BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tundish transfer truck used in a continuous casting facility.

[0002]

2. Description of the Related Art As is well known, in a continuous casting facility, a tundish placed on a tundish car is arranged between a ladle and a mold, and molten steel from the ladle is poured into a mold. . This tundish is often replaced together with the mold (for example, Japanese Patent Publication No. Sho 5
2-333049, Japanese Utility Model Publication No. 1-37815, etc.).

[0003] Recently, the tundish is exchanged by using a tundish transfer cart in addition to the tundish car.
This is done in a tundish exchange zone in the casting bed. The mutual relationship between the tundish, the tundish car and the tundish transfer cart in the exchange zone is as shown in FIGS.

[0004] That is, for example, the discharged tundish 1 is placed on a tundish transfer truck 2, and the transfer truck 2 is placed on an empty tundish car 3, and the tundish 1 is transferred to the tundish car 3. Transferred or used tundish 1 from tundish car 3
To the transfer trolley 2. That is, the tundish 1 of the tundish car 3 is moved to the transfer cart 2.

The transfer truck 2 travels on transfer truck rails 5 and 5 laid on a casting floor 7, and the tundish car 3
Travels on car rails 6,6. The car rails 6 are laid on both sides of the casting floor 7 with a mold (not shown) interposed therebetween. The transfer cart rails 5 are arranged on both sides of the car rail 6 extended to the exchange zone. Has been laid.

The tundish 1 is supported by a lifting frame 8 of the transfer carriage 2. This lifting frame 8
.. Are formed by horizontal members that are supported at both ends by hydraulic cylinders 9 as supporting columns. These hydraulic cylinders 9 stand on the transfer cart 2. Therefore, the tundish 1 is supported by the portal type four-point support structure.

[0007] An inverted Y2 hole type sliding nozzle 10 is suspended from one side of the bottom of the tundish 1, and a nozzle operating cylinder 10a protrudes outward of the long side of the tundish 1 from the sliding nozzle 10. ing.

Therefore, in order to transfer the used tundish 1 to the transfer cart 2, the transfer cart 2 is approached from the side of the tundish 1 mounted on the tundish car 3, and Then, the lifting frame 8 is raised to receive the tundish 1.

[0009]

Recently, the tundish 1 and the transfer cart 2 have been reduced in size and size to reduce the space for the casting floor 7. However, in the above-described tundish 1 and the transfer cart 2, if both of them are to reduce the length of the tundish 1 in the long side direction, the transfer cart 2 raises the lifting frame 8 to receive the tundish 1. There is a problem that the hydraulic cylinder 9 supporting the lifting frame 8 interferes with the nozzle operating cylinder 10a protruding in the long side direction of the tundish 1.

Therefore, it is conceivable to provide the nozzle operating cylinder 10a of the sliding nozzle 10 orthogonally to the illustration or to project it in the opposite direction, ie, inward, as shown in the figure. The nozzle operating cylinder 10a
Is restricted by this nozzle, the former idea cannot be adopted, and the latter idea cannot be adopted for maintenance and inspection.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve such a problem, and the gist of the invention is that a tundish car (3) is provided between a mold and a ladle of a continuous casting facility. The tundish (1) placed on the tundish (1) is placed, and in order to replace the tundish (1), the tundish car (3) is moved to a tundish exchange zone to be placed sideways on the tundish transfer cart (2). The tundish (1) of the tundish car (3) is lifted by the hydraulic cylinder (9) of the tundish transfer carriage (2), and is transferred to the carriage (2).
In a continuous casting facility for exchanging a tundish (1), a mast stand (11) is provided on one side in the traveling direction of the tundish transfer cart (2), and is guided by the mast stand (11) and travels. The base of the fork (8a) projecting in the direction is provided so as to be able to move up and down, and
A hydraulic cylinder (9) that supports the fork (8a) so as to be able to move up and down is erected, and the hydraulic cylinder (9) is protruded outward from the long side of the tundish (1). 10a) A tundish transfer cart for continuous casting equipment, which does not interfere with 10a).

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a plan view of FIG. 1. In FIG. It is attached.

On one side of the traveling direction of the tundish transfer vehicle 2, a mast stand 11 is provided upright perpendicular to the traveling direction. A pair of H-shaped guide rails 12 are provided on the inner surface side of the carriage of the mast stand 11. The guide roller 13 rolls on the H-shaped guide rail 12. The guide rollers 13 are provided at two locations above and below the base of the fork 8a projecting in the running direction.

Therefore, the fork portion 8a is attached to the mast stand 11 via the H-shaped guide rail 12 and the guide roller 13 so as to be able to move up and down. In the fork portion 8a, a substantially middle portion of the fork is supported by hydraulic cylinders 9, and these hydraulic cylinders 9 stand on the transfer carriage 2.

In the drawing, reference numeral 14 denotes a traveling wheel having the same structure as that of the conventional example, and rolls on the rail 5 for the transfer truck.
The traveling wheels 14 are driven by a traveling motor 15 mounted on the stand 11. In addition, 16 shows a part of building.

Therefore, in order to reduce the area occupied by the casting floor 7, the tundish 1 and the transfer cart 2 are made compact and compact, and the nozzle operating cylinder 10a projects outward in the long side direction of the tundish 1. Also, since the tundish 1 is lifted by inserting the fork portion 8a of this embodiment along the short side of the tundish 1, it does not interfere with the nozzle operating cylinder 10a.

The piston rod end (the tip of the rod) of the hydraulic cylinder 9 of this embodiment is connected to the fork portion 8.
The fork a supports a substantially middle portion of the tundish mounting portion, but the present invention is not limited to this, and the hydraulic cylinder 9 may be built in the mast stand 11.

[0018]

According to the present invention, a fork is provided on a tundish mounting cart in the traveling direction of the bogie, that is, a fork is provided along the short side of the tundish, and the tundish is lifted or lowered using the fork. So
The tundish placed on the tundish car or the nozzle operating cylinder of the sliding nozzle of the tundish to be placed on the tundish car does not interfere with the hydraulic cylinder that moves the fork up and down. Further, since the fork is a fork, the number of hydraulic cylinders for raising and lowering the fork can be reduced. As a result, the area occupied by the tundish exchange zone can be reduced.
