Self-locking resettable energy-dissipation multidirectional limiting bridge anti-seismic device
The invention discloses a self-locking resettable energy-dissipation multidirectional limiting bridge anti-seismic device which comprises a steel corbel, a friction limiting top plate, a transmissionlimiting steel column, a transmission sliding block, a friction limiting sliding block, a support check block, a transmission plate, a first steel spring and a second steel spring. The steel corbel isfixed to the side wall of the pier through bolts. The friction limiting top plate is fixed to the bottom of the bridge girder through bolts, one end of the transmission limiting steel column is connected with the bottom of the friction limiting top plate through a spherical hinge support, and the other end of the transmission limiting steel column is connected to a first protruding block of the transmission sliding block through a spherical hinge support. The transmission sliding block is connected to the bottom of the support check block through a first steel spring. The friction limiting sliding block is connected to the upper portion of the support check block through a first steel spring. The two ends of the transmission plate are fixedly connected with second steel springs and connected with the support check blocks through hinge supports. The self-locking resettable energy-dissipation multidirectional limiting bridge anti-seismic device can achieve a good self-locking effect while limiting a bridge, and is good in overall energy dissipation and shock absorption effect, simple and reasonable in structure and convenient to manufacture.
本发明公开了一种自锁型可复位耗能多向限位桥梁抗震装置，包括钢牛腿、摩擦限位顶板、传动限位钢柱、传动滑块、摩擦限位滑块、支架挡块、传动板、第一钢弹簧和第二钢弹簧；所述钢牛腿通过螺栓固定在桥墩侧壁上；所述摩擦限位顶板通过螺栓固定在桥主梁底部，所述传动限位钢柱一端通过球铰支座与摩擦限位顶板底部连接，另一端通过球铰支座连接在传动滑块的第一突出块上；所述传动滑块通过第一钢弹簧连接在支架挡块底部；所述摩擦限位滑块通过第一钢弹簧连接在支架挡块上部；所述传动板两端固定连接第二钢弹簧，通过铰支座与支架挡块连接。本发明在对桥梁进行限位的同时，能达到良好的自锁效果，装置整体耗能减震效果好，结构简单合理，便于制作。
