Buffer type highway guardrail for hillside dangerous road

Abstract

The invention discloses a buffer type highway guardrail for a hillside dangerous road. The buffer type highway guardrail includes two handrails, the opposite side walls of the two handrails are jointly and fixedly connected to a buffer strip, a buffer mechanism is arranged on the buffer strip and the two handrails jointly, the buffer mechanism comprises a mounting cavity formed in the buffer strip, a fixed plate is fixedly connected to the inner wall of the mounting cavity, traction ropes are fixedly connected to the two side walls of the fixed plate, control cavities are formed in the two handrails, and rotating rods are rotatably connected to the bottoms in the two control cavities correspondingly, reels are fixedly connected to the side walls of the two rotating rods correspondingly, gears are fixedly connected to the side walls of the two rotating rods correspondingly, racks engaged with the two gears are arranged in the two control cavities correspondingly, and electric contacts are fixedly connected to the side walls of the two racks correspondingly. Under the condition that a vehicle does not rush out of the road, the vehicle speed of the vehicle is gradually reduced, thus guaranteeing that passengers in the vehicle cannot suffer large impact force to cause danger.

Description

technical field [0001] The invention relates to the technical field of highway guardrails, in particular to a buffer-type highway guardrail used for dangerous roads near mountains. Background technique [0002] Dangerous roads near mountains in mountainous areas are one of the frequent places for vehicle accidents. Dangerous roads near mountains are generally close to mountains on the inside, and rivers or cliffs on the outside. Moreover, dangerous roads near mountains have more curves and sharper curves. Compared with urban roads If the vehicle deviates from the road when driving, it will cause serious consequences. Therefore, guardrails are usually installed on the outside of the road to prevent vehicles from rushing out of the road due to high speed and falling into rivers or cliffs. However, the existing guardrails There are the following problems: [0003] 1. The existing guardrails are usually made of relatively hard metal. When the vehicle speed is slow, the vehicle ...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing guardrails are usually made of relatively hard metal. When the vehicle speed is slow, the vehicle will hit the guardrail, which will cause the vehicle to stop quickly and cause a great impact on the passengers in the car. Although it can prevent The vehicle falls, but a large impact will also cause serious danger to the passengers in the vehicle;

[0004] 2. When the vehicle is driving fast, if the vehicle hits the guardrail, it will even break the guardrail directly, and then rush out of the road, causing serious consequences
