Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifting device for recovering a boat to a mother ship.

In general, it is extremely difficult to recover boats such as mission boats and work boats to their mother ships during rough weather.

In other words, during stormy weather, the rocking of the mother ship and boat causes the suspension fittings installed on the boat fall on the mother ship side to
It is not possible to easily and reliably connect the hanging fittings installed on the boat. In some cases, personal injury may occur due to shaking of the hanging fittings themselves during the connection work of the hanging fittings. SUMMARY OF THE INVENTION An object of the present invention is to provide a lifting device that allows a boat to be easily and reliably recovered to a mother ship without the above-mentioned dangers even in stormy weather.

To this end, the present invention provides a mother ship with a pair of cradles spaced apart from each other, a sheave of a boatfall and a fixed hook at the tip of each cradle, and one end of a substantially U-shaped hanging fitting at the bottom end of the boatfall. and the hanging fittings are connected to each other by a connecting rod having a buffer member on the outer periphery, and the fixing hook at the tip of each cradle is formed with an opening capable of locking the connecting rods on both sides of the buffer member, and The boat is equipped with a hook-shaped hanging fitting at one end, which has an open end that can be engaged with any position of the boat fall and can be engaged with the hanging fitting of the boat fall, and is detachable from the boat at the edge of the pond. It is characterized by providing a hanging means. Hereinafter, the present invention will be described with reference to illustrated embodiments.

In the present invention, as shown in FIG. 1, a pair of cradles 1 are provided on the side of a mother ship (not shown).

A sheave 3 of a boat fall 2 and a fixed hook 4 are provided at the tip of each cradle 1. A substantially U-shaped hanging fitting 5 is integrally fixed to the lower end of the boat fall 2 at the upper end of one leg 5a of the U-shape in alignment with the boat fall. The other leg portion 5b of the hanging fixture 5 is formed as a bracket. The brackets 5b of both boat falls 2 are connected to each other by a connecting rod 6. A buffer member 7 made of a shock-absorbing material such as urethane foam is attached to the outer periphery of the connecting rod 6 at a portion other than both ends 6a in the axial direction.
In the fixed hook 4 described above, when the boat fall 2 is hoisted by a winch (not shown) installed on the mother ship, both axial ends 6a of the connecting rod coincide with the opening □ of the hook 4,
Furthermore, by tilting the cradle upward, both ends 6a are formed into a shape that enters into the closed opening of the hook 4 and is locked to the hook 4. Further, in the present invention, a pair of slip hooks 9, 9 are fixed to the front and rear of the boat 8 by wires 10a, 1ob, and a hanging fitting unit 11 is detachably attached to each slip hook 9.

That is, the lower end of the unit 11 is formed as a link 12 that can be connected to or detached from the boat 8 by means of a slip hook 9. Also, unit 1
1 is formed as a hook-shaped hanging fitting 13 having an opening device. According to the above embodiment of the present invention, the boat 8 can be recovered to the mother ship in the following manner.

First, the boat fall 2 is lowered from the mother ship to below the sea surface. In this case, since the hanging fittings 5 of the front and rear boat falls 2 are connected to each other by the connecting rods 6, the shaking of the boat falls 2 is greatly suppressed even in rough weather, and the spacing between the boat falls 2 is always maintained. It will be kept constant. Note that a structure may be adopted in which the hanging fitting 5 at the lower end of the boat fall 2 is pulled toward the mother ship by the guide rope 14. Next, as shown in FIG. 3, the boat 8 is brought close to the boat fall 2, and the hanging fitting 13 of the unit 11, whose link 12 is connected to the slip hook 9, is hooked to an appropriate position on the boat fall 2. The only operation required on the boat to retrieve the boat is to hook the hanging fitting 13 to the boat oar 2. In this state, if you operate the winch on the mother ship to hoist Boat Fall 2,
As shown in FIGS. 4 and 5, the boat-side hanging fitting 13 moves along the boat fall 2 and comes into engagement with the hanging fitting 5 at the lower end of the boat fall 2.

Therefore, if the boat fall 2 is further hoisted, the boat will be lifted out of the sea. During this operation, the aforementioned guide rope 14 pulls the hanging fitting 5 toward the mother ship,
This is used to prevent the hanging fitting 13 from coming off the boat fall 2 and preventing personnel on the boat from coming into contact with the hanging fitting 5 and the connecting rod 6, resulting in injury or the like. Moreover, since the connecting rod 6 is provided with a buffer member 7 around its outer periphery over almost its entire length, the safety of the personnel on the boat is further increased. When the boat fall 2 is rolled up with the boat lifted, the connecting rods 6 on both sides of the buffer member 7 enter the hooks 4 at the tip of the cradle, and in this state, the cradle 1 itself is laid upward. As described above, the connecting rod 6 is locked in the hook 4 by the above-mentioned.

Needless to say, when the connecting rod 6 is locked in the hook 4, the boat is supported by the cradle. The procedure for lowering the port to the sea is almost the reverse of the procedure for recovering it.

After lowering the boat to the sea, it is sufficient to remove the boat-side hanging fitting unit 11 from the slip hook 9 as shown in Fig. 6, and if the boat is to be retrieved again, it is necessary to remove it from the slip hook 9. Of course, it is necessary to connect another hanging hardware unit 11 to the boat by means of the slip hook 9. As mentioned above, according to the present invention,
This provides the advantage that the boat can be recovered to the mother ship extremely easily, reliably, and safely even in stormy weather.
