Crawler hydraulic excavator ndi makina oyendetsa dziko lapansi omwe amagwiritsa ntchito ndowa kuti afufuze zinthu pamwamba kapena pansi pazitsulo ndikuzikweza m'galimoto yonyamula katundu kapena kuzitsitsa kumalo osungirako katundu.Zida zofukulidwa makamaka ndi dothi, malasha, silt, nthaka ndi thanthwe pambuyo pomasulidwa.
Tikayang'ana pa chitukuko cha makina omanga m'zaka zaposachedwapa, chitukuko cha zofukula zimakhala mofulumira.Monga imodzi mwamakina ofunikira kwambiri pakumanga uinjiniya, kusankha kolondola kwa zokumba ndikofunikira kwambiri.Makina apadera ndi zida zomwe zimagwiritsidwa ntchito kwambiri pomanga migodi ndi m'matauni ndi kumidzi ndikuchita bwino komanso luso lapadera.
Dzina lachi China: Crawler hydraulic excavator
Dzina lachilendo: makina okumba
Ntchito: migodi ndi zomangamanga m'mizinda ndi kumidzi
Mawu Oyamba: Kukumba ndi kudzaza zinthu ndi ndowa
Patha zaka zoposa 130 kuchokera pamene chofukula choyamba chamanja chinatuluka.Panthawi imeneyi, yakhala ikukula pang'onopang'ono kuchokera ku zofukula za ndowa zoyendetsedwa ndi nthunzi kupita ku zofukula zamagetsi zoyendetsedwa ndi magetsi komanso zoyaka mkati mwa injini, komanso zofukula zodziwikiratu za hydraulic pogwiritsa ntchito electroencephalographic.kuphatikiza luso.ndondomeko.
Chifukwa cha kugwiritsa ntchito ukadaulo wa hydraulic, panali chofufutira chokwera chokhala ndi hydraulic backhoe pa thirakitala m'ma 1940.Kumayambiriro ndi pakati pa zaka za m'ma 1950, chofukula cha azimuth hydraulic hydraulic excavator ndi crawler full hydraulic excavator zidapangidwa motsatizana..
Woyamba wopangidwa ndi hydraulic excavator amatenga ukadaulo wa hydraulic wa zida za ndege ndi makina, alibe zida zama hydraulic zoyenera kugwirira ntchito mosiyanasiyana chofufutira, mawonekedwe opangira siwokhazikika mokwanira, ndipo zida zothandizira sizikwanira.
Kuyambira m'ma 1960, ofukula ma hydraulic alowa mu gawo lolimbikitsa komanso chitukuko champhamvu.Chiwerengero cha opanga zofukula ndi mitundu yosiyanasiyana m'maiko osiyanasiyana chawonjezeka kwambiri, ndipo zotulutsa zakwera kwambiri.
Kuchokera mu 1968 mpaka 1970, zofukula za hydraulic zidapanga 83% ya zofukula zonse, ndipo tsopano zayandikira 100%.
Chofukulacho chinali choyambirira pamanja, ndipo patha zaka zoposa 130 kuchokera pamene chinapangidwa, ndipo chakumana ndi njira zosiyanasiyana zoyendetsera galimoto monga steam drive, electric drive, and internal combustion engine drive.
Pambuyo pa zaka za m'ma 1940, teknoloji ya hydraulic inagwiritsidwa ntchito pofukula, ndipo m'zaka za m'ma 1950, zofukula zamtundu wamtundu wa hydraulic zomwe zimapezeka masiku ano zinapangidwa.
The magawo atatu zofunika kwambiri ofukula: galimoto kulemera (misa), injini mphamvu ndi ndowa mphamvu.
Mu 1951, backhoe yoyamba ya hydraulic backhoe idakhazikitsidwa ku McClainfakitale ku France, motero kulenga danga latsopano m'munda wa luso chitukuko ofukula ofukula.
kupanga
Mipangidwe yodziwika bwino yofukula mabwinja imaphatikizapo zida zamagetsi, zida zogwirira ntchito, njira zopha anthu, njira zowongolera, njira zotumizira, njira zoyenda ndi zida zothandizira.
Kuchokera pamawonekedwe, chofukulacho chimapangidwa ndi magawo atatu: chipangizo chogwirira ntchito, chosinthira chapamwamba ndi makina oyendayenda.
Gulu
Nawa gulu la ofukula wamba:
Gulu 1: Zofukula wamba zimagawidwa m'mitundu iwiri: zofukula zoyendetsedwa ndi injini zoyaka mkati ndi zofukula zoyendetsedwa ndi magetsi.Pakati pawo, zofukula zamagetsi zimagwiritsidwa ntchito makamaka m'mapiri a hypoxia, migodi yapansi panthaka ndi malo ena oyaka komanso ophulika.
Gulu 2: Malinga ndi njira zosiyanasiyana zoyendera, zofukula zimatha kugawidwa kukhala zofukula zokwawa komanso zofukula zamawilo.
Gulu 3: Malinga ndi njira zosiyanasiyana zotumizira, zofukula zimatha kugawidwa kukhala zofukula zama hydraulic ndi zofukula zamakina.Zofukula zamakina zimagwiritsidwa ntchito makamaka m'migodi ina yayikulu.
Gulu 4: Malinga ndi kugwiritsidwa ntchito, ofukula amatha kugawidwa kukhala ofukula wamba, ofukula migodi, ofukula m'madzi, ofukula apadera ndi magulu ena osiyanasiyana.
Zofukula zambiri zamasiku ano ndizofukula za hydraulic azimuth.Caterpillar 385B Excavator
Zofukula za hydraulic zimapangidwa makamaka ndi injini, makina a hydraulic, zida zogwirira ntchito, zida zoyendera ndi kuwongolera magetsi.Dongosolo la hydraulic lili ndi pampu ya hydraulic, valve control, hydraulic cylinder, hydraulic motor, pipeline, tank mafuta, ndi zina zotero.
Malinga ndi kapangidwe kake ndi kagwiritsidwe ntchito kake, zitha kugawidwa m'magulu otsatirawa:
Mtundu wa Crawler, mtundu wa tayala, mtundu woyenda, hydraulic wathunthu, semi-hydraulic, azimuth, non-azimuth, general, special, articulated, telescopic boom ndi mitundu ina.
Chipangizo chogwirira ntchito ndi chipangizo chomwe chimamaliza mwachindunji ntchito yofukula.Zimapangidwa ndi zigawo zitatu: boom, ndodo ndi ndowa.Kukweza kwa Boom, kukulitsa ndodo ndi kuzungulira kwa ndowa kumayendetsedwa ndi kubwereza ma silinda a hydraulic ochita kawiri.
Pofuna kukwaniritsa zofunikira pa ntchito zosiyanasiyana zomanga, ofukula ma hydraulic amatha kukhala ndi zida zosiyanasiyana zogwirira ntchito, monga kukumba, kukweza, kukweza, kukweza, kuwongolera, zingwe, bulldozing, nyundo zamphamvu ndi zida zina zogwirira ntchito.
Chipangizo chowombera ndi kuyenda ndi thupi la hydraulic excavator, ndipo gawo lapamwamba la turntable limaperekedwa ndi chipangizo chamagetsi ndi njira yotumizira.Injini ndiye gwero lamphamvu la hydraulic excavator, yomwe ambiri amagwiritsa ntchito mafuta a dizilo pamalo abwino, komanso amatha kugwiritsa ntchito mota yamagetsi m'malo mwake.
Ma hydraulic transmission system amatumiza mphamvu ya injini kupita ku hydraulic motor, hydraulic cylinder ndi ma actuators ena kudzera papampu ya hydraulic, ndikukankhira chipangizo chogwirira ntchito kuti chisunthe, potero kumaliza ntchito zosiyanasiyana.
