Chigadziko chepasi pemotokari chine mudziyo unotendererandeimwe yemagadzirirwo makuru evacheri kuti vashande zvakanaka uye zvinochinjika. Inobatanidza mudziyo wepamusoro unoshanda (boom, stick, bucket, nezvimwewo) nehurongwa hwepasi hwekufamba (tracks kana matai) uye inobvumira kutenderera kwe360° kuburikidza neslewing bearing and drive system, nokudaro ichikura zvakanyanya nzvimbo yekushanda. Inotevera ongororo yakadzama yemashandisirwo ayo chaiwo uye zvakanakira:
I. Kuumbwa kweChigaro chepasi peRotary
1. Kutakura kweRotary
- Mabheya makuru ebhora kana kuti mabheya anotenderera anobatanidza furemu yepamusoro (chikamu chinotenderera) nefuremu yepasi (chassis), ine axial, radial forces, uye nguva dzekupidigura.
- Mhando dzakajairika: mabheyaringi ebhora ane mutsetse mumwe chete ane point ina (akareruka), mabheyaringi ane roller akayambuka (anorema).
2. Sisitimu yeRotary Drive
- Mota yeHydraulic: inotyaira giya re rotary bearing nepakati pe reducer kuti ikwanise kutenderera zvakanaka (mhinduro huru).
- Mota yemagetsi: inoshandiswa mumagetsi anochera, ichideredza kurasikirwa kwemvura uye ichipa mhinduro nekukurumidza.
3. Dhizaini Yezvigaro Zvepasi Petsoka Zvakasimbiswa
- Furemu yesimbi yakasimbiswa kuti ive nechokwadi chekuomarara uye kugadzikana panguva yekusveta.
- Chitima chepasi cherudzi rwetrack chinowanzoda gauge yakakura yetrack, nepo chassis yerudzi rwetairi ichida kuiswa ma hydraulic outriggers kuti aenzane nenguva yekuslewing.
II. Kuvandudzwa Kukuru Pakushanda Kwemucheri
1. Kuchinjika Kwekushanda
- 360° Kushanda Pasina Kuvharwa: Hapana chikonzero chekufambisa chassis kuti ifukidze nzvimbo dzese dzakapoteredza, yakakodzera nzvimbo dzakamanikana (dzakadai sekuvakwa kwemaguta, kucherwa kwemapaipi).
- Kuisa Nzvimbo Yakarurama: Kudzora kumhanya kwe slewing ne valvu inoenzana kunoita kuti bhaketi riiswe panzvimbo ine millimeter (sekupedzisa foundation pit).
2. Kugadzirisa Kushanda Nesimba Kwebasa
- Kufamba Kwakaderera: Ma excavator echinyakare anofanirwa kugadzirisa nzvimbo nguva nenguva, nepo chassis inotenderera pasi pemotokari inogona kuchinja mafaces ekushanda nekutenderera, zvichichengetedza nguva.
- Maitiro Akasanganiswa Akabatana: Kudzora kubatana kweSlewing ne boom/stick (sekuita "swinging") kunosimudzira kushanda zvakanaka kwecycle.
3. Kugadzikana uye Kuchengetedzwa
- Nzvimbo Yekutarisira Simba Rekukwevera Zvinhu Pasi: Mitoro inoshanduka panguva yekusveta inoparadzirwa kuburikidza nepasi pechingoro, uye dhizaini yehuremu hunodzivisa kupidiguka (senge zvinorema zvinosungirirwa kumashure pamichina yekuchera migodhi).
- Dhizaini yekudzivirira kudedera: Kusasimba panguva yekusveta mabhureki kunodzivirirwa nepasi pechitsiko, zvichideredza kukanganiswa kwechimiro.
4. Kuwedzera Kwemabasa Akawanda
- MaInterfaces ekuchinja nekukurumidza: Chigadziko chekusveta chinobvumira kukurumidza kutsiviwa kwezvinhu zvakasiyana-siyana (zvakaita senyundo dzehydraulic, ma grabs, nezvimwewo), zvichichinjika zvichienderana nemamiriro akasiyana-siyana.
- Kubatanidzwa kweMidziyo Yekubatsira: Zvakadai semitsetse ye hydraulic inotenderera, zvinotsigira zvinosungirirwa zvinoda kutenderera nguva dzose (senge ma auger).
III. Maitiro Akajairika Ekushandisa
1. Nzvimbo dzekuvaka
- Kupedza mabasa akawanda akadai sekuchera, kurodha, uye kuyera munzvimbo diki, kudzivirira kufamba-famba kwechisikigo kakawanda uye kuroverana nezvipingamupinyi.
2. Kuchera migodhi
- Michina yekuchera ine matani makuru ine chassis yakasimba yekuchera kuti ikwanise kutsungirira kucherwa kunorema uye kutenderera kwenguva refu.
3. Kununura Vanhu Panjodzi
- Kucheka nekukurumidza kugadzirisa divi rekushanda, pamwe chete nekubata kana kutema kuti ubvise marara.
4. Kurima neMasango
- Chigaro chepasi pevhu chinotenderera chinobatsira kubata nekurongedza huni kana kuchera makomba emiti zvakadzama.
IV. Maitiro Ekuvandudza Tekinoroji
1. Kudzora Kutenderera Kwakangwara
- Kutarisa kona inotenderera uye kumhanya kuburikidza neIMU (Inertial Measurement Unit), zvichizvidzora otomatiki zviito zvine njodzi (sekubaya sleeve pamawere).
2. Sisitimu yeHybrid Power Rotary System
- Mota dzemagetsi dzinotenderera dzinodzoreredza simba remabhureki, zvichideredza kushandiswa kwemafuta (senge Komatsu HB365 hybrid excavator).
3. Kuenzana kwehuremu hwakareruka uye kugara kwenguva refu
- Kushandisa simbi yakasimba kana zvinhu zvakasanganiswa kuderedza huremu hwepasi pemotokari uku uchigadzirisa kuvharwa kwemabheya anotenderera (anodzivirira guruva, asingapindi mvura).
V. Nzvimbo dzekugadzirisa
- Kuzorwa mafuta nguva dzose kwebearing rinotenderera: Kunodzivirira kusakara kwenzira yemujaho zvichikonzera ruzha kana kuzununguka kwepasi pechingoro.
- Tarisa kuti bhoti rakaiswa sei: Kusunungura mabhaudhi anobatanidza slewing bearing nechassis kunogona kukonzera njodzi dzekuvaka.
- Tarisa kuchena kwemafuta e hydraulic: Kusvibiswa kunogona kukonzera kukuvara kwemota inotenderera uye kukanganisa mashandiro ekutyaira pasi pechingoro.
Pfupiso
Chigadziko chepasi pemotokari chine nzira inotenderera dhizaini yakasiyana inosiyanisa ma excavator nemamwe michina yekuvaka. Kuburikidza ne "fixed undercariage uye rotating upper body", inoita kuti ishande zvakanaka, inochinjika uye yakachengeteka. Mune ramangwana, nekupinda kwemagetsi uye matekinoroji akangwara, chigadziko chepasi pemotokari chinotenderera chichaenderera mberi nekuchengetedza simba, kunyatsoita basa uye kugara kwenguva refu, chichiva chinhu chikuru mukuvandudzwa kwetekinoroji yema excavator.
