Development and Application of Portable Dual-use Drilling Tower for Medium-deep Vertical and Inclined Holes

Abstract:

Based on the investigation on homemade spindle core drilling machine, designing plan was put forward to dual-use drilling tower for vertical and inclined holes, which changed the history that homemade spindle core drilling machine could not be used in inclined hole construction, further developed application range of homemade spindle core drilling machine. The paper introduced the drilling machine about design principle, structure design and effect of production test.
