时间:2022-11-05 16:37:08 浏览量:9


单梁起重机电(dian)气设备(bei)(bei)的(de)(de)(de)维护(hu)和(he)(he)维护(hu):为(wei)了(le)保证(zheng)起(qi)重机的(de)(de)(de)可靠性和(he)(he)安全性(job),要制定符合(he)GB6067-85要求的(de)(de)(de)电(dian)气设备(bei)(bei)维护(hu)制度,熟悉设备(bei)(bei)各种故障(zhang)(fault)的(de)(de)(de)原因和(he)(he)消(xiao)除故障(zhang)的(de)(de)(de)方法。主要电(dian)气设备(bei)(bei)的(de)(de)(de)维护(hu)如下:1。为(wei)了(le)提(ti)高起(qi)重机电(dian)气设备(bei)(bei)的(de)(de)(de)使用寿命(use),应始终保持控制(control)箱(xiang)内接触器(contactor)等电(dian)气设备(bei)(bei)的(de)(de)(de)清洁。


使用电缆导电时,应随(sui)时清除汽车滑轨(gui)(TTWguide)上的角(jiao)锈和污(wu)垢,保持牵引滑车正常(chang)运行。检查轨(gui)道:主要观察轨(gui)道是(shi)否(fou)(fou)平直,压(ya)板是(shi)否(fou)(fou)牢(lao)固(gu),是(shi)否(fou)(fou)松动。如果发(fa)现(xian)汽车行走时卡(ka)住轨(gui)道,应尽(jin)量纠正轨(gui)道或调(diao)整车轮。


单梁起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)安(an)全(safe)操(cao)作(zuo)(operate)规程(cheng):不(bu)允许吊装物品(pin)在空中(zhong)长(zhang)时间停留;吊装物品(pin)时,工作(zuo)人员(yuan)不(bu)得离开工作(zuo)岗(gang)位(wei)。起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)是指在一定(ding)范围内垂直提(ti)升和水(shui)平搬运(yun)重(zhong)(zhong)(zhong)(zhong)物的(de)多(duo)动(dong)作(zuo)起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)械。又称天(tian)车、航空起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)、起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)。起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)的(de)主要参数是表征起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)主要技术性能指标的(de)参数,是起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)设(she)计和安(an)全技术要求(qiu)的(de)基(ji)础。严(yan)禁(jin)酒后(hou)操(cao)作(zuo)。工作(zuo)时严(yan)禁(jin)闲聊。工作(zuo)结束后(hou),将(jiang)起(qi)(qi)(qi)重(zhong)(zhong)(zhong)(zhong)机(ji)(ji)(ji)(ji)开回大门左侧停放(fang),将(jiang)操(cao)作(zuo)按钮(niu)开关挂(gua)(gua)在指定(ding)位(wei)置(position)。挂(gua)(gua)操(cao)作(zuo)按钮(niu)开关时要注意(attention):取下前怎么(me)挂(gua)(gua),放(fang)回去怎么(me)挂(gua)(gua),防(fang)止雨水(shui)流入按钮(niu)开关。

1.组装运行(Windows)车(che)辆。


运行(Windows)的车辆首先用固(gu)定销(xiao)安装在轨道上,用螺(luo)栓(组(zu)成:头部和螺(luo)钉)紧(jin)固(gu)。悬臂起重(zhong)机属于工(gong)(gong)业部件,是一(yi)种轻(qing)型工(gong)(gong)作强度起重(zhong)机,由柱、旋(xuan)转臂旋(xuan)转驱动(dong)(dong)装置和电(dian)动(dong)(dong)葫(hu)芦组(zu)成,重(zhong)量(liang)轻(qing),跨度大,起重(zhong)量(liang)大,经济耐(nai)用。主动(dong)(dong)轮应(ying)与(yu)轨道表(biao)面接触,被动(dong)(dong)轮与(yu)轨道表(biao)面之间的间隙应(ying)满足电(dian)动(dong)(dong)葫(hu)芦桥(qiao)式起重(zhong)机的标(biao)准要求。组(zu)装小(xiao)车后,其主要尺寸偏差应(ying)符合电(dian)动(dong)(dong)单梁桥(qiao)式起重(zhong)机标(biao)准的要求。


2.安装主梁。


主梁(liang)强度(du)(du)(strength)螺栓(组成(cheng):头部(bu)和螺钉)连(lian)接(jie)主梁(liang)和端梁(liang),组装成(cheng)桥架结构(structure)。电动(dong)葫芦结构紧凑,垂直于滚筒轴的(de)电动(dong)葫芦采用蜗轮(lun)传动(dong)装置。缺点是(shi):长度(du)(du)尺寸(cun)大,宽(kuan)度(du)(du)大,结构笨重(zhong),机械效率低,加(jia)工困(kun)难。液压(ya)(ya)系统为(wei)双(shuang)重(zhong)控(kong)制,溢流调节阀和磁接(jie)点压(ya)(ya)力(li)表可(ke)准确控(kong)制压(ya)(ya)力(li)。电气(qi)控(kong)制部(bu)采用低压(ya)(ya)控(kong)制,提(ti)高了控(kong)制系统的(de)安(an)全性。
