摘要
装载机属于铲土运输机械类,是一种通过安装在前端一个完整的铲斗支撑结构和连杆,随机器向前运动进行装载或挖掘,以及提升、运输和卸载的自行式机械。它广泛用于公路、铁路、建筑、水电、港口和矿山等工程建设。装载机具有作业速度快、效率高、机动性好、操作轻便等优点,因此成为工程建设中土石方施工的主要机种之一,对于加快工程建设速度,减轻劳动强度,提高工程质量,降低工程成本都发挥着重要的作用,是现代机械化施工中不可缺少的装备之一。
这次设计采用先进的现代设计方法,对这种轮式装载机工作装置进行了总体设计到零部件设计。主要包括轮式装载机工作装置的关键零部件,如铲斗、连杆机构以及转斗油缸、举升油缸等,并对重要零件进行了刚度、强度分析。应用CAD软件对轮式装载机工作装置整体进行设计,并用它对本次设计进行立体展示表达。
