transport the torpedo 12 in the launch tube 16 to its final position.
Le treuil 54 comporte une manivelle, et peut être actionné dans un premier sens, et dans un second sens opposé. Lorsque le treuil 54 est actionné, le câble d'entraînement 60 est entraîné, et tire alors sur l'organe d'arrimage 58, par l'intermédiaire de la première poulie 36 ou de la seconde poulie 62.  The winch 54 has a crank, and can be operated in a first direction, and in a second opposite direction. When the winch 54 is actuated, the drive cable 60 is driven, and then pulls on the securing member 58, via the first pulley 36 or the second pulley 62.
Dans le premier sens, le câble d'entraînement 60, à sa première extrémité 60A, entraîne l'organe d'arrimage 58, donc la torpille 12, par l'intermédiaire de la première poulie 36, en direction du tube de lancement 16.  In the first direction, the drive cable 60, at its first end 60A, drives the securing member 58, thus the torpedo 12, through the first pulley 36, towards the launch tube 16.
Dans le second sens, le câble d'entraînement 60, à sa seconde extrémité 60B, entraîne l'organe d'arrimage 58, donc la torpille 12, par l'intermédiaire de la seconde poulie 64, pour l'éloigner du tube de lancement 16.  In the second direction, the drive cable 60, at its second end 60B, drives the securing member 58, thus the torpedo 12, through the second pulley 64, away from the launch tube 16.
Avantageusement, le treuil 54 comporte des moyens anti-retour, empêchant une rotation de ce treuil 54 par traction sur le câble d'entraînement 60. Ainsi, la torpille 12 ne peut pas actionner le treuil par son poids, et ne peut donc pas se déplacer librement.  Advantageously, the winch 54 comprises non-return means, preventing a rotation of this winch 54 by traction on the drive cable 60. Thus, the torpedo 12 can not actuate the winch by its weight, and therefore can not move freely.
Les moyens anti-retour sont de type connu en soi, et comportent pas exemple une roue irréversible commercialisée sous l'appellation « Irréversible IR » par Ringspann®.  The anti-return means are of a type known per se, and do not include an irreversible wheel marketed under the name "irreversible IR" by Ringspann®.
Une telle roue irréversible agit dans les deux sens de rotation comme une roue libre à rouleaux équipée de roulements. Alors qu'une roue libre traditionnelle transmet le couple à partir de l'axe moteur dans un seul sens de rotation, dans le cas de la roue irréversible, l'axe moteur est entraîné dans les deux sens. Il y a cependant une action de blocage contre d'éventuels retours de couple en provenance de l'arbre entraîné, quel que soit le sens de rotation sollicité.  Such an irreversible wheel acts in both directions of rotation as a freewheel with rollers equipped with bearings. While a traditional freewheel transmits the torque from the motor axis in one direction of rotation, in the case of the irreversible wheel, the motor shaft is driven in both directions. However, there is a blocking action against possible torque returns from the driven shaft, regardless of the direction of rotation requested.
Un procédé de transport d'une torpille 12 depuis le chariot d'acheminement 14 vers le tube de lancement 16 va maintenant être décrit.  A method of transporting a torpedo 12 from the transport carriage 14 to the launch tube 16 will now be described.
Tout d'abord, le procédé de transport comporte une étape de fixation de la structure de support 30 à proximité du tube de lancement 16, comme cela est représenté sur la figure 4.  First, the transport method comprises a step of fixing the support structure 30 near the launch tube 16, as shown in FIG. 4.
Le procédé de transport comporte ensuite une étape d'accrochage de la première poulie 36 sur cette structure de support 30. Le procédé comporte ensuite une étape de mise en place de la structure de convoyage 40, en reliant la première extrémité 44A de chacun de ses longerons 44 à la traverse de support 38 de la structure de support 30. The transport method then comprises a step of hooking the first pulley 36 on this support structure 30. The method then comprises a step of setting up the conveyor structure 40, connecting the first end 44A of each of its longitudinal members 44 to the support cross member 38 of the support structure 30.
Le chariot d'acheminement 14 est alors acheminé jusqu'au seuil 20 du local du tube de lancement 16, de sorte que la torpille 12 se trouve dans l'alignement de la structure de convoyage 40, comme cela est représenté sur la figure 4.  The trolley 14 is then routed to the threshold 20 of the local launch tube 16, so that the torpedo 12 is in alignment with the conveyor structure 40, as shown in Figure 4.
Les moyens de hissage 28 du chariot 14 sont alors activés pour hisser la torpille 12 à hauteur du tube de lancement 16, comme cela est représenté sur la figure 5. La structure de convoyage 40 est également basculée autour de la liaison pivot avec la structure de support 30, pour placer les longerons 44 dans le prolongement de la partie de support 26 du chariot 14.  The hoisting means 28 of the carriage 14 are then activated to hoist the torpedo 12 to the height of the launch tube 16, as shown in FIG. 5. The conveying structure 40 is also pivoted around the pivot connection with the structure of the support 30, to place the longitudinal members 44 in the extension of the support portion 26 of the carriage 14.
Le procédé de transport comporte ensuite une étape d'installation de la structure d'entraînement 52 et de fixation de l'organe d'arrimage 58 à la torpille 12. Le treuil 34 est installé en arrière de la torpille 12, et le câble d'entraînement 60 est passé par la première poulie 36 puis fixé, à sa première extrémité 60A, ainsi qu'à sa seconde extrémité 60B, à l'organe d'arrimage 58.  The transport method then comprises a step of installing the drive structure 52 and securing the securing member 58 to the torpedo 12. The winch 34 is installed behind the torpedo 12, and the cable 60 is passed through the first pulley 36 and then fixed at its first end 60A and at its second end 60B to the securing member 58.
Le procédé comporte ensuite une étape de transport de la torpille 12, par actionnement du treuil 54, comme cela est représenté sur la figure 6. En actionnant le treuil 54, le câble d'entraînement 60 tire sur l'organe d'arrimage 58 en direction du tube de lancement 16 par l'intermédiaire de la première poulie 36.  The method then comprises a step of transporting the torpedo 12, by actuation of the winch 54, as shown in FIG. 6. By actuating the winch 54, the drive cable 60 pulls on the securing member 58 direction of the launch tube 16 through the first pulley 36.
On notera que la longueur de câble 60 déroulé reste constante, le câble 60 s'étendant continuellement entre ses deux extrémités 60A et 60B, toutes deux fixées à l'organe d'arrimage 58.  It will be noted that the length of cable 60 unwound remains constant, the cable 60 extending continuously between its two ends 60A and 60B, both fixed to the securing member 58.
Lorsqu'on souhaite ramener la torpille 12 sur le chariot 14, il suffit d'actionner le treuil 54 dans l'autre sens, afin de tirer la torpille 12 par la seconde extrémité 60B du câble.  When it is desired to return the torpedo 12 to the carriage 14, it suffices to operate the winch 54 in the other direction, in order to pull the torpedo 12 by the second end 60B of the cable.
On notera que l'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pourrait présenter diverses variantes supplémentaires.  Note that the invention is not limited to the embodiment previously described, but could have various additional variants.
Par ailleurs, il apparaît que le dispositif de transport 10 selon l'invention est facilement manipulable, par exemple par deux opérateurs. La structure de convoyage 40 pèse généralement environ 40 kg, et la structure d'entraînement 52 pèse également généralement environ 40 kg.  Furthermore, it appears that the transport device 10 according to the invention is easily manipulated, for example by two operators. The conveyor structure 40 generally weighs about 40 kg, and the drive structure 52 also typically weighs about 40 kg.
Le dispositif de transport 10 selon l'invention permet de sécuriser la torpille, même en cas de mer forte, car les moyens anti-retour du treuil 54 garantissent le maintien de la torpille 12, même lorsque l'opérateur lâche la manivelle. En outre, le treuil 54 permet de contrôler la progression de la torpille 12 par action directe sur la manivelle. Enfin, il est à noter que ce dispositif de transport 10 nécessite peu de place pour sa mise en œuvre, contrairement à un chariot de l'état de la technique capable d'assurer le transport, un tel chariot présentant un grand empattement et nécessitant donc de beaucoup d'espace pour sa mise en œuvre. The transport device 10 according to the invention makes it possible to secure the torpedo, even in strong sea conditions, since the anti-return means of the winch 54 guarantee the maintenance of the torpedo 12, even when the operator releases the crank. In addition, the winch 54 controls the progression of the torpedo 12 by direct action on the crank. Finally, it should be noted that this transport device 10 requires little space for its implementation, unlike a carriage of the state of the art capable of transporting, such a cart having a large wheelbase and therefore requiring a lot of space for its implementation.
