摘 要 液压升降平台是一种广泛应用于工厂、商店、机关、码头、建筑装修行业的一种高空作业工具。本设计采用无线遥控，以提高设备操控的自化和灵活性。其次，本液压升降平台的四个支腿臂的内外伸缩臂设计采用液压缸驱动，节省了人力，提高了平台的工作效率。再者，本设计较一般液压升降平台改进之处是其升降高度采用传感器监控，提高了其升降的精度。最后设计过程采用有限元分析的方法，对零部件进行强度校核，优化了零部件的结构。 本设计采用逆向工程的方法，对现有的各种液压升平台比较分析，重点是在传统的结构设计的基础上加以有限元分析；改进一般液压升降平台的线控方式为无线电遥控方式，无线电遥控采用单路八通道遥控方式；在原有液压升降平台的基础上，改进人工拖动液压升降平台的支撑腿为液压缸驱动。 关键词：液压升降平台；无线电遥控；有限元分析；传感器 Abstract A hydraulic lifting platform is a tool for high-altitude operations that is widely used in factories, shops and offices, terminals, building decoration industry .The design of a wireless remote control is to enhance the self-control equipment and flexibility. Finally, designing process use finite element analysis, to check the strength of parts and components, and to optimize the structure of the parts. Secondly, the four outrigger arm of the hydraulic lifting platform use the design of the internal and external telescopic boom driven by hydraulic cylinders, saving human resources, improving the efficiency of the platform. Furthermore, the improvement of the design of the hydraulic lifting platform is that sensors monitor is used to accurate the height of platform and improve the accuracy of their movements. This design uses the method of reverse engineering and comparing with the various existing hydraulic platform or , focusing on the traditional design of the structure on the basis finite element analysis, the general improvement of the hydraulic lifting platform for radio-controlled wire way. A radio-controlled remote control one-way four-lane way in the original hydraulic lifting platform on the basis of improving the artificial drag hydraulic lifting platform for the support legs hydraulic cylinder drive. The design has achieved the desired effect,has a bright market prospects Keywords: hydraulic lifting platform; radio control ;finite element analysis; sensors monitor 目录 摘 要 I Abstract II 1 绪 论 1 1.1液压升降平台在机械工业中的应用及相关技术概况 1 1.1.1 传感技术 2 1.1.2 遥控技术 2 1.1.3 有限元分析技术 3 1.1.4 液压传动技术 4 1.1.5 液
