摘要:為了滿足對(duì)煤炭日夜增長(zhǎng)的需要，必須大量生產(chǎn)綜合機(jī)械化采煤設(shè)備，迅速增加綜合機(jī)械化采煤工作面。因此，液壓支架的性能決定了整個(gè)綜采的進(jìn)度與安全，從而對(duì)液壓支架的液壓系統(tǒng)的的設(shè)計(jì)成了液壓支架設(shè)計(jì)的重要部分。

　　　本論文主要闡述了掩護(hù)式液壓支架的液壓系統(tǒng)的設(shè)計(jì)過程，另外也對(duì)液壓支架中的主要部件做了設(shè)計(jì)。設(shè)計(jì)過程中根據(jù)液壓支架的工作要求和工作條件，充分利用液壓設(shè)計(jì)手冊(cè)軟件簡(jiǎn)明、方便的特點(diǎn)，在完成相關(guān)的設(shè)計(jì)分析、計(jì)算后，綜合出較優(yōu)的液壓系統(tǒng)原理，并對(duì)相關(guān)液壓元件的參數(shù)選擇以及整個(gè)液壓系統(tǒng)的性能進(jìn)行驗(yàn)算，然后通過CQYZ-M/C1智能化測(cè)控液壓系統(tǒng)實(shí)驗(yàn)臺(tái)進(jìn)行驗(yàn)證，在實(shí)驗(yàn)成功的基礎(chǔ)上，繪制出液壓系統(tǒng)原理圖。本論文中對(duì)液壓支架的設(shè)計(jì)內(nèi)容如下：

ABSTRACT:In order to meet the need for coal increased day and night, to mass production of fully mechanized coal mining equipment, rapid increase in comprehensive mechanized coal face. Therefore, determines the performance of the entire hydraulic support in fully mechanized progress and security, thereby contributing to the design of hydraulic system of hydraulic support became an important part of the design of hydraulic support.

　　　 Mainly on the thesis cover design for hydraulic system of hydraulic support process, and agency and in powered support major parts to do a certain amount of design. Design process in the under hydraulic bracket of work requirements and work conditions, full using hydraulic design manual software concise, and easy of features, using machinery system design of views in completed related of design analysis, and calculation Hou, integrated out more excellent of hydraulic system principle, and on related hydraulic components of parameter select and entire hydraulic system of performance for checking, and by CQYZ-M/C1 intelligent of measurement and control hydraulic system experimental Taiwan for validation, in experimental success of Foundation Shang, draws out hydraulic system principle figure; And complete cylinder Assembly Drawing.   In this paper on the design of hydraulic system of hydraulic support as follows: 

　　　Chapter I, powered and designed for hydraulic support overview. 

　　　Chapter two shield-type powered support institutions and the major part of the design. 

　　　According to the job requirements, support the environment, on the support of four-bar linkage and cover support beams, girders, base, and other major parts of design. 

　　　Chapter three on the cover design of hydraulic support column and other Jack. According to the given parameters and initial conditions, completed on column design of hydraulic cylinder and the other Jack. 

　　　Cover of the fourth chapter on design and calculation of hydraulic system for hydraulic powered support. 

　　　Under bracket that needs to be done, determining the hydraulic system of circuit, to the development of hydraulic system schematics and checking calculation of complete hydraulic systems.
