改装G-2型钻机用于藏北砂钻施工

Use of Refitted G-2 Type Drilling Machine for Drilling Sands in North Tibet

目前国内不生产专用砂钻机,通过对G-2型工程钻机进行适当改造,加大柴油机的功率,加装副卷扬,去掉动力头,设计加工专用的套管夹持器和组合吊锤,实现了机械拧卸套管,大大减轻了劳动强度,提高了该型设备对藏北高原恶劣自然条件的适应能力。

Drilling machine for special use for drilling sands has not been made for the present at home. Refitted G - 2 type drilling machine is equipped with diesel engine with larger power, hoister equipment, special casing clamper and composite hammer and is characterized by reducing labor intensity and enhancing adaptability to adverse natural conditions in north Tibet.
