The invention relates to the technical field of rotary drilling rigs, in particular to a rotary hole alignment method and a rotary hole alignment mechanism. The rotary hole alignment method comprisesthe following steps of judging the rotation angle of a rotary drilling rig, and when the rotation angle is smaller than a first angle and greater than a second angle, controlling the rotary hole alignment mechanism to drive the rotary drilling rig to rotate, wherein the rotation angle of the rotary drilling rig is a preset angle; judging the rotation angle of the rotary drilling rig after rotation, when the rotation angle of the rotary drilling rig after rotation is greater than the second angle, controlling the rotary hole alignment mechanism to drive the rotary drilling rig to rotate, and controlling the rotation angle of the rotary drilling rig to be smaller than the angle of the last rotation; and continuing the operation until the rotation angle of the rotary drilling rig is less thanor equal to the second angle. The method can improve the stability of the rotation and shorten the time of rotating to the zero position.
Description
technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to a rotary hole alignment method and a rotary hole alignment mechanism. Background technique [0002] At present, because the mass of the rotary drilling rig itself is large and the rotary inertia is large, there is a problem that the time required for the rotary drilling rig to return to the zero position is too long during the rotary process. Contents of the invention [0003] The purpose of the present invention includes, for example, to provide a rotary hole alignment method and a rotary hole alignment mechanism, which can improve the stability of the rotation and shorten the time for the rotation to the zero position. [0004] Embodiments of the present invention can be realized like this: [0005] In the first aspect, the embodiment provides a rotary hole alignment method, the rotary hole alignment method includes the following steps: [0006] Judging the rot...
