Highway emergency protection device

Abstract

The present invention relates to the technical field of traffic safety accessory devices, in particular to an emergency avoidance protection device for highways, which can improve the deceleration ability of automobiles, can effectively decelerate automobiles with large kinetic energy until they stop, and improve safety; and can Effectively prevent the car from stopping and the cargo rushing out due to inertia, avoiding losses; including sequentially connected driving-in area, first deceleration area, first buffer area, second deceleration area, second buffer area, and third deceleration area and the collision buffer zone, both ends of the first deceleration area are provided with triangular supports, and multiple sets of roller shafts are arranged between the two sets of triangular supports, and the two ends of the multiple sets of roller shafts are rotationally connected with the two sets of triangular supports through ball bearings. The first buffer zone is provided with the first interception net, the second deceleration zone is provided with artificial sand, the second buffer zone is provided with the second interception net, the third deceleration zone is provided with medium sand, and the collision buffer zone is provided with anti-collision barrels and elastic damping plate.

Description

technical field [0001] The invention relates to the technical field of traffic safety accessory devices, in particular to an emergency avoidance protection device for expressways. Background technique [0002] As we all know, expressways in mountainous areas often encounter continuous long and steep downhill. Due to the existence of continuous long and steep downhill, it is easy for vehicles to lose control of their speed and brake failure, resulting in accidents. The second expressway emergency avoidance protection The device is an auxiliary device used to enable the out-of-control vehicle to leave the main lane and decelerate safely until it stops to avoid accidents. It has been widely used in the field of mountainous expressways; Including the drive-in zone, deceleration zone and collision buffer zone, the input end of the drive-in zone is connected to the main lane, the output end of the drive-in zone is connected to the input end of the deceleration zone, and the output...

[0002] As we all know, expressways in mountainous areas often encounter continuous long and steep downhill. Due to the existence of continuous long and steep downhill, it is easy for vehicles to lose control of their speed and brake failure, resulting in accidents. The second expressway emergency avoidance protection The device is an auxiliary device used to enable the out-of-control vehicle to leave the main lane and decelerate safely until it stops to avoid accidents. It has been widely used in the field of mountainous expressways; Including the drive-in zone, deceleration zone and collision buffer zone, the input end of the drive-in zone is connected to the main lane, the output end of the drive-in zone is connected to the input end of the deceleration zone, and the output end of the deceleration zone is connected to the input end of the collision buffer zone , and the deceleration zone and the collision buffer zone have a certain slope, the deceleration zone is paved with artificial sand, and the collision zone is provided with elastic damping plates; Drive into the deceleration zone from the drive-in zone, decelerate the car through the friction between artificial sand and tires, and provide final protection to the car through the damping plate to stop the car completely; the existing expressway emergency avoidance protection device In use, it is found that due to the overspeeding and overloading of many cars, it is difficult to slow down to a stop for some cars with very large kinetic energy, resulting in accidents and low safety; and it only decelerates for the bottom tires of the car, which is easy Causes the car to stop, but the cargo rushes out due to inertia, causing losses
