Description

Technical Field

[0001] This utility model belongs to the technical field of ecological wharf auxiliary devices, specifically an ecological wharf boarding device suitable for water level fluctuations. Background Technology

[0002] Wharves are vital transportation nodes connecting land and water, undertaking core functions such as cargo loading and unloading, passenger transport, and ship resupply. Wharves are fixed facilities built in waterways, typically consisting of ecological structures such as embankments, piers, and breakwaters, and equipped with cranes and warehouses. Their core functions include: cargo distribution: approximately 90% of global international trade goods are transported through wharves; passenger transfer: for example, Nanjing Zhongshan Wharf, a century-old ferry hub, remains an important commuting route for residents on both sides of the Yangtze River; and ship services: providing fuel replenishment, maintenance, and ensuring navigational safety.

[0003] In existing technologies, the boarding structures or methods used for ecological wharves with large water level fluctuations are often cumbersome, time-consuming, and require significant manpower, resulting in high overall costs. Furthermore, the anti-slip properties of the passageways are poor, and there is a lack of structures that allow for stable gripping, making it easy for people to fall due to insufficient friction or unstable grip, thus requiring improved safety. Therefore, a boarding device suitable for ecological wharves with fluctuating water levels is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an ecological dock boarding device suitable for water level fluctuations, which solves the technical problem that the aforementioned passageway has poor anti-slip performance and lacks a structure that facilitates stable gripping by personnel, making it easy for people to fall due to insufficient friction or unstable gripping when passing through, and thus requiring improved safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological dock boarding device suitable for water level fluctuations, comprising:

[0006] The sloping wharf, and the diamond-shaped anti-slip steel mesh installed on the upper surface of the sloping wharf, and the upper surface of the sloping wharf is equipped with a boarding ladder extension section, and a boarding ladder base plate is connected between the boarding ladder extension section and the sloping wharf.

[0007] The boarding ladder handrail is installed on the upper surface of the boarding ladder telescopic section, and the boarding ladder counterweight is also installed on the upper surface of the boarding ladder telescopic section.

[0008] The boarding ladder telescopic section includes longitudinal telescopic rods, which are set on both sides of the upper surface of the sloping wharf, and transverse support rods are installed between adjacent longitudinal telescopic rods. The telescopic ends of the longitudinal telescopic rods are all equipped with boarding ladder hooks.

[0009] When in use, the sloping wharf is first set up in the corresponding area of ​​the wharf, and the diamond-shaped anti-slip steel mesh on its surface provides an anti-slip base for people to go up and down;

[0010] When the water level fluctuates, the length of the boarding ladder extension section is adaptively adjusted according to the water level by adjusting the longitudinal telescopic rods included in the extension section; the transverse support rods between adjacent longitudinal telescopic rods maintain the structural stability of the boarding ladder extension section during the adjustment process.

[0011] After adjustment, connect the boarding ladder hook at the telescopic end of the longitudinal telescopic rod to the moored vessel to achieve a stable connection between the boarding ladder telescopic section and the vessel; the boarding ladder base plate is always connected to the boarding ladder telescopic section and the sloping dock to ensure a reliable connection between the two.

[0012] When boarding or disembarking, passengers can hold onto the handrails of the boarding ladder to ensure safe movement. The counterweight of the boarding ladder maintains the overall balance of the telescopic section of the boarding ladder through its own weight, preventing tilting due to uneven force.

[0013] Preferably, a drive motor is mounted on the upper surface of the longitudinal telescopic rod, and a motor mount is installed between the drive motor and the longitudinal telescopic rod. The motor mount enhances the stability of the connection between the drive motor and the longitudinal telescopic rod, preventing the drive motor from loosening or shifting due to vibration or other factors during operation, providing a stable mounting foundation for the drive motor, and ensuring the stability of its subsequent power output.

[0014] Preferably, each of the longitudinal telescopic rods has a positioning groove on its front side, and a positioning plate is slidably connected to the inner cavity of each positioning groove. The positioning groove provides a clear sliding path for the positioning plate, which can limit the direction of movement of the positioning plate, prevent lateral deviation or shaking during the sliding process, ensure the stability of the positioning plate during the sliding process, and lay the foundation for subsequent cooperation with other structures.

[0015] Preferably, both the positioning groove and the positioning plate are "I"-shaped, and their positions and shapes correspond. The positioning plate is connected to the corresponding boarding ladder hook. The "I"-shaped design increases the contact area between the positioning groove and the positioning plate, improves the tightness of their fit, effectively prevents the positioning plate from detaching from the positioning groove, and enhances the reliability of the structural connection. At the same time, the connection between the positioning plate and the boarding ladder hook allows the boarding ladder hook to move synchronously through the sliding of the positioning plate, ensuring the stability of the boarding ladder hook's movement.

[0016] Preferably, toothed blocks are evenly installed on both sides of the positioning plate, and gears mesh with the positioning plate through the toothed blocks. The meshing transmission method of the toothed blocks and gears has high transmission efficiency, which can ensure the stability and accuracy of power transmission, and enable precise control of the moving speed and displacement of the positioning plate, avoiding transmission failure problems such as slippage.

[0017] Preferably, the gear is rotatably connected to both sides of the inner cavity of the longitudinal telescopic rod, and a rotating shaft is installed at the center of the gear. The rotatable connection between the gear and the longitudinal telescopic rod ensures that the gear can rotate smoothly and reduces frictional resistance during rotation; the installation of the rotating shaft provides a stable center of rotation for the gear, and facilitates the transmission of external power to the gear, ensuring the stability of gear rotation and the continuity of power transmission.

[0018] Preferably, the top end of the rotating shaft extends outward through the inner wall of the longitudinal telescopic rod, and the rotating shaft is coaxially connected to the corresponding drive motor. The rotating shaft's penetration through the inner wall of the longitudinal telescopic rod facilitates connection to the drive motor, while the coaxial connection minimizes power transmission losses, ensuring that the drive motor's power is efficiently and directly transmitted to the gears via the rotating shaft, achieving synchronous power transmission and making the positioning plate's movement response more timely.

[0019] Preferably, the longitudinal telescopic rod is a double-layer nested square steel tube, and positioning holes are evenly distributed on the upper surface of the longitudinal telescopic rod and the positioning plate, with pins inserted into the inner cavity of the positioning holes. The double-layer nested square steel tube structure can significantly improve the overall structural strength and telescopic stability of the longitudinal telescopic rod, making it less prone to deformation during load bearing and telescopic processes; the cooperation between the positioning holes and the pins can quickly fix the position of the longitudinal telescopic rod and the positioning plate under specific working conditions, preventing relative movement between the two due to accidental force, and improving the safety and reliability of the structure during use.

[0020] Compared with the prior art, this utility model provides an ecological dock boarding device suitable for water level fluctuations, which has the following beneficial effects:

[0021] This ecological dock boarding device, suitable for water level fluctuations, allows for the extension of the boarding ladder to the required length after the vessel docks. Counterweights are added according to the extension length, and the boarding ladder hooks are then fastened into the bow bollard or bulwark. This reduces deployment time and saves overall costs.

[0022] The diamond-shaped anti-slip steel mesh helps to increase friction when people pass through, ensuring safety. The handrails of the boarding ladder are easy for people to hold, enhancing safety during passage. This dual measure reduces the risk of falls. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a technical solution for a boarding device at an ecological wharf with fluctuating water levels, including: (See details) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The sloping pier 6, and the diamond-shaped anti-slip steel mesh 32 set on the upper surface of the sloping pier 6, and the upper surface of the sloping pier 6 is provided with a boarding ladder extension section 3, and a boarding ladder base plate 4 is connected between the boarding ladder extension section 3 and the sloping pier 6.

[0032] The boarding ladder handrail 1 is installed on the upper surface of the boarding ladder telescopic section 3, and the boarding ladder counterweight 5 is also installed on the upper surface of the boarding ladder telescopic section 3.

[0033] The boarding ladder extension section 3 includes a longitudinal extension rod 31, which is set on both sides of the upper surface of the sloping wharf 6. A transverse support rod 33 is installed between adjacent longitudinal extension rods 31, and a boarding ladder hook 2 is installed at the extension end of each longitudinal extension rod 31.

[0034] When in use, the sloping wharf 6 is first set up in the corresponding area of ​​the wharf, and the diamond-shaped anti-slip steel mesh 32 on its surface provides an anti-slip base for people to go up and down;

[0035] When the water level fluctuates, the length of the boarding ladder extension section 3 is adaptively adjusted according to the water level by adjusting the longitudinal telescopic rods 31 included in the boarding ladder extension section 3; the transverse support rods 33 between adjacent longitudinal telescopic rods 31 maintain the structural stability of the boarding ladder extension section 3 during the adjustment process.

[0036] After adjustment, the boarding ladder hook 2 at the telescopic end of the longitudinal telescopic rod 31 is connected to the docked vessel to achieve a stable connection between the boarding ladder telescopic section 3 and the vessel; the boarding ladder base plate 4 is always connected to the boarding ladder telescopic section 3 and the sloping dock 6 to ensure a reliable connection between the two.

[0037] When boarding or disembarking, people can hold onto the boarding ladder handrail 1 to ensure safe movement. The boarding ladder counterweight 5 maintains the overall balance of the boarding ladder telescopic section 3 through its own weight, preventing tilting due to uneven force.

[0038] The length of the longitudinal telescopic rod 31 of the boarding ladder telescopic section 3 can be flexibly adjusted to adapt to different water level fluctuations, ensuring effective docking with the vessel even when the water level rises or falls, thus improving the applicability of the device.

[0039] The diamond-shaped anti-slip steel mesh 32 installed on the surface of the sloping dock 6 can enhance the friction when people walk on it. Together with the boarding ladder handrail 1, it provides double safety protection for people boarding the ship and reduces the risk of slipping or falling.

[0040] Please see Figure 4 A drive motor 7 is mounted on the upper surface of the longitudinal telescopic rod 31, and a motor mount is installed between the drive motor 7 and the longitudinal telescopic rod 31. The drive motor 7 is installed on the upper surface of the longitudinal telescopic rod 31. During installation, the motor mount is assembled between the drive motor 7 and the longitudinal telescopic rod 31, and the drive motor 7 is securely connected to the longitudinal telescopic rod 31 through the motor mount. The motor mount enhances the stability of the connection between the drive motor 7 and the longitudinal telescopic rod 31, preventing the drive motor 7 from loosening or shifting due to vibration or other factors during operation, providing a stable mounting foundation for the drive motor 7, and ensuring the stability of its subsequent power output.

[0041] Please see Figure 5Each longitudinal telescopic rod 31 has a positioning groove 8 on its front side, and a positioning plate 9 is slidably connected to the inner cavity of each positioning groove 8. The positioning groove 8 is opened on the front side of the longitudinal telescopic rod 31, and then the positioning plate 9 is placed into the inner cavity of the corresponding positioning groove 8, allowing the positioning plate 9 to slide along the extension direction of the positioning groove 8. The positioning groove 8 provides a clear sliding path for the positioning plate 9, restricting its direction of movement and preventing lateral deviation or wobbling during sliding, ensuring the stability of the positioning plate 9's sliding process and laying the foundation for subsequent cooperation with other structures. Both the positioning groove 8 and the positioning plate 9 are "I"-shaped, and their positions and shapes correspond. The positioning plate 9 is connected to the corresponding boarding ladder hook 2. Both the positioning groove 8 and the positioning plate 9 are designed in an "I" shape to ensure that their positions and shapes match each other. Then, the positioning plate 9 is connected and fixed to the corresponding boarding ladder hook 2. The "I" shape design can increase the contact area between the positioning groove 8 and the positioning plate 9, improve the tightness of their fit, effectively prevent the positioning plate 9 from detaching from the positioning groove 8, and enhance the reliability of the structural connection. At the same time, the connection between the positioning plate 9 and the boarding ladder hook 2 can drive the boarding ladder hook 2 to move synchronously through the sliding of the positioning plate 9, ensuring the stability of the movement of the boarding ladder hook 2.

[0042] Please see Figure 6The positioning plate 9 has evenly spaced toothed blocks 10 on both sides, and the positioning plate 9 meshes with gears 11 through the toothed blocks 10. The evenly spaced toothed blocks 10 on both sides of the positioning plate 9 allow the positioning plate 9 to mesh with the gears 11 through the toothed blocks 10 on both sides. This meshing transmission method between the toothed blocks 10 and the gears 11 has high transmission efficiency, ensuring the stability and accuracy of power transmission, and allowing precise control of the moving speed and displacement of the positioning plate 9, avoiding transmission failures such as slippage. The gears 11 are rotatably connected to both sides of the inner cavity of the longitudinal telescopic rod 31, and a rotating shaft 12 is installed at the center of the gears 11. Gear 11 is rotatably connected to both sides of the inner cavity of the longitudinal telescopic rod 31, allowing gear 11 to rotate flexibly around the connection point. A rotating shaft 12 is then installed at the center of gear 11, ensuring that the shaft 12 rotates synchronously with gear 11. The rotatable connection between gear 11 and the longitudinal telescopic rod 31 ensures smooth rotation of gear 11 and reduces frictional resistance during rotation. The installation of the rotating shaft 12 provides a stable center of rotation for gear 11 and facilitates the transmission of external power to gear 11, ensuring the stability of gear 11's rotation and the continuity of power transmission. The top end of the rotating shaft 12 extends outward through the inner wall of the longitudinal telescopic rod 31, and the rotating shaft 12 is coaxially connected to the corresponding drive motor 7. The top end of the rotating shaft 12 passes through the inner wall of the longitudinal telescopic rod 31 and extends outward. After extension, the rotating shaft 12 is coaxially connected to the corresponding drive motor 7, ensuring that their rotation axes coincide. The rotating shaft 12 passes through the inner wall of the longitudinal telescopic rod 31 for easy connection with the drive motor 7. The coaxial connection method can minimize the loss in the power transmission process, ensuring that the power of the drive motor 7 can be efficiently and directly transmitted to the gear 11 through the rotating shaft 12, achieving synchronous power transmission and making the movement response of the positioning plate 9 more timely. The longitudinal telescopic rod 31 is a double-layer nested square steel tube, and positioning holes are evenly opened on the upper surface of the longitudinal telescopic rod 31 and the positioning plate 9. Pins are inserted into the inner cavity of the positioning holes. The longitudinal telescopic rod 31 adopts a double-layer nested square steel tube structure. Positioning holes are uniformly machined on the upper surfaces of the longitudinal telescopic rod 31 and the positioning plate 9. When it is necessary to fix the relative position of the longitudinal telescopic rod 31 and the positioning plate 9, the pin is inserted into the corresponding positioning hole cavity. The double-layer nested square steel tube structure can significantly improve the overall structural strength and telescopic stability of the longitudinal telescopic rod 31, making it less prone to deformation during load bearing and telescopic processes. The cooperation between the positioning holes and the pins can quickly fix the position of the longitudinal telescopic rod 31 and the positioning plate 9 under specific working conditions, preventing relative movement between the two due to accidental force, and improving the safety and reliability of the structure during use.

[0043] In this embodiment: when the water level fluctuates, the length of the boarding ladder extension section 3 is adaptively adjusted with the water level by adjusting the longitudinal telescopic rods 31 included in the boarding ladder extension section 3. The transverse support rods 33 between adjacent longitudinal telescopic rods 31 maintain the structural stability of the boarding ladder extension section 3 during the adjustment process.

[0044] After adjustment, the boarding ladder hook 2 at the telescopic end of the longitudinal telescopic rod 31 is connected to the docked vessel to achieve a stable connection between the boarding ladder telescopic section 3 and the vessel. The boarding ladder base plate 4 is always connected to the boarding ladder telescopic section 3 and the sloping dock 6 to ensure a reliable connection between the two.

[0045] When boarding or disembarking, people can hold onto the boarding ladder handrail 1 to ensure safe movement. The boarding ladder counterweight 5 maintains the overall balance of the boarding ladder telescopic section 3 through its own weight, preventing tilting due to uneven force.

[0046] The longitudinal telescopic rod 31 of the boarding ladder telescopic section 3 can be flexibly adjusted in length to adapt to different water level fluctuations, ensuring effective docking with the vessel even when the water level rises or falls, thus improving the applicability of the device. The diamond-shaped anti-slip steel mesh 32 set on the surface of the sloping dock 6 can enhance the friction when people walk on it. Together with the boarding ladder handrail 1, it provides double safety protection for boarding personnel and reduces the risk of slipping or falling.
