Safety protective fence for road and bridge

Abstract

The invention discloses a safety protective fence for a road and bridge. The safety protective fence comprises a first mounting seat, a first stand column, a second stand column and a second mountingseat. The first stand column is fixedly mounted at the top of the first mounting seat, and the second stand column is fixedly mounted at the top of the second mounting seat. An upper mounting rod anda lower mounting rod are fixedly mounted between the first stand column and the second stand column and are in parallel. The upper mounting rod is located over the lower mounting rod. Four bearings are arranged on each of the upper mounting rod and the lower mounting rod. Rotating shafts are movably mounted between the upper mounting rod and the lower mounting rod through bearings, the number of the rotating shafts is four, and anti-collision columns are mounted on the outer sides of the four rotating shafts in a sleeving connection manner. Through the arrangement of a series of structures, the safety protective fence has the advantages of being convenient to mount and good in protective property.

Description

technical field [0001] The invention relates to the technical field of bridge guardrails, in particular to a safety guardrail for road bridges. Background technique [0002] Safety barriers are often set up on both sides of bridges to prevent cars from crashing out of the road when they encounter accidents, and to avoid greater casualties. The cushioning effect, and the ordinary slight collision will also cause deformation and damage to the guardrail, which needs to be disassembled and installed again, and the installation of the existing guardrail is complicated and troublesome. Most of them are fixed by various bolts, so that the installation It wastes time and consumes material resources. Therefore, in order to solve this series of problems, we have proposed a road and bridge safety fence to solve the problem. Contents of the invention [0003] The object of the present invention is to provide a safety barrier for road bridges to solve the problems raised in the above-...
