Description

FULLY- AUTOMATIC FOLDED REVOLVING GANGWAY FOR SHIPS
TECHNICAL FIELD
[01] The present invention relates to the technical field of ships, and more particularly to a fully-automatic folding rotatory gangway for ships.
BACKGROUND ART
[02] A gangway is an important tool for offshore platforms or ships, which can be used for transporting and transferring people or cargo between offshore platforms. For example, offshore wind turbine service personnel are required to land from the operational maintenance ship to the wind turbine foundation platform by means of gangways. Therefore, the gangway has become a necessary device for large and medium-sized ships, which is an important access for navigators to boarding when the matching ship enters the port. When the ship starts to sail, the gangway must be accommodated on the deck. In order to reduce the accommodation space of the gangway, the manufacturer designs the gangway as a two-section telescopic structure, i.e. the lower gangway and the upper gangway are sleeved coaxially, and when the gangway is deployed, the lower gangway is extended from the upper gangway by gravity or steel cable traction. The axial telescopic structure is simple, compact, extendable and retractable, which can significantly reduce the length dimension of the gangway, and can meet the matching requirements of tankers, bulk carriers and other ships. However, as the container ship and the large-sized cruise ship have many supporting facilities on the deck, there is not much room on the deck of the ship, and the accommodation place for the gangway is limited. If the two-section telescopic gangway of the prior art is still selected, on the one hand, it is difficult for the manufacturer to mount it, and on the other hand, it is inconvenient for the ship to use in the future.
[03] With the development of shipbuilding industry, a single gangway used on ships is far from meeting the demand. Therefore, the shipbuilding industry around the world has made a lot of research and improvement on the types and structures of gangway, and created some gangway devices which are easy to use, flexible to operate, economical, durable, safe and reliable. The two-piece telescopic gangway has correspondingly replaced both the roll-over and single-piece gangway arrangements of the past.
[04] CN 105460170 A relates to an automatic telescopic gangway for ships, which comprises a secondary gangway, a telescopic drive, a lifting winch and a control system, wherein the secondary gangway comprises an upper gangway and a lower gangway, the top end of the upper gangway is hinged to an upper platform of a hull via a shaft pin, the upper gangway and the lower gangway are connected via a sliding rail, the telescopic drive is mounted between the upper gangway and the lower gangway, the lifting winch is connected to the end of the lower gangway after passing through a pulley turning transition, and the control system comprises a shaft pin type tension sensor mounted on a pulley, an angle detection sensor mounted on the top end of the upper gangway and a
PLC controller which transmits electric signals with the tension sensor, the angle detection sensor, the telescopic driving device and the hoisting winch.
[05] CN 104417718 A discloses an automatic telescopic turnover gangway mounted on a hull, which comprises: a telescopic gangway, wherein the telescopic gangway comprises an upper platform frame hinged on a side deck, an upper platform turntable is rotatably mounted on the upper platform frame, an upper gangway is hinged on the upper platform turntable, and a lower gangway is slidably mounted on the upper gangway; a telescopic driving device provided between the hull and the telescopic gangway; a turning device comprising a vertical column, a turning arm being hinged to the hull, and a rotation locking device being provided between the turning arm and the vertical column; a turnover driving device provided between the turnover device and the telescopic gangway.
[06] In view of the above, the current development of gangway technology has greatly improved the difficulty of mounting, inconvenience of use and poor security of conventional bulk carriers, container ships and large cruise ships, but the above gangway patents still have some defects in the application process of gangway. For example, current telescopic or adjustable gangways, while being versatile, easy to operate, and space efficient, are also relatively complex in construction and still need to occupy some place for space within the deck or cabin due to mounting on the side or deck. Moreover, despite the ease of telescopic, the deployment process requires the assistance of hoisting equipment, which still requires the mounting of such auxiliary operating equipment for the vessel, which is cumbersome to operate, and the telescopic gangway structure, despite solving the ease of telescopic, in fact occupies a relatively large space. However, although the gangway mounted on the port does not occupy the space of the ship's side deck, and has a relatively complete function and a relatively high degree of automation, the gangway position needs to be considered when the ship stops at the port, and considering that the ship needs to stop at the port corresponds to the gangway position at the port, it is also a relatively difficult problem to control. Therefore, how to minimize the space occupied by the deck, mount it at the side of the ship, and realize the functions of fully-automatic retraction, folding, expansion and so on, has become an urgent technical problem to be solved in the field of ship application.
