1監控垂直吊裝是開發新一代起重機的首要目標1.1垂直吊裝是起重機安全作業基本要求起重機穩定性差其吊鉤偏角不得超過3還hai有you吊diao鉤gou不bu垂chui直zhi起qi吊diao重zhong物wu擺bai動dong可ke能neng傷shang及ji周zhou圍wei設she備bei和he人ren員yuan，尤you其qi是shi大da仰yang角jiao下xia的de不bu垂chui直zhi抬tai吊diao破po壞huai了le起qi重zhong機ji載zai荷he的de正zheng常chang分fen配pei
，故gu垂chui直zhi吊diao裝zhuang是shi起qi重zhong機ji安an全quan作zuo業ye的de基ji本ben要yao求qiu，然ran而er起qi重zhong機ji自zi身shen卻que沒mei有you垂chui直zhi吊diao裝zhuang的de顯xian示shi、監視設置以至於起重機司機無法判斷單機滑移法或旋轉法吊裝以及雙機
、三機吊裝時其吊鉤是否處於垂直狀態而要由吊裝指揮者，依據監視被吊重物垂直吊裝者提供的信息指揮司機操縱既不及時又不準確。

 

1.2起qi重zhong機ji抬tai吊diao的de危wei險xian來lai自zi大da仰yang角jiao下xia的de不bu垂chui直zhi吊diao裝zhuang由you於yu輔fu機ji抬tai送song速su度du與yu主zhu機ji提ti升sheng速su度du之zhi比bi值zhi
，依yi據ju速su度du按an影ying定ding理li應ying等deng於yu主zhu機ji與yu輔fu機ji吊diao點dian間jian連lian線xian的de斜xie率lv（斜率）才能實現垂直吊裝若此時仰角為77，則輔機抬送速度與主機提升速度之比值高達433，且吊裝中斜率不斷改變，因而沒有主、輔機間的密切配合是難以實現垂直吊裝
；同時主
、輔機吊鉤產生的（主、輔機間）偏角大小與主、輔機各自承擔的載荷成反比若主、輔機各自承擔載荷為6：1，當主機吊鉤偏角滯後0.5（尚不易覺察）
，而輔機吊鉤偏角竟超前3

，從吊裝數學模型看起重機不垂直吊裝的風險可知若按此時仰角為77計算輔機承擔的載荷竟是吊鉤偏角0時的1.297beigudayangjiaoxiadebuchuizhitaidiaopohuaileqizhongjizaihedezhengchangfenpei，yinertaidiaoshibijiaoweixiandezuoye，duidiaozhuangzhihuijisijiyaoqiudoubijiaogao。guowaiyouxiegongchengguanlirenyuanduiyushuangjitaidiaozuoyeshichifoudingtaidude“。

 

1.3垂直吊裝是實現起重機恒抬吊力吊裝的先決條件1.3.1恒抬吊力吊裝及其優勢依據受力明確且普遍適用的、反映吊裝力三要素間關係的、起重吊裝受力控製的數學模型
，起重機抬吊的吊點載荷變化原因之一是被吊重物重心偏離三吊點確定的平麵（吊點平麵）變化的原因之二是不垂直吊裝
，因而三吊點與被吊重物重心共麵設置

、分配梁，使起重吊裝高度大幅度下降（以百米高塔的二主機與輔機遞送吊裝為例采用平衡梁時主機吊裝高度顯然超過百米而恒抬吊力吊裝時主機吊裝高度隻需略高於塔體重心）且“diaochetaidiaofadiaozhuanggongyishicaiyongdanzhudiaochehuoshuangzhudiaochetishengwozhishebeideshangbu

，由(you)於(yu)在(zai)激(ji)光(guang)發(fa)生(sheng)器(qi)自(zi)重(zhong)和(he)球(qiu)絞(jiao)自(zi)動(dong)調(tiao)整(zheng)下(xia)，在(zai)起(qi)重(zhong)機(ji)工(gong)作(zuo)期(qi)間(jian)始(shi)絡(luo)發(fa)出(chu)鉛(qian)垂(chui)朝(chao)下(xia)的(de)基(ji)準(zhun)激(ji)光(guang)光(guang)束(shu)再(zai)通(tong)過(guo)安(an)設(she)的(de)探(tan)頭(tou)

；將(jiang)提(ti)升(sheng)滑(hua)輪(lun)組(zu)的(de)提(ti)升(sheng)與(yu)激(ji)光(guang)光(guang)束(shu)畫(hua)麵(mian)，經(jing)具(ju)有(you)單(dan)獨(du)將(jiang)圄(yu)像(xiang)橫(heng)向(xiang)放(fang)大(da)功(gong)能(neng)的(de)專(zhuan)用(yong)計(ji)算(suan)機(ji)軟(ruan)件(jian)顯(xian)示(shi)於(yu)司(si)機(ji)操(cao)作(zuo)台(tai)旁(pang)的(de)屏(ping)幕(mu)上(shang)。由(you)於(yu)單(dan)獨(du)將(jiang)圄(yu)像(xiang)橫(heng)向(xiang)放(fang)大(da)，鉛(qian)垂(chui)的(de)直(zhi)線(xian)方(fang)向(xiang)不(bu)變(bian)
，而(er)非(fei)鉛(qian)垂(chui)直(zhi)線(xian)的(de)斜(xie)率(lv)絕(jue)對(dui)值(zhi)則(ze)變(bian)小(xiao)，因(yin)而(er)吊(diao)裝(zhuang)時(shi)司(si)機(ji)可(ke)以(yi)鉛(qian)垂(chui)朝(chao)下(xia)的(de)激(ji)光(guang)光(guang)束(shu)為(wei)基(ji)準(zhun)，參(can)看(kan)提(ti)升(sheng)滑(hua)輪(lun)組(zu)提(ti)升(sheng)繩(sheng)偏(pian)斜(xie)角(jiao)度(du)被(bei)放(fang)大(da)的(de)畫(hua)麵(mian)調(tiao)控(kong)起(qi)重(zhong)機(ji)吊(diao)裝(zhuang)消(xiao)除(chu)吊(diao)鉤(gou)偏(pian)角(jiao)實(shi)現(xian)起(qi)重(zhong)機(ji)的(de)垂(chui)直(zhi)吊(diao)裝(zhuang)。

 

2.2設(she)吊(diao)車(che)吊(diao)鉤(gou)偏(pian)角(jiao)激(ji)光(guang)顯(xian)示(shi)與(yu)監(jian)視(shi)設(she)置(zhi)監(jian)控(kong)起(qi)重(zhong)由(you)於(yu)控(kong)製(zhi)起(qi)重(zhong)機(ji)垂(chui)直(zhi)吊(diao)裝(zhuang)的(de)核(he)心(xin)是(shi)控(kong)製(zhi)其(qi)吊(diao)鉤(gou)的(de)偏(pian)角(jiao)
，吊(diao)車(che)吊(diao)鉤(gou)偏(pian)角(jiao)激(ji)光(guang)顯(xian)示(shi)與(yu)監(jian)視(shi)設(she)置(zhi)即(ji)實(shi)現(xian)對(dui)起(qi)重(zhong)機(ji)吊(diao)鉤(gou)偏(pian)角(jiao)的(de)動(dong)態(tai)顯(xian)示(shi)，在(zai)用(yong)激(ji)光(guang)作(zuo)為(wei)起(qi)重(zhong)機(ji)垂(chui)直(zhi)吊(diao)裝(zhuang)基(ji)準(zhun)的(de)同(tong)時(shi)又(you)用(yong)激(ji)光(guang)顯(xian)示(shi)起(qi)重(zhong)機(ji)吊(diao)鉤(gou)的(de)偏(pian)斜(xie)直(zhi)觀(guan)、鮮明
，並依此控製起重機銷除吊鉤的偏角。其作法是：首先將經球絞連接、始絡發射鉛垂朝上激光光束的基準激光發生器，裝設於與起重機吊鉤相聯的動滑輪護夾板外側的下方位置。

 

接著將吊鉤偏角激光發生器，裝設於與起重機吊鉤相聯的動滑輪護夾板外側的上方位置，且滿足起重機吊鉤偏角0時，吊鉤偏角激光發生器朝下發射（若為蘭色）的激光光束中心線與基準激光發生器鉛垂朝上發射（若為紅色）的激光光束中心線相重合。因而當吊鉤偏角0時紅色與蘭色相混發出紫光，當吊鉤產生偏角時，蘭色激光光束則偏離紅色的基準激光光束紅、蘭分明顯示出偏角的方向和偏斜的程度。
