Abstract

A liftable bridge guardrail device comprises a bridge base body (1) and multiple guardrail units (2) mounted on the bridge base body (1), wherein each guardrail unit (2) comprises two fixed sleeve stand columns (4) fixed on the bridge base body (1) in a leftwards and rightwards symmetric manner as well as an upper cross beam (21) and a lower cross beam (22) which stretch across and extend out of the space between the two fixed sleeve stand columns (4), the upper cross beam (21) and the lower cross beam (22) are provided with circuit devices and are fixedly connected with each other by the aid of vertical rails (23), a screw hole in threaded fit with a vertical stud (43) is formed in each of the two fixed sleeve stand columns (4), and the upper end of each vertical stud (43) extends into the upper cross beam (21) and is axially and fixedly connected with the upper cross beam (21) by the aid of 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 bridge guardrail device. 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 guar...
