Description

Technical Field

[0001] This application relates to the technical field of ships, and in particular to an embedded step for a high freeboard ship. Background Technology

[0002] The height of the upper edge of the deck of a high freeboard vessel is usually very large from the waterline, while the height of the land above the water at the dock is usually not very high. As a result, when a high freeboard vessel is docked, the height difference between the upper edge of the deck and the land at the dock is large, and additional gangways are required for personnel on board to go down to the dock or from the dock to the ship.

[0003] However, if an external gangway is installed directly on a ship, it will collide with the dock when the ship comes into contact with the dock, causing the external gangway to deform and become unusable, thus affecting the crew's boarding and disembarking.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In order to prevent the gangways installed on ships from being damaged during the process of the ship approaching the dock, this application provides an embedded step for ships with high freeboard.

[0006] This application provides a high-freeboard ship embedded upper and lower steps, which adopts the following technical solution:

[0007] A high freeboard ship embedded step includes a staircase embedded in the ship. One end of the staircase near the ship's hull is set below the deck, and the other end of the staircase is flush with the upper edge of the deck. The staircase is also provided with a gangway for docking with the dock. The shape of the gangway is the same as the bending shape of the staircase and is set to fit the surface of the staircase.

[0008] By adopting the above technical solution, the stairs are embedded inside the ship, so that the stairs will not directly collide with the dock during the ship's docking process, thus making the stairs less prone to damage. Furthermore, when the ship is far from the dock, the gangplank attached to the stairs can be moved to the lower end of the stairs between the stairs and the dock, allowing the ship to move from the stairs to the dock via the gangplank.

[0009] Optionally: The lower end of the scaffolding is rotatably connected to the lower end of the staircase.

[0010] By adopting the above technical solution, after one end of the gangplank is fixed to the stairs, when the gangplank is rotated toward the dock and one end of the gangplank is placed against the dock, the position of the end of the gangplank near the stairs is not easily changed, so that the gangplank can be stably connected to the ship and the gangplank is not easy to fall off.

[0011] Optional: The surface of the scaffold has several drainage holes.

[0012] By adopting the above technical solution, during ship navigation, when water falls onto the gangplank surface, it drips down through the drain holes and onto the stairs, then flows down the stairs, making it easier for water to adhere to the gangplank. This reduces the likelihood of crew slipping on the gangplank when using it and crossing it. The drain holes also increase friction between the crew and the gangplank, making it less likely for the ship to fall off. In addition to drainage, sunlight can also shine through the drain holes onto the stairs, causing water to evaporate quickly and further reducing the amount of water adhering to the stairs.

[0013] Optionally: Reinforcing rods are provided on both sides of the scaffolding, and the reinforcing rods are provided on the side wall of the scaffolding away from the stairs.

[0014] By adopting the above technical solution, when the gangplank is erected between the stairs and the dock, the gangplank can be supported from below by the reinforcing rods, so that the gangplank is not prone to downward deformation due to force when the crew passes over it, and the gangplank can stably support the crew's passage.

[0015] Optionally: The springboard is provided with a pushing assembly for rotating it. The pushing assembly includes a sleeve rotatably connected to one end of the springboard away from its own axis of rotation, and a pushing rod connected to the sleeve. The pushing rod passes through the sleeve and one end of the pushing rod is threaded into the sleeve. The pushing rod can pass through the reinforcing rod and is threaded into the reinforcing rod.

[0016] By adopting the above technical solution, the force is applied to the gangplank using a push rod, thereby moving the gangplank in the direction of the applied force. This eliminates the need to walk along the stairs and push the gangplank to rotate, making the gangplank rotation more convenient. Furthermore, when retracting the gangplank towards the stairs, there is no need to rotate the gangplank towards the ship on the dock, making the retraction of the gangplank more convenient.

[0017] Optionally: The springboard is provided with a sliding rod, which is arranged parallel to the rotation axis of the springboard itself, and the sleeve is rotatably connected to the sliding rod and can slide along the axis of the sliding rod.

[0018] By adopting the above technical solution, when there is no need to move the scaffold, the sleeve can be moved toward the side wall of the scaffold, so that the sleeve is no longer located in the middle of the scaffold, making it less likely for crew members to be affected by the sleeve when walking up and down the scaffold that is attached to the stairs.

[0019] Optionally, the threaded end of the push rod is also coaxially fixed with a handle.

[0020] By adopting the above technical solution, after the push rod is moved toward the reinforcement rod, the push rod can be rotated by applying force to the handle, making the connection between the push rod and the reinforcement rod more convenient.

[0021] Optionally, the staircase is further provided with a limiting member that restricts the rotation of the plank, and the lower end of the limiting member can abut against the side wall of the push rod that passes through the reinforcing rod away from the staircase.

[0022] By adopting the above technical solution, after the scaffolding is attached to the stairs, the lower end of the push rod can be abutted against the limiting component, thereby using the limiting component to restrict the position of the push rod, so that the scaffolding can be stably attached to the surface of the stairs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The staircase is embedded inside the ship, so that the staircase will not collide directly with the dock during the ship's docking process, thus making the staircase less prone to damage. In addition, when the ship is far from the dock, the gangplank attached to the staircase can be moved between the lower end of the staircase and the dock, so that the ship can be moved from the staircase to the dock by the gangplank.

[0025] 2. By using a push rod to apply force to the gangplank, the gangplank is moved in the direction of the applied force, thus eliminating the need to walk along the stairs and push the gangplank to rotate, making the gangplank rotation more convenient. Furthermore, when retracting the gangplank towards the stairs, there is no need to rotate the gangplank towards the ship on the dock, making the retraction of the gangplank more convenient.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an embedded upper and lower step for a high freeboard vessel, such as Figure 1 As shown, the system includes a staircase 1 embedded within the vessel. The staircase 1 is located at the stern of the vessel, with one side wall of the staircase 1 fitting flush with the side wall of a recessed area on the vessel's stern. The other side wall of the staircase 1 is flush with the stern plane of the vessel. One end of the staircase 1 is positioned near the hull and below the upper edge of the deck, while the other end is flush with the upper edge of the deck. A railing is installed on the upper surface of the staircase 1 near the stern of the vessel, and the upper end of the railing connects to a railing on the vessel's deck.

[0033] like Figure 1 and Figure 2 As shown, the staircase 1 is also equipped with a gangplank 2 for connecting the staircase 1 to the dock. The shape of the gangplank 2 is the same as the curved shape of the staircase 1, so that the gangplank 2 can fit against the surface of the staircase 1 when placed on it. The lower end of the gangplank 2 extends horizontally away from the lower end of the staircase 1 and is rotatably connected to the staircase 1. When the gangplank 2 is needed, by rotating the end of the gangplank 2 near the upper end of the staircase 1 away from the ship, one end of the gangplank 2 can abut against the bottom horizontal step of the staircase 1, and the other end of the gangplank 2 can be placed on the dock. After the ship docks, the gangplank 2 can be used to cross the space between the ship and the dock. When the gangplank 2 is not needed, it can also be placed directly on the staircase 1, allowing movement along the staircase 1 by stepping on the gangplank 2.

[0034] During navigation, water splashes onto gangway 2, reducing its surface friction and posing a safety hazard to crew members crossing it. Therefore, gangway 2 has several drainage holes 21. These holes allow liquid to flow downwards, preventing accumulation on the gangway 2 surface. Furthermore, the drainage holes increase friction between the gangway 2 and the soles of the crew's shoes, reducing the risk of slipping.

[0035] Since the scaffolding 2 has the same bend shape as the staircase 1, when the scaffolding 2 is placed between the staircase 1 and the dock, the middle of the scaffolding 2 is prone to deformation when crew members step on it, affecting its support for the crew. Therefore, two reinforcing rods 22 are installed on the side wall of the scaffolding 2 away from the staircase 1 it is attached to. The reinforcing rods 22 are parallel to the length direction of the scaffolding 2 and are respectively located close to the two side walls of the scaffolding 2 along its length. The reinforcing rods 22 are welded and fixed to the bend of the scaffolding 2, so that when the scaffolding 2 is erected between the staircase 1 and the dock, the reinforcing rods 22 are located below the scaffolding 2. When the scaffolding 2 is under stress, the reinforcing rods 22 can provide support, preventing the shape of the scaffolding 2 from changing, thus allowing the scaffolding 2 to stably support the crew members passing above it.

[0036] like Figure 3 As shown, since moving the scaffold 2 from the dock towards the stairs 1 requires assistance from people on the dock, making its movement difficult, a pushing assembly 3 is provided on the scaffold 2 to rotate it. The pushing assembly 3 includes a sleeve 31 rotatably connected to the scaffold 2 and a pushing rod 32 for moving the scaffold 2. The sleeve 31 is located at the end of the scaffold 2 away from the axis of rotation and has threads inside. The pushing rod 32 can pass through the sleeve 31, and one end of the pushing rod 32 has threads that engage with the threads inside the sleeve 31. The threaded engagement between the pushing rod 32 and the sleeve 31 allows the pushing rod 32 to connect with the sleeve 31, thereby applying force to the end of the scaffold 2, causing it to rotate towards the stairs 1 or push it away from the stairs 1, thus achieving the overlap of the scaffold 2 with the dock or the contact between the scaffold 2 and the surface of the stairs 1.

[0037] A sliding rod 23 is installed at the end of the scaffold 2 away from its own axis of rotation. The sliding rod 23 is located on the side of the scaffold 2 away from the stair 1. An extension block 311 is provided on the sleeve 31, located on the side of the sleeve 31 close to the sliding rod 23. The sliding rod 23 passes through the extension block 311, allowing the sleeve 31 to slide horizontally along the sliding rod 23 and to rotate to the side of the scaffold 2 closest to the stair 1. After the scaffold 2 is attached to the stair 1, the sleeve 31 can be moved toward the side wall of the scaffold 2, preventing the sleeve 31 from being placed directly in the middle of the scaffold 2 and making it less obstructive during normal ascent and descent of the stair 1.

[0038] The reinforcing rod 22 is hollow, with an open end away from the rotation axis of the springboard 2. The pushing rod 32 can be inserted into the reinforcing rod 22, and the thread on the pushing rod 32 engages with the thread at the opening of the reinforcing rod 22, allowing the pushing rod 32 to be stably inserted into the reinforcing rod 22. A handle 33 is coaxially fixed to the end of the pushing rod 32 extending from the reinforcing rod 22. The diameter of the handle 33 is larger than the inner diameter of the reinforcing rod 22. After inserting the pushing rod 32 into the reinforcing rod 22, gripping the handle 33 applies force to the pushing rod 32, causing it to rotate relative to the reinforcing rod 22. This achieves the threaded engagement between the pushing rod 32 and the reinforcing rod 22, and the handle 33 also limits the distance the pushing rod 32 can be inserted into the reinforcing rod 22.

[0039] like Figure 4As shown, during ship navigation, the ship will sway under the push of waves, and this swaying will cause vibration of the gangplank 2, resulting in the gangplank 2 moving relative to the staircase 1 and continuously colliding with the staircase 1. Therefore, a limiting member 11 is also provided on the staircase 1 to restrict the movement of the gangplank 2. The limiting member 11 is located near the side of the gangplank 2. The limiting member 11 is parallel to the sliding rod 23, and the lower end of the limiting member 11 can abut against the side wall of the push rod 32 that passes through the reinforcing rod 22 away from the staircase 1. Thus, the limiting member 11 is used to limit the position of the gangplank 2 relative to the staircase 1. When it is necessary to rotate the gangplank 2, the rotation of the gangplank 2 can be prevented from being affected by removing the push rod 32 from the reinforcing rod.

[0040] The implementation principle of this embodiment is as follows: When the distance between the ship and the dock is relatively close, the passenger can walk directly from the gangplank 2 attached to the stairs 1 to the dock. When the distance between the dock and the ship is relatively far, the handle 33 is turned to separate the push rod 32 from the threaded connection of the reinforcing rod 22. Then, the push rod 32 is moved along the axial direction of the reinforcing rod 22 and removed from the reinforcing rod 22. Then, the sleeve 31 is slid horizontally to the middle of the sliding rod 23. The end of the push rod 32 away from the handle 33 is inserted into the sleeve 31 from the end of the sleeve 31 away from the stairs 1. The push rod 32 is threaded to the sleeve 31. Then, force is applied to the end of the push rod 32 away from the sleeve 31 to push the gangplank 2 away from the stairs 1. When the gangplank 2 comes into contact with the dock, the push rod 32 is separated from the sleeve 31 and the push rod 32 is inserted into the reinforcing rod 22 and threaded to the reinforcing rod 22.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
