Self-sensing anti-beam-falling device
The invention provides a self-sensing anti-beam-falling device, which belongs to the technical field of anti-beam-falling, and comprises a transition steel rod, two groups of anchoring assemblies, a telescopic assembly and two groups of first strain sensors, the two ends of the transition steel rods are arranged on the two adjacent beam bodies respectively. The two anchoring assemblies are correspondingly arranged at the two ends of the transition steel rod and fixedly connected with the beam body. The telescopic assembly extends in the axial direction of the transition steel rod. The telescopic assembly comprises two connecting rods connected with the two anchoring assemblies in a one-to-one correspondence mode and a telescopic force bearing rod arranged between the two connecting rods. The two ends of the telescopic force bearing rod are limited to the corresponding connecting rods through elastic pieces correspondingly, and the telescopic force bearing rod and the transition steel rod are in sliding connection in the axial direction of the transition steel rod. And the two groups of first strain sensors are symmetrically arranged on the telescopic bearing rod up and down. The self-sensing anti-beam-falling device provided by the invention can adapt to telescopic deformation of the beam body in a normal use state, and can accurately evaluate the safety of the bridge in time.
本发明提供了一种自感知防落梁装置，属于防落梁技术领域，包括过渡钢杆、两组锚固组件、伸缩组件和两组第一应变传感器；过渡钢杆的两端分别设置在相邻的两组梁体上；两组锚固组件对应设于过渡钢杆的两端，且与梁体固定连接；伸缩组件沿过渡钢杆的轴向延伸；伸缩组件包括两个与两组锚固组件一一对应连接的连接杆，和设于两个连接杆之间的伸缩承力杆；伸缩承力杆的两端分别通过弹性件限位在对应的连接杆上，且伸缩承力杆与过渡钢杆沿过渡钢杆的轴向滑动连接；两组第一应变传感器上下对称设于伸缩承力杆上。本发明提供的自感知防落梁装置能适应梁体正常使用状态下的伸缩变形，且可及时准确地对桥梁的安全性进行评估。
