Bridge section unfolding and folding mechanism and unfolding and folding method
The invention discloses a bridge section unfolding and folding mechanism and an unfolding and folding method. The bridge section unfolding and folding mechanism comprises an actuator I, a three-hole swing block and an actuator II. Hinge shaft holes in the three-hole swing block are distributed in a T shape, the three-hole swing block is hinged to one end of the actuator I and one end of the actuator II through the two hinge shaft holes distributed in the horizontal direction respectively, and the three-hole swing block is hinged to the sharp boat and the ark through the other hinge shaft hole at the same time. The other end of the actuator I and the other end of the actuator II are hinged to the sharp boat and the ark correspondingly, and the sharp boat is driven by the actuator I and the actuator II to rotate by 90 degrees so that the sharp boat can be folded above the ark. A containing unfolding and folding mechanism does not need to be arranged, unfolding is stable, and pontoon bridge connection is reliable.
本发明公开了一种桥节展收机构及展收方法，包括执行器Ⅰ、三孔摆块及执行器Ⅱ；三孔摆块上的铰轴孔呈T型分布，所述三孔摆块通过水平方向分布的两个铰轴孔分别与所述执行器Ⅰ、执行器Ⅱ一端铰接，三孔摆块通过剩余的一个铰轴孔同时与尖舟、方舟铰接；执行器Ⅰ、执行器Ⅱ另一端分别与尖舟、方舟铰接，通过执行器Ⅰ、执行器Ⅱ分别带动尖舟转动90°实现其折叠在方舟上方。本发明无需开设容纳展收机构，展开平稳、舟桥连接可靠。
