双铰接剪叉式液压升降台的设计 摘要：双铰接剪叉式升降台的设计是在原由的剪叉式升降台的基础上，运用现在的灵活性、安全性、经济性等指标；结构以能够满足灵活性要求较高的汽车维修需要为前提,通过不同型号和响应福建达到满足物流、汽车维修等性能要求。 通过对双铰接剪叉式升降台机构位置参数和动力参数的技术，结合具体实例，对机构中良种液压缸布置方式分析比较，并根据要求对液压传动系统个部分进行设计计算最终确定液压执行元件-液压缸，通过对叉杆的各项受力分析确定台板与叉杆的载荷要求，最终完成剪叉式液压升降台的设计要求。 关键字：升降台；剪叉式 ；液压 Double-hinged scissors hydraulic lifting platform design Abstract: Double-hinged scissors lifts in the design of the previously scissors lifts on the basis of the present application flexibility, security, economic and other indicators, structural flexibility to meet higher requirements of vehicle maintenance the need for premise, and the response by different models to meet Fu jian logistics, vehicle maintenance, and other performance requirements.  Through the double-hinged scissors lifts Position parameter and the dynamic parameters of technology, combined with specific examples, the agency improved in the hydraulic cylinder layout analysis and comparison, and in accordance with the requirements of part of a hydraulic system design and calculation of final Pressure implementation components - hydraulic cylinder, through analysis of the fork-defined plate and fork-load requirements, the final completion of scissors hydraulic lifts the design requirements.
