SU1373312A3 - Arrangement for launching on water and hoisting life or hoisted boat from ship or stationary installation - Google Patents

Abstract

An assembly for launching or retrieving a lifeboat (12), pick-up boat or the like from a ship (10) or a stationary installation includes a boat dock (1) having float bodies (2,3). Control wires (17) extending down to the sea from the ship (10) or the stationary installation cooperate with guide means (6,7) on the boat dock (1) to control the dock during lowering and hoisting. The control wires (17) have weights (18) at their free ends, which hold the wires taut at all times. The weights are lowered while suspended from the control wires and are submersed in the water, or may optionally rest on the sea bed, in which case the control wires are tensioned by means of winches (16) on board the ship (10) or on the stationary installation. In this manner, the boat dock (1) can float in the sea and follow the wave movements, while at the same time it is stabilized due to the control of the wires (17). There is a coupling means (5) on the boat dock (1) which engages with a coupling means (21) on the boat (12) when the boat is in the dock. <IMAGE>

11 device. The device contains a boat form 1 with floats 2,3. The control cables 17 pass from the ship 10 or the fixed installation and interact with the guide means 6.7 on the boat form 1. At the same time, the form of the cables is controlled during its descent or ascent. On the control cables 17 there are loads 18 suspended from their free condes, these weights holding the cables all the time in a tensioned state. Loads are being lowered, overhanging on up12

Equal ropes, and immersed in water, they can also be lowered to the seabed, in this case, the control ropes are pulled by winches 16, which are aboard ship 10 or a fixed installation. Boat form 1 can float in the sea and move under the action of waves, while it is stabilized with control cables 17. There is a locking device 5 on boat form 1, which engages counter element 21 on boat 12 when the boat is inside the form. 6 Il.

The invention relates to shipbuilding, in particular to ship devices for launching boats.

The aim of the invention is to improve the usability of the device.

FIG. 1 shows a device, a general view; FIG. 2 - the same, when carrying out the load in the form of a slide; FIG. 3 the same, without a boat in boat form; in fig. A - boat shape, side view; in fig. 5 and 6 - locking device.

The device consists of a boat form 1, which contains two floats 2 and 3, the floats are located at a distance from each other and parallel to each other and are interconnected by means of the portal frame A. In the center of the traverse of the portal frame there is a back device 5. In the floats 2 and 3, there are vertical through holes or similar guiding means 6.7 and 8.9, respectively. In the boat frame shown in FIG. 1, only guides 6 and 7 are used in the same float 3. In the float 2, these through holes may not be, since they are not used in the embodiment shown in FIG. 1, but the guide holes in both pontoons are used in the embodiment shown in FIG. 2

On the ship or in a fixed installation 10 there is a protruding

platform 11 is outward. In platform 11 there is a substantially rectangular opening (not shown), this opening corresponds to the boat shape

1, as well as the boat 12, which is lowered and raised by mold 1. A crane 13 is placed on platform 11. A crane is equipped with a self-tapping winch 14, and a guide pulley 15 is suspended from the crane 11. Under platform 11 there are one or more winches 16 at the base of the crane 13. Cable 17 passes from winch 16

up to the guide pulley 15, then passes around the pulley, and then goes down, the passage through the guide hole 6 in the float 3. The load 18 is suspended to one end of the cable 17. In a similar way, the second cable (not shown) is directed either from the same winch 16, or from a similar winch around the second pulley 15 and then down through the guide hole 7 in the float 3, the second cable is also provided with a load similar to the load 18.

Cable 19 departs from automatically pulling winch 14 down to

boat form 1, where it is attached to form 1, in this case to its portal frame 4 at the locking device 5, which forms part of the frame.

The locking device is shown in FIG. 4 - 6.It has a body with a groove

20, open at the bottom and from two ends, the ball 21 enters this groove 20. Ball 21

located at the end of the rod 22, which is attached to the boat accordingly. The ball 21 is fixed in the groove 20 with a Lomoschmy two spring loaded latches 23 and 24, which automatically secure the ball when it enters the slot. To release the connection, the latches 23 and 24 are pulled out against the action of the spring, while the ball is released.

The device shown in FIG. 1, is used as follows. A boat shape with a boat 12 tightly attached thereto is placed in the opening of the platform 11 and secured in this position, or alternatively they can only be hung on the cable 19. The winch or winches are actuated to lower the boat 12 16 to lower the cable 17, while the weights 18 present at the ends of the cable keep it taut The cables 17 are moved until the weights 18 are submerged; Sometimes the loads can be lowered further to the bottom of the sea, after which they are pulled by a winch 16, which can be of self-sinking type. Then, using the winch 14 and the cable 19 associated with it, the boat mold 1 with the boat 12 can be lowered. During this operation, the float 3 is controlled by the cable 17, which passes through the guide holes 6 and 7. When the spring mold reaches the surface and floating, it can not move under the action of waves. But he will always be under the stabilizing control of the cable 17. After opening the locking device, the boat can be taken out of the mold.

To lift the boat, it is inserted into boat form 1, which can or be located on the surface of the sea, it should be lowered beforehand. to the surface in the manner described. The locking device is locked and the boat form with the boat lifts as one piece, and the cables are stabilized 17.

The difference between the device shown in FIG. 2-4, from the device described in FIG. 1 consists in the use of the Research Institute of four control cables 25. Each control cable rises to a separate winch 29 corresponding to it on the crane. A crane 13, a ship or a constant

ka 10, as well as platform 11, are essentially the same as pre,; one.

Control cables 25-28 are connected in pairs with a corresponding load, made in the form of a V-shaped launch cage 30 and 31, respectively, for example, i.e. control cables 25 and 27

both are connected with one sled 30, and cables 25 and 26 with other sled 31. These sleds are the same. Two sled 30 and 31 can be interconnected, for example, one

or two longitudinal beams (not shown).

When using this device, the pusher mold 1 with the boat 12 is placed in the orifice of the platform 11, and the carriage 30 and 31 are lowered. The boat form with the boat 12 can be lowered simultaneously with the carriage 30 and 31. 1 and 5, and since the boat form 1 floats on water, you can release the boat 12 as described above. To lift the boot, the weights are lowered and the control cables are kept taut, at this time the boat form 1 is floating, controlled by cables. Boat 12 is inserted into and attached to the form, and

the boat form together with the boat 12 is lifted by winches and control cables 25 to 28. This option can also be modified so that the boat form 1 can

all the time be connected by a cable with a self-winding winch mounted on the crane, as shown in FIG. one.
