The utility model belongs to the field of metal smelting, in particular to a lifting and lateral moving device for a smoke hood of a converter.

Most of the converter hood lifting and moving devices used at home and abroad at present adopt the method of separating the movable hood lifting and the translational hood swaying. Structurally, the translation hood is installed on the traversing trolley, and the lifting mechanism of the movable hood is installed on the fixed platform under the traversing trolley, and the traversing trolley can only move the translation hood laterally. This structure is not conducive to the maintenance of the converter because the movable hood and the translational hood cannot be moved horizontally as a whole; the lifting mechanism of the movable hood is limited by the installation position, and the piston rod of the oil cylinder is directly connected with the movable hood, and the cylinder and the piston rod of the oil cylinder are close to the flame. As the heat source, although the oil cylinder adopts a special water-cooled oil cylinder, due to the inability to solve the heat conduction of the piston rod of the oil cylinder, the phenomenon of oil leakage due to damage to the seal of the oil cylinder often occurs during use, which greatly increases the workload of maintenance.

Each connection is covered with a heat insulating ring on the connecting pin, which constitutes the thermal resistance to the heat conduction of the tie rod: The tie rod passes through the sealing plate, the floating air seal ring and the sealing box, successively passes through the pull rod adjustment device with sheath, the connecting plate joint, and uses the connecting pin to connect with the connecting plate and the smoke hood joint, and then connects with the lifting smoke hood. The floating air seal ring allows the pull rod to have a certain deflection, and the pull rod adjustment device with sheath can adjust the installation height and level of the smoke hood.

The sealing box is installed at the lower end of the water-cooling protective support sleeve. There is a floating air-sealing ring inside the sealing box. The seal in the water-cooled protective support sleeve; the tie rod is connected with the connection plate joint through the adjustment bolt, the connection plate joint is connected with the connection plate through the connection pin, the connection plate and the connection plate are also connected through the connection pin, and the connection plate is connected with the hood joint through the connection pin Connected, the smoke hood joint is connected with the lifting smoke hood.

In the above scheme, the hood lifting mechanism provides the lifting function of the movable hood, and a traverse trolley composed of frame, transmission device, driving wheel and driven wheel is the hood lifting mechanism, heat protection water cooling plate and translational hood. components provide support. The oil cylinder is installed upright in the water-cooled protective support sleeve and the thermal resistance structure for the heat conduction of the tie rod and the sealing measures for the water-cooled protective support sleeve, so as to effectively cut off the heat source and heat conduction. , The heat protection water cooling plate can be moved out as a whole. Improve the reliability and working life of the oil cylinder, reduce equipment maintenance costs and repair time.
