Isimiso sokusebenza kanye nendlela yokusebenza ye-overshot yewindi

1. Ukwakheka kwesithombe esingaphezu kwefasitela

I-overshot yewindi ishiselwe izingxenye ezimbili zomzimba wesilinda kanye nelunga elingaphezulu (futhi uxhumano olunentambo)

Ngokwezidingo zokuhlenga, indawo engezansi yesilinda ingenziwa ibe yizakhiwo ezine ezilandelayo:

(1) I-spiral semi-oblique cut kulula ukuyishintsha futhi yethule izinhlanzi.

(2) I-zigzag milling shoe cut ilungele ukusetha ukugaya ukuhlanza izinto eziqinile phezulu kwenhlanzi futhi iqondise izinhlanzi kuyo.

(3) Umlomo wensimbi we-cone yangaphakathi ulungele ukwethulwa ngokuqondile kwezinhlanzi.

(4) I-cutout emise okume ukubamba Hlanganisa ukubamba ngokuvala okunefasitela ukuze ukhulise umphumela wokudoba.

2. Umgomo wokusebenza we-overshot yewindi

Lapho inhlanzi ingena kusilinda futhi iphushela olimini lwefasitela, ulimi lwefasitela lunwebeka lubheke ngaphandle, amandla alo abuyele emuva aluma umzimba wezinhlanzi ngokuqinile, nolimi lwefasitela nalo lubopha ngokuqinile izinyathelo, okungukuthi, inhlanzi iyabanjwa.

3. Indlela yokusebenza ye-overshot yewindi

(1) Hlola ukuthi imicu noma amashisela engxenye ngayinye aphelele futhi aqinile. Linganisa ukuthi usayizi wolimi lwefasitela kanye nobubanzi obuncane bangaphakathi besimo esivaliwe bungalingana nezinhlanzi, futhi ugcine isithombe ukuze uthole olunye uphenyo.

(2)Bamba phansi ufike ku-2~3m ngaphezulu kwenhlanzi, bese uqala iphampu ukugeza umthombo. Zungezisa kancane intambo yokubhoboza ukuze wehlise. Qaphela ukuguqulwa kwesikali sesisindo kanye nokungena kwesikwele, khumbula ukuthinta izinhlanzi ukuze ungene, futhi uqondise isilinda ukuze ungene ezinhlanzi.

(3)Qhubeka wehlisa intambo yokubhoboza ukuze wenze izinhlanzi zingene emgodini ongaphakathi wombhobho wamathuluzi. Uma ubude bezinto eziwayo bufushane, umthombo ujulile, futhi kunzima ukwahlulela ukungena kwesikwele kanye nokuguqulwa kwesisindo sokumiswa, intambo yokubhoboza ingaphakanyiswa ngo-1-2m ngemuva kokudoba okukodwa, bese ijikeleziswa futhi. wehlisiwe. Phinda izikhathi eziningana ukuze uphakamise i-drill.

(4) Lapho uphakamisa i-drill, kufanele isetshenziswe kahle. Ungathinti izinhlanzi bese ushaya intambo yokubhoboza ngokuzumayo, ukuze unganyakazi izinhlanzi phansi bese uwela emgodini futhi.
