包钢白云鄂博铁矿自1987年引进 KY-310型牙轮钻机,现已成为主体穿孔设备。KY-310型牙轮钻机的回转机构采用顶部回转机构,其回转小车在提升封闭链条、加压齿轮的共同作用下,可沿钻架齿条上下移动,其导向方式采用滑板导向,作用是使加压齿轮沿钻架齿条上下滚动时保持齿面接触紧密,同时使 Baotou Bayanobo Iron Ore since the introduction of KY-310-type cone drill, has now become the main piercing equipment. KY-310 type rotary drilling rig rotary mechanism using the top of the rotary mechanism, the rotary car in the lifting of the closed chain, under the joint action of the pressure gear can move up and down along the rack rack, the guide way using the slider-oriented role is to make Pressurized gear along the rack racks up and down to keep the tooth surface contact closely while making
