Description
Technical Field
The invention relates to the technical field of ships, in particular to a scientific investigation ship with a full-automatic folding rotary gangway ladder.
Background
The gangway ladder is an important tool used by offshore platforms or ships, is stored in a ship board at ordinary times, is obliquely arranged along a gangway edge after being released outside the ship board when in use, is used for personnel to get on or off the ship, and can be used for transporting and transferring personnel or goods between the offshore platforms. For example, when an offshore wind turbine maintenance worker logs in to a wind turbine foundation platform from an operation maintenance ship, the offshore wind turbine maintenance worker needs to log in by means of a gangway. Therefore, the gangway ladder becomes a necessary device of large and medium-sized ships, is an important channel for pilot to board when the ships enter a port, and needs to be stored on a ship board deck when the ships start. In order to reduce the storage space of the gangway ladder, manufacturers design the gangway ladder into a two-section telescopic structure, namely a lower ladder and an upper ladder are coaxially sleeved, and the lower ladder is extended out of the upper ladder by gravity or in a steel cable traction mode when the gangway ladder is released. The axial nesting structure is simple and compact, can be extended and contracted, can obviously reduce the length size of the accommodation ladder in a storage state, and can meet the matching requirements of ships such as oil tankers, bulk cargo ships and the like. However, since a large number of container ships and large cruise ships are arranged on the deck, the space of the ship board deck is not wide, the storage position of the gangway ladder is limited, and if two sections of telescopic gangways ladders in the prior art are still selected, on one hand, the installation difficulty of manufacturers is high, and on the other hand, the ship side is inconvenient to use in the future.
With the development of shipbuilding industry, the single-section gangway ladder used on the current ships is far from meeting the requirement. Therefore, the shipbuilding industry of various countries in the world carries out a great deal of research and improvement on the gangway ladder type and structure, and originally creates a plurality of gangway ladder devices which are convenient to use, flexible to operate, economical, durable, safe and reliable. The double-section telescopic gangway ladder correspondingly replaces the turnover type and single-section type gangway ladder devices in the past.

CN 104417718A discloses an automatic flexible upset gangway ladder, installs on the hull, includes: the telescopic gangway ladder comprises an upper platform frame hinged on a gunwale deck, an upper platform turntable is rotatably arranged on the upper platform frame, an upper gangway ladder is hinged on the upper platform turntable, and a lower gangway ladder is slidably arranged on the upper gangway ladder; the telescopic driving device is arranged between the ship body and the telescopic gangway ladder; the turnover device comprises an upright post, a turnover arm is hinged to the ship body, and a rotation locking device is arranged between the turnover arm and the upright post; the overturning driving device is arranged between the overturning device and the telescopic gangway ladder;
CN 102548838A relates to a device (1) for a length-variable ship gangway (2). According to the invention, the part (3) of the telescopic structure (4) forms a roadway surface on the gangway. Further, the device (50) for the ship ramp (2) has a device for locking the turntables of the telescopic ramp sections in priority order, and the ship ramp device (50) has turntables (51, 51A, 51B) between the ramp sections (10, 11, 12).
CN 106043606a discloses an adjustable gangway ladder, which includes a control tower, a fixed channel, a telescopic gangway ladder and a landing device, wherein the control tower is connected with one end of the fixed channel, the other end of the fixed channel is connected with one end of the telescopic gangway ladder, and the other end of the telescopic gangway ladder is connected with the landing device; the control tower is used for controlling the fixed channel and the telescopic gangway ladder to perform pitching motion and controlling the telescopic gangway ladder to stretch; the landing device is used for erecting the gangway ladder on the landing platform.
To sum up, the development of the prior gangway ladder technology has greatly improved the problems of large installation difficulty, inconvenient use and poor safety guarantee of various ships such as the traditional bulk cargo ship, the container ship, the large-scale cruise ship and the like, but the gangway ladder patent still has some defects in the prior gangway ladder application process. For example, although the telescopic or adjustable gangway ladder has multiple functions, is convenient to operate and saves space, the structure is relatively complex, and the space in the deck or the cabin still needs to occupy some positions due to the installation on the board or on the deck. And although flexible convenient, receive and release the process and need hoisting equipment to assist, this still needs to install these auxiliary operation equipment to boats and ships, and is more troublesome when the operation to telescopic accommodation ladder structure has solved flexible convenient problem, and the space that this kind of telescopic structure occupied is still bigger in reality. The gangway ladder installed on the port does not occupy the space of the ship board deck of the ship, has complete functions and high automation degree, but needs to consider the position of the gangway ladder when the ship stops at the port, and is relatively difficult to control considering that the ship stops and corresponds to the position of the gangway ladder on the port. Therefore, how to reduce the occupation of deck space to the maximum extent, installing the accommodation ladder at the ship board position of the ship and realizing the functions of fully automatic folding, unfolding, stretching and the like becomes a technical problem which is urgently needed to be solved in the application field of the ship by the conventional accommodation ladder technology.
