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.

Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] See figure 1 , figure 2 , the present invention includes a ladder frame 1 and an inclined ladder 2, the top of the ladder frame 1 is connected to a telescopic frame 4, and the top of the telescopic frame 4 is fixedly connected to a hook 5. The telescopic frame 4 includes vertical rods 40 and beams 41 connected between the vertical rods 40 . The vertical rods 40 on both sides are sleeved in the rods 10 on both sides of the ladder frame 1 and fastened by means of the toggle 3 .

[0014] When the present invention is not in use, the telescopic frame 4 is stored in the ladder frame, and when it needs to be fixed by a hook, it is only necessary to extend the telescopic frame 4 to a suitable position, and use the pull button 3 to fix the telescopic frame on the ladder frame. Ladder utilizes hook 5 to hang on the rod on the hull. The inv...

Abstract

The invention relates to a safety boarding ladder for a ship, the safety boarding ladder comprises a ladder frame and an inclined ladder. The marine safety boarding ladder is characterized in that the top part of the ladder frame is connected with a telescopic frame, and the top end of the telescoping frame is fixedly connected with hooks. The defect of inflexible use of traditional fixed type marine boarding ladders can be overcome. Compared with existing movable type boarding ladders for the ship, the safety of use can be improved, and the occupied space can be reduced. The safety boarding ladder for the ship has the advantages of simple structure and easiness in operation, and a good basic appliance can be provided for the ship.

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...
