Anti-seismic device for highway bridge
The anti-seismic device for the highway bridge comprises a supporting column, a supporting plate is fixedly connected to the top of the supporting column, a shock pad mechanism is fixedly arranged on the top face of the supporting plate, an anti-seismic plate is fixedly connected to the top face of the shock pad mechanism, and grooves are formed in the two sides of the top face of the anti-seismic plate correspondingly; and a sleeve rod is fixedly connected to the interior of the groove, buffer springs symmetrically sleeve the two ends of the sleeve rod, a buffer mechanism is fixedly connected to one side of each buffer spring, and an anti-seismic mechanism is fixedly connected to the middle of the top face of the anti-seismic plate. According to the device, through the arrangement of the damping mechanism and the buffering mechanism, when the bridge plate is vibrated, a hydraulic rod and an anti-vibration spring synchronously deform, vibration force is subjected to preliminary damping, a buffering rod rotates due to vibration and extrudes a buffering spring, so that the buffering spring stretches out and draws back on the surface of a sleeve rod, the vibration force is buffered, the bridge plate is more stable, and damage caused by vibration is avoided.
本发明公开了一种公路桥梁用抗震装置，包括支撑柱，所述支撑柱的顶部固定连接有支撑板，所述支撑板的顶面固定设置有减震垫机构，所述减震垫机构的顶面固定连接有抗震板，所述抗震板顶面的两侧均开设有凹槽，所述凹槽的内部的固定连接有套杆，所述套杆的两端对称套接有缓冲弹簧，所述缓冲弹簧的一侧固定连接有缓冲机构，所述抗震板顶面的中部固定连接有抗震机构。本发明中，通过减震机构和缓冲机构的设置，桥梁板受到振动时，液压杆和抗震弹簧同步产生形变，将振动力进行初步减震，缓冲杆因振动发生转动，挤压缓冲弹簧，使其在套杆表面伸缩，将振动力进行缓冲，使得桥梁板更加稳定，避免因振动受损。
