摘要
针对某炼铁厂高炉底滤池无人化升级改造的切实需求,本文设计并研制了一套智能无人天车控制系统,在炼铁厂首次实现了抓渣转运全作业流程下的无人化运行。该系统主要包含天车电控系统、天车定位系统、地面设备控制系统、天车监控系统等,提出了一种新颖的基于双车联动的协同调度安全控制策略,基于线程技术控制天车合理执行等待、避让或移动等调度任务,首次实现同跨两台天车安全稳定协同调度。实践应用效果表明,改造后的炼铁厂高炉底滤池无人抓斗天车自动化和信息化程度高,抓斗运行平稳性、同步性、作业效率、满斗率等关键指标均优于人工操作,作业效率提升约20%,能耗下降约10%,劳动强度降低约70%。
In response to the practical need for unmanned upgrading and renovation of the bottom filter of a blast furnace in a certain ironmaking plant,this paper designs and develops an intelligent unmanned overhead crane control system,which has achieved unmanned operation under the full operation process of slag grabbing and transportation for the first time in the ironmaking plant.The system mainly includes the overhead crane electrical control system,overhead crane positioning system,ground equipment control system,overhead crane monitoring system,etc.A novel collaborative scheduling safety control strategy based on dual vehicle linkage is proposed.Based on threading technology,the overhead crane is controlled to reasonably execute scheduling tasks such as waiting,avoiding,or moving,achieving safe and stable collaborative scheduling of two overhead cranes across the same span for the first time.The practical application results show that the automation and informatization level of the unmanned grab bucket crane for the bottom filter of the blast furnace in the renovated ironmaking plant is high.Key indicators such as the stability,synchronization,operation efficiency,and full bucket rate of the grab bucket are better than manual operation.The operation efficiency is increased by about 20%,the energy consumption is reduced by about 10%,and the labor intensity is reduced by about 70%.
