装订线毕业设计（论文）报告纸摘 要随着人口老龄化问题的日益严重，老年人和残疾人的出行，在任何国家都会是一个问题。对这个问题解决的程度如何，反映着一个社会从科技水平到人文关怀等各方面的发达程度。但一直以来，现代许多工业化国家的交通运输部门对这种现状的重视程度还是不够即在交通工具上没有安装方便有行动障碍人士上下车的设施，这种现状存在着许多不和谐因素，更使群体分化加剧，社会人文关怀程度的下降。而在公交车上布置专用的残疾人蹬车门，并在此基础上装配残疾人轮椅升降系统具有方便行动不便人士上车的显著优点。例如:安全性好、机构简单、占地小、机械效率高、保密性好（指动力单元中液压元件）、寿命长、成本较低等。这些优点能够极大地反映着一个社会从科技水平到人文关怀等各方面的发达程度。实现行动不便人士蹬车无障碍化，并实现通过司乘人员，以及经过专门培训的人员对此套机构的简单辅助操作。首先应该从机构的可行性方案上进行深入讨论，通过对动力单元研究着手，然后经过反复细致的可行性，安全性分析以及对整个系统的运动校核，功能分析，而得到并形成系统的整体的结构，并且针对本系统的特点，来选择最适合的系统方案。因此，本文首先就方案的选择进行了研究。于设计者掌握的专业基础知识，互联网上的相关资料以及国内外已有的设计种类的现状，经过详细的方案调查，为本次毕业设计设计出了一套实用的兼用残疾人轮椅升降系统。本系统使用液压回路中的锁紧机构作为动力单元，采用十字叉式举升机构。论文方案选择的论证开始，详细介绍了方案分析、设计流程和计算流程，并进行了必要的动力系统总体结构设计、传力机构的设计校核等。主要用于实现对市内交通工具为满足行动不便的人士的升降平台的设计，实现对其能顺利上下车，进一步体现人文关怀。关键词： 兼用残疾人轮椅升降系统，升降平台，系统计算校核 ABSTRACTWe all know, its a problem for the senior citizen and the disable to go outdoor in any state How the problem is solved shows societys degree of progress from technology level to human concern. But for a long time, many modern industrialized country show little concern on the current transportation problem, they neglect to equip machinery for the disable to login in or out the bus. There exists some unharmonious problems in the phenomenon, it may cause the apartment for the public concentration and the reduction on the human concern. Equipping special door for the disable in the general distribution for the bus, and equipping elevating system for the disable on the basic of the door have advantages. For these advantages,safety,easy-operating,volum saving, high efficient, good package(hydraulic power unit),long using time and low cost is the prior concern for the manufacture and the public. These advantages greatly show the degree of progress from social technology to the human concern.To realize the no-disturb for the disable to login and the special trained servant to operate this set of machinery，we should first talk deeply about the feasibility of this machinery. Through the analysis on the power unit, the analysis on the feasibility ,safety, movement evaluating and the analysis of using afterwards, we establish the general structure, and we can also choose the suitable structure according to the system. Therefore, we first study the choose on the structure. Based on the knowledge, some file on the internet and the current state of the relevant machineries home and aboard, we have performed up-to-date study and design a set of elevating system for the disable to login on bus. This system uses hydraulic locking-current as the power unit and uses sole machinery for elevating. The paper begins with the argument on the general structure, and neatly introduce the structure analysis, design and calculating steps, and also performed some general structure design, power conducting machinery design and evaluating etc.Its widely used in the public transportation for any disable people, ensuring them to login on and out the bus convinently,and fatherly shows our progress on human concern.Key words: on-bus elevating system for the disablers login， elevating plate，layout目录1 前言-（1）2 系统开发方案说明2.1方案比较及选择-（8）2.2需要进行
