Description

Technical Field

[0001] This invention relates to the field of ship installation equipment technology, specifically a modular mechanical installation structure for ship decks. Background Technology

[0002] Ship gangways are movable bridge-like passageways connecting ships to docks, other vessels, or offshore platforms. They are primarily used to ensure the safe boarding and disembarking of personnel and can also assist in the transfer of small amounts of lightweight supplies. They are indispensable key safety facilities during ship berthing. Their functionality directly affects the safety of crew, port staff, and passengers, and also impacts operational efficiency during ship berthing. They play an irreplaceable role in the daily operations of various types of vessels and serve as a crucial hub connecting ships with land and offshore platforms.

[0003] However, while ships are docked, they are continuously affected by natural environmental factors such as sea breezes, currents, and waves. Furthermore, the ebb and flow of tides cause the ship's hull to rise and fall, resulting in a dynamic height difference between the ship's deck and the dock. Because existing ship gangplanks often use a rigid, fixed contact method at the dock end, this rigid connection cannot adapt to the height changes caused by tidal rises and falls and wave rises and falls. This results in a persistent vertical height difference between the gangplank end and the dock, sometimes even momentarily causing it to be suspended in mid-air. Simultaneously, the hard compression between the two causes wear on the contact surface, which, over time, severely affects the overall lifespan of the gangplank and increases equipment maintenance costs.

[0004] Furthermore, ships experience horizontal displacement due to sea winds and currents. This horizontal displacement can cause tension, lateral slippage, and jamming between the gangway end and the dock, further exacerbating the overall swaying of the gangway. Continuous swaying not only affects the stability of personnel passage, increasing the risk of tripping and missteps, but also accelerates fatigue wear on the gangway structure, creating a vicious cycle of swaying-induced wear and reduced stability, thus failing to fully meet the safety requirements of complex maritime conditions. Therefore, those skilled in the art have proposed a modular mechanical installation structure for ship decks to address the aforementioned technical problems. Summary of the Invention

A sidewall rubber layer is provided in the middle of the two sidewalls of the slot.

[0013] Preferably, the plate stabilizing mechanism includes a high-viscosity damping liquid cavity. The high-viscosity damping liquid cavity is provided in the lower middle part of the inner side of the springboard.

A reset tension spring is provided at the middle of both ends of each horizontal guide cavity, and one end of each reset tension spring is connected to the middle of the counterweight slide. Rubber damping pads are provided on the upper and lower sides of the inner wall of the horizontal guide cavity.

[0015] Working principle: When a vessel is berthing, after the ship is anchored and secured, the control equipment drives the gangway on the hull below the boarding gate on the side of the ship to be lowered smoothly, creating a stable passage connection between the ship and the dock. After the gangway is reliably connected to the dock, the workers promptly install and connect safety railings on the gangway. The protective structure further ensures the overall safety of the gangway during subsequent personnel passage. Then, the floating support mechanism is activated. When tidal changes cause continuous vertical rise and fall of the ship's hull, or when waves cause momentary undulations in the hull... During heave and sway, due to the reasonable clearance between the limiting ball joint on the hull fixed seat and the floating cavity on the gangplank, when the ship's hull is displaced by the combined effects of tides and waves, the connecting spring on the connecting column at the bottom of the gangplank will adaptively expand and contract according to the height change of the support surface. Simultaneously, the connecting column will also synchronously drive the floating support seat and its bottom ball bearings to float up and down, thus offsetting the static height difference between the ship and the dock caused by tides and the dynamic height difference caused by wave rise and fall. Furthermore, when the connecting column moves downwards synchronously driven by the gangplank at its top, the connecting column... During the downward movement, the sealing and squeezing seat inside the reservoir cavity moves downward in tandem. As it moves downward, the sealing and squeezing seat continuously squeezes the buffer solution inside the reservoir cavity, allowing the liquid to be smoothly transported through a pre-set internal flow channel to the silicone reservoir bladder in the bottom cavity. As the silicone reservoir bladder is continuously filled with buffer solution, it undergoes controllable expansion deformation under liquid pressure. Throughout the entire process of the sealing and squeezing seat filling the silicone reservoir bladder with liquid, the squeezing and impact forces generated by the spring board during its up-and-down movement are buffered and neutralized through multiple mechanisms, including spring extension and contraction, liquid force transmission, and bladder expansion. The attenuation effectively reduces the impact of impact loads on the structure. During this process, the balls at the bottom of the floating support seat undergo a small-amplitude adaptive sliding under the action of the scaffold and the floating support seat, thereby adapting to the horizontal relative displacement between the hull and the dock. At the same time, with the assistance of the rubber layer on the bottom sidewall of the slotted section, the balls transform the sliding friction generated by the traditional rigid contact into low-resistance rolling friction. This avoids the problem of hard friction jamming between the bottom of the floating support seat and the dock, and effectively improves the fit and stability of the contact surface when the scaffold and the dock are in contact, thus completing the vertical floating support treatment of the scaffold during use.Simultaneously, the horizontal buffer mechanism activates. When tidal changes and wave impacts cause continuous horizontal swaying of the ship's hull, due to the reasonable fit between the limiting ball joint on the hull fixed seat and the floating cavity on the ramp, the swaying amplitude of the ramp itself is less than that of the hull fixed seat when the ship's hull sways under the influence of tides and waves. During the synchronous swaying and swinging process of the hull fixed seat and its mounting seat, the repulsive force between the same-pole magnetic seat in the mounting seat and the same-pole magnetic part on the side support rod will initially buffer the swaying impact load transmitted from the hull. Furthermore, the frictional resistance formed between the guide limiting protrusion on the side support rod and the mounting seat further dissipates the swaying impact load. The pendulum energy is used to maximize the buffering and weakening of the swaying force transmitted to the diving board. When the diving board sways under the action of horizontal swaying force, the floating support at the bottom of the board continuously compresses the rubber seat in the slot during the swaying process. When the rubber seat is squeezed by the swaying of the floating support, the air in its internal cavity is slowly discharged through the micropores on the microporous seat under pressure. In this process, the compression and discharge of air in the cavity initially buffers the swaying force of the diving board. After the cavity is completely compressed and closed, the elastic deformation of the rubber seat itself further buffers the swaying force of the diving board. At the same time, the side wall rubber layer in the slot provides flexible elastic buffering for the edge of the floating support at the bottom of the diving board, thus completing the buffering of the diving board's swaying force. Multiple buffering mechanisms are used to handle horizontal swaying forces during use. Simultaneously, the board stabilization mechanism activates. When the board experiences high-frequency, small-amplitude swaying, fluttering, or structural resonance due to continuous wave action, the omnidirectional inertial oscillating ball within the high-viscosity damping fluid cavity remains stationary relative to the surrounding space due to its own inertia. This creates a stable relative motion with the omnidirectional hinge rod that sways synchronously with the board and the high-viscosity damping fluid cavity. During this process, the high-viscosity damping fluid in the cavity generates a continuous and uniform reverse damping torque on the omnidirectional inertial oscillating ball, quickly absorbing and dissipating the board's swaying energy, effectively suppressing high-frequency vibrations and structural resonance, and preventing the continuous amplification of small-amplitude swaying. Furthermore, the elastic buffer seat within the high-viscosity damping fluid cavity effectively... The oscillation amplitude of the omnidirectional inertial oscillating ball is limited to prevent large-scale oscillations from causing structural impact, thereby achieving automatic leveling of the skid's tilt attitude and rapid suppression of small-amplitude swaying. This ensures that the skid remains stable and vibration-free in complex sea conditions, thus completing the anti-sway treatment of the skid during use. At the same time, the automatic balancing mechanism is activated. When the skid tilts to the left or right or sways to one side due to the influence of waves and tides during use, the counterweight slide in the horizontal guide cavity does not require external power drive. Under its own weight, it automatically slides along the horizontal guide cavity inside the skid to the lower side of the skid. The counterweight offset generates a reverse restoring torque opposite to the tilt direction, directly offsetting the tilting torque caused by the external environment.When the tilting load decreases, the return spring smoothly pulls the counterweight slide in the horizontal guide cavity back to its center, ensuring the plank's center of gravity remains close to its own central axis and maintaining overall stability. During this process, the rubber damping pads in the horizontal guide cavity effectively absorb the impact and high-frequency vibrations generated during the counterweight slide's movement, preventing the counterweight slide's own movement from exacerbating plank swaying. The entire process requires no external power or manual intervention, achieving real-time, passive, and automatic restoration of the plank's horizontal balance, thus completing the automatic adjustment and balancing process during plank use.

[0016] This invention provides a modular mechanical mounting structure for ship decks. It has the following advantages: 1. This invention, by adding and setting a floating support mechanism, enables the use of gangplanks by personnel when ships are docked. On the one hand, this mechanism can adapt to the height changes caused by tidal rise and fall and wave rise and fall. Through the extension and contraction of connecting springs and the expansion of silicone reservoirs, it effectively offsets the static and dynamic height differences between the ship and the shore, avoids the gangplank ends being suspended or hard-pressed, reduces wear on the contact surface, and extends the service life of the gangplank. On the other hand, it transforms rigid sliding friction into low-resistance rolling friction through ball bearings, adapting to the horizontal relative displacement between the ship and the dock, avoiding jamming, and improving the fit stability between the gangplank and the dock, providing stable support for personnel passage and reducing the vertical swaying effect from the source.

[0017] 2. By adding and setting a horizontal buffer mechanism, this invention can effectively buffer the horizontal swaying force transmitted from the ship to the gangplank when it is used by personnel at the dock. This mechanism can not only reduce the swaying amplitude by using the repulsive force between the same magnetic base and the same magnetic part, combined with the frictional resistance of the guide limit protrusion, but also prevent the gangplank from being pulled or slipped due to horizontal displacement. Furthermore, the horizontal swaying force of the gangplank is doubled by the compression and discharge of air in the cavity of the rubber base and the elastic deformation of the rubber itself. Combined with the flexible protection of the side wall rubber layer, the swaying energy is further dissipated, preventing the horizontal swaying from intensifying and ensuring the stability of the center of gravity when personnel walk, thus avoiding safety hazards caused by horizontal swaying.

[0018] 3. By adding and setting a board stabilizing mechanism, this invention addresses the high-frequency, small-amplitude swaying, fluttering, and structural resonance phenomena caused by waves when the board is used for personnel docking. It utilizes the reverse damping torque generated by a high-viscosity damping fluid on the omnidirectional inertial oscillating ball to quickly absorb and dissipate swaying energy, effectively suppressing the superposition and amplification of swaying and preventing severe board shaking. Secondly, the elastic buffer seat limits the swing amplitude of the omnidirectional inertial oscillating ball, preventing large-scale swinging from causing structural impact. Simultaneously, it automatically corrects the board's tilt posture, ensuring the board remains stable and vibration-free even in complex sea conditions. This provides a stable operating environment for personnel passage and material transfer, improving safety.

[0019] 4. By adding and setting an automatic balancing mechanism, this invention enables the use of the gangway by personnel when the ship is docked. Not only can it automatically counteract the tilting torque and achieve real-time restoration of horizontal posture without external power or manual intervention when the gangway tilts left or right or sways to one side, but it also allows the counterweight slide to slowly return to center via a reset spring, keeping the gangway's center of gravity close to the central axis. Combined with rubber damping pads to absorb slippage impacts and high-frequency vibrations, this prevents the counterweight movement from exacerbating swaying, completely solving the gangway tilting problem and further improving the overall stability and reliability of the gangway, making it suitable for various complex maritime conditions.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a modular mechanical installation structure for ship decks, including a dock 1, with a slot 9 on the top of the dock 1 near the hull; a hull fixing seat 3, which is connected to the lower part of the boarding gate on the side of the ship, and a ramp 5 for personnel and small cargo to move up and down on the hull fixing seat 3, with one end of the ramp 5 away from the hull fixing seat 3 extending onto the dock 1; and hinge connecting seats 6 for connecting articulated traction devices are fixedly connected to both sides of the hull fixing seat 3 near the dock 1. Please see the appendix Figure 4 -Appendix Figure 5 A floating support mechanism is located on one side of the bottom of the springboard 5 and is used to provide elastic support for the springboard 5 when it floats up and down in the face of waves or tides during use. The floating support mechanism includes a floating support base 10. The floating support base 10 is installed inside the slot 9. A liquid storage chamber 15 is opened in the middle of the inner side of the floating support base 10. A sealing squeeze seat 18 that can squeeze the liquid inside the liquid storage chamber 15 is installed inside. Multiple connecting columns 14 are fixedly connected at equal intervals on one side of the bottom of the springboard 5. The bottom of the connecting column 14 passes through the floating support base 10 and is connected to the corresponding position of the top of the sealing squeeze seat 18. A connecting spring 13 is installed on each connecting column 14.

[0024] When the floating support mechanism is activated, when tidal changes cause the ship's hull to experience continuous vertical rise and fall, or when wave impact causes the hull to experience instantaneous rise and fall, the limiting ball joint seat 19 on the hull fixed seat 3 and the floating cavity 7 on the gangway 5 have a reasonable fit gap. Therefore, when the ship's hull is displaced by the combined action of tides and waves, the connecting spring 13 on the connecting column 14 at the bottom of the gangway 5 will adaptively extend and retract according to the height change of the support surface. At the same time, the connecting column 14 will also synchronously drive the floating support seat 10 and the ball bearings 12 at its bottom to move up and down synchronously, thereby offsetting the static height difference between the ship and the dock 1 caused by tides and the dynamic drop caused by the rise and fall of waves.

[0025] The floating support mechanism also includes a bottom cavity 17. The bottom cavity 17 is provided on the inner bottom of the floating support seat 10. A silicone liquid storage bladder 16 is provided in the middle of the inner side of the bottom cavity 17. The interior of the silicone liquid storage bladder 16 is connected to the interior of the liquid storage cavity 15 through the internal flow channel in the floating support seat 10.

[0026] Simultaneously, when the connecting column 14 moves downward due to the synchronous drive of its top spring plate 5, the connecting column 14 will synchronously drive the sealing squeeze seat 18 in the liquid storage cavity 15 to move downward in the same way. When the sealing squeeze seat 18 moves downward, it will continuously squeeze the buffer solution inside the liquid storage cavity 15, so that the liquid in the liquid storage cavity 15 is smoothly transported to the silicone liquid storage bladder 16 in the bottom cavity 17 through the preset internal flow channel.

[0027] As the silicone reservoir 16 is continuously filled with buffer solution, it will undergo controllable expansion deformation under liquid pressure. During the entire process of the sealing squeeze seat 18 squeezing the liquid into the silicone reservoir 16, the squeezing and impact forces generated by the spring board 5 during its up-and-down floating will be buffered and attenuated through multiple methods such as spring extension and contraction, liquid force transmission, and bladder expansion, effectively reducing the impact of impact loads on the structure.

[0028] The floating support mechanism also includes a rubber base 29. The bottom of the slot 9 is provided with a rubber base 29. The bottom of the floating support seat 10 is provided with multiple balls 12 at equal intervals. Multiple floating cavities 7 are provided at equal intervals on the side of the gangway 5 near the hull fixing seat 3. Multiple limiting ball seats 19 are fixedly connected at equal intervals in the middle of the side of the gangway 3 near the gangway 5. The limiting ball seats 19 extend into the corresponding floating cavities 7. There is a gap between the inner wall of the floating cavity 7 and the limiting ball seat 19.

[0029] During this process, the ball bearings 12 at the bottom of the floating support seat 10 undergo a small-amplitude adaptive sliding under the influence of the gangway 5 and the floating support seat 10, thereby adapting to the horizontal relative displacement between the hull and the dock 1. At the same time, with the assistance of the rubber layer 11 on the bottom side wall of the slot 9, the ball bearings 12 transform the sliding friction generated by the traditional rigid contact into low-resistance rolling friction. This not only avoids the problem of hard friction jamming between the bottom of the floating support seat 10 and the dock 1, but also effectively improves the fit and stability of the contact surface when the gangway 5 contacts the dock 1, thus completing the vertical floating support treatment of the gangway 5 during use.

[0030] Please see the appendix Figure 3 and attached Figure 6 -Appendix Figure 7 A horizontal buffer mechanism is located at the bottom of the ramp 5 and is used to buffer the horizontal swing of the ramp 5 when it faces waves or tides during use. The horizontal buffer mechanism includes mounting bases 4. Multiple mounting bases 4 are rotatably connected at equal intervals on the side of the hull fixed base 3 near the dock 1. Side support rods 2 are fixedly connected to both sides of the bottom of the gangway 5, and one end of the side support rods 2 extends into the corresponding mounting base 4. Multiple guide limiting protrusions 21 are slidably connected at equal intervals to the middle of the top of the inner side of the mounting base 4. The bottom of the guide limiting protrusions 21 is connected to the corresponding position at the top middle of the side support rod 2.

[0031] When the horizontal buffer mechanism is activated, when the tidal changes and wave impacts cause the ship's hull to experience continuous horizontal swaying, due to the reasonable fit between the limiting ball joint seat 19 on the hull fixed seat 3 and the floating cavity 7 on the ramp 5, the swaying amplitude of the ramp 5 itself will be less than the swaying amplitude of the hull fixed seat 3 on the hull when the ship's hull is swayed by the tides and waves.

[0032] The horizontal buffer mechanism also includes a magnetic base 20 of the same polarity. The inner wall of the mounting base 4 is provided with magnetic bases 20 of the same polarity on both sides. The outer wall of the side support rod 2 is provided with magnetic parts 22 of the same polarity on both sides. The magnetic parts 22 of the same polarity and the magnetic base 20 of the same polarity are the same polarity. There is an adjustable gap between the inner wall of the mounting base 4 and the side support rod 2 that extends into it.

[0033] During the synchronous rocking and swaying process of the hull fixed seat 3 driving the mounting seat 4 on it, the repulsive force between the same magnetic seat 20 inside the mounting seat 4 and the same magnetic part 22 on the side support rod 2 will initially buffer the rocking impact load transmitted from the hull. Furthermore, the frictional resistance formed between the guide limiting protrusion 21 on the side support rod 2 and the mounting seat 4 will further dissipate the rocking energy, so that the rocking force transmitted to the gangplank 5 is buffered and weakened to the greatest extent.

[0034] Please see the appendix Figure 8 The horizontal buffer mechanism also includes a rubber seat 8. Both ends of the slot 9 are fixedly connected to the middle of the rubber seat 8. A cavity 23 is opened on one side of the inside of the rubber seat 8. Multiple micro-hole seats 24 are equidistantly arranged on both sides of the outer wall of the rubber seat 8 near the floating support seat 10. The micro-holes on the micro-hole seats 24 are all connected to the inside of the cavity 23. A side wall rubber layer 11 is provided in the middle of the two side walls of the slot 9.

[0035] When the springboard 5 is subjected to a horizontal swaying force and wobbles, the floating support seat 10 at the bottom of the springboard 5 will continuously squeeze the rubber seat 8 in the slot 9 during the swaying process. When the rubber seat 8 is squeezed by the swaying of the floating support seat 10, the air in its internal cavity 23 will be slowly discharged through the micropores on the microporous seat 24 under pressure. In this process, the compression and discharge of the air in the cavity 23 will initially buffer the swaying force of the springboard 5.

[0036] After the cavity 23 is completely squeezed and closed, the elastic deformation of the rubber seat 8 itself provides secondary buffering of the swing force of the springboard 5. At the same time, the side wall rubber layer 11 in the slot 9 provides flexible elastic buffering of the edge of the bottom floating support seat 10 of the springboard 5, thus completing the multiple buffering treatment of the horizontal swing force of the springboard 5 during use.

[0037] Please see the appendix Figure 9 The board stabilizing mechanism is installed inside the board 5 and is used to stabilize the board 5 when it is facing waves or tides during use. The plate stabilizing mechanism includes a high-viscosity damping liquid cavity 31. The high-viscosity damping liquid cavity 31 is provided in the lower middle part of the inner side of the springboard 5. Multiple universal hinge rods 30 are equidistantly arranged at the top center of the high-viscosity damping liquid cavity 31. The bottom of each universal hinge rod 30 is connected to a universal inertial swing ball 33 that can swing in all directions with a small amplitude. Elastic buffer seats 32 that restrict the universal inertial swing ball 33 are provided on both sides of the inner wall of the high-viscosity damping liquid cavity 31 at positions corresponding to the universal inertial swing ball 33.

[0038] When the board stabilizing mechanism is activated, when the board 5 is subjected to continuous action of waves, resulting in high-frequency small-amplitude swaying, fluttering, or structural resonance, the omnidirectional inertial oscillating ball 33 in the high-viscosity damping liquid cavity 31 remains stationary in relative space due to its own inertia. It forms a stable relative motion with the omnidirectional hinge rod 30 that sways synchronously with the board 5 and the high-viscosity damping liquid cavity 31. During this process, the high-viscosity damping liquid in the high-viscosity damping liquid cavity 31 will generate a continuous and uniform reverse damping torque on the omnidirectional inertial oscillating ball 33, which will quickly absorb and dissipate the swaying energy of the board 5, effectively suppressing high-frequency vibration and structural resonance, and avoiding the continuous superposition and amplification of small-amplitude swaying.

[0039] Meanwhile, the elastic buffer seat 32 inside the high-viscosity damping fluid cavity 31 can effectively limit the swing amplitude of the omnidirectional inertial swing ball 33, preventing it from swinging too much and causing structural impact. This enables automatic leveling of the tilt attitude of the ramp 5 and rapid suppression of small-amplitude swaying, so that the ramp 5 can always remain stable and shake-free under complex sea conditions, thus completing the stable anti-sway treatment of the ramp 5 during use.

[0040] Please see the appendix Figure 10 An automatic balancing mechanism is installed inside the ramp 5 to automatically balance the ramp 5 when it is facing waves or tides during use.

[0041] The automatic balancing mechanism includes a horizontal guide cavity 27. Multiple horizontal guide cavities 27 are equidistantly provided on the upper inner side of the ramp 5. A counterweight slide 26 is slidably connected to the middle of each horizontal guide cavity 27. A reset tension spring 25 is provided at the middle of each end of the horizontal guide cavity 27, and one end of the reset tension spring 25 is connected to the middle of the counterweight slide 26. Rubber damping pads 28 are provided on the upper and lower sides of the inner wall of the horizontal guide cavity 27.

[0042] When the automatic balancing mechanism is activated, if the ramp 5 tilts to the left or right or sways to one side due to the influence of waves and tides during use, the counterweight slide 26 in the horizontal guide cavity 27 does not require external power to drive it. Under its own weight, it automatically slides to the lower side of the ramp 5 along the horizontal guide cavity 27. The counterweight offset generates a reverse restoring torque opposite to the tilting direction, which directly counteracts the tilting torque caused by the external environment. When the tilting load weakens, the return spring 25 will smoothly pull the counterweight slide 26 in the horizontal guide cavity 27 to slowly return to the center, so that the center of gravity of the ramp 5 always approaches its own central axis, maintaining the overall stability of the center of gravity.

[0043] During this process, the rubber damping pads 28 in the horizontal guide cavity 27 can effectively absorb the impact and high-frequency vibration generated during the sliding of the counterweight slide 26, and prevent the movement of the counterweight slide 26 itself from aggravating the shaking of the springboard 5. No external power or manual intervention is required throughout the process, and the springboard 5 is restored to its horizontal balance in real time, passively and automatically, thereby completing the automatic adjustment and balance treatment of the springboard 5 during use.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
