扶手電梯組成結構

扶(fu)手(shou)電梯(ti)(ti)由梯(ti)(ti)路(lu)（變型的板式輸(shu)送(song)機(ji)）和兩(liang)旁的扶(fu)手(shou)（變形(xing)的帶式輸(shu)送(song)機(ji)）組成(cheng)。其主(zhu)要部件有梯(ti)(ti)級(ji)(ji)、牽引鏈(lian)條及(ji)鏈(lian)輪(lun)、導(dao)軌系統、主(zhu)傳動(dong)系統（包括電動(dong)機(ji)、減(jian)速(su)裝(zhuang)置、制(zhi)動(dong)器(qi)及(ji)中(zhong)間傳動(dong)環節等(deng)）驅(qu)動(dong)主(zhu)軸(zhou)、梯(ti)(ti)路(lu)張緊(jin)裝(zhuang)置、扶(fu)手(shou)系統、梳(shu)板、扶(fu)梯(ti)(ti)骨(gu)架和電氣系統等(deng)。梯(ti)(ti)級(ji)(ji)在乘(cheng)客入(ru)(ru)口處作水(shui)平(ping)運動(dong)（方(fang)便乘(cheng)客登梯(ti)(ti)）以后逐(zhu)漸形(xing)成(cheng)階(jie)梯(ti)(ti)；接近入(ru)(ru)口處階(jie)梯(ti)(ti)逐(zhu)漸消失(shi)，梯(ti)(ti)級(ji)(ji)再(zai)度作水(shui)平(ping)運動(dong)。這些運動(dong)都是由梯(ti)(ti)級(ji)(ji)主(zhu)輪(lun)、輔輪(lun)分(fen)別(bie)沿不同的梯(ti)(ti)級(ji)(ji)導(dao)軌行走來實現的。

所有可能產(chan)生危險火花或危險溫度的部件(jian)或部位(wei)都必(bi)須采(cai)取相應的防爆安全(quan)措施。

(1)電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji) 曳引電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)采用(yong)交流(liu)雙速(su)單繞(rao)組或(huo)特(te)i制(zhi)的(de)(de)交流(liu)雙速(su)雙繞(rao)組電(dian)(dian)(dian)梯用(yong)隔爆型三相異(yi)步電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)。該電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)在繞(rao)組中和軸(zhou)承兩端埋有(you)溫(wen)度感(gan)應(ying)元件以(yi)防止可能的(de)(de)過載，并且(qie)電(dian)(dian)(dian)機(ji)(ji)應(ying)能適應(ying)電(dian)(dian)(dian)梯頻繁啟動(dong)(dong)(dong)、制(zhi)動(dong)(dong)(dong)、快速(su)控(kong)制(zhi)和慢速(su)控(kong)制(zhi)等(deng)工作要求，具有(you)啟動(dong)(dong)(dong)轉矩(ju)大(da)、全負荷啟動(dong)(dong)(dong)時啟動(dong)(dong)(dong)電(dian)(dian)(dian)流(liu)小等(deng)特(te)點。電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)及其溫(wen)度控(kong)制(zhi)電(dian)(dian)(dian)路的(de)(de)防爆標志應(ying)不低于dⅡBT4或(huo)d(ib)ⅡBT4等(deng)級。

(2)交流(liu)閘瓦式制(zhi)(zhi)動器(qi) 交流(liu)閘瓦式制(zhi)(zhi)動器(qi)位(wei)于電(dian)動機和減速器(qi)之間，防爆電(dian)梯廠，其上配(pei)有隔(ge)(ge)爆電(dian)磁鐵。制(zhi)(zhi)動器(qi)的制(zhi)(zhi)動輪是(shi)聯軸節的一(yi)部分，制(zhi)(zhi)動器(qi)靠(kao)兩側的彈簧(huang)施閘，防爆電(dian)梯哪家好，靠(kao)交流(liu)隔(ge)(ge)爆電(dian)磁鐵開閘。隔(ge)(ge)爆電(dian)磁鐵的防爆標(biao)志應(ying)不低于dⅡBT4等級。

乘坐(zuo)電梯時應注(zhu)意(yi)哪(na)些事項(xiang)？

答(da)：當(dang)你進(jin)、出入轎廂(xiang)時，要看一下(xia)電(dian)(dian)(dian)梯是否在(zai)平層位置，什么是防爆電(dian)(dian)(dian)梯，特別是在(zai)夜間光線不清的時候，舟山(shan)防爆電(dian)(dian)(dian)梯，更應注意，否則有(you)可(ke)能(neng)造成傷害；電(dian)(dian)(dian)梯是公共場合，不應攜(xie)帶易(yi)i燃易(yi)i爆或具有(you)腐蝕(shi)性的物(wu)品；電(dian)(dian)(dian)梯運(yun)行期間，不要擠(ji)靠或拍打電(dian)(dian)(dian)梯門，以免造成電(dian)(dian)(dian)梯誤動作(zuo)而(er)停梯。 ? ?電(dian)(dian)(dian)梯運(yun)行不正常時，在(zai)轎廂(xiang)內怎么辦？

答(da)：當你乘電(dian)梯，發(fa)現電(dian)梯有超i速(su)或(huo)梯速(su)較慢，轎(jiao)廂內有異(yi)常(chang)的焦煳(hu)味(wei)、有異(yi)常(chang)震動或(huo)晃動，刮蹭現象、有異(yi)常(chang)的聲響時，應(ying)按(an)(an)下(xia)操縱(zong)盤上的紅色急停按(an)(an)鈕，電(dian)梯會自動停車(che)；然后及(ji)時通報電(dian)梯維(wei)修(xiu)人(ren)員，并(bing)等待維(wei)修(xiu)人(ren)員開門放(fang)人(ren)。
