AI Technical Summary

Technical Problem

The protective brackets of existing road guardrails cannot adjust the height, resulting in the inability to adjust according to different usage occasions. At the same time, the structure is complex and there are many parts, making it inconvenient to install and disassemble.

Method used

A road guardrail protection bracket including a pillar and a pillar is designed. By setting a reinforcement group between the pillars, the height of the protective rod is adjusted by sliding the lifting column in the sliding cavity, and the lifting column and the pillar are fixed through threaded connections between the locking bolts and the mounting holes, simplifying the installation and disassembly process.

Benefits of technology

The height adjustment of the protective bracket is realized to adapt to the use of different demand locations. At the same time, by simplifying the structure and reducing parts, the convenience of installation and disassembly and the overall strength of the device are improved.

Abstract

The protective support of the road guardrail comprises supporting columns and supporting rods, a plurality of sets of supporting columns are arranged, sliding cavities are formed in the inner walls of the supporting columns, lifting columns are arranged in the sliding cavities in a sliding mode, two sets of sleeves are symmetrically welded to the two side walls of each lifting column, and protective rods are connected to the inner walls of the two sets of sleeves in an inserted mode. The overall strength of the device can be enhanced by arranging the reinforcing sets between the adjacent supporting columns, the protection height of the protection rods can be adjusted through sliding of the lifting columns in the sliding cavities, and therefore the device can be used in places with different requirements conveniently; the lifting columns and the supporting columns can be fixed through threaded connection between the locking bolts and the mounting holes with the corresponding heights.
