Safety ladder assembly on ship

Abstract

The invention relates to a safety ladder assembly on a ship. The safety ladder assembly comprises a ladder assembly body and an inclined ladder, wherein the top of the ladder assembly body is connected with a retractable frame; the top of the retractable frame is fixedly connected with a hook; the retractable frame comprises vertical rods on the two sides and a transverse beam which is fixedly connected between the vertical rods on the two sides; the vertical rods of the retractable frame are sleeved with two side rods of the ladder assembly body and are fixedly connected with the ladder assembly body by plate buckles; and the side rods of the ladder assembly body are fixedly connected with a plurality of rubber sleeves. By virtue of the safety ladder assembly, the defect that a traditional fixed ship climbing ladder is inflexible to use is overcome; and compared with an existing movable ship climbing ladder, the safety ladder assembly has the advantages that the use safety is improved and the occupying space is reduced.

Description

technical field [0001] The invention relates to the field of marine appliances, in particular to a marine boarding ladder. technical background [0002] The climbing tool commonly used on ships is a climbing ladder, and existing climbing ladders include two kinds of fixed climbing ladders and movable climbing ladders. The fixed climbing ladder includes a ladder frame. The top of the ladder frame includes lifting lugs. The bottom of the ladder frame is fixedly connected to the berth by means of bolts or steel nails. The disadvantage of the fixed climbing ladder is that the center of the climbing ladder and the berth are relatively fixed. The ships need to be equipped with boarding ladders of various specifications. The movable climbing ladder is a moving climbing ladder. In use of the existing climbing ladder, since the top of the climbing ladder leans against the ship wall, the top and the ship wall are not fixed, so the bottom of the climbing ladder must be in contact with...

Problems solved by technology

The fixed climbing ladder includes a ladder frame. The top of the ladder frame includes lifting lugs. The bottom of the ladder frame is fixedly connected with the berth by means of bolts or steel nails. The disadvantage of the fixed climbing ladder is that the center of the climbing ladder and the berth are relatively fixed. The ship needs to be equipped with various specifications of boarding ladders

The movable climbing ladder is a moving climbing ladder. In use of the existing climbing ladder, since the top of the climbing ladder leans against the ship wall, the top and the ship wall are not fixed, so the bottom of the climbing ladder must be in contact with the ship wall when in use. Only by keeping a large distance between them can the slide phenomenon be avoided. Therefore, this kind of slide takes up a lot of space when used, and it cannot completely ensure the vibration slide phenomenon that occurs when the ship is sailing, resulting in low safety performance.
