Vibration reduction auxiliary cable device for cable-stayed bridge and cable-stayed bridge
The vibration reduction auxiliary cable device for the cable-stayed bridge and the cable-stayed bridge are characterized in that cable-stayed main cables are connected through vibration reduction auxiliary cable assemblies, the two ends of the outer side wall of a lock sleeve are fixedly sleeved with hoops, and the left sides and the right sides of the hoops are connected with vibration reduction assemblies; guiding cylinders are fixed to the left side wall and the right side wall of an inner cavity of the vibration reduction assembly correspondingly, a limiting pull rod is assembled between the two movable plates in a penetrating and penetrating mode, a first traction rope is fixedly connected to the middles of the sides, away from each other, of the two movable plates, and the other end of the first traction rope penetrates through a vibration absorber and extends out of the vibration reduction assembly to be fixedly provided with a first lock catch. The tension degree between the first pulling ropes can be effectively adjusted, so that adjustment of the tension degree of the vibration reduction auxiliary cable assembly is completed, the vibration reduction auxiliary cable assembly can conveniently achieve the pre-tensioning effect on the cable-stayed main cable, vibration of the cable-stayed main cable caused by various kinds of external excitation can be effectively restrained, and the buffering and absorbing effect of the cable-stayed bridge on impact is improved.
本发明公开了一种用于斜拉桥的减振辅助索装置及斜拉桥，所述斜拉主索之间均通过减振辅助索组件连接，所述锁套的外侧壁两端固定套设装配有抱箍，所述抱箍左右两侧均连接装配有减振组件，所述减振组件内腔左右侧壁上均固定有导向筒，且两组所述活动板之间穿插装配有限位拉杆，两组所述活动板的相背离一侧中间固定连接有第一牵引绳，所述第一牵引绳的另一端穿过减振器并延伸出减振组件固定装配有第一锁扣，能够有效调整第一牵引绳之间的张紧度，从而完成对减振辅助索组件的张紧度的调整，便于减振辅助索组件对斜拉主索的预张紧作用，可有效抑制斜拉主索在各种外界激励下所导致的振动，提高斜拉桥对于冲击的缓冲和吸收作用。
