Deformation-recoverable anti-collision device for main cable of suspension bridge
The invention discloses a deformation-recoverable suspension bridge main cable anti-collision device which is embraced on a main cable in a pile casing form within a collapsing stone collision range, specifically, a hoop is embraced on the main cable and is fixed through an M12 bolt, the hoop is welded with an inner connecting plate of a plurality of composite hyperelastic buffer bodies, and the composite hyperelastic buffer bodies are connected with the pile casing. The outer connecting plate of the composite hyperelastic buffer body is fixed with the casing shell through an M12 bolt, and the casing shell is secondarily connected through a flange; the composite hyperelastic buffer body is made into an arc-shaped inner connecting plate and an arc-shaped outer connecting plate by two square steel plates, and a cylindrical composite elastic buffer column is poured between the inner connecting plate and the outer connecting plate. The device has the characteristics of high energy absorption rate, recoverable deformation, low-energy repeated use, recoverable local deformation, low maintenance cost and the like.
本发明公开了一种变形可恢复的悬索桥主缆防撞装置，在崩石撞击范围内，以护筒形式合抱于主缆上，具体为：抱箍合抱于主缆上，并通过M12螺栓固定，抱箍与若干复合超弹性缓冲体的内连接板焊接，复合超弹性缓冲体的外连接板和护筒外壳通过M12螺栓固定，将护筒外壳通过法兰进行二次连接；复合超弹性缓冲体由两块方形钢板制作成弧形的内连接板和外连接板，在内连接板和外连接板之间浇筑圆柱形复合弹性缓冲柱。本发明具有能量吸收率高、变形可恢复、低能量反复使用、局部变形可恢复，维护成本低等特点。
