1、摘要近年來,帶式輸送機(jī)在礦山運(yùn)輸中已經(jīng)逐漸開始取代汽車和機(jī)車運(yùn)輸,成為散裝物料的主要運(yùn)輸裝備。不斷出現(xiàn)新型帶式輸送機(jī),拓寬了帶式輸送機(jī)的應(yīng)用領(lǐng)域。可伸縮帶式輸送機(jī)是連續(xù)輸送物料機(jī)械中效率最高、使用最普遍的一種機(jī)型,是巷道掘進(jìn)運(yùn)輸和采煤工作面順槽運(yùn)輸?shù)闹饕O(shè)備。在煤炭、冶金領(lǐng)域中,可伸縮帶式輸送機(jī)得到了廣泛應(yīng)用。為適應(yīng)這一變化,本文主要針對(duì)帶式輸送機(jī)中的可伸縮帶式輸送機(jī)進(jìn)行了結(jié)構(gòu)設(shè)計(jì),包括可伸縮帶式輸送機(jī)輸送帶的選擇、中間架的選擇計(jì)算、傳動(dòng)裝置的設(shè)計(jì)、張緊裝置、收放膠帶裝置的計(jì)算、托輥以及滾筒的選擇計(jì)算等,并針對(duì)其結(jié)構(gòu)及其工作原理作了概括性總結(jié)??缮炜s帶
