Problems solved by technology

[0004] The object of the present invention is to provide an anti-collision device for bridges, which performs primary buffering through airbags, secondary buffering through filling bags, tertiary buffering through rubber plates and closed-cell foam aluminum plates, and secondary buffering through first steel plates and second steel plates. Improve the strength of the protective device, and drive the propeller to rotate through the motor to drive the entire anti-collision device to rotate along the pier, which plays the role of unloading force and solves the problem of insufficient protection capacity of the existing anti-collision device

Abstract

The invention discloses an anticollision device of for bridge girders and relates to the technical field of bridge girder protection. The anticollision device for the bridge girders comprises eight protection devices and eight floating capsules. The number and shape of the protection devices and the floating capsules are corresponding to the number and shape of the bridge girders needed to be protected in actual use. Each protection device comprises a first steel plate. A rubber sheet, a closed-cell foam aluminium plate and a second steel plate are sequentially fixed from the inside to the outside on one surface of the first steel plate through a first bolt and a second bolt. A filling capsule is fixed to one surface of the second steel plate through an adhesive. According to the anticollision device for the bridge girders, first-level buffering is conducted through capsules; second-level buffering is conducted through the filling capsule; third-level buffering is conducted through therubber sheet and the closed-cell foam aluminium plate; the strength of the protection devices are elevated through the first steel plate and the second steel plate; propellers are driven to rotate through a motor, and thus the whole aiticollision device is driven to rotate along the corresponding bridge girder; the force-discharging effect is achieved; and the problem that protection capability of an existing anticollision device is insufficient is solved.

Description

technical field [0001] The invention belongs to the technical field of bridge protection, in particular to a bridge anti-collision device. Background technique [0002] At present, most navigable bridges in my country do not have anti-collision facilities, and it is difficult to avoid the huge damage caused by ship collision accidents. Therefore, from the perspectives of safety, economy, and environmental protection, it is urgent to design economical and reasonable bridge anti-collision devices. question. [0003] Traditional bridge anti-collision devices are installed integrally on the outer surface of the bridge pier, and most of them use a single layer of material for protection. However, the protection performance is insufficient, and the buffer force is insufficient to achieve a good protection effect when the ship hits, which will reduce the service life of the bridge pier. problems, thus reducing the service life of the bridge. At the same time, the integrated anti-co...
