Anti-overturning active adjusting device for single-column pier bridge under extreme load
The invention relates to an anti-overturning active adjusting device for a single-column pier bridge under an extreme load, belonging to the field of anti-overturning control for bridges. The anti-overturning active adjusting device comprises a sliding device and a distribution box arranged on the lower portion of a single-column pier body, wherein the top of the single-column pier body supports a main beam through a support; the sliding device is fixed to the inner bottom of the main beam of the single-column pier bridge; the sliding device and the main beam are anchored into a whole; and the sliding device comprises automatic winches, a sliding way and a sliding block. Under the action of the extreme load, an automatic switch is controlled through an inclinometer, the automatic switch is connected with the left automatic winch and the right automatic winch, and a steel strand drives the sliding block to move leftwards and rightwards so as to control overturning deformation of the single-column pier bridge to be within a reasonable range; and after the extreme load disappears, the automatic switch is connected with the left automatic winch so as to achieve a resetting effect. The device of the invention is simple in structure and low in cost, does not affect the attractiveness of the bridge, occupies no space under the bridge, and greatly improves the anti-overturning capacity of the single-column pier bridge.
本发明涉及一种极端荷载下的独柱墩桥梁抗倾覆主动调节装置，属于桥梁抗倾覆控制领域。包括滑动装置以及设置在独柱墩本体下部的配电箱，独柱墩本体顶部通过支座支撑主梁，所述滑动装置固定在独柱墩桥梁的主梁内底部，并与主梁锚固为一体，包括自动卷扬机、滑道以及滑动块。在极端荷载作用下，通过倾角仪来控制自动开关，自动开关接通左、右侧自动卷扬机，通过钢绞线带动滑动块向左、右侧移动，以控制独柱墩桥梁的倾覆变形处于合理范围内，当极端荷载消失后，自动开关接通左侧自动卷扬机以达到复位的效果；本发明结构简单，成本低，不影响桥梁美观，不占用桥下空间，还可以大大提高独柱墩桥梁的抗倾覆能力。
