内容简介：

中国矿业大学2009届毕业生毕业设计 第 3 页摘 要本论文设计的是关于5-10米煤层、倾角小于18，煤质硬度f=13的支撑掩护式液压支架和液压系统中的重要组成部件立柱的设计。 该液压支架主要有以下几个基本部分组成：顶梁、掩护梁、前、后连杆、侧护板、底座、推杆和立柱、千斤顶。设计主要遵循支护性能好、强度高、移架速度快、安全可靠等原则。本论文介绍了液压支架的发展，工作原理和分类，对支撑掩护式液压支架作了详尽的分析和介绍，讲述了这种支架的方案和用途。另外，对液压支架的结构性能和如何选型等进行了分析，同时介绍了液压支架的运输、安装、使用和维护等方面的知识。该支架适用范围很广，可用于各种顶板条件、尤其适用于中等稳定以上的顶板条件和大采高的条件。关键词：液压支架 支护 四连杆机构 底座AbstractIn this paper, the design is about 5-10 meters of coal, the inclination is less than 18 , coal hardness f = 1-3 to support the cover-powered support and the hydraulic system is an important component parts - the design of the column.The hydraulic support mainly in the following basic parts: the top beam, beam cover, before and after the connecting rod, the side of the shield, base, and putting column, Jack. Follow the design of the main support good performance, high-intensity, Moving fast, safe and reliable principles.This paper describes the development of the hydraulic support, and the principle of classification, support for the cover-powered support a detailed analysis and presentation about this program and the use of stents. In addition, the hydraulic support for the structure of the performance and how the selection were analyzed at the same time introduced the hydraulic support of transportation, installation, maintenance and use of knowledge.The applicable Stent range can be used for a variety of roof conditions, in particular, apply to the stability in the middle of the roof above the conditions and l
