對(dui)(dui)稱(cheng)道(dao)岔是我(wo)國煤(mei)礦窄(zhai)軌鐵路道(dao)岔的(de)一種類(lei)型,是窄(zhai)軌道(dao)鐵路線路連接的(de)基本設備。對(dui)(dui)稱(cheng)道(dao)岔標(biao)準化、系(xi)列化對(dui)(dui)煤(mei)礦或(huo)其(qi)他礦山的(de)設計、建設和生(sheng)產也是非(fei)常(chang)重要的(de)。
3、判(pan)斷是(shi)(shi)道(dao)岔(cha)(cha)室(shi)內(nei)還是(shi)(shi)室(shi)外(wai)的(de)原(yuan)因①如果(guo)(guo)(guo)是(shi)(shi)單動(dong)(dong)(dong)(dong)道(dao)岔(cha)(cha),在(zai)操(cao)動(dong)(dong)(dong)(dong)時控制(zhi)臺(tai)(tai)的(de)電(dian)(dian)(dian)(dian)流表有指示,說明(ming)(ming)動(dong)(dong)(dong)(dong)作(zuo)道(dao)岔(cha)(cha)的(de)電(dian)(dian)(dian)(dian)已(yi)送至(zhi)到道(dao)岔(cha)(cha)。如果(guo)(guo)(guo)這時道(dao)岔(cha)(cha)不能(neng)操(cao)到規定位(wei)置(zhi),是(shi)(shi)室(shi)外(wai)原(yuan)因。在(zai)操(cao)動(dong)(dong)(dong)(dong)道(dao)岔(cha)(cha)時,如果(guo)(guo)(guo)控制(zhi)臺(tai)(tai)的(de)電(dian)(dian)(dian)(dian)流表沒(mei)有指示,首先到機械室(shi)的(de)室(shi)外(wai)分線盤(pan)測量(liang)(liang)該道(dao)岔(cha)(cha)有沒(mei)有電(dian)(dian)(dian)(dian)壓(ya),如果(guo)(guo)(guo)有電(dian)(dian)(dian)(dian)壓(ya)說明(ming)(ming)動(dong)(dong)(dong)(dong)作(zuo)道(dao)岔(cha)(cha)的(de)電(dian)(dian)(dian)(dian)已(yi)送出(chu),是(shi)(shi)室(shi)外(wai)故(gu)(gu)障(zhang)。②如果(guo)(guo)(guo)是(shi)(shi)雙動(dong)(dong)(dong)(dong)道(dao)岔(cha)(cha),在(zai)操(cao)動(dong)(dong)(dong)(dong)時控制(zhi)臺(tai)(tai)的(de)電(dian)(dian)(dian)(dian)流表動(dong)(dong)(dong)(dong)一下就不動(dong)(dong)(dong)(dong)了,說明(ming)(ming)動(dong)(dong)(dong)(dong)作(zuo)道(dao)岔(cha)(cha)的(de)電(dian)(dian)(dian)(dian)已(yi)送到了一動(dong)(dong)(dong)(dong)道(dao)岔(cha)(cha),故(gu)(gu)障(zhang)出(chu)在(zai)一動(dong)(dong)(dong)(dong)道(dao)岔(cha)(cha)以后(hou),是(shi)(shi)室(shi)外(wai)故(gu)(gu)障(zhang)。③如果(guo)(guo)(guo)道(dao)岔(cha)(cha)定、反位(wei)都能(neng)操(cao)動(dong)(dong)(dong)(dong),就是(shi)(shi)沒(mei)有表示。用萬(wan)用表交(jiao)流250v檔,在(zai)分線盤(pan)測量(liang)(liang)X1(或X2)與X3間有無交(jiao)流110V左右電(dian)(dian)(dian)(dian)壓(ya),如果(guo)(guo)(guo)有電(dian)(dian)(dian)(dian)壓(ya),則(ze)是(shi)(shi)室(shi)外(wai)故(gu)(gu)障(zhang),否則(ze)是(shi)(shi)室(shi)內(nei)故(gu)(gu)障(zhang)。
