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 bridge road surface. On some bridge facilities, in order to provide lighting, aesthetics and safety indicator lights, the guardrails of bridges are often provided with electrical components such as circuits. Electrical components such as these circuits should often prevent water from entering and affecting normal use. At the same time, other devices that are easily affected by ponding or other road surface interference factors may also be installed at the bottom beam of the bridge guardrail, 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 avoid damage to the guardrail (especially the bot...
