Description

Rotation angle adjustable drive device and slag residue removal device including the same {Driving Device and Shear Beam having The Same}

The present invention relates to a rotation angle adjustable drive device and a slag residue removal device including the same, and more particularly, since the drive unit driven at a predetermined rotation angle does not use an (external) drive source such as a conventional cylinder, Rotation angle adjustment type drive device which is useful to prevent the cost incurred due to equipment damage and maintenance of damaged equipment by the maintenance of damaged equipment, and to operate the shear beam to remove the residues of slabs such as slab cutting. It relates to a cast residue removal device comprising.

In general, the slabs produced through the continuous casting process is made of slabs by cutting to a certain length, such a slab cut having a considerable thickness using a torch using oxygen and gas.

Therefore, the slab provided by slab cutting generates residues such as bur or torch slag, in particular around the cut surface, and such residues are mainly caused by poor quality when put into the post-process of the slab from which the slab is cut. As it becomes a factor, it must be removed.

By the way, there is a limit to the manual removal of the residue on the slab by the operator, in particular, it is currently impossible to remove the residue by hand due to the increase in the line speed for improving productivity.

Thus, a shear beam facility that removes the residue of the slab is used to remove the residue of the slab.

For example, FIG. 1 shows a shear beam apparatus 100 for known residue removal. That is, the upper and lower sheer beams 130 and the lower sheer 150 are provided on the upper and lower sides of the apparatus frame 110, respectively, and the upper sheer beam 130 is connected to the vertical driving cylinders 132 on both sides of the frame. The upper sheer beam 130 is raised or lowered to match the slab entering the device.

On the contrary, the lower sheer beam 150 is connected to a vertical drive cylinder 170 vertically installed at the outer side of the frame and a shear beam drive shaft 152 connected to the rotation ring 174 connected to the connection beam 172.

Accordingly, the connecting beam rotates the drive shaft integrally with the rotary ring according to the operating stroke of the vertical drive cylinder.

Meanwhile, although schematically illustrated in FIG. 1, the bodies of the upper sheer beam 130 and the lower sheer beam 150 are elongated cylindrical bodies, and several knife units 134 and 154 are arranged in such a body. It is installed.

At this time, since the conveying height of the slab S moving along the slab feed roller 102 of the shear beam device 100 is constant, the upper shear beam 130 may remove the residue of the slab thickness or the front and rear surfaces of the slab. In order to ascend and descend, the lower sheer beam 150 controls the slab contact of the knife unit 154 while being rotated and driven since the contact point with the slab is always constant.

Meanwhile, pneumatic lines L1 and L2 for supplying air pressure to the knife units 134 and 154 are connected to the drive shafts of the upper and lower shea beams through the inner space of the shea beam body.

For example, known knife units are provided in a pneumatically self-actuated cylinder manner, and although not shown by reference numerals, there is a built-in spring for cushioning the knife contact of the slab.

However, in the conventional shear beam apparatus 100 shown in FIG. 1, a vertical drive cylinder vertically installed on the outer side of the frame is mounted on the rotation ring 174 assembled to the drive shaft 152 of the lower shear beam 150 that is rotated in particular. Since the 170 is connected to the connecting beam 172, a substantial load is applied to the cylinder 170 and the connecting beam and the rotating ring connection during repeated rotational driving of the actual lower sheer beam 150, thereby easily breaking or disconnecting the connection. There was a problem that the dismantling, such as bolts and nuts for.

For example, because the lower sheer beam 150 is cut in the knife cap portion of the knife unit 154 upon removal of the cut tongue on the slab. It is to rotate, for example, tilting, in order to prevent the cutting or the like from being caught or attached to the knife unit by rotating.

Therefore, in the conventional case, since the rotary drive of the lower sheer beam 150 is implemented by using the outer cylinder 170 as described above, the repetitive tilting or tilting (rotation) angle of the lower sheer beam is implemented. In addition, excessive needles (loads) are applied to the connection beams and the connection parts of the rotating ring and the cylinder rod, and parts such as bolts and nuts are dismantled or broken.

In addition, as shown in Figure 1, when implementing the tilting (rotation) of the lower shea beam using a cylinder, since one-way tilting is implemented, the problem that the residue removed in the knife unit or the shear beam body portion is caught It remains.

Accordingly, the applicant of the present invention proposes a rotation angle adjustable drive device for the rotational drive of the shea beam, and transmits the rotational force directly to the shea beam without using a conventional cylinder and its connecting parts while implementing both directions tilting As a result, the present invention has been proposed to solve the problems caused by equipment damage or maintenance.
