Description

Technical Field

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

[0002] Bridge guardrails refer to the guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge and beautifying the bridge structure.

[0003] Existing guardrails are generally made of stone, cement and other materials that are carved or poured and solidified. However, these guardrails cause great damage to accident vehicles and do not assist in slowing down vehicles or buffering the impact force of vehicles, thereby increasing the danger to drivers. Although some guardrails with anti-collision functions have appeared on the market, they can only buffer the impact force of vehicles in one direction and have poor anti-collision effects.

[0004] Prior art CN214656356U A road bridge safety anti-collision guardrail realizes a horizontal buffer connection through an anti-collision buffer mechanism and two guardrail crossbeams at the upper and lower ends of the anti-collision column, and through multiple elastic buffers between the buffer outer ring sleeve and the buffer inner ring sleeve. Since multiple elastic buffers are radially annularly arranged between the buffer inner ring sleeve and the buffer outer ring sleeve, when the anti-collision column is hit in different directions horizontally, the impact force can be buffered, so that the vehicle impact force can be buffered in multiple directions, thereby solving the above technical problems. However, the device is an integrated structure. When one or more anti-collision rollers are damaged, they cannot be replaced separately and need to be replaced as a whole, which increases the cost; therefore, it does not meet the existing needs. In this regard, we propose a bridge safety anti-collision mechanism. Utility Model Content
