Bridge safety early warning component and early warning method based on tension and compression stress monitoring
The invention discloses a bridge safety early warning component and early warning method based on tension and compression stress monitoring, and belongs to the technical field of highway bridge monitoring, the component comprises a support, a tension and compression stress light-emitting piece and a photosensitive sensor, the tension and compression stress light-emitting piece and the photosensitive sensor are fixed on one side of the support, the support is connected to a stress monitoring part of a bridge, and a cylindrical boss is fixedly arranged on the support; the bottom of the cylindrical boss is axially provided with a column groove, a sliding ring is slidably arranged in the column groove, a plurality of sliding holes are annularly and evenly distributed in the cylindrical boss, ejector rods are slidably and cooperatively arranged in the sliding holes, the outer ends of the ejector rods extend out of the sliding holes, the inner ends of the ejector rods abut against one end face of the sliding ring, and a first elastic supporting device is arranged between the sliding ring and the support. A guide rod is fixed to the other end face of the sliding ring, and the guide rod penetrates through the support in a sliding mode and then is connected to the tension-compression stress light-emitting piece through a transmission assembly. According to the invention, the detection part of the bridge can be monitored in real time, the response to the structure state of the bridge is more visual, the monitoring is timely, and the monitoring result is more accurate.
本发明公开了一种基于拉压应力监控的桥梁安全预警构件及预警方法，属于公路桥梁监测技术领域，构件包括支架、固定在支架一侧的拉压应力发光片和光敏传感器，支架连接在桥梁的应力监测部位，支架上固定设置有柱形凸台，柱形凸台的底部沿轴向开设有柱槽，柱槽内滑动设置有滑环，柱形凸台上环形均布有若干滑孔，滑孔内滑动配合设置有顶杆，顶杆的外端向外伸出滑孔，顶杆的内端与滑环的一端面抵接，滑环与支架之间设置有第一弹性支撑装置，滑环的另一端面固定有导杆，导杆滑动穿过支架后通过传动组件连接至拉压应力发光片。本发明可以对桥梁的检测部位进行实时监控，对于桥梁结构状态的反应更为直观、监测及时、监测结果更为准确。
