The present invention relates to a slab position alignment device for a turnover device, and more particularly, a turnover device for maximizing the production quality of the slab by effectively aligning the position of the slab to prevent the impact and damage generated in the turnover process Slab positioning device for

In general, various foreign substances such as oxide scales are generated on the surface of slabs produced in steel mills and steel mills. These foreign substances cause damage to the slabs, resulting in deterioration of production quality and deterioration of work efficiency in subsequent processes. In order to do so, by spraying a high-pressure mixed gas on the surface of the slab to maintain a uniform surface and at the same time to carry out a scarfing operation to remove the foreign matter.

At this time, two-sided scarfing on the top and front side of the slab should be carried out again after the two-sided scarfing work on the bottom and the rear side of the slab due to the structure of the scarfing device. The turn over device will be used.

This conventional turn-over device is rotated in the upper and lower directions via the hinge shaft (11, 21) in accordance with the operating state of the hydraulic cylinder (13, 23) as shown in Figure 2, but the locking jaw (12) 22 is provided with a pair of turn over devices (10, 20).

That is, as shown in FIG. 3, when the slab A is supplied to the upper portion, the turn over device 10 rotates in the vertical direction by the operation of the hydraulic cylinder 13, and on the other side of the over device 20. In addition, since the hydraulic cylinder 23 rotates in the vertical direction while the slab A is rotated, the positions of the upper and lower surfaces are changed, thereby completing the turnover operation of the slab A.

However, in the conventional turn-over device 10 and 20, the slab A is lowered to its own load in the process of rotating in the vertical direction, and the slab A is hit by the locking jaw 12, thereby causing damage to the surface of the slab A. In severe cases, there is a serious problem of leaving the position.

Therefore, in recent years to solve the above problems,

A first arm rotatably mounted on the base concrete, the first arm being provided with a rotational force from the first cylinder, and having a support jaw on the upper surface of the end of the pin, and installed at a position symmetrical with the first arm. A slab turning device, the slab turning device being rotatably mounted around the slab, the slab turning device being provided by a second cylinder, the slab turning device being turned upside down by a second arm having a support jaw on the upper surface of the pin side end. Gear wheels rotatably mounted at both ends are connected to each other by a power transmission chain with a sprocket wheel, and the gear wheel is equipped with a belt such that an upper transport surface protrudes above the first arm, and one of the gear wheels. Is composed of a sensor which receives the rotational power from the drive motor and has an initial position projecting to the slab side surface portion of the center upper portion and the support jaw respectively. It may bar a "slab turning device having a slab position adjusting structure" of Patent No. 0,474,648 contemplated the arcs.

However, the conventional "slave turning device having a slab positioning structure" can adjust the position of the slab, but the overall configuration is complicated, so that frequent failures easily occur, which has a disadvantage in that the use efficiency and utilization range are extremely limited.

In particular, since the conventional "slab turning device having a slab positioning structure" has a structure for simultaneously adjusting the position of the slab and simultaneously performing the turnover operation, it is necessary to stop the turnover operation of the slab for maintenance. As a result, not only the production efficiency is lowered, but also enormous economic losses are caused by the delay of work.

In addition, the conventional "slab turning device having a slab positioning structure" can adjust the position only when the slab is completely seated on the upper part, and as a result, there is a problem in that it cannot perform an essential function for aligning the slab. .

Therefore, the structure is simple and easy to maintain, which increases the efficiency of use, and the means to maximize the production quality by minimizing the damage of slab generated during turnover work by aligning the slab position efficiently. All are urgently needed.

As such, the present invention has been made to solve the conventional problems as described above,
