Emergency anti-collision device for highway engineering

Abstract

The invention discloses an emergency anti-collision device for highway engineering, and belongs to the technical field of anti-collision guardrails. According to the emergency anti-collision device for highway engineering, an annular cutter is arranged on a base, and an anti-collision rod is arranged in the annular cutter so that the anti-collision rod can be timely cut off by the annular cutter when being directly collided by a vehicle; prevention of a secondary traffic accident caused by vehicle rebounding back to the lane is achieved; when the out-of-control vehicle collides with the anti-collision baffles, the anti-collision panels between the adjacent anti-collision rods are collided, the energy absorption cylinders are extruded to collapse inwards to absorb kinetic energy of the vehicle, in addition, the buffer cables are stretched by an impact force and drive the sliding blocks to slide in the limiting sliding grooves, and the kinetic energy of the vehicle is absorbed; and when the collision force of the vehicle is too large, the anti-collision baffles and the buffer cables pull the anti-collision rods to be bent and cut off by the annular cutter, at the moment, the multiple sections of anti-collision baffles and the buffer cables in the anti-collision baffles are stressed at the same time, and the vehicle is buffered.

Description

technical field [0001] The invention relates to the technical field of anti-collision guardrails, and more specifically relates to an emergency anti-collision device for highway engineering. Background technique [0002] The highway anti-collision guardrail is the most important traffic infrastructure. The expressway in our country was developed in the 1980s. It plays an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility for the expressway. It can be used as a permanent fence net wall or as a temporary isolation net. It can be realized by using different column fixing methods in use. [0003] At present, the protection capacity of domestic anti-collision barriers is limited, and they cannot effectively absorb the kinetic energy of out-of-control vehicles when encountering severe impacts, resulting in serious damage to the vehicles and threats to the lives of internal personnel. In addition, when...

[0003] At present, the protection capacity of domestic anti-collision barriers is limited, and they cannot effectively absorb the kinetic energy of out-of-control vehicles when encountering severe impacts, resulting in serious damage to the vehicles and threats to the lives of internal personnel. In addition, when the vehicles directly hit the pillars, due to the short buffer distance It will cause more serious injuries to the people in the car, and it is easy for the car to be bounced back to the lane, resulting in a secondary traffic accident
