Auxiliary folding and unfolding device for impact bridge erection
The invention provides an auxiliary folding and unfolding device for impact bridge erection, and belongs to the technical field of impact bridge erection. The auxiliary folding and unfolding device for impact bridge erection comprises an erection assembly and an auxiliary folding and unfolding assembly. The erecting assembly comprises an erecting vehicle, an erecting mechanism, a winch and a guide wheel. The lower portion of the erecting mechanism and the impact bridge are tensioned by four strands, the single-cantilever stress state of the erecting mechanism before driving the impact bridge to the ground is improved, stress of a driving element on the erecting mechanism is reduced, the situation that the impact bridge is erected to the ground in the related technology is effectively improved, and the erecting mechanism supports the impact bridge in a cantilever mode; the problems that when two impact bridges are combined and the weight is increased, supporting force is provided for the two combined impact bridges, the stress at the position of the erecting mechanism is improved, and the laying operation can be normally completed are solved by solving the problems that in the prior art, the stress condition of the erecting mechanism is inconvenient to improve, the driving force of a driving oil cylinder used for erecting is insufficient, and the laying danger is increased.
本发明提供了一种冲击桥架设用辅助收放装置，属于冲击桥架设技术领域。该冲击桥架设用辅助收放装置包括架设组件和辅助收放组件。所述架设组件包括架设车、架设机构、绞盘和导向轮。由四股拉紧拉住架设机构的下部和冲击桥，改善架设机构带动冲击桥至落地前呈单悬臂的受力状态，减少架设机构上驱动元件的受力，进而有效改善相关技术中冲击桥的架设至落地前，架设机构呈悬臂式支撑住冲击桥，不便于改善架设机构的受力情况，进而容易导致架设使用驱动油缸的驱动力不足，使铺设的危险性增加的问题，两个冲击桥联合后，重量增加的情况下，为两个联合后冲击桥提供支撑力，改善架设机构处的受力，使铺设作业可正常的完成。
