Abstract

The invention relates to a height-limiting and anti-collision device for a bridge frame. The height-limiting and anti-collision device for the bridge frame is characterized in that a plurality of anti-collision mechanisms consisting of buffers 3 and collided members 4 are arranged on the outer side of the bridge frame 1 of a bridge, an anti-collision frame 2, a pedestrian branch bridge frame 6 and a bridge frame 71 of a pedestrian branch bridge 7; the anti-collision mechanisms are connected by arresting members 5 or arresting devices 5 to form the height-limiting and anti-collision device for the bridge frame. The beneficial effects of the height-limiting and anti-collision device for the bridge frame are that the collided members and the arresting members of the height-limiting and anti-collision device are arranged on the outer side of the bridge and the outer side of the bridge frame, the anti-collision frame, a pedestrian branch bridge frame, or the bridge frame of the pedestrian branch bridge, if a ship or a car collides with the collided members and the arresting members of the height-limiting and anti-collision device, the arresting members and the collided members are in a linkage so that the impact forces of the ship collision or the car collision tend to be balanced, the buffers are compressed to work by the collided members, the kinetic energy of an accident ship or an accident car is consumed, the speed of the ship or the car is reduced, and the ship or the car stops. The device effectively solves the purpose of protecting the ship collision and the car collision of the bridge frame.

Description

technical field

[0001] The invention relates to the anti-collision technology of the bridge bridge frame, which is mainly used for the anti-collision device of the bridge frame caused by ship collision and vehicle collision, and is used to protect the bridge frame in the anti-collision device to avoid damage caused by the collision of ships and vehicles. Background technique

[0002] At present, most of the bridge frames in rivers, lakes and seas are arc-shaped bridge frames. When a ship passes the bridge hole, the top of the ship is higher than the height of the bridge and collides with the bridge frame. The collision bridge frame is affected by the following factors: Uncertainty of tide ;Changes in tides; changes in water flow; changes in waterways; Side impact, side impact, and deflection impact, so the bridge frame of the bridge must be equipped with a height limit anti-collision device to protect the safety of the bridge.

[0003] At present, car girder anti-collision ...
