Description

Technical Field

[0001] This utility model relates to the field of roads and bridges, and in particular to a road and bridge anti-collision device. Background Technology

[0002] An existing patent (publication number: CN218029467U) discloses an anti-collision device for road and bridge engineering, including a base. A first mounting groove is formed on the front of the base, a spring shock absorber is installed at the bottom inside the first mounting groove, and a buffer pad is installed at the top inside the first mounting groove. A protective plate extending to the outside of the base is installed on the front of the buffer pad. A second mounting groove extending inwards from the top of the base is formed, and a sound insulation plate is slidably installed inside the second mounting groove. A sliding track is formed on the back of the base. However, the "protective plate" mounting structure in this device is relatively fixed, making it difficult to quickly replace after damage from an impact, reducing the efficiency of device maintenance and presenting a drawback. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a road and bridge anti-collision device that serves as a warning while mitigating and absorbing the impact force generated during a collision, reducing damage to the bridge structure, lowering the risk of injury to vehicles and occupants, and facilitating easy disassembly and replacement of the anti-collision plate, thereby improving the efficiency of device maintenance.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A road and bridge anti-collision device includes a guardrail, rubber anti-collision blocks, anti-collision plates, support plates, limiting plates, movable plates, and positioning rods. The guardrail is connected to reflective warning strips and has multiple fixed uprights. Each fixed upright has a central through hole in its middle and fixed horizontal plates on both sides. Each fixed horizontal plate has multiple sliding tracks that are adapted to the support plates. The support plates are connected to the sliding tracks and slide within the tracks. One end of a secondary spring is connected to the support plate, and the other end of the secondary spring is connected to the fixed horizontal plate. A limiting plate is connected to the outside of the fixed horizontal plate. The limiting plate has multiple locking blocks, and the fixed horizontal plate has multiple locking block through holes. The support plate has locking grooves that are adapted to the locking blocks. The locking blocks pass through the locking block through holes and are connected to the locking grooves.

[0006] The support plate of this utility model has a positioning rod through hole, and the anti-collision plate has a positioning groove. The positioning groove and the positioning rod through hole are adapted to the positioning rod. The positioning rod passes through the positioning rod through hole. The inner end of the positioning rod is connected to the positioning groove by a thread. The outer end of the positioning rod has a knob. The knob fits against the outer side of the support plate. The inner side of the support plate is connected to the anti-collision plate. The outer side of the anti-collision plate has a rubber anti-collision block. The inner side of the anti-collision plate has a central rod.

[0007] The central rod of this utility model is adapted to the central through hole. The central rod passes through the main spring strip, the movable plate and the central through hole in sequence. The outer side of the movable plate is attached to the fixed upright, the inner side of the movable plate is connected to the main spring strip, and the main spring strip is connected to the anti-collision plate. Beneficial effects

[0008] This utility model of guardrail protects roads and bridges by enclosing them, preventing out-of-control vehicles from directly impacting the bridge structure and increasing the protection of roads and bridges. At the same time, by adding reflective warning strips, the guardrail enhances its visibility and visual warning effect. It also reflects the surrounding light sources at night or in low-light environments, allowing drivers to notice the guardrail ahead in advance and maintain a safe distance from it.

[0009] This utility model of rubber anti-collision block utilizes the high elasticity and high strength properties of rubber, which can quickly deform and absorb impact force when impacted, thereby reducing the direct impact on the bridge structure and protecting the bridge from damage. At the same time, the rubber anti-collision block has good weather resistance and corrosion resistance, and can maintain stable performance under extreme weather conditions, ensuring long-term stable use. It also has a reasonable structure.

[0010] When the rubber anti-collision block is impacted, the main spring strip, secondary spring, outer connecting rod, and inner connecting rod are simultaneously compressed to alleviate the impact force generated during the collision. The rubber anti-collision block absorbs the collision energy, reducing damage to the bridge structure and minimizing injury to vehicles and occupants. Furthermore, the anti-collision plate is fixedly connected to the support plate via a positioning rod, making disassembly convenient and facilitating quick replacement of damaged anti-collision plates after a collision. This improves the efficiency of device maintenance while ensuring its buffering effect.

[0011] This utility model provides a protective barrier for roads and bridges, serving as a warning while mitigating and absorbing the impact force generated during a collision, reducing damage to the bridge structure, and minimizing injuries to vehicles and occupants. Furthermore, the anti-collision plate is easy to disassemble and replace, improving the efficiency of device maintenance. Attached Figure Description
