Novel suspension bridge center buckle device
The invention discloses a novel suspension bridge center buckle device which comprises a cable clamp, a sling upper pulley, a double-strand sling, a vibration reduction frame, a sling lower pulley, adouble-strand sling fixing device, a space type inclined rod, a viscous damper and a space type inclined rod fixing device. The cable clamp is fixed to the midspan position of a suspension bridge maincable, and the upper ends of the suspension cable upper pulleys and the upper ends of the inclined rods are fixed to the cable clamp. The double-strand slings form a closed loop through upper and lower pulleys, and a plurality of damping frames are arranged in the middle of the double-strand slings; and the viscous damper is fixed in the middle of the inclined rod. The sling forms a closed loop through the upper pulley and the lower pulley, the vibration reduction frame is arranged, and the viscous damper is arranged on the inclined rod, so that longitudinal vibration of the short sling is reduced, and damage to an anchor head of the sling due to longitudinal reciprocating motion is prevented; by arranging the space type inclined rods, transverse vibration of the short slings is reduced.The device can be arranged in the midspan of the suspension bridge and used for multi-directional damping of the midspan short slings.
本发明公开了一种新型悬索桥中央扣装置，包括索夹、吊索上滑轮、双股吊索、减振架、吊索下滑轮、双股吊索固定装置、空间型斜杆、粘滞阻尼器以及空间型斜杆固定装置；所述索夹固定于悬索桥主缆跨中部位，所述吊索上滑轮、斜杆上端固定于索夹；所述双股吊索通过上下滑轮形成闭环，中部设若干减振架；所述粘滞阻尼器固定于斜杆中部。本发明通过将吊索通过上下滑轮形成闭环、设置减振架、在斜杆上设粘滞阻尼器，减小了短吊索纵向振动，防止由于纵向往复运动导致吊索锚头损坏；本发明通过设置空间型斜杆，减小了短吊索横向振动。本发明可设置于悬索桥跨中，用于跨中短吊索的多向减振。
