The invention discloses a folding telescopic bridge. The folding telescopic bridge comprises a bridge main body fixing part and a folding telescopic part. The bridge main body fixing part is formed bywelding a steel structure and adopts a fixing mode of obliquely pulling a stand column, a base and a cross beam, the stand column is provided with a hydraulic cylinder used for driving the stand column to stretch up and down, the hydraulic cylinder adopts a semi-underground installation mode, and the base is connected with a concrete foundation into a whole body; and the folding telescopic part adopts a connecting rod structure, a folding bridge plate is installed on the connecting rod structure, a lower end of the connecting rod structure is connected with a bridge stand column, and the upper end of the connecting rod structure is connected with the upper end of the hydraulic cylinder. A working principle comprises that the hydraulic cylinder is driven to unfold, and the hydraulic cylinder pushes the upper end of the connecting rod structure to shrink the connecting rod structure, and drives a folding bridge plate to fold and shrink a bridge; and the hydraulic cylinder is driven to retract, the hydraulic cylinder drives the upper end of the connecting rod structure to unfold the connecting rod structure, and meanwhile the folding bridge plate is unfolded to achieve expansion of bridge folding and stretching. In a using process, the hydraulic cylinder is driven to be unfolded, the folding telescopic bridge is in a contracted state, and water surface ships and the like are notinfluenced to travel back and forth; and when the hydraulic cylinder is driven to retract, the folding telescopic bridge is in an unfolded state for pedestrians and vehicles to pass through a bridge surface.
一种可折叠伸缩的桥梁。该折叠伸缩桥包括：桥梁主体固定部分、折叠伸缩部分，所述桥梁主体固定部分由钢结构焊接，采用立柱、底座加横梁斜拉的固定方式，所述的立柱安装用于驱动上下伸缩的液压缸，所述的液压缸采用半地面下安装的方式，所述的底座与混凝土基础连接为一体；所述的折叠伸缩部分采用连杆结构，所述的连杆结构安装有折叠桥板，所述的连杆结构的下端与桥梁立柱链接，所述的连杆结构的上端与液压缸上端链接。工作原理是：驱动液压缸展开，液压缸推动连杆结构上端使连杆结构收缩，并同时带动折叠桥板达到桥梁折叠收缩；驱动液压缸收回，液压缸带动连杆结构上端使连杆结构展开，并同时展开折叠桥板达到桥梁折叠伸缩的展开。在使用过程中驱动液压缸展开则折叠伸缩桥处于收缩状态，此时不影响水面船只等来往行驶；驱动液压缸收回则折叠伸缩桥处于展开状态，供行人车辆从桥面上通行。
