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CATIA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。

ABSTRACT

       Loader of soil belonging to the transport machinery，Through the installation of a front-end in a bucket full support structure and linkage, Random forward movement for loading or excavation, And the upgrading, transportation and unloading of self-propelled machinery. It widely used in highway, railway, construction, utilities, ports and mines, and other construction projects. Loader is operating speed, high efficiency, good mobility, the advantages of operating the Light, So as the construction of earth and stone in the construction of one of the main machine, speed up the construction speed and reduce labor intensity and improve quality, lower costs of the project has played an important role in the construction of a modern mechanized equipment indispensable one.
    The design of the modern use of advanced design methods, wheel loaders working on such a device design to design components. Wheel Loader work includes installation of critical components, such as the bucket, linkage and the fuel tank to the bucket, lifting the oil tanks, and carry out important parts of the stiffness, strength analysis. Application of CATIA software installed on the wheel loader work for the overall design and its use of this design three-dimensional display of expression.

Keywords：Loader； Mechanization；Work-Equipment
