Bridge height limiting anti-collision device

Abstract

The embodiment of the invention discloses a bridge height limiting anti-collision device. According to the technical scheme, the height limiting steel pipe is transversely arranged along the outer side of the lower edge of the bridge, the first end of the screw rod is fixedly connected with the bridge, and the other end of the screw rod axially penetrates through the spring and the height limitingsteel pipe in the radial direction and is fixedly locked through the nut so as to fix the height limiting steel pipe. By the adoption of the technical means, the good impact buffering effect can be achieved through the height limiting steel pipes and the springs, the anti-collision structure arrangement is simplified while the anti-collision effect of a bridge is guaranteed, the arrangement difficulty and maintenance difficulty of anti-collision measures are reduced, and the arrangement cost and maintenance cost of the anti-collision measures are reduced. Besides, the pressure information ofthe buffer fixing structure is collected by arranging a sensor and uploaded to a system background, real-time alarming and positioning of bridge collision are achieved, and the bridge management effect is optimized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of bridge engineering, in particular to a bridge height limit and anti-collision device. Background technique [0002] With the development of society and economy, the size, volume, load and quantity of vehicles and ships are gradually increasing, while the existing bridges spanning rivers or highways are generally small in bridge span and height in the early design, and the traffic under the bridge The headroom standard is relatively low, resulting in frequent accidents hitting the upper span bridges, easily causing damage to boats or vehicles, casualties, and even traffic interruptions. [0003] In order to avoid the risk of collision with large bridges, special anti-collision facilities are usually installed on the piers, and a special early warning system is further configured to provide good early warning and damage reduction effects. However, for small and medium-sized brid...
