Technical Field

[0001] The utility model relates to the technical field of bridge protection, in particular to a bridge anti-collision device. Background Art

[0002] Bridges, as a road connecting structure, are very common in daily life. Usually, bridges are composed of foundations, piers and spans. In some areas with dense road networks, or in order to meet the requirements of road lines, piers will appear on the road below the span. Since the piers are the supporting structure of the span, when the structure of the piers is disturbed, it will affect the stability of the span structure.

[0003] A bridge anti-collision device with a search announcement number of CN 214882945 U is disclosed, comprising a plurality of anti-collision devices arranged in a straight line along the direction of travel of a road, each anti-collision device comprising a vertical barrel that can rotate around its own axis and can be reset, the middle portion of the barrel being provided with an elastic barrel, the upper and lower side surfaces of the elastic barrel being provided with rigid surfaces, a sleeve being provided on the outer surface of the barrel that can move horizontally on a horizontal plane, a gap being provided between the sleeve and the barrel, a plurality of damping rods being uniformly distributed on the circumference of the sleeve along the radial direction of the sleeve, the plurality of circumferentially uniformly distributed damping rods being uniformly distributed in multiple layers along the upper and lower directions of the sleeve, the inner end of the damping rod being located in the gap between the sleeve and the barrel and the inner end of the damping rod being connected to the elastic barrel, the damping rod being able to move radially inward and outward along the sleeve and causing the elastic barrel to deform; the utility model has a novel concept, an ingenious structure and strong practicality.

[0004] However, the above device still has some shortcomings during use. It can only protect against collision on one side and cannot unload force, resulting in poor protection effect. At the same time, the components are easily damaged after being hit, and individual components cannot be quickly installed and disassembled, making it inconvenient to replace. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a bridge anti-collision device, which solves the problems of only being able to prevent collision on one side, being unable to unload force, having poor protection effect, and easily damaged components after being impacted, being unable to quickly install and disassemble individual components, and being inconvenient to replace.

[0006] The present utility model provides the following technical solution: a bridge anti-collision device, including a first mounting plate. The number of the first mounting plates is two and they match the size of the bridge piers. Multiple groups of damping rods are fixedly connected to the surfaces of both of the two first mounting plates. One end of each group of damping rods is fixedly connected to an anti-collision plate. Mounting rings are fixedly connected to the top and bottom ends of both of the two first mounting plates. A plurality of limiting rods are fixedly connected between the corresponding two mounting rings. Two limiting sleeves are slidably sleeved on the surface of each limiting rod. A connecting rod is movably connected between each limiting sleeve and the adjacent anti-collision plate. A spring is fixedly sleeved between the two limiting sleeves located on the same limiting rod. A group of anti-collision rollers are arranged on each anti-collision plate.

[0007] Preferred technical solution one: A group of fixing plates are fixedly connected to the upper and lower surfaces of both of the two first mounting plates. Mounting holes are formed on the surfaces of each fixing plate.

[0008] This solution can facilitate the quick installation of the first mounting plate on the bridge piers, making the installation convenient and easy to use.

[0009] Preferred technical solution two: The interior of the first mounting plate is hollow and is provided with a corrugated energy dissipation steel plate. Rubber pads are provided on the outer surface and the inner wall of the first mounting plate.

[0010] This solution can further buffer the collision, protect the bridge piers, and avoid damage.

[0011] Preferred technical solution three: Rotating rods are rotatably connected to the top and bottom ends of each anti-collision roller. A group of second mounting plates are fixedly connected to the top and bottom ends of each anti-collision plate. Empty slots are formed on the surfaces of each second mounting plate. The empty slots match the rotating rods. Threaded holes are formed on the surfaces of each rotating rod and each second mounting plate. Bolts are threadedly sleeved in the threaded holes formed on each rotating rod and the corresponding second mounting plate.

[0012] This solution can facilitate the installation and disassembly of each anti-collision roller, and facilitate its quick replacement.

[0013] Preferred technical solution four: The material of each anti-collision roller is rubber, and a reflective sticker is pasted on the surface of each anti-collision roller.

[0014] This solution can make the rubber material have a protective effect, and at the same time remind ships to avoid by the reflective sticker.

[0015] Preferred technical solution five: Protective coatings are sprayed on the surfaces of the first mounting plate, the anti-collision plate and each component.

[0016] This solution can protect each component against corrosion and rust.

[0017] Compared with the prior art, the utility model provides a bridge anti-collision device, which has the following beneficial effects: When in use, the two mounting plates one are fixedly installed on the outer circle of the bridge pier through the fixing plate and the mounting holes. When a ship collides with the bridge pier, it will first hit the anti-collision roller, driving the anti-collision roller to rotate. The rotation of the anti-collision roller will change the direction of the ship collision force and guide the yawing ship to turn and slide away along the outside of the anti-collision roller, taking away most of the kinetic energy of the ship and greatly reducing the impact destructive force of the ship. At the same time, when being hit head-on, the anti-collision roller and the anti-collision plate will move inward. The connecting rod, the limiting sleeve, the spring and the damping rod are used in combination to buffer the force generated by the collision and avoid damage to the bridge pier. At the same time, the force exerted on the rubber pad on the mounting plate one by the damping rod will be absorbed and consumed by the corrugated energy-consuming steel plate, further protecting the bridge pier. At the same time, each anti-collision roller can be quickly installed and disassembled through bolts and rotating rods, which is convenient for replacement. When the device is in use, the bridge can be protected in various ways to avoid damage caused by collision, and at the same time, it is convenient to quickly install and disassemble the anti-collision roller for replacement.
