摘 要
本文闡述了掩護(hù)式液壓支架的設(shè)計(jì)過(guò)程，包括液壓支架的整體設(shè)計(jì)，結(jié)構(gòu)設(shè)計(jì)，強(qiáng)度校核等。文中采用VB程序?qū)λ倪B桿進(jìn)行優(yōu)化設(shè)計(jì)計(jì)算，避免了傳統(tǒng)復(fù)雜費(fèi)時(shí)的試算法，同時(shí)又能有效的地控制頂梁前端點(diǎn)運(yùn)動(dòng)的雙紐線軌跡的寬度在30mm以內(nèi)，更好的達(dá)到液壓支架的設(shè)計(jì)要求。液壓支架的設(shè)計(jì)、制造和使用，從1954年英國(guó)研制成功了液壓支架發(fā)展到現(xiàn)在，已經(jīng)基本成熟，它已經(jīng)形成了能適應(yīng)各種不同煤礦地質(zhì)條件的各類(lèi)液壓支架。支架的部件設(shè)計(jì)包括立柱，推移千斤頂 ，底座等部件的設(shè)計(jì)。本設(shè)計(jì)中采用單伸縮雙作用式立柱，底座采用整體箱式結(jié)構(gòu)。千斤頂采用浮動(dòng)推移千斤頂，以減少推溜力，增大移架力。

Abstract
In this paper, cover-hydraulic support the design process, including hydraulic support the overall design, structural design, strength, such as checking. VB procedures used in the text of the four-link optimized design, to avoid the traditional complex and time-consuming test method, while effective control of the top beam front of the two-point movement trajectory of the New Zealand line in the width of 30 mm within the reach of better Pressure stent design requirements. Hydraulic support for the design, manufacture and use, from 1954 the British successfully developed a hydraulic support the development up to now, has basically matured, it has become to adapt to the different geological conditions of coal mines of various types of hydraulic support. Stent design, including parts of the column, Jack goes, the design of the base and other components. The design of single-column stretching double role, please use the box-type structure. Jack Jack with floating over to reduce the push slip, and increased power-shift.
Key words: Hydraulic Support ；four-bar mechanism；Optimal Design ；standing-column；baseplate
