Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: the existing plate-shaped guardrail is fixed to the bridge, and the bridge needs to be closed in extreme typhoon weather, but the erected plate-shaped guardrail is not enough to withstand the wind force, and the plate-shaped guardrail is prone to breakage accidents; When the weather is good, the plate-shaped guardrail blocks the sight of pedestrians, making it difficult for pedestrians to appreciate the scenery outside the bridge

The invention discloses a municipal bridge with liftable guardrails, and relates to the technical field of bridge engineering. The technical scheme includes that the municipal bridge comprises a bridge body and a plurality of guardrail plates arranged beside a bridge pavement, the guardrail plates are continuously arranged along the length direction of the bridge body and vertically and slidably arranged on the bridge body, driving plates inclined relative to a horizontal plane and vertical racks are fixed onto the guardrail plates, each tooth of the racks comprises a horizontal locking surface and an inclined guide surface positioned on the locking surface, a locking block and a torsion spring are rotatably arranged on the bridge body, the torsion spring drives the locking block to rotateand to be abutted to the locking surface, a trolley is slidably arranged in the bridge body along the length direction, and a driving portion and an unlocking rod are arranged on the trolley. The guardrail plates of the municipal bridge can be lifted up or down to meet the use requirements of different wind power for the guardrail plates, the guardrail plates of the municipal bridge can be conveniently lifted up or down only by controlling the trolley to move by staff, and automation degree is high.
Description
technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a municipal bridge with liftable guardrails. Background technique [0002] Municipal construction involves bridge engineering. Bridges are important transportation facilities connecting the two sides of the river. Bridges can be used for vehicles and pedestrians. There are generally guardrails on both sides of the road surface of the bridge, which can ensure the safety of vehicles and pedestrians. [0003] The Chinese utility model patent with the authorized announcement number CN205821998U discloses a bridge guardrail, which includes several support rods, and several groups of connecting rods are arranged between adjacent support rods, and the support rods correspond to the positions of the connecting rods. A connecting hole is provided, and the diameter of the inscribed circle of the connecting hole is larger than the diameter of the connecting rod; an elastic adjus...
