剪叉式液压升降平台的结构形式种类繁多，从升降方式看，他有低升起和高升起。剪叉臂杆的数目多，油缸的布置形式多：移动方式有自动式、助力式、移动式等等。从组成方式看，剪叉式液压升降台主要由底座、剪臂结构、工作平台三部分组成。
本课题注重安全可靠性，因此有些问题由此展开。液压升降机的机械结构通常是由底座，臂架以及工作台几部分组成。各个地方的设计首先要达到足够的强度和刚度，才开始展开其他方面的合理设计。本课题主要设计机械结构，液压系统和驱动控制部分。从安全性，可靠性的角度看，液压升降机不同于一般机械，其特点是作业频率不高，负荷较小，但要求安全性，可靠性高。因此，为保证高空作业车的工作稳定、可靠性、安全、作业灵活、效率高、设计出优良额机械结构和液压系统。
本课题主要设计要求和所需要的参数如下：
1、最大载荷1500kg
2、升降高度为10m
经过一段时间的努力收集资料，研究工作取得了一些成果，个人也在这方面的经验有所提升。因此能够很好的进行研究工作。另外，学校的图书馆拥有大量的收藏图书资料，以及足够数据库资源，本人可以高效率的查阅资料。而且我的指导老师有液压实验室、电脑机房、机械制造工作室。也为本课题的研究工作进行提供了坚实的物质基础和实验条件，从而确保了自己的课题顺利结束。
毕业论文关键词：液压升降机，安全可靠，作业灵活
Abstract
Hydraulic pneumatic fluid as the working medium is based on the energy of a drive in the form of transfer control. It is a new technology. In recent decades, the rapid development of microelectronics and computer technology, hydraulic technology also benefit. After the combination of new computer technology, the field of use in various industries and popular acclaim. Has become an important way to achieve production automation, improve efficiency.
Structure scissors hydraulic lifting platform has a wide range of types.
From lifting way to see, it has a low rise and high-rise.In ateetion, There are a number of multi-arm scissors and multi-cylinder arrangements. The way of moving like automaticing, assisting-move, mobile-moving, etc. Look from the composition, Scissor lifts mainly cosists of the base , cut arm structure and work platform three-part.
The emphasis foucus on security and reliability issues, because of what some problems come to be solved. Mechanical construction of the hydraulic lift is usually from the base, arm and table several parts. Various parts of the design of the first to achieve sufficient strength and rigidity, rational design began to expand in other areas. This topic mainly designed mechanical structure, hydraulic system and drive control section. From the perspective of safety and reliability to see, mechanical hydraulic lifts doesn’t like general machinery. It is characterized by low operation frequency and the light rad.But it requires good security and high reliability. Therefore, to ensure the stability, reliability and safety of aerial job, to design a good amount of mechanical structures and hydraulic systems. The main subject on design requirements and the required parameters are as follows:
1.Maximum load is 1500kg
2.Lifting height is 10m
After a period of efforts to gather information, research yielded some results. Personal experience in this area also has been improved. It is possible to carry out research work well. In addition, the school library has a large collection of books and materials. I can easily access to information. And my instructor has hydraulic laboratory, computer room, machinery manufacturing studio. Oriented research topics also conducted to provide a solid material foundation and experimental conditions. Thus ensuring the successful completion of my design work.
