Abstract

A bridge with lifting type guardrails comprises a bridge base body (1) and a plurality of guardrail units (2) installed on the bridge base body (1). Each guardrail unit (2) comprises two fixed sleeve stand columns (4), an upper cross beam (21) and a lower cross beam (22), wherein the two fixed sleeve stand columns (4) are fixed on the bridge base body (1) in a left-right symmetry mode; the upper cross beam (21) and the lower cross beam (22) stretch across, extend and exceed the two fixed sleeve stand columns (4); the upper cross beam (21) and the lower cross beam (22) are both provided with circuit elements and fixedly connected through vertical guardrails; each of the two fixed sleeve stand columns (4) is internally provided with a screw hole in thread fit with a vertical stud (43); and the upper end of each vertical stud (43) extends into the upper cross beam (21) and axially and fixedly connected with the upper cross 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 bridge with liftable guardrails. 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 bottom of the guard...
