Problems solved by technology

[0003] The guardrails at the existing ramp entrances are all made of steel plates. When the vehicle collides with the guardrails when driving at high speed, the collision of the vehicle often leads to car crashes and fatalities, resulting in great economic losses and casualties.

Embodiment Construction

[0032]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] like Figure 1-7 As shown in the figure, a method for protecting a highway ramp crossing is characterized by comprising the following steps:

[0034] S1. Set up protective devices at the intersection of the expressway ramp;

[0035] like Figure 1-7 As shown, the protective device includes a base 100 , an energy absorbing mechanism 200 , a supporting mechanism 400 distributed on both sides of the energy absorbing mechanism 200 and used for supporting the energy absorbing mechanism 200 , and a guiding mechanism 300 . The base 100 is used to be installed on the ground along the extending direction of the road surface; the energy-absorbing mechanism 200 is slidably connected to the base 100, and the energy-absorbing mechanism 200 is slidably connected to the base...

Abstract

The invention discloses a highway ramp protection method. The highway ramp protection method is characterized by comprising the following steps that S1, a protection device is arranged at a highway ramp; s2, when the vehicle is out of control and collides with an energy absorption mechanism (200) of the protection device, a rotary drum assembly (230) in the energy absorption mechanism rotates to convert impact force of the vehicle out of control into acting force of the vehicle in the extending direction of the road surface so as to guide the vehicle out of control to run in the extending direction of the road surface; and S3, the energy absorption mechanism (200) subjected to the impact force converts component force of the impact force along the road surface in the width direction of the base into power for pushing out the guide mechanism (300) through the upper end of the supporting mechanism (400), so that the side, close to the road surface, of the guide mechanism (300) and the outer side of the rotary drum assembly (230) make contact with the out-of-control vehicle at the same time, and the out-of-control vehicle is guided to extend in the direction of the road surface.

Description

technical field [0001] The invention relates to the technical field of highway ramp crossing protection, in particular to a highway ramp crossing protection method. Background technique [0002] The expressway ramp intersection refers to the section where two roads are connected on the expressway or the section that enters the expressway, and also refers to the section where the expressway is connected to the adjacent auxiliary road. Driving too fast on the ramp to collide with the barrier of the ramp, or colliding with the barrier of the ramp due to excessive speed while turning the ramp. [0003] The guardrails at the existing ramp entrances are all made of steel plates. Under the condition of high-speed driving, when the vehicle collides with the guardrail, the collision of the vehicle often leads to the death of the vehicle, resulting in great economic losses and casualties. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a protect...
