Abstract

A bridge shake monitoring device disclosed by the present invention comprises a main body structure, a first detection structure and a second detection structure, the first detection structure is movably arranged in the main body structure and is located at the bottom, and the second detection structure is detachably arranged in the main body structure and is located at the top; the main body structure comprises a main body box, an isolation plate, a bearing and a touch screen; the invention relates to the technical field of bridge monitoring equipment, the equipment can be fixed on a bridge through the first fixing assembly, and the equipment can also be fixed on a bridge handrail through the second fixing assembly; data can be detected when the shaking amplitude of the bridge body is large through the first detection structure, and the vibration frequency can be expanded for collection through the second detection structure, so that the vibration data are collected; the overall structure is simple, the construction principle is simple, operation and use are convenient, overall installation and adjustment are rapid, and equipment can be conveniently operated and installed on a high bridge.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring equipment, in particular to a bridge shaking monitoring device. Background technique [0002] Bridges refer to buildings built for roads to cross natural or artificial obstacles. Refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; the auxiliary structures refer to bridge head buttresses, conical revetments, revetments, diversion works, etc.; [0003] Because some bridges are long, the force on the main body of the bridge will increase when the vehicle is running, especially in the middle of the bridge, which will cause the bridge body to vibrate or shake, which will cause danger to the overall bridge and traffic. Therefore, long-term monitoring of bridge-related information is required. , especially in weather such as earthquakes and strong winds, the shaking range of the bridge body will increase, which will make it more d...
