The invention discloses a parallel telescopic bridge. The parallel telescopic bridge comprises a bridge main body fixing part and a parallel telescopic part. The bridge main body fixing part is weldedby a steel structure, a vertical column, base and cross beam cable-stayed fixing mode is adopted, the vertical column is provided with a hydraulic cylinder for driving up-and-down stretching, and thebase is integrally connected with a ground foundation; and the parallel telescopic part adopts a connecting rod structure, the connecting rod structure is provided with a foldable bridge deck, 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 so that the hydraulic cylinder pushes the upper end of the connecting rod structure to shrink the connecting rod structure and shrinkthe folding bridge plate to shrink the telescopic part of the 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 unfold the telescopic part of the bridge. In the using process, the hydraulic cylinder is driven to be unfolded, the parallel telescopic bridge is in a contracted state, and water surface ships and the like are not affected to travel back and forth; and when the hydraulic cylinder is driven to retract, the parallel telescopic bridge is in an unfolded state for pedestrians and vehicles to pass through a bridge surface.
一种可平行伸缩的桥梁。该平行伸缩桥包括：桥梁主体固定部分、平行伸缩部分；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，立柱安装用于驱动上下伸缩的液压缸，底座与地面基础连接为一体；平行伸缩部分采用连杆结构，连杆结构安装有可折叠的桥面板，连杆结构的下端与桥梁立柱链接，连杆结构的上端与液压缸上端链接。其工作原理是：驱动液压缸展开，使液压缸推动连杆结构上端使连杆结构收缩，并同时收缩折叠桥板，达到桥梁伸缩部分的收缩；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伸缩部分的展开。在使用过程中驱动液压缸展开则平行伸缩桥处于收缩状态，此时不影响水面船只等来往行驶；驱动液压缸收回则平行伸缩桥处于展开状态，供行人车辆从桥面上通行。
