摘要装载机主要用来装卸成堆散料，也能进行轻度的铲掘工作。由于它适用于建筑、矿山、铁道、公路、水电等国民经济各个部门，因此，在国内外，产量与品种的发展都较快，是工程机械中的一个主要机种。

装载机根据不同的使用要求，发展形成了不同的结构类型。通常，按使用场合的不同，分成露天用装载机和井下用装载机；按行走系统结构不同，分成轮式装载机与履带式装载机；按卸料方式不同，分为前卸式、后卸式与回转式装载机。

毕业设计论文对装载机的发展概况及设计的指导思想、特点、任务进行概述，然后确定方案，在技术设计部分罗列了现有装载机的主要技术性能和参数，进行了牵引特性计算。工作装置进行设计，包括它的铲斗的选择包括：结构形式，具体参数，铲斗容量。然后进行的是其连杆机构的设计包括动臂的一些数据计算以及连杆机构中一些组件的尺寸，以及工作装置的强度的计算，采用受力分析法进行计算分析，最后进行装载机工作装置的设计。49700

Abstract Piles mainly used for loading and unloading bulk material loading machine, but also for mild shovel. Because it is used in construction, mining, railway, highway, water and electricity of each department of national economy, therefore, at home and abroad, the development of production and variety are faster, is a main kind of Engineering machinery.

Loader according to different requirements, develop and form a different structure types. Usually, by the use of different occasions, into the open hole with a loader and loader; according to the running system, pided into the wheel loader and crawler loaders; by discharge in different ways, into the former dump (front), after unloading type and rotary type loader.

Graduation thesis this first loader development of guiding ideology, characteristics, task of survey and design, and then determine the scheme, in the technical design part of the main technical performance and the parameters of the existing loader is presented, the calculation of the tractive characteristics. Design of working device, including its bucket selection include: structure, specific parameters, bucket capacity. Then is to include some component size data computing boom and linkage design of the linkage mechanism, calculation and working device of the strength, the analysis method for the calculation of stress analysis, the final design of working device of loader.

Keywords: loader, working , swing arm , connecting rod, rocker arm
