Abstract

The invention discloses a safe and reliable two-section type covering and uncovering device for a ladle. The safe and reliable two-section type covering and uncovering device for the ladle comprises a ladle cover, electric-hydraulic pushers and a base. The ladle cover is connected with telescopic rockers and guide rockers in a rotating mode. Each telescopic rocker comprises rocker arms and gear transmission cases. Each gear transmission case comprises a case body which is connected with the base in a rotating mode. A gear transmission set comprising a power input rotating shaft and power output gears is arranged in each case body, and one gear of each gear transmission set is an incomplete gear. Each case body is fixedly connected with the power input rotating shaft of the corresponding gear transmission set. Each case body is further provided with a sliding groove. The rocker arms are in sliding connection with the case bodies through the sliding grooves, and the case bodies are driven by the rocker arms to rotate together with the rocker arms. One end of each rocker arm is connected with the ladle cover in a rotating mode. Teeth are arranged at the other end of each rocker arm so that a rack can be formed, and each rack is engaged with the power output gears of the corresponding gear transmission set. The rocker arms in each telescopic rocker are connected with the corresponding electric-hydraulic pusher.

Description

technical field [0001] The invention belongs to the technical field of heat preservation equipment for molten iron transportation in engineering equipment, and in particular relates to a safe and reliable two-lobed ladle uncovering device during the transportation of molten iron. Background technique [0002] At present, open ladles are still used to transport molten iron from the blast furnace to the converter. It is well known that smelting iron ore into molten iron requires a lot of energy. However, the distance between the blast furnace and the converter in the steelmaking plant is often far away, and they are not in the same workshop. Transporting molten iron from the blast furnace to the converter with an open ladle will inevitably lead to continuous heat exchange between the molten iron and the air, resulting in molten iron The furnace temperature is lowered, which ultimately increases the cost of steelmaking. And in rainy and snowy weather, safety accidents are ver...
