Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge traffic safety facilities, in particular to a flexible anti-collision protection device for highway bridge piers. Background Technique

[0002] As is well known, anti-collision bridge piers are very common road and bridge and maritime traffic safety facilities and are widely used in some dangerous areas. When an object such as a hull or a vehicle collides with a bridge pier, setting an anti-collision bridge pier or a bridge pier anti-collision installation kit with buffering performance can greatly buffer the huge impact force generated by the collision, thereby greatly reducing the serious consequences caused by traffic collision accidents. Under the action of the huge impact force, a firm, impact-resistant and well-buffered anti-collision bridge pier is a very necessary road and bridge and maritime traffic safety infrastructure.

[0003] Existing anti-collision protection devices are usually flexible and elastic devices that surround the bridge pier to play an anti-collision protection role for the bridge pier. However, when a collision occurs, as Figure 1 shown, the buffered impact force will still directly act on the bridge pier, and the bridge pier is prone to damage. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a flexible anti-collision protection device for highway bridge piers, which can effectively reduce the force acting on the bridge pier and prevent the bridge pier from being damaged.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A flexible anti-collision protection device for highway bridge piers includes a protection block for protecting the bridge pier. Several support blocks are installed between the protection block and the bridge pier. A number of installation holes are provided in the support blocks. When the support block is impacted, the expansion direction of the installation holes is different from the direction of the impact force. Several elastic components are arranged in each installation hole, and the elastic force direction of the elastic components is the same as the expansion direction of the installation holes.

[0008] Further, the cross-sectional shape of the installation hole is preferably a parallelogram.

[0009] Furthermore, the elastic component is a rubber column.

[0010] Furthermore, the elastic component is a spring.

[0011] In addition, the protection block is made of a flexible and elastic material.

[0012] In addition, the support block is made of a flexible and elastic material.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the utility model provides a flexible anti-collision protection device for highway bridge piers, which has the following beneficial effects:

[0015] For the flexible anti-collision protection device for highway bridge piers, through the arrangement of the mounting holes and the elastic components, when a collision occurs, the expansion direction of the mounting holes is different from the direction of the impact force. The direction of a part of the impact force is converted to other directions by the mounting holes, and the mounting holes expand to stretch the elastic components. The elastic components consume a large amount of impact energy, thereby effectively reducing the force acting on the bridge pier during the collision and preventing the bridge pier from being damaged, providing better protection for the bridge pier.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 , a flexible anti-collision protection device for highway bridge piers of the present utility model includes a protection block 1 for protecting the bridge pier 2, and several support blocks 3 are installed between the protection block 1 and the bridge pier 2.

[0025] A number of mounting holes 4 are provided inside the support block 3. When the support block 3 is impacted, the expansion direction of the mounting holes 4 is different from the direction of the impact force. The cross-sectional shape of the mounting holes 4 is preferably a parallelogram. For example, when the impact force is horizontal, the mounting holes 4 can convert part of the impact force into a vertical direction to reduce the force acting on the bridge pier 2.

[0026] A number of elastic components are provided in each mounting hole 4. The elastic force direction of the elastic components is the same as the expansion direction of the mounting holes 4. The elastic components consume the impact energy to further reduce the force acting on the bridge pier 2.

[0027] Among them, the elastic component is a rubber column 5. During the stretching process of the rubber column 5, it can also directly consume the impact energy by itself.

[0028] Among them, the elastic component is a spring 6, and the elastic effect of the spring is better.

[0029] Among them, the protective block 1 is made of a flexible and elastic material.

[0030] Among them, the support block 3 is made of a flexible and elastic material.

[0031] In summary, for this flexible anti-collision protection device for highway bridge piers, during use, when an impact occurs, the expansion direction of the mounting holes 4 is different from the direction of the impact force. The direction of part of the impact force is converted by the mounting holes 4 to other directions. For example, when the impact force is horizontal, the mounting holes 4 can convert part of the impact force into a vertical direction, and the expansion of the mounting holes 4 stretches the elastic force components, and the elastic force components consume a large amount of impact energy, effectively reducing the force acting on the bridge pier 2 during impact.
