Ballast type damper with limiting cable and mounting method thereof
The invention discloses a weight type damper with a limiting cable and an installation method thereof.The damper comprises a weight box, a spring, the limiting cable, a main beam bottom plate and a transverse partition stop dog, the spring is vertically arranged, the two ends of the spring are fixed to the weight box and the main beam bottom plate respectively to form a tuned mass damper, one end of the limiting cable is fixed to the weight box, and the other end of the limiting cable is fixed to the transverse partition stop dog; one end of the limiting cable is fixed to a main beam bottom plate, the other end of the limiting cable is fixed to a main beam bottom plate, the limiting cable is tensioned to the designed initial tension, the spring is compressed to the designed required length, ballasting filler is placed in the ballasting box, an additional mass block of the hardening and tempering mass damper is formed, the tension borne by the limiting cable in the daily operation state is smaller than the ultimate strength of the limiting cable, and the damper restrains vibration generated by a vehicle. When an earthquake or strong wind occurs, the tensile force borne by the limiting cable is larger than the ultimate strength of the limiting cable, the limiting cable is broken and unloaded, the damper relieves limitation, vibration generated by the earthquake is restrained, and the problem that an existing tuned mass damper cannot meet the requirements for restraining vehicle-induced vibration and multi-stage earthquake fortification is solved.
本发明公开了一种带限位索的压重式阻尼器及其安装方法，阻尼器包括压重箱、弹簧、限位索、主梁底板和横隔挡块，弹簧竖直设置，其两端分别固定于压重箱和主梁底板上形成调谐质量阻尼器，限位索一端固定于压重箱，另一端固定于主梁底板，将限位索张拉至设计初的张力，使弹簧压缩至设计所需长度，压重箱内放置压重填充物，构成调质质量阻尼器的附加质量块，日常运营状态下限位索受到的拉力小于其极限强度，阻尼器抑制车辆产生的振动，发生地震或强风状况时限位索受到的拉力大于其极限强度，限位索断裂卸载，阻尼器解除限制，抑制地震产生的振动，解决了现有的调谐质量阻尼器难以满足抑制车致振动及多级抗震设防需求的问题。
