Description

Technical Field

[0001] The utility model relates to a novel gangway device. Background Art

[0002] Gangway devices are provided on various ships to allow people on foreign ships to board. Usually, the gangway device is placed behind the gangway door. After the gangway door is opened horizontally, the gangway device is turned down to form a ladder for people to board.

[0003] However, some longer gangway doors are not suitable for opening horizontally outwards because the extended length of the opened gangway door is too long, the center of gravity is far from the hinge between the gangway door and the door frame, and components such as the gangway device are likely to damage the gangway door. Therefore, the conventional gangway device is not applicable to such horizontally opened gangway doors. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above deficiencies and provide a novel gangway device that protects the gangway door and is safe and reliable.

[0005] The purpose of the utility model is achieved as follows:

[0006] A novel gangway device includes a door frame arranged on the side of the ship's hull. A gangway door is installed in the door frame. A plurality of hinge devices are arranged between the top of the gangway door and the door frame. Two column mechanisms are arranged at the rear side of the gangway door. Each column mechanism includes a column. A link mechanism is arranged on the back of the gangway door. The two ends of the link mechanism are respectively hinged to the column and the gangway door. A gangway device is arranged on the back of the gangway door. The gangway device includes a platform and a gangway. The front end of the gangway is hinged to the platform, and the gangway can be flipped. A lower pulley support plate is arranged at the lower half of the column. A lower pulley is arranged on the lower pulley support plate. An upper pulley is arranged at the upper half of the column. A rigging is sleeved at the end of a steel wire rope. After the steel wire rope bypasses the lower pulley and the upper pulley, it is respectively connected to the column and the platform.

[0007] The bottom of the column is reinforced with the ground through a rib plate.

[0008] Railings are arranged on both sides of the gangway.

[0009] The novel gangway device of the utility model has the following advantages:

[0010] By designing the gangway door to be opened at the top, the novel gangway device of the utility model avoids the problem of damaging the gangway door caused by too far a center of gravity. Moreover, the hinge device and the steel wire rope can play a buffering and protective role in the flipping of the gangway door and the gangway device, extending the service life of the gangway door.

[0015] In the figure: door frame 1, midship door 2, hinge device 3, column mechanism 4, column 4.1, rib plate 4.2, lower pulley support plate 4.3, lower pulley 4.4, upper pulley 4.5, steel wire rope 4.6, rigging 4.7, link mechanism 5, midship ladder device 6, platform 6.1, midship ladder 6.2, railing 6.3. Specific implementation manner

[0016] See Figures 1 to 4 , the present utility model relates to a new type of midship ladder device, including a door frame 1 provided on the side of the ship's hull. A midship door 2 is installed in the door frame 1. A plurality of hinge devices 3 are provided between the top of the midship door 2 and the door frame 1. The hinge devices 3 are used to limit the opening speed of the midship door 2 to avoid wear of the steel midship door.

[0017] Two column mechanisms 4 are provided at the rear side of the midship door 2. Each column mechanism 4 includes a column 4.1, and the bottom of the column 4.1 is fixed to the bottom surface of the cabin. A link mechanism 5 is provided on the back surface of the midship door 2, and both ends of the link mechanism 5 are respectively hinged to the column 4.1 and the midship door 2. The column 4.1 is fixed to the cabin. When the midship door 2 is opened outwards, the link mechanism 5 slowly extends, playing a guiding and buffering role.

[0018] A midship ladder device 6 is provided on the back surface of the midship door 2. The midship ladder device 6 includes a platform 6.1 and a midship ladder 6.2. The front end of the midship ladder 6.2 is hinged to the platform 6.1, and the midship ladder 6.2 can be flipped. Railings 6.3 are provided on both sides of the midship ladder 6.2.

[0019] The bottom of the column 4.1 is reinforced with the ground through a rib plate 4.2. A lower pulley support plate 4.3 is provided in the lower half of the column 4.1, and a lower pulley 4.4 is provided on the lower pulley support plate 4.3. An upper pulley 4.5 is provided in the upper half of the column 4.1. A rigging 4.7 is sleeved at the end of the steel wire rope 4.6. After the steel wire rope 4.6 bypasses the lower pulley 4.4 and the upper pulley 4.5, it is respectively connected to the column 4.1 and the platform 6.1. The midship ladder device 6 is slowly lowered through the steel wire rope 4.6, increasing the safety of the midship ladder device 6.
