【机械工程及自动化】SRC型旋挖钻机的液压系统设计.docx

毕业设计SR200C型旋挖钻机的液压系统设计院系： 机械学院 设计完成时间：2015年6月摘要不知不觉大学四年快要结束了，这次的毕业设计是我在这四年大学的一个检验，我做的是旋挖钻机的液压系统，在这次设计之前，经过老师的指导以及各种途径的查找资料，我首先确定了选型，知道了旋挖钻机的用途，并把旋挖钻机的型号定为SR200C，然后查找并研究了旋挖钻机的发展历程以及国内外的发展状况，让我对旋挖钻机有了进一步的了解，接下来开始对SR200C型旋挖钻机的设计，先确定旋挖钻机的整机布置，并确定设计参数，然后进行工况分析，钻进的工况分析，卷扬工况分析以及变幅和行走工况分析，接着设计回路，有泵控回路，动力头回转回路，加压回路，主、副卷扬回路，变幅回路，行走回路，然后是各种液压马达的计算，动力头，主卷扬，副卷扬，还有行走马达。设计液压系统少不了对液压缸的设计，旋挖钻机有3个油缸，分别是，加压油缸，动臂变幅油缸，钻杆变幅油缸，然后我选择确定泵的流量和工作压力，接下来确定主油管的管径，然后确定油箱的容量，然后进行系统的功率损失验算以及温升验算，最近进行旋挖钻机的技术与经济分析得出结论。然后开始绘图，整个设计从开始的选型到最后的绘图，让我对旋挖钻机有了一定的认识与了解，也增强了我的自主学习的能力。AbstractUnconsciously at the university of four years coming to an end, this is my graduation design in these four years at the university of a test, I do is rotating drill hydraulic system, before this design, through the guidance of the teacher as well as a variety of ways to find information, I first determine the selection, know the purpose of the rotating drill, and the rotating drill model as SR200C, then find and study the development course of the rotating drill and development situation at home and abroad, let me have a further knowledge of rotating drill, then start to the design of type SR200C rotating drill, first determine the rotating drill machine layout, and design parameters were determined, and then working condition analysis, analysis of working conditions of drilling winding condition analysis and the analysis of the working condition of amplitude and walking, and then design circuits, pump control circuits, power head rotation loop, pressure loop, Lord, vice winding circuit, transformer circuit, circuit, and then the calculation of various hydraulic motors, power head, the main winding, winding, walking and motor. Design necessary for the design of the hydraulic cylinder, hydraulic system has three rotating drill oil cylinder, respectively, pressurized cylinders, movable arm luffing cylinder, transformer oil cylinder rod, and then I choose work to determine the pump flow rate and p
