河南理工大學(xué)畢業(yè)設(shè)計論文 支撐掩護式液壓支架 中文摘要 采煤綜合機械化，是加速我國煤炭工業(yè)發(fā)展，大幅度提高勞動生產(chǎn)率，實現(xiàn)煤 炭工業(yè)現(xiàn)代化的一項戰(zhàn)略措施。綜合機械化不僅產(chǎn)量大，效率高，成本低，而且能 減輕笨重的體力勞動，改善作業(yè)環(huán)境，是煤炭工業(yè)技術(shù)的發(fā)展方向。液壓支架是綜 合機械化采煤方法中最重要的設(shè)備之一。 液壓支架主要包括以下幾個基本部分組成：頂梁，掩護梁和四連桿機構(gòu)，側(cè)護 板，底座，立柱，千斤頂。設(shè)計要遵從支護性能好、強度高、移架速度快、安全可 靠等原則。 在支撐掩護式液壓支架的設(shè)計過程中，四連桿機構(gòu)和底座結(jié)構(gòu)件的設(shè)計是重點。 本論文介紹了液壓支架的結(jié)構(gòu)，類型，工作原理，特點，目的及要求，對支撐掩護 式液壓支架作了詳盡的分析和介紹，講述了這種支架的方案和用途。另外，對液壓 支架的結(jié)構(gòu)性能、受力狀況和如何選型等進行了分析，同時介紹了液壓支架的使用、 維修和故障排除等問題。 關(guān)鍵詞：液壓支架 支護 四連桿機構(gòu)底座 河南理工大學(xué)畢業(yè)設(shè)計論文 ABSTRACT Hydraulic Support The comprehensive mechanization of coal mining is a strategic measure to the acceleration coal industrial development of our country , raise labor productivity substantially , realize the modern 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 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 support. Furthermore, the structure of hydraulic structures performance, the power situation and how to choose models are analysed, at the same time it introduces the use of hydraulic Support, maintenance and fault resolution and other issues. Keywords: hydraulic support shoring 4 linkage mechanisms base
