鋼(gang)輪式壓路機小(xiao)常識
碾(nian)(nian)輪(lun)構造有光碾(nian)(nian)、槽碾(nian)(nian)和羊足碾(nian)(nian)等。光碾(nian)(nian)應用(yong)最普遍,鋼輪(lun)式壓(ya)(ya)(ya)路機主要用(yong)于路面(mian)面(mian)層(ceng)壓(ya)(ya)(ya)實。采用(yong)機械或液壓(ya)(ya)(ya)傳動,能集中(zhong)力(li)量(liang)壓(ya)(ya)(ya)實突起部(bu)分,壓(ya)(ya)(ya)實平整度高,適于瀝(li)青路面(mian)壓(ya)(ya)(ya)實作業(ye)。
鋼輪(lun)式壓路機(ji)按(an)輪(lun)軸(zhou)(zhou)布置有單(dan)軸(zhou)(zhou)單(dan)輪(lun)、雙(shuang)(shuang)軸(zhou)(zhou)雙(shuang)(shuang)輪(lun)、雙(shuang)(shuang)軸(zhou)(zhou)三(san)輪(lun)和(he)三(san)軸(zhou)(zhou)三(san)輪(lun)等(deng)種。
以內燃(ran)機為動(dong)(dong)力,采用(yong)機械傳動(dong)(dong)或液壓傳動(dong)(dong)。一般前(qian)輪轉向(xiang),機動(dong)(dong)性(xing)好,后輪驅(qu)動(dong)(dong)。為改善轉向(xiang)及碾壓性(xing)能,宜(yi)采用(yong)鉸接(jie)式轉向(xiang)結(jie)構和(he)全輪驅(qu)動(dong)(dong)。前(qian)輪框(kuang)架和(he)機架鉸接(jie),以減(jian)少路面不平時的機身(shen)擺動(dong)(dong)。后輪和(he)機架為剛性(xing)聯接(jie)。
鋼(gang)輪(lun)式壓(ya)路(lu)機采(cai)用液壓(ya)操縱、用液壓(ya)缸控制轉向。前(qian)后碾(nian)(nian)輪(lun)均裝有刮板(ban)以清除碾(nian)(nian)輪(lun)上粘結物。還裝有噴(pen)水系(xi)統,用于壓(ya)實瀝青(qing)路(lu)面時,對碾(nian)(nian)輪(lun)灑水以防(fang)瀝青(qing)混合料粘附。為增大(da)作用力還可(ke)在碾(nian)(nian)輪(lun)內加裝鐵、砂、水等加大(da)壓(ya)重。
鋼(gang)輪式(shi)壓(ya)(ya)路(lu)機(ji)(ji)(ji)(ji)的主要(yao)技術參數(shu)是(shi)機(ji)(ji)(ji)(ji)重(zhong)(zhong)和線壓(ya)(ya)力(li)。80年代各種鋼(gang)輪式(shi)壓(ya)(ya)路(lu)機(ji)(ji)(ji)(ji)機(ji)(ji)(ji)(ji)重(zhong)(zhong)范(fan)圍約為(wei):兩輪壓(ya)(ya)路(lu)機(ji)(ji)(ji)(ji)2~13噸(dun),三(san)輪壓(ya)(ya)路(lu)機(ji)(ji)(ji)(ji)1~15噸(dun),按需(xu)要(yao)可加(jia)壓(ya)(ya)重(zhong)(zhong)1~3噸(dun),三(san)軸三(san)輪壓(ya)(ya)路(lu)機(ji)(ji)(ji)(ji)13~14噸(dun),加(jia)壓(ya)(ya)重(zhong)(zhong)后為(wei)18~19噸(dun)。
