内容简介：

中国矿业大学2007届本科生毕业设计 第 II页摘要掩护式支架作为上世纪70年代初刚出现的产品，其显著特征是在顶梁末端和底座之间附加有掩护梁。掩护梁一般是倾斜的，铰接在顶梁和底座之间。从运动学讲，它是稳定的，这是掩护式支架最优于框式支架和垛式支架的一点，掩护梁也完全封闭了采空区，从而能够防止破碎顶板岩石掉入支撑工作面。因此，一般来说，掩护式支架的支撑工作面是较清洁的。本文主要介绍了：液压支架的发展历程及发展趋势；液压支架的组成、作用和分类；液压支架的液压控制系统；液压支架设计的一般步骤；液压支架的操纵、维护、故障分析及处理等。在ZY8600型液压支架的设计过程中，着重对顶梁、底座和立柱进行了分析和设计，同时对液压支架的液压系统进行了介绍。根据其常见失效形式、影响因素及基本设计要求，给出了重要结构件的受力分析、强度和刚度的设计方法。在该支架的四连杆机构设计中，采用了计算机求解。对立柱和平衡千斤顶进行了强度和稳定性效核。关键词：液压支架、ZY8600、掩护式、结构设计、采煤机械ABSTRACTStand cover of the last century as the early 1970s emerging products, the notable features of the top beam between the terminal and the base of attaching a shield. Cover is generally inclined beams, the hinged roof beams and between the base. Kinematics from the speakers, it is stable, which is the optimal shield in the box-stent and the stent Crib 1:00, Leung also cover is closed goaf, so as to prevent the rock into the broken roof support Face. Therefore, in general, cover Stand Face the support of the cleaner. This paper describes : hydraulic supports the development process and development trends; Hydraulic support the composition, role and classification; hydraulic supports the hydraulic control system; hydraulic supports the general design steps; hydraulic supports manipulation, maintenance, Fault analysis and processing. In ZY8600-hydraulic support the design process, focusing on the top beam and column base and the analysis and design Meanwhile hydraulic supports the right hydraulic system was introduced. According to their common failure mode, influencing factors and basic design requirements, is an important structure the force. Strength and stiffness of the design method. The stent in the four-bar linkage design, using a computer to solve. Column right balance between Jack and the strength and stability of nuclear
