• This vessel 1 is provided with a facility 2 for launching and recovery in a floating or submersible craft.
• this installation 2 comprises a lifting device 3 which is installed on the aforementioned bridge 11.
• This lifting device 3 could consist of a simple crane or a gantry crane. However, in the embodiment which is shown here, the lifting device 3 is somewhat different from a crane and its description is given below.
• This lifting device comprises four feet 30 and 30 'which are articulated on the bridge 11 and which together form a rectangular parallelepiped fictitious and deformable. As shown more particularly in FIGS. 1 and 2, two feet 30 are a pair and are connected by a cross member 31 so that the whole is a kind of "U" inverted.
• This pair of feet 30 is furthest from the edge of the bridge 1 1.
• the second pair of legs 30 ' which is closest to the deck edge, has a cross member which is articulated on the pair of feet 30'. This cross is referenced 31 '.
• the lifting device 3 further comprises a parallelepiped plate 33 which is arranged cantilevered, horizontally, near the top of the pairs of feet 30 and 30 '. More particularly, one end of this plate is articulated relative to the crossbar 31 and simply guided relative to the crossbar 31 '.
• This plate is largely cantilevered with respect to the pair of feet 30 and 30 'so that, in the position of FIG. 1 as well as in that of FIG. 4, a large part of this plate 33 is located in line with the water on which the ship is positioned.
• the plate 33 is provided with a movable carriage 34.
• the carriage 34 is provided with wheels 340 which can move along guide tracks that comprise the opposite edges of the plate 33, as shown particularly in FIGS. 1 and 2.
• the carriage 34 is provided with a lower face 341, the specific function of which will be explained below.
• This lower face has a rectangular horizontal surface of relatively large dimensions.
• the carriage 34 is equipped with a set of cables 35 which, in the position of Figure 1, are widely unwound. 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 FIG.
• these cables can be unwound so as to occupy a boat, which will be described below, a low position as shown in Figures 1 and 2 and, respectively, a high position. in which the cables are completely housed inside the carriage 34, as shown particularly in FIG. 4.
• the cable assembly 35 holds a basket 4 which is configured to support a machine consisting here, in the embodiment shown, in a vessel E boat. But it could be another type of gear, for example a mini submarine.
• This basket 4 comprises a semi-rigid float 40 which has the shape, viewed from above, of a "U” with a base 400 and two parallel wings 401.
• This "U” -shaped structure has an access opening 402 for the boat E, which opening is therefore opposite to the base 400 of the float 40.
• Said float 40 has the function of placing the basket at a height compatible with the boat to recover and allow said basket, when in the flotation position, to monitor the movements of water.
• This support structure is surmounted by a parallelepiped-shaped cage 43, which does not in any way conflict with the positioning of the boat in the basket 4 but which can at least partially cover it, as shown more particularly by the Figures 1 and 2.
• 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.
• the installation also comprises a guide member 5 which connects the basket 4 to a vessel wall, in this case the wall 10, which member 5 is configured to block the movements of the "lace” (horizontal movement of rotation about the vertical axis), of “cavally” (translation on the transverse horizontal axis) and of “yaw” (rotation on the longitudinal horizontal axis) of the basket 4 when 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 flotation position
• this guide member has the shape of a rod 5 which is made integral with a pair of arms 6 constituting a frame 60. More specifically, 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 hinged to the float. At the end of the arms 6 extends a pair of wheels, inflatable tubes or pads 601, the function of which will be explained later. The free end of the rod 5 has the shape of a sphere 50.
• the guide member in this case the rod 5, cooperates with a profile 7 having a generally vertical directional guide track 7 which is mounted on a wall of the vessel, in this case the wall 10, as shown in FIG. the figures.
• the spherical end 50 is configured to engage the section 7 and move in a vertical direction along the guide path. More specifically, the section 7 has, seen from above, the shape of a "C" with an opening 70 facing the basket 7. Its upper end is open so that the sphere 50 can be engaged in this profile from above only.
• the upper end of the profile 7 may advantageously be provided diverging upwardly and / or forwards and comprise for this purpose a set of plates 71 and 72 which gives the together a funnel shape.
• the lifting device 3 has been actuated so as to make it occupy the illustrated position 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 the water level, or even a little lower.
• the sphere 50 travels inside the profile, while the wheels (or rolls or pads) 601 bear on the wall 10 of the ship.
• the possible movements of the basket in a direction of translation in the direction of the ship 1 are prevented by the rod 5, as well as the movements of the wheels.
• 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 flotation position.
• the upper surface 430 of the basket 4 comes into direct contact, even in engagement with the lower surface 341 of the carriage 34, so that the basket 4 is somehow immobilized relative to the hoisting apparatus 2.
• the upper surface 430 of the basket 4 is here discontinuous, that is to say made of two parts facing one another. They therefore rest at the same time against the lower surface 341 of the carriage.
• the first essential difference lies in the fact that the guide member 5 'has a shape different from that described above.
• the two sections 7 have the function of guiding, as previously, the wheels 50 'during the ascent / descent of the basket 4.
• This material is integral with the carriage 34.
• arms 8 in this case two pairs of arms 8, which extend obliquely and downwardly from the carriage 34.
• each of these pairs is extended by a profile 80 which has the same shape and the same internal dimensions as the profiles 7.
• the assembly is configured so that in a raising / lowering position of the basket 4 ( Figures 6 to 9), the profiles 80 are supported on the top of the profiles 7 which they constitute in a way the extension.
• the basket 4 which receives the boat E is devoid of 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.
• 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 machines substantially identical templates.
• each upper face 403 mentioned abuts against the lower face 90 of two of the struts 9.
