Rail bridge seismic mitigation and isolation device with pressure monitoring function
The invention discloses a rail bridge seismic mitigation and isolation device with a pressure monitoring function. The device comprises a seismic isolation support core body, an upper support plate, a lower support plate and a limiting detection device, and the limiting detection device comprises an upper mounting base, a limiting detector and a limiting column; the limiting detection device comprises a shell, a sliding block, a piston rod, a piston and a fixing sleeve, an oil pressing cavity, an oil outlet cavity, an oil storage cavity and a pressure sensor are arranged in the shell, an oil pressing hole is formed in the lower portion of the piston, a spring is arranged between the fixing sleeve and the sliding block, and the limiting column extends into the shell and is in inclined plane connection with the sliding block; the limiting detector and the limiting column are arranged, the limiting column moves up and down to drive the sliding block to move horizontally, the impact of the limiting column on the sliding block is reduced through a spring and a hydraulic damping shock absorption oil way, the impact of beam body vibration on the shock insulation support core body is reduced, and the stress condition of the bridge shock absorption and insulation support is monitored in real time through a pressure sensor in the oil way, shear deformation and failure of the support are avoided, and the anti-seismic and anti-pressure capability of the support is improved.
本发明公开了一种带有压力监控的轨道桥梁减隔震装置，包括隔震支座芯体、上支座板、下支座板和限位检测装置，限位检测装置包括上安装座、限位检测器和限位柱；限位检测装置包括壳体、滑块、活塞杆，活塞和固定套，所述壳体内设置有压油腔、出油腔、储油腔和压力传感器，活塞下部设置有压油孔，固定套和滑块之间设有弹簧，限位柱延伸至壳体内与滑块之间斜面连接；本发明通过设有限位检测器和限位柱，限位柱上下移动驱动滑块水平移动，采用弹簧和液压阻尼减震油路减少限位柱对滑块冲击，达到减少梁体震动对隔震支座芯体的冲击，通过油路中的压力传感器实时监测桥梁减隔震支座受力情况，避免支座剪切变形失效，提高支座抗震抗压能力。
