ROV umbilical cable winch and management system, including: frame, gantry swing arm, winch device, winch, pulley device; The frame is set on the side of the mother ship's hull, and is made of rectangular pipes welded together. The front end of the frame is equipped with an i-type swing arm, and the rear end of the frame is equipped with a winch device. A winch is installed above the winch device, and the pulley device is connected to the door type swing arm; The steel cable and umbilical cable are connected to the ROV through a pulley device. The winch controls the retraction of the steel cable, and the winch device controls the retraction of the umbilical cable. The ROV is driven up and down through the rotation of the swing arm.
The door type swing arm is welded from a rectangular tube and a circular tube. The door type swing arm includes a swing arm, a fixed arm, a connecting rod, a connecting plate, a sliding groove, and a hydraulic device. The swing arm is connected to the fixed arm through a connecting rod, and a connecting plate is provided between the swing arm and the fixed arm. The connecting plate is provided with a sliding groove, and hydraulic devices are respectively provided on both sides of the I] - type swing arm. The hydraulic device includes an upper hydraulic cylinder, a lower hydraulic cylinder, and a middle pin. The middle pin is fixed on the connecting rod, and the middle pin slides in the sliding groove. The upper hydraulic cylinder is connected to the swing arm, and the lower hydraulic cylinder is set on the frame. The cylinders are connected by an intermediate pin, and the upper and lower hydraulic cylinders drive the connecting rod to rotate through the intermediate pin, which in turn drives the swing arm to rotate.
The winch device includes a winch, a main shaft, a conductive slip ring, a servo motor, a synchronous pulley, a gearbox, gears, and a ring gear; The winch is equipped with two main shafts on each side, which are connected to the frame by bearing seats. One of the main shafts is equipped with a conductive slip ring, and an umbilical cable is wound on the winch. One end of the umbilical cable is inserted into the main shaft through a hole on the winch and connected to the conductive slip ring; The servo motor is connected to the second speed gearbox through a synchronous belt pulley, and drives the second speed gearbox to rotate. The output shaft of the second speed gearbox is equipped with gears, and the winch is equipped with a ring gear. The gears are connected to the ring gear through a synchronous pulley; The servo motor transmits power to the winch, driving it to rotate and achieve the winding and unwinding of the umbilical cable.
The ROV umbilical cable winch and management system also includes a manual umbilical cable retraction device, which is set on one side of the winch device; The manual umbilical cable device comprises a handwheel, a manual worm gear box, and a sprocket. The handwheel is connected to the manual worm gear box, and the manual worm gear box is connected to the output shaft of the second speed gearbox through the sprocket. The handwheel drives the manual worm gear box to rotate, and the manual worm gear box drives the output shaft of the second speed gearbox to rotate through the sprocket. The gear on the output shaft drives the ring gear to rotate the winch, playing a role in winding and releasing the umbilical cable.
