4.1顶板梁上梁平放、翻立和吊装简介Briefintroductionofhorizontallaying,turningandliftingofthetopceilinggirder
大板梁均由LR1400/2型液压履带吊单车平放、翻立及吊装就位。
Alltheceilinggirdersshouldbehorizontallylaid,turnedandliftedbyLR1400/2hydrauliccrawlercrane.
LR1400/2型液压履带吊布置在B2和B4列柱之间,回转中心与锅炉纵向中心线重合,沿锅炉前后方向移动,顶板梁全部平放在K5排柱后进行翻立和吊装。
TheLR1400/2craneshouldbearrangedbetweenB2andB4.Therotarycentershouldbecoincidewiththeboilerlongitudinalcenterline.Itshouldbemovedalongtheboilerfront-reardirection.AlltheceilinggirdersareturnedandliftedbyhorizontallylayingbehindtheK5row.MB1、MB2、MB3和MB5顶板梁从K5排柱后起吊后直接向炉前走车,走到就位位置后转杆180°,然后就位固定。
Theceilinggirders(MB1,MB2,MB3,MB5)shouldbeliftedbehindK5rowanddirectlybemovedtothefrontofboiler.Afterreachingthecorrectlocation,theboomshouldbeturned180°andbefixed.MB-4顶板梁吊装时直接将吊车走到就位位置,起吊后转杆直接就位固定,DirectlyarrangethecraneonthecorrectlocationwhenliftingtheMB4ceilinggirder.Theboomshouldbefixedafterlifting,顶板梁放置位置可参考以下顺序thelayoutlocationoftheceilinggirdercanreferthefollowingsequence:
MB-1顶板梁放置在离K5排柱中心线2000mm处,MB-1ceilinggirdershouldbelaid2000mmfarawayfromcenterlineofK5row,MB-2下梁放置在离K5排柱中心线5000mm处,bottomceilinggirderofMB-2shouldbelaid5000mmawayfromcenterlineofK5row,MB2上梁放置在离K5排柱中心线8000mm处,topceilinggirderofMB-2shouldbelaid8000mmfarawayfromcenterlineofK5row,MB-3顶板梁下梁放置在离K5柱中心线11000mm处,bottomceilinggirderofMB-3shouldbelaid11000mmfarawayfromcenterlineofK5row,MB-3顶板梁上梁放置在K5排柱中心线14000mm处,topceilinggirderofMB-3shouldbelaid14000mmfarawayfromcenterlineofK5row,MB-4下梁放置在离K5排柱中心线17000mm处,bottomceilinggirderofMB-4shouldbelaid17000mmfarawayfromcenterlineofK5row,MB-4上梁放置在离K5排柱中心线21600mm处,topceilinggirderofMB-4shouldbelaid21600mmfarawayfromcenterlineofK5row,MB5顶板梁放置在离K5排柱中心线25000mm处,MB5ceilinggirdershouldbelaid25000mmfarawayfromcenterlineofK5row,放置时所有顶板梁的横向中心线应尽量与锅炉纵向中心线重合.Duringthelaying,allthetransversecenterlinesoftheceilinggirdersshouldbecoincidewiththeboilerlongitudinalcenterlines.
因为MB-2、MB-3、MB-4顶板梁上梁设备到货时均为上翼板向下,所以应先将上梁翻转180°,使上翼板向上才能满足就位要求。
MB-2、MB-3和MB-4上梁均由LR1400/2型履带吊单车进行平放及翻立。
WhentheMB-2,MB-3,MB-4ceilinggirdersreachsite,thetopgirdersareupward,sothetopgirdershouldbeoverturned180°untilthetopgirdersatisfytheerectionrequirement.ThetopgirdersofMB-2,MB-3andMB-4shouldbelaidandoverturnedbyLR1400/2crawlercrane.
因吊车起吊高度有限,顶板梁长度又长,顶板梁起吊后不能随意转动,顶板梁纵向中心线应始终与吊车主臂保持垂直,所以平放和翻立后应保证顶板梁就位时方向正确.
Becausethecraneliftingheightislimited,andtheceilinggirdersarebigandheavy,theceilinggirderscannotbearbitrarilyturnedafterlifting,thelongitudinalcenterlineoftheceilinggirdershouldbeverticalwiththemainjibofthecraneduringthelifting.Theerectiondirectionoftheceilinggirdersshouldbekeptcorrectafterlayingandoverturning.
