【正文】 ……… 焦化廠推焦機(jī)的設(shè)計(jì) 摘 要 煉焦工業(yè)是一個(gè)國(guó)家基礎(chǔ)工業(yè)，其中推焦機(jī)是煉焦車間最重要的機(jī)械。它的任務(wù)是進(jìn)行推焦、平煤、在推焦前后摘下與安上機(jī)側(cè)爐門、推焦時(shí)用壓縮空氣吹掃炭化室頂部的石墨。 行走機(jī)構(gòu)和推焦裝置是推焦機(jī)上最重要的兩個(gè)機(jī)構(gòu)，本次畢業(yè)設(shè)計(jì)主要內(nèi)容就是行走機(jī)構(gòu)和推焦裝置設(shè)計(jì)。推焦裝置主要由電機(jī)、減速器、齒輪齒條傳動(dòng)裝置等部件組成。根據(jù)原有數(shù)據(jù)和參考資料，結(jié)合所學(xué)的專業(yè)知識(shí)，詳細(xì)設(shè)計(jì)了推焦機(jī)行走機(jī)構(gòu)和推焦裝置 。 關(guān)鍵詞 ： 推焦機(jī) 行走機(jī)構(gòu) 推焦裝置 焦?fàn)t 焦炭 安徽工業(yè)大學(xué) 畢業(yè)設(shè)計(jì)（論文）說(shuō)明書 II …………………………………………………………………裝…………………訂……………………線………………………………………………………… Abstract Walking mechanism and coke pushing device is the most two important institutions of the coke main content of this graduation design is the walking mechanism and coke pushing device mechanism is mainly posed of wheel and rail, motor, reducer, brake parts, etc. Coke pushing device is mainly posed of motor,reducer,gear rack transmission device parts,etc. Coke pusher is the most important machinery in the coking task is to pushing coke , leveling coke , before and after the pushing time remove and install the pusher side oven door , using pressed air to sweep graphite at the top of coking chamber when it is pushing . Modern pusher machine mainly made up by Steel Timber , Walking mechanism, Pusher mechanism, Leveling mechanism, Opening mechanism , air pressor and so on . The weight of the whole pusher machine is 120130 tons This paper introduced the coke pusher’s walking mechanism and structure of coke pushing device , working principle in detail . According to the original data and resources and bined with learned professional knowledge , Detailed design the pusher machine’s walking mechanism and coke pushing device . And use Auto CAD to draw a plete assembly drawing and parts drawing . After calculation and strength check it can meet the practical requirements Key words : Coke pusher、 Walking mechanism、 Pusher device、 Coke oven、 Coke 安徽工業(yè)大學(xué) 畢業(yè)設(shè)計(jì)（論文）說(shuō)明書 …………………………………………………………………裝…………………訂……………………線………………………………………………………… IV 目 錄 摘 要 ........................................................................................................................................
