Multistage anti-impact and anti-collision device
The invention belongs to the technical field of anti-collision and vibration reduction, and particularly relates to a multi-stage anti-impact and anti-collision device. The device comprises an outer buffer sleeve, an extrusion friction energy absorber, a fender, an electromagnetic damper, a pier outer sleeve and an elastic damper, the bridge pier outer sleeve sleeves the periphery of the bridge pier and can slide along the bridge pier; the fender sleeves the periphery of the pier outer sleeve; one end of the electromagnetic damper is connected with the pier outer sleeve, and the other end of the electromagnetic damper is connected with the inner side surface of the fender; one end of the elastic damper is connected with the pier outer sleeve, and the other end of the elastic damper is connected with the inner side surface of the fender; the outer-layer buffer sleeve is sleeved on the periphery of the fender; one end of the extrusion friction energy absorber is connected with the outer side face of the fender, and the other end of the extrusion friction energy absorber is connected with the inner side face of the outer-layer buffering sleeve. The bridge pier is subjected to collision prevention and vibration reduction through three-stage energy absorption, and the collision resistance can be greatly improved.
本发明属于防撞减振技术领域，具体涉及一种多级抗冲防撞装置。该装置包括外层缓冲套、挤压摩擦吸能器、护舷、电磁阻尼器、桥墩外套筒和弹性阻尼器；桥墩外套筒套设在桥墩外围，能够沿桥墩滑动；护舷套设在桥墩外套筒外围；电磁阻尼器围绕桥墩设置，一端与桥墩外套筒连接，另一端与护舷的内侧面连接；弹性阻尼器围绕桥墩外套筒设置，一端与桥墩外套筒连接，另一端与护舷的内侧面连接；外层缓冲套套设在护舷外围；挤压摩擦吸能器围绕护舷设置，一端与护舷外侧面连接，另一端与外层缓冲套的内侧面连接。本发明采用三级阶段式吸能对桥墩进行防撞减振，能大幅度增加抗撞性能。
