The invention relates to a bridge pier protection device. The device effectively solves the problems that buffering equipment is poor in adaptability and small in buffering force upper limit, and impact force transversely acts on a bridge pier. According to the technical scheme, the protection device comprises an upper buffering unit and a lower buffering unit, the upper buffering unit absorbs energy through an elastic piece, the lower buffering unit comprises an outer sleeve and an inner sleeve, an upper bevel gear, a lower bevel gear, an upper circular plate and a lower circular plate are installed on the outer wall of the inner sleeve, and the two circular plates are both in threaded connection with the inner sleeve; and a first middle bevel gear and a first straight gear are installed at the right side of the inner sleeve, a second middle bevel gear and a second straight gear are installed at the left side of the inner sleeve, one-way transmission mechanisms are arranged between the straight gears and the middle bevel gears, each straight gear is meshed with a gear rack, and no matter which section of each gear rack is pushed, the upper bevel gear and the lower bevel gear can be driven to rotate in one direction. Therefore, the two circular plates are pulled to axially extrude water to form buffer resistance; and the device is high in adaptability, the upper limit of buffering force is large, and the bridge pier is not subjected to transverse counter-acting force.
本发明涉及一种桥墩保护装置，有效的解决了缓冲设备适应力差，缓冲力上限小，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，下部缓冲单元包括外套筒和内套筒，内套筒外壁上安装有上锥齿轮、下锥齿轮、上圆板、下圆板，两圆板均与内套筒之间螺纹连接，内套筒右侧安装有第一中间锥齿轮和第一直齿轮，左侧安装有第二中间锥齿轮和第二直齿轮，直齿轮与中间锥齿轮之间均设有单向传动机构，每个直齿轮啮合有一个齿条，无论从哪一段推动齿条，都会带动上锥齿轮和下锥齿轮单向转动，从而拉动两个圆板轴向挤压水形成缓冲阻力；本发明的适应性强，缓冲力上限大，桥墩不受横向反作用力。
