*近屢(lv)創集裝(zhuang)箱(xiang)生產世界紀錄的青島(dao)港“**工人”許振(zhen)超再建(jian)奇(qi)功(gong),提出將(jiang)集裝(zhuang)箱(xiang)輪胎吊由內燃機驅(qu)動改為電驅(qu)動,并帶領他的團隊自主**,攻(gong)關成功(gong),填

補了集(ji)裝(zhuang)(zhuang)箱(xiang)輪(lun)胎吊“油改電”革(ge)新(xin)領(ling)域(yu)的世界空白。今日,青(qing)島(dao)港(gang)(gang)有關負責人在接受記者(zhe)采(cai)訪時稱(cheng),該(gai)項目在青(qing)島(dao)港(gang)(gang)**推廣后,年可節(jie)(jie)約成本 3000 萬元以上,相(xiang)當于“省(sheng)”出一個(ge)大型企業(ye)的資產。同時,該(gai)項目實施后,將極大地減(jian)少環境污(wu)染(ran)、降低作業(ye)噪音、增強設(she)備運(yun)行安全(quan)。據介紹,世界各大港(gang)(gang)口集(ji)裝(zhuang)(zhuang)箱(xiang)碼(ma)頭堆場作業(ye)通用(yong)的機(ji)械(xie)(簡稱(cheng)場橋)主(zhu)要有兩種:軌道式(shi)(shi)集(ji)裝(zhuang)(zhuang)箱(xiang)龍門起重機(ji)和輪(lun)胎式(shi)(shi)集(ji)裝(zhuang)(zhuang)箱(xiang)龍門起重機(ji),二者(zhe)各有優點。前者(zhe)用(yong)電網供電,節(jie)(jie)能,無噪音,無廢氣排放,

可(ke)靠(kao)性高,維修保養工作量小(xiao),致命的(de)(de)(de)缺點(dian)就是(shi)(shi)不能轉場(chang)(由一個箱(xiang)區轉移到另外一個箱(xiang)區)。因而世界在(zai)用(yong)的(de)(de)(de) 6500 臺(tai)場(chang)橋(堆場(chang)集裝箱(xiang)裝卸橋)95%是(shi)(shi)輪胎吊(diao),青島(dao)港也不例外。目前(qian),他們擁有此(ci)類機械 70 余臺(tai),2005 年總油耗達 700 萬升(sheng),占公司全部(bu)油耗的(de)(de)(de) 71%,是(shi)(shi)青島(dao)港出名(ming)的(de)(de)(de)耗油大戶(hu)。而輪胎吊(diao)“油改電(dian)”又是(shi)(shi)世界性的(de)(de)(de)難題(ti),沒有經驗可(ke)以借鑒。為(wei)數不少的(de)(de)(de)生產廠家和碼頭使用(yong)者都(dou)曾設想令(ling)軌道式集裝箱(xiang)起重機可(ke)以轉場(chang),但一直沒有實用(yong)的(de)(de)(de)產品(pin)問(wen)世。

   面(mian)對這一難題,許振超一直(zhi)在(zai)(zai)暗自(zi)琢磨,如何把兩種不同類型的(de)起重機的(de)優點結合起來(lai)。在(zai)(zai)公司(si)的(de)支(zhi)持下,他成(cheng)立了(le)“油(you)改電(dian)(dian)(dian)(dian)(dian)(dian)”專題攻關小(xiao)組(zu)(zu),經(jing)過一年多的(de)反復研究和方案論證,在(zai)(zai)國(guo)內外**提出了(le)移動滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)的(de)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)技術(shu)方案,即在(zai)(zai)集(ji)裝(zhuang)箱(xiang)堆(dui)場的(de)箱(xiang)區內,架設滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)路。當(dang)輪(lun)胎(tai)(tai)吊在(zai)(zai)箱(xiang)區作(zuo)業(ye)時,關閉柴(chai)油(you)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機組(zu)(zu),所需動力由專門設計的(de)集(ji)電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)置,將城(cheng)市用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)從滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)輸送到輪(lun)胎(tai)(tai)吊。輪(lun)胎(tai)(tai)吊沿滑(hua)(hua)(hua)觸(chu)(chu)線(xian)(xian)移動,實現對整(zheng)個箱(xiang)區的(de)工(gong)作(zuo)覆(fu)蓋。當(dang)輪(lun)胎(tai)(tai)吊需轉(zhuan)(zhuan)(zhuan)場到另一箱(xiang)區作(zuo)業(ye)時,則切斷電(dian)(dian)(dian)(dian)(dian)(dian)源與輪(lun)胎(tai)(tai)吊的(de)聯系(xi),改由柴(chai)油(you)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機組(zu)(zu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)并實現轉(zhuan)(zhuan)(zhuan)場。轉(zhuan)(zhuan)(zhuan)到指定堆(dui)場后,柴(chai)油(you)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機組(zu)(zu)停(ting)止工(gong)作(zuo),工(gong)動力重新切換(huan)為由市電(dian)(dian)(dian)(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。改造實現了(le)靈活(huo)變換(huan)堆(dui)場作(zuo)業(ye),又(you)消除了(le)原有的(de)重大缺(que)陷,**地(di)兼容(rong)了(le)軌道式(shi)和輪(lun)胎(tai)(tai)式(shi)集(ji)裝(zhuang)箱(xiang)龍門起重機的(de)優點,而且以(yi)投入(ru)技術(shu)改造費用(yong)低(di)、能耗低(di)、維(wei)修保養成(cheng)本低(di)及噪音小(xiao)、零排放展示(shi)出了(le)潛在(zai)(zai)的(de)巨大“含(han)金量”。

據(ju)實際運行測試,改造后的(de)輪(lun)(lun)胎吊能(neng)源成本由以前(qian)的(de)每(mei)作(zuo)業(ye)一(yi)個自然箱的(de) 5.9 元(yuan),直線下(xia)降至(zhi)2.3 元(yuan),能(neng)耗成本下(xia)降了(le) 60%以上。同(tong)時,還節省(sheng)了(le)原輪(lun)(lun)胎吊發動機每(mei)一(yi)萬小時就(jiu)(jiu)要(yao)(yao)進行 D 級保養、每(mei) 3-4 年就(jiu)(jiu)要(yao)(yao)進行大修(xiu),以及平時需(xu)(xu)專人(ren)維(wei)護(hu)等費用開(kai)支,平均每(mei)臺機械年節省(sheng)維(wei)修(xiu)成本至(zhi)少在 6.6萬元(yuan)以上。綜(zong)合這兩(liang)項,一(yi)臺輪(lun)(lun)胎吊此(ci)前(qian)完(wan)成一(yi)項作(zuo)業(ye)需(xu)(xu)花 100 元(yuan),油改電后僅(jin)(jin)需(xu)(xu) 40 元(yuan)錢(qian)就(jiu)(jiu)可完(wan)成。噪音也由原來輪(lun)(lun)胎吊 100 分貝左右(you)降到現(xian)在聽起(qi)來僅(jin)(jin)相當于一(yi)臺變頻空調工作(zuo)的(de)聲音,廢(fei)氣排放(fang)接近零(ling)。
