Scientific investigation ship with full-automatic folding rotary gangway ladder

Abstract

The invention discloses a scientific investigation ship with a full-automatic folding rotary gangway ladder. The scientific investigation ship comprises a ship body, a containing cavity, an upper platform frame arranged in the containing cavity and a gangway ladder body connected with the upper platform frame in a rotating and folding mode, and a boarding platform is arranged at the end of the gangway ladder body. The gangway ladder body comprises two rod bodies extending in the length direction of the upper platform frame, a plurality of supporting rods used for walking and treading are evenly arranged between the two rod bodies in the length direction of the rod bodies, a rotating mechanism used for driving the upper platform frame and the gangway ladder body to rotate in the horizontaldirection to be away from the ship body or reset is arranged on the ship body, the upper platform frame and the gangway ladder body are provided with an automatic chain plate folding and unfolding system which is used for uniformly paving flexible chain plates on the supporting rods and forming a walking platform when the upper platform frame and the gangway ladder body rotate to be far away fromthe ship body. The gangway ladder is more convenient to overturn, fold and rotate, automatic folding and overturning folding and unfolding of the gangway ladder are achieved, the influence of resistance can be effectively avoided, the efficiency is high, and work is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a scientific research ship with a fully automatic folding rotary gangway. 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...

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
