摘　　要：对PZL2000/310履带式转载破碎机的刮板运输用套筒链在某矿使用寿命不足的原因进行了分析。经理论分析,整机运输系统动力参数满足设计指标。经测试实验分析,套筒链拉伸性能满足设计指标,链板表面硬度低于设计值10%左右。链板磨损后导致抗拉能力降低是导致链条断裂的主要原因。将链板轮廓由凹底改进为平底形,改进后使用寿命寿命提高约65%。针对不同的使用工况,给出了对应的设备配套方案。The causes for the insufficient service life of sleeve chain used for scraper transport of the PZL2000/310 track type transfer crusher in a certain mine were analyzed.Through theoretical analysis,the dynamic parameters of the whole transport system meet the design index.Through test analysis,the tensile properties of sleeve chain meet the design index,and the surface hardness of the chain plate is about 10%lower than the design value.The main cause of chain breakage is the decrease of tensile capacity caused by the wear of the chain plate.The outline of the chain plate was improved from concave bottom shape to flat bottom shape,and the service life is increased by about 65%after the improvement.According to different working conditions,the corresponding equipment matching scheme was given.
