1、 ZL 系列轮式装载机 2013 年 6 月 I 摘要 装载机是一种重要的土石方施工机械，普遍应用于铁路、公路、建筑、港 口、水电、矿山等建设工程。它的主要作用是铲装石灰、砂石、碎屑、土壤、 煤炭等散状物料，同时也可以对硬土、矿石等作一定程度的铲挖作业。装载机 拥有操作轻便，效率高，机动性好，作业速度快等一系列优点，在加快工程建 设的速度，降低工程的成本，提高工程的质量，减轻劳动的强度等诸多方面都 起着非常重要的作用，因此成为现代机械化施工中非常重要的机械装备之一。 轮式装载机是由动力装置、传动系统、行走装置、液压系统、转向系统、 制动系统和工作装置等诸多系统组成。由于工作装置的合理科学性直接
2、影响着 装载机的生产效率、动力特性、运动特性、发动机功率、各工况下的作业效果、 工作负荷、工作循环时间、外形尺寸等诸多因素，因此，装载机工作装置设计 的合理性和科学性对装载机的整体性能有至关重要的影响。 轮式装载机的工作装置主要由铲斗，动臂，摇臂，连杆，动臂油缸和转斗 油缸组成。科学合理的设计并校核这些零部件，才能最终设计出结构和工作性 能合理的装载机工作装置。 关键词：装载机，施工机械，工作装置，设计，校核 II ABSTRACTABSTRACT Loader is a kind of important earthwork construction machinery, widely us
