Description

Coil tilting device {COIL TILTING DEVICE}

The present invention relates to a device for tilting a coil such as a steel coil or a magnesium coil. More specifically, the present invention relates to an apparatus for tilting a coil in a lying state to a coil in an erect state.

Coils such as steel coils and magnesium coils are manufactured through various processes and have different physical properties depending on heat treatment conditions.

1 schematically shows a process of manufacturing a coil and putting it into a heat treatment furnace.

The coil 120 is obtained by rolling the slab or cast coil 110 to a desired plate thickness such as 0.4 to 0.5 mm thickness, cooling by air cooling or water cooling, and then winding. The obtained coil 120 is put into the heat treatment furnace 130 and subjected to heat treatment to obtain desired physical properties.

When the coil 120 is initially wound, the axis x of the coil is in a horizontal direction and is in a lying state.

When the coil 120 is put into the heat treatment furnace 130, the axis (x) of the coil is in a vertical direction, that is, an ETS (eye to sky) state, which means a state in which the eyes (a) of the coil are erected toward the top. Need to be tilted to The reason is that there is a risk of buckling in the inner winding portion of the coil 120 when the coil axis x is put into the heat treatment furnace in a horizontal direction.

In order for the axis of the coil to tilt in the horizontal direction and the axis of the coil in the vertical direction, a method in which an operator winds the coil with a rope and operates a crane fastened with the rope is mainly used.

2 shows an example of tilting a coil using a rope.

The rope 210 includes a portion surrounding the coil 120 and a portion for fastening to the crane 220. Wrapping the coil using the rope 210 is performed by the operator, and the operator's force is also required to control the tilt of the rope when the crane is operated.

On the other hand, the coil winding temperature is often not at room temperature but at a high temperature of 100°C or higher, and the coil temperature is not as low as 50 to 100°C even when the coil is tilted. Accordingly, there is a risk of a safety accident when the worker wraps the coil with a rope. In addition, there is a problem in that workability is deteriorated because the force of the operator is also required to control the tilt of the rope when the crane is operated.

The problem to be solved by the present invention is to provide a mechanical coil tilting device by breaking away from the conventional coil tilting method using a rope.

In particular, the problem to be solved by the present invention is to provide a coil tilting device that is safe and does not require a lot of space for coil tilting.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention that are not mentioned can be understood by the following description, and will be more clearly understood by examples of the present invention. In addition, it will be easily understood that the objects and advantages of the present invention can be realized by the means shown in the claims and combinations thereof.

A coil tilting apparatus according to an embodiment of the present invention for solving the above problem includes a coil hook, a pin member, and a lift arm member disposed in the inner winding portion of the coil. In addition, a link member and/or a crane hook may be further included.

The coil hook includes a first coil hook and a second coil hook. The pin member is disposed between the first coil hook and the second coil hook, and is coupled to the first coil hook and the second coil hook, respectively. The lift arm member is coupled to an end of the pin member so that the pin member is rotatable.

The pin member and the first coil hook may be coupled through a first link member, and the pin member and the second coil hook may be coupled through a second link member.

In addition, the lift arm member may include or be coupled to a crane hook.

Through this, when the lift arm member is lifted by the crane, the pin member rotates, whereby the coil may be tilted in the rotation direction of the pin member.

The position of the pin member to which one end of the first link member is coupled is a position lower than the position of the first coil hook to which the other end of the first link member is coupled, and the position of the pin member to which one end of the second link member is coupled May be a position lower than the position of the second coil hook to which the other end of the second link member is coupled. Through this, the first link member and the second link member may form a substantially "V"-shaped cross section.

A position of a pin member to which one end of the first link member is coupled and a position of a pin member to which one end of the second link member is coupled may be different. As another example, the position of the pin member to which one end of the first link member is coupled and the position of the pin member to which one end of the second link member is coupled may be the same.

The angle formed by the first link member and the second link member may be variable.

When the lift arm member is lifted, an angle formed by the first link member and the second link member may be changed.

When the first link member and the second link member are used as unit link members, there may be a plurality of unit link members. By arranging a plurality of unit link members, the effect of preventing the coil hook and the pin member from being separated from the coil during lifting of the lift arm member can be further improved.

Each of the first coil hook and the second coil hook may have a'C'-shaped cross section.

The lift arm member has a first portion and a second portion bent at the first portion, and an end of the first portion is coupled to the pin member, and a crane at a position where the first portion and the second portion intersect. Hooks can be combined.

The crane hook may be coupled to the second part of the lift arm member to be changeable in position.

The coil tilting apparatus according to the present invention includes a coil hook disposed in an inner winding portion of the coil, a pin member coupled to the coil hook, and a lift arm member coupled to the pin member so that the pin member is rotatable.

Through this, when the lift arm member is lifted by the crane, the pin member rotates, whereby the coil may be tilted in the rotation direction of the pin member.

The coil tilting device according to the present invention is safe because the operator does not intervene in the tilting process by lifting mechanically, and also performs coil tilting using a coil hook disposed in the coil inner winding, thereby saving a lot of space for coil tilting. There is an advantage that is not required.

3 shows an example of a coil tilting device according to an embodiment of the present invention. Fig. 3(a) shows a state before the lift arm member is lifted, and Fig. 3(b) shows a state after the lift arm member is lifted.

Referring to FIG. 3, the coil tilting apparatus according to the present invention includes a coil hook 310, a pin member 320, and a lift arm member 340. In addition, the coil tilting apparatus according to the present invention may further include a link member 330 and/or a crane hook 360.

The coil hook 310 includes a first coil hook 310a and a second coil hook 310b.

Each of the first coil hook 310a and the second coil hook 310b may have a'C'-shaped cross section. Each of the first coil hook 310a and the second coil hook 310b may have a'C'-shaped cross section through a combination of different members. In the'C'-shaped cross section, two horizontal portions are in close contact with the side of the coil, and one vertical portion is in close contact with the inner winding portion of the coil along the width direction of the coil.

The first coil hook 310a and the second coil hook 310b are disposed in close contact with the inner winding portion of the coil, respectively. Preferably, the first coil hook 310a and the second coil hook 310b are disposed to face each other.

The pin member 320 is disposed between the first coil hook 310a and the second coil hook 310b. The pin member 320 is coupled to the first coil hook 310a and also coupled to the second coil hook 310b.

The lift arm member 340 is a part that is lifted by the operation of the crane. The lift arm member 340 is coupled to an end of the pin member 320 so that the pin member 320 is rotatable. The joint member 350 of the lift arm member 340 and the pin member 320 is both the lift arm member 340 and the pin member 320 so that relative rotation between the lift arm member 340 and the pin member 320 is possible. And a common axis passing through.

As shown in (a) of Figure 3, before the lifting of the lift arm member 340 is started, the pin member 320 and the lift arm member 340 are at an angle of 90 degrees. On the other hand, as in the example shown in Figure 3 (b), when the lift arm member 340 is completely lifted and the coil is in a complete ETS (eye to sky) state, the pin member 320 and the lift arm member 340 are It has a 180 degree angle. This corresponds to a result of relative rotation between the lift arm member 340 and the pin member 320 due to the lifting of the lift arm member 340. In the case of the present invention, by lifting of the lift arm member 340, the pin member 320, the coil hook 310 and the coil sequentially coupled to the lifting arm member 340 rotate together, so that the coil is tilted. .

As in the example illustrated in FIG. 3, the pin member 320 and the first coil hook 310a are coupled through the first link member 330a. Likewise, the pin member 320 and the second coil hook 310b may be coupled through the second link member 330b.

At this time, the position of the pin member 320 to which one end of the first link member 330a is coupled is a position lower than the position of the first coil hook 310a to which the other end of the first link member 330a is coupled, and the second The position of the pin member 320 to which one end of the link member 330b is coupled may be a position lower than the position of the second coil hook 310b to which the other end of the second link member 330b is coupled. Through this, the first link member 330a and the second link member 330b may form an approximately “V”-shaped cross section.

An angle formed by the first link member 330a and the second link member 330b forming an approximately “V”-shaped cross section may be variable. More specifically, when the lift arm member 340 is lifted, the angle formed by the first link member 330a and the second link member 330b may be changed. That is, the angle θ1 formed by the first link member 330a and the second link member 330b before the lift arm member 340 is lifted as in FIG. 3(a) and FIG. 3(b) After the lift arm member 340 is lifted, the angle θ2 formed by the first link member 330a and the second link member 330b may be different from each other. More specifically, as the lift arm member 340 is lifted, the pin member 320 is also subjected to force toward the lift arm member 340, and accordingly, the first link member 330a and the second link member 330b are formed. The angle can be increased (θ1<θ2).

In addition, referring to FIG. 3, the position of the pin member 320 to which one end of the first link member 330a is coupled and the position of the pin member 320 to which one end of the second link member 330b is coupled may be different. I can. However, it is preferable that the first link member 330a and the second link member 330b have a symmetrical shape based on an axis along the width direction of the coil.

As another example, the position of the pin member 320 to which one end of the first link member 330a is coupled and the position of the pin member 320 to which one end of the second link member 330b is coupled may be the same. In this case, a portion of the first link member 330a and the second link member 330b, more specifically, a portion coupled to the pin member 320 overlap.

Also, referring to FIG. 3, two first link members 330a and two second link members 330b are disposed. That is, when the first link member 330a and the second link member 330b are used as unit link members, a plurality of unit link members may be disposed. When the number of unit link members is more than one, the fastening force between the coil hook 310 and the pin member is greater. Accordingly, when the lift arm member 340 is lifted, the coil hook 310 and the pin member 320, which have to withstand the load of the coil, can be prevented from being separated from the coil through a higher fastening force.

On the other hand, in order to hang the lift arm member 340 on the hook of the crane, the lift arm member 340 may include a crane hook 360 or may be combined.

Meanwhile, the lift arm member 340 may have a first portion 340a and a second portion 340b bent from the first portion 340a. The first part 340a and the second part 340b of the lift arm member 340 may have an integral structure or may be a combination of two or more structures. The end of the first part 340a is coupled to the joint member 350. Since the pin member 320 is also coupled to the joint member, the end of the first portion 340a of the lift arm member 340 may be regarded as a portion coupled to the pin member 320. In addition, the crane hook 360 may be coupled to a position where the first portion 340a and the second portion 340b of the lift arm member 340 intersect.

The crane hook 360 may be coupled to the second part 340b of the lift arm member to be changeable in position. To this end, a guide groove 345 through which the crane hook 360 can move may be formed in the second part 340b of the lift arm member. When the lift arm member 340 is lifted, the crane hook 360 may be positioned toward the first part 340a of the lift arm member 340 according to a change in the center of gravity. As another example, before lifting of the lift arm member 340, the crane hook 360 is located at a position far from the first part 340a of the second part 340a of the lift arm member 340 for the center of gravity and safety. And, immediately before the lifting of the lift arm member 340 starts, the crane hook 360 may be positioned at the intersection of the first part 340a and the second part 340b of the lift arm member 340.

As another example, the crane hook 360 may be fixedly disposed at an intersection of the first portion 340a and the second portion 340b of the lift arm member 340.

Thereafter, the pin member 320 is disposed between the first coil hook 310a and the second coil hook 310b. Thereafter, the pin member 320 and the first coil hook 310a are connected with the first link member 330a, and the pin member 320 and the second coil hook 310b are connected with the second link member 330b. do.

Thereafter, the end of the pin member 320 is coupled to the joint member 350 having a common shaft, and the lift arm member 340 including or coupled to the crane hook 360 is coupled to the joint member 350. The pin member 320 may be disposed inside the common shaft of the joint member 350, and the lift arm member 340 may be disposed outside the common shaft of the joint member 350. Conversely, the lift arm member 340 may be coupled to the inner side of the common shaft of the joint member 350, and the pin member 320 may be coupled to the outer side of the common shaft of the joint member 350.

Thereafter, the hook of the crane is hooked on the crane hook, and the lift arm member 340 is lifted by operating the crane.
