FIG. 4 is a flowchart illustrating a process of salvaging non-mooring using a non-mooring lifting device according to an embodiment of the present invention.

4, a non-mooring lifting device 10 using an automatic shackle is installed on a deck such that a hollow portion formed at the center of the lower frame 120 is positioned above a lifting hole (not shown) of the deck.

The first and second cylindrical drums 310a and 310b are rotated by the drum motor 330 so that the first and second wires 320a and 320b are released and the support member 370 passes through the lifting hole And is lowered into the cargo loading chamber. (S 10)

The non-moorings S in the cargo loading chamber are tied by the first fastening bands 382a and the second fastening bands (not shown) in the longitudinal direction thereof, ). (S 20)

A first wire 320a is fastened and fixed to a first shackle 384a connected to the first fastening band 382a and a second wire is connected to a second shackle (not shown) connected to a second fastening band 320b are fastened and fixed. (S30)

In this state, as the first and second cylindrical drums 310a and 310b are rotated in opposite directions, the first and second wires 320a and 320b are wound and the supporting member 370 is raised. (S40)

As the support member 370 is lifted up, the upper end of the non-mooring passes through the lifting hole and enters the hollow region of the housing box 420, as shown in Fig. (S50)

When the upper end of the non-mooring enters the hollow region of the storage box 420, the driving of the drum motor 330 is stopped and the first wire 320a is drawn from the first shackle 384a and the second wire is pulled from the second shackle (not shown) And releases the second wire 320b. (S60)

Thereafter, the drum motor 330 is driven again to further lift the non-flow S placed on the receiving member 370 so that the non-flow S passes through the lift hole. (S 70)

After the non-flow S is passed through the lifting hole, the rotating member 440 rotates the storage box 420 so that the non-flow S contained in the storage box 420 is horizontally laid. (S 80)

In a state in which the storage box 420 is rotated, the worker takes out the non-mooring S from the storage box 420 and releases the first fastening band 382a and the second fastening band (not shown) After proceeding (S90), the non-mooring (S) is placed in a separate rack and arranged. (S100)

Then, when the unbalanced (S) sorting is completed, the housing box 420 is rotated by the rotating member 440 and returned to the initial position. (S 110)

At this time, the non-mooring lifting device 10 using the automatic shackle descends the wires 320a and 320b and the receiving member 370 again through the lifting holes, and through the repetition of the above- Continuously lift the mooring to the top of the deck.

On the other hand, when an appropriate amount of non-mooring (S) is placed at a specific position on the deck, the upper frame (160) may be rotated to place the non-mooring (S) at another position on the deck. Therefore, the non-mooring lifting device according to the present invention has an advantage that the non-mooring lifting device can be placed at a plurality of locations around the non-mooring lifting device.
