Description

technical field

[0001] The invention relates to the technical field of height limiting devices, in particular to a bridge height limiting device with convenient adjustment. Background technique

[0002] A bridge (bridge) refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc. According to the structural system of bridges, there are four basic systems: girder bridge, arch bridge, rigid frame bridge, and suspension cable load-bearing (suspension bridge, cable-stayed bridge).

[0003] Bridge height limit is the main measure to restrict large vehicles from passing through important bridge sections. Every ye...
