The invention discloses an anti-seismic and anti-beam-falling device for a bridge. A first supporting column body moves up and down under the action of an elastic buffer pad, and an elastic rubber layer on the surface of a movable block rubs with an annular buffer bulge on the inner wall of a hollow column body, so that the up-down moving amplitude of the first supporting column body is reduced, and further the vibration force in the vertical direction caused by earthquake can be weakened gradually; a first spring gradually weakens vibration force in different horizontal directions, balls arearranged on the first curved surface and the second curved surface, so that the seismic force in the vertical direction is also consumed and weakened, and the anti-seismic effect is further enhanced;a second supporting column body, a supporting block, a left beam body and a right beam body are fixed together through a clamping groove and a steel cable, meanwhile, the steel cable has pulling forcein the vertical direction and the horizontal direction to fix the second supporting column body, the left beam body and the right beam body, the left beam body and the right beam body are prevented from falling off, and the anti-seismic and anti-beam-falling effects are achieved.
本发明公开了一种桥梁抗震防落梁装置，通过第一支撑柱体在弹性缓冲垫的作用下上下移动，活动块表面的弹性橡胶层与空心柱体内壁上的环形缓冲凸起摩擦，从而使第一支撑柱体上下移动的幅度减小，从而达到逐渐消耗减弱地震带来的竖直方向上的震力，通过第一弹簧将水平方向上各个方向的震力逐渐消耗减弱，同时由于滚珠设置在第一曲面和第二曲面，因此，在竖直方向上也会对震力进行消耗减弱，进一步加强抗震效果，卡槽和钢索将第二支撑柱体、支撑块、左梁体和右梁体固定在一起，同时钢索在竖直方向和水平方向上均有一个拉力，对第二支撑柱体、左梁体和右梁体进行固定作用，防止左梁体和右梁体掉落，起到抗震防落梁的效果。
