Method for erecting bridge span through mechanical bridge erecting vehicle
The embodiment of the invention provides a method for erecting a bridge span by a mechanical bridge erecting vehicle, which comprises the following steps: enabling the tail of the bridge erecting vehicle to face an area to be spanned, and bearing the bridge span on a bridge erecting vehicle body of the mechanical bridge erecting vehicle; a front swing frame is controlled to swing to the highest position, so that a first bridge section, located on the upper portion, in the bridge span is lifted at the end of the vehicle head side; a push-out structure arranged on the movable frame is controlled to push out the movable frame and the second bridge section towards the vehicle tail side; after the first bridge section is pushed out, hydraulic supporting legs of the movable frame are controlled to stretch out to be supported on the ground, and an erecting oil cylinder on the movable frame is controlled to lift the other end of the first bridge section; the second bridge section is driven by the bridge pushing mechanism to move towards the vehicle tail side, and the first bridge section is lowered to the bridge erecting vehicle body; controlling the bridge pushing mechanism to drive the second bridge section to move towards the first bridge section, and connecting and fixing; the axle pushing mechanism is controlled to drive the axle span to move towards the tail side of the vehicle, a reverse oil cylinder of the erecting frame assembly is controlled to stretch out, the erecting frame assembly is pushed to rotate reversely, and the axle span falls down.
本发明实施例提供了一种机械化架桥车架设桥跨的方法，包括将架桥车车尾正对待跨越区域，机械化架桥车的架桥车本体上承载有桥跨；控制设于前摆架上摆至最高位置，使桥跨中处于上部的第一节桥节在车头侧的端部被举升；控制设于移动架推出结构将移动架连同第二节桥节向车尾侧推出；在被推出后，控制移动架的液压支腿伸出支撑在地面上，控制移动架上的架设油缸将第一节桥节的另一端举升；通过推桥机构驱动第二节桥节向车尾侧移动，将第一节桥节下放至架桥车本体上；控制推桥机构驱动第二节桥节向第一节桥节移动，连接固定；控制推桥机构驱动桥跨向车尾侧移动，控制架设架总成的反转油缸伸出，推动架设架总成反转，将桥跨落下。
