Drill rod grabbing manipulator for drilling machine and grabbing method

The invention relates to the technical field of geological drilling, in particular to a drilling rod grabbing manipulator for a drilling machine and a grabbing method. The drilling rod grabbing manipulator for the drilling machine comprises a mounting frame, a horizontal moving device, a turnover device and a manipulator body. The turnover device pushes the first connecting point of the manipulator to rotate around the second connecting point so that the clamping axis of the manipulator can be parallel to the axis of the drill rod, the manipulator clamps and drives the drill rod to move in the axis direction so that the drill rod can be away from or close to the ground, and the horizontal moving device drives the drill rod to move to the placing area of the drill rod placing frame through the manipulator. The drilling rod grabbing manipulator for the drilling machine can be separated from the drilling machine, can adapt to drilling machines in various forms, and is wider in adaptability. By means of the horiz
