Description

Technical Field

[0001] The utility model relates to the field of lifting type gangways, in particular to a lifting type gangway for ships. Background Art

[0002] Gangways are passage facilities between a ship and the outside world. Passenger ships should be equipped with gangways, and other types of large and medium-sized ships should also be equipped with gangways. Small boats generally do not have gangways. Gangways are generally arranged at the edge of the deck of the lowest side passage on both sides of the ship that is not enclosed by the hull outer plate. According to the size of the ship and usage needs, usually one gangway is set on each side. Large passenger ships should consider setting up two gangways on each side. When a gangway is set on each side of the ship, it should be located behind the midship of the ship, or near the superstructure, to facilitate people to get on and off the gangway.

[0003] After the existing gangway is connected to the hull, the hull may shake due to water fluctuations, thereby causing the gangway to shake. If there is no warning mechanism, the sudden shaking may increase the danger of getting on and off the gangway.

[0004] In order to solve the above problems, the present application proposes a lifting gangway for ships. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a lifting gangway for ships. The utility model is provided with a reminder mechanism to facilitate reminders and increase the safety and alertness of use.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a lifting gangway for a ship, comprising a gangway, one end of which is rotatably connected to a connecting plate via a rotating shaft;

[0009] The side of the connecting plate close to the hull is rotatably connected to a right-angle plate fixedly connected to the hull through a rotating shaft;

[0010] A reminder mechanism which responds to the rotation of the connecting plate is fixedly installed on the gangway.

[0011] Preferably, the reminder mechanism includes a sleeve, a mounting plate, a movable rod, a whistle and a spring, the sleeve is fixedly connected to the gangway through the mounting plate, one end of the movable rod slides into the interior of the sleeve and is connected to the closed end of the sleeve through the spring, and the air inlet of the whistle is fixedly connected to the sleeve.

[0012] Preferably, a rolling element is provided at one end of the moving rod located outside the sleeve.

[0013] Preferably, the rolling element is a ball or a roller.

[0014] Preferably, the gangway is connected to the traction machine via a connecting rope.

[0015] The above technical solution of the utility model has the following beneficial technical effects:

[0016] When the hull is shaking, the connecting plate is driven to move up and rotate, so as to drive the connecting plate to lift the moving rod. The movement of the moving rod squeezes the air inside the casing and discharges it through the whistle, which serves as a sounding reminder, thereby reminding the user of the shaking state, so as to increase the user's vigilance when using the gangway.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] like Figure 1-3 As shown, the utility model provides a ship lifting gangway, comprising a gangway 1, one end of which is rotatably connected to a connecting plate 2 via a rotating shaft;

[0023] The side of the connecting plate 2 close to the hull is rotatably connected to a right-angle plate 3 fixedly connected to the hull through a rotating shaft;

[0024] A reminder mechanism 4 is fixedly mounted on the gangway 1 and responds to the rotation of the connecting plate 2 .

[0025] In an optional embodiment, the reminder mechanism 4 includes a sleeve 41, a mounting plate 42, a movable rod 43, a whistle 44 and a spring 45. The sleeve 41 is fixedly connected to the gangway 1 through the mounting plate 42. One end of the movable rod 43 slides into the interior of the sleeve 41 and is connected to the closed end of the sleeve 41 through the spring 45. The air inlet of the whistle 44 is fixedly connected to the sleeve 41.

[0026] It should be noted that a piston is fixedly mounted on one end of the moving rod 43 inserted into the sleeve 41 .

[0027] In an optional embodiment, a rolling member 46 is provided at one end of the moving rod 43 located outside the sleeve 41 .

[0028] Specifically, the rolling element 46 is a ball or a roller.

[0029] When a ball bearing is used, the ball bearing is rotatably sleeved on the end of the moving rod 43;

[0030] When the roller is selected, the roller frame is fixedly connected to the moving rod 43.

[0031] It should be noted that, under the action of the rolling element 46 , the smoothness of the action on the moving rod 43 is increased when the connecting plate 2 is rotated and lifted.

[0032] In an optional embodiment, the gangway 1 is connected to a traction machine via a connecting rope 5, and the traction machine is fixedly connected to the hull.

[0033] It should be noted that the lifting gangway is a known technology and will not be described in detail here.

[0034] In the utility model, when the hull is shaking, the connecting plate 2 is driven to move upward, and the connecting plate 2 rotates to drive the connecting plate 2 to lift the moving rod 43. The movement of the moving rod 43 squeezes the air inside the sleeve 41 and discharges it through the whistle 44, which serves as a sounding reminder, thereby reminding the user of the shaking state, so as to increase the user's alertness when using the gangway 1.

[0035] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
