Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifting and recovering device for lifting and recovering an underwater vehicle onto a mother ship.

As a conventional lifting and retrieving device for underwater vehicles, there is one based on the hoisting and retrieving hook method as shown in Figure 1. The hook a is picked up by the underwater vehicle e by the operator on the mother ship i who operates the fishing rod d. (See code A in the first section.) Then, in the state where the lifting cable C is attached to the underwater vehicle e (see code B in Figure 1), the underwater vehicle e is moved by the crane b. It is recovered as shown in C.

(1) In addition to using the working means, the above installation requires a worker to go into the water and directly attach the lifting and retrieval line C to the underwater vehicle e.)
Measures are also being taken to

However, in the hoisting work using a hoisting hook like this,
When the sea is rough, both the mother ship j and the submersible vehicle e are shaken considerably, so it is difficult to attach the retrieval hook a with the fishing rod d when attaching the retrieval prime number from the mother ship i. There is a problem in that the work becomes uncertain, and there is also a problem in that the method of allowing workers to enter the water is accompanied by a very large danger.

The present invention is an attempt to solve these problems, and is to provide an underwater cruising vehicle that can reliably and safely retrieve an underwater vehicular vehicle onto a mother ship even when the sea is rough. The purpose is to provide a body lifting and recovery device.

For this reason, the underwater vehicle lifting and retrieval device of the present invention has two functions: before lifting and retrieving the underwater vehicle onto the mother ship, and a winch for winding the same lifting and retrieving line through the sheave of the crane. In addition, the above-mentioned pre-lifting and retrieving device is formed as a floating type pre-retrieving device that has buoyancy that allows it to float on the water surface, and the pre-lifting and retrieving catch that can engage with the retrieval line floating on the water surface is attached to the underwater vehicle. A device is provided on the upper part of the submersible vehicle to prevent the pre-lifting and unloading unit engaged with the pre-lifting catch tool from being pulled out from the catcher as it is hoisted by the winch when the underwater vehicle is lifted onto the mother ship. In order to prevent
The feature is that a stopper that is latched to the catcher is attached to the tip before lifting and retrieving.

Hereinafter, a lifting and recovering device for an underwater vehicle as an embodiment of the present invention will be explained with reference to the drawings. FIG. 2 is a side view thereof;
Fig. 3 is a plan view of the same, Fig. 4 is an explanatory view showing the state in which the buoyant body as a stopper is locked to the catch before lifting and retrieval, Fig. 5 is a view taken along the v-■ arrow in Fig. 6 and 7 are both detailed views of the lifting and retrieval line catcher showing an enlarged view of the V1 section of FIG. 5, and FIG. 8 is a side view showing a modified example of the crane.

As shown in FIGS. 2 and 3, the pre-lifting section 3 for lifting and recovering the underwater vehicle 6 to the mother ship 8'2 has one end connected to the sheave 7 attached to the tip of the crane 2. It is designed to be wound by a winch 1 for lifting and retrieving cables.

This pre-retrieval section 3 is formed as a floating-type pre-retrieval section with buoyancy that allows it to float above the water surface, and a retrieval line catcher 5 that can be engaged with this pre-retrieval section 3 is connected to an underwater vehicle 6. It is protruded from the top of the.

Further, after the pre-lifting and retrieving unit 3 is engaged with the pre-lifting and retrieving catch device 5 on the upper part of the underwater vehicle 6, it is pulled out from the retrieval line catcher 5 as it is hoisted by the retrieval line winch 1. To prevent this, a stopper 4a that is engaged with the pre-storage catch tool 5 is attached to the tip of the pre-storage 3.

Furthermore, a spherical buoyant body 4 is connected to the tip of the front 3.

4 and 5 show an example in which a buoyant body 4 connected to the tip of the front 3 is used as the stopper.

Furthermore, as shown in FIGS. 6 and 7, the catch device 5
is provided with a lock lever 16 to prevent the lifting front 3 engaged therewith from coming off, and the base end of the lock lever 16 is connected to a pin 17 on one side 15 of the opening of the hook-shaped catch body. The tip of the lock lever 16 is formed to engage with the tip of the catch main body 15. The mouth/clamp 161 is biased in a direction to close the opening of the catch body 15 by a leaf spring 18 attached to the catch body 15.

Since the underwater vehicle lifting and retrieving device of the present invention is configured as described above, when lifting and recovering the underwater vehicle 6 onto the ship 8, first, as shown in FIGS. Rub the levitation type hoist 3 so that it spreads out along the water surface.

In order to extend the pre-salvage 3 above the water surface, it may be manually thrown into the sea from the mother ship 8, or the buoyant body 4 at the tip of the pre-salvage 3 may be moved by gas pressure, etc., as shown by the reference numerals in Figure 2. The batter is sushi.

In addition, in order to extend the pre-lift 3, it is possible to install a propeller on the buoyancy body 4 and make it sail on the water surface. In the direction intersecting with
When the canter 5 on the upper part of the vehicle engages with the front 3 as indicated by the symbol IE in FIGS.

That is, the pre-lift 3 is engaged with the pre-lift catch tool 5 from the direction of the arrow in FIG.

In the state in which the lifting front 3 is inserted into the inside of the hook portion, the lock lever 16 is pushed back by the reaction force of the plate spring 18, as shown in FIG.

In this way, once the coupling between the pre-lift and recovery part 3 and the underwater vehicle 6 is completed, the pre-lift and recovery part 3 does not come off from the main body 15 of the Kya-Nochi soldier. A reliable connection can be achieved.

In addition, since the traveling speed of the underwater vehicle 6 is usually about 3 to 5 knots/ton, the above-mentioned means for engaging the lifting and receiving hole 3 and the catcher 5 does not allow the engagement. is easily performed.

Further, the lifting hole 3 connected to the underwater vehicle 6 is wound around the winch 1 for lifting and recovering via the sheave 7 at the tip of the crane 2.

Since a stopper 4a is attached to the tip of the lifting hole 3, when winding up the lifting hole 3, the lifting hole catch tool 5 will not come out of the lifting hole 3, and the water will not come out. The medium navigation vehicle 6 is drawn to the mother ship 8 side. This state is indicated by the symbol F in FIG.

Then, as indicated by the symbol G in FIGS. 2 and 3, the underwater vehicle 6 is hoisted up by the crane 2 and retrieved by the mother ship 8.

At this time, as shown in FIGS. 4 and 5, it is also possible to use the buoyant body 4 as a stopper.

Furthermore, in the apparatus of the present invention, the crane 2 does not need to be a special equipment, and may be a general-purpose crane 2' as shown in FIG. It is also possible to use a structure in which the winch 1 winds up the hoisting hole 3 via the winding hole 7'.

As described in detail above, according to the underwater vehicle lifting and retrieving device of the present invention, a lifting hole for lifting and retrieving an underwater vehicle onto a mother ship and a lifting cable are connected through a sheave of a crane. The hoisting hole is formed as a floating hoisting hole with buoyancy that allows it to float on the water surface, and a hoisting line catcher that can engage the hoisting line floating on the water surface. is provided in a protruding manner on the upper part of the underwater vehicle, and when the underwater vehicle is hoisted onto the mother ship, a hoisting hole engaged with the hoisting line canching device is hoisted by the winch. In order to prevent the underwater vehicle from being pulled out from the catch device, the simple structure is such that a stopper is engaged with the catch device, or a stopper is installed at the tip of the above-mentioned recovery hole, thereby improving the maneuverability of the underwater vehicle. This has the advantage that the underwater vehicle can be engaged with the recovery hole as the underwater vehicle travels, and even when the sea is rough, the underwater vehicle can be moved efficiently and safely. It has the effect of being able to be harvested.
