Description

Marine rope ladder winding and unwinding devices Technical Field The utility model relates to the technical field of marine equipment, in particular to a marine rope ladder retraction device. Background For the safety of the airlines, pilot needs to guide the ships to enter and leave the port when entering and leaving the port, and the two sides of the ship need to be provided with rope ladders so that the pilot can safely boarding and disembark. When the ship runs normally, the rope ladder is normally stacked on the main deck close to the ship side, and is wound and fixed on the main deck by using ropes, and when the ship enters and exits, the shipmen put down the rope ladder close to the ship side outer plate, so that the shipmen climb on the ship. However, when the rope ladder is stored, the space on the main deck can be correspondingly occupied, the width of an escape passage of a ship is affected, if the stacking width of the rope ladder is reduced, the stacking height of the rope ladder is too high, the fixing effect of the rope ladder is poor, the rope ladder is easy to incline and damage, and meanwhile, the conventional manual lifting mode is laborious, and the recycling difficulty is high.
