一种在在线使用的管线的管壁上钻孔的设备
摘要：
一种在在线使用的管线的管壁上钻孔的设备，包括一支承机构、一钻具转动机构、一钻具移动机构和一动力‑减速机构；该支承机构将该钻具转动机构和该钻具移动机构支承在该管线内；该动力‑减速机构与该钻具转动机构传动相连，驱动该钻具转动机构的第一轴转动，该钻具移动机构驱动该钻具转动机构的该第一轴移动；该动力‑减速机构位于该管线外部。这种在在线使用的管线的管壁上钻孔的设备操作方便。
摘要（英）：

The invention provides a drilling device for the pipe wall of a pipe in use. The drilling device comprises a bearing mechanism, a drilling tool rotating mechanism, a drilling tool movement mechanism and a power-reducing mechanism. The drilling tool rotating mechanism and the drilling tool movement mechanism are supported in the pipe through the bearing mechanism. The power-reducing mechanism is connected with the drilling tool rotating mechanism in a transmission mode to drive a first shaft of the drilling tool rotating mechanism to rotate. The drilling tool rotating mechanism drives the first shaft of the drilling tool rotating mechanism to move.
