Description

Technical Field

[0001] This utility model relates to the field of floating bridge construction technology, and in particular to a floating bridge that can be constructed quickly. Background Technology

[0002] In scenarios such as water conservancy project construction, emergency natural disaster relief, and military strategic deployment, rapidly deployable pontoon bridges play an irreplaceable role as important temporary water transportation facilities. In emergencies such as bridges being destroyed by floods or the need for rapid river crossings during wartime, pontoon bridges can be quickly erected to ensure the timely passage of personnel, supplies, and vehicles, which is crucial for improving rescue efficiency and the smooth progress of military operations.

[0003] Existing rapid-assembly floating bridges generally use a single bolt to connect the modules, which are then tightened with nuts to secure them. This method is widely used due to its advantages of convenient operation and controllable cost. For anti-slip treatment, simple textured patterns are usually set on the surface of the bridge deck; for protection against external impacts, some floating bridges rely solely on the toughness of the main material or lay a layer of ordinary rubber pads on the surface.

[0004] However, the traditional floating bridge relies on a single bolt connection method, which is prone to loosening or even falling off after long-term exposure to external forces such as water flow impact and vehicle vibration, leading to failure of the connection between modules. At the same time, due to the lack of an effective buffer structure, it cannot absorb and disperse energy in time when faced with large impact forces such as collisions, making the floating bridge structure easy to be damaged under impact. It is difficult to meet the requirements of stability and reliability of floating bridges in complex environments. Therefore, a floating bridge that can be quickly assembled is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a floating bridge that can be quickly assembled, aiming to improve the problem that traditional floating bridges in the prior art are easily damaged when subjected to impact due to their single bolt connection and lack of buffer structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-assembly floating bridge includes a floating bridge body, an anti-slip pad fixedly connected to the upper surface of the floating bridge body, a connecting block fixedly connected to the side wall of the floating bridge body, the connecting block being higher on one side and lower on the other, a protective component provided on the side wall of the floating bridge body, and a reinforcement component provided inside the floating bridge body.

[0008] The connecting block is internally threaded with a fixing rod, and the side wall of the fixing rod is threaded with a fixing ring. The side wall of the fixing ring is attached to the bottom of the connecting block. A connecting plate is fixedly connected to one side wall of the fixing rod. A rubber plate is provided on the side wall of the connecting plate. A connecting frame is fixedly connected to the side wall of the connecting plate and the rubber plate. A sleeve is provided on the side wall of the connecting plate. A sliding rod is slidably connected inside the sleeve. A fixing block is fixedly connected to one end of the sliding rod, and a pressing block is fixedly connected to the other end of the sliding rod. A spring is provided inside the sleeve, and the side wall of the spring is fixedly connected between the pressing blocks.

[0009] Furthermore, the reinforcement component includes an aluminum alloy frame, the sidewalls of which are fixedly connected to the interior of the floating bridge body.

[0010] Furthermore, the aluminum alloy frame is provided with closed-cell foam, and the sidewall of the floating bridge body is provided with a polyurethane elastomer coating.

[0011] Furthermore, the sidewall of the polyurethane elastomer coating is provided with a silicone rubber-based coating, and the sidewall of the silicone rubber-based coating is provided with an ultraviolet protection coating.

[0012] Furthermore, the polyurethane elastomer coating is made of polyurethane resin mixed with wear-resistant fillers, which is used to enhance the impact resistance and wear resistance of the floating bridge body surface.

[0013] Furthermore, the silicone rubber-based coating is made by vulcanizing methyl vinyl silicone rubber with added antifouling additives to reduce biofouling.

[0014] Furthermore, the ultraviolet protective coating is formulated by mixing acrylic resin with nano-level ultraviolet absorbers to block ultraviolet rays in sunlight and extend the outdoor service life of the pontoon bridge body.

[0015] Furthermore, the side wall of the fixed block is rotatably connected inside the connecting frame, and the side wall of the extrusion block is slidably connected inside the sleeve.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, during construction, the fixing rod passes through the connecting block and the fixing ring is tightened to complete the splicing. After the thread adhesive cures, the two are bonded together, realizing the splicing of the floating bridge body 1 without loosening. The anti-slip pad increases friction to ensure safety. When impacted, the rubber plate buffers the impact, and the sliding rod slides in the sleeve to drive the compression block to compress the spring to absorb energy. The spring resets and pushes the sliding rod back to its position. The fixing block rotates in the connecting frame to ensure flexible sliding. This solves the problem that traditional floating bridges are easily damaged when impacted by a single bolt connection without a buffer structure. The above technical solution improves the stability of the floating bridge connection and its impact resistance.

[0018] 2. In terms of reinforcement, the aluminum alloy frame enhances strength, closed-cell foam provides buoyancy, polyurethane elastomer coating is impact-resistant and wear-resistant, silicone rubber-based coating reduces biofouling, and ultraviolet protection coating blocks ultraviolet rays. The multi-layer protection extends life and improves durability, solving the problem that traditional floating bridges rely on only a single material, have poor durability, and are easily corroded by the environment. The above technical solutions improve the overall strength of the floating bridge and extend its service life. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4This utility model provides an embodiment of a rapidly assembled floating bridge, comprising a floating bridge body 1. An anti-slip pad 2 is fixedly connected to the upper surface of the floating bridge body 1. The anti-slip pad 2 increases the friction on the upper surface of the floating bridge body 1, thereby preventing pedestrians from slipping and vehicles from skidding. Connecting blocks 3 are fixedly connected to the side walls of the floating bridge body 1. The connecting blocks 3, in conjunction with fixing rods 4, are spliced ​​and fixed together, thereby connecting adjacent floating bridge bodies 1 together, achieving the effect of rapidly assembling a floating bridge. The connecting blocks 3 have one side higher than the other; this structural design facilitates integration with other floating bridge modules. The floating bridge body 1 is assembled with protective components on its side walls and reinforcing components inside. A fixing rod 4 is threadedly connected to the connecting block 3. Thread adhesive is applied to the threaded connection of the fixing rod 4, which cures after the fixing ring 5 is tightened, bonding the fixing rod 4 and the fixing ring 5 together to enhance the anti-loosening effect. A fixing ring 5 is threadedly connected to the side wall of the fixing rod 4, and the fixing ring 5 works in conjunction with the fixing rod 4 to limit and fix it, thereby preventing the fixing rod 4 from loosening and exiting, achieving the effect of enhancing the connection stability of the floating bridge module. The side wall of the fixing ring 5 is attached to the connecting block. At the bottom, a connecting plate 6 is fixedly connected to the side wall of a fixed rod 4. A rubber plate 7 is provided on the side wall of the connecting plate 6. The rubber plate 7 is elastic and used to buffer the impact energy of external forces. A connecting frame 8 is fixedly connected to the side wall of the connecting plate 6 and the rubber plate 7. A sleeve 9 is provided on the side wall of the connecting plate 6. A sliding rod 10 is slidably connected inside the sleeve 9. The sliding rod 10 slides in conjunction with the sleeve 9, thereby driving the compression block 12 to compress the spring 13, achieving the effect of absorbing and dispersing the impact energy of external forces received by the floating bridge body 1. A fixing block 11 is fixedly connected to one end of the sliding rod 10. The fixed block 11 is rotatably connected with the connecting frame 8 to ensure that the slide rod 10 can rotate flexibly during the sliding process. The other end of the slide rod 10 is fixedly connected to the pressing block 12. The sleeve 9 is equipped with a spring 13. The spring 13 works with the pressing block 12 to perform elastic reset, thereby pushing the slide rod 10 back to the initial position after absorbing and dispersing the impact energy, achieving a continuous buffering effect. The side wall of the spring 13 is fixedly connected between the pressing blocks 12, the side wall of the fixed block 11 is rotatably connected inside the connecting frame 8, and the side wall of the pressing block 12 is slidably connected inside the sleeve 9.

[0029] Reference Figures 5-6The reinforcement components include an aluminum alloy frame 14, whose sidewalls are fixedly connected to the interior of the floating bridge body 1. Closed-cell foam 15 is installed inside the aluminum alloy frame 14. The aluminum alloy frame 14, in conjunction with the closed-cell foam 15, provides structural reinforcement and buoyancy reserve, thereby enhancing the strength and rigidity of the floating bridge body 1. A polyurethane elastomer coating 16 is applied to the sidewalls of the floating bridge body 1, and a silicone rubber-based coating 17 is applied to the sidewalls of the polyurethane elastomer coating 16. The polyurethane elastomer coating 16, in conjunction with the silicone rubber-based coating 17, provides surface protection, thereby enhancing the impact resistance and wear resistance of the floating bridge body 1 and reducing biofouling, thus extending the service life of the floating bridge. 7. The sidewalls are provided with an ultraviolet protective coating 18. The silicone rubber base coating 17 works in conjunction with the ultraviolet protective coating 18 to provide environmental protection, thereby reducing biological erosion and ultraviolet damage to the floating bridge body 1, and achieving the effect of improving the durability of the floating bridge. The polyurethane elastomer coating 16 is made of polyurethane resin mixed with wear-resistant fillers and is used to enhance the impact resistance and wear resistance of the surface of the floating bridge body 1. The silicone rubber base coating 17 is made of methyl vinyl silicone rubber as the base material and antifouling additives are added and vulcanized to reduce biofouling. The ultraviolet protective coating 18 is formulated by mixing acrylic resin with nano-level ultraviolet absorbers and is used to block ultraviolet rays in sunlight and extend the outdoor service life of the floating bridge body 1.

[0030] Working principle: When building a floating bridge, the adjacent floating bridge bodies 1 can be spliced ​​and fixed by passing the fixing rod 4 through the connecting block 3 and tightening the fixing ring 5. The threaded connection of the fixing rod 4 has thread adhesive, which cures after the fixing ring 5 is tightened, bonding the fixing rod 4 and the fixing ring 5 together and enhancing the anti-loosening effect. The anti-slip pad 2 can increase the friction of the upper surface and ensure passage safety. When the floating bridge is impacted by external force, the rubber plate 7 contacts the buffer first. The sliding rod 10 slides in the sleeve 9 with the movement of the rubber plate 7, driving the compression block 12 to compress the spring 13, absorbing and dispersing the impact energy. When the spring 13 returns to its original position, it pushes the sliding rod 10 back to its original position, achieving continuous buffering. While the sliding rod 10 moves, the fixing block 11 rotates inside the connecting frame 8 to ensure that the sliding rod 10 slides flexibly.

[0031] In terms of reinforcement, the aluminum alloy frame 14 enhances the strength of the pontoon body 1, the closed-cell foam 15 provides buoyancy reserve, the polyurethane elastomer coating 16 enhances the surface's impact and wear resistance, the silicone rubber-based coating 17 reduces biofouling, and the UV protection coating 18 blocks ultraviolet rays. The combined effect of these multiple layers of protection extends the service life of the pontoon and improves its durability.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
