Izici zokusebenza kwesakhiwo se-track undercarriage

I-crawler undercarriage icishe ihlukaniswe yaba izinhlobo ezimbili ngokuya ngento yesiseshi:

1. I-chassis yethrekhi yerabha;

2. I-chassis yensimbi yokukhasa.

imfuneko yamakhono

I-chassis yethrekhi yerabha yerabha ifaneleka kakhulu imboni encane yokukhanya kanye nemboni yemishini encane yokwakha.Imboni ekhanyayo ngokuvamile iyimishini yezolimo phakathi kwethani elilodwa kuya kwamathani amane.Imboni yemishini yokwakha isetshenziswa kakhulu embonini encane yokumba.

Ukukhethwa kwendawo yokusebenza kwayo cishe kungokulandelayo:

(1) Izinga lokushisa elisebenzayo lethrekhi yenjoloba ngokuvamile liphakathi kuka -25~+55′C.

(2) Usawoti wamakhemikhali, uwoyela namanzi olwandle uzosheshisa ukuguga kwethrekhi, ngakho ithrekhi kufanele ihlanzwe ngemva kokusetshenziswa endaweni enjalo.

(3) Indawo yomgwaqo enezingqimba ezicijile (njengezinsimbi zensimbi, amatshe, njll.) izobangela ukuhlukumezeka kwethrekhi yenjoloba.

(4) Imiphetho, ama-ruts noma indlela egandayiwe engalingani izobangela ukuqhekeka kwephethini ohlangothini oluphansi lonqenqema lwethrekhi, olungaqhubeka nokusetshenziswa lapho imifantu ingoni intambo yensimbi.

(5) Imigwaqo ewubhuqu namatshe izodala ukuguga ngaphambi kwesikhathi kwendawo yenjoloba lapho ihlangana nesondo elithwala umthwalo, yenze imifantu emincane.Ezimweni ezimbi kakhulu, ukungena kwamanzi kuzobangela ukuba i-iron ewumgogodla iwe futhi intambo yensimbi iphuke.

Isakhiwo kanye nokwakheka

Amagiya okugijima ama-Crawler asetshenziswa kakhulu emishinini yokwakha, ogandaganda nakwezinye izimoto zasensimini.Izimo zokugijima zinzima, futhi indlela yokugijima iyadingeka ukuze ibe namandla anele kanye nokuqina, kanye nekhono elihle lokuhamba nokuqondisa.

Ithrekhi ixhumene nomhlabathi, futhi isondo lokushayela alixhumani nomhlabathi.Lapho injini ishayela isondo lokushayela ukuze lijikeleze, isondo lokushayela lilokhu ligingqa ithrekhi ukusuka ngemuva ngokuhlanganyela phakathi kwamazinyo egiya esondo lokushayela kanye neketango lethrekhi ngaphansi kwesenzo setorque yokushayela yesinciphisi.

Ingxenye yethrekhi ethinta phansi inika umhlaba amandla okubuyela emuva, okwenza ithrekhi iphendule phambili, okungamandla ashayelayo aqhubekisela phambili umshini.

Lapho amandla okushayela anele ukunqoba ukumelana nokuhamba, ama-roller aqhubekela phambili endaweni engaphezulu yethrekhi, ukuze umshini uhambe phambili.Iziseshi zangaphambili nangemuva zendlela yokuhamba ye-crawler yawo wonke umshini zingaqondiswa ngokuzimela, ukuze i-radius ephendukayo ibe mancane.

Isisetshenziswa esihambayo sesiseshi siqukethe “amasondo amane nebhande elilodwa” (isondo lokushayela, irola, isondo lomhlahlandlela, isondo elidonsayo nesiseshi), idivayisi yokuqinisa amandla, isiphethu sebhafa, nendlela yokuhamba.Njengoba kuboniswe ngezansi.
