Kodi anthu akumafakitale ayenera kusankha bwanji zida zoboola miyala?
Ndi chitukuko chofulumira cha zomangamanga zapadziko lonse lapansi, kufunikira kwa zida zobowola miyala m'magawo a uinjiniya monga migodi, zomangamanga, zomangamanga, zomangamanga ndi chitukuko cha misewu kwawonetsa kukwera, ndipo zofunika zapamwamba zakhazikitsidwa pazabwino, zosiyanasiyana. ndi magwiridwe antchito a zida za brazing.
Malinga ndi mitundu yamakina obowola miyala omwe amagwiritsidwa ntchito pobowola geotechnical, zida zothandizira pobowola miyala zimatha kugawidwa m'mitundu isanu ndi umodzi: Zida zoboola nyundo zapamwamba, Down the Hole Hammer Bits, zida zobowola migodi, zida zobowola pabwalo ndi kumbuyo. zida pobowola geological kufufuza.
Zida zapamwamba zobowola nyundo
Zida zobowola nyundo zapamwamba zili pamwamba pa makina obowola miyala. Imadalira pisitoni ya kubowola mwala kuti ikhudze mwachindunji mchira wa chida chowombera. Mphamvu yamphamvu yomwe imapangidwa imafika pamutu wa brazing kudzera mu thupi la brazing mu mawonekedwe a mafunde opanikizika kuti amalize kusweka kwa thanthwe. Njira yobowola mwala iyi imagwiritsa ntchito gasi wothinikizidwa kapena mafuta a hydraulic ngati gwero lamagetsi, ndipo mphamvu yamphamvu imatha kupangidwa molingana ndi zofunikira za zida, motero imakhala ndi mphamvu yayikulu.kubowola miyalamlingo. Kuzama kwa dzenje la mtundu uwu wa pobowola chida nthawi zambiri si upambana 35M, ndi pobowola awiri si upambana 152M. Chida chobowola mwala chapamwamba kwambiri chikhoza kugawidwa m'magulu awa:
(1) Zida zopangira ng'anjo zamakina opepuka amiyala. Kulemera kwa makina obowola miyala amtunduwu ndi ochepera 35KG. Amagwiritsa ntchito manja amanja kapena kuthandizira miyendo ya mpweya ngati nsanja yogwirira ntchito. Mphamvu ndi kuthamangitsidwa kwa kukumba miyala ndizochepa. Nthawi zambiri, zida zopangira zida ndi H19mm ndi H22mm hexagonal integral brazing rods, komanso 38-42mm mitu yoboola yoboola pakati, mitu yowotcha yopingasa ndi mano anayi ndi mano asanu Tapered button bit Rock Drill.
Zida zazikulu kwambiri zobowola miyala zopepuka zomwe zimagwiritsidwa ntchito pamsika waumisiri wobowola miyala wapanyumba ndi ndodo za H22mm zolumikizidwa ndi cone ndi mitu ya solder yooneka ngati flake. Zina mwa izo, Φ38-Φ43mm ozungulira mano anayi ndi mano asanu cone cholumikizira brazing mutu ndi kuwala kobowola chida chida chopangidwa m'zaka zaposachedwa ndi chitoliro cha H22mm. Chifukwa cha moyo wake wokhazikika wautumiki komanso liwiro la kubowola mwachangu mumitundu yolimba ya rock, yadziwika ndi gulu lomanga.
(2) Zida zopangira migodi yopangira migodi mobisa. Zopangira migodi pansi pa nthaka zimapanga gawo lalikulu lazinthu zamigodi. Nthawi zambiri, migodi yapansi panthaka imatha kugawidwa m'mitundu itatu: kubowola mwala wosaya (6m), kubowola miyala yapakatikati (kuzama kwa pore 10-30m) ndi kubowola thanthwe lakuya (dzenje lakuya 50-60m). Pamabowo okhala ndi pansi pa 43mm, ndodo zomangira zomangira za H22mm ndi zobowola, zopingasa, kapena zozungulira-mano nthawi zambiri zimagwiritsidwa ntchito. Pamabowo okhala ndi kabowo kakang'ono kuposa 43mm, R32-H25-R32 * 1000m dirll pipe imagwiritsidwa ntchito, limodzi ndi mitu yoboola miyala yozungulira yozungulira kapena yozungulira.
