摘 要 本次畢業(yè)設(shè)計(jì)是關(guān)于液壓升降舞臺(tái)的設(shè)計(jì)。首先對(duì)液壓升降舞臺(tái)作了簡(jiǎn)單的概述；接著分析了液壓升降舞臺(tái)的選型原則及計(jì)算方法；然后根據(jù)這些設(shè)計(jì)準(zhǔn)則與計(jì)算選型方法按照給定參數(shù)要求進(jìn)行選型設(shè)計(jì)；接著對(duì)所選擇的液壓升降舞臺(tái)各主要零部件進(jìn)行了校核。最后簡(jiǎn)單的說(shuō)明了液壓升降舞臺(tái)的安裝與維護(hù)。目前，液壓升降舞臺(tái)正朝著長(zhǎng)距離，高速度，低摩擦的方向發(fā)展，近年來(lái)出現(xiàn)的液壓升降舞臺(tái)就是其中的一個(gè)。在液壓升降舞臺(tái)的設(shè)計(jì)、制造以及應(yīng)用方面,目前我國(guó)與國(guó)外先進(jìn)水平相比仍有較大差距,國(guó)內(nèi)在設(shè)計(jì)制造液壓升降舞臺(tái)過(guò)程中存在著很多不足。 Abstract The design is a graduation project about the hydraulic pressure lift proscenium. At first, it is introduction about hydraulic pressure lift proscenium. Next, it is the principles about choose component parts of hydraulic pressure lift proscenium. After that t hydraulic pressure lift proscenium abase on the principle is designed. Then, it is checking computations about main component parts of hydraulic pressure lift proscenium. At last, it is explanation about fix and safeguard of hydraulic pressure lift proscenium. Today, long distance, high speed, low friction is the direction of hydraulic pressure lift proscenium’s development. Hydraulic pressure lift proscenium is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of hydraulic pressure lift proscenium。
