Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a damino storage device in continuous casting equipment.

In continuous casting equipment, the dummy bar on the conveyor roller table is separated from the slab, lifted to the casting deck side and placed on the gummy car, where it is kept on standby for the next use. Recently, when lifting a die i,-1<, which is being transported in a horizontal position on the surface of a transport roller table, a device is used to lift the die i, -1< in a non-guided state while changing the direction of its axis vertically. According to this type, there is no need to provide an intermediate guide device that can swing or go up and down between the casting deck and the conveyor roller table (from 1ξ to It has the advantage of not requiring a large amount of power to move the dummy bar, and also eliminating the need for a complicated mechanism and operation for transferring the dummy bar from the intermediate guide device force λ to the dummy bar.
J There is a problem.

In other words, if the lifting device malfunctions or there is an operational error, the die separated from the slab cannot be removed from the conveyor roller table, and casting must be stopped.
Unforeseen circumstances arise. Even if the hanging device operates normally, the hanging hook may not be reliably engaged with the dummy bar side locking pin due to bending or twisting of the hanging hook.

The present invention provides a gummy bar storage device for continuous casting equipment that can solve the above problems, and one embodiment thereof will be described below with reference to the drawings.

This causes the hook [(48A)
is actually engaged with the hanging locking pin, and thus the dummy bar (b) is! f! As shown in Figure 8, it can be lifted with its axis in the vertical direction. At the time of B, the dummy bar (2) is guided by the guide roller (3) and bent, and the direction is changed upward from here. The lifting of the die i-t<4 during the subsequent direction change is prevented by the separation presser roller (to). After the dummy bar head (11!A) meets the final pinch row #(1) t'il, the dummy bar separating device (1) is activated and the dummy bar head (11!A) is separated from the slab (b). This separation was carried out by operating the power cylinder to move the sliding iris upward, as shown in the temporary line in Figure 12, and setting the dummy bar width guide to the bank guide position, and then moving the dummy bar width guide to the shore guide position. to forgive,
8. Due to the operation of the power cylinder, @Figure 1 solid line, No. 8
As shown in the figure, move the swinging frame up and move the dummy bar head (1!A) Im together with the transport roller table (
2) Release upward from the side, whereby the slab passes under the chain moving frame block and is guided to the conveying roller table (2). Also, the dummy par is separated from the swinging frame (goods) and becomes completely suspended. @ When the dummy par is lifted 14 as shown in Figure 1, Intention 11, Figure 8, and Figure 9, the dummy pa fall prevention device (5) is activated and the wedge roller (
86m) (11b) is the guide member (8ia) (15b)
and dummy pa (b) are pushed into IIIk. Also, when it is lifted up to the maximum, the rear end of the dummy pa (2) is located between the movable guides (b, a) (51b) as shown in @10WJ. In this state, the roller chain of the tick-baka (II) is activated. and engage the lifting dog with the delivery locking bin. This engagement is stopped when the dummy pad (2) is slightly lifted, and the hook is released! The lifting of the dummy pa (b) by 1 (48 mm) is released.Then, the worm jack is operated to retract the driven sprocket as shown by the imaginary line in Fig. IIs. Then, the hanging hook will separate from the dummy idiot (8) and the chain will be slightly extended.
This lifting hook moves diagonally downward with respect to the lifting locking don, and completely deviates from the movement path of the dummy pa. Then operate the roller chain again,
While hoisting the dummy pad (2), the direction is changed horizontally again and the dummy pad (2) is stored on the dummy pad (8). At this time, since the dummy par is guided by the movable guide (59) (51b), it can be stored on the dummy par (8) without shifting laterally. When this storage is nearing the end, the movable guide (5s
a) Move (61b) down to the non-guide position to allow passage of the wide dummy barhead (1!A). Note that by connecting both brackets @l14fIl via the pin and the ring, the upward movement posture of the swing frame (2) is maintained even though the power cylinder (2) is free.

As mentioned above, the bar (2) is moved onto the swinging frame body, and the lifting locking bin is attached to the hook (4jlA).
), and as shown in the imaginary line in the hsmlx diagram, the lifting device (7) was activated due to a failure or forgetting to operate it. ), tp>, e→, it moves together with the Mukuro dummy par. At the position (c), the dummy pa (b) has already been separated from the slab (2), and the swinging frame (b) moves upward as shown in the imaginary line.
The dummy trout is completely lifted onto the swinging frame body 2 by the rod placed on the hanging hook. This allows the lifting device φ
Although the dummy roller did not operate, the intended purpose of having the dummy roller remove it from the transport roller table (2) was achieved. At this time, the locking protrusion of the dummy bar reverse fall prevention device W (2) engages with the delivery locking bin. Thereafter, the dummy paddle (2) supported by the swinging frame can be lifted by opening the repair 1 operation of the lifting device (7).

In addition, even if the lifting device (7) fails from the beginning and the lifting hook cannot be positioned within the space, the same effect will occur, and when lifting after repairs, the lifting hook will need to be replaced by other equipment, human power, or a wire. engage the locking bottle cap for lifting.

According to the present invention described above, when the dummy cannot be lifted due to a malfunction or operational error in the lifting device, the dummy can be temporarily stored in the Furafuno f-device and removed from the transport roller table. Therefore, casting can be carried out as specified without stopping.

In addition, the hanging hook of the hanging device has a posture correction device installed on the flapper device side, which makes it easy to reduce the bending and twisting force of the chain.Although it is a non-guide hanging type, it is always kept in a constant direction of 1m @ L. You can wait at
The engagement with 1< can always be performed reliably.
