Izinduku Zokubhoboza Eziqoshiwe

Imishini yokubhoboza ene-tapered iphinde inikeze isigaba se-chuck esiyi-hexagonal ukuze inikeze amandla okuzungeza i-chuck bushing, ngokuvamile ephinde ibe nekhola engumgunyathi ukuze igcine isimo esifanelekile sobuso be-shank ku-rock drill, futhi ifanise i-tapered bit ekugcineni kwesokhethi. Izimbobo zivame ukubhobozwa ngamamitha angu-0.6 ukuze kufakwe ubude bokuphakela kwemilenze yomoya. Ngokungena okuphakeme, izimbobo eziqondile, impilo yesevisi ende kanye nezindleko eziphansi imitha ngayinye ebhoboziwe kunensimbi ehlanganisiwe, okokusebenza kokumba okune-tapered kubamba isabelo semakethe kusuka kunsimbi yokumba ehlangene, ikakhulukazi ekusetshenzisweni kwezimayini nasembonini yamatshe enobukhulu.
Ukwakheka kwamatshe okuhlukile kanye nokubhola kwamadwala kudinga ama-engeli ahlukene e-taper. Uma ubhoboza amatshe anamandla amakhulu okubhoboza i-hydraulic rock formations yamatshe aqinile kuya kokuqina futhi abrasive, i-taper angle ebanzi ivamise ukusetshenziswa. Ama-engeli e-taper angu-11° kanye no-12° ngokuvamile asetshenziswa kuma-drill rigs esimanje. Ukuze uthole ama-rock drill anomthelela ophansi kanye nokwakheka kwamatshe athambile, kusetshenziswa i-engeli encane ye-taper engu-7°. I-engeli engu-7° ingasetshenziswa futhi uma i-bit spinning iyinkinga uma kusetshenziswa okokusebenza okungu-11° no-12°. Ukwengeza, i-engeli engu-4.8°(nayo engu-4°46’) ilungele idwala elithambile uma usebenzisa ama-drill drill womoya noma osebenza ngogesi - ukuvimbela izingcezu ukuthi zingapholi noma zihlukaniseke. Induku eyodwa isetshenziselwa ukubhoboza izimbobo ezimfushane (≤2.0m), kuyilapho izinduku ochungechungeni zisetshenziselwa ukubhoboza izimbobo ezijulile (kufika ku-2.0m), ukugwema ukugoba kwengcindezi ngokweqile.
I-Plato tapered drill rods iza namabanga amathathu, futhi ubude butholakala ukusuka ku-600mm (2’) kuya ku-11,200mm (36’8”), (akalwa ukusuka kukhola kuya ekugcineni ocijile).
Ithebula Elinconyiwe Lamabanga Ama-Taper Rods:
| Amabanga | Izinhlobo | Izimo ezinconyiwe |
| Okuphakeme | G III, T III, | 1) Amandla athinta ama-rock drill: ≥76J, ngokuvamile imodeli: YT28 2) Ukujula kokumba: ≥ 2.5 m (8’ 2 27/64”) 3) Ukwakheka kwamadwala: idwala eliqinile, eliqinile, eliqinile eliphakathi nelithambile I-Protodyakonov Isikali Sokuqina: f ≥ 15 I-Uniaxial Compressive Strength: ≥150 Mpa 4) Ukushintshwa: G rod, G I rod, ROK |
| Okuvamile | G I, ROK | 1) Amandla athinta ama-rock drills: ＜ 76 J, ngokuvamile imodeli: YT24 2) Ukujula kokumba: ≤2.5 m (8’ 2 27/64”) 3) Ukwakheka kwamadwala: Itshe eliqinile elimaphakathi nelithambile I-Protodyakonov Ukuqina Isikali: f ＜15 I-Uniaxial Compressive Strength: ＜150 Mpa 4) Ukushintshwa: G rod |
| Umnotho | G | 1) Amandla athinta ama-rock drills: ＜ 76 J, ngokuvamile imodeli: YT24 2) Ukujula kokumba: ≤2.5 m (8’ 2 27/64”) 3) Ukwakheka kwamadwala: Itshe eliqinile elimaphakathi nelithambile I-Protodyakonov Ukuqina Isikali: f ＜10 I-Uniaxial Compressive Strength: ＜100 Mpa |
Uhlolojikelele lwezicaciso:
| Ubude Induku | I-Taper Degree | ||
| Isitayela seShank | mm | unyawo/intshi | |
| Hex22 × 108mm | 500 ~ 8,000 | 1’ 8” ~ 26’ 2” | 7°, 11° and 12° |
| Hex25 × 108mm | 1500 ~ 4,000 | 4’11” ~ 13’1” | 7° |
| Hex25 ×159mm | 1830 ~ 6,100 | 6’ ~ 20” | 7° kanye no-12° |
Amanothi:
1.Idigri ye-taper yokuxhumana evamile ngu-7°, 11° no-12°, amanye amadigri afana no-4.8°, 6° no-9° nawo ayatholakala uma ecelwa;
2.I-shank evamile yi-Hex22 × 108mm, Hex25 × 159mm nezinye izitayela nazo ziyatholakala uma ngesicelo samakhasimende;
3.Ubude benduku kufanele bucaciswe ngokulandelana;
4.Ukuze uvumelane nezimo ezihlukahlukene zamadwala, i-drill rod ikhethwa ngabasebenzisi.
