宁钢混匀料场桥式双斗轮取料机经过3年多的使用,发现设备故障率偏高,取料能力偏低,严重影响原料的后续作业流程.通过对设备实地调研并结合已有故障分析,发现主要的故障点集中在桥架梁刚度偏低、小车车体变形和料耙结构不合理等几个方面,针对以上几方面存在的问题,结合实际并借鉴已有的成功经验对设备的机构本体进行分析优化、局部进行改型,从根本上提高了设备的工作稳定性和作业能力,极大地减少了设备的维护成本;同时本次改进对该类设备的换代升级有很大的借鉴意义.“,”After 3 years application of the mixing field bridge type double bucket wheel reclaimer in Ningsteel,it was found that the equipment failure rate was relatively high,and the reclaiming rate was relatively low,which seriously affected the subsequent work flow of the raw material.Based on the research of the device owsite and the existing fault analysis,it can be pointed out that the defaults concentrated in several areas where the stiffness of bridge beam was lower,the skip body was deformed,or the rake structure was improper.Additionally,based on the problems mentioned above,the equipment was analyzed and optimized and the parts of the device was improved by combining the practical application with the existing successful experiences.As a result,it fundamentally enhanced the working stability and capability of the device,and dramatically reduced the maintenance cost of the device,and can be used for reference in the optimizing and upgrading of the similar devices.
