Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention defines a part of a traveling rail in a slag yard of a mixed smelting car for tilting the mixed smelting car to discharge the contents, or in a molten metal slag receiving and payment site. The present invention relates to an improvement of a traveling rail moving facility for a mixed piggy car that retreats from a position and prevents adhesion of molten pig iron.

<Prior Art> When pretreatment such as desiliconization, dephosphorization, and desulfurization of hot metal is performed using a hot metal wheel, the molten slag after the processing accumulates and remains in the furnace (in the hot metal wheel). When the remaining molten slag is cooled, it adheres to the inside of the furnace and reduces the internal volume of the furnace, which causes a decrease in the capacity of the hot metal.

A decrease in the hot metal capacity has a serious effect on the operation, such as a decrease in the transport efficiency, a decrease in the hot metal temperature, and a decrease in the reaction efficiency of the refining agent. Therefore, it is necessary to discharge the molten metal in the mixed pig iron wheel at regular intervals.

Therefore, after allocating the molten pig iron to the slag yard, first of all, by tilting, the molten pig iron, which is the content remaining in the furnace, is discharged, and further tilted to discharge the molten pig iron. It is unavoidable that hot metal and slag adhere to the rails on which the car runs.

<Problems to be solved by the invention> Since it is troublesome for the worker to scrape off the pig iron and slag attached to the traveling rail with a stick, the processing cycle time increases, so the traveling rail should be improved in order to improve this. A means for arranging a protective cover on the upper surface has been proposed (Shokai Sho 62-1).
See No. 14045). This is to cover the traveling rail with a protective cover when it is discharged from the towed car, and to withdraw the protective cover from the traveling rail when the towed car travels.

However, in the case of this means, foreign matter is caught between the protective cover and the traveling rail, and the defective operation is frequently caused by the drop and slag on the protective cover, which increases the maintenance cost and hinders the reduction of the processing cycle time. There was a problem.

On the other hand, in Jaikai Sho 62-114044, a partial traveling rail that separates the traveling rails of the torch car is installed on the traverse vehicle, moved to the evacuation position together with the traverse vehicle, and then discharged from the tow truck. A means for preventing the pig iron and slag from adhering to the rail is disclosed.

By this means, adhesion to the traveling rail is completely prevented, but it is difficult to position the partial traveling rail when returning it to the fixed position, and it is difficult for the joints of the traveling rails to match easily and there is a tendency for misalignment to occur. There is a problem in that a heavy towed car is unstable because it is supported by the wheels of a traverse carriage.

The present invention solves the conventional problems described above, and the partial traveling rail, which is a part of the traveling rail of a mixed-metal car, is separated and separated, and the partial traveling rail is evacuated to the outside of the range where the iron and slag fall to completely prevent them from adhering and discharging. It is an object of the present invention to provide a traveling rail moving facility for a towed vehicle that can reliably set the partial traveling rail from a retracted position to a fixed position on a traveling track when the work is completed.

<Means for Solving the Problems> The present invention for achieving the above object will be described with reference to the drawings. In the present invention, the traveling rail 3 of the mixed piggy car 1 is defined as a distance from the inner distance l between the bogie carriages 2 of the mixed piggy car 1. The partial traveling rails 4 separated and divided over a short section are mounted on a traverse carriage 6 moving on a traverse rail 5 provided in a direction traversing the traveling rail 3, and the traverse carriage 6 is provided with the traverse carriage 6. 6 is provided with a wheel raising / lowering means 15 for raising / lowering the traveling wheels 14 of the vehicle 6 and a projection member 16 for positioning and supporting the traverse carriage 6
At the fixed position of the transverse carriage 6, the wheel elevating means 15 is operated to raise the traveling wheels 14, and the protruding member 16 is provided on the transverse carriage seat 7 arranged in the vicinity of the transverse rail 5. The traverse carriage 6 is supported with the partial traveling rails 4 aligned with the traveling rails 3 of the mixed piggy car 1, together with the transverse traveling carriage 6 of the partial travel rails 4 prior to the work of discharging the contents from the mixed piggy car 1. When moving to the retreat position, the wheel elevating means 15 is operated to lower the traveling wheels 14, and the projecting member 16 is disengaged from the transverse carriage seat 7 so that the traveling wheels 14 are positioned on the transverse rail 5. It is configured in.

<Operation> In the present invention, when the molten pig iron is discharged from the mixed piggy car 1 by the above-mentioned means, the traveling wheels 14 of the traverse carriage 6 having the partial traveling rails 4 are driven by a drive device (not shown) to move to the retracted position. Prevents pig iron and slag from adhering to the rails.

When the discharge of the molten pig iron is completed, the wheel elevating means 15 provided on the traverse carriage 6 as a power source such as hydraulic pressure and electricity is driven to drive the traveling wheels.
By raising 14 to lower the traverse carriage 6 and setting the projecting member 16 while guiding it to the traverse carriage seat 7, the partial traveling rail 4 is surely aligned with the traveling rail 3 without being displaced and is stable. Support in the state of being.

<Example> Hereinafter, an example of the present invention will be described.

In FIG. 1, reference numeral 1 denotes a tow truck, which is distributed to a cleaning center on the traveling rail 3 to remove the debris adhering to the furnace opening portion of the tow truck 1 by a drifter 18 attached to a boom 17 of the detoner 9. It shows the state. Reference numeral 10 is a dust collecting hood, and the generated dust is passed through the damper 12 to the main duct.
