摘要:为了满足对煤炭日夜增长的需要，必须大量生产综合机械化采煤设备，迅速增加综合机械化采煤工作面。因此，液压支架的性能决定了整个综采的进度与安全，从而对液压支架的液压系统的的设计成了液压支架设计的重要部分。

　　　本论文主要阐述了掩护式液压支架的液压系统的设计过程，另外也对液压支架中的主要部件做了设计。设计过程中根据液压支架的工作要求和工作条件，充分利用液压设计手册软件简明、方便的特点，在完成相关的设计分析、计算后，综合出较优的液压系统原理，并对相关液压元件的参数选择以及整个液压系统的性能进行验算，然后通过CQYZ-M/C1智能化测控液压系统实验台进行验证，在实验成功的基础上，绘制出液压系统原理图。本论文中对液压支架的设计内容如下：

　　第一章 液压支架的设计目的以及对液压支架的概述。 

　　 第二章 对掩护式液压支架支架中的结构和主要部件的设计。

　　根据支架的工作要求、环境，对支架的顶梁、掩护梁、底座、前后连杆等主要部件进行设计。

　　　第三章 对掩护式液压支架中立柱及其他千斤顶的设计。

　　　根据液压支架的工作要求、环境，完成对支架立柱液压缸及其他千斤顶的设计。

　　　第四章 对掩护式液压支架的液压系统的设计与计算。

　　　根据支架需要完成的动作，确定液压系统的回路，从而拟定液压系统原理图，并完成液压系统的验算。

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.
