The invention discloses a wharf anti-impact fender, and relates to the technical field of fenders, the wharf anti-impact fender comprises a fender fixing plate, one side of the fender fixing plate is fixedly connected with two strong spring seats, one end of each strong spring seat is fixedly connected with a third guide column, and the other end of each strong spring seat is fixedly connected with a second guide column. A strong spring and a limiting column are installed on one side of a fender fixing plate to carry out overload protection on the strong spring, when a ship is in shore, after the ship is buffered through a first-stage fender, the second-stage fender is utilized to continue to consume impact energy, the first-stage fender and the second-stage fender are matched to absorb collision and impact energy together, and therefore the ship is protected against collision and impact. The impact action time is prolonged, and the impact force is reduced, so that the impact of the ship to the wharf is reduced, and the damage to the ship and the wharf is greatly reduced; by the adoption of the compressed air bag, the buffering capacity of the first-stage fender is relatively enhanced, the stability of the first-stage fender is enhanced through the iron chains on the two sides of the first-stage fender, and inclination of the first-stage fender is effectively prevented.

本发明公开了一种码头抗冲击护舷，涉及护舷技术领域，包括护舷固定板，所述护舷固定板的一侧固定连接有两个强力弹簧座，两个所述强力弹簧座的一端均固定连接有第三导向柱，本发明通过采用在护舷固定板的一侧安装强力弹簧以及限位柱对强力弹簧进行的过载保护，当船舶靠岸时，在通过一级护舷缓冲后，顺势利用二级护舷继续对冲击能量进行消耗，配合一级护舷和二级护舷一起吸收碰撞和冲击的能量，增加冲击的作用时间，降低了冲击力，从而降低了船舶对码头的冲击，极大降低了对船舶和码头的损伤；通过采用压缩气囊，相对增强了一级护舷的缓冲能力，且一级护舷两侧的铁链，增强了一级护舷的稳定性，有效防止了一级护舷的倾斜。
