Adjustable boarding ladder device

Abstract

The invention provides an adjustable boarding ladder device, and belongs to the technical field of ships. The adjustable boarding ladder device solves the technical problems that a boarding ladder is large in size, poor in flexibility and narrow in application range. The adjustable boarding ladder device comprises a sliding table, a sliding seat, at least one boarding ladder main body and an accommodation ladder. The sliding table extends in the axial direction and is placed on a dock platform. The sliding seat is movably arranged on the sliding table. The at least one boarding ladder main body is arranged on one side of a ship body in a suspension mode, and fixedly connected with the ship body. The accommodation ladder is located between the sliding seat and the boarding ladder main body, and movably connected with the sliding seat and the boarding ladder main body. The sliding seat can move in the axial direction on the sliding table, and the accommodation ladder can rotate in the horizontal direction and the vertical direction relative to the sliding seat and the boarding ladder main body correspondingly. When the height of the boarding ladder main body is changed, the change of the height of the boarding ladder main body can be matched through movement of the sliding seat on the sliding table and rotation of the accommodation ladder relative to the sliding seat and the boarding ladder main body, and the adjustable boarding ladder device is flexible to use, relatively high in safety and relatively low in cost.

Description

technical field [0001] The invention belongs to the technical field of ships, and relates to a boarding ladder device, in particular to an adjustable boarding ladder device. Background technique [0002] The boarding ladder is a device for loading and unloading operators and crew members to safely and smoothly get on and off the ship when the modern large-scale dock ship is docking at the dock. [0003] Currently there are the following technical problems in the dock boarding ladders used in the field of shipbuilding and repair. 1. In order to increase its stability, the boarding ladders are usually large in size, heavy in weight and inconvenient for transportation; 2. Due to the size of each ship type And the depth of the ship is different, the main deck of the ship may be higher or lower than the height of the boarding ladder, so that the traditional boarding ladder cannot be applied to different types of ships, and it must be equipped with multiple corresponding types of ...

Problems solved by technology

[0003] Currently there are the following technical problems in the dock boarding ladders used in the field of shipbuilding and repair. 1. In order to increase its stability, the boarding ladders are usually large in size, heavy in weight and inconvenient for transportation; 2. Due to the size of each ship type And the depth of the ship is different, the main deck of the ship may be higher or lower than the height of the boarding ladder, so that the traditional boarding ladder cannot be applied to different types of ships, and it must be equipped with multiple corresponding types of boarding ladders to be applicable to different types of boarding ladders. The type of ship increases unnecessary cost loss; 3. With the rising and falling tides at the seaside and the influence of the wind direction when the ship docks at the pier, the height between the ship and the pier will change, while the traditional boarding ladder adopts a fixed form and cannot be flexible It moves with the ship, which is more restrictive and has potential safety hazards
