A crawler hydraulic excavator muchina unofamba nevhu unoshandisa bhaketi kuchera zvinhu pamusoro kana pazasi penzvimbo inotakura uye kuiisa mumotokari yekutakura kana kuiburitsa kune stockyard.Zvinhu zvakacherwa zvakanyanya ivhu, marasha, silt, ivhu uye dombo mushure me pr-loosening.
Tichitarisa kubva mukugadzirwa kwemichina yekuvaka mumakore achangopfuura, kugadzirwa kwevacheri kunokurumidza.Seimwe yeakanyanya kukosha ekuvaka muchina modhi mukuvaka kweinjiniya, kusarudzwa kwakaringana kwevanochera kunonyanya kukosha.Michina yakakosha nemidziyo inoshandiswa zvakanyanya mumigodhi nekuvakwa kwemadhorobha nekumaruwa nekuita kwepamusoro uye yakasarudzika tekinoroji.
Zita rechiChinese: Crawler hydraulic excavator
Zita rekunze: michina yekuchera
Zvishandiso: migodhi uye kuvaka kwemaguta uye kumaruwa
Nhanganyaya: Kuchera nekuzadza zvinhu nemugomo
Pave nemakore anopfuura 130 kubvira pakabuda bhuku rekutanga rekuchera.Munguva iyi, yakaona kuvandudzwa zvishoma nezvishoma kubva kumagetsi anotyairwa nemhepo uye mukati-anopisa-injini-inotyairwa einjini yekuchera, uye zvizere otomatiki hydraulic machera achishandisa electroencephalographic.yekubatanidza tekinoroji.process.
Nekuda kwekushandiswa kwe hydraulic tekinoroji, pakanga paine chicherwa chakaiswa chakashongedzerwa nehydraulic backhoe patirakita muma1940.Mukutanga uye pakati pe-1950s, azimuth hydraulic excavator uye inokambaira yakazara hydraulic excavator yakagadzirwa zvakatevedzana..
Muyedzo wekutanga-yakagadzirwa hydraulic excavator inotora hydraulic tekinoroji yendege nemichina yemidziyo, inoshaya ma hydraulic components akakodzera kune akasiyana siyana ekushanda mamiriro emucheri, mhando yekugadzira haina kugadzikana zvakakwana, uye zvikamu zvinotsigira hazvina kukwana.
Kubva kuma1960s, hydraulic excavators vakapinda mudanho rekusimudzira uye kusimudzira kwakasimba.Huwandu hwevagadziri vezvicherwa uye mhando munyika dzakasiyana-siyana hwakawedzera nekukurumidza, uye kubuda kwacho kwakawedzera.
Kubva muna 1968 kusvika muna 1970, kubudiswa kwema hydraulic excavators kwakaverengera 83% yehuwandu hwekuchera, uye ikozvino yava pedyo ne100%.
Iyo yekuchera yaimbove yemanyorero, uye yave nemakore anopfuura zana nemakumi matatu kubva pakugadzirwa kwayo, uye yakawana nzira dzekutyaira dzakasiyana siyana senge steam drive, electric drive, uye yemukati combustion engine drive.
Mushure memakore ekuma1940, hydraulic tekinoroji yakashandiswa kune vanochera, uye muma1950, iyo crawler-mhando yakazara-hydraulic yekuchera iyo yakajairika nhasi yakagadzirwa.
Iwo matatu akakosha maparamita ekuchera: uremu hwemotokari (misa), simba reinjini uye bhaketi kugona.
Muna 1951, yekutanga yakazara hydraulic backhoe yakatangwa paMcClainfekitari muFrance, nokudaro kugadzira nzvimbo itsva mumunda wehunyanzvi hwekuvandudza kwevacheri.
constitute
Mamiriro ezvinhu akajairika ekuchera anosanganisira masimba emagetsi, zvishandiso zvekushanda, nzira dzekuuraya, nzira dzekugadzirisa, nzira dzekutumira, nzira dzekufamba uye zvivako zvekubatsira.
Kubva pakuonekwa, mucherechedzo unoumbwa nezvikamu zvitatu: chishandiso chekushanda, chepamusoro turntable uye chifambiso chekufamba.
Classification
Izvi zvinotevera kupatsanurwa kwezvakajairwa machera:
Category 1: Kuchera kwakajairika kwakakamurwa kuita mhando mbiri: mukati memoto injini-inofambiswa machera uye magetsi anofambiswa nemagetsi.Pakati pavo, magetsi emagetsi anonyanya kushandiswa muplateau hypoxia, migodhi yepasi uye dzimwe nzvimbo dzinopisa uye dzinoputika.
Chikamu chechipiri: Zvinoenderana nemaitiro akasiyana ekufamba, vanochera vanogona kupatsanurwa kuva vanochera vanochera uye vanochera mavhiri.
Chikamu 3: Zvinoenderana neakasiyana nzira dzekufambisa, vanochera vanogona kupatsanurwa kuita hydraulic excavator uye mechanic excavator.Mechanical excavator inonyanya kushandiswa mune mimwe migodhi mikuru.
Chikamu chechina: Zvinoenderana nekushandiswa, vanochera vanogona kupatsanurwa kuva vanzveri vemazuva ese, vacheri vemigodhi, vanochera mugungwa, vakachera vakasarudzika uye mamwe mapoka akasiyana.
Ruzhinji rwevacheri vemazuva ano vakazara hydraulic azimuth yekuchera.Caterpillar 385B Excavator
Hydraulic excavator inonyanya kuumbwa neinjini, hydraulic system, chishandiso chekushanda, mudziyo wekufambisa uye kutonga kwemagetsi.Iyo hydraulic system inosanganisira hydraulic pump, control valve, hydraulic cylinder, hydraulic motor, pipeline, mafuta tank, etc. Iyo magetsi ekugadzirisa magetsi anosanganisira monitoring panel, injini control system, pump control system, sensors dzakasiyana-siyana, solenoid valves, nezvimwewo.
Zvinoenderana nechimiro uye kushandiswa kwayo, inogona kukamurwa kuita:
Crawler type, tire type, yekufamba, full hydraulic, semi-hydraulic, azimuth, non-azimuth, general, special, articulated, telescopic boom nemamwe marudzi.
Chishandiso chekushanda ndicho chigadziro chinopedzisa zvakananga basa rekuchera.Inosungirirwa kubva pazvikamu zvitatu: boom, tsvimbo uye bhakiti.Boom lift, kukwidziridzwa kwetsvimbo uye kutenderera kwebhaketi zvinodzorwa nekudzokorora kaviri-kuita hydraulic silinda.
Kuti zvizadzise zvinodikanwa zveakasiyana mashandiro ekuvaka, ma hydraulic excavator anogona kuve akashongedzerwa neakasiyana emidziyo yekushanda, senge kuchera, kusimudza, kurodha, kuenzanisa, zvisungo, bulldozing, sando dzekukanganisa uye mamwe maturusi ekushanda.
Mushonga wekuuraya uye wekufamba ndiwo muviri we hydraulic excavator, uye chikamu chepamusoro cheturntable chinopiwa nemagetsi emagetsi uye nzira yekufambisa.Injini ndiyo sosi yemagetsi e hydraulic excavator, mazhinji ayo anoshandisa mafuta edhiziri munzvimbo iri nyore, uye anogona zvakare kushandisa mota yemagetsi pachinzvimbo.
Iyo hydraulic transmission system inoendesa simba reinjini kune hydraulic mota, hydraulic cylinder uye mamwe ma actuators kuburikidza ne hydraulic pump, uye inosundira chishandiso chinoshanda kuti chifambe, nekudaro ichipedzisa mabasa akasiyana.
