Description

Technical Field

[0001] The invention relates to the technical field of bridge pier anti-collision, and in particular to an aramid skeleton soft multi-stage anti-collision device with rubber coated cloth and a construction method. Background Art

[0002] The bridge pier anti-collision technology is designed to protect the bridge structure from damage caused by external forces such as ship collisions and drifting objects, ensuring bridge safety and smooth traffic. The core lies in the design and implementation of effective protective measures, including but not limited to the installation of anti-collision casings, the installation of anti-collision buffer devices, the use of energy-absorbing materials, and the optimization of bridge pier shapes to improve hydrodynamic characteristics. These measures can effectively disperse and absorb impact energy, reduce the force directly acting on the bridge piers, and thus enhance the overall stability and durability of the bridge. In addition, through the real-time monitoring system, potential collision risks can be warned in a timely manner, further improving the safety management level of the bridge. The continuous advancement of bridge pier anti-collision technology has brought a higher level of safety protection to the field of bridge engineering and is an indispensable and important part of modern bridge construction.

[0003] The existing anti-collision technology for bridge piers mainly uses soft bodies to absorb impacts. When encountering a larger hull, it will result in insufficient energy absorption, thus causing damage to the bridge piers. Summary of the invention

[0004] The purpose of the present invention is to provide an aramid skeleton soft multi-stage anti-collision device with rubber coated cloth and a construction method, aiming to be able to perform impact anti-collision on various hulls, so that the anti-collision effect is better.

[0005] To achieve the above-mentioned objectives, in a first aspect, the present invention provides an aramid skeleton soft multi-stage anti-collision device with rubber-coated cloth, comprising an installation component, an anti-collision component and an adjustment component, wherein the installation component comprises a first mounting ring, a second mounting ring and a plurality of mounting bolts, and the first mounting ring and the second mounting ring are fixed by the mounting bolts to form a ring-shaped installation on the bridge pier; the anti-collision component comprises a protective software, a rubber-coated cloth and a buffer shell structure, the protective software is arranged on the outside of the first mounting ring and the second mounting ring, the rubber-coated cloth is arranged on the outside of the protective software, the buffer shell structure is arranged on the outside of the rubber-coated cloth, and the adjustment component is arranged at the bottom of the first mounting ring for adjusting the orientation of the buffer shell structure.

[0006] Wherein, the first mounting ring comprises a ring body and a floating plate, and the floating plate is arranged at the bottom of the ring body.

[0007] Wherein, the first mounting ring also includes an airbag, a gas generator, a vibration sensor and a controller, the airbag is arranged on the inner side of the ring body, the gas generator is arranged on one side of the airbag, and the controller is connected to the vibration sensor and the gas generator.

[0008] Wherein, the first mounting ring further includes an anti-skid layer, and the anti-skid layer is arranged on one side of the airbag.

[0009] Wherein, the rubber coated cloth comprises a base cloth, a rubber layer and a reinforcement layer.

[0010] Wherein, the buffer shell structure includes a plurality of concave frames, and the plurality of concave frames are nested and arranged, and each two adjacent concave frames are connected by a rod.

[0011] Wherein, the buffer shell structure further comprises a connecting rubber cloth layer, and the connecting rubber cloth layer is wound between every two adjacent concave frames.

[0012] In a second aspect, the present invention also provides a construction method of an aramid skeleton soft multi-stage anti-collision device with a rubber-coated cloth, comprising: designing a buffer shell structure according to the size of the bridge pier and the expected impact force, pre-processing the aramid skeleton and preparing the rubber-coated cloth;

[0013] The aramid skeleton is welded into shape in the factory and connected to the rubber-coated cloth;

[0014] Fix the soft body to one side of the rubber-coated cloth;

[0015] The first mounting ring, the second mounting ring and the soft body are connected to obtain a preassembled ship collision prevention device;

[0016] The preassembled anti-ship collision device is fixed on the target bridge pier and connected to the bridge pier through multiple mounting bolts.

[0017] The present invention provides an aramid skeleton soft multi-stage anti-collision device with rubber-coated cloth and a construction method. In this embodiment, the mounting assembly is the basis of the entire anti-collision device, and is composed of a first mounting ring, a second mounting ring, and a plurality of mounting bolts. The first mounting ring and the second mounting ring are respectively designed to be semicircular or arc-shaped, which can closely fit the contour of the bridge pier and provide a stable support point. The two mounting rings are fixed together by precise adjustment and using mounting bolts to form a complete ring structure, which tightly wraps the bridge pier, ensuring that there is no looseness between the anti-collision device and the bridge pier, thereby enhancing the overall stability.

[0018] The anti-collision component is the core part of the anti-collision device, which consists of three parts: protective software, rubber-coated cloth and buffer shell structure. The protective software adopts high-density polyurethane foam or other high-performance energy-absorbing materials, which can effectively absorb the impact energy and reduce the impact of the impact force on the bridge pier. The rubber-coated cloth covers the outer layer of the protective software, which not only increases the friction coefficient of the surface and improves the wear resistance, but also has a certain elasticity, which can further disperse the impact force when it is hit and protect the internal structure from damage. The buffer shell structure is located in the outermost layer and is made of high-strength steel, so that it can be deformed during impact, thereby absorbing more severe impacts. If it is a larger hull during impact, the direction of the buffer shell is changed by adjusting the component, so that it faces the hull, and the energy is absorbed by the combination of the buffer shell structure and the protective software to better reduce the impact. When the hull is small, the energy is directly absorbed by the protective software, so that various hulls can be impact-proofed, so that the anti-collision effect is better.

[0030] First embodiment

[0031] See also Figure 1 to Figure 6The present invention provides an aramid skeleton soft multi-stage anti-collision device with a rubber coated cloth 108, comprising an installation component 101, an anti-collision component 102 and an adjustment component 103, wherein the installation component 101 comprises a first installation ring 104, a second installation ring 105 and a plurality of installation bolts 106, wherein the first installation ring 104 and the second installation ring 105 are fixed by the installation bolts 106 to form a ring-shaped installation on the bridge pier; the anti-collision component 102 comprises a protective soft body 107, a rubber coated cloth 108 and a buffer shell structure 109, wherein the protective soft body 107 is arranged on the outside of the first installation ring 104 and the second installation ring 105, the rubber coated cloth 108 is arranged on the outside of the protective soft body 107, the buffer shell structure 109 is arranged on the outside of the rubber coated cloth 108, and the adjustment component 103 is arranged at the bottom of the first installation ring 104 for adjusting the orientation of the buffer shell structure 109.

[0032] In this embodiment, the mounting assembly 101 is the basis of the entire anti-collision device, and is composed of a first mounting ring 104, a second mounting ring 105, and a plurality of mounting bolts 106. The first mounting ring 104 and the second mounting ring 105 are respectively designed to be semicircular or arc-shaped, which can closely fit the contour of the bridge pier and provide a stable support point. The two mounting rings are fixed together by precise adjustment and using mounting bolts 106 to form a complete ring structure, which tightly wraps the bridge pier, ensuring that there is no looseness between the anti-collision device and the bridge pier, thereby enhancing the overall stability. The anti-collision assembly 102 is the core part of the anti-collision device, and is composed of three parts: a protective software 107, a rubber-coated cloth 108, and a buffer shell structure 109. The protective software 107 is made of high-density polyurethane foam or other high-performance energy-absorbing materials, which can effectively absorb impact energy and reduce the impact of impact force on the bridge pier. The rubber-coated cloth 108 covers the outer layer of the protective software 107, which not only increases the friction coefficient of the surface and improves the wear resistance, but also has a certain elasticity, which can further disperse the impact force when it is hit and protect the internal structure from damage. The buffer shell structure 109 is located at the outermost layer and is made of high-strength steel, so that it can be deformed during impact, thereby absorbing more severe impacts. When impacting a larger hull, the direction of the buffer shell is changed by adjusting the component 103 so that it faces the hull, and energy is absorbed by the combination of the buffer shell structure 109 and the protective soft body 107 to better reduce the impact. When the hull is small, energy is directly absorbed by the protective soft body 107, so that various hulls can be impact-proofed, so that the anti-collision effect is better.

[0033] The first mounting ring 104 includes a ring body 110 and a floating plate 111 . The floating plate 111 is disposed at the bottom of the ring body 110 .

[0034] The design of the first mounting ring 104 reflects the attention to detail and the ultimate pursuit of safety performance. In addition to the basic ring body 110 structure, it is also equipped with a floating board 111, which is arranged at the bottom of the ring body 110. This floating board 111 can not only significantly improve the buoyancy of the anti-collision device and ensure its stability in the water, but also reduce the shaking caused by the water flow to a certain extent, and enhance the overall wind and wave resistance.

[0035] The first mounting ring 104 also includes an airbag 112, a gas generator 113, a vibration sensor 114 and a controller 115. The airbag 112 is arranged on the inner side of the ring body 110, the gas generator 113 is arranged on one side of the airbag 112, and the controller 115 is connected to the vibration sensor 114 and the gas generator 113.

[0036] The first mounting ring 104 also integrates high-tech components such as an airbag 112, a gas generator 113, a vibration sensor 114 and a controller 115. The airbag 112 is cleverly arranged on the inner side of the ring body 110. When the vibration sensor 114 detects abnormal vibration or potential impact signals, the controller 115 quickly activates the gas generator 113 to quickly fill the airbag 112 so that it can form a close contact with the bridge pier, so that the buffer shell structure 109 does not deflect during impact.

[0037] The first mounting ring 104 further includes an anti-slip layer 116 , which is disposed on one side of the airbag 112 .

[0038] The addition of the anti-skid layer 116 further enhances the friction between the anti-collision device and the bridge pier.

[0039] The rubber-coated cloth 108 includes a base cloth 117 , a rubber layer 118 and a reinforcement layer 119 .

[0040] The rubber-coated cloth 108 serves as the outer layer of the protective software 107 and adopts a multi-layer composite structure, including a base cloth 117, a rubber layer 118 and a reinforcement layer 119, which ensures excellent wear resistance, weather resistance and mechanical properties and can withstand the test in complex environments.

[0041] The buffer shell structure 109 includes a plurality of concave frames 120 , which are nested in each other, and each two adjacent concave frames 120 are connected by a rod.

[0042] The design of the buffer shell structure 109 is also unique, adopting a nested structure of multiple concave frames 120. Each concave frame 120 is connected by rods to form a protective barrier that is both strong and flexible.

[0043] The buffer shell structure 109 further includes a connecting rubber cloth layer 121 , and the connecting rubber cloth layer 121 is wound between every two adjacent concave frames 120 .

[0044] The connecting rubber cloth layer 121 is wound between every two adjacent concave frames 120, which not only enhances the integrity of the structure but also improves the ability to absorb external impact.

[0045] An extrusion plate 122 is further provided on the outer side of the buffer shell structure 109 , and the anti-slip studs are further provided on the extrusion plate 122 .

[0046] The provision of the extrusion plate 122 and the anti-slip spikes further enhances the stability of the anti-collision device when it contacts external objects, thereby ensuring the safety protection effect in high-speed collision situations.

[0047] The regulating assembly 103 includes a driver 123 , a blade 124 and a mounting seat 125 . The mounting seat 125 is disposed on one side of the second connecting ring. The driver 123 is disposed on the mounting seat 125 . The blade 124 is fixedly connected to the output end of the driver 123 .

[0048] The design of the adjustment component 103 integrates the driver 123, the blade 124 and the mounting seat 125, and realizes the precise control of the orientation of the buffer shell structure 109. The mounting seat 125 is firmly fixed on one side of the second connecting ring, and the driver 123 accurately controls the angle change of the blade 124. By changing the direction of the blade 124 relative to the water flow, the adjustment component 103 can actively adjust the posture of the anti-collision device so that the buffer shell structure 109 can be better aligned with the hull.

[0049] Second embodiment

[0050] See also Figure 7 On the basis of the first embodiment, the present invention further provides a construction method of an aramid skeleton soft multi-stage anti-collision device having a rubber coated cloth 108, comprising:

[0051] S201 designs a buffer shell structure 109 according to the bridge pier size and the expected impact force, pre-processes an aramid skeleton and prepares a rubber coating cloth 108;

[0052] First, based on the precise measurement of the bridge pier dimensions and the scientific assessment of the expected impact force, the design team began to develop a detailed buffer shell structure 109 plan. This stage not only involves an in-depth analysis of structural mechanics, but also takes into account the selection of materials, cost control, and construction feasibility. After the design is completed, the material preparation phase begins, including the prefabrication of the aramid skeleton and the preparation of the rubber-coated cloth 108. The aramid skeleton needs to be precisely cut and preliminarily formed according to the requirements of the design drawings to ensure that the size and shape of each component meet the standards. The preparation of the rubber-coated cloth 108 requires strict control of the coating thickness and uniformity to ensure that it has good waterproof, wear-resistant and anti-aging properties.

[0053] S202 welds the aramid skeleton into shape in the factory and connects it to the rubber coated cloth 108;

[0054] In a professional factory, technicians carefully weld the prefabricated aramid skeleton to form a stable buffer shell structure 109. This process requires the use of advanced welding technology and equipment to ensure welding quality and prevent cracks or deformation of the structure. Subsequently, the rubber coating cloth 108 is connected to the aramid skeleton. This step requires high-precision positioning and fastening to ensure that the rubber coating cloth 108 can be firmly wrapped around the outside of the aramid skeleton to form an effective protective layer.

[0055] S203 fixes the software on one side of the rubber coated cloth 108;

[0056] After the aramid skeleton is connected to the rubber coated cloth 108, the next step is to fix the software (i.e., the protective software 107) to one side of the rubber coated cloth 108. The installation of the software must ensure that its position is accurate and tightly combined with the rubber coated cloth 108 to form a seamless connection to give full play to its energy absorption and shock reduction function. This process may involve the use of special adhesives or mechanical fixing methods to ensure that the software will not fall off or shift when it is hit.

[0057] S204: Connect the first mounting ring 104, the second mounting ring 105 and the software to obtain a pre-assembled ship collision prevention device;

[0058] With the software fixed, the next task is to connect the first mounting ring 104, the second mounting ring 105 with the software to form a pre-assembled anti-collision device. The focus of this stage is to ensure the correct docking and fastening between the components to form a stable and fully functional whole. The pre-assembled anti-collision device must also undergo rigorous inspection before leaving the factory to ensure that all components are in the best condition and meet the design requirements.

[0059] S05 fixes the preassembled anti-ship collision device on the target bridge pier and connects it to the bridge pier through a plurality of mounting bolts 106 .

[0060] Finally, the pre-assembled anti-collision device is transported to the construction site and fixed on the target bridge pier. This step requires the construction team to have high professional skills and rich on-site experience, to be able to accurately judge the actual condition of the bridge pier, and to reasonably arrange the installation sequence and method. The anti-collision device is connected to the bridge pier through multiple mounting bolts 106 to ensure that the anti-collision device is firmly fixed on the bridge pier and can withstand the expected impact force. During the installation process, it is also necessary to check the tightness of each connection point to ensure the stability and safety of the entire anti-collision device.

[0061] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
