Anti-collision baffle for highway safety

Abstract

The anti-collision baffle for highway safety comprises a fixed plate, a transmission mechanism is fixedly connected to the back face of the fixed plate, limiting mechanisms are movably connected to the top and the bottom of the fixed plate, and a triggering mechanism is movably connected to the left side of the fixed plate. The invention relates to the field of highway protection infrastructures.According to the anti-collision baffle for highway safety, the attaching effect between the curved plate and a touched object in the collision process is achieved through cooperation of the triggeringmechanism and the transmission mechanism; the buffering contact area during collision is increased; the buffering effect on the collision process is realized through the air reed pipe; the impact force per unit area is smaller, the damage degree to a collision object is smaller, the limiting effect on the extrusion plate is achieved through the limiting mechanism, the spring is promoted to compress and accumulate elastic potential energy, more reaction force can be provided to counteract the collision force when collision triggering is carried out, and damage caused by collision is reduced. Therefore, the problem that the buffering and protecting effects of the anti-collision baffle are not ideal is solved.

Description

technical field [0001] The invention relates to the field of road protection infrastructure, in particular to an anti-collision baffle for road safety. Background technique [0002] Fences can play a good guiding role for drivers in urban road planning. At the same time, fencing can also play a role in diverting road traffic vehicles. However, vehicles will inevitably collide with the fencing during driving. Accident road sections often need to install anti-collision baffles in front of the guardrails to enhance driving safety. [0003] The existing patent (notification number: CN108944756A) discloses a car anti-collision steel beam, which includes two fixed blocks. A draw-in groove is provided on the opposite surfaces of the draw-in slots, and a rear baffle is installed in the draw-in groove, and an installation cavity is provided on the upper end surface of the rear baffle. In the process of realizing the present invention, the inventors have found that at least the foll...
