毕业设计论文-滚轮式脚踏式液压升降平台车设计液压机电 Roller-type hydraulic lifting platform pedal car design Abstract ：This issue is roller-type hydraulic lifting platform pedal car design for places such as factory and machine shop for cargo handling , it is a inevitable product in industrial production.This machine is posed by high-quality steel ,hydraulic cylinder ，hydraulic pump，pipeline, casters and so on.It can replace the heavy manual labor，significantly reduce labor intensity and improve working conditions and raise the level of labor productivity and automation. 　The biggest load of this snorkel described in this article is 500kg and the platform consists of two parts: body and the hydraulic system lift .The operation and control of the snorkel are completed by a set of hydraulic systems and hydraulic cylinders，also the combination of all of the hydraulic system are stored in the hydraulic pump .Both hydraulic pumps and hydraulic cylinders are standard, the former is a single hydraulic cylinder and the later is Pedal type。firstly，This article expound the required imum pressure the hydraulic cylinder bear that need to up the goods through the support of the hinge force analysis .according to this，the standard and model choice of the hydraulic pump, hydraulic cylinde are determined，And it describes relevant hydraulic system principles and account oil volume of the hydraulic pump.In addition, this paper check the strength of the hinge frame and the axes at both ends of the Hydraulic cylinder by mainly using the mechanics of materials knowledge ，Finally, check the weight and cost of this lifting platform .This Graduation Project have refer from a large amount of information and national standards, it fully absorbed the valuable experience of experts in all walks of life. Key word:Pedal-style platform hydraulic pump hydraulic cylinder hydraulic system standard parts cost accounting 　　　　　　　　　 Signature of Supervisor: 　目 录 1 绪论 1.1 课题研究的目的及意义 1 1.1.1滚轮式脚踏式液压升降平台车设计的目的 1 1.1.2滚轮式
