Safety guardrail with adjustable protection height

Abstract

The invention discloses a protective-height-adjustable safety guardrail which comprises at least two bases, stand columns are fixedly installed at the upper ends of the bases, lifting rods are arranged at the upper ends of the stand columns, and a lower protective mechanism is fixedly connected between the two stand columns. An upper protection mechanism is fixedly connected between the two lifting rods jointly, two buffer devices are fixedly installed at the front end and the rear end of the lower protection mechanism in a bilateral symmetry mode, and anti-collision plates are fixedly installed at the ends, away from the lower protection mechanism, of the two buffer devices located in front of and behind the lower protection mechanism jointly. A connecting piece is further arranged between every two adjacent stand columns. According to the safety guardrail capable of adjusting the protection height, the height of the guardrail can be effectively adjusted, operation is easy and convenient, the guardrails are connected with one another, the placing angle can be adjusted at will, and the safety guardrail has good anti-collision performance when colliding occurs and is suitable for being widely used and popularized.

Description

technical field

[0001] The invention relates to the field of protection facilities, in particular to a safety guardrail capable of adjusting the protection height. Background technique

[0002] With the continuous development of the economy and society, the continuous improvement of people's living standards, and the continuous increase in the number of motor vehicles, protective fences are often used to divide the roads in urban roads to ensure safety and smooth traffic.

[0003] The road guardrail belongs to the public transportation infrastructure, and it is an important guarantee facility for maintaining and protecting road safety. The function of the road guardrail on the road is to distinguish lanes, ensure that vehicles drive according to the lane, and ensure traffic safety. At the same time, it can also block the headlights of the opposite lane at night, further ensuring the safety of driving. Most of the current guardrails are made up of many cut small guardrails p...
