Abstract

PURPOSE:To enable the attaching/detaching work of a mold regardless of the working condition of an overhead crane by providing a ladle lifting device for lifting the ladle and a mold lifting device for lifting the mold on a small carriage on a ladle carriage. CONSTITUTION:The ladle small carriage 1 is arranged on a girder 2 in the ladle supporting carriage 20 and travelles on the girder 2. A hanging ring 3 for hanging down the ladle, provided on the small carriage 1 is freely attached on/detached from the ladle 11, and the ladle 11 can be lifted by a cylinder 6 for lifting the ladle. Further, the ladle 11 can be tilted by a cylinder for tilting hanging ring. A hanging hook 4 for the mold and mold-only body provided on the small carriage 1 is freely attached to/detached from the mold 14, and since the mold can be lifted by winding up the hanging hook with a winch 9 through a wire 7 and a sheave 8, the attaching/detaching work of the mold 14 can be executed in the ladle supporting carriage 20 regardless of the working condition of the overhead crane, and the time for preparing casting can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladle support carriage for continuous casting equipment.

[0002]

2. Description of the Related Art As a conventional technique, for example, Japanese Unexamined Patent Publication No. 53
There are ladle support carriages disclosed in JP-A-6233 and JP-A-54-137434. The feature of these techniques is to support and move the ladle on the ladle supporting carriage on the carriage, and does not replace the mold and the mold-dedicated body. Normally, the mold and the mold-dedicated body are exchanged by an overhead crane arranged on the continuous casting facility building.

[0003]

Since the mold and the mold-dedicated body come into contact with molten steel and cast slabs at a particularly high temperature during operation, the mold copper plate is worn or flawed, and the dedicated body cannot be replaced due to wear or crack of the roll. You will need it. Further, in recent years, in continuous casting equipment, it is necessary to frequently change the mold and the mold-dedicated body in accordance with the cross-sectional shape of the cast piece to be cast with the increase in the production of various kinds of small lots.

Normally, the mold and the dedicated mold are replaced after the casting is completed, but after the casting is completed, the ceiling crane is restrained for carrying the pan and discharging the slag accumulated in the pan. A considerable waiting time occurs before starting the replacement work, which leads to an increase in casting preparation time, which is a major obstacle to securing the production amount.

[0005]

DISCLOSURE OF THE INVENTION The present invention is a ladle support truck, characterized in that the ladle support truck is provided with a device for exchanging a mold and a mold-dedicated body. Then, on a small carriage that can run on the ladle support carriage, a detachable pot hanging device, a pot lifting device for raising and lowering the pot with the hanging device, a detachable mold hanging device, and a mold using the hanging device. And a mold lifting device for lifting the dedicated mold body.

[0006]

According to the present invention, the small truck is provided on the ladle support carriage, and the small truck is provided with the raising / lowering function of the pot, the mold, and the mold-dedicated body. It is possible to remove the body from the continuous casting machine and freely convey the mold and the dedicated mold body on the operating floor.Also, regardless of the work state of the overhead crane, the replacement work of the mold and the dedicated mold body can be performed without delay. It became possible.

[0007] Then, on a small carriage that can run on the ladle support carriage, a detachable pot hanging device, a pot lifting device for raising and lowering the pot by the hanging device, a detachable mold hanging device, and its hanging. Since the mold raising / lowering device for raising and lowering the mold and the dedicated mold body is provided by the tool, it is possible to provide a compact ladle support cart having both the ladle exchange function and the exchange function of the mold and the dedicated mold body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete description will be given below based on the embodiments shown in the drawings. 1 and 2 are schematic explanatory views of a ladle support truck of the present invention, FIG. 1 is a side view, and FIG. 2 is a plan view. The ladle small cart 1 is a ladle supporting cart 20.
It is placed on the garter 2 and runs on the garter 2.
The ladle small trolley 1 is equipped with a hanging ring 3 for hanging a pot and a hanging hook 4 for a mold and a mold-dedicated body. The cylinder 6 enables the lifting and lowering. The suspension hook 4 which is a dedicated body for the mold and mold is wound by a winding device 9 arranged above the ladle small truck 1 via a wire 7 and a sheave 8 and can be raised and lowered.

FIG. 3 is a cross-sectional view of the ladle support cart of the present invention, showing the ladle 11 loaded. The hanging ring 3 for hanging the pan can be tilted by the cylinder 10 for tilting the hanging ring, and the pan 11 can be attached to and detached from the trunnion shaft 12. Hanging hooks for molds and dedicated molds 4
Is wound up in a standby state and guided by a guide rail 13 provided in the ladle small truck 1 to be stored.

FIG. 4 is a sectional view of the same ladle support carriage, showing a state where the mold and the mold-dedicated body 14 are lifted. Mold for continuous casting machine and dedicated mold 14
In the desorption work of, the centering work is important.
Therefore, a centering cylinder 16 is provided on the saddle portion 1 of the ladle small truck 1 so as to enable reliable centering. Then, the mold and the mold-dedicated body 14 are lifted up by the suspension hooks 4 of the mold and mold-dedicated body, and the suspension hooks 4 are guided by the garter 2 of the ladle support cart to prevent steadying when the ladle support cart travels.

FIG. 5 is a side view of the ladle support carriage, showing a state in which the mold and the mold-dedicated body 14 are lifted. An electric cylinder 17 for hook tilting is built in the suspension hook 4 of the dedicated mold and mold body, and by lifting the trunnion pin 18 arranged inside the dedicated body of the mold and mold 14, the lifting can be performed.

The mold and the mold-dedicated body 14 which have been prepared in advance are mounted on a working floor by an overhead crane (not shown) on a working floor of the crane, and after being detached from the continuous casting machine, they are used. The mold and the mold-dedicated body are temporarily placed on the operating floor, and they are transported by the crane while the overhead crane is idle.

The embodiment in which the ladle 11 and the mold / mold-dedicated body 14 can be carried by the single ladle small truck 1 has been described above. It is okay to carry out the handling of 14 by a separate small truck, and
Depending on the layout of the operating floor, the mold and the mold-dedicated body 14
The handling function may be fixedly arranged at any position on the garter 2 of the ladle support cart.

[0014]

EFFECTS OF THE INVENTION According to the present invention, it is possible to attach and detach the mold and the mold-dedicated body with the ladle support carriage regardless of the working condition of the overhead crane, and only the mold and the mold are provided under the restriction of one ceiling crane. It has become possible to shorten the casting preparation time for body replacement to about 80 minutes, compared to about 120 minutes in the conventional case. In addition, instead of adding an overhead crane, a ladle small truck is sufficient, and it is possible to reduce equipment costs.
