毕业设计（论文）-汽车清障车设计.doc

1 - 摘 要 随着人们生活水平的提高，汽车也走进了人们的生活当中，走进了家家户户。因此由于道路上车辆的增多，车辆之间发生的事故，车辆发生故障以及违规停车的现象也越发的频繁。通过查找资料对现有的汽车清障车的了解，大多数的清障车的清障方式为拖拽且只能由被拖车辆的前面进行操作。这种方式在特殊的情况特别是前方有障碍物的情况下尤为不便。 本文通过设计一种可调节支腿的汽车吊架，结合改造的汽车起重机配合使用，达到在多种环境下都能对事故及违规车辆进行清除的新型汽车清障车。文中将对汽车清障车的起升机构、回转机构、起重臂以及吊架和可调支撑进行介绍及设计。最后使用Solidworks三维软件及AutoCAD二维绘图软件对设计的内容进行三维的建模及二维装配图及零件图的绘制。 关键词: 起升机构;起重臂;回转机构;清障车；可调支腿 全套图纸加扣 3346389411或3012250582 Abstract With the improvement of people’s living standards, cars have also entered the lives of people and entered every household. Therefore, due to the increase of vehicles on the road, accidents between vehicles, vehicle failures and illegal parking are becoming more and more frequent. Through the search for information on the existing car wrecker, most wreckers are dragged and can only be operated by the front of the dragged vehicle. This method is particularly inconvenient in special situations, especially when obstacles are in front of you. This paper designs a new type of automobile wrecker that can adjust the outriggers and use it together with the modified auto cranes to achieve the elimination of accidents and illegal vehicles in various environments. The paper will introduce and design the hoisting mechanism, swing mechanism, lifting arm, hanger and adjustable support of the wrecker. Finally, using Solidworks three-dimensional software and AutoCAD two-dimensional drawing software to carry out three-dimensional modeling of the contents of the design and the two-dimensional assembly drawings and parts drawing. Keywords: Lifting mechanism; Lift arm; Slewing mechanism; Wrecker; Adjustable outrigger 目 录 TOC \o 1-3 \h \z \u 摘 要 - 1 - 目 录 - 3 - 1绪论 - 4 - 1.1 课题研究的目的和意义 - 4 - 1.2国内外现状 - 4 - 1.3发展趋势 - 5 - 1.4课题设计内容 - 6 - 2起升机机构设计 - 7 - 2.1 起升机构的基本参数计算 - 7 - 2.1.1 传动方案 - 7 - 2.1.2基本参数的计算 - 7 - 2.2钢丝绳的设计与选用 - 9 - 2.3吊钩的设计与选用 - 10 - 2.3.1选材 - 10 - 2.3.2构造 - 10 - 2.3.3吊钩挂架 - 10 - 2.3.4横
