醫用電梯服(fu)務于(yu)規定(ding)樓層(ceng)的固定(ding)式(shi)升降(jiang)設(she)備。它(ta)具有一個(ge)轎廂(xiang)，運行在至少(shao)兩列垂直的或(huo)傾斜(xie)角小于(yu)15°的鋼性(xing)導軌(gui)之間。轎廂(xiang)尺(chi)寸與(yu)結構(gou)型式(shi)便于(yu)乘客出入。

醫用電梯的(de)工作原理：

曳(ye)(ye)引(yin)(yin)(yin)繩兩端分別連著轎廂和對重，纏繞(rao)在曳(ye)(ye)引(yin)(yin)(yin)輪和導向輪上，曳(ye)(ye)引(yin)(yin)(yin)電(dian)動機通過(guo)減速(su)器變速(su)后帶動曳(ye)(ye)引(yin)(yin)(yin)輪轉(zhuan)動，靠曳(ye)(ye)引(yin)(yin)(yin)繩與曳(ye)(ye)引(yin)(yin)(yin)輪摩擦產生的牽引(yin)(yin)(yin)力，

實(shi)現(xian)轎廂(xiang)和(he)(he)(he)對重(zhong)的(de)升降運(yun)動(dong)(dong)，達(da)到運(yun)輸目的(de)。固定(ding)(ding)在(zai)轎廂(xiang)上(shang)的(de)導靴(xue)可(ke)以(yi)沿著(zhu)安(an)裝在(zai)建(jian)筑物(wu)井道墻體上(shang)的(de)固定(ding)(ding)導軌往復(fu)升降運(yun)動(dong)(dong)，防止轎廂(xiang)在(zai)運(yun)行(xing)(xing)中偏(pian)斜或(huo)擺動(dong)(dong)。常閉塊式制(zhi)動(dong)(dong)器在(zai)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)工(gong)(gong)作(zuo)時松閘，使(shi)電(dian)(dian)(dian)(dian)梯運(yun)轉，在(zai)失電(dian)(dian)(dian)(dian)情況下(xia)制(zhi)動(dong)(dong)，使(shi)轎廂(xiang)停止升降，并在(zai)指定(ding)(ding)層(ceng)(ceng)站上(shang)維持(chi)其靜止狀(zhuang)態，供人(ren)員和(he)(he)(he)貨物(wu)出入。轎廂(xiang)是運(yun)載(zai)乘客(ke)或(huo)其他載(zai)荷的(de)箱體部件，對重(zhong)用(yong)來平(ping)衡轎廂(xiang)載(zai)荷、減少電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)功率。補(bu)償(chang)(chang)裝置用(yong)來補(bu)償(chang)(chang)曳引(yin)繩運(yun)動(dong)(dong)中的(de)張(zhang)力和(he)(he)(he)重(zhong)量變化，使(shi)曳引(yin)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)負載(zai)穩定(ding)(ding)，轎廂(xiang)得以(yi)準(zhun)確停靠。電(dian)(dian)(dian)(dian)氣(qi)系統實(shi)現(xian)對電(dian)(dian)(dian)(dian)梯運(yun)動(dong)(dong)的(de)控制(zhi)，同時完成選層(ceng)(ceng)、平(ping)層(ceng)(ceng)、測速、照(zhao)明工(gong)(gong)作(zuo)。指示呼叫(jiao)系統隨時顯示轎廂(xiang)的(de)運(yun)動(dong)(dong)方向和(he)(he)(he)所在(zai)樓層(ceng)(ceng)位置。安(an)全裝置保(bao)證電(dian)(dian)(dian)(dian)梯運(yun)行(xing)(xing)安(an)全。
