Description

Technical Field

[0001] The utility model relates to the technical field of ship boarding and disembarking facilities, and particularly relates to a boarding and disembarking facility applicable to ships with low freeboards. Background Art

[0002] When personnel need to board or disembark a ship at sea, a gangway device or a Jacob's ladder is usually used.

[0003] The gangway device is relatively complex and needs to be deployed through a mechanical device during use. When the freeboard of the ship is very low, it is not economical to use the gangway for boarding.

[0004] When boarding by hanging a Jacob's ladder on the ship's side, there is a risk that personnel may be collided by a traffic boat and fall into the water.

[0005] Therefore, providing a boarding facility with a simple structure and low boarding risk is an urgent problem to be solved in this field. Summary of the Utility Model

[0006] Aiming at the above technical problems existing in the existing boarding and disembarking facilities, the purpose of the utility model is to provide a boarding and disembarking facility for ships with low freeboards, which has a simple overall structure and can reduce the boarding risk by being embedded in the ship's side to form a fixed permanent passage.

[0007] To achieve the above purpose, the boarding and disembarking facility for ships with low freeboards provided by the utility model includes a structural ladderway. The structural ladderway is embedded in the ship's side. One end of the structural ladderway is located at the ship's side to form a first boarding opening, and the other end is connected to the deck to form a second boarding opening, thereby forming a passage from the ship's side to the deck.

[0008] Further, the structural ladderway is composed of a ramp, two groups of guardrail groups, and a tread group;

[0009] The ramp is composed of a connected flat section and an inclined section. The flat section is embedded in the ship's side and forms a first boarding opening. The inclined section is embedded in the ship's side and is connected to the deck, thereby forming a second boarding opening. The tread group is arranged on the inclined section, and the two groups of guardrail groups are symmetrically arranged on the inclined section and are located on both sides of the tread group.

[0010] Further, the flat section is parallel to the horizontal plane, and the inclined section has an inclination angle of 45 degrees relative to the horizontal direction.

[0011] Further, the first boarding opening and the second boarding opening are within a quarter range of the deck length.

[0012] Further, the tread group is composed of a plurality of treads. The plurality of treads are sequentially and equidistantly distributed along the length direction of the inclined section. The plurality of treads are all parallel to the horizontal plane and one end of each tread is connected to the inclined section.

[0013] Further, a number of openings are provided on the pedal.

[0014] Further, a reinforcing plate is connected to the bottom of the pedal. The reinforcing plate is respectively connected to the bottom of the pedal and the ramp, and can support the pedal.

[0015] Further, one end of the pedal is connected to the ramp, and the other end extends downward and towards the ramp to form a connecting plate.

[0028] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0029] See Figures 1 - 4 , which shows a schematic structural diagram of the boarding and disembarking facility for a low-freeboard ship provided by the present utility model.

[0030] According to the illustration, it can be seen that the boarding and disembarking facility for a low-freeboard ship provided by the present utility model includes a structural staircase 100 as a component.

[0031] The structural staircase 100 is embedded in the side 20. One end of the structural staircase 100 is located at the side 20 to form a first boarding entrance 140, and the other end is connected to the deck 10 to form a second boarding entrance 150, thereby forming a passage from the side 20 to the deck 10.

[0032] From the perspective of the side of the ship ( Figure 1 ), the structural staircase 100 forms a concave space in the side 20. The concave space is concave with respect to the side 20. The top of the concave space is exposed, and the bottom is a flat path 111 and a ramp 112; one side is the hull, and the other side is exposed on the side 20. The bottom flat path 111 and ramp 112 also serve as the hull structure. Personnel enter through the first boarding entrance 140, walk on the step group 130, reach the second boarding entrance 150, and finally reach the deck 10 to complete boarding.

[0033] The boarding and disembarking facility provided by the present utility model has a simple overall structure and is easy to implement. By being embedded in the side 20, a fixed permanent passage is formed, and there are no restrictive conditions during use (such as power failure of the ship, strong winds and waves, etc.). When personnel are waiting at the boarding entrance for boarding and disembarking, since it is embedded in the hull, they can be protected by the hull. When the tender sways and impacts the mother ship in strong winds and waves, it will not collide with the boarding personnel, reducing the boarding risk.

[0034] Specifically, as Figure 1 , the structural staircase 100 is composed of a ramp 110, two groups of guardrail groups 120, and a step group 130;

[0035] The ramp 110 is composed of a connected flat path 111 and a ramp 112. The flat path 111 is embedded in the side 20 to form a first boarding entrance 140, and the ramp 112 is embedded in the side 20 and connected to the deck 10 to form a second boarding entrance 150;

[0036] The step group 130 is arranged on the ramp 112 and is used for people to walk in a stepped manner.

[0037] Two groups of guardrail groups 120 are symmetrically arranged on the ramp 112 and on both sides of the step group 130 respectively, and are used to play a protective role when people walk on the step group 130.

[0038] Based on the above structure, when people board the ship, they first step onto the flat path 111 located on the side 20 of the ship's side on the shore and stand on the flat path 111, and then climb up the step group 130 on the ramp 112 in a stepped manner to the deck 10 to complete boarding. When leaving the ship, the situation is the opposite and will not be elaborated here.

[0039] Furthermore, the flat path 111 is parallel to the horizontal plane, so that people can stand better. The inclination angle of the ramp 112 relative to the horizontal direction is preferably 45 degrees, and this angle is the most comfortable angle for people to climb.

[0040] In this solution, the first boarding opening 140 and the second boarding opening 150 are within a quarter of the length of the deck 10. Since the first boarding opening 140 and the second boarding opening 150 need to open on the side 20 of the ship's side, when the opening of the side shell is within a quarter of the ship's length range from the bow or the stern, the influence on the longitudinal strength of the hull is relatively small.

[0041] Such as Figure 5 , the step group 130 is composed of a number of treads 131. The number of treads 131 are evenly distributed at equal intervals along the length direction of the ramp 112. The number of treads 131 are all parallel to the horizontal plane and one end is connected to the ramp 112. In this way, people can walk along the number of treads 131 to board and leave the ship.

[0042] A number of openings 131a are provided on the tread 131 for discharging seawater.

[0043] Such as Figure 6 , in order to further improve the reliability of the tread 131 on the ramp 112, a reinforcing plate 132 is connected to the bottom of the tread 131. The reinforcing plate is respectively connected to the bottom of the tread 131 and the ramp 112, and can support the tread 131.

[0044] Specifically, one end of the tread 131 is connected to the ramp 112, and the other end extends downward and towards the ramp 112 to form a connecting plate 133. An angular groove is formed between the connecting plate 133 and the tread 131. An angular groove is formed between the tread 131 and the ramp 112. The reinforcing plate 132 is triangular. One surface of the reinforcing plate 132 supports on the bottom of the tread 131, and an adjacent surface of this surface supports on the ramp 112 and the angular parts at both ends of this surface are respectively placed in the angular groove between the connecting plate 133 and the tread 131 and the angular groove between the tread 131 and the ramp 112;

[0045] The above structural design can greatly improve the reliability of the pedal 131 disposed on the ramp 112.

[0046] This solution does not limit the connection manner between the reinforcing plate 132, the pedal 131 and the ramp 112, which can be determined according to actual requirements. By way of example, welding or bolt connection can be adopted.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
