The invention relates to a bridge guardrail capable of changing the impact direction of a vehicle. The problems that an existing guardrail cannot conduct buffering, vehicle intervention cannot be conducted, and secondary injury to personnel is likely to be caused are solved. Larger safety accidents caused by the fact that the vehicle rushes out of the bridge floor are avoided; the bridge guardrailcomprises a base body, a cross beam arranged above the base body and a plurality of vertical rods used for supporting the cross beam. An arc-shaped sliding groove facing the inner side of a bridge isformed in the base body, a sliding block is arranged in the arc-shaped sliding groove, an anti-collision rod vertically arranged above the sliding block is arranged on the sliding block, an arc-shaped guide groove is formed in the cross beam, the arc-shaped sliding groove corresponds to the arc-shaped guide groove in an up-down mode, and the radian of the arc-shaped sliding groove is consistent with that of the arc-shaped guide groove. The upper end of the anti-collision rod is arranged in the arc-shaped guide groove in a sliding mode. A pushing sliding block which slides vertically is arranged on the vertical rod, the pushing sliding block and the sliding block are universally hinged through a connecting rod, and the connecting rod is obliquely arranged towards the outer side of the cross beam; the bridge guardrail further comprises a gravity beam arranged above the cross beam, a plurality of vertical ejector rods arranged below the gravity beam are arranged on the gravity beam, andthe lower ends of the vertical ejector rods slide downwards to penetrate through the cross beam and make contact with the pushing sliding block.
本发明涉及一种改变车辆撞击方向的桥梁护栏，以解决现有护栏无法进行缓冲、对无法进行车辆干预和易造成人员次生伤害的问题，避免车辆冲出桥面而引发更大的安全事故，包括基体、置于基体上方的横梁和用于支撑横梁的多个竖杆，基体上有朝向桥梁内侧方向的弧形滑槽，弧形滑槽内有滑块，滑块上有置于滑块上方竖向设置的防撞杆，横梁上有弧形导槽，弧形滑槽与弧形导槽上下对应且弧度一致，防撞杆的上端滑动置于弧形导槽内；竖杆上有竖向滑动的顶推滑块，顶推滑块与滑块之间经连杆万向铰接，连杆向横梁外侧方向倾斜设置；还包括置于横梁上方的重力梁，重力梁上有置于重力梁下方的多个竖直顶杆，竖直顶杆的下端向下滑动贯穿横梁并与顶推滑块接触。
