Abstract

A lifting guardrail device used for a municipal bridge comprises a bridge matrix (1) and a plurality of guardrail units (2) mounted on the bridge matrix (1). Each guardrail unit (2) comprises two fixed sleeve columns (4) fixed on the bridge matrix (1) bilaterally symmetrically, as well as an upper beam (21) and a lower beam (22) which cross and extend over the two fixed sleeve columns (4), wherein each of the upper beam (21) and the lower beam (22) is provided with circuit apparatus, and the upper beam (21) and the lower beam (22) are fixedly connected through vertical railings (23); a screw hole in threaded fit with a vertical stud (43) is formed in each of the two fixed sleeve columns (4), and the upper end of the vertical stud (43) extend into the upper beam (21) and is axially and fixedly connected with the upper beam (21) through an upper thrust bearing (431) and a lower thrust bearing (432).

Description

Technical field [0001] The invention relates to the field of bridges, in particular to a liftable guardrail device for municipal bridges. Background technique [0002] There are often guardrails on both sides of the road surface of the bridge to ensure traffic safety on the road surface of the bridge. In some bridge facilities, in order to provide lighting, aesthetics and safety indicators, the guardrails of the bridge are often equipped with electrical components such as circuits. However, these circuits and other electrical components should often avoid the entry of water and affect normal use. At the same time, the bottom beam of the bridge guardrail may also be equipped with other devices that are easily affected by stagnant water or other road interference factors, such as some sensing devices or beautiful decorative materials. Therefore, in some specific situations, it becomes necessary to adjust the height of the guardrail to prevent the guardrail (especially the bottom ...
