Electrical-control vehicle-mounted capping mechanism device for hot metal ladle

Abstract

The invention relates to an electrical-control vehicle-mounted capping mechanism device for a hot metal ladle. The electrical-control vehicle-mounted capping mechanism device adopts a motor as a power source and a trolley / cam linkage mechanism as an actuating mechanism to realize horizontal movement and achieve the function of capping / uncapping as required, thereby reducing heat loss of liquid steel and obtaining more economic benefits. The invention realizes safety, reliability and adaptability of the capping mechanism of the hot metal ladle in operation by virtue of the felicitous coordination of all rod group mechanisms. The electrical-control vehicle-mounted capping device comprises three main parts, namely a rail guided trolley mechanism, an electric rod group mechanism and a ladle cap mechanism. The working principle of the electrical-control vehicle-mounted capping mechanism device is that the motor drives the trolley to move to realize the horizontal movement of a ladle cap, and through the combination of an electric push rod-drive cam mechanism and the linkage mechanism, a capping / uncapping action is realized so as to enable the hot metal ladle to be closely covered with the ladle cap. A slotted hole is formed in the ladle cap; and in coordination with the linkage mechanism, the ladle cap still can be closely fitted with the hot metal ladle on the condition that the hot metal ladle expands and sand sticks to the edge of the iron ladle.

Description

technical field [0001] The invention relates to a mechanism device for electronically controlling vehicle-mounted iron ladle capping. Its principle is to use a motor as a power source, and use a trolley / rod group structure as an actuator to achieve the required horizontal movement with the minimum power, materials and cost. And the lid closing / opening function, so that without changing the existing factory building and equipment, the iron ladle can be covered on the molten steel hauling train, adapting to the new process of one ladle to the end, reducing the heat loss of molten steel, and achieving a higher economic benefits. Background technique [0002] The electronically controlled vehicle-mounted iron ladle capping mechanism is mainly composed of three parts: a trolley mechanism, an electric rod group mechanism and a capping mechanism. Its working principle is to realize the horizontal movement of the cover through the movement of the trolley, and realize the closing / op...

AI Technical Summary

Problems solved by technology

[0003] The existing iron clad capping mechanism has the following shortcomings: 1. The overall mass of the iron clad closing / opening action is too large, exceeding the carrying capacity of the hauling train, affecting driving safety and service life; 2. Lack of self-positioning Function, when there is sticky sand at the ladle mouth, the tight fit between the ladle cover and the iron ladle cannot be realized, resulting in heat loss and reducing economic benefits; 3. Adopting hydraulic drive, it has a greater impact in the high-temperature working environment of loading, unloading and transporting molten iron. safety hazard, low reliability
