The invention relates to the technical field of a rotary drilling rig, in particular to an adjusting device for a rotary drilling rig and a rotary drilling rig. The adjusting device comprises a door frame, a chassis platform, a mast oil cylinder and a mast. The door frame is connected with the chassis platform through a first hinged joint and a second hinged joint in a hinged mode; one end of themast oil cylinder is connected with the door frame through a third hinged joint in a hinged mode, and the other end of the mast oil cylinder is connected with the mast in a hinged mode; and the thirdhinged joint, the first hinged joint and the second hinged joint are sequentially arranged from top to bottom, the first hinged joint is located between the second hinged joint and the mast, and the first hinged joint is located between the third hinged joint and the mast. The door frame and the chassis platform are connected in a hinged mode through the first hinged joint and the second hinged joint to enable the door frame to move to the left, a support angle [theta] of the mast oil cylinder is enlarged, and the mast can be more steadily supported by the mast oil cylinder. At the same time,the size and weight of the door frame are reduced to reduce cost, and the machining technology is improved.
