A kind of ramp protection device and using method

Abstract

The invention discloses a ramp entrance protection device and a use method thereof, which solves the problem in the prior art that if a vehicle collides at a ramp entrance, the buffering capacity of a hard collision is poor, and has the ability to improve a better buffering effect for the vehicle, and to The kinetic energy of the vehicle can be effectively dispersed and stored, and the beneficial effect of improving the kinetic energy absorption rate of the vehicle collision is as follows: a protective device for a ramp, including elastic protective components, is arranged at the bifurcation point of the ramp, and the protective component is relatively The ground is movable; the connecting body is movably arranged on both sides of the protective component, and is arranged along the side of the road on the side of the bifurcation point, and the connecting body is connected with the protective component.

Description

A kind of ramp protection device and using method technical field [0001] The present invention relates to the field of road safety, in particular to a ramp protection device and a method of use. Background technique Driven by the rapid development of highway construction, the construction of highways in my country has been popularized, and the number of vehicles has increased sharply. add. In this context, there are often more diversions or exits on main roads and expressways. Usually, due to driving Due to reasons such as the inattention of the personnel, the vehicle stops at the ramp entrance or hits the roadblocks and fixed protective devices at the ramp entrance. Vehicles and people pose a greater risk. In addition, it may further cause the rear vehicle to fail to change lanes in time or fail to raise the The collision with the accident vehicle at the ramp crossing occurs again after predicting the situation of the vehicle ahead, and then evolves into a larger...

AI Technical Summary

Problems solved by technology

When the vehicle collides at the fork of the ramp, the vehicle can only deform the vehicle and personnel through a hard collision with the anti-collision bucket or anti-collision plate to reduce the injury of the vehicle and personnel, and the overall anti-collision device is an independent device, due to the limited buffer capacity , the safety of the corresponding vehicles and personnel is still low. In some special cases, due to the high speed of the vehicle, the vehicle may damage the guardrail at the ramp entrance, and the damaged guardrail parts penetrate into the interior of the vehicle, causing secondary damage to the personnel in the vehicle. secondary injury

[0004] In addition, after the vehicle collides at the bifurcation of the ramp, the subsequent vehicles will not evade in time, which may easily cause secondary accidents.
