摘 要:结合刮板输送机的结构特点,通过建立刮板链与链轮的动力仿真模型,开展了刮板链断链故障过程的运动分析,找到了刮板链发生断链过程中的速度和接触力变化规律,并由此提出了防止刮板链断链的改进建议。该研究对降低刮板链断链故障率、延长刮板链使用寿命、提高刮板输送机的工作效率具有重要意义,可为煤矿企业对刮板链部件保护提供指导。According to the structural characteristics of scraper conveyor,the dynamic simulation model of scraper chain and sprocket is established,and the movement analysis of broken chain failure process of scraper chain is carried out.The change rule of speed and contact force in the process of chain breaking of scraper chain is found out,and the improvement suggestion to prevent chain break of scraper chain is put forward.This study is of great significance in reducing the failure rate of scraper chain,prolonging the service life of scraper chain and improving the working efficiency of scraper conveyor.It can provide guidance for coal mine enterprises to protect scraper chain components.
