Highway bridge collision prevention device

Abstract

The invention discloses a highway bridge collision prevention device, including mounting plate, a plurality of telescopic springs and fixing plates, the mounting plate is fixedly connected with the inner wall of a bridge handrail, The plurality of telescopic springs are uniformly arranged in parallel in the axial direction, one end of the telescopic spring is fixedly connected with the right sidewall of the mounting plate, the other end of each expansion spring is fixedly connected with the left side wall of the fixing plate, The right side wall of the mounting plate is also connected with anelastic plate, two sliding grooves are arranged below the expansion spring, the sliding grooves are embedded in the bridge deck, the sliding blocks are embedded in the sliding grooves, the two sliding blocks are respectively connected with the front bottom end and the rear bottom end of the fixing plate, and a driving motor is arranged on the side wall of the sliding blocks. Compared with the prior art, the anti-collision device of the highway bridge has good anti-collision effect, can effectively buffer the impact force of the vehicle on the bridge, on the one hand, effectively weakens the impact power and reduces the severity of the accident, on the other hand, weakens the damage of the impact on the highway bridge, and prolongs the service life of the hit structure of the highway bridge.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to an anti-collision device for highway bridges. Background technique [0002] With the development of science and technology, cars have become an essential travel tool for every household, but at the same time it also brings hidden dangers to people's safety. Highway bridges are frequent locations of traffic accidents, and the anti-collision devices of the highway bridges are particularly important. However, the anti-collision devices of the existing highway bridges have unsatisfactory anti-collision effects and cannot effectively buffer the impact force of vehicles on the bridge. On the one hand, the impact force cannot be effectively weakened, and the severity of the accident cannot be reduced; on the other hand, the damage to the road bridge without weakening the impact shortens the service life of the hit structure of the road bridge.
