Hereinafter, embodiments according to the present invention will be described with reference to the drawings. It should be noted, however, that the embodiments described below are illustrative of one preferred embodiment of the present invention, and examples of such embodiments are not intended to limit the scope of the present invention. The present invention can be carried out in various modifications without departing from the spirit thereof.

1 is an overall configuration diagram of a slab cylinder to which the slab barrel grip detection apparatus of the present invention is applied, and FIG. 2 is an enlarged view of main parts of the slab cylinder shown in FIG. 1.

The slab barrel grip device according to the present invention is installed in the slab barrel main body 10 formed in the shape of tongs and the grip 11 provided at the end of the main body, and the grip 11 of the main body 10 is provided. It is configured with a grip detection device.

The lower side of the main body 10 is fixed using a separate fastening member to replace the grip 11 for picking up the slab.

In addition, a fixing part 12 for fixing the grip sensing device is formed at an end at which the grip 11 of the main body 10 is provided.

In the above, detailed description of the grip and the slab tube will be omitted.

The grip sensing device comprises an operating bar and a spring sensor. The operation bar 20 is formed in the "L" shape. The operation bar 20 has a hole (20a) is formed in the center thereof is coupled to the main body 10 using a separate fastening member rotatably.

The combined operation bar 20 is installed to protrude outward compared to the grip 11.

The spring sensor 30 is fixed to the main body 10 through the bracket 31 on the upper side of the operation bar 20. The position of the spring sensor 30 fixed to the main body 10 is fixed to a position where one side of the operation bar 20 can be in close contact with the spring sensor 30 when the operation bar 20 is rotated.

The lower end of the operation bar is provided with a roller 21 in close contact with the slab (S). The lower end of the horizontal portion of the operation bar is supported by the guide protrusion 12a fixed to the main body 10.

In addition, the rotation of the roller 21 provided in the operation bar 20 is limited by the guide block 40 fixed to the main body 10. The guide block 40 is formed with a groove 41 in which the roller 21 is in close contact.

The operation bar 20 is formed of a conductive material. And, although not shown in the drawings, the spring sensor 30 is electrically connected to the control unit.

 3 is a configuration diagram showing an operation configuration of the slab barrel according to the grip detection device.

In the slab barrel grip device according to the present invention, the respective grip detection devices are mounted on the lower side of both side clamps of the slab barrel. The spring sensor 30 of the grip detection device is connected to the controller 50. Therefore, the spring sensor 30 is supplied with power through the control unit 50.

Apparatus for the slab barrel grip device of the present invention is first placed on the slab by lowering the slab barrel connected to the crane. As described above, when the slab tube is positioned in the slab (S), the slab tube is opened to both sides. At this time, when the crane lifts the slab barrel, the slab barrel is tightened to the inner side and the grip 11 is in close contact with both sides of the slab.

When both grips of the slab are in close contact with the slab, the operating plate 20 provided in the main body 10 is rotated by the slab, and one side of the operating plate 20 is in close contact with the spring sensor 30.

When the operating plate 20 is in close contact with the spring sensor 30, electricity is conducted to the slab (S) by the operating plate 20 mounted on both grips 11 of the slab barrel.

When the operating plate 20 provided on both sides of the slab tube is in close contact with the slab (S) and in close contact with the spring sensor 30 provided on both sides of the slab tube, the control unit 50 is the spring sensor 30 in the control unit 50. While the electricity applied to detect the return of electricity back to the control unit 50 through the spring sensor 30 again through the slab (S) and calculates the resistance value of electricity, although not shown in the drawing is provided in the crane The grip signal is sent to the main controller.

When the grip signal is sent from the control unit 50, the crane is lifted and the desired slab S is moved by the slab barrel. Then move the slab (S) to the desired position and then lower the crane to remove the slab (S) from the slab barrel.

Therefore, according to the present invention due to the grip detection device consisting of the operating bar 20 and the spring sensor 30 for detecting the operation of the operation bar 10 rotatably installed in the main body 10, the slab during operation of the slab cylinder When the operating bar 20 is in close contact with or hit (S) the operating bar 20 is not broken by the operation bar 20 is rotated.

In addition, the operating bar 20 is in close contact with the slab (S) in the slab cylinder is moved state one end of the operating bar 20 is elastically supported by the spring sensor 30, the operation bar due to shaking due to external impact ( 20) is always fixed in close contact with the slab (S).

Therefore, the grip signal is kept constant during the transfer of the slab cylinder so that the slab cylinder does not stop with the slab S mounted in the air.

The embodiment according to the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the technical concept of the present invention.
