Description

Folding sea hook device {A C-HOOK APPARATUS}

The present invention relates to a sea-hook device for moving the hot rolled and cold-rolled coils produced in a steel mill to a required position in the production process. More specifically, the hook portion of the sea-hook device can be briefly moved when the coils are closely stacked. The coil can be moved after folding and entering the inner coil part of the coil, so that the folding and moving of the coil can be performed smoothly even if the stacking space of the coils is reduced as compared with the conventional sea hook. It relates to a sea hook device.

In general, steel mills produce slabs that have undergone steelmaking, smelting, and refining processes as strips produced through rolling processes, which can be divided into hot rolled and cold rolled coils. In order to move the coil using a seed hook, i.e., a C-shaped seed hook which is supported by the inner winding of the coil, the conventional seed hook is shown in FIG.

That is, as shown in FIG. 1, C of the sea-hook device 120 supported by the connecting piece 122 to the hook 112 of the crane 110 in the inner winding portion 102 of the stacked coils 100. The female seed hook 124 is inserted to perform the movement of the coil 100 by the operation of the crane 110.

By the way, in the conventional sea hook apparatus 120, since the sea hook 124 is C-shaped and fixed, the sea hook 124 is inserted into the inner winding 102 of the coil 100. Since the space between the coils 100 is absolutely necessary, since the coils 100 cannot be densely stacked, a storage space is quite necessary.

In addition, as shown in FIG. 1, when the coils 100 are densely stacked, in order to move the specific coil 100 in the stacked state, the front and rear coils 100 'of the coil 100 ( Since one of the 100 ") must first be moved to an arbitrary place, and then the coil 100 must be moved again, it is inconvenient to load and move the coil, and of course, the work time is also significantly delayed, which leads to production. It is to reduce the productivity of the line.

Accordingly, it would be desirable to manufacture the sea hook of the sea hook device in a folding manner irrespective of the stacking state of the coils, since the stacking and moving of the coil is easy and the stacking space of the coil is reduced.

SUMMARY OF THE INVENTION The present invention has been made to improve the above-mentioned problems. The object of the present invention is to simply fold a hook of a sea-hook device into a coiled inner portion of a coil in order to move the coils in a densely stacked state, and then move them. It is possible to provide a folding type sea-hook device that can efficiently operate a storage space of a coil.

In addition, another object of the present invention, it is possible to smoothly perform a specific coil of the stacked coils without prior movement of the surrounding coil to facilitate the coil input to the product production line using the coil to further improve the productivity of the coil product It is to provide a folding sea hook device.
