Road anti-collision buffer device

Abstract

The invention relates to the field of municipal road construction, in particular to a road anti-collision buffer device. The device comprises a base, a U-shaped plate is fixed at one end of the base,openings in the two ends of the U-shaped plate face the other end of the base, the base is hollow, a collision plate is arranged between the inner walls of the two ends of the U-shaped plate, a firstbuffer piece used for buffering the impact force of an accident vehicle is arranged between the U-shaped plate and the impact plate, a mounting hole is formed in the upper surface of the base, one endof the mounting hole is positioned in an inner cavity of the U-shaped plate, the other end is positioned outside the U-shaped plate, a second buffer piece for delaying the collision time of the accident vehicle and the collision plate is arranged in the mounting hole, a plurality of first air bags are fixed to the inner wall of the U-shaped plate, air storage pieces used for inflating the first air bags are arranged on the inner walls of the two sides of the base, a vehicle is wrapped by the first air bags on the two sides of the U-shaped plate, the vehicle body is hindered, the speed of thevehicle is decreased, meanwhile, friction between the vehicle and the inner wall of the U-shaped plate is reduced, and vehicle damage is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal road construction, in particular to a road anti-collision buffer device. Background technique [0002] Municipal roads refer to the roads that lead to various areas of the city, are used for transportation and pedestrians in the city, are convenient for residents' life, work, cultural and entertainment activities, and are connected with roads outside the city to bear external traffic. [0003] The utility model of the notification number CN208055932U discloses a kind of anti-collision barrel for municipal road vehicle direction indication, including a first anti-collision barrel and a second anti-collision barrel, the first anti-collision barrel and the second anti-collision barrel have the same structure, so The first anti-collision bucket and the second anti-collision bucket are connected by a horizontal bar, the bottom end of the first anti-collision bucket is provided with a base, and the mi...
