Abstract

The invention relates to the technical field of highway guardrails, and discloses a forced movable energy-absorbing safety guardrail which comprises a base, a vertical pile is fixedly mounted at the top of the base, a vertical pile reinforcing plate fixedly connected with the vertical pile is fixedly mounted at the top of the base, and a connecting screw rod is inserted into the vertical pile. According to the forced movable energy-absorbing safety guardrail, during collision, an automobile body of an automobile can also make contact with a buffering ferrule and press the buffering ferrule and a connecting shaft, the automobile body moves relative to the buffering ferrule in the continuous moving process to absorb energy, impact borne by the connecting shaft is transmitted to a connecting plate and absorbed by the buffering spring, the connecting plate is limited by the limiting rod to transversely move towards a buckle plate, and after the limiting rod is deformed and staggered, the buckle plate and the connecting plate are matched in an internal flexible layer to deform and absorb impact energy, and finally the impact energy generated by collision is absorbed, so that the purpose of forced movable energy absorption is achieved.

Description

technical field

[0001] The invention relates to the technical field of expressway guardrails, in particular to a forced movable energy-absorbing safety guardrail. Background technique

[0002] Highway guardrail is the main form of semi-rigid guardrail. It is a continuous structure that is spliced ​​with corrugated steel guardrails and supported by main columns. The vehicle absorbs energy when it collides, and it is not easy to be crashed. At the same time, it can also play a very good role in protecting the vehicles, drivers and passengers. The bending of the expressway guardrail can increase the aesthetics and increase the strength of the guardrail at the same time.

[0003] According to the Chinese patent CN 107524107 A, a highway guardrail has a better buffering effect on the impact of vehicles, and the stronger the impact force of the vehicle, the more push blocks hit the baffle, so that the stronger the impact force of the vehicle, the greater the impact of the vehicle....
