A kind of highway reinforced protective fence

Abstract

The invention discloses a highway reinforced guardrail, comprising a trapezoidal base, a base column is movably connected to the top of the trapezoidal base, and a guardrail main body is movably connected to one end of the base column away from the trapezoidal base, and the guardrail main body is movable away from the top of the base column A top seat post is connected, one end of the top seat post away from the guardrail main body is movably connected with a crossbar, and a side of the crossbar away from the top seat post is movably connected with a protective pad; the guardrail main body includes a clamping outer ring mechanism, The top and bottom of the inner surface of the outer ring mechanism of the clamping position are movably connected with an inner strengthening mechanism, and the invention relates to the technical field of highways. Through the multilateral design of the internal strengthening mechanism itself, the balance and stability of the component itself when it is toppled is increased, the directional restriction of the impacted vehicle is carried out, the non-directional swing is avoided, the surrounding safety is protected, the contact area with the ground is increased, and the The effect of deceleration, strengthen the energy of vehicle braking, improve safety performance.

Description

technical field [0001] The invention relates to the technical field of highways, in particular to a reinforced protective fence for highways. Background technique [0002] The protective structure of the safety guardrail beside the existing road is generally a protective plate, and the protective plate is mostly bent to form an arc-shaped plate structure by metal materials. The arc-shaped plate structure can provide a certain buffer force to reduce impact damage. [0003] According to the Chinese patent CN112160275A, no welding is required in the whole process, and the assembly efficiency is high; when it is necessary to replace several extension springs, it is only necessary to take out the two rectangular strips and several extension springs from the cavity, which is convenient and efficient; The upper and lower sides of the front fence and the upper and lower sides of the rear fence are preset with outward tension, so that the upper and lower ends of the front fence can b...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a road reinforced guardrail, which solves the problem of the existing road reinforced guardrails being set in an arc shape when the front fence and the rear fence are in use, and their own balance performance after a collision. Poor, easy to tilt, causing it to guide the vehicle in a non-directional manner, difficult to control, and endangering the safety of the surrounding area
