Description

[Detailed description of the invention] The present invention relates to the invention of a billet overturning table, and aims to provide a turning table capable of safely and quickly overturning and aligning a large number of vertically cast billets in a continuous casting facility or the like. It is something.

Billets cast vertically in continuous casting equipment are charged into a heating furnace and subjected to appropriate heat treatment, and then lifted by a crane and tipped onto an alignment table for inspection, cargo handling, and other handling. It is necessary to arrange them horizontally.

However, the operation of arranging multiple billets suspended in this manner on the sorting table is a huge operation in which each billet weighs several hundred kg or more, and as mentioned above, multiple billets are handled at the same time. Therefore, it is not easy, involves some degree of danger, and is inferior in workability.

In other words, in such work, when multiple billets as described above are hoisted, their bottom ends are usually uneven, and it is generally impossible to align them simply by lowering them. Even if it is easy to roll an object with a circular cross section in the circumferential direction, it is extremely difficult to move the object in the axial direction once it is placed on a pedestal or on the floor. It is clear that this method requires a lot of effort and man-hours.

The present invention has been devised so that a plurality of billets as described above can be smoothly overturned and arranged.

That is, to explain the embodiment of the present invention as shown in the attached drawings, firstly, in the case of lifting by a crane, as shown in Figs. A plurality of hanging ropes 13 are arranged, and the billet 10 is
In this case, the upper end of each billet 10 is wrapped around the upper end of the rope.
A horizontal rod 15 perpendicular to the length direction of each billet is interposed at a slightly upper position than 4, and the billet is lifted.

As described above, each billet 10 to which a hanging rope is connected by the hanging rope wrapping part 14 is suspended in the air at an appropriate inclination. 1
Since the weight ratio of the upper and lower parts of the winding part 14 at 0 is slightly different, it is normal that the weight ratio of the upper and lower parts of the winding part 14 is slightly different, and therefore the lower end position of each billet 10 is also different. By interposing the horizontal rods 15, the horizontal rods 15 are interposed between each hanging rope 13 and the inclined billet head, and in other words, the acting force that tends to straighten the hanging ropes 13 due to the hanging load is applied to the horizontal rods. 15 acts on the head of the billet through the horizontal rod 15, pushing the head of each billet and keeping the angle of inclination substantially constant.

However, a series of billets 1 lifted in this way
In order to perform the overturning operation of 0.10..., in the present invention, a wooden catch 2 is formed on one side of the billet holder 1, and a billet holding plate 3 that is higher than the catch 2 is provided on the other side. It is provided so that it can be raised and lowered with respect to the bearing 6 by a pivot 4, and a sliding plate 5 whose both sides are appropriately curved is attached between the catch seat 2 and the base end of the holding plate 3, and is fixed to the above-mentioned pivot 4. The arm member 7 is pivoted to a rod 9 of an operating cylinder 8, and the operating cylinder 8 has its middle portion pivoted to a pivot seat 16.

That is, in order to receive a plurality of billets that have been lifted as described above, the rod 9 of the operating cylinder 8 is extended as shown in FIG. 2, and the holding plate 3 is tilted horizontally. As shown in FIG. Raise the presser plate 3.

As shown in FIG. 3, once the holding plate 3 has been pulled up and returned to its vertical position, the upper end of the billet is lowered so that the lower end of the series of billets is brought into contact with the catch seat 2. If the upper end of the billet is further lowered from this state, the lower end of each billet 10 will slide upward along the inner surfaces of the sliding plate 5 and the holding plate 3, and eventually the overturned state as shown in FIG. 4 will occur. can be formed smoothly, and each billet 1 is
It is clear that even if the 0's are misaligned in the length direction, they are aligned in an orderly manner.

That is, it is clear that the billets thus fallen onto the catch 2 of the pedestal 1 and the support frame 17 attached thereto are properly aligned, and as shown in FIG. Even when the billets are handled side by side, between the state shown in Figure 2 and the state shown in Figure 3, the lower end side of those billets is separated by the upper billet between the lower billets, as shown in Figure 1. The billet cuts into a single row and acts on the catch plate 2 and the sliding plate 5, and finally, the billet is neatly overturned as a single row billet as shown in FIG. 4.

According to the present invention as explained above, it is possible to overturn a plurality of billets in a precise alignment within a short period of time, that is, billets suspended with their lower ends supported by a catch. In the process of lowering and leveling the billet, the lower end of the billet is constantly pressed against the sliding plate 5 and the holding plate 3, and the billet is aligned and falls down, making it possible to obtain an orderly alignment, which is better than when the worker takes a lot of man-hours to align the billet. A highly accurate falling alignment can be quickly formed, and this type of work that conventionally required at least two to three workers can be efficiently carried out by a single worker, so it is highly effective in practical terms. It's a big idea.

If a trunnion type air cylinder is used as the operating cylinder described above, the presser plate 3 can be supported by utilizing the compressibility of the linear to press the lower end of the billet during the billet falling process as described above. From this point of view as well, it is possible to realize an advantageous operation that causes less damage to the billet and other parts.
