Bridge-type mechanical arm for steel ladle lining refractory disassembly and operating method thereof

Abstract

The invention provides a bridge-type mechanical arm for steel ladle lining refractory disassembly and an operating method thereof. A mechanical arm working body is hoisted onto an operating platform when operation is required and is fixed to the ladle opening center point of a vertical steel ladle, and multi-directional refractory disassembly of a steel ladle lining is achieved through working arm rotation and hydraulic hammer swinging. The bridge-type mechanical arm is simple in structure, convenient to maintain, and capable of achieving wired control operation, resisting high temperatures, greatly reducing occupational health hazards of employees and relieving the labor intensity of the employees. Moreover, the limitation that the temperature of the inside of the steel ladle is high and thus people cannot enter the steel ladle for manual disassembly is avoided, operating efficiency is improved, the tense turnover pressure of the steel ladle at the site can be lowered, and production requirements are guaranteed.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a bridge-type manipulator for dismantling refractory materials lining ladles; [0002] The invention also relates to the operation method of the bridge-type manipulator used for dismantling the steel ladle lining refractory material. Background technique [0003] At present, in the iron and steel smelting industry, the removal of refractory materials for the lining of Shenggang containers is based on the different structures of the applicable objects and different process requirements. There are simple tools for manual operation, crawler-type unpacking machines for engineering machinery vehicles, and bridge-type furnace unpacking machines. At present, the removal of the inner lining and refractory material of the ladle in the domestic steelmaking plant is to dismantle the ladle horizontally on the unpacking table, and the crawler unpacking machine is generally used for dismantling.

[0003] At present, in the iron and steel smelting industry, the removal of refractory materials for the lining of Shenggang containers is based on the different structures of the applicable objects and different process requirements. There are simple tools for manual operation, crawler-type unpacking machines for engineering machinery vehicles, and bridge-type furnace unpacking machines. At present, the removal of the inner lining and refractory material of the ladle in the domestic steelmaking plant is to dismantle the ladle horizontally on the unpacking table, and the crawler unpacking machine is generally used for dismantling. Partial dismantling of its lining refractory materials may cause the collapse of refractory materials that do not need to be removed. The main reason is that the steel ladle is placed vertically to the masonry site and dismantled and dismantled by manual tools such as jacks and crowbars. The degree of automation is low. The efficiency is low, and the workers are in a high-temperature, high-dust working environment
