電(dian)(dian)(dian)梯(ti)是(shi)一種以電(dian)(dian)(dian)動(dong)機(ji)(ji)為動(dong)力(li)的(de)垂(chui)(chui)直(zhi)(zhi)升降(jiang)機(ji)(ji)，裝(zhuang)有(you)箱狀吊(diao)艙，用(yong)于(yu)多層建(jian)筑(zhu)乘(cheng)人(ren)或載運(yun)貨物(wu)(wu)。也(ye)有(you)臺(tai)階式(shi)，踏步板裝(zhuang)在履帶上連續運(yun)行，俗稱自動(dong)扶梯(ti)或自動(dong)人(ren)行道。服務于(yu)規定樓(lou)層的(de)固(gu)定式(shi)升降(jiang)設備。垂(chui)(chui)直(zhi)(zhi)升降(jiang)電(dian)(dian)(dian)梯(ti)具(ju)有(you)一個(ge)轎廂，運(yun)行在至少兩(liang)列垂(chui)(chui)直(zhi)(zhi)的(de)或傾斜角小(xiao)于(yu)15°的(de)剛性(xing)導(dao)軌之間(jian)。轎廂尺寸與結構(gou)形(xing)式(shi)便于(yu)乘(cheng)客出入或裝(zhuang)卸(xie)貨物(wu)(wu)。習慣(guan)上不(bu)論其(qi)驅動(dong)方式(shi)如(ru)何，防爆電(dian)(dian)(dian)梯(ti)哪家好，將電(dian)(dian)(dian)梯(ti)作為建(jian)筑(zhu)物(wu)(wu)內垂(chui)(chui)直(zhi)(zhi)交通運(yun)輸工具(ju)的(de)總稱。按(an)速(su)度可(ke)分低速(su)電(dian)(dian)(dian)梯(ti)(1米(mi)/秒(miao)以下)、快(kuai)速(su)電(dian)(dian)(dian)梯(ti)(1~2米(mi)/秒(miao))和高速(su)電(dian)(dian)(dian)梯(ti)(2米(mi)/秒(miao)以上)。19世(shi)紀中期開始出現液壓電(dian)(dian)(dian)梯(ti)，至今仍(reng)在低層建(jian)筑(zhu)物(wu)(wu)上應用(yong)。1852年，美國的(de)E.G.奧蒂斯研制出鋼絲繩提升的(de)安(an)全升降(jiang)機(ji)(ji)。80年代，驅動(dong)裝(zhuang)置有(you)進一步改進，如(ru)電(dian)(dian)(dian)動(dong)機(ji)(ji)通過蝸(gua)桿傳(chuan)動(dong)帶動(dong)纏繞(rao)卷筒、采用(yong)平衡重(zhong)等。19世(shi)紀末，采用(yong)了摩擦輪傳(chuan)動(dong)，大(da)大(da)增加電(dian)(dian)(dian)梯(ti)的(de)提升高度。

電梯停電

一般(ban)(ban)的(de)電(dian)(dian)(dian)梯(ti)(ti)(ti)，轎廂上面(mian)都有(you)(you)好多(duo)條安(an)(an)全繩，安(an)(an)全系數很高。所以(yi)，電(dian)(dian)(dian)梯(ti)(ti)(ti)一般(ban)(ban)是(shi)不會(hui)(hui)掉(diao)下(xia)電(dian)(dian)(dian)梯(ti)(ti)(ti)槽(cao)的(de)。電(dian)(dian)(dian)梯(ti)(ti)(ti)都裝有(you)(you)防(fang)墜安(an)(an)全裝置(zhi)，什(shen)么是(shi)防(fang)爆(bao)電(dian)(dian)(dian)梯(ti)(ti)(ti)，即(ji)使(shi)停電(dian)(dian)(dian)了，電(dian)(dian)(dian)燈熄滅了，安(an)(an)全裝置(zhi)也不會(hui)(hui)失(shi)靈。電(dian)(dian)(dian)梯(ti)(ti)(ti)會(hui)(hui)牢(lao)牢(lao)夾住電(dian)(dian)(dian)梯(ti)(ti)(ti)槽(cao)兩帝的(de)鋼軌，使(shi)電(dian)(dian)(dian)梯(ti)(ti)(ti)不至于掉(diao)下(xia)去。電(dian)(dian)(dian)梯(ti)(ti)(ti)里面(mian)一般(ban)(ban)都有(you)(you)指(zhi)示(shi)，告(gao)訴你出現這(zhe)種情(qing)況，防(fang)爆(bao)電(dian)(dian)(dian)梯(ti)(ti)(ti)廠，應(ying)(ying)該(gai)怎(zen)么處理。大多(duo)數電(dian)(dian)(dian)梯(ti)(ti)(ti)，都有(you)(you)應(ying)(ying)急鈴，你應(ying)(ying)該(gai)首先摁下(xia)這(zhe)個，告(gao)訴周圍的(de)人，有(you)(you)人被困電(dian)(dian)(dian)梯(ti)(ti)(ti)里面(mian)了。如果電(dian)(dian)(dian)梯(ti)(ti)(ti)里面(mian)有(you)(you)信(xin)號，可以(yi)撥(bo)打電(dian)(dian)(dian)話(hua)，應(ying)(ying)該(gai)首先按照電(dian)(dian)(dian)梯(ti)(ti)(ti)里面(mian)的(de)指(zhi)示(shi)，撥(bo)打電(dian)(dian)(dian)梯(ti)(ti)(ti)故障求助電(dian)(dian)(dian)話(hua)。如果求助電(dian)(dian)(dian)話(hua)沒有(you)(you)人值班，那就打電(dian)(dian)(dian)話(hua)報(bao)警。告(gao)訴對(dui)方自(zi)己(ji)所在(zai)的(de)位置(zhi)。
