A fully automatic folding rotary gangway for ships

Abstract

The invention discloses a marine fully automatic folding rotary gangway, which comprises an upper platform frame connected with the hull, and a gangway body connected to the upper platform frame by rotating and folding. Rod body, along the length direction of the rod body, a number of support rods for walking and stepping are evenly arranged between the two rod bodies. The frame and the gangway body are equipped with an automatic chain plate retractable system that evenly lays flexible chain plates on the support rods to form a walking platform when the upper platform frame and the gangway body rotate away from the hull. When the gangway is in use, the flexible chain plate is started for laying, and the flexible chain plate can be rolled up when not in use, which not only reduces the weight of the entire gangway, but also reduces the demand for power when retracting and unwinding, saving energy.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a fully automatic folding rotary gangway for ships. Background technique [0002] The gangway is an important tool used by offshore platforms or ships. It is usually stored inboard of the ship, and when it is used, it is released outboard and arranged along the side of the ship. The ladder used for people to get on and off the ship can be used for the transportation and transfer of people or goods between offshore platforms. For example, when offshore wind turbine maintenance personnel land from the operation and maintenance ship to the basic platform of the wind turbine, they need to use a gangway to land. Therefore, the gangway has become an essential device for large and medium-sized ships. It is an important passage for the pilot to board the ship when the supporting ship enters the port. When the ship sets sail, the gangway must be stored on the side deck of the ship. In orde...

AI Technical Summary

Problems solved by technology

[0008] To sum up, the current development of gangway technology has greatly improved the problems of difficult installation, inconvenient use, and poor safety guarantees of traditional bulk carriers, container ships, and large cruise ships. Some pitfalls of the application process

For example, although the current retractable or adjustable gangway has many functions, is easy to operate, and saves space, its structure is relatively complicated. Since it is installed on the side of the ship or on the deck, it still needs to occupy some space in the deck or cabin.

And although it is convenient to expand and contract, the process of retracting and deploying requires the assistance of hoisting equipment. For ships, these auxiliary operating equipment still need to be installed, which is troublesome in operation, and although the telescopic gangway structure solves the problem of convenient expansion and contraction, in fact The space occupied by this telescopic structure is still relatively large

The gangway installed on the port does not occupy the space of the ship's side deck, and has relatively complete functions and a high degree of automation, but it is necessary to consider the position of the gangway when the ship calls at the port. Correspondence is also a relatively difficult problem to control
