工作装置作为装载机的核心组成部件,其工作性能的好坏将直接影响到整个装载机的工作效率和经济性指标。针对装载机工作装置出现的拉杆弯曲、铲斗收斗不到位两种故障进行了分析,充分考虑了用户利用“靠挡块功能”等操作习惯和不同的个性操作对拉杆弯曲、铲斗收斗不到位的影响,细化工作装置的铲掘、卸料、收斗、举升和运输等不同工况的极限位置及转接过程中拉杆等的受力分析,按照机-液结合的整机系统思考方法,提出一种液压泄荷阀调整的经验方法,可有效地防止拉杆弯曲的两种工况发生。尤其是在两种故障关联处的摇臂与动臂座梁之间焊接卸载限位块,既防止了拉杆受弯,又避免了铲斗与动臂间的冲击,保证了收斗角的稳定,有效解决了上述两类问题。通过近三年时间的市场验证,收到了良好效果。
As the core component of loader, the working device will directly affect the working efficiency and economic index of the entire loader. In view of the emergence of the loader working device bending rod, bucket bucket is not in place two kinds of failures were analyzed, taking full account of the user “by the stopper function ” and other operating habits and different personality of the operating lever bending, bucket Fighting is not in place, the refinement of the work of the device excavation, unloading, fights, lifting and transportation and other conditions of the extreme position and the transfer process of the rod and other force analysis, in accordance with the machine - liquid combination The whole system thinking method, put forward an experience of hydraulic pressure relief valve adjustment method, which can effectively prevent the two bending rod conditions occur. Especially in the two fault correlation between the rocker and boom seat beam welding unloading limit block, both to prevent the rod bending, but also to avoid the impact between the bucket and boom to ensure the stability of the bucket corner , Effectively solve the above two issues. After nearly three years of market validation, received good results.
