Description

Technical Field

[0001] This utility model relates to the field of anti-collision technology for opening bridges, specifically an anti-collision structure for opening bridges. Background Technology

[0002] As a crucial node in transportation networks, the safety performance of bridges directly affects traffic flow and the safety of life and property. In waterways and other aquatic environments, bridge piers face the potential risk of ship collisions, highlighting the increasing limitations of traditional anti-collision structures.

[0003] Traditional bridge collision protection structures often employ rigid materials (such as concrete and steel) or single airbag structures. When a ship collides with a bridge, rigid structures cannot effectively absorb impact energy, easily leading to damage to bridge piers or ship structural failure. While fixed airbags can provide some cushioning, they cannot guide the ship away from the collision direction, resulting in significant frontal impact loads. Furthermore, airbags are prone to rupture with prolonged impacts, leading to high maintenance costs. In addition, existing collision protection structures often rely on single buffer components, concentrating impact forces during a collision and making them ill-suited for impact scenarios involving ships of varying tonnages and speeds. For example, airbags may rupture due to a sudden increase in internal pressure during a severe impact, lacking pressure transmission and secondary cushioning mechanisms, thus reducing the reliability of the collision protection. Utility Model Content

[0004] The purpose of this invention is to provide an anti-collision structure for an opening bridge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an openable bridge anti-collision structure, including a bridge column and two sets of arc-shaped clamping blocks 1 and 2 arranged on the outer side of the bridge column. Connecting rods 1 and 2 are evenly arranged on the outer side of the two sets of arc-shaped clamping blocks 1 and 2 respectively. A fixing frame is provided at the top of each of the connecting rods 1 and 2. A support ring is installed on the inner side of the upper and lower fixing frames by bolts. An airbag is installed between the upper and lower fixing frames on the outer side of the support ring by bearings. An inner tube is provided in the center of the airbag. Air holes are evenly arranged on the surface of the inner tube.

[0006] Each of the support rings between adjacent airbag barrels has a cavity inside. A piston is connected to the cavity through a return spring. A push rod is provided on the outside of the piston. One end of the push rod extends to the outside of the support ring and is fitted with a rubber head.

[0007] Preferably, the outer wall of the inner support ring of the airbag barrel is provided with a slot for accommodating the airbag barrel.

[0008] Preferably, each of the airbags is provided with a connecting pipe at the top that is connected to the inner tube, and the other end of the connecting pipe extends into the interior of the adjacent cavity.

[0009] Preferably, each of the connecting rods is equipped with a rotating blade on its top via a column, and a reflector is provided on both sides of each rotating blade.

[0010] Preferably, each of the connecting rods is provided with a hole at the middle position, and the bottom end of the column is provided with a rotating shaft that passes through the hole.

[0011] Preferably, both the outer sides of the arc-shaped clamping block one and the arc-shaped clamping block two are provided with slide rails, and one end of each of the connecting rods one and two is provided with a sliding sleeve that matches the slide rail.

[0012] Preferably, the arc-shaped clamping block one and the arc-shaped clamping block two are combined to form a ring structure, the inner diameter of which matches the outer diameter of the bridge column, and the bolts at both ends of the arc-shaped clamping block one and the arc-shaped clamping block two are detachably connected.

[0013] Compared with the prior art, the opening bridge anti-collision structure provided by this utility model has significant advantages and positive effects, specifically reflected in the following aspects:

[0014] 1. By installing connecting rod one and connecting rod two on the outer side of the bridge pier, and mounting the airbag barrel between the fixed frames on the outer side of the support ring via bearings, the airbag barrel can rotate freely upon impact. This effectively guides the ship away from the collision direction, thereby reducing frontal impact loads and lowering the risk of damage to the bridge and the ship. Compared with traditional fixed anti-collision structures, the rotating airbag barrel design of this invention significantly improves the anti-collision effect.

[0015] 2. A cavity is created inside the support ring between adjacent airbags, and a piston is connected to it via a return spring. A push rod and a rubber head are located on the outside of the piston. When an airbag is impacted, the air pressure inside the airbag is transmitted to the cavity through a connecting pipe, pushing the piston outward. This causes the push rod to extend the rubber head outward, making contact with the colliding vessel. This multiple buffering mechanism further reduces the impact force on top of the initial buffering, providing more reliable collision protection.

[0016] 3. Upon impact, the airbag canister not only disperses the impact force through rotation and multiple cushioning mechanisms, but also prevents the airbag from puncturing due to the increased pressure generated by the impact through its own contraction and deformation. This not only improves the durability of the anti-collision structure, but also extends its service life and reduces maintenance costs.

[0017] 4. Each link is topped with a rotating blade mounted on a column, and reflectors are installed on both sides of the rotating blade. This not only provides a clear warning effect at night or in poor visibility conditions, but also attracts the attention of ship operators through the dynamic display of the rotating blade, further enhancing the safety of the bridge and the ship.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-4 An embodiment of this utility model provides an openable bridge anti-collision structure, including a bridge column 1 and two sets of arc-shaped clamping blocks 12 and 13 arranged on the outer side of the bridge column 1. Connecting rods 3 and 25 are evenly arranged on the outer side of the two sets of arc-shaped clamping blocks 12 and 13 respectively. A slide rail 14 is provided on the outer side of both arc-shaped clamping blocks 12 and 13, and a sliding sleeve 2 matching the slide rail 14 is provided at one end of each connecting rod 3 and 25.

[0025] The arc-shaped clamping block 12 and the arc-shaped clamping block 23 are combined to form a ring structure. The inner diameter of the ring structure matches the outer diameter of the bridge column 1, and the bolts at both ends of the arc-shaped clamping block 12 and the arc-shaped clamping block 23 are detachably connected.

[0026] Arc-shaped clamping blocks 12 and 13 are symmetrically distributed on the upper and lower sides of bridge column 1, respectively. Each set of arc-shaped clamping blocks 12 and 13 consists of two arc-shaped steel plates, the inner diameter of which precisely matches the outer diameter of bridge column 1 to ensure a tight fit. The two ends of arc-shaped clamping blocks 12 and 13 are detachably connected by bolts for easy installation and maintenance.

[0027] Connecting rod 1 (3) and connecting rod 2 (25) are evenly arranged on the outer sides of arc-shaped clamping block 1 (12) and arc-shaped clamping block 2 (13), respectively.

[0028] Each link 1 3 and link 2 25 has a sliding sleeve 2 fixed at one end. The sliding sleeve 2 matches the slide rail 14 to ensure that the link slides smoothly on the slide rail.

[0029] The slide rail 14 is located on the outside of the arc-shaped clamping block 12 and the arc-shaped clamping block 23, providing a sliding path for the slide sleeve 2.

[0030] The slide rail 14 is typically made of wear-resistant materials to ensure stability and reliability during long-term use.

[0031] Each link 1 3 and link 2 25 is equipped with a fixing bracket 10 at its top. The inner side of the upper and lower fixing brackets 10 is equipped with a support ring 5 by bolts. The upper and lower fixing brackets 10 on the outer side of the support ring 5 are connected by a bearing 11 to install an airbag 9.

[0032] The inner support ring 5 of the airbag barrel 9 is provided with slots 6 on the outer wall for accommodating the airbag barrel 9.

[0033] The fixture 10 is designed to provide a stable support structure, ensuring the reliability and durability of the entire device.

[0034] Support rings 5 ​​are bolted to the inner side of the upper and lower fixing frames 10. The support rings 5 ​​are made of high-strength materials to ensure that they are not easily deformed or damaged during use. The bolt connection not only facilitates installation and disassembly but also provides sufficient tightening force to ensure a stable connection between the support rings 5 ​​and the fixing frames 10.

[0035] An airbag 9 is mounted between the upper and lower fixing brackets 10 on the outer side of the support ring 5 via a bearing 11. The bearing 11 allows the airbag 9 to rotate freely within a certain range, thus adapting to different working conditions and load requirements.

[0036] The outer wall of the support ring 5 inside the airbag 9 is provided with a slot 6 for accommodating the airbag 9. The slot 6 is ingeniously designed, its shape matching the outer wall of the airbag 9, which can effectively prevent the airbag 9 from shifting during rotation or vibration. The depth and width of the slot 6 have been precisely calculated to ensure that it provides sufficient support without affecting the normal movement of the airbag 9.

[0037] An inner tube 15 is located in the center of the airbag 9, and air holes 16 are evenly distributed on the surface of the inner tube 15.

[0038] Each of the support rings 5 ​​between adjacent airbag barrels 9 has a cavity 20 inside. Inside the cavity 20, a piston 21 is connected by a return spring 22. A push rod 24 is provided on the outside of the piston 21. One end of the push rod 24 extends to the outside of the support ring 5 and is fitted with a rubber head 7.

[0039] Each airbag 9 has a connecting pipe 8 at its top that is connected to the inner tube 15, and the other end of the connecting pipe 8 extends into the adjacent cavity 20.

[0040] The airbag 9 is the core component of this device, with an inner tube 15 located at its center. Multiple air holes 16 are evenly distributed on the surface of the inner tube 15, allowing gas to flow and ensuring uniform air pressure distribution inside the airbag 9. The outer wall of the airbag 9 is made of high-strength material to ensure its stability and safety under high-pressure environments.

[0041] Adjacent airbags 9 are connected by support rings 5. The support rings 5 ​​have internal cavities 20, which house the piston 21 and its related components. Each support ring 5 is robustly constructed, effectively supporting and separating adjacent airbags 9, ensuring the stability of the entire device.

[0042] A piston 21 is connected to the inside of cavity 20 via a return spring 22. One end of the return spring 22 is fixed to the inner wall of cavity 20, and the other end is connected to piston 21, allowing piston 21 to move freely within cavity 20. The function of the return spring 22 is to return piston 21 to its initial position after it has moved, ensuring the normal operation of the device.

[0043] A push rod 24 is provided on the outer side of the piston 21. One end of the push rod 24 is connected to the piston 21, and the other end extends to the outer side of the support ring 5, with a rubber head 7 installed at the outer end. The function of the rubber head 7 is to reduce friction and impact when the push rod 24 contacts the outside, thus protecting the components of the device.

[0044] Each airbag 9 has a connecting pipe 8 at its top, which is connected to the inner tube 15. The other end of the connecting pipe 8 extends into the adjacent cavity 20, forming a gas passage. Through the connecting pipe 8, the gas inside the airbag 9 can flow to the adjacent cavity 20, achieving pressure equalization and regulation.

[0045] Each link 3 has a rotating blade 19 mounted on its top via a column 17, and each rotating blade 19 has a reflector 18 on both sides.

[0046] The rotating blade 19 rotates when blown by the wind. When paired with the reflector 18, it can reflect sunlight during the day and ship lights at night, attracting the attention of ship operators and further improving the safety of bridges and ships.

[0047] Each link 3 has a hole 4 at its middle position, and the bottom of the column 17 has a rotating shaft 23 that passes through the hole 4.

[0048] A hole 4 is provided at the middle position of the connecting rod 3. The diameter of the hole 4 is slightly larger than the diameter of the rotating shaft 23 so that the rotating shaft 23 can pass through smoothly.

[0049] When this application embodiment is used,

[0050] Initial state: The inner tube 15 inside the airbag barrel maintains internal air pressure balance through the air hole 16, the connecting tube 8 connects the adjacent airbag barrel and the support ring cavity 20, the piston 21 is in the initial position under the action of the return spring 22, and the rubber head 7 of the push rod 24 is flush with the outer wall of the support ring.

[0051] The column 17 at the top of the connecting rod passes through the connecting rod hole 4 via the rotating shaft 23 and is fitted with a rotating blade 19. The reflectors 18 on both sides of the blade are horizontally extended. When there is no external force, the rotating blade rotates slowly under the action of wind, and the reflectors continuously reflect light to achieve dynamic warning.

[0052] Impact occurs: The ship hits the airbag barrel 9. The impact force causes the airbag barrel to rotate around the bearing 11, changing the direction of the ship's collision and converting some of the kinetic energy into rotational kinetic energy, thus reducing the frontal impact load.

[0053] When the direction of a ship collision changes, the ship's side will inevitably come into contact with other airbags 9, forming a regional buffer network and improving the overall reliability of collision avoidance.

[0054] The airbag barrel 9 is deformed by compression, and the internal gas gathers through the air hole 16 in the inner tube to the connecting pipe 8. It then flows into the cavity 20 of the adjacent support ring through the connecting pipe, pushing the piston 21 to move and causing the push rod 24 to extend outward. The rubber head 7 contacts the ship's hull, forming a physical buffer.

[0055] Impact ends: After the ship deviates, the reset spring 22 drives the piston (21) to reset, the push rod 24 retracts, and the air pressure inside the airbag 9 is restored to balance through the connecting pipe 8.
