Road and bridge safety anti-collision guardrail based on inertial principle

Abstract

The invention discloses a road and bridge safety anti-collision guardrail based on an inertial principle. The road and bridge safety anti-collision guardrail comprises a bottom plate; the top of the bottom plate is provided with sliding grooves and a damping device, the sliding grooves are located on both sides of the damping device, and the tops of the sliding grooves are slidably connected withanti-collision side plates; the two anti-collision side plates are fixedly connected through a fist spring, and a buffering device is arranged in the up-down direction of the damping device and can make the anti-collision side plates to be delayed reset; no less than four connecting rods are movably mounted to the left side and the right side of the damping device correspondingly, and the two connecting rods on the same side are movably connected through a rotating shaft in a cross mode; and first connecting pieces are fixedly mounted at the other ends of the connecting rods correspondingly, and the first connecting pieces are connected with the anti-collision side plates through grooves. The road and bridge safety anti-collision guardrail based on the inertial principle has the characteristics of anti-collision damping, protection of automobiles, the long service life and the like.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a safety anti-collision barrier for roads and bridges based on the principle of inertia. Background technique [0002] There are anti-collision guardrails on both sides of the road or in the middle of the road, mainly to maintain and protect road safety. The current anti-collision guardrails are mostly welded by steel bars, and there is no buffering effect. Deformation, it is easy to scratch the car, and when the impact force is large, the protective plate will be broken, causing safety hazards and short service life. [0003] As a disc-shaped part with a large moment of inertia, the flywheel generally functions as an energy storage. It also has another characteristic, that is, the initial speed of rotation is relatively slow, so that the release of energy can be delayed. Contents of the invention [0004] The technical problem solved by the present invention is to o...
