中文摘要
采煤综合机械化，是加速我国煤炭工业发展，大幅度提高劳动生产率，实现煤炭工业现代化的一项战略措施。综合机械化不仅产量大，效率高，成本低，而且能减轻笨重的体力劳动， 改善作业环境，是煤炭工业技术的发展方向。液压支架是综合机械化采煤方法中最重要的设备之一。
液压支架主要由以下几个基本部分组成：顶梁，掩护梁和四连杆机构，侧护板，底座，立柱，千斤顶。设计要遵从支护性能好、强度高、移架速度快、安全可靠等原则。
在支撑掩护式的设计过程中，前梁、主顶梁、掩护梁和立柱等结构件的设计是重点。本论文介绍了液压支架的结构，类型，工作原理，特点，目的及要求，对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。
关键词：液压支架骨刺灵>金属包覆垫片 支护 四连杆机构顶梁 掩护梁 液压支柱或者支柱
Abstract
Hydraulic Support
The comprehensive mechanization of coal mining is the acceleration coal industrial devel
opment of our country , raises labor productivity substantially , realizes the modern a strategic measure of coal industry. Synthesize mechanization not only output big, efficiency has low cost high and can alleviate heavy physical labor and improvement schoolwork environment, is the technology of coal industry develop direction. Hydraulic support is the one of comprehensive most important equipment in the mechanization method of coal mining.
Hydraulic support major from some following basically partial compositions: Top beam, screens beam and 4 linkage mechanisms, side fender, base, prop. Design to follow protect performance good, strength is speed high, move rapid, safely reliable etc. principle.
In the design course that the type of supports cover type, the design of canopy and caving shield and props is key. This paper has introduced requirement, type, working principle, characteristic, purpose and the structure of hydraulic support, for screening type hydraulic pressure support have made detailed analysis and introduction, have narrated use and the scheme of this kind of support.
Keyword: hydraulic support shoring 4 linkage mechanisms canopy caving shield hydraulic legs or props
