Description

Technical Field

[0001] This invention relates to the field of hydraulic equipment technology, and in particular to a floating bridge structure for rapid docking under high sea conditions. Background Technology

[0002] A floating bridge is a special type of bridge that can float on water, connecting two land or water structures. Floating bridges have a wide range of applications, including military, civilian, industrial, and tourism sectors.

[0003] The research background of offshore floating bridges can be viewed from the following aspects:

[0004] 1. Military applications: Floating bridges can play an important role in naval operations, enabling the rapid deployment of defensive facilities, mobile forces, and the transport of supplies, thereby improving combat efficiency and effectiveness.

[0005] 2. Civilian Applications: Floating bridges can be used to connect two islands or facilities on the water, facilitating transportation and the delivery of goods. Furthermore, floating bridges can be used to host various water activities and exhibitions, enhancing the cultural and entertainment atmosphere of a city.

[0006] 3. Industrial applications: Floating bridges can be used to construct industrial facilities such as offshore wind power and offshore oil platforms, facilitating the transportation and maintenance of equipment.

[0007] 4. Environmental protection: Floating bridges can be used to build marine waste disposal stations, marine ecological protection areas, etc., to protect the marine environment and ecosystem.

[0008] Therefore, the research and application of floating bridges at sea have significant practical implications and promising development prospects.

[0009] In existing technologies, due to the complex and changeable marine environment, floating bridges are easily affected by wind, waves, and swells. When docking floating bridges, a large amount of manpower is required, posing significant safety hazards. Furthermore, manual docking is often difficult to achieve precisely due to factors such as sea conditions, resulting in docking difficulties and low efficiency. Traditional end-to-end docking, splicing docking, and locking docking methods lack flexibility and are prone to problems such as tilting and capsizing of the floating bridge, causing huge economic losses and safety accidents. Traditional docking methods lack rotatable and flexibly detachable floating bridge connecting plates, often making the installation and dismantling of the floating bridge very difficult and inefficient. To address these problems, this application proposes a solution. Summary of the Invention

[0010] Purpose of the invention: The purpose of this invention is to provide a floating bridge structure that can be quickly docked under high sea states, which can efficiently complete the docking between floating bridges, while being simple to operate and having low safety risks.

[0011] Technical solution: The present invention provides a floating bridge structure for rapid docking under high sea states, comprising two docking floating bridge bodies, characterized in that: the two docking floating bridge bodies are provided with a quick connection structure on the docking end face, the quick connection structure comprising an active docking structure and a passive docking structure, wherein the modified rubber ring in the active docking structure impacts the impact rod in the passive docking structure, driving the pin to penetrate the modified rubber ring in the active docking structure and the release pin plate and locking pin plate in the passive docking structure, thereby completing the docking;

[0012] The two docking pontoon bridge bodies are equipped with flip-up fast pontoon bridge connecting plates on the docking bridge surface. The flip-up fast pontoon bridge connecting plates rotate by a connecting plate pivot, which is made of reinforced steel bars. Adjustable handles are provided on the side of the flip-up fast pontoon bridge connecting plates.

[0013] Preferably, the active docking structure includes a fixed steel plate with a rectangular opening cut out on its surface. A rubber ring R-arc baffle is installed on the rectangular opening. Rubber ring upper and lower baffles are mounted on the upper and lower rubber ring baffles. An arc-shaped opening is cut out in the middle of the upper and lower rubber ring baffles. A small R-arc plate is installed on the arc-shaped opening below the rubber ring R-arc baffle. A rubber ring pin lower baffle is installed below the small R-arc plate.

[0014] Preferably, a modified rubber ring is inserted into the groove of the rubber ring R-arc baffle, and a pull rod-type pin is inserted into the arc-shaped opening to fix the modified rubber ring.

[0015] Preferably, the passive docking structure includes a fixed steel plate with horizontal elongated openings arranged parallel to each other on the top and bottom of the fixed steel plate. Vertical elongated openings are arranged between the horizontal elongated openings. A release plate is installed in the upper horizontal elongated opening, a locking plate is installed in the lower horizontal elongated opening, and an impact rod is installed in the vertical elongated opening.

[0016] Preferably, a trigger block control structure is mounted above the de-pin plate. The trigger block control structure includes a rectangular box with a rectangular groove in the middle. Rotatable steel bars are provided near the bottom and top of the rectangular groove. A cylindrical gear and a gear are fitted around the outer ring of the rotatable steel bars. The cylindrical gear is inside the rectangular groove, and the gear is outside the rectangular groove, closely attached to the side wall of the rectangular box. The gears located on the top and bottom outer walls of the rectangular groove are not on the same side.

[0017] A rack is provided above the cylindrical gear located at the bottom of the rectangular groove. The rack meshes with the cylindrical gear. A lower movable pin is mounted above the rack. As the rack moves, the lower movable pin is slidably connected to a spring.

[0018] A rack is provided below the cylindrical gear located at the top of the rectangular groove. The rack meshes with the cylindrical gear. An upper movable pin is fitted below the rack. The front end of the upper movable pin is a sliding pin retainer ring. As the rack moves, the upper movable pin is slidably connected to the spring.

[0019] Preferably, the gears located on the top and bottom outer walls of the rectangular groove are respectively fitted with an upper pawl and a lower pawl, the lower pawl being connected to a trigger block, and the trigger block being mounted on the impact rod.

[0020] Preferably, a sliding groove is provided on the end face of the rectangular groove facing the active docking structure, and a limiting block is provided in the sliding groove to slide up and down along the sliding groove. When the pin body has not fallen, the limiting block is located on the end face of the sliding pin retaining ring, thereby limiting the sliding pin retaining ring.

[0021] Preferably, a pin guide sleeve is mounted above the pin release plate, and a pin body is mounted above the pin guide sleeve. A round hole is drilled at a certain position from the bottom of the pin body. When the pin body is not falling, a lower movable pin extends into the round hole to fix the pin body.

[0022] Preferably, the impact rod is fitted with a double-ended bolt on its rear side, and the double-ended bolt is connected to the fixing steel plate by two small springs.

[0023] Preferably, protective structures are provided at the edges of both sides of the floating bridge body, and anti-collision pads are provided on the connecting end faces of the two connected floating bridge bodies.

[0024] Beneficial effects:

[0025] (1) This application realizes the rapid docking of two floating bridge bodies. Only when the improved rubber ring of the active docking structure of one floating bridge body touches the impact block of the passive docking structure of the other floating bridge body can the pin be triggered to fall and insert into the improved rubber ring to fix the structure and achieve rapid and efficient docking. This docking method effectively reduces the difficulty of manual docking operation and solves the safety hazards and inefficiency problems caused by manual docking under high sea conditions.

[0026] (2) This application uses a flip-type quick floating bridge connecting plate. The side of the floating bridge connecting plate is equipped with an adjustable handle. The position of the handle can be adjusted arbitrarily by adjusting the knob. After the floating bridge body is docked, the floating bridge connecting plate can be easily flipped with a small amount of manpower to complete the bridge plate laying. This flip-type floating bridge connecting plate is suitable for high sea states. When the wind and waves are large and the water body is floating, the bridge plate laying can be achieved well. Due to the left and right movement constraint of the improved rubber ring and the up and down floating constraint of the release plate and the locking plate, the displacement range of the floating bridge connecting plate is not large under high sea states. This ensures both the flexibility and stability of the floating bridge connecting plate. It can basically ensure that the two floating bridge bodies are in a relatively horizontal position and has high stability.

[0027] (3) By reinforcing the protective structure at the edge of the floating bridge, this application can effectively prevent vehicles from falling into the sea. Furthermore, the improved rubber ring provides flexibility for the left and right movement of the floating bridge, and the release plate and locking plate provide flexibility for the up and down movement of the floating bridge. This ensures that the overall structure of the floating bridge will not overturn or break under high sea conditions, thus greatly ensuring the safety of vehicles traveling on the floating bridge.

[0028] (4) This application avoids collisions between the two floating bridge structures due to sea waves, which would otherwise damage the quick connection structure and the floating bridge. The anti-collision pads can effectively prevent and reduce structural damage caused by impacts, and greatly extend the service life of the floating bridge structure. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] See Figures 1 to 15 In this embodiment, two floating bridge bodies 1 are included. The two edges of the floating bridge bodies 1 are reinforced with protective structures 39, which can prevent passing vehicles from falling and improve their safety.

[0049] In this embodiment, each floating bridge body 1 has three slots 35 cut into its side. A fixing steel plate 8 is fitted into one of the three slots 35 of one of the floating bridge bodies 1. The surface of the fixing steel plate 8 has a hollowed-out rectangular opening. A rubber ring R-arc baffle 11 is installed in the rectangular opening. Rubber ring upper and lower baffles 10 are installed above and below the rubber ring R-arc baffle 11. An arc-shaped opening is cut out in the middle of the rubber ring upper and lower baffles 10. A small R-arc plate 12 is installed in the arc-shaped opening below the R-arc baffle 11. A rubber ring pin lower baffle 13 is installed below the small R-arc plate 12. A modified rubber ring 14 is inserted into the groove of the rubber ring R-arc baffle 11, and a pull rod-type pin 9 is inserted into the arc-shaped opening to fix the modified rubber ring 13. This structure can effectively fix the modified rubber ring 13, and the contact area of ​​the modified rubber ring 13 is larger, making it easier to touch the impact rod 15, causing the pin 18 to fall off, thus achieving the connection between the two floating bridge bodies 1.

[0050] In this embodiment, a fixing steel plate 8 is installed in the three slots 35 of another floating bridge body 1. A horizontal elongated opening is cut out at a certain distance from the top and bottom of the fixing steel plate 8. A vertical elongated opening is also cut between the two horizontal elongated openings. A release pin plate 17 and a locking pin plate 16 are installed in each of the two horizontal elongated openings, and an impact rod 15 is inserted into the vertical elongated opening. A trigger block 27 is installed on the right side wall of the impact rod 15. A double-headed bolt 25 is connected to the fixing steel plate 8 via a small spring 26 on the rear side of the impact rod 15. A trigger block control structure and a pin guide sleeve 19 are installed above the release pin plate 17.

[0051] In this embodiment, the trigger block control structure includes a rectangular box with a rectangular groove in the middle. A rotatable steel bar 38 is provided near the bottom and near the top of the rectangular groove. A cylindrical gear 30 and a gear 23 are fitted around the outer ring of the rotatable steel bar 38. The cylindrical gear 30 is inside the rectangular groove, and the gear 23 is outside the rectangular groove, closely attached to the side wall of the rectangular box. The gear 23 located on the top and bottom outer walls of the rectangular groove is not on the same side.

[0052] A rack 31 is provided above the cylindrical gear 30 located at the bottom of the rectangular groove. The rack 31 meshes with the cylindrical gear 30. A lower movable pin 32 is mounted above the rack 31. As the rack 31 moves, the lower movable pin 32 is slidably connected to the spring 21.

[0053] A rack 31 is provided below the cylindrical gear 30 located at the top of the rectangular groove. The rack 31 meshes with the cylindrical gear 30. An upper movable pin 20 is mounted below the rack 31. The front end of the upper movable pin 20 is a sliding pin retainer 24. As the rack 31 moves, the upper movable pin 20 is slidably connected to the spring 21.

[0054] In this embodiment, the gears 23 located on the top and bottom outer walls of the rectangular groove are respectively engaged with an upper pawl 28 and a lower pawl 22. The lower pawl 22 is connected to a trigger block 27, which is mounted on the impact rod 15.

[0055] In this embodiment, a sliding groove 29 is provided on the end face of the rectangular groove facing the active docking structure. A limiting block 33 is provided in the sliding groove 29 and slides up and down along the sliding groove 29. When the pin 18 has not fallen, the limiting block 33 is located on the end face of the sliding pin retaining ring 24 and limits the sliding pin retaining ring 24.

[0056] In this embodiment, a pin guide sleeve 19 is mounted above the pin release plate 17, and a pin body 18 is mounted above the pin guide sleeve 19. A round hole 34 is drilled at a certain position from the bottom of the pin body 18. When the pin body 18 is not falling, a lower movable pin 32 extends into the round hole 34 to fix the pin body 18.

[0057] In this embodiment, four reversible fast-connecting bridge panels 2 are provided at the bridge deck connection of the floating bridge body 1. The connecting plate pivot 7 is reinforced with steel bars. Adjustable horizontal handles 4 and adjustable vertical handles 5 are provided on the sides of the reversible fast-connecting bridge panels 2. Anti-collision pads 3 are provided on the sides of the floating bridge body. The four reversible fast-connecting bridge panels 2, together with the connecting plate pivot 7, allow for rapid reversing and laying of the bridge panels with less manpower. The adjustable horizontal handles 4 and adjustable vertical handles 5 on the sides can be adjusted by adjusting the knob 36 to adjust the position of the handles 37 of the horizontal handles 4 and the vertical handles 5, achieving a faster, more efficient, and safer reversing of the floating bridge connecting panels 2. Ultimately, a floating bridge structure for rapid docking under high sea states is achieved.

[0058] In this embodiment, during operation, the modified rubber ring 13 strikes the impact rod 15, which in turn drives the left trigger block 27. The lower pawl 22 on the trigger block 27 disengages from the gear 23 under the action of the trigger block 27. After losing the fixing force of the lower pawl 22 and the gear 23, the lower movable pin 32 slides backward under the elastic force of the spring 21. The slide rail is a structure composed of a cylindrical gear 30 and a rack 31. At this time, the pin 18 loses the fixing force of the lower movable pin 32 and will slide along... The guide sleeve 19 slides down, passing through the release plate 17, the locking plate 16, and the modified rubber ring 13, forming a connection between the two floating bridge bodies 1. During the descent of the pin 18, the structure at the top of the pin 18 causes the limiting block 33 to slide downwards along the slide groove 29. At this time, the sliding pin retaining ring 24 loses its limiting position, and the upper movable pin 20 slides rapidly out along the slide rail under the force of the spring 21, causing the sliding pin retaining ring 24 to lock onto the top of the pin 18, providing a fixing function. The connection between the two floating bridge bodies 1 is then officially completed. This contact-type connection method effectively solves the inefficiency of manual docking. In higher sea states, manual docking is difficult to achieve, while this contact-type connection method is simple, efficient, and easy to implement. Furthermore, the modified rubber ring 14 and the pin 18 are the main connecting bodies, giving the two floating bridge bodies 1 a certain degree of flexibility. In higher sea states, they are less prone to capsizing or breaking, providing high safety.

[0059] In practical use, under high sea states, the rapid docking of two floating bridge bodies 1 enables emergency transport of maritime supplies. First, 2 to 4 crew members are assigned to each floating bridge body 1. They depart from the shore and sail towards the docking location. Upon arrival, the floating bridge body with the passive docking structure remains stationary, while the floating bridge body with the active docking structure sails towards it. This causes the modified rubber ring 14 on the stationary floating bridge body to contact the impact rod 15 on the stationary floating bridge body. Upon contact, the pin 18 falls and connects with the modified rubber ring 14, and the sliding pin retaining ring 24 slides out, locking the top of the pin 18. The rapid connection of the two floating bridge bodies 1 is completed. The next step is the laying of the reversible rapid floating bridge connecting plates 2. One crew member adjusts the adjustment knob 36 to find a suitable angle, holds the handle 37, and flips it upwards, while another crew member assists in the flipping. First, the two outer reversible rapid floating bridge connecting plates 2 are flipped, and then the two inner reversible rapid floating bridge connecting plates 2 are flipped. This allows for the rapid, safe, and efficient laying of the plank bridge, ultimately achieving a floating bridge structure that can be quickly connected under high sea conditions.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of a floating bridge structure for rapid docking under high sea states. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
