Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a dumping vehicle with a heat shielding device. Background Art

[0002] During the steelmaking process, steel mills usually need to use ladles to transfer molten steel from blast furnaces to quantum electric furnaces. The ladle usually needs to be hoisted onto a molten steel dumping truck by a crane, and then the ladle is lifted up and tilted by a lifting device installed at the rear of the molten steel dumping truck, so that the molten steel in the ladle is introduced into the quantum electric furnace through the guide groove on the dumping truck. In order to increase the potential energy of the molten steel, the dumping truck is usually placed on the second-floor platform above the quantum electric furnace, and then the dumping truck transports the ladle to the quantum electric furnace by rail, and then dumps the ladle. Since a variety of related pipelines and wires are installed above the quantum electric furnace, when the molten steel is dumped, due to the high temperature of the molten steel, it is easy to cause damage to the equipment and wires located above, causing failures, seriously affecting production efficiency, or causing safety hazards.

[0003] Therefore, a dumping car with a heat shield is needed to reduce the impact of molten steel on the upper equipment of the quantum electric furnace. Utility Model Content

[0004] The main purpose of the utility model is to provide a dumping car with a heat shielding device. When the ladle injects molten steel into the quantum electric furnace through the dumping car, the heat shielding device is installed to reduce the harm of the molten steel to the upper equipment of the quantum electric furnace.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dumping vehicle with a heat shield device comprises a vehicle body, wherein the vehicle body is provided with a guide groove, and the vehicle body is detachably provided with a heat shield plate, wherein the heat shield plate is arranged in front of the guide groove.

[0007] Furthermore, a bracket is provided on the vehicle body, and the bracket is arranged on both sides of the guide groove. A column is provided at the lower end of the heat shield, and the column is inserted and fixed in the bracket.

[0008] Furthermore, the upper end of the column is fixedly connected to a limit plate, and the column gradually widens from the bottom to the limit plate.

[0009] Furthermore, a hanging ring is provided on the top of the heat shield.

[0010] Furthermore, the heat shield comprises a bottom plate, a side of the bottom plate facing the guide groove is cast with refractory casting material, and the other side of the bottom plate is welded and fixed with reinforcing ribs.

[0011] Furthermore, anchor nails are welded on the surface of the bottom plate cast with the refractory castable material.

[0012] Furthermore, the thickness of the refractory castable is 16-30 cm.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting up a detachable heat shield, the influence of heat radiation on the upper equipment of the quantum electric furnace when the molten steel is poured can be effectively reduced, and at the same time, the maintenance of the car body will not be affected.

[0015] 2. The heat shield is provided with a column which matches the bracket on the vehicle body, so that it is convenient for lifting, disassembling and assembling.

[0016] 3. The heat shield can be effectively limited by setting the limit plate to avoid the problem of too tight connection and difficult lifting. The column can be inserted into the bracket by gradually widening the width from the bottom to the limit plate.

[0017] 4. The heat shield can be easily hoisted by setting a lifting ring on the top.

[0018] 5. By setting refractory casting material on one side of the heat shield and setting reinforcing ribs on the other side, the overall strength and heat shielding effect of the heat shield are improved.

[0019] 6. The heat shield is easier to pour refractory materials by setting anchor nails. BRIEF DESCRIPTION OF THE DRAWINGS
