單梁橋式起重機衝頂原因

    單梁橋式起重機衝頂原因

    在我去廠家更換單梁橋式起重機上的電動葫蘆之前，主要問題是電動葫蘆衝頂，所以新的3T電(dian)動(dong)葫(hu)蘆(lu)報(bao)廢(fei)了(le)。原(yuan)因(yin)是(shi)土(tu)建(jian)人(ren)員(yuan)使(shi)用(yong)單(dan)梁(liang)橋(qiao)式(shi)起(qi)重(zhong)機(ji)吊(diao)起(qi)物(wu)體(ti)時(shi)，未(wei)經(jing)許(xu)可(ke)安(an)裝(zhuang)了(le)單(dan)梁(liang)橋(qiao)式(shi)起(qi)重(zhong)機(ji)的(de)電(dian)源(yuan)線(xian)，導(dao)致(zhi)單(dan)梁(liang)橋(qiao)式(shi)起(qi)重(zhong)機(ji)的(de)上(shang)限(xian)失(shi)效(xiao)而(er)直(zhi)接(jie)撞(zhuang)到(dao)頂(ding)部(bu)。

    員yuan工gong疏shu忽hu。由you於yu單dan梁liang橋qiao式shi起qi重zhong機ji的de吊diao鉤gou被bei控kong製zhi器qi的de手shou柄bing拉la動dong，因yin此ci在zai工gong作zuo期qi間jian，如ru果guo工gong人ren操cao作zuo不bu當dang，則ze牽qian引yin控kong製zhi器qi的de手shou柄bing將jiang無wu法fa處chu於yu正zheng確que的de位wei置zhi，例li如ru，不bu會hui被bei拉la動dong歸gui零ling。這zhe將jiang導dao致zhi吊diao鉤gou繼ji續xu上shang升sheng
，從cong而er導dao致zhi翻fan倒dao，甚shen至zhi發fa生sheng事shi故gu。

    限(xian)位(wei)器(qi)的(de)檢(jian)查(zha)不(bu)好(hao)。單(dan)梁(liang)橋(qiao)式(shi)起(qi)重(zhong)機(ji)的(de)電(dian)動(dong)葫(hu)蘆(lu)限(xian)製(zhi)器(qi)的(de)主(zhu)要(yao)功(gong)能(neng)是(shi)在(zai)吊(diao)裝(zhuang)過(guo)程(cheng)中(zhong)控(kong)製(zhi)吊(diao)鉤(gou)的(de)動(dong)作(zuo)。如(ru)果(guo)在(zai)操(cao)作(zuo)過(guo)程(cheng)中(zhong)未(wei)仔(zai)細(xi)檢(jian)查(zha)止(zhi)動(dong)塊(kuai)，則(ze)接(jie)頭(tou)很(hen)容(rong)易(yi)粘(zhan)住(zhu)。一(yi)旦(dan)發(fa)生(sheng)粘(zhan)連(lian)，限(xian)位(wei)器(qi)將(jiang)處(chu)於(yu)故(gu)障(zhang)狀(zhuang)態(tai)
，從(cong)而(er)導(dao)致(zhi)主(zhu)鉤(gou)子(zi)不(bu)斷(duan)上(shang)升(sheng)。在(zai)上(shang)升(sheng)過(guo)程(cheng)中(zhong)，鋼(gang)絲(si)繩(sheng)無(wu)法(fa)承(cheng)受(shou)壓(ya)力(li)的(de)衝(chong)擊(ji)而(er)折(zhe)斷(duan)

    沒mei有you定ding期qi檢jian查zha和he維wei護hu。對dui於yu舊jiu的de單dan梁liang橋qiao式shi起qi重zhong機ji電dian動dong葫hu蘆lu，應ying加jia強qiang檢jian查zha和he維wei護hu。定ding期qi檢jian查zha並bing排pai除chu故gu障zhang
，以yi免mian發fa生sheng使shi用yong中zhong的de故gu障zhang和he事shi故gu。起qi重zhong設she備bei有you很hen多duo配pei件jian。使shi用yong前qian
，您nin需xu要yao檢jian查zha所suo有you這zhe些xie配pei件jian的de故gu障zhang排pai除chu和he安an全quan性xing。但dan是shi，起qi重zhong設she備bei不bu同tong部bu分fen的de檢jian查zha方fang法fa和he步bu驟zhou不bu同tong。應ying根gen據ju每mei個ge零ling件jian的de特te性xing仔zai細xi檢jian查zha，以yi免mian對dui起qi重zhong設she備bei的de使shi用yong壽shou命ming造zao成cheng不bu利li影ying響xiang。

    首(shou)先(xian)要(yao)檢(jian)查(zha)的(de)是(shi)滑(hua)輪(lun)
，它(ta)是(shi)單(dan)梁(liang)橋(qiao)式(shi)起(qi)重(zhong)機(ji)的(de)附(fu)件(jian)之(zhi)一(yi)。檢(jian)查(zha)滑(hua)輪(lun)是(shi)否(fou)具(ju)有(you)防(fang)墜(zhui)槽(cao)裝(zhuang)置(zhi)，以(yi)及(ji)滑(hua)輪(lun)繩(sheng)槽(cao)和(he)輪(lun)緣(yuan)是(shi)否(fou)破(po)裂(lie)，折(zhe)疊(die)或(huo)過(guo)度(du)磨(mo)損(sun)。運(yun)行(xing)期(qi)間(jian)應(ying)確(que)保(bao)正(zheng)常(chang)運(yun)行(xing)。

    第di二er個ge是shi減jian速su器qi。在zai減jian速su器qi運yun行xing期qi間jian，請qing檢jian查zha是shi否fou有you異yi常chang聲sheng音yin，例li如ru嚴yan重zhong的de金jin屬shu摩mo擦ca聲sheng，振zhen動dong和he外wai殼ke輻fu射she聲sheng。同tong時shi，軸zhou端duan密mi封feng是shi否fou正zheng確que，固gu定ding螺luo栓shuan是shi否fou鬆song動dong或huo有you缺que陷xian以yi及ji減jian速su器qi潤run滑hua劑ji的de質zhi量liang和he數shu量liang也ye是shi關guan注zhu的de焦jiao點dian。
