Novel energy-saving self-balancing vertical lifting type movable bridge
A disclosed novel energy-saving self-balancing vertical lifting type movable bridge comprises an opening span, a lifting tower, a bearing sling and a driving rotary drum, self-balancing side spans are arranged in the outer sides of the lifting tower respectively, the bearing sling bypasses the driving rotary drum and then is connected with the ends, close to the lifting tower, of the self-balancing side spans, and the ends of the self-balancing side spans form vertical movable ends; and the other end of each self-balancing side span is hinged with the fixed part to form a connecting structure capable of rotating up and down, so that the vertical movable end of the self-balancing side span is adjacent to the opening span. By means of the structural self-weight of the rotatable self-balancing side spans and the additional balance weight arranged in the self-balancing side spans, the vertical gravity of the self-balancing side spans at one side of the lifting tower is approximately equal to the vertical gravity of one end of the opening span, so that the balance weight arranged in the lifting tower is completely omitted, the applicable span of the vertical lifting type movable bridge is expanded, and the energy consumption of opening and closing operation can be reduced.
本发明公开了一种新型节能自平衡直升式开启桥，包括有开启跨、提升塔、承重吊索和驱动转筒，在提升塔的外侧各设有自平衡边跨，承重吊索绕过驱动转筒后与自平衡边跨靠近提升塔的一端连接，使自平衡边跨的该端形成竖向活动端，自平衡边跨的另一端与固定部位采用铰接连接形成可上下转动的连接结构，使自平衡边跨的竖向活动端与开启跨毗邻。本发明利用能转动的自平衡边跨的结构自重与在其内布置额外配重，使得自平衡边跨在提升塔一侧的竖向重力能与开启跨一端的竖向重力大致相等，从而实现完全取消在提升塔内布置配重，扩展直升式开启桥的适用跨径，还能降低启闭运行的能耗。
