DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0034] like Figure 1 , Figure 2 As shown, Figure 1 A schematic top view of a gate boarding system provided in an embodiment of the present application, Figure 2A front view of a gate system provided in an embodiment of the present application, a gate boarding system, which is intended to improve boarding efficiency and safety, the gate boarding system includes a ship ladder system and a gate system, wherein:

[0035] like Figure 1 , Figure 3 As shown, Figure 3 A side view of a ship ladder main body 100 provided in an embodiment of the present application, wherein the ship ladder system comprises a ship ladder main body 100, a first connecting member 200 and a second connecting member 300, wherein the first connecting member 200 is used to be fixedly arranged on a pontoon 501, and the second connecting member 300 is used to be connected to a hull 502, and both ends of the ship ladder main body 100 are movably connected to the first connecting member 200 and the second connecting member 300, respectively, and a widening section 101 is provided in the middle of the ship ladder main body 100;

[0036] The ship ladder main body 100 is the basic part of the ship ladder system. The ship ladder main body 100 can be made of strong and durable materials to ensure stable use in various environments. The ship ladder main body 100 needs to have sufficient strength and rigidity to bear the weight of personnel and equipment. The surface of the ship ladder main body 100 may adopt anti-skid materials to increase safety.

[0037] like Figure 1 , Figure 2 As shown, a widened section 101 is provided in the middle of the main body 100 of the ship ladder. The widened section 101 can be used as a platform for the passage and transfer of personnel, equipment, etc., thereby improving the convenience of boarding the ship.

[0038] The first connecting member 200 is fixed on the pontoon 501 to ensure a firm connection with the pontoon 501, while allowing a movable connection of the ladder body 100 to ensure the stability of the ladder in severe weather or sea conditions. The movable connection of the first connecting member 200 allows for easy operation so that the ladder body 100 can be quickly deployed or recovered when needed.

[0039] The second connector 300 is used to connect the ship ladder main body 100 to the hull 502. The second connector 300 needs to have sufficient strength and flexibility to adapt to the relative movement of the hull 502. The configuration of the second connector 300 also takes into account the compatibility with the hull 502 to ensure quick and safe connection and disconnection.

[0040] like Figure 1 , Figure 2As shown, the gate system includes a first gate assembly 401 and a second gate assembly 402, and the first gate assembly 401 and the second gate assembly 402 are sequentially arranged in the widening section 101 along the width direction of the ship ladder main body 100, the first gate assembly 401 has a first state of normal closing and a second state of opening after verification, the second gate assembly 402 has a third state of normal closing and a fourth state of active opening, and the passing width of the second gate assembly 402 is greater than the passing width of the first gate assembly 401.

[0041] The first gate assembly 401 is a gate system arranged on one side of the widened section 101 of the ship ladder main body 100. The first gate assembly 401 has two states: a first state that is normally closed and a second state that is opened after verification.

[0042] like Figure 1 , Figure 6 As shown, Figure 6 A schematic diagram of passage on the gate boarding system provided in an embodiment of the present application shows that in the normally closed first state, the first gate assembly 401 is used to prevent all unauthorized passage, ensuring that only verified personnel or equipment can pass through the widened section 101 and enter the next area. When the personnel or equipment passes the verification, the first gate assembly 401 switches to the second state to allow passage.

[0043] In actual configuration, the first gate assembly 401 may be equipped with a variety of verification technologies, such as an RFID reader, a biometric recognition system, and the like.

[0044] The second gate assembly 402 is the second channel of the gate system established in the widening section 101, which is arranged opposite to the first gate assembly 401 and also located in the widening section 101 of the ship ladder main body 100. The second gate assembly 402 has a third state of normally closed and a fourth state of active opening.

[0045] In the third state of the second gate assembly 402 being normally closed, the second gate assembly 402 remains closed to prevent unauthorized passage. The fourth state of the second gate assembly 402 is actively open, which means that under certain conditions (such as emergency situations or system instructions), the second gate assembly 402 can be automatically opened to allow quick passage.

[0046] The passage width of the second gate assembly 402 is designed to be larger than the passage width of the first gate assembly 401, which may be to accommodate larger equipment or to quickly evacuate personnel in an emergency.

[0047] When people or equipment arrive at the first gate assembly 401, they need to be authenticated. After successful authentication, the first gate assembly 401 opens and allows passage. In an emergency, the second gate assembly 402 can be set to open automatically to quickly evacuate people or allow the entry of emergency rescue equipment.

[0048] The second gate assembly 402 provides flexibility in dealing with emergencies, ensuring rapid response when needed, and can adapt to different boarding requirements while ensuring the safety of personnel and equipment.

[0049] The gate boarding system requires safety measures, including but not limited to emergency escape routes, automatic alarm systems, etc. This gate boarding system not only improves the efficiency of boarding, but also greatly enhances the safety and reliability of the boarding process. Through precise control and intelligent management, it can effectively cope with the challenges of various offshore operations.

[0050] In an optional embodiment, the working principle of the gate boarding system in the present application is: the gate boarding system includes a ship ladder system and a gate system, the ship ladder system includes a ship ladder main body 100, a first connecting member 200 and a second connecting member 300, the first connecting member 200 is used to be fixed on the pontoon 501, the second connecting member 300 is used to be connected to the hull 502, the two ends of the ship ladder main body 100 can be movably connected to the first connecting member 200 and the second connecting member 300 respectively, the ship ladder main body The middle part of the ladder body 100 is provided with a widening section 101, and the gate system includes a first gate assembly 401 and a second gate assembly 402. The first gate assembly 401 and the second gate assembly 402 are sequentially arranged in the widening section 101 along the width direction of the ship ladder body 100. The first gate assembly 401 has a first state of normal closing and a second state of opening after verification. The second gate assembly 402 has a third state of normal closing and a fourth state of active opening. The passing width of the second gate assembly 402 is The width of the ladder body 100 is greater than the passing width of the first gate assembly 401. In the actual operation process, the ladder body 100 is built between the pontoon 501 and the hull 502. When the pontoon 501 and the hull 502 are relatively displaced, the ladder body 100 maintains a stable relative state through the first connecting member 200 and the second connecting member 300, which is convenient for the operation personnel to pass through and has strong reliability. The widened section 101 in the middle of the ladder body 100 provides a stable and redundant arrangement space for the first gate assembly 401 and the second gate assembly 402, avoiding the pontoon The space on the ship 501 is squeezed. By switching between different operating states of the first gate assembly 401, the operators can manage and control the upper and lower hull 502 in sequence. By switching between different operating states of the second gate assembly 402, a channel with a larger passing width is provided, which provides smooth passage conditions for people carrying tools, work clothes or equipment, further improving the passage efficiency and applicability. In the face of emergency, the first gate assembly 401 and the second gate assembly 402 can also provide a passage to leave the boat at the same time, thereby improving the dredging capacity and safety.

[0051] like Figure 1 , Figure 3 As shown, in an optional embodiment, the gate system includes a connected identification system and a control system, the identification system is used to collect video image data and transmit the video image data to the control system, the control system is respectively connected to the first gate component 401 and the second gate component 402, the control system can process the video image data, and control the first gate component 401 to switch between the first state and the second state, and / or the second gate component 402 to switch between the third state and the fourth state.

[0052] The gate systems are interconnected through identification systems and control systems and work together.

[0053] The main function of the recognition system is to collect video image data. This usually involves a camera or other image capture device installed at the entrance of the gate, which can capture images of people or objects passing through the gate in real time. This image data is then transmitted to the control system to provide basic information for subsequent processing and decision-making.

[0054] The control system receives and processes the video image data from the identification system. The control system usually contains high-performance processors and advanced algorithms that can analyze the video image data to identify the identity, behavior patterns or other key information of the personnel. Based on this information, the control system can make corresponding decisions to control the status of the gate components.

[0055] like Figure 1 , Figure 6 As shown, in this embodiment, the control system connects the first gate assembly 401 and the second gate assembly 402. The first gate assembly 401 can switch between a first state and a second state, corresponding to the channel at the first gate assembly 401 being in an open and closed state, or other different working modes of the first gate assembly 401 related to access rights. For example, the first state may be that the gate is open and access is allowed; the second state may be that the gate is closed and access is prohibited. The control system automatically controls the first gate assembly 401 to switch between the two states based on the data provided by the identification system to ensure that only authorized persons or objects can pass.

[0056] like Figure 6 As shown, similarly, the second gate assembly 402 can also switch between the third state and the fourth state. It should be noted that the different states of the second gate assembly 402 can correspond to the different states of the first gate assembly 401, or completely different working modes, depending on the design and application scenario of the boarding system. The control system ensures that the second gate assembly 402 can switch to the correct state at the appropriate time through precise logical judgment and control instructions to maintain the safety and efficiency of the gate system. Real-time acquisition, processing and response of video image data are realized to improve safety and traffic efficiency.

[0057] like Figure 1 , Figure 4 As shown, Figure 4 A partial cross-sectional view of the first connecting member 200 provided in an embodiment of the present application, in an optional embodiment, a U-shaped groove 201 for accommodating one end of the ship ladder main body 100 is provided on the first connecting member 200, so that the end of the ship ladder main body 100 can slide in the U-shaped groove 201.

[0058] The U-shaped groove 201 provided on the first connecting member 200 is used to accommodate one end of the ship ladder main body 100, allowing one end of the ship ladder main body 100 to slide freely in the groove, thereby providing a flexible connection method, so that the ship ladder main body 100 can be adjusted and positioned as needed, and the relative displacement between the ship ladder main body 100 and the first connecting member 200 can offset the relative displacement between the ship ladder main body 100 and the pontoon 501 caused by load changes or water surface fluctuations, providing a flexible and reliable connection method to adapt to different usage conditions and environments.

[0059] like Figure 1 , Figure 4 As shown, in an optional embodiment, the first connecting member 200 includes two ears 202 fixed at intervals on the pontoon 501, and a connecting rod 203 fixedly connected between the two ears 202, and the ears 202 and the connecting rod 203 enclose the U-shaped groove 201.

[0060] The first connecting member 200 is fixed to the pontoon 501 at intervals through two ears 202, and the two ears 202 are the main connection points between the first connecting member 200 and the pontoon 501. The ears 202 need to ensure sufficient strength and stability so as to be able to bear the weight of the ship ladder main body 100 and the transmission of various forces that may occur during use. The connecting rod 203 is a component fixedly connected between the two ears 202, and the connecting rod 203 and the ears 202 together enclose a U-shaped groove 201. The size and shape of this U-shaped groove 201 are configured corresponding to one end of the ship ladder main body 100 to ensure that the end of the ship ladder main body 100 can be relatively stably placed in the U-shaped groove 201 and slide smoothly in the groove. It should be noted that the spacing between the two ears 202 can be greater than the width of the end of the ship ladder main body 100 to provide a certain sliding space for the ship ladder main body 100 to adaptively displace in the width direction.

[0061] The end of the ship ladder main body 100 is provided with a shape matching the U-shaped groove 201, so that the end of the ship ladder main body 100 can be easily placed in the U-shaped groove 201. The sliding mechanism between the ship ladder main body 100 and the first connecting member 200 allows the crew to adjust the position of the ship ladder main body 100 when necessary, such as when the tide changes or the berthing position of the ship changes. The connection relationship between the ship ladder main body 100 and the first connecting member 200 also provides a safety mechanism, which can maintain the stability and safety of the ship ladder even when the ship ladder main body 100 is subjected to an unexpected impact or load change. It can not only adapt to different environments and operating conditions, but also improve the efficiency and safety of the use of the ship ladder main body 100.

[0062] like Figure 1 , Figure 5 As shown, Figure 5A partial cross-sectional view of the second connecting member 300 provided in an embodiment of the present application, in an optional embodiment, the second connecting member 300 includes a first restraint portion 301 fixedly provided on the hull 502, and a second restraint portion 302 fixedly connected to the ship ladder main body 100, and the second restraint portion 302 is movably concentrically connected to the first restraint portion 301 so that the ship ladder main body 100 can rotate relative to the hull 502.

[0063] The second connecting member 300 provides a flexible connection between the ship ladder main body 100 and the hull 502, allowing the ship ladder main body 100 to rotate relative to the hull 502 within a preset range, thereby adapting to different usage requirements and environmental conditions. The second connecting member 300 includes a first restraining portion 301 and a second restraining portion 302.

[0064] The first constraint part 301 is fixedly arranged on the hull 502. The first constraint part 301 serves as a fixed connection point between the ship ladder main body 100 and the hull 502, providing the necessary stability and support. The specific setting of the first constraint part 301 must ensure sufficient strength and durability so that it can maintain its function in various marine environments. The second constraint part 302 is fixedly connected to the ship ladder main body 100, and the second constraint part 302 can be movably connected concentrically to the first constraint part 301. Through the concentric connection between the second constraint part 302 and the first constraint part 301, the ship ladder main body 100 is allowed to rotate relative to the hull 502 within a certain range. Such flexibility is essential for adapting to the movement of the hull and the influence of waves.

[0065] like Figure 1 , Figure 5 As shown, in an optional embodiment, the second constraint portion 302 includes two bases 303 fixedly connected to the ship ladder main body 100 at intervals, and a positioning rod 304 detachably fixed between the two bases 303, and a through space is provided at the center of the first constraint portion 301, and the positioning rod 304 can be inserted into the through space.

[0066] Specifically, the second restraining part 302 includes two bases 303 fixedly connected to the ship ladder main body 100 at intervals, and a positioning rod 304 detachably fixed between the two bases 303. The positioning rod 304 can be easily installed or removed when necessary, which is convenient for maintenance and adjustment of the ship ladder main body 100. The base 303 ensures sufficient bearing capacity and stability to support the weight of the positioning rod 304 and the ship ladder main body 100.

[0067] A through space is provided at the center of the first constraint portion 301, and the through space allows the positioning rod 304 to pass through it. This not only provides a simple and effective connection method, but also allows the ship ladder main body 100 to perform limited rotation under the guidance of the positioning rod 304. The size and shape of the through space are set corresponding to the specifications of the positioning rod 304 to ensure that the positioning rod 304 can pass through smoothly, and at the same time provide sufficient friction during rotation to prevent the ship ladder from accidentally sliding or over-rotating.

[0068] The second connecting member 300 in this optional embodiment provides a flexible and stable connection solution, allowing the main member 100 of the ship ladder to rotate as needed while maintaining connection with the hull 502, so as to adapt to different usage scenarios and environmental changes. This not only improves the practicality and safety of the ship ladder, but also simplifies the installation and maintenance process of the ship ladder.

[0069] like Figure 1 , Figure 3 As shown, in an optional embodiment, the ship ladder main body 100 includes a first reinforcement member 102 extending along the length direction and a second reinforcement member 103 extending along the width direction.

[0070] The ship ladder main body 100 enhances the structural stability and load-bearing capacity through the first reinforcement member 102 and the second reinforcement member 103, thereby ensuring the durability and safety of the ship ladder main body 100 under various use conditions.

[0071] The ship ladder main body 100 includes a first reinforcement member 102 extending in the length direction and a second reinforcement member 103 extending in the width direction. The crisscross reinforcement member layout of the first reinforcement member 102 and the second reinforcement member 103 provides a solid channel foundation for the ship ladder main body 100, so that the ship ladder main body 100 can withstand greater loads and pressures while maintaining structural integrity.

[0072] In order to further improve the stability, the first reinforcement member 102 extending along the length direction and the second reinforcement member 103 extending along the width direction are fixedly connected at the intersection, and specifically, they can be fastened by welding or fixing connectors.

[0073] like Figure 1 , Figure 3 As shown, in an optional embodiment, the first reinforcement member 102 and the second reinforcement member 103 respectively include a plurality of U-shaped steel bars arranged at intervals.

[0074] The first reinforcement member 102 and the second reinforcement member 103 respectively include a plurality of U-shaped steel bars arranged at intervals. The U-shaped steel bars have high bending strength and stability, and provide stable structural performance when constructing the channel reinforcement member of the ship ladder main body 100. The U-shaped steel bars are arranged at intervals, which not only ensures the strength of the ship ladder main body 100, but also reduces the overall weight to a certain extent.

[0075] like Figure 1 , Figure 3 As shown, in an optional embodiment, the first reinforcement member 102 further includes a plurality of bulb flat steels 104 and / or angle steels 105 arranged at intervals between adjacent U-shaped steel bars.

[0076] The first reinforcement 102 also includes a plurality of bulb flat steels 104 and / or angle steels 105 arranged at intervals between adjacent U-shaped steel bars. The bulb flat steel 104 is a flat steel with a circular cross section, and its two ends are usually spherical to provide additional strength and stability, while reducing welding points, and facilitating installation and maintenance. The angle steel 105 is a steel with an L-shaped cross section, which is often used to construct the corners or connection points of the structure to enhance the stability of the connection. By adding the bulb flat steel 104 and the angle steel 105, not only the structural strength of the first reinforcement 102 is enhanced, but also the overall rigidity of the ship ladder main body 100 is improved. The bulb flat steel 104 and the angle steel 105 work together with the U-shaped steel bars to form a solid grid structure, which can effectively disperse the load and reduce local stress concentration, thereby extending the service life of the ship ladder main body 100. It can not only withstand various loads during the berthing of ships and the transfer of personnel and materials, but also adapt to the dynamic changes in the marine environment, ensure the safety and reliability of the ship ladder, and take into account strength, stability and economy.

[0077] It should be noted that siderails are provided on the main body 100 of the ladder to improve the safety of the passage formed on the main body 100 of the ladder, and wire tubes for accommodating and protecting data cables are also arranged on the main body 100 of the ladder and on the siderails.
