Bulletproof and damping device for inhaul cable
The expansion device for the double-inclined-plane bridge is a bulletproof damping device which is simple in structure and small in occupied expansion joint space and does not need to reserve a control mechanism space. According to the technical scheme, an inhaul cable rotates in a reciprocating mode between a bottom fulcrum of a double-slope cover plate and an expansion joint inner beam end fulcrum or a bottom fulcrum of a V-shaped supporting rod and is kept in a tensioning state, so that slopes on the two sides of the bottom of the double-slope cover plate and a vertex angle slope of the beam end are kept attached and pressed tightly, and the situation that the double-slope cover plate rebounds or moves after a vehicle impacts a load is avoided.
一种用于双斜面桥梁伸缩装置，结构简单，占用伸缩缝空间小，不用预留控制机构空间的防弹减振装置。技术方案是：拉索在双斜面盖板底部支点与伸缩缝内梁端支点或V形撑杆底部支点间往复转绕并保持张紧状态，使双斜面盖板底部两侧的斜面与梁端顶角斜面保持贴合压紧，以避免车辆冲击载荷过后双斜面盖板产生反弹或移位。
