Umsele excavator: inkcazelo, izicelo, iifoto

ukumbiwa Indlu ezisetyenziswa imigodi (igrabile, udongwe, njl) ukususa nasemaweni. Kwakhona zisetyenziselwa iprofayili vee nelamaxandeka kaloliwe kunye nemijelo, kwakunye sindisa izinto loose kunye nenkunkuma rock. Le ndlela ingaphatha imihlaba ukuba udidi 4, musa ziqulathe amatye amakhulu (inclusions). Excavator isebenza kakuhle, ukuba ubukhulu be inclusions lingaphantsi kwe isahlulo sesihlanu ububanzi emele.

Kuyaphawuleka ukuba umphezulu ezantsi ngokusebenzisa indlela enjalo ifunyenwe tyaba kwaye akukho mfuneko kuyitshayela manual. Kweli nqaku siza kufunda ngakumbi oko okuthathwa excavator.

Okukodwa umsebenzi

Ngokuqhelekileyo, abembi multi-emele zisetyenziswa kwiindawo apho kukho umthamo omkhulu uhlobo olufanayo lomsebenzi, ugxininise indawo enye. Isizathu ilula - izixhobo zobukhulu ezinkulu. Ukuthutha ukusuka kwindawo ngeendawo ngenxa imisebenzi ezincinane ukuba imali eninzi nexesha, yaye ngoko, bekungalunganga. Ngokuba imisebenzi ezincinane, nto leyo ethetha intshukumo rhoqo, kukho umfuziselo encinane ngemoto okanye ivili womoya ukumbiwa.

Iintlobo multi-machine

Izixhobo ihlelwa ngeempawu ezifana:

• Bejonge intshukumo ngexesha lomsebenzi. Kusenokuba ukumbiwa longitudinal, ezinqamlezayo okanye umfuziselo ukumba rotary.
• Xa Uhlobo (ulwakhiwo) izixhobo zokusebenza. Kukho ukumbiwa chain nesondo-emele.
• Ngokutsho indlela kwezixhobo ngokunikezela ebusweni. ukusika rock i iphiramidi ebonisa nkqo, iphiramidi ebonisa tyaba okanye ngaxeshanye nkqo.

Ngokusekelwe kwezi mpawu, sinokugqiba ukuba kukho iintlobo ezininzi ukumbiwa. Makhe siqwalasele ngamnye kubo ngokwahlukeneyo.

umatshini cross-embe

Le ikhonkco excavator emele leyo zilandelwa okanye umkhondo kaloliwe. Powered by ukufana okanye ziqu amanxeba. I-chain ingabhekiswa ngqo (asetyenziswe kwimihlaba yohlobo olunye ukuze nezokukhupha kwezimbiwa okanye ubeko lamajelo ezinkulu vee) okanye ukuxhoma lathamba (esetyenziswa kwimihlaba kunye inclusions). Kukho kwakhona ukumbiwa, qha umgama leyo usenokwahluka ngokuxhomekeke kwiimeko yokusebenza. zisetyenziselwa umba nokucocwa kutsalwe kunye yokunkcenkceshela channels.

Technique ukumba longitudinal

Le emele umsele excavator. Ngokuqhelekileyo lo qha, ivili kunye qha, injini womoya okanye ukuthutha. Kwelinye icala, imodeli zokumba longitudinal yahlulwe kwabo asebenza kunye ikhonkco thunzi kunye nabo basebenza kungumzimba ivili ukhamba (ivili). Ezazisetyenziswa yokuqala imingxuma imingxuma ububanzi engadlulanga 1.1 m kunye nobunzulu 3.5 m Second Sinokuyiphanda umhadi nzulu -. 1.6-1.8 m.

rotary full-turn

Njengomgaqo, olu hlobo a qha. Kodwa maxa wambi kukho zikaloliwe. Ifowuni mayixhotyiswe ivili ibhakethi kunye injini yombane. Inokubuyiselwa zisikwe iliwa radially kwi iinqwelomoya tye kunye nkqo. It isetyenziselwa nezokukhupha kwezimbiwa ezithi zenzeke ngohlobo lamanqanaba. Kusenokuba udongwe eliyinjubaqa kunye nezinye izinto. Indlu excavator (emele) nayo kusetyenziswa ngemisebenzi ezinkulu zokwakha kunye ngumthwalo onzima.

Izinto eziluncedo ze multi-machine

Ngaphandle kwento yokuba nemihlakulwana zande kakhulu ngakumbi, multi-emele, abe kwiqela lokulungileyo engenakuphikwa ukuba bakwazi niqingqe wabo kwimarike. Makhe sihlolisise ezi mpawu:

• umsebenzi rhoqo kwi kumbiwa elulwalweni. Ngelo xesha, isixhobo single-emele ngexesha isampulu yomhlaba eqondile kutsho kuma-30% yexesha yokusebenza iyonke.
• Xa sithelekisa emele abangatshatanga kunye nemodeli multi-emele kunye nokusebenza enye, oko kunokubonwa ukuba imoto enye emele yesimathane inzima nengenakusebenziseka.
• Excavator ichitha cubic lokungahlangani 1 imitha zamatye amandla ngaphantsi kakhulu isixhobo kunye umthamo efanayo, kodwa ibhakethi elinye.

• Ukusebenza umsebenzi wokwakha, isixhobo multi-emele yenza Ukuxutywa efanayo zombini iintlobo eziphathekayo kunye nokulungisa zaveliswa.
• Ukuphuhlisa excavator umhlaba isingatha bevels. Ngenxa yoko, i-ngontsi ifumana iprofayili cross-somhlathi phantse abafezekileyo. umatshini emele-Omnye kukhulise kwemiqhele lekhefu yaye ngamnye kubo ushiye intsilelo.

nobubi zobuchwepheshe

Nangona kunjalo, kukho ubuninzi nemihlakulwana ngokucacileyo kweWCED. Mhlawumbi ngenxa yabo xesha njengenkokheli yoshishino. Excavator unabo ubuthathaka zilandelayo:

• Lo matshini - a foodie yokwenene, onako ukuphuhlisa umhlaba kuphela yohlobo olunye ngaphezulu akukho ngaphezu iklasi 4 okanye inclusions ezincinane iiklasi ukuya ku-3. Nefolokhwe akukho ngxaki ukuba ukusebenza kunye naluphi na udidi nohlobo lomhlaba, kuquka phezu emaweni.
• Umatshini ne-emele ayikho choosy kwisimo sezulu, ingeyo uguqulelo yebhakethi.

Kuba ukucaciselwa ukuhlalutya sibini umzekelo excavator.

EM-251

Le yunithi yasekhaya, equka:

• Udlula namandla zokusebenza, kwakunye neendlela ezithi zixhonywe isakhelo non-ejikelezayo ye yokuthutha ibhanti, nto leyo eyenzelwe ukuba bonakalise kwicala okanye emva kwezithuthi.
• izixhobo zokusebenza (chain kunye emele) ekhwele isakhelo-boom.

Njengoko izixhobo lesikhangela yenza multisupporting ezinqunquthayo. Injini yokuvutha kwangaphakathi amagiya zokuqhuba adlulisele ukujikeleza kusetyenziswa transmission chain. Track izakhelo ezidibene nge semiaxes kunye isixhobo elungelelanisayo kunye njengesakhelo esingundoqo. Kubonakala ukuba njengesakhelo esingundoqo lixhomekeke kwi qha kwiindawo ezintathu. Oku kwenza kube lula ukuphumeza i elungileyo cross-excavator.

Xa ukhamba chain excavator ngokwalo uhambisa, umsele nkqo yenziwe. Umhlaba lubuye emele, ngalo hopper lufika swa sona. Yena, ke, lilo eliya ngakuwe.

Multi-emele, umsele, imodeli chain EM-251 ungatshintsha indawo olusele kuthelekiswa kwisakhelo. Yena isiginci emva kwi-sikhokelo ukuba ikuvumela ukuba uguqule kancincane izinga elalana, yaye ngenxa yoko ke nobunzulu esemseleni wawakhotha. Xa ezithutha iyunithi boom oku obuphezulu. umatshini lilawulwa ulawulo ekhethekileyo ekude, nto leyo ifakwa elorini ungasekunene umqhubi, malunga gearshift. Oku kuvumela umqhubi esweni ngaxeshanye intshukumo umatshini kunye nomsebenzi ukumba iindlela.

EM-182

Makhe sihlolisise ezinye excavator emele omnye. Em-281 - njengoko ngamanye amaxesha ngempazamo ekubhekiselelwe kule modeli. Ifaka:

• Odnorebernymi undercarriage namavili. Kokuba imisiwe isakhelo detachable ukuxhasa hopper turasny counterweight isikhondo efama, ekharejini, ongentla isakhelo inxalenye ukhamba, yaye, ke, lo injini kunye ugqithiso.
• emazantsi ukhamba yesakhelo eye unit ezimbini yocwangciso ethwele chain kunye emele.
• Jib, leyo igcina inkqubo lamajelo kunye asithe nokumiswa.
• izixhobo zombane kunye nezixhobo izibane.

i excavator kulawulwa kwemigangatho ezintathu, apho zifumaneka cab somqhubi. Imvelaphi unoxanduva ekuguquleni i-chain ukhamba. Second - ngokuba ikhosi Sibona. Kakuhle kwaye eyesithathu - ngenxa yokukhuliswa, lisibekele le boom. Le yokugqibela igcinwe kwindawo efunekayo xa ubamba iziqhoboshi, apho ibekwe phezu kwizikhondo worm. I-injini yombane edlulisela isindululo ngokusebenzisa V-imixwayo, imeko apho, kwakunye diffraction engile le pulley eliqhutywa indawo tensioner. Shaft iphambili lidlulise ukujikeleza kusetyenziswa turasnomu chain drive. Le emele Umhlaba cut ikhutshelwa ukuya bese, uze emva koko ezinikwa Sibona, ezithutha yona kwindawo yayo engqongileyo.

Ngenxa excavator nokuphakamisa sokutsala into ngentambo, imifanekiso apho zinxulunyaniswe ngasentla kusetyenziswa ephezulu nesezantsi ngaxeshanye ukuze ukwemba synchronously waphakamisa kwaye kwehlisa apho zombini iziphelo ukhamba yesakhelo. Ngenxa yoko, lihamba isakhelo ukhamba zifana kuya ngokwayo. Emele apho umaleko kuba kude olulingana iyunifomu na ukuxhelwa ukuphakama. Ukuze afeze Fan ukusika, okuthetha intshukumo enye kuphela ekupheleni yesakhelo, oko uvikivwa ngokufanelekileyo.

isiphelo

Namhlanje siye safumanisa into okuthathwa ukumbiwa multi-emele yaye kutheni ayikho eqhelekileyo emele omnye. Kubalulekile ukuphawula ukuba izithintelo zokusebenza umthamo yeemoto ebekwe umbono lomhlaba, kunokuba eqhelekileyo yaye zahluke kwiintlobo ezahlukeneyo ukumbiwa. A ukuphucuka okuqhubekayo multi-oomatshini kunye nokuqaliswa lwezoyilo ezintsha icebisa ukuba kwixesha elifutshane zonke iziphene ziza kupheliswa

Ngendlela, ukuba excavator ngokuqhelekileyo kuquka ukumba eqhubekayo, nangona kuzo endaweni emele omzimba zokusebenza wokugaya okanye scrapers.
