[0039] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0040] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0041] This utility model provides a ship gangway telescopic adjustment device with integrated spring damping, including: hull 1 and buffer assembly 3;

[0042] A platform 101 is provided on one side of the hull 1. A guardrail 1011 is fixedly connected to the outer side of the platform 101. A buffer assembly 3 is provided at the bottom of the platform 101. The buffer assembly 3 includes the following components:

[0043] Connecting vertical rod 301: It is fixedly connected to the middle of the bottom of the platform 101. One end of the connecting vertical rod 301 is fixedly connected to the reinforcing corner seat 3011, and the other end of the connecting vertical rod 301 is fixedly connected to the connecting carrier tube 3012. The outer side of the connecting carrier tube 3012 is fixedly connected to the fixing outer ring 3013.

[0044] Sliding support hole 302: It is opened inside the connecting carrier cylinder 3012. A movable sliding column 3021 is slidably installed inside the sliding support hole 302. One end of the movable sliding column 3021 is fixedly connected to the limiting cam 3022. The connecting carrier cylinder 3012 is also provided with a buffer chamber 3023. The inner side wall of the buffer chamber 3023 is in contact with the outer side wall of the limiting cam 3022. A second spring 3024 is provided inside the buffer chamber 3023.

[0046] When the ship sways due to waves, currents, or other factors, the swaying force causes the buffer seat 3025 to contact the dock. The buffer seat 3025 then compresses the second spring 3024 in the buffer chamber 3023 via the movable sliding column 3021, allowing it to absorb some of the energy generated by the swaying. Then, under the action of the damper 303, a corresponding damping force is generated, further consuming energy and reducing the swaying amplitude of the ship's ladder.

[0047] Example 2: Based on Example 1, wherein... Figures 2 to 5As shown, the bottom of the platform 101 is provided with an adjustment component 2. The adjustment component 2 includes a connecting hinge block 201, a fixed hinge frame 2011, a pin 2012 and a gear 2013. The connecting hinge block 201 is fixedly connected to one end of the bottom of the platform 101. The connecting hinge block 201 is hinged to the fixed hinge frame 2011 through the pin 2012. The gear 2013 is fixedly connected to one end of the pin 2012.

[0048] One end of the fixed hinge 2011 is fixedly connected to a connecting support block 202. A main gangway 2021 is provided between the connecting support blocks 202. The main gangway 2021 has a moving groove 2022 inside. A drive motor 203 is fixedly installed inside one side of the connecting support block 202. The drive end of the drive motor 203 is fixedly connected to a lead screw 2031. The other end of the lead screw 2031 is rotatably installed in another set of connecting support blocks 202. At the same time, a guide rod 2032 is provided on the opposite side of the lead screw 2031.

[0049] The movable channel 2022 is provided with a movable belt block 204. The two ends of the movable belt block 204 are respectively provided with threaded holes 2041 and guide holes 2042. A secondary gangway 2043 is fixedly connected to one side of the movable belt block 204.

[0050] A connecting plate 205 is fixedly connected to one side of the platform 101. A limiting protrusion 2051 is fixedly connected to the top of the connecting plate 205. A first spring 2052 is provided on the outside of the limiting protrusion 2051.

[0051] The bottom of the connecting convex plate 205 is provided with a locking tooth plate 206, which meshes with the gear 2013. Both ends of the locking tooth plate 206 are fixedly connected with an extension arc plate 2061, and the connecting convex plate 205 is provided with a movable sliding hole 2062. The top of the extension arc plate 2061 is fixedly connected with a pull rod 2063, which is slidably installed in the movable sliding hole 2062. At the same time, a centralized sliding sleeve 2064 is fixedly connected between the pull rods 2063, and the centralized sliding sleeve 2064 is located on the outside of the limiting convex post 2051.

[0052] The pivot pin 2012 is fixedly connected to the fixed hinge 2011. During adjustment, pulling the lever 2063 causes the locking gear 206 to move upwards, releasing the lock on the gear 2013. This allows for angle adjustment of the fixed hinge 2011 via the pivot pin 2012, thereby adjusting the angle of the gangway to bring it closer to the dock. After adjustment, the lever 2063 is released. As the lever 2063 moves, it compresses the first spring 2052 through the concentrated sliding sleeve 2064, causing the first spring 2052 to become elastic. Under the action of this elasticity, the first spring 2052... It pushes the locking tooth plate 206 to reset, so that it is locked on the gear 2013, thereby locking the angle of the gangway. By starting the drive motor 203, the lead screw 2031 is driven to rotate. The lead screw 2031 engages with the threaded hole 2041 on the moving belt block 204. However, the other end of the moving belt block 204 is guided at the upper limit of the guide rod 2032 through the guide hole 2042, so that the lead screw 2031 drives the moving belt block 204 to move. The moving belt block 204 then drives the auxiliary gangway 2043 to extend out from the moving groove 2022, thereby extending the length of the gangway.

[0053] The specific usage and function of this embodiment are as follows:

[0054] In this invention, the angle of the fixed hinge 2011 is adjusted by the pivot pin 2012, thereby adjusting the angle of the gangway. After adjustment, the pull rod 2063 is released. When the pull rod 2063 moves, it compresses the first spring 2052 through the concentrated sliding sleeve 2064, causing the first spring 2052 to become elastic. Under the action of elasticity, it pushes the locking tooth plate 206 to reset, locking it onto the gear 2013, thus locking the angle of the gangway. By starting the drive motor 203, the lead screw 2031 is driven to rotate. The lead screw 2031 meshes with the threaded hole 2041 on the moving belt block 204. However, the other end of the moving belt block 204 is guided at the upper limit of the guide rod 2032 through the guide hole 2042, so that the lead screw 2031 drives the moving belt block 204 to rotate. The moving belt block 204 moves, which in turn drives the auxiliary gangway 2043 to extend from the moving slot 2022, thereby extending the length of the gangway. This allows for precise adjustment of the gangway length and angle, adapting to different distances and height differences between ships and docks or platforms, thus improving the versatility and applicability of the gangway. When the ship sways due to waves, currents, or other factors, the force of the swaying causes the buffer seat 3025 to contact the dock. The buffer seat 3025 then drives the limiting cam 3022 through the movable sliding column 3021 to compress the second spring 3024 in the buffer chamber 3023, allowing it to absorb some of the energy generated by the swaying. Then, under the action of the damper 303, a corresponding damping force is generated, further consuming energy and reducing the swaying amplitude of the ship's gangway.
