Abstract

The invention discloses a liftable guardrail for a bridge. The liftable guardrail comprises a bridge base (1) and a plurality of guardrail units (2) mounted on the bridge base (1), wherein each guardrail unit (2) comprises two fixed sleeve columns (4) which are bilaterally symmetrical and are fixed onto the bridge base (1), as well as an upper cross beam (21) and a lower cross beam (22) which extend across and beyond the two fixed sleeve columns (4); both the upper cross beam (21) and the lower cross beam (22) are provided with circuit devices and are fixedly connected by vertical rails (23); a screw hole matched with a vertical stud (43) in a threaded manner is formed in each of the two fixed sleeve columns (4); the upper end of the vertical stud (43) stretches into the upper cross beam (21) and is fixedly and axially 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 liftable guardrail for 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 bottom of the guardr...
