Energy-absorbing anti-collision mechanism and road guardrail
The invention relates to the technical field of road guardrails, in particular to an energy-absorbing anti-collision mechanism and a road guardrail, the energy-absorbing anti-collision mechanism comprises a protective plate arranged on one side of the protective guardrail, and a rubber strip is arranged on the outer surface of the protective plate; the connecting block is arranged between the protective fence and the protective plate, and a sliding block is arranged in the connecting block; the first storage roller is arranged at the end of the protective fence, and a steel wire rope is arranged on the surface of the first storage roller; the protective fence has the beneficial effects that the rubber strip and the bonding layer can effectively reduce the collision strength, in the collision process, the sliding block compresses the reset spring, meanwhile, the side wall of the sliding block rubs the damping pad, and the first clamping ball and the second clamping ball rub against each other, the collision strength can be reduced, when the protective fence is collided, the protective fence inclines towards one side, the steel wire rope is lengthened, and the safety of the protective fence is improved. The steel wire rope drives the first storage roller to rotate, the first storage roller drives the second storage roller to rotate, the second storage roller stretches the tension spring through the connecting rope in the rotating process, and the tension spring reversely eliminates the impact force due to the elastic force of the tension spring.
本发明涉及公路护栏技术领域，具体为一种吸能防撞机构及公路护栏，包括：防护板，设置在防护栏的一侧，防护板的外表面设置有橡胶条；连接块，设置在防护栏和防护板之间，连接块的内部设置有滑块；第一收纳辊，设置在防护栏的端部，第一收纳辊的表面设置有钢丝绳；有益效果为：橡胶条和粘合层，可以有效减小碰撞的力度，且碰撞过程中，滑块将会压缩复位弹簧，同时滑块的侧壁摩擦阻尼垫，第一卡球与第二卡球相互摩擦，均可减小撞击力度，当防护栏被撞击时，防护栏会向一侧倾斜，钢丝绳会被拉长，钢丝绳带动第一收纳辊进行转动，第一收纳辊带动第二收纳辊进行转动，第二收纳辊转动过程中通过连接绳拉伸拉簧，拉簧由于自身的弹力，反向消除撞击力。
