Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a dummy bar storage device for a continuous casting machine.

(Problems of the Prior Art to be Solved by the Invention) Conventionally, in continuous casting machines, a roller table that can be tilted up and down is provided above the slab passage, and one end of this roller table is moved onto the slab passage by a winch. , a dummy bar storage device was used in which the dummy bar was pulled up by a separate winch on a roller table.However, in this conventional device, the dummy bar was stored in a straight line, and a winch was installed above the dummy bar storage space. Because of the installation of
As shown in Japanese Utility Model Publication No. 159154 and Japanese Utility Model Application Publication No. 55-171459, a trolley that can be moved and installed from the side is provided on the slab passage, and a dummy par winder equipped with a dog for hooking the dummy bar tail is mounted on the trolley. One idea is to provide a take-up drum and store a dummy bar around the drum's outer periphery. However, in this conventional device, if the dummy bar is long, it is necessary to increase the diameter of the storage drum, and the entire device becomes bulky. Large-diameter drums require production and handling, so equipment costs are high. After hooking the dummy part tail with a dog installed inside the drum.

Since the drum is rotationally driven, the wiring and piping to the decorative threads and the dog actuating cylinder are complicated, making maintenance difficult. In addition, there were many problems, such as difficulty in maintaining the dummy bar while the drum was in a state where the outer periphery of the drum was stored.

(Object of the Invention) The present invention was devised to solve the above-mentioned conventional problems, and an object of the present invention is to provide a dummy par storage device for a continuous casting machine that is compact and has a simple structure that can be manufactured at low cost. purpose.

(Structure of the Invention) The dummy par storage device in the continuous casting machine I of the present invention includes:
A trolley that can be moved and installed from the side is installed on the slab passage,
The trolley is equipped with a U-shaped roller table that is laid down sideways, and a dummy bar pulling arm that can be rotated in forward and reverse directions by a drive device is provided within the circular arc portion of the roller table.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a mold, and 2 is a curved part and a horizontal part that are composed of a support roll 3 and a roller table 4 arranged in the direction of drawing out the slab. 5 is a chain link type dummy bar, 6 is a slab, and the slab 6 is pulled out of the mold 1 following the dummy bar 5 and conveyed on the slab passage 2 in the direction indicated by the arrow. ing.

The dummy par storage device includes a trolley 7 installed in the horizontal part of the slab passage 2 of such a continuous casting machine so as to be movable on the side thereof or in a direction perpendicular to the slab conveyance direction; It consists of a U-shaped roller table 8 that is tilted sideways, and a dummy bar pulling arm 11 that is provided within the circular arc of the roller table 8 so that it can be rotated forward and backward by a drive device 10. The dummy bar 5 separated from the dummy bar 5 is stored on the roller table 8 by the arm 11.

This dummy bar storage device will be explained in more detail.

The trolley 7 has two opposing bifurcated legs 12 that are integrally connected at the opposing lower portions by a splicing member 13, and has wheels 15 on each lower portion of the legs 12 so as to be movable inwardly on the rails 14. A drive device 16 is provided.

A sideways U-shaped roller table 8 is installed between the legs 12 of this truck 7. This roller table 8 has an inclined straight part whose base end is pivoted and whose free end is supported by an elevating device fi9A so as to be freely raised and lowered, and a horizontal straight part formed above the inclined straight part. The roller table 8 has a lower end guide roller 17 for receiving a dummy bar, a lower guide roller 18, and an outer guide roller 19 on the inclined straight part and the arc part of the roller table 8. An outer guide plate 20 is provided continuously. and,
The slab separating device 9 is constituted by the inclined straight portion that is lifted and supported and the lifting device 9A. In addition, inner guide rollers 2 are provided at the arcuate portions and horizontal straight portions of the roller table 8.
1 and an upper guide roller 22 are continuously provided in two rows spaced apart so that the Anim 11 can be inserted therein.

A shaft 23 is rotatably mounted on the upper part of the leg 12 of the truck 7 by a bearing 24, and a drive device 10 (a motor 25 and a reducer 2) for rotating the shaft 23 in forward and reverse directions.
6) is installed. The shaft 23 is located at the center of the circular arc portion of the roller table 8, and two parallel dummy bar pulling arms 11 are fixed to the shaft 23. A locking pawl 27 is formed at the tip of the arm 11 and is inclined in the dummy bar pulling and storing direction (clockwise direction in FIG. 2). The length of this locking pawl 27 is determined by the length of the locking pawl 27 between the inner surface and the outer surface of the circular arc portion of the roller table 8, which is composed of the inner guide roller 21 and the outer guide roller 19, respectively.
The inner radius is larger than R1 so that the tip of 7 is located.
Moreover, it is formed smaller than the outer surface radius R2.

(Function) When storing the dummy bar 5, first move the trolley 7 to the traveling device 1.
5. ．． 16 and installed in the horizontal part (roller table 4) of the slab passage 2, the roller table 8 is connected to the roller table 4 by the lower end guide roller 17. Therefore, the dummy bar 5 is pushed by the slab 6 and is sequentially transferred from the roller table 4 to the roller table 8 from the dummy tail side. When the tip (tail) of the dummy bar 5 reaches the middle of the arc portion of the roller table 8, when the dummy bar pulling arm 11 is rotated in the dummy bar pulling and storing direction by the drive device 10, the locking claw 27 at the tip of the arm 11 locks the dummy bar. In order to enter the parallel link 5 of 5 and lock it with the connecting pin 5B, the dummy bar 5
is pulled around while being guided by the outer guide roller 19 of the roller table 8, the outer guide plate 20, and the inner guide roller 21 by the arm 11 that is engaged with the dummy bar 5, and the tail portion of the dummy bar 5 is placed on the upper guide roller 22. When the slab is placed, the slab separation device 9 is operated to separate the slab from the dummy par head, and storage is completed. After storing the dummy bar, the slab 6 from which the dummy bar 5 has been separated is conveyed on the roller table 4 located in the carriage 7.

When inserting the dummy bar 5 from below the mold 1, first the cart 7 is installed in the slab passage 2, and the roller table 8 is connected to the roller table 4.

Next, the dummy bar pulling arm 11 is connected to the drive device 1.
When the dummy bar 5, which is engaged with the arm 11, is rotated in the opposite direction by 0, the dummy bar 5, which is engaged with the arm 11, moves on the roller table 8. Since the dummy bar 5 can be actively pushed by pressing the arm 11 against the other connecting pin 5B facing the space 5C into which it is inserted, the dummy bar 50) head side moves from above the roller table 8 to the roller table 4. The dummy bar 5 is reliably moved upward and further between the support rolls 3, and is pulled out from above the roller table 8 by the gripping drive of the support rolls 3. After pulling out the dummy bar, the cart 7 remains in that position and waits for the next dummy bar storage.

(Effects of the Invention) As described above, the present invention has a structure in which the dummy bar can be stored and held on a sideways U-shaped roller table by means of a dummy bar pulling arm provided in an arcuate portion of the roller table. It can be made compact, and combined with the simple structure, the equipment cost can be reduced. The length of the horizontal straight section of the roller table can easily accommodate the length of the dummy bar. Furthermore, since maintenance of the dummy bar can be performed on the horizontal straight section of the roller table, maintainability can be improved.
