Description

Technical Field

[0001] The utility model belongs to the technical field of anti-collision protection for municipal bridges, and in particular relates to an anti-collision protection device for municipal bridges. Background Art

[0002] The anti-collision protection device for municipal bridges is a protective facility installed on both sides of the bridge that uses the principles of momentum conservation and energy absorption to reduce or avoid accidents caused by vehicles hitting the bridge. It mainly plays a role of buffering and absorbing energy when a traffic accident occurs. The anti-collision protection device for municipal bridges can not only prevent vehicles from hitting the bridge, but also improve the durability of the bridge. It is widely used on bridges such as highways, railways, and urban roads, especially in places with large bridge slopes, safety hazards, heavy traffic, large vehicle flow or high driving speed, and places with high traffic safety requirements.

[0003] Chinese patent announcement number CN214695342U relates to the technical field of bridge protection, and discloses a municipal bridge protection device, including a protection column, the bottom end of the protection column is fixedly connected to a base, and the left outer wall of the base is fixedly connected to a connecting plate. The municipal bridge protection device can quickly install the protection net through the cooperation of the second mounting ring, the mounting block and the positioning pin, reduce the labor of the workers, and improve the installation efficiency of the protection device. The stability of the protection device is improved by the ground cone, the clamping column is driven to move forward through the pull ring, and the clamping column compresses the compression spring through the fixed block to make the clamping column detach from the protection column, and the fixed concave block is driven to move up and down by the moving clamping block, and the pull ring is adjusted to a suitable height to release the pull ring, and the clamping column is driven to fix the lifting block through the reaction force of the compression spring, and the protection nets of different heights can be installed, which improves the practicality of the protection device.
