步履式挖掘機的組成結構
步(bu)履式挖(wa)(wa)掘機是(shi)一種(zhong)全地(di)型(xing)多(duo)功(gong)能(neng)挖(wa)(wa)掘機和(he)(he)多(duo)工(gong)具,多(duo)功(gong)能(neng)平臺。它由工(gong)作(zuo)裝置(zhi)(zhi)、行走裝置(zhi)(zhi)、上(shang)(shang)車、下車、回轉機構和(he)(he)液壓系統等等組成,采用(yong)四(si)個支腳(還可以帶行走輪(lun))支撐整機,四(si)個支腳用(yong)四(si)個液壓缸(gang)單獨操作(zuo),四(si)個支腳長度和(he)(he)支撐位(wei)置(zhi)(zhi)可在(zai)縱向、橫(heng)向和(he)(he)垂(chui)直三個方向調節,使挖(wa)(wa)掘機的(de)適用(yong)性和(he)(he)穩定性大大提(ti)高(gao),非常適合在(zai)凹凸不平和(he)(he)狹(xia)小(xiao)的(de)場地(di)上(shang)(shang)挖(wa)(wa)掘作(zuo)業。
行走裝置就(jiu)是底盤(pan)(pan),步履(lv)式挖掘(jue)機的(de)底盤(pan)(pan)是由多向接頭(tou),轉(zhuan)向液壓支腿,轉(zhuan)向裝置,液壓驅(qu)動(dong)(dong)馬(ma)達,輪胎(tai)組成(cheng),其功(gong)能(neng)為支承(cheng)挖掘(jue)機的(de)重量,并把液壓驅(qu)動(dong)(dong)馬(ma)達傳遞的(de)動(dong)(dong)力轉(zhuan)變為牽引力,實現整機的(de)行走。
工(gong)作裝(zhuang)(zhuang)置是(shi)步履式挖(wa)掘(jue)機的主要(yao)組(zu)成(cheng)部分(fen),通常(chang)包(bao)括箱型伸縮斗桿挖(wa)掘(jue)臂(bei),駕駛(shi)室,360度回轉平臺。工(gong)作裝(zhuang)(zhuang)置除(chu)了可(ke)(ke)以挖(wa)坑、開溝(gou)、裝(zhuang)(zhuang)載外,還(huan)可(ke)(ke)以進(jin)行簡單平整場地工(gong)作。
步履式挖掘機有什么特點
步(bu)履式挖(wa)掘機(ji)是(shi)新(xin)一(yi)代智能(neng)產品(pin),跋山(shan)涉水如履平地(di),靈活機(ji)動(dong)操(cao)控(kong)自如,是(shi)一(yi)種(zhong)可在(zai)(zai)高原,平原地(di)區使用(yong)(yong)的挖(wa)掘機(ji),能(neng)適(shi)應各(ge)種(zhong)地(di)形(xing)。步(bu)履式挖(wa)掘機(ji)采用(yong)(yong)步(bu)履,輪(lun)式驅動(dong)結(jie)合(he)的方式,能(neng)全(quan)(quan)輪(lun)驅動(dong),全(quan)(quan)輪(lun)轉向,輪(lun)腿(tui)復合(he)。它(ta)不僅(jin)在(zai)(zai)外觀上具(ju)有強烈的震(zhen)撼(han)感,而且(qie)科技(ji)含量高,突(tu)破了傳統(tong)工程機(ji)械(xie)的發展模式,
步履式(shi)挖(wa)掘(jue)(jue)機工(gong)(gong)作形(xing)式(shi)與傳統履帶式(shi)挖(wa)掘(jue)(jue)機的(de)(de)大(da)(da)(da)致相同,主要區別是底盤(pan)行(xing)(xing)走部分。它(ta)克服了傳統履帶式(shi)挖(wa)掘(jue)(jue)機不能(neng)在復雜地(di)形(xing)工(gong)(gong)作的(de)(de)缺點,譬如在大(da)(da)(da)角度山(shan)地(di),較高垂直障礙(ai)物(wu),河(he)流,沼(zhao)澤(ze),雪(xue)山(shan),鐵路軌(gui)道行(xing)(xing)駛等(deng)。利(li)用(yong)獨(du)立(li)多自(zi)由(you)度轉(zhuan)向(xiang)液(ye)(ye)(ye)壓(ya)(ya)支(zhi)腿進行(xing)(xing)自(zi)由(you)角度調整,補償地(di)形(xing)凸凹(ao)高度差(cha),實現在大(da)(da)(da)角度傾斜地(di)形(xing)行(xing)(xing)駛,行(xing)(xing)走,施(shi)工(gong)(gong)的(de)(de)目的(de)(de)。利(li)用(yong)箱型(xing)伸縮斗桿挖(wa)掘(jue)(jue)臂與獨(du)立(li)多自(zi)由(you)度轉(zhuan)向(xiang)液(ye)(ye)(ye)壓(ya)(ya)支(zhi)腿的(de)(de)配(pei)合作業(ye),能(neng)攀登,翻越數(shu)米(mi)的(de)(de)垂直障礙(ai)物(wu),在河(he)流,沼(zhao)澤(ze)行(xing)(xing)走,作業(ye)。配(pei)置液(ye)(ye)(ye)壓(ya)(ya)鋼絲(si)繩(sheng)卷揚器,在大(da)(da)(da)角度山(shan)地(di)(地(di)質較大(da)(da)(da)疏松)作業(ye),作業(ye)時(shi)(shi)將鋼絲(si)繩(sheng)固定,液(ye)(ye)(ye)壓(ya)(ya)支(zhi)撐爪固定地(di)面,起(qi)到(dao)安(an)全作業(ye)效果;還可以配(pei)備液(ye)(ye)(ye)壓(ya)(ya)馬達驅動,實現短(duan)距(ju)離獨(du)立(li)轉(zhuan)場,配(pei)置快(kuai)換(huan)接頭,可安(an)裝(zhuang)液(ye)(ye)(ye)壓(ya)(ya)打(da)孔裝(zhuang)置,液(ye)(ye)(ye)壓(ya)(ya)破碎錘,抓斗,液(ye)(ye)(ye)壓(ya)(ya)剪,打(da)樁機,小型(xing)掘(jue)(jue)進頭,形(xing)成(cheng)多功能(neng)平臺。當長距(ju)離轉(zhuan)場移動時(shi)(shi),挖(wa)掘(jue)(jue)機不需任何起(qi)吊設(she)備,可自(zi)行(xing)(xing)爬上、爬下運輸車輛(liang),轉(zhuan)移施(shi)工(gong)(gong)現場特別方(fang)便,轉(zhuan)場費用(yong)低。
