The invention relates to a bridge pier anti-collision device. The device effectively solves the problems that buffering equipment is poor in adaptability, the upper limit of buffering force is small, and larger residual impact force transversely acts on a bridge pier. According to the technical scheme, the bridge pier anti-collision device comprises an upper buffering unit and a lower buffering unit, the upper buffering unit absorbs energy through an elastic piece and is used for buffering impact with smaller impact force, the lower buffering unit is arranged below the water surface and comprises an outer sleeve and an inner sleeve, and an upper gear, a lower gear, an upper circular plate and a lower circular plate are installed outside the inner sleeve; the two circular plates are in threaded connection with the inner sleeve, gaps are formed between the two circular plates and the inner wall of the outer sleeve, the upper circular plate synchronously rotates along with the upper gear, the lower circular plate synchronously rotates along with the lower gear, each gear is meshed with a gear rack, and during large-force impact, the gear racks push the gears to rotate, and the two circular plates axially move to drain water to form buffer resistance; and the device is high in adaptability to impact force, the upper limit of buffering force is large, and a bridge pier is not subjected to transverse counter-acting force.
本发明涉及一种桥墩防撞装置，有效的解决了缓冲设备适应力差，缓冲力上限小，会有较大残余撞击力横向作用于桥墩上的问题；解决的技术方案包括上部缓冲单元和下部缓冲单元，上部缓冲单元通过弹性件吸能，用于缓冲冲击力较小的撞击，下部缓冲单元置于水面以下，包括外套筒和内套筒，内套筒外安装有上齿轮、下齿轮、上圆板、下圆板，两圆板均与内套筒之间螺纹连接，且两圆板与外套筒内壁之间均有缝隙，上圆板随上齿轮同步转动，下圆板随下齿轮同步转动，每个齿轮均啮合有一个齿条，大力度撞击时，齿条推动齿轮转动，两个圆板轴向移动排水形成缓冲阻力；本发明对撞击力度的适应性强，缓冲力上限大，桥墩不受横向反作用力。
