Ukwethulwa Kafushane Komshini Wekhanda Lomgwaqo

Umshini we-roadheader, ophinde ubizwe ngokuthi i-roadheader yohlobo lwe-boom, i-roadheader, noma umshini wesihloko, umshini wokumba. Iqala ukubonakala ngeminyaka yawo-1970 ngezicelo zezimayini. Umshini we-Roadheader unamakhanda okusika anamandla, ngakho ungowomhlaba wonke owezimayini zamalahle, izimayini zamaminerali angewona ezensimbi, kanye nomhubhe oyisicefe. Nakuba umshini we-roadheader mkhulu, usengakwazi ukuguquguquka phakathi nemihubhe yezokuthutha, ukuvuselelwa kwemihubhe ekhona, nokumbiwa kwemigede engaphansi.

Ihlanganisani?

Umshini we-roadheader uqukethe indlela yokuhamba ye-crawler, amakhanda okusika, ipuleti lefosholo, ingalo yokuqoqa impahla, kanye ne-conveyor.

Indlela yokuhamba iyasebenza ukuze iqhubekele phambili ngesiseshi. Ukusika amakhanda kwakuhlanganisa izinkinobho eziningi ze-tungsten carbide ezifakwe ngendlela ye-helical. Izinkinobho ze-Tungsten carbide, ezaziwa nangokuthi izinkinobho ze-carbide zikasimende noma amazinyo e-tungsten carbide, zinezakhiwo zobulukhuni kanye nokumelana nomthelela. Banomphumela omuhle ekusebenzeni komshini. Ipuleti lefosholo lisekhanda lomshini wesihloko somgwaqo osetshenziselwa ukusunduza ucezu ngemva kokusika. Khona-ke izingalo ezimbili zokuqoqa ama-loader, ziphenduka zibheke kolunye uhlangothi, zibuthe izingcezwana bese zizifaka ku-conveyor. I-conveyor nayo ingumshini wohlobo lwesiseshi. Ingakwazi ukudlulisa izingcezu kusukela ekhanda kuya ngemuva komshini we-roadheader.

Isebenza kanjani?

Ukuze uthole umhubhe oyisicefe, u-opharetha kufanele aqhube umshini ukuze uqhubekele endaweni yedwala futhi enze amakhanda okusika ajikeleze futhi asike amadwala. Ngokusikwa nokuthuthuka, izingcezu zamadwala ziyawa. Ipuleti lefosholo lingakwazi ukusunduza ucezu lwedwala, futhi izingalo eziqoqayo zezilayishi zizihlanganise ku-conveyor ukuze zihanjiswe ekupheleni komshini.

Izinhlobo ezimbili zokusika ikhanda

Kunezinhlobo ezimbili zokusika amakhanda i-roadheader engahlonyiswa ngazo. Eyodwa inhloko yokusika evundlile, enamakhanda okusika amabili amiswe ngokulinganayo futhi azungeza ngokuhambisana ne-axis ye-boom. Enye inhloko yokusika i-longitudinal, enekhanda elilodwa lokusika elilodwa kuphela futhi lizungeza i-perpendicular ku-axis ye-boom. Ngakho-ke ezimweni eziningi, isilinganiso samandla samakhanda okusika avundlayo siphezulu kunaleso samakhanda okusika ama-longitudinal.

Izinkinobho ze-Tungsten carbide emakhanda okusika

Ngesikhathi sokusika amatshe, ingxenye ebaluleke kakhulu izinkinobho ze-tungsten carbide ezifakwe emakhanda okusika. Izinkinobho ze-Tungsten carbide ziyizinto eziqinile futhi zinezinzuzo zezinga lokushisa eliphezulu, ingcindezi ephezulu, nokumelana nokugqoka. Izinkinobho ze-tungsten carbide zihlangana namazinyo omzimba ukuze zakhe i-shank bit eyindilinga. Ama-shank bits amaningana ayindilinga ashiselwe emakhanda okusika nge-engeli ethile.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
