Beam falling prevention device capable of preventing transverse deviation
The invention relates to the technical field of bridges and discloses a beam falling prevention device capable of preventing transverse deviation. The device comprises a main beam, a bridge pier usedfor supporting the main beam and rotary energy dissipation devices arranged between the main beam and the bridge pier; an arc-shaped protrusion is arranged at the bottom of the main beam; an annular groove is formed in the upper end of the bridge pier; the protrusion is in sliding fit with the annular groove; the multiple sets of rotary energy dissipation devices are sequentially connected from head to tail along the outer side of an annular guide rail; and the sliding blocks of each set of rotary energy dissipation devices are in sliding fit with the annular guide rail. The beam falling prevention device is used for being installed between the bridge pier and a bridge; energy consumption is limited for the arc-shaped displacement of the main beam, so that overlarge displacement in the bridge in a transverse direction is prevented; and the effects of shock absorption, energy consumption and beam falling prevention of the bridge under the action of earthquakes are achieved.
本发明涉及桥梁技术领域，具体公开了一种防止横向偏移的防落梁装置，包括主梁、用于支撑所述主梁的桥墩以及设置在所述主梁和桥墩之间的旋转耗能装置，所述主梁的底部设置有弧形的凸起，所述桥墩的上端开设有环槽，所述凸起与所述环槽滑动配合；所述旋转耗能装置为若干组，旋转耗能装置沿所述环形导轨的外侧从头到尾依次连接，每一组旋转耗能装置的滑块与所述环形导轨之间滑动配合。本发明装置用于安装在桥墩和桥梁之间，通过对主梁弧形位移的一个限制耗能，从而防止桥梁之间在横向发生过大的位移，解决在地震作用下桥梁减震耗能防落梁的作用。
