一、钢球定向器的用途和特点这种定向器用于斜孔或直斜孔,或打分支定向孔需人工弯曲,按预定方向下入偏心楔子时;以及绕过孔内事故钻具补采岩矿心而需下偏斜楔子时,确定下楔子的方向.这种定向器结构比较简单,定向比较可靠,而且可以利用废、旧料加工,成本也低.能适用于下开口楔和闭口楔两类楔子,克服了ZDC-1钻孔定向仪只适用于下开口楔子的局限性.
First, the use and characteristics of the steel ball director This directional device for oblique hole or straight oblique hole, or hit the branch directional hole to be artificial bending, according to a predetermined direction into the eccentric wedge; and bypass the accident recovery drill hole mining Rock cores and the need to lower the wedge, determine the direction of the next wedge. This directional structure is relatively simple, more reliable orientation, and can use waste, old materials processing, low cost. Can be applied to the next open wedge and closed mouth Wedge two types of wedges to overcome the limitations of the ZDC-1 drilling direction finder only applies to the next opening wedge.
