起重机钢丝绳使用指南

来源:techb4u.com         发布时间:2019-08-14

今天昆明钢绳来讲讲起重机钢丝绳使用指南。 绳夹应从吊装点处依次夹紧,并在后一个绳夹和前一个绳夹间,应使钢丝绳有少许拱起。

1、施工突(tu)然停(ting)电(dian)(dian);’施工中突(tu)然停(ting)电(dian)(dian)时(shi)(shi),应(ying)立(li)即切断电(dian)(dian)箱电(dian)(dian)源(yuan)开关(guan),防止(zhi)送电(dian)(dian)时(shi)(shi)发生(sheng)意外,待接到来电(dian)(dian)通知后(hou)再合上电(dian)(dian)源(yuan)开关(guan),并经检(jian)查正(zheng)常后(hou)开始工作(zuo)。如停(ting)电(dian)(dian)后(hou)需返回地面(mian)时(shi)(shi),应(ying)同时(shi)(shi)抬起两端提升机电(dian)(dian)机的手(shou)动滑降手(shou)柄,使悬吊平台自由(you)滑降至地面(mian)。

2、悬(xuan)吊(diao)平台(tai)升(sheng)、降(jiang)(jiang)过(guo)程(cheng)中(zhong)松开(kai)(kai)按(an)钮(niu)(niu)后(hou)不(bu)能停止。悬(xuan)吊(diao)平台(tai)在升(sheng)、降(jiang)(jiang)过(guo)程(cheng)中(zhong)如松开(kai)(kai)按(an)钮(niu)(niu)后(hou)仍不(bu)能停止时,应(ying)立即按(an)下电(dian)箱(xiang)门上的红(hong)色(se)紧(jin)停开(kai)(kai)关(guan),使悬(xuan)吊(diao)平台(tai)紧(jin)急停止。然(ran)后(hou)切断电(dian)箱(xiang)电(dian)源开(kai)(kai)关(guan),检查(cha)接(jie)触器接(jie)触情(qing)况,清理接(jie)触器表(biao)面粘附(fu)油垢杂质,手按(an)接(jie)触器能恢(hui)复正常动(dong)作(zuo)后(hou),合上电(dian)源开(kai)(kai)关(guan),旋动(dong)紧(jin)停开(kai)(kai)关(guan)使其恢(hui)复原位后(hou)继续工作(zuo)。如故(gu)障(zhang)仍不(bu)能排除时,应(ying)切断电(dian)源开(kai)(kai)关(guan),采(cai)用手动(dong)滑(hua)降(jiang)(jiang)方法将(jiang)悬(xuan)吊(diao)平台(tai)降(jiang)(jiang)至地面进(jin)行检修。

3、悬(xuan)吊(diao)(diao)平(ping)(ping)(ping)台因水平(ping)(ping)(ping)倾(qing)斜而自动(dong)锁(suo)(suo)(suo)绳悬(xuan)吊(diao)(diao)平(ping)(ping)(ping)台在(zai)升、降(jiang)过程中(zhong)或(huo)一(yi)端滑降(jiang)面水平(ping)(ping)(ping)倾(qing)斜至一(yi)定范围时,安全锁(suo)(suo)(suo)自动(dong)锁(suo)(suo)(suo)绳,此(ci)时应(ying)立即停(ting)机(ji),然(ran)后将电(dian)箱上的转(zhuan)(zhuan)换开关转(zhuan)(zhuan)向(xiang)平(ping)(ping)(ping)台低端,再按上升按钮将悬(xuan)吊(diao)(diao)平(ping)(ping)(ping)台降(jiang)至地面,检(jian)查并调整两端提(ti)升机(ji)中(zhong)电(dian)磁制动(dong)器(qi)。间隙至符合要(yao)求;或(huo)检(jian)查两端电(dian)机(ji)转(zhuan)(zhuan)速差异(yi),如差异(yi)明显应(ying)更换电(dian)机(ji)。

4、安全(quan)(quan)(quan)(quan)(quan)锁(suo)在(zai)工(gong)(gong)(gong)作(zuo)时应该时开启的,处于自动(dong)(dong)工(gong)(gong)(gong)作(zuo)状态,无需(xu)人工(gong)(gong)(gong)操(cao)作(zuo)。它(ta)的作(zuo)用是当提升(sheng)系(xi)统出现故障而导致吊(diao)篮超速下降时,能自动(dong)(dong)锁(suo)定在(zai)安全(quan)(quan)(quan)(quan)(quan)钢丝绳上(shang),使吊(diao)篮停止下降保证人机安全(quan)(quan)(quan)(quan)(quan)。当故障排除,需(xu)重(zhong)新(xin)打开安全(quan)(quan)(quan)(quan)(quan)锁(suo)时,首先应点动(dong)(dong)吊(diao)篮上(shang)升(sheng),使安全(quan)(quan)(quan)(quan)(quan)锁(suo)稍松后,方可扳动(dong)(dong)开启手(shou)柄,打开安全(quan)(quan)(quan)(quan)(quan)锁(suo)。严禁(jin)在(zai)安全(quan)(quan)(quan)(quan)(quan)钢丝绳绷紧情况下,硬(ying)性扳动(dong)(dong)开启手(shou)柄,以免损坏(huai)安全(quan)(quan)(quan)(quan)(quan)锁(suo)。不要在(zai)安全(quan)(quan)(quan)(quan)(quan)锁(suo)锁(suo)闭后开动(dong)(dong)机器下降这样(yang)极易引起提升(sheng)机严重(zhong)损坏(huai)。

5、工作(zuo)钢(gang)丝(si)(si)(si)绳(sheng)因松(song)股,扭(niu)结或提升(sheng)(sheng)(sheng)机(ji)别件损坏(huai)而卡塞(sai)(sai)在(zai)(zai)提升(sheng)(sheng)(sheng)机(ji)内工作(zuo)钢(gang)丝(si)(si)(si)绳(sheng)发(fa)生卡塞(sai)(sai)在(zai)(zai)提升(sheng)(sheng)(sheng)机(ji)内时,应立即(ji)停机(ji)。严禁反复升(sheng)(sheng)(sheng)、降进(jin)(jin)行(xing)强(qiang)行(xing)解脱。在(zai)(zai)确保安(an)(an)全的(de)(de)情况下(xia),撤离悬吊平台内的(de)(de)施工人员(yuan),派遣经过专业(ye)培(pei)训的(de)(de)维修人员(yuan)进(jin)(jin)人悬吊平台进(jin)(jin)行(xing)维修。首先将安(an)(an)全钢(gang)丝(si)(si)(si)绳(sheng)缠绕(rao)于两(liang)端(duan)(duan)提升(sheng)(sheng)(sheng)机(ji)安(an)(an)装架上,用绳(sheng)扣将安(an)(an)全钢(gang)丝(si)(si)(si)绳(sheng)两(liang)端(duan)(duan)扣紧。然后(hou)松(song)开(kai)两(liang)安(an)(an)全锁摆臂(bei)滚(gun)轮的(de)(de)保护环,将工作(zuo)钢(gang)丝(si)(si)(si)绳(sheng)与滚(gun)轮脱开(kai),使两(liang)端(duan)(duan)安(an)(an)全锁处于锁绳(sheng)状态(tai)。在(zai)(zai)采取上述安(an)(an)全措施后(hou),取下(xia)提升(sheng)(sheng)(sheng)机(ji)检查,并退出卡塞(sai)(sai)的(de)(de)钢(gang)丝(si)(si)(si)绳(sheng),必要是(shi)可将故(gu)障钢(gang)丝(si)(si)(si)绳(sheng)截(jie)断和打开(kai)提升(sheng)(sheng)(sheng)机(ji)箱盖(gai)进(jin)(jin)行(xing)检查,并小心取出留在(zai)(zai)提升(sheng)(sheng)(sheng)机(ji)内的(de)(de)钢(gang)丝(si)(si)(si)绳(sheng)。

6、垂放(fang)(fang)钢(gang)丝(si)绳(sheng)(sheng)时(shi),应(ying)将钢(gang)丝(si)绳(sheng)(sheng)自(zi)由盘放(fang)(fang)在楼面(mian),将绳(sheng)(sheng)头仔细抽出后(hou)沿前面(mian)缓慢向(xiang)下滑(hua)放(fang)(fang),严禁将钢(gang)丝(si)绳(sheng)(sheng)成盘向(xiang)下抛放(fang)(fang)。
