Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision facilities, in particular to an anti-collision facility with buffer energy absorption. Background Art
[0002] Accidents of vehicles or ships hitting bridge piers occur frequently, seriously threatening the safety of bridge structures, vehicles and personnel. Setting up anti-collision structures can achieve the dual effects of reducing the damage of vehicles (ships) and bridges. The traditional bridge anti-collision structures are mainly steel casing boxes, which use the plastic deformation of box-shaped steel structures to play an energy-consuming role. However, such anti-collision structures have problems such as large size, large stiffness, and low energy-consuming efficiency, and it is difficult to ensure the damage degrees of both the bridge piers and the ships (vehicles) at the same time, unable to meet the actual needs. Therefore, an optimized energy-absorbing structure for bridge anti-collision facilities is proposed.
[0003] After retrieval, the existing patent application number is: CN202323042534.4, and the published patent name is: An optimized energy-absorbing structure for bridge anti-collision facilities, including a bridge body, on one side of which an anti-collision mounting plate is fixedly installed, on one side of which an energy-absorbing box body is movably installed, on one side of which an energy-absorbing box mounting plate is fixedly installed, and energy-absorbing mounting plate holes are all penetrated inside the energy-absorbing box mounting plate. On one side of the energy-absorbing box body, an energy-absorbing box connecting plate is fixedly installed, and energy-absorbing connecting plate holes are all penetrated inside the energy-absorbing box connecting plate. By fixedly installing an energy-absorbing box mounting plate on one side of the energy-absorbing box body, the utility model can buffer through the energy-absorbing outer buffer layer, then isolate the impact force by using the energy-absorbing outer isolation layer and the energy-absorbing inner isolation layer, and then buffer through the energy-absorbing inner buffer layer, and can absorb and buffer the impact force when the bridge is violently impacted, thereby reducing the damage to the bridge and improving the safety of the bridge anti-collision facilities.
[0004] However, when the above device is in use, since most bridge piers are columnar, the above device cannot protect multiple angles of the bridge pier, and there is room for improvement. Summary of the Utility Model
