1、JIUJIANGUNIVERSITY毕业设计题目液压毕业设计英文题目Hydraulicgraduatiandesign院系机械与材料工程学院专业机电一体化姓名崔海涛年级2011(机材B1121)指导教师张为二零一三年十二月摘要ZY3200/14/34掩护式液压支架的设计,主要是针对冀中集团梧桐庄矿22313工作面的煤层、围岩情况及其配套设备进行选型设计的一种实用液压支架。通过介绍整个矿井的地质条件及工作面的实际情况,结合支架的发展情况及分类,对液压支架进行了选型,并确定其基本技术参数。根据结构部件在整个液压支架中承载情况及作用,详细对支架的顶梁、四连杆机构、侧护板、底座、立柱
2、、各种千斤顶等部件进行了结构设计,确定了其整体结构尺寸。重点对立柱做了结构、技术参数说明,并根据其承载的工作阻力对立柱的稳定性,活塞杆和缸体的强度进行了校验。介绍了该支架液压系统的特点,详细说明了立柱、各种千斤顶系统的基本控制回路及它们的工作原理,并对泵站液压元件、液压管路进行了选型。【关键词】掩护式液压支架;结构部件;液压系统AbstractThedesignZY3200/14/34cover-poweredsupportismainlyforXingtaiMiningGroup,Xingtai22313faceofthecoalmine,anditssurrounding
