| description | An injection head shifting system for underwater operation relates to the technical field of coiled tubing drills and comprises a control system, a derrick, a roller, a power mechanism and an injection head, a shifting mechanism is connected between the injection head and the derrick and comprises a pulley block and a steel wire rope, and the pulley block is connected with the injection head and used for controlling the injection head to shift in the vertical direction. The driving mechanism is used for winding and unwinding the steel wire rope and is electrically connected with the control system through a cable. The integral displacement control of the injection head of the continuous pipe drilling machine can be realized by only using a set of combination of the pulley block and the hydraulic winch, the continuous pipe is always centered with a wellhead, the high efficiency of operation can be ensured, and the complete underwater operation process can be further realized.
