Active bridge anti-collision device

Abstract

The invention relates to an active bridge anti-collision device. According to the technical scheme, the device comprises a vertical pipe, wherein a plurality of first rollers capable of elastically extruding a bridge pier are evenly distributed on the inner edge face of the vertical pipe, a hollow cylindrical cavity is coaxially fixed to the lower half portion of the outer circle face of a round pipe, an air bag is arranged in the cavity, the air bag is connected with an air supply device fixed to a bridge plate through an air pipe, a conical barrel with openings in the upper end and the lowerend is coaxially arranged above the cavity, a driving device capable of driving the conical barrel to rotate around the axis of the vertical pipe is arranged in the conical barrel, a plurality of supporting shafts parallel to the generatrix of the inclined face are evenly distributed on the circumference of the inclined face of the conical barrel, the distances between the supporting shafts and the inclined face are sequentially increased and then decreased, each supporting shaft is sleeved with a plurality of second rollers at intervals, the outer side of the bridge pier is further sleeved with a floating plate arranged above the vertical pipe, and a plurality of inductive switches are arranged on part of the circumference of the floating plate in the radial direction of the bridge pier.

Description

technical field [0001] The invention relates to the field of bridge anti-collision, in particular to an active bridge anti-collision device. Background technique [0002] A bridge placed above a river may collide with the pier when a boat passes by, causing damage to the hull and the pier. To achieve a buffering effect, the anti-collision equipment of the bridge pier at this stage is either fastened to the pier or floats on the water. This type of anti-collision equipment causes the outer diameter of the pier to become larger, narrowing the passage for boats, and The bridge anti-collision equipment existing on the water surface has been subjected to water erosion for a long time and friction with the bridge piers will also cause wear and tear on the bridge piers and anti-collision devices, and the traditional bridge anti-collision equipment is buffered or driven after being passively impacted. To a certain extent, it will still cause damage to the pier, and the cushioning e...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an active bridge anti-collision device, which effectively solves the problem that the current bridge anti-collision equipment is fixed or placed on the water surface, causing the diameter of the bridge pier to become larger, and the boat corridor Narrowing, while increasing the problem of wear between the piers and the anti-collision equipment

[0005] The present invention is novel in concept, ingenious in structure, and strong in practicability, and effectively solves the problem that bridge pier diameters become larger and ship corridors become narrower due to fixed or placed bridge anti-collision equipment at the current stage, while increasing the distance between bridge piers and anti-collision equipment. wear-and-tear problem
