Anti-collision device for waterway bridge
The invention discloses an anti-collision device for a waterway bridge. The anti-collision device comprises a front anti-collision trunk, a side anti-collision trunk, a guide rail buffer unit, a connecting piece and a warning device. The anti-collision device is mainly characterized in that collision energy is absorbed by using plastic deformation of a honeycomb core and side plates at the periphery of the honeycomb core; when a ship collides with the bridge, the anti-collision trunks generate greater plastic deformation under the action of an impact load, so that the collision energy is absorbed; the warning device is connected to corresponding switches inside the front anti-collision trunk and the side anti-collision trunk, and gives out corresponding sound and light signals for maintenance personnel to timely check damage conditions after accidents and replace corresponding parts. Compared with a steel structure anti-collision cofferdam, the anti-collision device disclosed by the invention has the advantages that the resistance borne by the anti-collision trunks during up-down floating is reduced by the guide rail buffer unit; the anti-collision device has a guiding action, and is higher in wear resistance, adjustable in protection capability, low in production and maintenance cost and convenient to connect.
