Description

[Detailed Description of the Invention] This invention relates to a transport vehicle for transporting high-temperature molten materials, such as steel slag or molten steel, using a melting device such as a ladle.

Molten products during metal refining, such as hot metal, molten steel, blast furnace slag, steelmaking furnace slag, etc., are generally transported to a suitable next processing site in a ladle or a railway vehicle such as a torpedo car.

In addition, when the high-temperature molten material is relatively small, for example, the amount of slag removed from the molten steel ladle or tundish during ingot making and casting is relatively small, so it is stored in a small ladle such as a pan and used in a loading type steel slag dump truck. and other road vehicles to the appropriate next-process treatment plant.

Among these vehicles for transporting high-temperature molten material, it has been proposed that the above-mentioned railroad transport vehicle have a lid on the opening of the molten material inlet, etc. The device has been announced.

However, transport vehicles such as steel slag dump trucks and other road vehicles have not yet been provided with an appropriate opening/closing lid device.

However, in vehicles transporting high-temperature melts by road, no matter how well-developed the transportation roads are, it is impossible to avoid the vibrations caused by the vehicles, and the overflow of the stored materials due to vibrations cannot be avoided. In order to prevent this, it was necessary to drive slowly or to smoothen the road surface, which inevitably led to inefficient operation and an increase in equipment costs, which caused many problems in terms of equipment and safety. .

In addition, when these high-temperature materials are transported with the top of the pot open, the amount of heat released from the surface of the melt is extremely large, and the temperature of the stored melt, especially at its surface, drops significantly, resulting in a decrease in fluidity, etc. This caused a great deal of inconvenience in subsequent processing.

This invention was made to solve the various problems mentioned above, and will be described in detail below with reference to the drawings.

The traveling chassis 1 is installed on a self-propelled vehicle such as a truck, which is manufactured as appropriate depending on the size of the carrying load, and is not particularly limited in the present invention, but is used to store high-temperature molten material. It should have the necessary strength and fire resistance to mount the ladle.

A shaft 4 to which an end of a support leg 3 of a ladle mounting base 2 is attached is rotatably provided at the rear end of the traveling platform 1.

An engagement recess 6' of an engagement protrusion 6 provided on the side wall of the ladle 5 is provided at the upper portion of the other end of the support leg 3.

The curved shape of the inner surface of this engaging recess 6' may be a simple shape that simply accommodates and engages the protrusion 6 when the ladle 5 is simply transported and will not be overturned. When tipping over and discharging stored items, the concave curved surface is formed to match the locus of movement of the protrusion 6, which is determined by the installation position of the protrusion 6.

Further, an insertion hole 7 for a locking pin 7' is provided in the intermediate portion of the support leg 3 to prevent the ladle from swinging during transportation.

The means for preventing rocking of the ladle may be replaced by means for directly engaging the bottom of the ladle and the traveling chassis.

A piston rod of a cylinder 10 is pinned to an arm 9 fixed to a shaft 8, which is rotatably provided on the opposite side of the support leg mounting shaft 4 and has one end extending over the traveling chassis 1 at the lower middle part of the support leg 3. is connected to via an arm 11.

Reference numeral 12 designates a link having one end pinned to an arm 13 attached to the aforementioned shaft 8 at a constant phase angle with respect to the arm 9, and the other end pinned to the vicinity of the mounting shaft 4 of the supporting leg 3 via an arm 14. .

A support frame 16 is provided at one end of the traveling chassis 1, on the driver's cab 15 side, and an elevating frame 17 is rotatably provided at a midpoint thereof at a position corresponding to the height of the loaded ladle.

The rear end 18 of the elevating frame 17 is connected to a reciprocating rod 19' of a suitable drive device 19 such as a cylinder device installed at a suitable position such as the support frame 16.

A refractory lining is applied to the lower surface of the elevating frame 17 at a position opposite to the ladle 5 to form a cover portion 20.

By spreading and installing a fire-resistant elastic material such as asbestos on the contact area of the fireproof lined bunker lid part 20 with the upper edge of the ladle 5, damage caused by impact when opening and closing the bunker lid or suppressed vibration after closing the lid can be avoided. However, if the lid opening/closing operations can be performed without impact, the use of the above-mentioned elastic refractories is not necessary.

The device of the present invention is constructed as described above, but the ladle 5 containing a high-temperature molten material such as molten steel slag is placed in the engaging recess 6' of the ladle mounting table 2 using appropriate cargo handling equipment. Coupling protrusion 6
Then, the cylinder device 19 is actuated to move the rear end 18 of the elevating frame 17 upward, and the elevating frame 17 is rotated downward. The lid portion 20 lined with a refractory material is pressed against the upper edge of the ladle 5 to cover the ladle.

After being transported to the destination in such a state, the lid is opened by operating the cylinder 19 in the reverse direction.

Next, by operating the cylinder 10, the ladle mounting base 2 is overturned as shown by the chain line, thereby allowing the high-temperature contents to be discharged.

Since the device of the present invention is constructed as described above, it is possible to transport high-temperature molten material by road vehicle safely and without a drop in temperature with an extremely simple construction.
