Txiav txiav yog cov cuab yeej siv hauv cov tshuab mining los txiav cov thee thiab pob zeb. Lawv suav nrog lub shank, lub taub hau carbide, qhov ntev ntev, thiab qhov ntev ntawm cov hniav, feem ntau ruaj ua ke los ntawm cov txheej txheem vuam lossis inlay. Txiav txiav tuaj ntau hom thiab qauv, ua rau lawv yooj yim tsis meej pem. Kev hais lus dav dav, txiav txiav tuaj yeem muab faib ua ob pawg raws li lawv daim ntawv thov: mining txiav picks thiab engineering txiav picks. Niaj hnub no, peb yuav qhia txog mining txiav picks.
Mining txiav picks feem ntau yog siv nyob rau hauv thee mining. Lawv txiav cov cuab yeej siv rau hauv cov tshuab mining thiab cov tshuab tunneling los khawb thiab tawg cov thee lossis pob zeb.
Mining txiav picks tuaj yeem muab faib raws li lawv cov duab ua ob pawg loj: "pick-zoo li tus txiav" thiab "riam-zoo li tus txiav." Raws li hom tshuab siv, lawv tuaj yeem muab faib ua "thee mining machine cutting picks, tunneling machine cutting picks, together mining machine cutting picks, and roadheader cutting picks." Tam sim no, thee mining tshuab txiav picks thiab tunneling tshuab txiav picks yog feem ntau siv.
Txiav hniav vs. Xaiv-Cov hniav txiav zoo li
Txiav cov hniav tuaj yeem paub qhov txawv ntawm lawv cov tsos. Cov uas muaj cov lus qhia conical yog tapered txiav cov hniav, thaum cov uas muaj cov lus qhia tiaj tus yog cov hniav txiav.
Coal mining tshuab txiav hniav
Coal mining tshuab txiav cov hniav yog cov cuab yeej txiav tseem ceeb ntawm lub nruas ntawm lub tshuab hluav taws xob hauv av. Lawv tau nruab rau ntawm lub nruas ua ke nrog cov tes tsho hniav thiab cov hniav, thiab yog cov khoom siv coj los siv rau kev txiav. Lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev tsim khoom, kev siv hluav taws xob, kev ua haujlwm ruaj khov, thiab kev pabcuam lub neej ntawm lwm yam khoom siv ntawm cov thee mining machinery.
Cov qauv tseem ceeb ntawm thee mining tshuab txiav cov hniav suav nrog U47, U82, U80 series (U82, U84, U85), U90 series (U92, U94, U95), thiab U170, thiab lwm yam.
Lub caij no, tunneling tshuab txiav cov hniav yog lub ntsiab txiav cov cuab yeej ntawm lub taub hau txiav (bombhead) ntawm lub tshuab tunneling. Lawv tau nruab rau ntawm lub taub hau txiav ua ke nrog cov rooj zaum hniav thiab yog ib qho ntawm cov khoom siv hauv kev khawb av. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau lub tshuab tunneling lub peev xwm ntau lawm, kev siv hluav taws xob, kev ua haujlwm ruaj khov, thiab kev pabcuam lub neej ntawm lwm yam khoom siv.
Cov qauv tseem ceeb ntawm tunneling tshuab txiav xaiv suav nrog: U47, U135, S100, S120, S150, S110, S200, S260, thiab S160.
Daim ntawv thov ib puag ncig ntawm engineering txiav xaiv txawv ntawm cov mining txiav picks; ib tug yog nyob rau ntawm txoj kev nto, thiab lwm yam yog underground. Ib qho yog ib qho khoom siv rau kev tsim kho tshuab, thiab lwm qhov yog cov khoom siv rau mining lossis tunneling machinery. Raws li hom tshuab, engineering txiav picks tuaj yeem muab faib ua dav dav rau hauv: rotary drilling rig txiav picks, milling tshuab txiav picks, thiab lwm yam. Cov kev siv tshwj xeeb zoo ib yam li cov mining txiav picks; ob qho tib si yog ntsia rau ntawm cov tshuab mining.
