[0015] Advantages of the present utility model:

[0016] 1. When the bridge anti-collision device is in use, first, the mounting plate is fixedly installed at the designated mounting position of the bridge through the mounting assembly. When the anti-collision frame is impacted by an external vehicle or other object, the impact force first acts on the impact surface. Due to the sliding connection design of the sliding cylinder and the fixed cylinder, the anti-collision frame will drive the sliding cylinder to slide along the fixed cylinder. During this process, the impact force is dispersed and transmitted to the fixed cylinder and the mounting plate. During the sliding process, the shock absorption assembly and the buffer assembly act simultaneously. The shock absorption assembly slows down the transmission speed of the impact force through its elastic or damping characteristics, while the buffer assembly provides an additional buffering effect to reduce the direct action of the impact force on the bridge structure. Through the sliding of the sliding cylinder, the shock absorption of the shock absorption assembly, and the buffering of the buffer assembly, the impact energy is gradually absorbed and dissipated. In this way, it can not only protect the bridge structure from damage but also reduce the rebound and secondary damage of the vehicle or the impact object, thereby improving the use effect of the device for buffering and shock absorption.

Specific embodiments

[0023] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1-5 , the present utility model provides an embodiment: a bridge anti-collision device, including a mounting plate 1, an anti-collision frame 2, an impact surface 3, a sliding cylinder 4, a fixed cylinder 5, a shock absorption assembly, a guiding assembly, a buffering assembly and a mounting assembly; a fixed cylinder 5 is arranged on one side of the mounting plate 1, multiple groups of fixed cylinders 5 are provided, a sliding cylinder 4 is arranged outside the fixed cylinder 5, the sliding cylinder 4 is slidably connected with the fixed cylinder 5, an anti-collision frame 2 is arranged at one end of the sliding cylinder 4, an impact surface 3 is arranged on the side wall of the anti-collision frame 2, a mounting assembly is arranged on the other side of the mounting plate 1, a shock absorption assembly is arranged inside the fixed cylinder 5, guiding assemblies are arranged on both sides of the mounting plate 1, and a buffering assembly is arranged on the side wall of the guiding assembly.

[0025] Please refer to Figure 2, the shock absorption assembly includes a fixed rod 101 and a sliding block 102; a fixed rod 101 is arranged inside the fixed cylinder 5, a sliding block 102 is arranged on the side wall of the fixed rod 101, and the sliding block 102 is slidably connected to the fixed rod 101; the fixed rod 101 is arranged inside the fixed cylinder 5 to serve as a track for the sliding of the sliding block 102 to maintain the stable movement of the sliding block 102. The sliding block 102 is slidably connected to the fixed rod 101. When the anti-collision frame 2 is impacted, the sliding block 102 will move along the fixed rod 101 as the sliding cylinder 4 slides; the shock absorption assembly further includes a shock absorption damper 103, a shock absorption spring 104 and a return spring 105; a shock absorption spring 104 is arranged outside the fixed rod 101. One end of the shock absorption spring 104 is fixedly connected to the bottom of the sliding block 102, and the other end of the shock absorption spring 104 is fixedly connected to the inner wall of the fixed cylinder 5. A shock absorption damper 103 is arranged on the side wall of the fixed rod 101, and a return spring 105 is arranged on the inner wall of the fixed cylinder 5; when the anti-collision frame 2 is impacted by the outside world, the impact force is transmitted to the sliding cylinder 4 through the anti-collision frame 2, causing the sliding cylinder 4 to perform buffer contraction along the fixed cylinder 5. In this process, the impact force is initially dispersed and transmitted to the fixed cylinder 5 and the shock absorption assembly inside it. As the sliding cylinder 4 slides, the sliding block 102 moves along the fixed rod 101. In this process, the shock absorption damper 103 plays a role, generating damping on the movement of the sliding block 102 through its viscous or elastic characteristics, slowing down the sliding speed, thereby prolonging the action time of the impact force and reducing the peak impact force. When the sliding block 102 slides, the connected shock absorption spring 104 is compressed, absorbing and storing part of the impact energy. In this process, the elastic deformation of the shock absorption spring 104 can effectively slow down the transmission of the impact force and disperse and absorb the impact energy. Although the return spring 105 does not directly participate in shock absorption during the impact process, it plays an important role after the impact. Through its elastic restoring force, the return spring 105 helps the sliding block 102 and the sliding cylinder 4 return to the initial position to prepare for the next impact. Through the synergistic effect of multiple shock absorption assemblies, the impact force generated by the impact is effectively dispersed, absorbed and dissipated. In this process, the impact force is gradually weakened, and the impact force on the bridge structure is greatly reduced, thereby protecting the safety and stability of the bridge structure; the guiding assembly includes a guiding rod 201, a guiding block 202 and a guiding groove 203; guiding grooves 203 are opened on both sides of the mounting plate 1, a guiding rod 201 is arranged inside the guiding groove 203, guiding blocks 202 are arranged on the side wall of the guiding rod 201, there are two groups of guiding blocks 202, and the guiding blocks 202 are slidably connected to the guiding rod 201; the guiding rod 201 provides a stable sliding track for the guiding block 202, the guiding block 202 is used to connect and support other components, and the guiding groove 203 is used to accommodate and guide the movement of the guiding rod 201 and the guiding block 202.

[0026] Please refer to Figures 3-5, in this embodiment, the buffer assembly includes a mounting block 301, a mounting hole 302, a scroll spring 303 and a mounting shaft 304; a mounting block 301 is provided on the side wall of the guide block 202, a mounting hole 302 is formed inside the mounting block 301, a mounting shaft 304 is provided inside the mounting hole 302, a scroll spring 303 is provided at one end of the mounting shaft 304, one end of the scroll spring 303 is fixedly connected to one end of the mounting shaft 304, and the other end of the scroll spring 303 is fixedly connected to the inner wall of the mounting hole 302; the mounting block 301 and the mounting hole 302 are used for mounting and fixing other components, the mounting hole 302 is used for accommodating the mounting shaft 304, and the mounting shaft 304 serves as the support point for the scroll spring 303 and the adjusting rod 305. When an external force acts, the scroll spring 303 can deform and store energy, and then release the energy to produce a buffering effect; the buffer assembly further includes an adjusting rod 305, a buffer damper 311, a buffer spring 310, a rotating shaft 306, a rotating wheel 307, a limiting block 308 and a sliding groove 309; the other end of the mounting shaft 304 is provided with an adjusting rod 305, one end of the adjusting rod 305 is provided with a rotating shaft 306, one end of the rotating shaft 306 is provided with a rotating wheel 307, a sliding groove 309 is formed on the inner wall of the anti-collision frame 2, the rotating wheel 307 is rotatably connected to the sliding groove 309, a limiting block 308 is provided on the side wall of the guide block 202, the side wall of the limiting block 308 is in contact connection with the side wall of the adjusting rod 305, a buffer spring 310 is provided outside the guide rod 201, one end of the buffer spring 310 is fixedly connected to one side of the guide block 202, the other end of the buffer spring 310 is fixedly connected to the inner wall of the guide groove 203, and a buffer damper 311 is provided on the side wall of the guide rod 201;When the anti-collision frame 2 is impacted by the outside world, the impact force first acts on the anti-collision frame 2 and is transmitted to the rotating wheel 307 through the sliding groove 309 on the inner wall of the anti-collision frame 2. After being impacted, the rotating wheel 307 starts to rotate and drives the adjusting rod 305 and the mounting shaft 304 to move together. As the mounting shaft 304 moves, the scroll spring 303 is compressed and deformed, storing the impact energy. The elastic characteristics of the scroll spring 303 can slow down the moving speed of the mounting shaft 304 and the adjusting rod 305, thereby prolonging the acting time of the impact force and reducing the peak impact force. At the same time, the guide rod 201 will also move under the action of the impact force. The buffer spring 310 outside the guide rod 201 is compressed and generates a reaction force, which counteracts the impact force and further slows down the impact of the impact force on the anti-collision frame 2. The buffer damper 311 generates a damping effect on the movement of the guide rod 201 through its viscous or elastic characteristics, further prolonging the acting time of the impact force and reducing the peak impact force. The presence of the limit block 308 ensures that the adjusting rod 305 and the rotating wheel 307 will not exceed the set range during the movement process, thus ensuring the stability and reliability of the buffer assembly. Through the synergistic effect of components such as the scroll spring 303, the buffer spring 310, the buffer damper 311, the rotating wheel 307, the limit block 308, and the guide rod 201, the buffer assembly can effectively weaken the impact of the impact force on the bridge structure and improve the overall protection effect of the anti-collision device. When it returns to the initial position, the presence of the limit block 308 ensures that the adjusting rod 305 and the rotating wheel 307 will not exceed the set range during the movement process, thus ensuring the stability and reliability of the buffer assembly. Through the buffering effect of the scroll spring 303 and the limiting effect of the limit block 308, the buffer assembly can further weaken the impact of the impact force on the bridge structure and improve the overall protection effect of the anti-collision device; The installation assembly includes installation ears 401 and installation threaded holes 402; On the other side of the installation plate 1, there are installation ears 401. There are multiple groups of installation ears 401, and installation threaded holes 402 are opened inside the installation ears 401; It is set on the other side of the installation plate 1, usually in multiple groups, and is used to provide a fixed point for the installation bolt 403. The design of the installation ear 401 needs to ensure that it can withstand the force generated when the anti-collision device is impacted and maintain the stability of the device; The installation assembly also includes an installation bolt 403 and an installation nut 404; An installation bolt 403 is arranged inside the installation threaded hole 402. The installation bolt 403 is threadedly connected to the installation ear 401 through the installation threaded hole 402. One end of the installation bolt 403 is provided with an installation nut 404, and the installation nut 404 is threadedly connected to the installation bolt 403;First, place the mounting plate 1 at the designated mounting position on the bridge and ensure it is stable without shaking. Then, pass the mounting bolt 403 through the mounting threaded hole 402 inside the mounting ear 401, and screw the mounting nut 404 onto the end of the mounting bolt 403. By rotating the nut, a tightening force is generated. During this process, the mounting bolt 403 gradually penetrates along the mounting threaded hole 402 until the predetermined tightening degree is reached. At this time, the mounting plate 1 and the anti-collision device are firmly fixed on the bridge.;

[0027] When the bridge anti-collision device is in use, first, place the mounting plate 1 at the designated mounting position on the bridge and ensure it is stable without shaking. Then, pass the mounting bolt 403 through the mounting threaded hole 402 inside the mounting ear 401, and screw the mounting nut 404 onto the end of the mounting bolt 403. By rotating the nut, a tightening force is generated. During this process, the mounting bolt 403 gradually penetrates along the mounting threaded hole 402 until the predetermined tightening degree is reached. At this time, the mounting plate 1 and the anti-collision device are firmly fixed on the bridge;

[0028] When the anti-collision frame 2 is impacted by the outside world, the impact force is transmitted through the anti-collision frame 2 to the sliding cylinder 4, causing the sliding cylinder 4 to buffer and contract along the fixed cylinder 5. During this process, the impact force is initially dispersed and transmitted to the fixed cylinder 5 and the shock-absorbing components inside it. As the sliding cylinder 4 slides, the sliding block 102 moves along the fixed rod 101;

[0029] During this process, the shock-absorbing damper 103 plays a role. By its viscous or elastic characteristics, it generates damping on the movement of the sliding block 102, slows down the sliding speed, thereby prolonging the action time of the impact force and reducing the peak impact force;

[0030] When the sliding block 102 slides, the connected shock-absorbing spring 104 is compressed, absorbing and storing part of the impact energy. During this process, the elastic deformation of the shock-absorbing spring 104 can effectively slow down the transmission of the impact force and disperse and absorb the impact energy. Although the reset spring 105 does not directly participate in shock absorption during the impact, it plays an important role after the impact. Through its elastic restoring force, the reset spring 105 helps the sliding block 102 and the sliding cylinder 4 return to the initial position to prepare for the next impact;

[0031] When the anti-collision frame 2 is impacted by the outside world, the impact force first acts on the anti-collision frame 2 and is transmitted through the sliding groove 309 on the inner wall of the anti-collision frame 2 to the rotating wheel 307. After being impacted, the rotating wheel 307 starts to rotate and drives the adjusting rod 305 and the mounting shaft 304 to move together. As the mounting shaft 304 moves, the scroll spring 303 is compressed and deformed, storing the impact energy. The elastic characteristics of the scroll spring 303 can slow down the moving speed of the mounting shaft 304 and the adjusting rod 305, thereby prolonging the action time of the impact force and reducing the peak impact force;

[0032] Meanwhile, the guide rod 201 will also move under the action of the impact force. The buffer spring 310 outside the guide rod 201 is compressed and generates a reaction force, which counteracts the impact force and further reduces the impact of the impact force on the anti-collision frame 2. The shock damping 103 exerts a damping effect on the movement of the guide rod 201 through its viscous or elastic characteristics, further prolonging the action time of the impact force and reducing the peak impact force;

[0033] The presence of the limit block 308 ensures that the adjusting rod 305 and the rotating wheel 307 will not exceed the set range during the movement process, thus ensuring the stability and reliability of the buffer assembly;

[0034] Through the coordinated action of components such as the scroll spring 303, the buffer spring 310, the shock damping 103, the rotating wheel 307, the limit block 308, and the guide rod 201, the buffer assembly can effectively weaken the impact of the impact force on the bridge structure and improve the overall protection effect of the anti-collision device.

[0035] Through the above steps, when the bridge anti-collision device is in use, first, the mounting plate 1 is fixedly installed at the designated installation position of the bridge through the mounting assembly. When the anti-collision frame 2 is impacted by an external vehicle or other object, the impact force first acts on the impact surface 3. Due to the sliding connection design of the sliding cylinder 4 and the fixed cylinder 5, the anti-collision frame 2 will drive the sliding cylinder 4 to slide along the fixed cylinder 5. During this process, the impact force is dispersed and transmitted to the fixed cylinder 5 and the mounting plate 1. During the sliding process, the shock absorption assembly and the buffer assembly work simultaneously. The shock absorption assembly slows down the transmission speed of the impact force through its elastic or damping characteristics, while the buffer assembly provides an additional buffering effect to reduce the direct action of the impact force on the bridge structure. Through the sliding of the sliding cylinder 4, the shock absorption of the shock absorption assembly, and the buffering of the buffer assembly, the impact energy is gradually absorbed and dissipated. In this way, it can not only protect the bridge structure from damage, but also reduce the rebound and secondary damage of the vehicle or the impact object, thereby improving the use effect of the device's shock absorption and buffering.

[0036] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
