Abstract

The invention relates to a bridge with liftable guardrails and capable of preventing over travel. The bridge comprises a bridge matrix (1) and a plurality of guardrail units (2) mounted on the bridge matrix (1), wherein each of the guardrail units (2) comprises two fixing sleeve vertical columns (4), an upper crossbeam (21) and a lower crossbeam (22), wherein the fixing sleeve vertical columns (4) of each guardrail unit (2) are fixed to the bridge matrix (1) in a left-right symmetrical manner; the upper crossbeam (21) and the lower crossbeam (22) of each guardrail unit (2) cross and extend to exceed the positions of the two corresponding fixing sleeve vertical columns (4); circuit devices are separately arranged on each upper crossbeam (21) and each lower crossbeam (22) and are fixedly connected by vertical guardrails (23); a screw hole being matched with a vertical screw column (43) is formed in each of every two fixing sleeve vertical columns (4); and the upper end of each of the vertical screw columns (43) extends into the corresponding upper crossbeam (21) to be axially and fixedly connected with the corresponding 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 bridge with liftable guardrails and overtravel prevention. 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 (especial...
