掩护式液压支架
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。
在掩护式液压支架的设计过程中,整体伸缩式顶梁和立柱的设计是重点。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。
关键词:液压支架支护四连杆机构
Abstract
Hydraulic Support
prehensive mechanization of coal mining is the acceleration coal industrial development 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 prehensive most important equipment in the mechanization method of coal mining Hydraulic support major from some following basically positions: 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 4 linkage mechanism ,base ,structural member 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 supportKeyword: hydraulic supportshoring4 linkage mechanisms
