Collision energy absorption device of emergency lane

Abstract

The invention discloses a collision energy absorption device of an emergency lane. The collision energy absorption device mainly comprises a fastened barrier, constraint enclosing walls and an energy absorption baffle, wherein the energy absorption baffle has the function of absorbing energy, the constraint enclosing walls can prevent vehicles from tilting, and the fastened barrier can stop vehicles out of control, so that the vehicles cannot continue to go forward . A set of collision energy absorption device is mounted at the tail end of the emergency lane, when a vehicle runs down a long slope, the brake of the vehicle is invalid, and the vehicle is forced to run into the emergency lane, so that vehicles running at different speeds can be guaranteed to be braked by a braking bed of the emergency lane in a limited distance at first, and then are forced to pass through the collision energy absorption device mounted at the tail end of the emergency lane, and finally, the vehicles stop safely and reliably.

Description

technical field [0001] The invention belongs to road safety protection devices, in particular to a collision energy-absorbing device for an avoidance lane. Background technique [0002] There are some downhill and long slope lanes in mountainous areas that often cause the brakes of some vehicles to fail. For this reason, there are special avoidance lanes. The brake bed of the avoidance lane can force the vehicle to brake and stop. However, the avoidance lane is often difficult to have sufficient braking distance due to site restrictions. The avoidance lane collision energy-absorbing device is used to protect vehicles forced to enter the avoidance lane due to brake failure. Existing devices generally use waste rubber tires, aggregate piles, and energy dissipation barrels. These energy dissipation facilities generally have unstable energy absorption effects, unstable energy absorption performance, and may generate excessive collision impact. After the vehicle collides with t...

Problems solved by technology

Existing devices generally use waste rubber tires, aggregate piles, and energy dissipation barrels. These energy dissipation facilities generally have unstable energy absorption effects, unstable energy absorption performance, and may generate excessive collision impact force

After the vehicle collides with the energy-absorbing facilities, uncontrollable material scatter will occur, which may lead to a secondary collision with the vehicle and threaten the safety of the vehicle and the passengers; at the same time, the state of the vehicle during the collision is unrestricted, and rollover may occur, resulting in serious ACCIDENT
