I-chassis engaphantsi kwekhareji enesixhobo esijikelezayololunye loyilo olungundoqo lwabembi ukufezekisa imisebenzi esebenzayo kunye neguquguqukayo. I-organically idibanisa isixhobo esisebenzayo esiphezulu (i-boom, intonga, ibhakethi, njl.) kunye nesixhobo sokuhamba esisezantsi (iingoma okanye amathayi) kwaye yenza ukujikeleza kwe-360 ° ngokusebenzisa i-slewing bearing kunye ne-drive system, ngaloo ndlela ukwandisa kakhulu uluhlu lokusebenza. Oku kulandelayo lucazululo oluneenkcukacha lwezicelo zayo ezithile kunye noncedo:
I. Ukwakhiwa koLwakhiwo lwe-Rotary undercarriage
1. Ukuthwala iRotary
- Ibhola enkulu okanye iibheringi ze-roller ezidibanisa isakhelo esiphezulu (inxalenye ejikelezayo) kunye nesakhelo esisezantsi (i-chassis), i-axial, i-radial forces, kunye nemizuzu yokubhukuqa.
- Iindidi eziqhelekileyo: umgca omnye-umgca we-4-point-point contact ball bearings (i-lightweight), ii-roller bearings ezinqamlekileyo (ezinzima-umsebenzi).
2. Inkqubo yeRotary Drive
-Injini yeHydraulic: iqhuba igiya ejikelezayo ngesixhobo sokunciphisa ukufezekisa ukujikeleza okugudileyo (isisombululo esiqhelekileyo).
- Imoto yombane: isetyenziswe kwi-excavators yombane, ukunciphisa ilahleko ye-hydraulic kunye nokubonelela ngokukhawuleza impendulo.
3. Uyilo lweUndercarriage olomeleziweyo
- Isakhiwo sensimbi esomeleziweyo se-undercarriage frame ukuqinisekisa ukuqina kwe-torsional kunye nokuzinza ngexesha lokubulala.
-Uhlobo lwetrekhi ephantsi kwekhareji idla ngokufuna igeyiji yomzila obanzi, ngelixa i-chassis yodidi lwetayara kufuneka ixhotyiswe nge-hydraulic outriggers ukulinganisa umzuzu wokuxhela.
II. Uphuculo olungundoqo kuMsebenzi we-Excavator
1. Ukuguquguquka kokuSebenza
- 360° Ukusebenza okungathintelekiyo: Akukho mfuneko yokushenxisa i-chassis ukuze igqume yonke indawo engqongileyo, ilungele izithuba ezimxinwa (ezifana nokwakhiwa kwedolophu, ukugrunjwa kwemibhobho).
- Ukuma okuchanekileyo: Ukulawulwa kwevalve ngokulinganayo kwisantya sokuxhwitha kwenza ukuba i-millimeter-level ibekwe kwindawo yebhakethi (njengokugqitywa komngxuma wesiseko).
2. UPhuculo lokuSebenza ngokuSebenzayo
- UkuNcitshiswa koMvezo wokuNyulwa: Abenzi bezixhobo zemveli ezisisigxina kufuneka bahlengahlengise rhoqo izikhundla, ngelixa i-rotary undercarriage chassis inokutshintsha ubuso bokusebenza ngokujikeleza, ukugcina ixesha.
-Iintshukumo eziDityanisiweyo eziDityanisiweyo: Ukuthoba kunye nokulawula unxibelelwano lwentonga (ezifana nezenzo "zokujingiwa") kuphucula ukusebenza kakuhle komjikelo.
3. Uzinzo kunye noKhuseleko
- Iziko loLawulo lweGravity: Imithwalo enamandla ngexesha lokuxhwila isasazwa nge-undercarriage, kwaye uyilo oluchasene nobunzima luthintela ukubhukuqa (njengama-counterweights afakwe ngasemva kwi-excavators yemigodi).
- Uyilo lwe-Anti-vibration: I-inertia ngexesha lokunyathela isiqhoboshi ikhuselwe yi-undercarriage, inciphisa impembelelo yesakhiwo.
4. Ukwandiswa kwemisebenzi emininzi
-Utshintsho olukhawulezayo lwe-Interfaces: I-chassis yokubulala ivumela ukutshintshwa ngokukhawuleza kwezinto eziqhotyoshelweyo ezahlukeneyo (ezifana neehamile ze-hydraulic, i-grabs, njl.), ukuziqhelanisa neemeko ezahlukeneyo.
- Ukudityaniswa kweZixhobo eziNcedisayo: Ezinje ngemigca yehydraulic ejikelezayo, iziqhoboshelo ezixhasayo ezifuna ukujikeleziswa okuqhubekayo (njengee-augers).
III. Iimeko zosetyenziso oluqhelekileyo
1. Iindawo zokwakha
-Ukugqiba imisebenzi emininzi njengokugrumba, ukulayisha, kunye nokulinganisa kwindawo encinci, ukunqanda ukuhamba rhoqo kwe-chassis kunye nokungqubana nemiqobo.
2. Ukwembiwa kwemigodi
- I-excavators ye-tonnage enkulu kunye ne-chassis ephezulu yamandla e-slewing ukumelana nokugrumba umthwalo onzima kunye nokujikeleza kwexesha elide eliqhubekayo.
3. Uhlangulo oluNgxamisekileyo
-Ukubulala ngokukhawuleza ukulungisa indlela yokusebenza, kudityaniswe nokubamba okanye ukucheba ukucoca inkunkuma.
4. EzoLimo naMahlathi
- Ikhareji yangaphantsi ejikelezayo iququzelela ukubamba kunye nokupakishwa kweenkuni okanye ukugrunjwa nzulu kwemingxuma yemithi.
IV. Iindlela zoPhuhliso lwezobuGcisa
1. Ulawulo lweRotary olukrelekrele
- Ukubeka iliso kwi-angle ye-rotary kunye nesantya nge-IMU (iYunithi yoMlinganiso we-Inertial), ukuthintela ngokuzenzekelayo izenzo ezinobungozi (ezifana nokubulala kumathambeka).
2. I-Hybrid Power Rotary System
- Iimoto ezijikelezayo zombane zibuyisela amandla okuqhobosha, ukunciphisa ukusetyenziswa kwamafutha (njengeKomatsu HB365 hybrid excavator).
3. Ibhalansi yokuKhanya kunye noKuhlala ixesha elide
- Ukusebenzisa intsimbi ephezulu okanye izinto ezidibeneyo zokunciphisa ubunzima be-undercarriage ngelixa ulungisa ukutywinwa kwe-rotary (ubungqina bothuli, ubungqina bamanzi).
V. Amanqaku eSondlo
- Ukuthanjiswa rhoqo kwebheringi ejikelezayo: Kunqanda ukunxitywa kwendlela yomdyarho ebangela ingxolo yangaphantsi kwekhareji okanye ukungcangcazela.
- Jonga ukulayishwa kwangaphambili kwebholithi: Ukukhulula iibholiti ezidibanisa ibhereyi yokubulala kunye ne-chassis kunokubangela ubungozi bolwakhiwo.
-Jonga ukucoceka kweoyile ye-hydraulic: Ukungcoliswa kunokukhokelela kumonakalo ojikelezayo wemoto kwaye kuchaphazele ukusebenza kwe-undercarriage drive.
Isishwankathelo
I-chassis engaphantsi kwekhareji enesixhobo esijikelezayo luyilo olwahlukileyo olwahlula abembi bezinto zakudala kwabanye oomatshini bokwakha. Ngokusebenzisa "i-undercarriage esisigxina kunye nomzimba ojikelezayo ojikelezayo", ifezekisa imo esebenzayo, eguquguqukayo kunye nekhuselekileyo yokusebenza. Kwixesha elizayo, ngokungena kombane kunye nobuchwephesha obukrelekrele, i-undercarriage ejikelezayo iya kuphuhlisa ngakumbi ukugcinwa kwamandla, ukuchaneka kunye nokuqina, ibe likhonkco elingundoqo ekuphuculweni kobuchwepheshe be-excavators.
