There is a curved portion 42 surrounding the edges of the first partition plate 10 and the second partition plate 10'. The curved portion 42 is to prevent the main line 1 or the branch line 3 from being damaged by the sharp cross-sections of the first and second partition plates 10 and 10'. In the present embodiment, a cylindrical rod was installed around the edges of the first and second partition plates 10 and 10' to form the curved portion 42 .

Meanwhile, the screw shaft 36 may be rotated using an electric motor or a hydraulic motor instead of the handle 38 .

Hereinafter, it will be described in detail whether the lifting device according to the present invention having the configuration as described above is used.

In the lifting device of the present invention, any one of the first partition plate 10 and the second partition plate 10 ′ may be mounted on a fixed part of the vessel and used. For example, when the second partition plate 10 ′ is fixed to the fixed part of the ship, the first partition plate 10 side is rotated around the rotation center shaft 30 by the rotation of the screw shaft 36 . In operation, when the first partition plate 10 is fixed to the fixed part of the ship, the second partition plate 10 ′ is operated around the rotational central axis 30 . Accordingly, the first partition plate 10 or the second partition plate 10 ′ is rotated relative to the center of rotation 30 .

In order to lift the original line (1) together with the branch line (3) on which the aquaculture product is attached using the apparatus of the present invention, the original line (1) is moved to the inclined surface (14) of the first and second inclined rollers (12, 2') It should be placed in the space it forms. That is, as can be seen in FIG. 6 , the original line 1 must be passed between the inclined rollers 12 and 12' so as to penetrate the space indicated by A.

For this, the screw shaft 36 must be rotated. In order to rotate the screw shaft 36, the handle 38 or a driving source is operated. As the screw shaft 36 is rotated, the first and second movement guides 34 and 34' should be brought closer to each other. This is because the first rotation lever 20 and the second rotation lever 20' have a 'V' shape. If the first rotation lever 20 and the second rotation lever 20' are formed in a substantially straight line and intersect in an 'X' shape, the first and second movement guides 34 and 34' should be moved away from each other.

When the screw shaft 36 is rotated to bring the first and second movement guides 34 and 34' closer to each other, the first rotation lever 20 and the second movement guide connected to the first movement guide 34 are rotated. The second rotation lever 20 ′ connected to 34 ′ is rotated about the central rotation axis 30 so that the first partition plate 10 and the second partition plate 10 ′ are separated from each other. Accordingly, the gap between the first inclined roller 12 installed on the first partition plate 10 and the second inclined roller 12 ′ installed on the second partition plate 10 ′ is widened. Such a state is shown in FIG. 4 .

In this state, the original line 1 is passed between the first inclined roller 12 and the second inclined roller 12', and between the upper end of the first partition plate 10 and the second partition plate 10'. position, and rotate the screw shaft 36 in the opposite direction to the previous one.

The screw shaft 36 is rotated so that the first inclined roller 12 and the second inclined roller 12' are adjacent to each other with a predetermined distance therebetween. 6 shows a state in which the first inclined roller 12 and the second inclined roller 12' are adjacent to each other with a predetermined distance therebetween. The main line (1) is located in a 'V'-shaped space formed by the inclined surface 14 of the first inclined roller 12 and the second inclined roller 12', and the branch line (1) hanging from the main line (1) 3) is in a state capable of passing through the space between the opposing surfaces 16 of the first inclined roller 12 and the second inclined roller 12'.

At this time, the rotation of the handle 38 may proceed until the adjustment bolt 25 of the first stopper 24 and the second stopper 24 ′ come into contact with each other. When the second stopper 234' comes into contact with the adjustment bolt 25, the rotation between the first rotation lever 20 and the second rotation lever 20' is no longer made and the screw shaft 36 ) and the screw portions of the movement guides 34 and 34' are kept in close contact with each other. The degree to which the adjustment bolt 25 protrudes from the first stopper 24 is set in advance in consideration of the thickness of the branch line 3 . In this way, since the screw shaft 36 can be rotated until the adjusting bolt 25 comes into contact with the second stopper 24', the operator uses the first and second partition plates 10, 10'), the handle 38 only needs to be continuously rotated until the handle 38 is rotated.

In the state of FIG. 6, when the original line 1 is pulled by a separate driving means, the branch line 3 in the original line 1 moves between the first inclined roller 12 and the second inclined roller 12'. will go through The inclined surfaces 14 of the first inclined roller 12 and the second inclined roller 12 ′ guide the original line 1 . The inclined surface 14 also serves to guide the branch line 3 to smoothly enter between the first inclined roller 12 and the second inclined roller 12'.

On the other hand, the original line (1) is pulled and in the process of moving the branch line (3) and the aquaculture, the original line (1) or the branch line (3) may collide with the partition plates (10, 10'). A curved portion 42 is formed around the edges of the partition plates 10 and 10 ′ to prevent damage to the original line 1 or the branch line 3 .

And, the lifting device of the present invention may be installed in a plurality of one ship, any one of them may have a driving source for pulling the original line (1). That is, while connecting the drive shaft of the drive source to the drive shaft connection part 18, the drive source is mounted on the mounting barrel 19, and the first and/or second inclined rollers 12 and 12' are rotated by the drive source to rotate the original line ( 1) can be pulled. Of course, the first and second inclined rollers 12 and 12 ′ may be rotated by the force of movement of the original line 1 while serving as a guide for the original line 1 .

In the above, even though all components constituting the embodiment of the present invention have been described as being combined or operated in combination as one, the present invention is not necessarily limited to this embodiment. That is, within the scope of the object of the present invention, all the components may operate by selectively combining one or more.
