機架與系統結構

帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)(ji)機(ji)(ji)架(jia)是帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)(ji)的(de)(de)骨架(jia)，主要包括機(ji)(ji)頭站、機(ji)(ji)尾站和(he)中間架(jia)三大部分中小型輸(shu)送(song)(song)機(ji)(ji)的(de)(de)驅動裝置(zhi)(zhi)經常布置(zhi)(zhi)在(zai)機(ji)(ji)頭和(he)機(ji)(ji)尾；大型帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)(ji)的(de)(de)驅動站，根據系(xi)統(tong)設(she)(she)計(ji)可以布置(zhi)(zhi)在(zai)輸(shu)送(song)(song)機(ji)(ji)系(xi)統(tong)的(de)(de)任何位置(zhi)(zhi)上。帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)(ji)系(xi)統(tong)中還(huan)會(hui)涉(she)及(ji)物料的(de)(de)轉載、分流與(yu)匯集(ji)等設(she)(she)施與(yu)裝置(zhi)(zhi)。一些帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)(ji)系(xi)統(tong)還(huan)需(xu)要設(she)(she)置(zhi)(zhi)棧橋(qiao)和(he)地道以適應各(ge)種不(bu)同的(de)(de)工程(cheng)設(she)(she)計(ji)需(xu)求。本(ben)章(zhang)介(jie)紹(shao)這些設(she)(she)備(結(jie)構)或設施的工程設計與應用。

(1)機(ji)架(jia)的(de)類型。帶(dai)式(shi)(shi)(shi)輸送(song)(song)機(ji)機(ji)架(jia)類型與帶(dai)式(shi)(shi)(shi)輸送(song)(song)機(ji)的(de)類型有關。通用帶(dai)式(shi)(shi)(shi)輸送(song)(song)機(ji)分為(wei)固定式(shi)(shi)(shi)、半移(yi)(yi)動(dong)式(shi)(shi)(shi)、移(yi)(yi)置式(shi)(shi)(shi)帶(dai)式(shi)(shi)(shi)輸送(song)(song)機(ji)，其機(ji)架(jia)類型相應(ying)為(wei)固定式(shi)(shi)(shi)、可(ke)移(yi)(yi)動(dong)式(shi)(shi)(shi)

固定(ding)(ding)式(shi)帶(dai)式(shi)輸(shu)(shu)送機應用于工作地點固定(ding)(ding)不變，或服務(wu)年限較長的(de)場所。例如工廠、碼頭，電廠、選煤廠、干線輸(shu)(shu)送系統(tong)等(deng)。這類帶(dai)式(shi)輸(shu)(shu)送機機頭站、機尾(wei)站和(he)中間架為固定(ding)(ding)式(shi)結構。

半移(yi)動式(shi)(shi)帶式(shi)(shi)輸(shu)送(song)機(ji)(ji)(ji)(ji)應用(yong)(yong)(yong)于工(gong)作(zuo)地(di)點(dian)需定期變換、在一個地(di)點(dian)服務年限短或(huo)工(gong)程地(di)質(zhi)條件較(jiao)差需經(jing)常(chang)維修等場所，如露天礦山的(de)端(duan)幫及坑內干線帶式(shi)(shi)輸(shu)送(song)機(ji)(ji)(ji)(ji)。機(ji)(ji)(ji)(ji)頭站(zhan)和機(ji)(ji)(ji)(ji)尾站(zhan)需采用(yong)(yong)(yong)可(ke)(ke)移(yi)動式(shi)(shi)，可(ke)(ke)通(tong)過牽(qian)引(yin)設備或(huo)馱運設備整體(ti)拖牽(qian)或(huo)馱運。由于移(yi)設工(gong)作(zuo)的(de)需要，機(ji)(ji)(ji)(ji)頭站(zhan)的(de)滾(gun)筒、驅動等裝(zhuang)置與鋼(gang)(gang)結(jie)構形(xing)成整體(ti)式(shi)(shi)結(jie)構，國(guo)外稱(cheng)之(zhi)為可(ke)(ke)移(yi)動式(shi)(shi)機(ji)(ji)(ji)(ji)頭站(zhan)和機(ji)(ji)(ji)(ji)尾站(zhan)。中間架采用(yong)(yong)(yong)軌枕或(huo)鋼(gang)(gang)筋混凝土(tu)枕支(zhi)撐，為單元可(ke)(ke)移(yi)動式(shi)(shi)整體(ti)結(jie)構，中間架單元之(zhi)間無機(ji)(ji)(ji)(ji)械連(lian)接(jie)

移(yi)置(zhi)式(shi)帶式(shi)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)應用于(yu)需(xu)經常橫向移(yi)設(she)的(de)工(gong)作場所。如(ru)露(lu)天礦山的(de)采據工(gong)作面(mian)和排上工(gong)作面(mian)的(de)帶式(shi)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)。機(ji)(ji)頭結和機(ji)(ji)尾站為可移(yi)動(dong)(dong)式(shi)，可通過牽引或(huo)(huo)馱運設(she)備(bei)整(zheng)體(ti)拖牽或(huo)(huo)馱運。中(zhong)間(jian)(jian)架(jia)(jia)為單元(yuan)整(zheng)體(ti)結構，帶有(you)單軌或(huo)(huo)雙(shuang)軌的(de)鋼(gang)(gang)枕支撐(cheng)，中(zhong)間(jian)(jian)架(jia)(jia)單元(yuan)之間(jian)(jian)無機(ji)(ji)械連(lian)接。與半(ban)移(yi)動(dong)(dong)式(shi)帶式(shi)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)中(zhong)間(jian)(jian)架(jia)(jia)的(de)區別(bie)在于(yu)移(yi)置(zhi)式(shi)帶式(shi)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)的(de)中(zhong)間(jian)(jian)架(jia)(jia)鋼(gang)(gang)枕上有(you)單條(tiao)或(huo)(huo)兩條(tiao)鋼(gang)(gang)軌，并且中(zhong)例架(jia)(jia)結構需(xu)滿足輸(shu)(shu)送(song)(song)(song)機(ji)(ji)橫向移(yi)設(she)的(de)受力要求(qiu)。
