Introduction
The lifting ring of the core drilling rig is connected with the ring seat with a pin shaft, the ring seat and the hook rod are welded into one body, the cylinder body and the hook body are connected with the left thread, and a stop block is used to prevent the thread from loosening. The hook body and cylinder can move up and down along the hook rod. The function of the inner and outer load springs is to make the vertical root loosen and spring up when the drill is pulled out.

How does a core drilling rig work?
The lifting ring of the core drilling rig is connected with the ring seat with a pin shaft, the ring seat and the hook rod are welded into one body, the cylinder body and the hook body are connected with the left thread, and a stop block is used to prevent the thread from loosening. The hook body and cylinder can move up and down along the hook rod. The function of the inner and outer load springs is to make the vertical root loosen and spring up when the drill is pulled out.
The barrel of the core drilling rig is equipped with oil. The seat ring of the thrust bearing divides the oil chamber into two parts, and there are oil holes on the seat ring. Due to the damping effect of the oil flow, it absorbs the shock and vibration of the hook body during its tripping operation, which can prevent the thread damage of the drill pipe joint.
The upper end of the cylinder of the core drilling rig is composed of 6 small springs and a positioning plate to form a positioning device. With the help of the friction between the positioning and the annular contact surface of the ring seat, it can prevent the rotation of the ring when the empty elevator is lifted.、
