Expressway tunnel traveling safeguard device

Abstract

The invention discloses an expressway tunnel traveling safeguard device. The expressway tunnel traveling safeguard device comprises deceleration guiding devices arranged at intervals on the cover plates of cable ducts in the two sides of the inner pavement of an expressway tunnel. Each deceleration guiding device comprises through grooves formed in the wheel guiding surfaces of the cover plates, arotary shaft is installed on the edge of one side of the through grooves, a pressing plate and a rotary plate are arranged on the rotary shaft, wherein the pressing plate is located on the inner sideof the wheel guiding surface, and a first spring is arranged between the pressing plate and the wheel guiding surface; one end of the rotary plate penetrates through the through grooves and is located under the through grooves, and a decelerator is connected to the end of the rotary plate through a bending part; when the first spring is pressed because the pressing plate is under pressing force,the rotary plate rotates around the rotary shaft and drives the decelerator to move to the upper part of the through grooves; and guiding cylinders are arranged on the side, on the inner walls of thetunnel, of each cable duct. According to the expressway tunnel traveling safeguard device, automobile wheels can be decelerated, driving directions are further corrected, so that wheels on one side ofthe vehicle is at last stopped on the wheel guiding surfaces of the cover plates and the occurrence of conditions such as automobile yawing and rollover caused by losing control of the wheels is avoided.

Description

technical field [0001] The invention relates to the technical field of road traffic safety, in particular to a driving safety protection device for expressway tunnels. Background technique [0002] With the rapid development of expressways in my country, expressways gradually extend to tunnels in mountainous areas. Due to the particularity and complexity of address structures in mountainous areas, the number of expressway tunnels in mountainous areas continues to increase, and tunnel driving safety has become a new focus of work. [0003] Taking Lianhuo Expressway as an example, Lianhuo Expressway is an important traffic artery on the east-west trunk line in my country, and it is also the longest expressway in China, passing through six provinces of Jiangsu, Anhui, Henan, Shaanxi, Gansu, and Xinjiang, including Baoji to Tianshui Due to the concentration of mountains, there are nearly 40 tunnels in this section alone. There are many long tunnels and extra-long tunnels, such a...

AI Technical Summary

Problems solved by technology

The main reason for this type of accident is: due to the dark light in the tunnel, the surrounding environment does not change significantly, especially for long tunnels, when the driver is driving in a dark environment, he is prone to fatigue or blurred vision, resulting The vehicle deviates from the driving track and hits the curb under imperceptible circumstances; or the driver does not grasp the wheel position when avoiding the car and hits the curb

Regardless of the reason, when the vehicle hits the curb at a relatively high speed (such as the speed limit of the Gansu section of the Lianhuo Expressway at 60km / h), the front tire on one side of the vehicle rushes onto the curb, which may cause the vehicle to roll over or sway. cause traffic accident
