Anti-collision device of highway bridge

Abstract

The invention discloses an anti-collision device of a highway bridge, and relates to the field of bridge safety. The anti-collision device comprises a plurality of buffering devices evenly arranged inthe left-right direction. Each buffering device comprises a fixed box. The upper end face of the rear portion of each fixed box is fixedly connected with a blocking rod. A containing groove penetrates through the lower portion of each blocking rod in the front-back direction. The upper ends of the blocking rods are fixedly connected with backflush devices. Mounting grooves penetrate through the backflush devices in the front-back direction. The rear potions of the mounting grooves are in front-back sliding connection with balance weights. The front portions of the mounting grooves are in front-back sliding connection with balance weights. The anti-collision device has the advantages that three times of buffering are carried out through buffering tension springs, buffering compressed springs and explosives, and the impact force of cars is reduced to the maximum degree; after a car collision, upper buffering rods and lower buffering rods are bent, and by means of the oblique state of inclined rods, the cars are not likely to fly out accordingly.

Description

technical field [0001] The invention relates to the technical field of bridge safety. Background technique [0002] Guardrails are generally installed on both sides of the bridge, and the connection between the guardrail and the bridge is generally fixed by screws. If a vehicle hits the guardrail, the general guardrail cannot block the impact of the vehicle and the vehicle will fly out. And because the guardrail and the bridge are fixedly connected, after the car hits the guardrail, it will cause great damage to the bridge. After multiple damages, the bridge may not be used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-collision device for highway bridges in view of the above technical deficiencies. Use the buffer tension spring, buffer compression spring, and explosives for three times of buffering to minimize the impact of the car; after the car collides, the upper buffer rod and the lower buffer ro...
