摘　　要：旋挖钻机以其高效、环保的施工作业优势，已在桩工行业得到了广泛的应用。卷扬提放动作作为单个工作循环内最重要的动作之一，其工作效率及可靠性的高低，对旋挖钻机施工效率有着重要的影响。在后期的维护使用中，卷扬机构也是旋挖钻机故障最集中的地方，其电液系统的故障率较高。本文就以某型号旋挖钻机为例，对卷扬液压系统工作原理进行介绍，并对常出现的液压故障进行原因分析，提出解决方案。Hydraulic troubles and causes of an earth borer's winch system. Wind-in and wind-out is an important individual operation in a single working cycle of an earth-borer's winch, which would affect greatly operational efficiency of the borer, while the winch mechanism would be a concentration area of troubles in an earth boring apparatus. The text goes further to introduce working principles of the winch system while analyzing troubles and introducing counter remedies by putting forth troubles as an auger string slow sliding, stall sliding, and no floating functions with the main winch, for instance,which would have been caused by abnormal electro-hydraulic systems.
