Articulated link chain, guard rail block and guard rail

Abstract

The invention discloses a hinged chain, a guardrail block and a guardrail by a plurality of embodiments; wherein, the hinged chain is composed of two or more than two hinged elements used for being fixedly installed on the guardrail block and more than one tension member connected on the hinged elements, and the tension member is connected between any two hinged elements. The guardrail block comprises a guardrail body internally provided with more than one hinged elements used for connecting the tension member; one end or both ends of the guardrail body is/are provided with hollow parts, and the hinged part of the hinged element extends to the hollow part. The guardrail is composed of two or more than two guardrail blocks and more than one tension members, and more than one tension members are connected between any two of the guardrail blocks. The guardrail blocks are reasonably hinged and arranged by the hinged chains so as to absorb partial pump energy of accident vehicles without increasing the space of the isolation belt and improve the security of drivers and traffic.

Description

technical field [0001] The invention relates to a hinged chain, especially a hinged chain which is arranged on a guardrail block and can be used to connect several guardrail blocks to each other, so as to prevent guardrails from falling off, overturning, and dislocation due to impact, and to improve the safety of traffic roads and vehicles. safety. The present invention also relates to a guardrail block, especially a hinged chain, which is used to prevent the guardrail from falling off, overturning, and dislocation due to impact, and to improve the safety of traffic roads and vehicles. The present invention further relates to a guardrail, especially a guardrail made of the aforementioned guardrail blocks, which is used to prevent the guardrail from breaking off, overturning, and dislocation due to impact, and to improve the safety of traffic roads and vehicles, and belongs to the technical field of traffic facilities . Background technique [0002] With the acceleration of...

AI Technical Summary

Problems solved by technology

Once the guardrail block 20 is knocked open due to lack of connection, it will enter the opposite lane, and the vehicle in the collision accident will block the original lane, causing the two lanes to and from all to be blocked, causing chain vicious traffic accidents in severe cases Therefore, when the above-mentioned situation occurred, the existing concrete guardrail not only lost the function of blocking the vehicle causing the accident, but the out-of-control vehicle was also likely to block the two traffic lanes at the same time, which could not bring into play the role of traffic protection. bring adverse effects
