Road safety protection device

Abstract

The invention discloses a road safety protection device. The device comprises a guide guardrail device and a guide rod which are arranged on the two sides of a road in the road direction, wherein a plurality of rolling column devices are arranged on the guide guardrail device, and a rear support, a middle support and a front support corresponding to the rolling column devices are sequentially arranged on the guide guardrail device from back to front; the rear support, the middle support and the front support are connected in a sliding mode through the guide rods, the rolling column devices are connected through the bendable energy release connection plates, energy release modes are diversified, the energy release effect is good, the bendable energy release connection plates and the buffering sliding grooves are arranged, the buffering effect can be better improved, and the situation that the rolling column devices are broken due to collision due to too large rigidity is avoided.

Description

technical field [0001] The invention relates to the technical field of road safety devices, and relates to a guide sliding surface energy release guardrail on both sides, a central isolation guardrail and an energy release safety device during braking activities, and in particular to a road safety protection device. Background technique [0002] When the vehicle is running on the road, some vehicles often have brake failure, especially on roads with long slopes in mountainous areas. For this reason, special avoidance lanes are usually set up, and in the avoidance lanes, there are usually set Collision energy-absorbing devices are used to protect vehicles that are forced to enter the avoidance lane due to brake failure. The current energy-absorbing devices generally use waste rubber tires, aggregate piles or energy-absorbing barrels, etc. These energy-absorbing facilities generally have unstable energy-absorbing effects , may produce excessive collision impact force, affectin...

[0002] When the vehicle is running on the road, some vehicles often have brake failure, especially on roads with long slopes in mountainous areas. For this reason, special avoidance lanes are usually set up, and in the avoidance lanes, there are usually set Collision energy-absorbing devices are used to protect vehicles that are forced to enter the avoidance lane due to brake failure. The current energy-absorbing devices generally use waste rubber tires, aggregate piles or energy-absorbing barrels, etc. These energy-absorbing facilities generally have unstable energy-absorbing effects , may produce excessive collision impact force, affecting the safety of the vehicle or passengers, and some other existing protective devices are mostly rigid connections without buffer sections, which are easily deformed and damaged under strong impact force. It has no energy release function. When it is hit by a high-speed or large vehicle, it cannot release energy in time, which may easily lead to rollover or overturning in an emergency stop, posing a traffic safety hazard. However, some structures with energy release have a single energy release effect. not good
