Abstract

A municipal bridge with a guardrail capable of ascending and descending comprises a bridge base body (1) and multiple guardrail units (2) installed on the bridge base body (1). Each guardrail unit (2) comprises two fixing sleeve uprights (4) symmetrically fixed to the bridge base body (1) left and right, an upper crossbeam (21) and a lower crossbeam (22), wherein the upper crossbeam (21) and the lower crossbeam (22) transversely stride over and extend to exceed the position between the two fixing sleeve uprights (4) and is each provided with a circuit device and fixedly connected through a vertical handrail (23). Each of the two fixing sleeve uprights (4) is provided with a screw hole in threaded fit with a vertical stud (43). The upper end of each vertical stud (43) extends into the upper crossbeam (21) and is axially and fixedly connected with the upper crossbeam (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 municipal 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...
