The present invention relates to a magnetic pole assisting device for a coil hoisting apparatus, and more particularly, when a coil, which is a heavy object wound in a cylindrical shape such as a hot coil, is lifted and loaded in a predetermined place, magnetic force can be applied to the coil in a larger area. It relates to a magnetic pole auxiliary device for a coil hoist.

Generally, in steel mills or steel mills, a hoist is used to lift a metal product, such as an iron plate, a hot coil, etc. by magnetic force, and load it in a predetermined position.

The hoist is a magnet or electromagnet is installed in the frame, the magnetic pole of the magnet or electromagnet is exposed to the lower part of the frame to attach the coil to the transfer.

One example of the hoist is a frame 51 which is a magnet body connected to the lift drive unit 50, as shown in FIG. 5, and a pole 52 which is installed on the frame 51 and to the outside. The exposed magnet assembly (not shown) and the magnetic poles connected to the magnetic poles 52 are formed to attach the coils C, and move along the diameter of the coils. And a fold shoe assembly 54 composed of a SHOE 53.

In addition, the above-described pole assembly 54 is moved by a ball screw (not shown) installed outside the frame 51 and rotated by the motor M and the motor M. FIG.

That is, since the curvature is changed to match the diameter of the coil C while the poles 53 are moved by the driving of the motor M, the coil C may be in close contact with the coil C regardless of the change in the diameter of the coil C. As it is, the lifting drive unit 50 is to lift and transport it to a predetermined position.

Since the close contact between the coils C and the poles 53 is formed so that the ends of the respective poles 53 are inclined at an angle, the area of the coils C is as large as possible regardless of the diameter of the coils C. Configured to contact.

However, as described above, the ends of the poles are formed to be inclined at a predetermined angle so as to be in close contact with the coils, thereby increasing the contact area between the coils and the poles even when the magnetic force of the hoisting machine is increased. Since the amount of magnetic flux leaking is increased, the size of the magnetic flux cannot be increased according to the coil, and thus there is a problem in that the lifting force due to the magnetic force is limited.

That is, when constructing the above-described polish assembly, the lower end of the polish can no longer be configured due to the movement of the polish, etc., so that the end angle of the polish is formed so that the coil and the polish have the maximum contact area. There is a limit to increasing the ground area between the pole and the coil.

Accordingly, an object of the present invention is to solve the above problems, and is effectively applied to the coil lifting by intercepting the multiple poles of movement and enclosing the outer portion of the coil, increasing the attachment area, and blocking the leakage magnetic flux. An object of the present invention is to provide a coil hoisting stimulation auxiliary device capable of improving the hoisting force for hoisting a coil.

In order to achieve the above object, the present invention provides a frame that is a magnet body that is moved by a lift drive unit, a magnet assembly that is installed on the frame and the magnetic pole is exposed to the outside, and the magnet is connected to the magnetic pole while being magnetized. In the magnetic pole assisting device for a coil hoist comprising a pole assembly composed of a plurality of poles are formed to be attached and the curvature is changed while moving in accordance with the diameter of the coil,

It includes an extension skirt of a predetermined length is coupled to the pole located at the bottom of the pole assembly by a hinge means and formed to be bent in accordance with the curvature of the coil, and configured to be applied to the coil by applying a magnetic force from the pole; It is characterized by.

1, 2, and 3 are front, cross-sectional, and exploded perspective views illustrating a magnetic pole assisting device for a coil hoist according to the present invention, and is coupled to and rotated by a hinge means to a pole 53 positioned at the bottom of the pole assembly 54. In addition to the material, it is configured to be bent in accordance with the curvature, and is composed of an extension skirt 1 of a predetermined length configured to be attached to the coil by applying a magnetic force from the fold shoe 53.

That is, as the fold shoe 53 moves, the extension skirt 1 is interlocked, and the extension skirt 1 is bent freely to be in close contact with the outer circumference of the coil C to be magnetically attached.

The hinge means includes a rotating groove 2 formed on the bottom surface of the fold shoe 53, a hinge bracket 4 formed on both sides of the rotating groove 2 and having through holes 3 formed therein, and the rotating groove. Inserted portion (6) formed in the upper end of the expansion skirt (1) and inserted into the (2) and the through hole (5) and the through hole (3, 5) is inserted into the insertion portion (6) It consists of a rotating shaft (7) which serves as the center of rotation.

Of course, the rotary shaft 7 is press-fitted or fixed at both ends by welding or the like so as not to be easily removed from the through holes 3 and 5.

As shown in FIGS. 2 and 3, the extension skirt 1 is configured such that a plurality of skirt members 8 can be combined by rotating means to bend freely at a predetermined curvature. Coupling grooves 9 formed at the lower end of each skirt member 8, Through-holes 10 formed in the side portions of the skirt member 8 located on both sides of the coupling groove 9, and the coupling groove ( 9 is inserted into the engaging projection 12 protruding on the upper end of the skirt member 8, the through hole 11 is formed so as to be inserted into the through holes (10, 11) to freely open each skirt member (8). It consists of a rotating shaft 13 to move.

That is, the respective skirt members 8 can be rotated about the rotation axis 13, and as a result, the extension skirt 1 can be bent at a predetermined curvature to be in close contact with the coil C to apply magnetic force. Will be.

Referring to the effects of the present invention as described above, in order to lift and move the coil (C) by the hoist, the lifting drive unit 50 is operated in the place where the coil (C) is moved to move the hoist.

At this time, the pole assembly 54 of the hoisting machine is a state in which the hoist assembly 54 is reversed by a driving means (not shown), and in this state, the hoisting machine descends to the coil C side.

When the hoist is lowered to the coil C, the middle of the frame 51 contacts the coil C, and a predetermined sensor detects this to operate the motor M, and the pole 53 by the motor M is described. ) Are moved to the coil (C) side.

When the pole shoes 53 are moved to contact the coil C, the extension skirt 1 installed on the lowermost pole shoe 53 is in close contact with the coil C and the ground of the coil C and the pole shoe 53 is fixed. The area can be expanded.

In this case, since the plurality of skirt members 8 are rotatably coupled to each other, the expansion skirt 1 may be in close contact with the outer circumferential surface of the coil regardless of the curvature of the coil C.

That is, only by installing the extension skirt 1 which is a very simple structure, it becomes possible to increase the magnetic screen area which contacts the coil C and raises the coil C. FIG.

Of course, when the poles 53 are in contact with the coil C, the magnet assembly is attached to the coil C while magnetizing each of the poles and the extension skirt 1 in the magnet assembly. (1) uses a material that is easily magnetized.

As described above, the present invention installs an extension skirt that is bent and contacted according to the coil curvature in the lowermost shoe in the coil hoist equipped with the pole assembly attached to the coil while slidingly moving, thereby increasing the contact area with the coil and thereby the coil. There is an advantage to improve the power of lifting.
