Six-connecting-rod control device for heat-insulating cover of hot-metal bottle

Abstract

The invention provides a six-connecting-rod control device for a heat-insulating cover of a hot-metal bottle. Two six-connecting-rod mechanisms are separately connected to two sides of a heat-insulating cover, and is supported by an upper fixing hinged point and a lower fixed hinged point which are positioned beside the hot-metal bottle on a hot-metal car. The six-connecting-rod mechanism comprises a cover connecting rod, an upper driving rod, a lower driving rod, an upper driven rod and a lower driven rod, and the cover connecting rod is fixedly connected with the heat-insulating cover; one end of the lower driving rod is hinged to a lower fixing hinged point, and the other end of the lower driving rod is hinged to one end of the cover connecting rod; one end of the upper driving rod is hinged to the upper fixing hinged point while the other end is hinged to the upper driven rod and the lower driven rod; one end of the upper driven rod is hinged to the middle of the cover connecting rod while the other end is hinged to the upper driving rod and the lower driven rod; and one end of the lower driven rod is hinged to the upper driving rod and the upper driven rod while the other endis hinged to the lower driving rod. The six-connecting-rod control device for the heat-insulating cover of the hot-metal bottle is used for controlling the heat-insulating cover of the hot-metal bottle, and opening and closing of the heat-insulating cover can be operated conveniently, rapidly and safely.

Description

technical field [0001] The invention belongs to the technical field of production equipment in iron and steel, metallurgy and foundry industries, and in particular relates to an operating device for a heat preservation cover of a molten iron tank. Background technique [0002] In iron and steel plants, metallurgy, and foundry industries, molten iron tanks are generally used to transfer and transport molten iron. In the process of transferring and transporting molten iron, most of them adopt open transportation. This kind of open transportation not only consumes a lot of energy, but also pollutes the environment with high-temperature flue gas. Transporting high-temperature liquid metal containers with thermal insulation covers can reduce the heat loss during transportation, which is an important way to save energy, reduce consumption and protect the environment. Some of the current operating mechanisms for special insulation covers use hoisting methods, and some use special...

AI Technical Summary

Problems solved by technology

Some of the current operating mechanisms for special insulation covers use hoisting methods, and some use special mechanisms. Most of them have the disadvantages of large footprint, complex equipment structure, large movement space, and unsafe actions

Coupled with the special environment of metallurgy, casting and other areas, the temperature is high, dust and iron slag are much, and the operation of the equipment is unreliable
