太原家用電梯公司合興永達今天為大家帶來如何保障電梯乘客安全，一起看看吧！

電(dian)梯(ti)是(shi)在(zai)垂直方向上的交(jiao)通工具。盡管(guan)在(zai)此(ci)之(zhi)前升降裝(zhuang)置已(yi)(yi)經使用(yong)了(le)(le)多(duo)年(nian)(nian)，但電(dian)梯(ti)界(jie)都認為電(dian)梯(ti)是(shi)美(mei)國的otis先(xian)生(sheng)于1853年(nian)(nian)發明的。這是(shi)因為是(shi)otis先(xian)生(sheng)首先(xian)給鋼絲繩懸掛(gua)的升降機加裝(zhuang)了(le)(le)一個安(an)全(quan)裝(zhuang)置，使其變成了(le)(le)電(dian)梯(ti)。所(suo)以，電(dian)梯(ti)自(zi)發明之(zhi)日起(qi)就已(yi)(yi)打上了(le)(le)安(an)全(quan)標(biao)記(ji)。今天的電(dian)梯(ti)其安(an)全(quan)性與150年(nian)(nian)前已(yi)(yi)經無法相(xiang)比(bi)了(le)(le)，據有關資料(liao)介紹：乘坐電(dian)梯(ti)比(bi)爬樓(lou)梯(ti)安(an)全(quan)10倍。不僅如此(ci)，與汽車、火車等交(jiao)通工具相(xiang)比(bi)，電(dian)梯(ti)也是(shi)安(an)全(quan)的。

像交通工具(ju)一(yi)(yi)樣(yang)，電(dian)梯在給人們(men)節省(sheng)體力和時間的同時，也不可避免地帶來(lai)了(le)一(yi)(yi)定的風(feng)(feng)險。為了(le)把這(zhe)種(zhong)風(feng)(feng)險降到低程度(du)，多年來(lai)人們(men)一(yi)(yi)直(zhi)都(dou)在對電(dian)梯進(jin)行(xing)改進(jin)，使(shi)得(de)它的安全保障措施日趨(qu)完善(shan)。乘坐電(dian)梯到底有什么風(feng)(feng)險呢？ 

乘客在進入(ru)或(huo)走出電(dian)梯(ti)時要通過層(ceng)門，此(ci)時可能(neng)(neng)會(hui)造(zao)成(cheng)傷(shang)(shang)害的是(shi)跌入(ru)井道或(huo)被剪切(qie)；乘客在乘坐(zuo)電(dian)梯(ti)的過程中，可能(neng)(neng)會(hui)造(zao)成(cheng)傷(shang)(shang)害的是(shi)由非(fei)正常的加（減）速度造(zao)成(cheng)的失重(zhong)(zhong)、超重(zhong)(zhong)和(he)沖擊(ji)。這些危險事件發生的概率(lv)雖(sui)然不高(gao)，但后果為嚴重(zhong)(zhong)，是(shi)必(bi)須排除的大安全風險。

電梯(ti)如(ru)何消除這些風險呢？

在乘坐電(dian)梯(ti)的(de)(de)過(guo)(guo)程中，與乘客(ke)(ke)有關(guan)的(de)(de)空(kong)(kong)(kong)間(jian)(jian)有三個：一個是樓層(ceng)——在不同高度上(shang)的(de)(de)水平空(kong)(kong)(kong)間(jian)(jian)；一個是井(jing)道(dao)(dao)——連接(jie)各個樓層(ceng)的(de)(de)豎(shu)直空(kong)(kong)(kong)間(jian)(jian)；另一個是電(dian)梯(ti)轎廂(xiang)——通過(guo)(guo)在井(jing)道(dao)(dao)內的(de)(de)上(shang)下移動(dong)而把乘客(ke)(ke)運送到不同樓層(ceng)的(de)(de)封閉空(kong)(kong)(kong)間(jian)(jian)。樓層(ceng)和轎廂(xiang)是安全空(kong)(kong)(kong)間(jian)(jian)，井(jing)道(dao)(dao)是危險空(kong)(kong)(kong)間(jian)(jian)。顯(xian)然，電(dian)梯(ti)必須提供這樣(yang)的(de)(de)保證：乘客(ke)(ke)只能在樓層(ceng)上(shang)或(huo)者在轎廂(xiang)里(li)，而不可能進入井(jing)道(dao)(dao)里(li)；如果(guo)乘客(ke)(ke)身體的(de)(de)一部(bu)分在樓層(ceng)里(li)一部(bu)分在轎廂(xiang)里(li)，此時轎廂(xiang)不可運動(dong)。——這就是電(dian)梯(ti)對乘客(ke)(ke)的(de)(de)空(kong)(kong)(kong)間(jian)(jian)限(xian)制。

電(dian)(dian)(dian)梯(ti)(ti)停(ting)(ting)層時速(su)(su)度(du)(du)為(wei)零(ling)，正常運行時以額定(ding)速(su)(su)度(du)(du)做(zuo)勻(yun)速(su)(su)直線運動(dong)。在(zai)(zai)(zai)零(ling)速(su)(su)與額定(ding)速(su)(su)度(du)(du)之間的(de)(de)(de)(de)(de)過(guo)渡階段則做(zuo)勻(yun)加(jia)速(su)(su)或勻(yun)減(jian)速(su)(su)運動(dong)，此(ci)(ci)時乘客(ke)(ke)會承受一定(ding)的(de)(de)(de)(de)(de)超重(zhong)(zhong)(zhong)與失重(zhong)(zhong)(zhong)，在(zai)(zai)(zai)正常情況(kuang)(kuang)下可能會有輕(qing)微的(de)(de)(de)(de)(de)不(bu)適(shi)但不(bu)會造成傷害(hai)。在(zai)(zai)(zai)電(dian)(dian)(dian)梯(ti)(ti)運行出現意外的(de)(de)(de)(de)(de)情況(kuang)(kuang)下，如果轎(jiao)廂運行速(su)(su)度(du)(du)超過(guo)規定(ding)的(de)(de)(de)(de)(de)數值(zhi)、轎(jiao)廂在(zai)(zai)(zai)端站未停(ting)(ting)靠而駛向井道底(di)坑或頂板、正在(zai)(zai)(zai)運行的(de)(de)(de)(de)(de)電(dian)(dian)(dian)梯(ti)(ti)突(tu)然中(zhong)(zhong)斷供(gong)電(dian)(dian)(dian)等，此(ci)(ci)時電(dian)(dian)(dian)梯(ti)(ti)配備的(de)(de)(de)(de)(de)安(an)(an)全(quan)部(bu)件(jian)將會起作用使電(dian)(dian)(dian)梯(ti)(ti)停(ting)(ting)止運行。在(zai)(zai)(zai)安(an)(an)全(quan)部(bu)件(jian)動(dong)作過(guo)程(cheng)(cheng)中(zhong)(zhong)，為(wei)了保證(zheng)(zheng)乘客(ke)(ke)安(an)(an)全(quan)，電(dian)(dian)(dian)梯(ti)(ti)提供(gong)了這(zhe)樣的(de)(de)(de)(de)(de)保證(zheng)(zheng)：轎(jiao)廂的(de)(de)(de)(de)(de)制(zhi)停(ting)(ting)減(jian)速(su)(su)度(du)(du)不(bu)超過(guo)重(zhong)(zhong)(zhong)力加(jia)速(su)(su)度(du)(du)gn。乘客(ke)(ke)承受其值(zhi)為(wei)gn的(de)(de)(de)(de)(de)制(zhi)停(ting)(ting)減(jian)速(su)(su)度(du)(du)意味著腳底(di)板承受了2倍的(de)(de)(de)(de)(de)體重(zhong)(zhong)(zhong)，持續(xu)的(de)(de)(de)(de)(de)時間一般不(bu)會超過(guo)1s，所(suo)以gn是(shi)(shi)國際公(gong)認(ren)的(de)(de)(de)(de)(de)安(an)(an)全(quan)制(zhi)停(ting)(ting)減(jian)速(su)(su)度(du)(du)。——這(zhe)就(jiu)是(shi)(shi)電(dian)(dian)(dian)梯(ti)(ti)對乘客(ke)(ke)的(de)(de)(de)(de)(de)加(jia)（減(jian)）速(su)(su)度(du)(du)限制(zhi)。  就(jiu)這(zhe)樣，電(dian)(dian)(dian)梯(ti)(ti)給乘客(ke)(ke)創造了一個安(an)(an)全(quan)的(de)(de)(de)(de)(de)空間和一個安(an)(an)全(quan)的(de)(de)(de)(de)(de)加(jia)（減(jian)）速(su)(su)度(du)(du)，從而保證(zheng)(zheng)了乘坐(zuo)電(dian)(dian)(dian)梯(ti)(ti)過(guo)程(cheng)(cheng)中(zhong)(zhong)的(de)(de)(de)(de)(de)安(an)(an)全(quan)。

如何保(bao)證乘客總是(shi)處在安全空間呢(ni)？

(4)門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)的(de)(de)(de)(de)作用(yong)(yong)。門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)裝(zhuang)在(zai)(zai)層(ceng)門(men)(men)(men)(men)(men)(men)(men)(men)上(shang)，是(shi)使層(ceng)門(men)(men)(men)(men)(men)(men)(men)(men)保持(chi)關(guan)閉(bi)(bi)的(de)(de)(de)(de)裝(zhuang)置(zhi)。在(zai)(zai)鎖(suo)(suo)(suo)(suo)(suo)住層(ceng)門(men)(men)(men)(men)(men)(men)(men)(men)時，沿開(kai)門(men)(men)(men)(men)(men)(men)(men)(men)方(fang)向用(yong)(yong)小(xiao)于300n的(de)(de)(de)(de)力(li)不(bu)(bu)會使門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)降低(di)鎖(suo)(suo)(suo)(suo)(suo)緊效能，用(yong)(yong)小(xiao)于1 000n的(de)(de)(de)(de)力(li)不(bu)(bu)會使鎖(suo)(suo)(suo)(suo)(suo)緊元件出現變形。門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)有(you)(you)防(fang)粉塵、耐(nai)震(zhen)動(dong)、易(yi)檢查(cha)等特點。在(zai)(zai)一(yi)般情況下，門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)只能被轎(jiao)(jiao)門(men)(men)(men)(men)(men)(men)(men)(men)打(da)開(kai)。在(zai)(zai)特殊情況下，可以由(you)專門(men)(men)(men)(men)(men)(men)(men)(men)人員用(yong)(yong)鑰匙(chi)打(da)開(kai)。除機(ji)械裝(zhuang)置(zhi)外門(men)(men)(men)(men)(men)(men)(men)(men)鎖(suo)(suo)(suo)(suo)(suo)還有(you)(you)一(yi)個電(dian)(dian)(dian)氣裝(zhuang)置(zhi)，即與(yu)層(ceng)門(men)(men)(men)(men)(men)(men)(men)(men)保持(chi)同步閉(bi)(bi)合(he)或打(da)開(kai)的(de)(de)(de)(de)安(an)全(quan)(quan)觸(chu)點，它負責向控制(zhi)柜提(ti)供層(ceng)門(men)(men)(men)(men)(men)(men)(men)(men)是(shi)否關(guan)閉(bi)(bi)的(de)(de)(de)(de)信息。轎(jiao)(jiao)門(men)(men)(men)(men)(men)(men)(men)(men)上(shang)有(you)(you)一(yi)組同樣的(de)(de)(de)(de)安(an)全(quan)(quan)觸(chu)點。這些安(an)全(quan)(quan)觸(chu)點與(yu)其他重要部位(wei)的(de)(de)(de)(de)許多(duo)安(an)全(quan)(quan)觸(chu)點一(yi)起串聯在(zai)(zai)安(an)全(quan)(quan)回(hui)路中，只要有(you)(you)一(yi)組安(an)全(quan)(quan)觸(chu)點未閉(bi)(bi)合(he)，電(dian)(dian)(dian)梯便(bian)不(bu)(bu)能通電(dian)(dian)(dian)運行。通過以上(shang)措施，電(dian)(dian)(dian)梯就(jiu)確(que)保了乘客要么(me)呆在(zai)(zai)樓層(ceng)上(shang)，要么(me)呆在(zai)(zai)轎(jiao)(jiao)廂(xiang)里，而不(bu)(bu)會進入井道里。

根據(ju)質量(liang)監督檢驗檢疫總局的統(tong)計，電梯在安(an)裝(zhuang)、維(wei)修(xiu)施工中和正常運行中出(chu)現的人身傷亡(wang)事(shi)故只(zhi)有10%是(shi)(shi)電梯產品(pin)質量(liang)造成(cheng)的，有90% 是(shi)(shi)管理不(bu)善、私(si)自改(gai)裝(zhuang)等造成(cheng)的。所以，雖然電梯具(ju)備了保(bao)證乘客安(an)全(quan)的功能(neng)，但還不(bu)能(neng)因此就可以高枕無(wu)憂(you)了。實踐證明：只(zhi)有在完(wan)善的科(ke)學的管理環境下電梯的安(an)全(quan)功能(neng)才能(neng)得(de)以保(bao)持。

電梯是一(yi)種非(fei)常安全(quan)(quan)的交通(tong)工具，只須(xu)將良(liang)好的管理和文(wen)明(ming)的操作相配合，便完全(quan)(quan)有能力(li)給(gei)乘客提供安全(quan)(quan)的服務(wu)。
