曲臂式高空作业平台和其液压系统设计.doc

摘要 高空作业车是将高空作业人员和必要的工具送至空中，并提供工作人员空中作业场所的机械。起重机是一种能在一定范围内垂直起升和水平移动物品的机械，动作间歇性和作业循环性是起重机工作的特点。 高空作业车主要应用于路灯、电力、交通、高速公路、造船修船、通信、建筑、园林、广告、机场、港口、有线电视等行业，使用面广、作业效率高、安全方便，拥有巨大的市场潜力。本课题主要是对其上车部分进行理论分析、计算并进行结构设计。 高空作业车是由两个机械臂组成，合理确定其一些基本尺寸，运用理论力学知识对其受力分析，用材料力学知识进行强度校核，确定其他尺寸。根据负载条件，选择液压元件，设计液压系统。运用绘图软件Pro-e , CAD，画出零件图和装配图。 关键字：起重机构；强度校核；液压系统；液压缸。 Abstract The aerial platform vehicle sends high rise operation personnel and the tool of the necessity to the air, and provide the staff member with the high rise operation amenity machine.The derrick is a kind of machine that cans be perpendicular in the certain scope to rise to rise to move a product with level, the action by fits and starts and the homework circulation are the characteristicses of the derrick work, can press the main use and the structure characteristic classification. It is widely used, efficient, safe and convenient. It has a great potential in the market. This article mainly finished the theoretical analysis, calculation and structure design . Aerial Work Platform is composed by two manipulators ,after reasonably determining some of its basic dimensions, making its force analysis according to theoretical mechanics, I use material mechanics knowledge to make its strength check, and decide the other dimensions. According to load conditions, I choose hydraulic components, design hydraulic system. Make use of the drawing software such as Pro - e, CAD, to paint parts graphs and assembly drawings. Keywords：jack mechanism； Strength check；Hydraulic system； fluid cylinder. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc355120712 1 绪论 PAGEREF _Toc355120712 \h 1 HYPERLINK \l _Toc355120713 1.1高空作业车简介 PAGEREF _Toc355120713 \h 1 HYPERLINK \l _Toc355120714 1.2 课题的来源和意义 PAGEREF _Toc355120714 \h 2 HYPERLINK \l _Toc355120715 1.3 国内外的发展状况 PAGEREF _Toc355120715 \h 2 HYPERLINK \l _Toc355120716 1.4 课题研究内容 PAGEREF _Toc355120716 \h 5 HYPERLINK \l _Toc355120717 2 折叠机构工作原理和计算分析 PAGEREF _Toc355120717 \h 6 HYPERLINK \l _To
