Description

Technical Field

[0002] Rope ladders are ladders with ropes on both sides and steps made of rope, wood or metal. There are many types of rope ladders, and different types of rope ladders have different uses. A ship's rope ladder is a boarding tool specially designed for use on ships. It is mainly used for passengers and crew to board lifeboats or life rafts in emergencies, as well as to get on and off the cabin in daily use. This type of rope ladder is usually made of high-quality materials, such as sisal rope and eucalyptus treads, to ensure its durability and safety.

[0003] After searching, it is found that a typical rope ladder in the prior art is disclosed in CN213087898U, which is a marine rope ladder, including a composite rope, a plurality of stepping plates are arranged on the surface of the composite rope, both ends of the composite rope are fixedly connected with fixing rings, a non-slip cylinder located between two stepping plates is fixedly sleeved on the surface of the composite rope, the interior of the stepping plate is a hollow structure, and a grip groove is provided on one side of the stepping plate. The marine rope ladder, through the coordinated use of the grip groove, the non-slip cylinder and the contact rod, opens a grip groove on the front of the stepping plate, and the non-slip cylinder is fixedly sleeved on the surface of the composite rope. When climbing, the climber can hold the stepping plate or the non-slip cylinder through the grip groove, which is convenient for the climber to climb, and avoids the inconvenience of the climber's operation due to the lack of a designated hand fixing mechanism when using the traditional marine rope ladder.

[0004] To sum up, when the existing rope ladder is in use, the entire rope ladder shakes violently as the climbers move, thereby interfering with the climbers and hindering their smooth climbing. Secondly, when the rope ladder is not in use, it is directly placed on the shipboard, which can easily affect the service life of the rope ladder.
