FIG.

Referring to FIG. 2, the rotating tower type life-saving launching apparatus includes a plurality of lifeboats 10 that are coupled to a rotating tower structure, a rotating tower structure, and a hook unit 230 interposed therebetween, And a guide rail structure 260 that forms a launch path of the guide rail assembly 10.

The rotary tower structure may include a support column 210 fixed to the deck 1 and a circular structure 220 connected to one side of the support column 210 through a rotation part 215. [

The lifeboat 10 is fastened to the plurality of positions of the circular structure 220 via the hook unit 230. When the shipboard is loaded on the lifeboat 10 as described later, And is rotated by the self weight of the lifeboat 10 with the rotation part 215 fixed to the lifter 10 as the center of rotation. FIG. 2 illustrates the case where four lifeboats 10 are mounted at intervals of 90 degrees of rotation. However, the number of lifeboats 10 to be installed can be increased or decreased as needed.

The rotary tower structure is installed on the side of the residence, which is the space where the passengers stay, and the passengers can board the lifeboat 10 fastened to the circular structure 220 through the boarding floor 270 extending from the upper level of the residence. And the increase in the weight of the lifeboat 10 due to the boarding of the ship is used as a driving force for rotating the circular structure 220 around the rotation part 215 as a center of rotation.

The rotation unit 215 may include a ratchet wheel that is rotated by the rotational force of the life preserver 10 due to its own weight and is prevented from rotating in the reverse direction, for example.

The circular structure 220 may be formed of a plate-shaped member, but may be formed using a plurality of concentric ring members to reduce air resistance and the like.

A guide rail structure 260 (see FIG. 2) is provided below the vertical axis of the circular structure 220 to provide a path for launching the lifeboat 10, which is moved downward ) Is installed.

1, the guide rail structure 260 may include a guide rail formed by a main guide bar and a sub guide bar to extend the guide distance. In addition, the guide rail structure 260 may include a path for launching the lifeboat 10 to the water surface It should be understood that the present invention can be applied without any limitation.

As described above, the circular structure 220 is rotated so that the lifeboat 10 aboard the ship is moved by its own weight from the boarding position to the innermost position.

At this time, there may be a case where the lifeboat 10 passes the center position due to the rotational force applied to the circular structure 220. This may be caused by the rotation of the circular structure 220, ) May not be able to stop at the correct position. However, as described above, since the rotation portion 215 is configured to be prevented from rotating in the reverse direction, the lifeboat 10 that has passed the boarding position can not be readjusted to the proper boarding position, which allows the boarding personnel to safely board the lifeboat 10 This can cause problems that can not be solved.

In order to prevent such a problem, a movement stopping member 250 is attached to a lower portion of the support post 210 to allow the lifeboat 10, which is moved to the loading position, to stop moving accurately at a designated position.

The movement blocking member 250 is configured to support the chain 410 (see FIG. 4) of the lifeboat 10 fastened to the hook unit 230 that fixes the lifeboat 10 to the circular structure 220, And is mounted at a position on the column 210. The movement blocking member 250 is configured to provide a minimum of impact to the lifeboat 10 connected to the chain 410 by absorbing the impact on the chain 410 in the event of a collision with the chain 410, Foamed elastic foam such as polyurethane foam.

Hereinafter, the operational state of the rotating tower lifeboat launching apparatus will be described with reference to FIG. 3 and FIG.

Referring to FIG. 3 (a), when an emergency situation requiring escape occurs in the floating floating structure, the passengers are placed on the lifeboat A located at the boarding position through the boarding floor 270 at the upper level of the residence Board. At this time, the lifeboat A may be fixed to the boarding floor 270 using a fixing device 235 (see FIG. 2) so that the boat is not dropped by its own weight during boarding. The fixing device 235 may be detachable from the lifeboat A and the life-saving device A may cause the prototype device 220 to start rotation by self-weighting by detaching the fixing device 235.

When the circular structure 220 is rotated by the self weight of the lifeboat A, the lifeboat A is moved from the loading position to the starting position (i.e., the lower position on the vertical axis of the circular structure 220 and the upper position of the guide rail structure 260) And the following lifeboat B will be moved to the boarding position (see FIG. 3 (b)).

At this time, in order to prevent the movement of the chain 410 for fastening the lifeboat A to the hook unit 230 so that the lifeboat A can be accurately stopped at the cranking position, A movement blocking member 250 formed of an elastic foam is mounted.

3C, the shipowners located in the residence area newly fix the lifeboat B moved to the boarding position to the boarding floor 270 using the fixing device 235, and then the lifeboats B .

The passengers aboard the lifeboat A confirm that the lifeboat B is fixed to the boarding floor 270 using the fixing device 235 and then release the hooking state of the hook unit 230 fixing the lifeboat A to the circular structure 220 So that the lifeboat A is separated from the hook unit 230. The lifeboat A separated from the hook unit 230 is advanced to the water surface along the path provided by the guide rail of the lower guide rail structure 260.

4, in which the shape of the hook unit 230 is illustrated, the hook unit 230 includes a body 420, a latch ring 430, a lever 450, and a loop fastener 460. [

The body 420 is rotatably coupled to the circular structure 220 by a hinge portion 415 so that the lifeboat 10 is positioned on the circular structure 220 regardless of the current position of the lifeboat 10, Can be maintained.

The hook 430 is rotatably coupled to one side of the main body 420 by a first pin 440 and a lower portion of the hook 430 is hooked to the hook 420, .

The lever 450 is connected to the main body 420 such that one end is connected to the operation handle 480 and the other end is rotatable by the second pin 470 and the loop fixing part 460 is fixed .

When the lever 450 is rotated about the second pin 470 as a rotational center by applying a force pulled downward to the operation handle 430 (refer to (1) in Fig. 4), the other end of the hook fixing portion 460 (Refer to (2) in FIG. 4) until reaching the groove formed in the latching ring 430. As a result, the latching ring 430 rotates about the first pin 440 (see? In Fig. 4), and the latching state with respect to the chain 410 is released (see? In Fig. 4). However, it is needless to say that the structure of the hook unit 230 for releasing the engagement state of the lifeboat 10 with respect to the hook unit 230 is not limited to that described above.

The lifeboat 10 is lifted up by the lifeboat 10 to the hook unit 230 so that the lifeboat 10 is lifted up by the lifeboat 10 when the lifting member of the lifeboat 10 pulls the operation handle 480 to release the hooking- The fastening state is released and is advanced to the water surface along the path provided by the guide rail of the guide rail structure 260.

When the life of the lifeboat 10 is released by releasing the hook unit 230 from the chain 410, the force applied to the movement blocking member 250 is removed, and the movement blocking member 250 is restored to its original shape Will be.

Referring again to FIG. 3, after the chain connected to lifeboat A is separated from the hook unit 230 and the lifeboat A is launched, the boarding person who boarded the lifeboat B connects the lifeboat B and the boarding floor 270 The life of the lifeboat B can be shifted to the center position by releasing the fixed state of the fixing device 235 to allow the lifeboat B to rotate the circular structure 220 by its own weight (refer to FIG. 3 (d)).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
