Bridge anti-collision cable
The invention provides a bridge anti-collision cable. A bridge and a riverway are included. The anti-collision cable is arranged on one or two sides of the bridge and comprises two stand columns. Thetop end of each stand column is provided with a pulley. The two stand columns are connected through a steel cable. The steel cable is provided with a tightening and loosening spring. The steel cable stretches across the two sides of the riverway, bypasses the pulleys and is connected with a braking device. The steel cable penetrates through the braking device and is connected with a gravity block.The steel cable installing height is equal to the free height of a bridge navigation hole. The width between the two stand columns is equal to the free height of the bridge navigation hole. The device is provided with the braking device, the braking device can be utilized for preventing the steel cable from being continuously stretched, and the function of braking deceleration is achieved. Meanwhile, the gravity block is arranged to prevent a ship from colliding with the bridge, through traction of the gravity block, the ship towing action is enhanced, an ultra-high ship is further preventedfrom colliding with the bridge, and the characteristics that the structure is simple, installation is convenient, and achieving is easy are achieved.
本发明提供一种桥梁防撞索，包括桥梁和河道，桥梁的一侧或两侧设置有防撞索，防撞索包括两个立柱，每个立柱顶端设置有滑轮，两个立柱通过钢索连接，钢索上设置有松紧弹簧，钢索横跨河道两侧且绕过滑轮接入制动装置，钢索穿过制动装置与重力块连接，钢索的安装高度与桥梁通航孔的净空高度相等，两个立柱之间的宽度与桥梁通航孔的净空宽度相等。本装置上安装有制动装置，可利用制动装置阻止钢索继续被拉伸，起到制动减速的作用，同时，装有重力块，来阻止船只撞向桥梁，利用重力块的牵引，增大对船只进行的拖航作用，进一步防止超高船舶撞向桥梁，具有结构简单，安装方便，易于实现的特点。
