    潜孔钻机是利用潜入孔底的冲击器与钻头对岩石进行冲击破碎,因此,称为潜孔钻机。广泛用于金属矿山、水电、交通、建材、港湾和国防工程中。潜孔钻机可以在中硬以上(f≥8)的岩石中钻孔。钻机价格比较便宜,特别适用于中小型露天矿。

    潜孔钻机产品分类

    1、根据使用地点不同,分为井下潜孔钻机和露天潜孔钻机两大类。如:井下潜孔钻机有K7—80、KQJ—100型,露天潜孔钻机有KQ—100、KQ—150、KQ—200、KQ—250型。

    2、根据孔径不同,分为轻型潜孔钻机(孔径为80~100mm,机重为数百公斤到2~3吨)、中型潜孔钻机(孔径为150mm,机重为10~15吨)、重型潜孔钻机(孔径为200mm,机重为25~35吨),特重型潜孔钻机(孔径为250mm,机重为40~45吨)。

    潜孔钻机工作原理

    潜孔钻机的工作原理与其它凿岩机一样,都有冲击、转动、排碴和推进等凿岩成孔过程,同属于冲击转动式钻孔。不同之处在于:潜孔钻机的冲击器装在钻杆的前端,潜入孔底,随钻孔的延伸而不断推进。

    潜孔钻机特点

    ① 冲击能量损失不随钎杆的加长而增加,可凿钻大孔直径的深孔;

    ② 工作面噪音大大降低;

    ③ 钻进速度快,机械化程度高,辅助作业时间少,提高了钻机的作业率;

    ④ 机动灵活;

    ⑤ 钻孔质量高;

    ⑥ 能钻凿中硬或中硬以上(f≥8)的岩石。
