AI Technical Summary
When the hinged arm springboard is retracted and placed, the transition overlap between the springboard and the deck is unstable, and the existing overlapping board has a low bearing capacity, which may cause safety accidents.
A marine lap board structure is designed, in which both ends of the springboard are connected to the hull hinge through support arms. The lap board includes a limiting plate. The limiting plate is arranged on the side of the lap board close to the springboard to limit the rotation of the lap board and ensure that the overlapping between the springboard and the deck is stable when retracted and placed.
Through this lap board structure, the lap board rotates to the deck and the springboard when the springboard is closed, resulting in damage, and improves loading and unloading capabilities, ensures high load-bearing capacity, and reduces the risk of safety accidents.

Abstract
Description
Technical Field
[0001] The utility model relates to a ship lap plate structure, in particular to a ship lap plate structure suitable for a hinged arm type gangway, and belongs to the field of ship design. Background Art
[0002] When a ship equipped with a gangway lowers the gangway, due to the presence of the gangway hinge, there will be a large gap in the transition section between the gangway and the deck after it is lowered, which may cause the wheels of the loading and unloading vehicles to get stuck, thus causing safety accidents. Therefore, ship lap plates came into being.
[0003] The hinge of the conventional lap plate is installed at the end of the deck near the gangway, and the lap plate is lapped on the gangway and can rotate freely along the hinge. When the hinge of the gangway is in the form of a hinge arm, the position of the center line of the hinge axis of the gangway hinge is different from the center line of the conventional hinge, and it will be raised away from the deck surface and the gangway. As a result, when the gangway is folded, due to the increase in the distance between the center line of the gangway hinge and the lap plate, the rear end of the gangway will be away from the deck, and the lap plate will be separated from the gangway and suspended in the air, and cannot be normally lapped and used. Summary of the invention

[0006] Preferably, the lap plate comprises a plurality of ribs, a panel is fixedly connected to the plurality of ribs, and a plurality of anti-slip strips are provided on the panel.
[0007] Preferably, the plurality of ribs are arranged along the width direction of the springboard.

[0010] Preferably, the lap plate is hinged to one end of the gangway close to the hull through an eye plate.
[0011] Preferably, the outer end of each rib is connected with a ball head.
[0012] Preferably, the ball head, anti-slip strip and springboard are all made of aluminum.
[0013] Preferably, the limiting plate is fixed below the overlapping plate.

[0022] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0023] The utility model proposes a ship lap plate structure, such as Figure 1-Figure 4 As shown, it includes a lap plate 2, one side of the lap plate 2 is connected to one side of the springboard 3 (i.e. the rear end of the springboard 3, located at Figure 1 The middle position of the left side position of the middle springboard 3) is hinged, and the two ends of the springboard 3 (i.e. Figure 1The upper and lower ends of the middle gangplank 3 are respectively hingedly connected to the hull 1 through two supporting arms 4, and the other side of the lap plate 2 is lapped on the hull 1.
[0024] The lap plate 2 is mainly composed of a rib plate 22, a panel 21, a ball head 25, an eye plate 24, a limit plate 26 and an anti-slip strip 23. The multiple rib plates 22 of the lap plate 2 are arranged along the width direction of the springboard 3. The aluminum ball head 25 is welded to the outer end of the rib plate 22. The panel 21 is installed above the rib plate 22. A plurality of aluminum anti-slip strips 23 are welded on the panel 21. The length direction of the plurality of anti-slip strips 23 is consistent with the width direction of the springboard 3. An eye plate 24 is welded on one side of the panel 21 close to the springboard 3. The eye plate 24 on the panel 21 is connected to the welding plate through the lap plate axis. The eye plate 24 connected to the corresponding position of the gangway 3 is rotatably connected (that is, the lap plate shaft is inserted into the eye plate 24 on the panel 21 and the eye plate 24 on the gangway 3), and a limit plate 26 is provided under the lap plate 2 for limiting the rotation of the lap plate 2, so that when the gangway 3 is retracted (that is, from the gangway opening state B to the gangway closing state A), the other end of the limit plate 26 is placed (or abutted) on the end surface of one side of the gangway 3, so as to prevent the lap plate 2 from rotating to the space between the deck and the gangway 3 when the gangway 3 is retracted, and the lap plate is squeezed and damaged after the gangway is lowered. Figure 4 The eye plate 24 of the springboard 3 is arranged on the end plate at the rear end of the springboard 3; the limit plate 26 is respectively connected to the bottom of the panel 21 and the end of the rib plate 22 at the location (the end close to the springboard 3).
[0025] The lap plate 2 is welded and installed on the end of the aluminum ramp 3 close to the hull 1 through the eye plate 24. After the ramp 3 is opened to the right position (i.e., when the ramp is in the open state B), the lap plate 2 is placed on the hull 1. Figure 1 As shown, at this time, there is a gap between the other end of the limiting plate 26 and the end surface of one side of the springboard 3 (or there may be no gap, that is, they are still in contact).
