文档介绍：新乡职业技术学院毕业设计(论文) 题目液压升降平台系别机电工程系学生姓名赵帅宇学号 1********** 专业名称机电一体化指导教师王磊、魏海云 2015 年 12月 10日摘要本次毕业设计对象是液压升降平台,这套装置主要用于举升重物。其动作主要是由液压缸推动“X”型架,带动上板来实现的。该液压升降平台主要由两个部分组成: 机械部分和液压部分,其中机械部分主要由上板架、下板架、内连杆和外连杆四部分组成。本设计设计、选择了机械部分材料与结构,并对其进行受理分析与校核,以便检验是否满足强度、刚度的要求,分析及校核的结果证明机械结构的设计可以满足要求。在对液压控制系统的设计过程中,先进行了总体方案设计。关键词: 液压;升降平台;上板架;下板架;内连杆;外连杆 Ab stract I graduated from the current design isdone mainly hydraulic lifts, mainly divided into two parts: mechanical and hydraulic parts. Mechanical parts which I think the main needs tobe considered is the subject of several major part of the intensity: on board planes, under the board planes, within and outside link connecting rod. In this part of my four were on board from top to bottom-line Analysis of the internal and external linkage, I had the strength check. After my analysis and after checking I think I can satisfy the design requirements. Then I entered the various parts of the hydraulic choice. In the choice of the hydraulic control circuit all the time, in the loop parison of the governor after I selected the import speed loop circuit; unloading loop I chose the valve of the unloading circuit; packing circuit I have chosen The use of one-way valve controlling the packing circuit. In determining the needs of the various circuit I, I'm sure I wear the hydraulic system of fixed form, according to open-system and the system simple cooling system features good condition, I set my drive system for open - System. On the other ponents accessories choice, I had to them after the calculation of the hydraulic cylinders after I voted 45 mm of hydraulic cylinders, according to the transmission gear pump stability, I take my pump asa gear Pump, according to my system the maximum power of the work I elected to the motor Y112M-4 to three-phase asynchronous motor. I set the pump, I also based on this I need the yuan other accessories for a reasonable Choose, finally, I identified a variety ponents, plete the design of the topics I. Keywords :
