摘 要
懸臂式掘進(jìn)機(jī)是井下巷道掘進(jìn)和開(kāi)拓的主要設(shè)備,掘進(jìn)機(jī)截割部主要由截割臂的擺動(dòng)和截割頭轉(zhuǎn)動(dòng)來(lái)進(jìn)行截割煤層和巖石。設(shè)計(jì)該截割部采用縱軸式截割機(jī)構(gòu)。該設(shè)計(jì)使懸臂式掘進(jìn)機(jī)具有掘進(jìn)速度快,巷道成形好,工作穩(wěn)定可靠,工作操作簡(jiǎn)單方便。
掘進(jìn)機(jī)截割機(jī)構(gòu)是掘進(jìn)機(jī)的主要組成部分,掘進(jìn)機(jī)截割部由截割臂、二級(jí)行星減速器、電動(dòng)機(jī)以及液壓油缸幾部分組成。在設(shè)計(jì)時(shí),電動(dòng)機(jī)用比能耗法來(lái)計(jì)算從而進(jìn)行選型,截割臂和二級(jí)行星減速用傳動(dòng)關(guān)系來(lái)進(jìn)行設(shè)計(jì)計(jì)算和校核,液壓油缸通過(guò)材料強(qiáng)度和力計(jì)算進(jìn)行校核。
