LX型電動單梁懸掛起重機運行扭擺問題

    LX型電動單梁懸掛起重機運行扭擺問題

    LX型xing電dian動dong單dan梁liang懸xuan掛gua起qi重zhong機ji的de發fa動dong和he製zhi動dong是shi經jing過guo驅qu動dong輪lun與yu工gong字zi鋼gang軌gui跡ji的de摩mo擦ca來lai實shi現xian的de。假jia如ru起qi重zhong機ji端duan梁liang兩liang邊bian驅qu動dong輪lun的de摩mo擦ca力li不bu一yi致zhi

，則ze會hui發fa生sheng改gai變bian搖yao擺bai。

    啟停時有兩種情況：一種是一側電機損壞，製動器失效；另ling一yi種zhong是shi端duan梁liang驅qu動dong輪lun摩mo擦ca力li過guo小xiao或huo懸xuan空kong。經jing丈zhang量liang，電dian機ji狀zhuang況kuang良liang好hao，製zhi動dong器qi無wu故gu障zhang。也ye就jiu是shi說shuo，問wen題ti是shi由you驅qu動dong輪lun的de懸xuan掛gua引yin起qi的de啟qi停ting扭niu擺bai引yin起qi的de。LX型電動單梁懸掛起重機運行扭擺原因有四個：

    由於軌跡根底的變形和沉陷，工字鋼軌的下翼緣不均勻，I形鋼軌自身的變形出現偏差，車輪尾部的損害不同
，形成運轉進程中的差錯；對角線差錯超越JB∥n2603-94lx電(dian)動(dong)單(dan)梁(liang)懸(xuan)掛(gua)起(qi)重(zhong)機(ji)的(de)技(ji)能(neng)要(yao)求(qiu)。在(zai)這(zhe)兩(liang)種(zhong)情(qing)況(kuang)下(xia)，發(fa)動(dong)時(shi)，驅(qu)動(dong)輪(lun)不(bu)能(neng)與(yu)工(gong)字(zi)鋼(gang)軌(gui)跡(ji)踏(ta)麵(mian)觸(chu)摸(mo)，驅(qu)動(dong)輪(lun)滾(gun)動(dong)但(dan)不(bu)能(neng)有(you)效(xiao)行(xing)走(zou)

    LX型電動單梁懸掛起重機裝置標準中
，單側輪軌空隙差錯答應為3～5mm。這樣
，起重機車輪與工字鋼軌跡之間有必定的空隙
