Abstract

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.
