Development and Performance Analysis on Multi-purpose Mechanically-driven Underground Drill

Abstract:

The paper describes a new type of multi-purpose underground drill. It combines rotator of spindle rig with 360 turning, and for the advantages of lower energy-consuming mechanical driving and convenient maintenance, the main parts of current GXY-2 series rigs are adopted with lower and upper hydraulic chucks and positioning outfit adding to realize all-direction holes construction, the cost of manufacture, application and maintenance are greatly reduced. It is proved by in-plant debugging and preliminary production test that the performance of the drill is fully realized.

Key words:underground drill; three-chuck holding system; automatic break-out drilling rod; all-direction hole
