Force transmission type damping energy dissipation concrete structure anti-collision device and anti-collision method
The invention discloses a force transmission type damping energy dissipation concrete structure anti-collision device and an anti-collision method. The anti-collision device comprises a plurality of force transmission type damping energy dissipation units which are distributed in a linear or arc or circular mode, wherein each force transmission type damping energy dissipation unit comprises a collision system, a constraint system, a power conversion system and a bottom plate, each collision system comprises a collision plate, a dowel bar and a pressed damper, each constraint system comprises asleeve, each power conversion system comprises a crank, a rotating shaft, a diagonal draw bar and a tension damper, the position of each rotating shaft is fixed, the crank is sleeved on each rotatingshaft, one end of each rotating shaft is hinged with the dowel bar, the other end of each rotating shaft is hinged with the diagonal draw bar, the middle of each diagonal draw bar is installed with the tension damper, the bottom end of each diagonal draw bar is hinged with the bottom plate, and the bottom plate is installed in a foundation. According to the anti-collision device, horizontal impact force borne by the collision systems is transmitted to the bottom plates through the power conversion systems, pressed damper and tension damper are buffered and absorb energy in the force transmission process, impact energy is finally transmitted to the ground, a concrete structure is protected against the influence of the impact force, and therefore the purpose of protecting the concrete structure is achieved.
本发明公开了一种传力式阻尼耗能混凝土结构防撞装置及防撞方法，包括若干个呈直线型、弧形或圆形布设的传力式阻尼耗能单元；每个传力式阻尼耗能单元均包括碰撞系统、约束系统、动力转换系统和底板；碰撞系统包括碰撞板、传力杆和受压阻尼；约束系统包括套筒，动力转换系统包括曲柄、转轴、斜拉杆和受拉阻尼；转轴位置固定，曲柄套装在转轴上，一端铰接传力杆，另一端铰接斜拉杆；斜拉杆中部安装受拉阻尼，底端铰接底板；底板安装在地基中。本发明通过动力转换系统将碰撞系统受到的水平冲击力传递给底板，传力过程中受压阻尼与受拉阻尼缓冲吸能，最终将冲击能量传给大地，护混凝土结构则不受冲击力的影响，从而达到保护混凝土结构的目的。
