The hoisting machinery and the transport machinery develops to the present, have already became the reasonable organization in groups mass productions and the mechanization streamlined production foundation, it is the one of modernized production important symbols. In our country four modernizations development and each industry sector mechanization level, in labor productivitys enhancement, the hoist crane will certainly to play the major role. This design of hoist crane is the 50/10t double beam bridge type hoist crane, mainly uses in various workshops, the partition production line and the steel products dump site and so on place. The bridge-type hoist crane itself makes the derailing, on frames winch makes the longitudinal shift, hangs makes the vertical migration on winchs lift hook, three directions movements synthesis can cause the hoist crane to have an effect. In order to prevent the bridge-type hoist crane to look at not the clear concrete lift hook mode of motion in the pilot, as soon as in the ground is a match has the heavy industry to carry on the direction or to clamp, puts the lift hook.This topic mainly carries on the system design to the 50/10t double beam bridge type hoist cranes host hoisting mechanism, designed in the process to consult the massive domestic and foreign correlation data, did the design has utilized the massive special courses. First through the definite transmission plan, the choice block and tackle and the lift hook group, chooses the appropriate steel wire, calculates pulleys main dimension, the definite reel size and checking calculation its intensity, the computation floats the moving axis high speed, chooses the appropriate electric motor, the reduction gear, the brake and the shaft coupling. The request hoisting equipment movement is steady, the localization is accurate, safe reliable, the technical performance is stable.Key words crane bridge crane lifting mechanism designII徐州工程學(xué)院畢業(yè)設(shè)計(jì)(論文)目 錄1緒論11.1起重機(jī)概述11.2起重機(jī)的分類11.3起升機(jī)構(gòu)介紹22起重機(jī)的國(guó)內(nèi)外發(fā)展?fàn)顩r42.1起重機(jī)的國(guó)外發(fā)展?fàn)顩r42.2起重機(jī)的國(guó)內(nèi)發(fā)展?fàn)顩r63橋式起重機(jī)的主要技術(shù)參數(shù)與工作級(jí)別83.1橋式起重機(jī)的主要技術(shù)參數(shù)83.2橋式起重機(jī)的工作級(jí)別104傳動(dòng)方案的選擇114.1驅(qū)動(dòng)裝置的布置方式114.1.1電動(dòng)起升機(jī)構(gòu)114.1.2液壓起升機(jī)構(gòu)115鋼絲繩的選擇135.1鋼絲繩的特性135.2鋼絲繩的種類135.2.1根據(jù)鋼絲繩的捻繞次數(shù)分類135.2.2按鋼絲繩的捻向分類135.2.3根據(jù)股的形狀分類145.2.4根據(jù)股的構(gòu)造分類145.2.5根據(jù)鋼絲表面處理分類155.2.6根據(jù)鋼絲繩股數(shù)的數(shù)目分類155.2.7根據(jù)繩芯分類155.3鋼絲繩的選擇156滑輪、卷筒的計(jì)算176.1卷筒的構(gòu)造與類型176.1.1按鋼絲繩在卷筒上的卷繞層數(shù)分類176.1.2按卷筒的表面不同分類176.1.3.按卷筒的制作方法分類186.2卷筒、滑輪的設(shè)計(jì)計(jì)算186.2.1滑輪、卷筒最小直徑的確定186.2.2卷筒長(zhǎng)度和厚度的計(jì)算186.2.3卷筒轉(zhuǎn)速196.2.4卷筒壓應(yīng)力驗(yàn)算206.2.5卷筒強(qiáng)度驗(yàn)算206.3鋼絲繩在卷筒上的固定方法217初選電動(dòng)機(jī)和減速器的選擇227.1初選電動(dòng)機(jī)227.2減速器的選擇228制動(dòng)器的選擇248.1概述248.2制動(dòng)裝置的分類248.2.1按制動(dòng)器的結(jié)構(gòu)形式分類248.2.2按制動(dòng)器工作狀態(tài)分類258.2.3按制動(dòng)器的驅(qū)動(dòng)方式分類258.3塊式制動(dòng)器258.4塊式制動(dòng)器的設(shè)計(jì)278.5起動(dòng)時(shí)間與起動(dòng)加速度的驗(yàn)算298.6電動(dòng)機(jī)起動(dòng)可靠性的驗(yàn)算299.聯(lián)軸器的選擇和高速浮動(dòng)軸驗(yàn)算319.1聯(lián)軸器選擇319.2高速浮動(dòng)軸的驗(yàn)算32結(jié)論33致謝34參考文獻(xiàn)35附錄36附錄1362
