摘　　要：以上海梅山钢铁股份有限公司L201带式输送机(为带尾车升降机构堆取料机的场地皮带机)为研究对象,针对其在尾车升降过程中的恒张力控制需求,设计并计算了液压系统,并对泵、电机等关键功率器件进行了选型匹配。在此基础上设计了基于PLC的液压张紧控制系统,并利用参数自适应PID算法,实现尾车升降过程中的张力自适应控制。实际应用表明,本系统可以满足现场使用要求,张力控制误差不超过±2%。L201 belt conveyor with tail vehicle lifting structure in Shanghai Meishan Steel Co.Ltd.is researched in this paper.Aiming at the constant tension control requirements in the process of tail car lifting and lifting,the hydraulic system is designed and calculated,and the key power components such as pump and motor are selected and matched.On this basis,the hydraulic tension control system based on PLC is designed,and the adaptive PID algorithm is used to realize the tension adaptive control in the process of tail car lifting and lowering.The practical application shows that the system can meet the requirements of field use,and the tension control error is less than±2%.
