Herringbone bridge foot foundation plate assembly folding and unfolding mechanism
The invention discloses a herringbone bridge foot foundation plate assembly folding and unfolding mechanism. The mechanism comprises a winch, a steel wire rope, a torsion bar and a pulley assembly. The winch is installed on the side edge of a bridge structure, one end of the steel wire rope is connected with the winch, and the other end is fixed to an upper column away from the bridge structure after bypassing the pulley assembly. The herringbone bridge foot comprises two upper columns, one ends of the two upper columns are hinged to the bridge structure, the torsion bar is installed between the two upper columns, the other ends of the two upper columns are hinged to the two ends of a foundation plate assembly through spherical hinges respectively, and the foundation plate assembly is foldable; when the winch tightens the steel wire rope, the pulley assembly is pulled to move towards the end where the torsion bar of the herringbone bridge is located, the foundation plate assembly is driven to be folded, and meanwhile the torsion bar is compressed to store energy; and when the winch loosens the steel wire rope, the torsion bar releases the stored energy to push the foundation plateassembly to unfold and drive the herringbone bridge foot to unfold.
本发明公开了一种人字形桥脚础板组件折展机构，包括：绞盘、钢丝绳、扭力杆和滑轮组件；所述绞盘安装在桥梁结构的侧边，钢丝绳一端与绞盘连接，另一端绕过滑轮组件后固定在远离桥梁结构的上柱上；其中，人字形桥脚包括：两个上柱，两个上柱一端铰接在桥梁结构上，并在两个上柱之间安装有扭力杆，另一端分别与础板组件的两端通过球铰铰接；其中，础板组件可折叠；所述础板组件的中部与滑轮组件铰接，当绞盘收紧钢丝绳时，拉动滑轮组件向人字形桥的扭力杆所在端移动，带动础板组件折叠，同时扭力杆压缩储能；当绞盘松开钢丝绳时，扭力杆释放储能，推动础板组件展开，带动人字形桥脚展开。
