Description

Transporting device and method TECHNICAL FIELD {TRANSPORTING APPARATUS AND METHOD}

The present invention relates to a conveying device and method, and more particularly, to a conveying device and method capable of easily crushing a fixation formed on a container while transporting the container.

The molten steel refined in the steel making process is conveyed in a continuous casting process and cast into cast iron. At this time, a ladle is used to transport molten steel. Specifically, a ladle containing molten steel is placed above the tundish of a continuous casting facility, and molten steel in the ladle is injected into the tundish.

When the injection of molten steel is completed, the ladle is recovered from the continuous casting facility using a crane. Slag and residual hot water exist inside the ladle after the injection of molten steel is completed. Therefore, before collecting the ladle, the slag and residual water in the ladle must be discharged to a separate port.

On the other hand, when the slag and residual water in the ladle are discharged to the pot, if the current is fixed on the top of the ladle, it is difficult to discharge the slag and residual water from the ladle. Therefore, before discharging the slag and residual metal from the ladle, the metal chips fixed on the upper part of the ladle must be crushed.

The technology that serves as the background of the present invention is published in the following patent documents.

Specifically, the thickness of the rigid body 500 may be 1 m to 3 m, and more specifically, 2 m. The above-described numerical values are examples for explaining an embodiment of the present invention. The thickness of the rigid body 500 may vary depending on the size of the equipment to which the transport device is applied. Here, the thickness may mean a diameter or a thickness.

Due to the above-described material and thickness, the rigid body 500 may have sufficient strength to support the crushed part 400 without shaking.

The rigid body 500 may extend in the vertical direction, may be disposed to pass through the operation unit 600, and the operation unit 600 and the screw to adjust the elevation height by using the rotation of the operation unit 600 Can be combined.

A plurality of first gears 610 are provided, respectively, and may be spaced apart from each other in a horizontal direction. In this case, the number of first gears 610 may be the same as the number of rigid body shafts 500.

On the other hand, when the first gears 610 are provided as a pair, the direction of forming the thread of the female screw formed in each of the first gears 610 may be different from each other. For example, when a female screw formed on an inner wall of any one of the first gears 610 is formed in a left-handed manner, the other female screw may be formed in a right-handed manner.

The second gear 620 may include a bevel gear. The second gear 620 may be disposed between the pair of first gears 610. The second gear 620 may correspond to the first gear 610 one-to-one.

The rotational force of the second gear 620 is transmitted to the first gear 610 and the direction is changed, and thereafter, it may be used to lift the rigid body shaft 500 in the vertical direction.

Meanwhile, the rotation of the first gear 610 and the second gear 620 for lowering the rigid body shaft 500 is referred to as a forward rotation, and the first gear 610 and the first gear 610 for raising the rigid body shaft 500 2 The rotation of the gear 620 is referred to as reverse rotation.

In order for the first gear 610 to axially rotate around the rigid body shaft 510 and to move the rigid body shaft 510 in the vertical direction, the height of the first gear 610 must be fixed at a constant height.

The elastic body may include a spiral spring formed in a spring shape.

The housing may be mounted at the center of the upper surface of the lower cover 220 or at the center of the lower surface of the upper cover 210. The central axis may be installed in the housing to enable axis rotation around a horizontal direction. Both ends of the central axis may protrude to the outside of the housing, respectively. Both ends of the central shaft may be mounted on a pair of drums 710. The central axis may rotate the drum 710.

One end of the elastic body may be supported on the inner peripheral surface of the housing, and the other end may be mounted on the central axis. When the pair of drums 710 is rotated forward by pulling the wire 720, the central axis rotates forward and the elastic body is deformed, so that elastic force can be accumulated in the elastic body.

When the traction of the wire 720 is released by lowering the bokwon hook 610, the central axis can be reversely rotated while the elastic body is restored. Accordingly, while the pair of drums 710 rotates reversely, the wire 720 may be wound on the outer circumferential surface thereof, and the second gear 620 and the first gear 610 are rotated in reverse to the rigid body shaft 510 Can be raised. The rise of the rigid body shaft 510 by this elastic force may be referred to as a power rise or a forced rise (see FIG. 3).
