[0002] When a large ship is moored, the crew members on board use the gangway to disembark or transport supplies. Due to the swaying of the ship and the gangway due to the action of the waves and tides, the safety of the crew members cannot be guaranteed. In order to reduce the impact of the gangway shaking on the safety of the crew members, the traditional method is to connect a safety rope to the gangway and the dock for fixing. Since the safety rope is low in cost and easy to operate, it is widely used in small docks. However, the safety rope has high requirements on the personnel's ability and the anti-rolling effect is unstable. When the ship is berthing at a high speed, the gangway swings at a large amplitude and the effect is basically ineffective. In addition, the wind and waves on the dock are relatively large. After long-term use of the existing gangway anti-rolling buffer, water vapor in the wind and waves can easily enter the buffer, causing damage to the buffer, reducing the anti-rolling effect or losing its effect, which is easy to cause accidents for ship personnel getting on and off the gangway.

DETAILED DESCRIPTION
[0021] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a high-sealing gangway anti-roll buffer with adjustable installation distance includes a main body 1, a fixing rod 2 is arranged at one end of the main body 1, and a buffer mechanism 3 capable of moving left and right inside the main body 1 is arranged at the other end of the main body 1. The main body 1 is a barrel-shaped structure, and the buffer mechanism 3 divides the interior of the main body 1 into a two-way chamber 4, and the two-way chamber 4 is filled with a polymer buffer glue. The buffer mechanism 3 includes a movable rod 31 arranged inside the main body 1, and a sealing mechanism 5 is sleeved between the movable rod 31 and the main body 1. Specifically, a high-sealing gangway anti-roll buffer with adjustable installation distance, its structure not only meets the high standard requirements of stability and safety of offshore working platforms or ships, but also takes into account the convenience of maintenance and reliability of long-term use. The main body 1 is made of high-strength corrosion-resistant alloy material, and the barrel-shaped structure design not only optimizes the internal space layout, but also enhances the compression and torsion resistance of the overall structure, ensuring that the structure can maintain stability and integrity under various severe sea conditions. One end of the fixing rod 2 is connected to the main body 1, and the other end is designed with a precise locking device, which is convenient for quick connection with the gangway or other fixed structures, and supports multi-angle adjustment to meet the needs of different installation environments. The locking device has a built-in high-strength spring to ensure that the connection is stable and not easy to loosen. A distance adjustment mechanism is provided between the main body 1 and the fixing rod 2. One end of the fixing rod 2 is provided with an internal thread, and one end of the main body 1 is provided with an external thread. Through the threaded connection between the main body 1 and the fixing rod 2, the fixing rod 2 can be easily fine-tuned by rotating and adjusting the fixing rod 2. The other end of the fixing rod 2 is provided with an external thread, and the external thread is threadedly connected with an adjustment nut, which can adjust the installation distance of the buffer, greatly improving the installation flexibility and adaptability. The buffer mechanism 3 divides the interior of the main body 1 into a two-way chamber 4. The design of the two-way chamber 4 makes full use of the space to make the buffer effect more uniform. The polymer buffer glue filled inside is a special material with high elasticity and high damping, which can effectively absorb and disperse the impact energy of the gangway under the action of waves, significantly reduce the shaking amplitude, and improve the safety of passengers and cargo. At the same time, the material has good weather resistance and aging resistance, and can maintain excellent buffering effect after long-term use. The sealing mechanism 5 between the movable rod 31 and the main body 1 adopts a multiple sealing design, including but not limited to rubber sealing rings, metal sealing rings and oil seals, etc., to ensure that the sealing of the internal chamber can be maintained even under extreme working conditions, and prevent the intrusion of impurities such as seawater and oil pollution, which affect the buffering performance. In addition, the sealing mechanism 5 also has an automatic compensation function, which can automatically adjust the sealing gap with the reciprocating motion of the movable rod 31, further enhancing the sealing effect. In summary, this high-sealing gangway anti-roll buffer with adjustable installation distance, with its innovative structural design, high-quality material selection and efficient buffering mechanism, provides a safer and more stable guarantee for offshore operations.
[0023] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the sealing mechanism 5 includes a fixed block 51 installed at the end of the main body 1, a first sealing groove 52 is arranged on the outside of the fixed block 51, a first sealing ring 53 is sleeved in the first sealing groove 52, a second sealing groove 54 is arranged on the inside of the fixed block 51, and a second sealing ring 55 is sleeved in the second sealing groove 54. Specifically, the fixed block 51, as the basic support member of the sealing mechanism 5, is precisely machined and firmly installed at the end of the main body 1. It is made of high-strength and corrosion-resistant materials that match the main body 1 to ensure that it is not easily deformed or damaged during long-term use. The design of the fixed block 51 also takes into account the needs of easy installation and maintenance, so as to facilitate the inspection or replacement of the seal when necessary. The first sealing groove 52 is opened on the outside of the fixed block 51, and its shape and size are accurately calculated to ensure a close fit with the first sealing ring 53. The first sealing ring 53 is made of high-quality elastic material, such as oil-resistant and water-resistant rubber or silicone material, and has good sealing and aging resistance. When the movable rod 31 moves in the main body 1, the first sealing ring 53 can effectively prevent external impurities such as moisture and dust from entering the internal chamber, keeping the internal environment clean and dry. The second sealing groove 54 is arranged on the inner side of the fixed block 51, corresponding to the first sealing groove 52, but facing the internal space of the main body 1. This design further enhances the sealing effect, especially when a dynamic seal is formed between the movable rod 31 and the main body 1. The second sealing ring 55 is also made of high-quality elastic material, and its shape and hardness may be customized according to specific needs to provide better sealing effect and longer service life. When the movable rod 31 moves left and right inside the main body 1, the first sealing ring 53 and the second sealing ring 55 work together to form two effective sealing barriers. The first sealing ring 53 mainly prevents pollutants from the external environment from entering, while the second sealing ring 55 further ensures the sealing of the two-way chamber 4 to prevent leakage of internal media such as polymer buffer glue. This double sealing design not only improves the reliability of the seal, but also extends the overall service life of the buffer. In addition, in order to cope with the sealing challenges under extreme working conditions, the sealing mechanism 5 may also be equipped with an automatic compensation mechanism or a pressure balancing device to cope with the changes in the sealing gap caused by factors such as temperature changes and pressure fluctuations, so as to ensure that excellent sealing performance can be maintained under any conditions. In summary, the sealing mechanism 5, with its sophisticated structure and efficient sealing mechanism, provides a solid guarantee for the stable operation of the gangway anti-rolling buffer.
[0024] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the main body 1 is provided with an extended edge 11 at the opening, the extended edge 11 is provided with a bolt hole 12, the outer side of the extended edge 11 is provided with a third sealing groove 111, the third sealing ring 112 is provided in the third sealing groove 111, the outer side of the fixed block 51 is provided with a fixed edge 511 matching the extended edge 11, the fixed edge 511 is provided with a hole matching the bolt hole 12, and the fixed edge 511 is fixedly connected with the extended edge 11 by a fixing bolt. Specifically, the structure of the extended edge 11 is carefully designed at the opening of the main body 1, aiming to enhance the sealing and stability between the main body 1 and the external connection parts. On the extended edge 11, the bolt holes 12 are evenly distributed, and the positions and sizes of these holes are accurately calculated to ensure that they can be accurately aligned with the fixed edge 511 on the fixed block 51, and a tight connection is achieved through the fixing bolts. The design of the bolt hole 12 takes into account the convenience during installation and the stability after tightening, which provides convenience for subsequent assembly and maintenance work. In order to further improve the sealing performance, the third sealing groove 111 is specially provided on the outer side of the extended edge 11. The introduction of the third sealing groove 111 forms an additional sealing barrier between the main body 1 and the fixed block 51. The third sealing groove 111 is embedded with a third sealing ring 112, which is made of high-quality elastic material, has good compression resilience and corrosion resistance, and can fit tightly to the groove wall and corresponding sealing surface of the third sealing groove 111 when squeezed, effectively preventing the penetration of liquid, gas or tiny particles. The outside of the fixed block 51 is carefully designed with a fixed edge 511 that matches the extended edge 11. This design not only ensures that the fixed block 51 can be accurately aligned during installation, but also achieves a stable connection between the two by matching the holes on the fixed edge 511 with the bolt holes 12 on the extended edge 11. The design of the holes also takes into account the requirements of installation accuracy and tightening strength to ensure that there will be no misalignment or loosening during the tightening process. In the actual installation process, first align the fixed edge 511 of the fixed block 51 with the extended edge 11 of the main body 1 to ensure that the third sealing ring 112 is correctly placed in the third sealing groove 111. Subsequently, the fixing bolts are passed through the bolt holes 12 and the holes in sequence, and appropriate tightening torque is applied to firmly fix the fixing block 51 on the main body 1. In this process, the third sealing ring 112 is squeezed and deformed, and fits tightly between the third sealing groove 111 and the sealing surface, forming a reliable sealing effect.
[0025] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a movable block 32 is provided at the top of the movable rod 31, a fourth sealing groove 33 is provided on the movable block 32, and a sealing gasket 34 is sleeved in the fourth sealing groove 33. Specifically, a movable block 32 is provided at the top of the movable rod 31, and a fourth sealing groove 33 is provided on the movable block 32, and the shape and size of the fourth sealing groove 33 perfectly match the sealing gasket 34. As a core component for realizing the sealing function, the material selection of the sealing gasket 34 is very important. The sealing gasket 34 is made of high-quality elastic materials, such as rubber or silicone materials that are oil-resistant, water-resistant, and high-temperature resistant. These materials have good compression resilience, wear resistance, and corrosion resistance, and can maintain stable sealing performance under harsh working environments. The shape of the sealing gasket 34 matches the fourth sealing groove 33, and can be easily inserted into the groove during installation, and fits tightly to the groove wall and the corresponding sealing surface when squeezed, forming a reliable sealing barrier. When the movable rod 31 reciprocates inside the main body 1, the sealing gasket 34 on the movable block 32 will play an important role. It can effectively prevent external impurities such as moisture and dust from entering the interior of the main body, and prevent internal media such as lubricating oil and buffer rubber from leaking to the outside. This dual protection mechanism ensures the cleanliness and dryness of the internal environment of the anti-roll buffer, and extends the service life of the equipment. In addition, the sealing gasket 34 also has a certain buffering effect, which can reduce the impact and vibration generated by the movable rod 31 during movement to a certain extent, thereby improving the stability and reliability of the equipment. At the same time, since the sealing gasket 34 is made of elastic material, it also has a certain adaptive ability, and can adapt to changes in the sealing gap caused by factors such as temperature changes and pressure fluctuations, ensuring that excellent sealing performance can be maintained under any working conditions.
[0026] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the main body 1 is covered with a cushion pad 6, and the cushion pad 6 is provided with anti-skid patterns. Specifically, the main body 1 is the core structure of the anti-roll buffer, and its outer side is covered with a layer of cushion pad 6. This design not only enhances the protection performance of the main body 1, but also improves the safety and comfort of the user during use. In order to further improve the safety during use, the surface of the cushion pad 6 is provided with anti-skid patterns. These patterns have excellent anti-skid performance, which can ensure that users can avoid accidents caused by sliding or falling off in slippery or inclined working environments.
[0027] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first sealing ring 53, the second sealing ring 55, the third sealing ring 112 and the sealing pad 34 are all made of rubber material. Specifically, the first sealing ring 53, the second sealing ring 55, the third sealing ring 112 and the sealing pad 34, as the critical sealing components in the anti-roll buffer, are all made of high-quality rubber material. Rubber material is well known for its excellent elasticity and sealing performance. It can fit tightly on the sealing groove or sealing surface when under pressure to form a reliable sealing barrier. In addition, the rubber material also has good wear resistance and corrosion resistance, and can maintain stable performance in harsh working environments. For anti-roll buffers, their working environment is often accompanied by vibration, impact and possible chemical contact, so the durability and corrosion resistance of the sealing components are particularly important. Sealing rings and sealing pads made of rubber material can effectively resist the influence of these adverse factors and extend the service life of the equipment.
[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 1, the fixed rod 2 and the movable rod 31 are all made of metal. Specifically, the main body 1, the fixed rod 2 and the movable rod 31, as the core structural components of the anti-roll buffer, are all made of metal. Metal materials are known for their excellent mechanical properties and can withstand greater pressure and load, ensuring that the anti-roll buffer can remain stable when subjected to impact or vibration. As the supporting structure of the entire device, the main body 1 needs to withstand the reciprocating motion from the movable rod 31 and possible external impacts. Therefore, the use of metal materials can ensure that it is sturdy and durable and not easy to deform or damage. The fixed rod 2 plays the role of connecting and supporting the movable rod 31. The fixed rod 2 made of metal not only has sufficient strength to support the weight and movement force of the movable rod 31, but also can maintain high-precision straightness and parallelism, ensuring that the movable rod 31 can move smoothly. As a key active component in the anti-roll buffer, the movable rod 31 made of metal not only has sufficient rigidity and strength to withstand the impact and vibration of reciprocating motion, but also can maintain stable performance in harsh working environments.
[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a gangway ladder comprises a gangway ladder mounting frame, on which are mounted a plurality of high-sealed gangway ladder anti-roll buffers with adjustable mounting distances as described above.
