Steel truss girder large cantilever remote control rapid carrying hole-passing method and steel truss girder large cantilever remote control rapid carrying hole-passing device
The invention provides a remote control rapid carrying hole passing method and device for a large cantilever of a steel truss girder. The device comprises a first station, a second station and a third station. A plurality of three-dimensional hydraulic remote control power piggy-back trolleys are arranged at the first station to support the steel truss girder and provide driving force for rapid walking of the steel truss girder; continuous jacks and steel strands are arranged on the two sides of the steel truss girder to pull the steel truss girder to rapidly walk in the first direction; a sliding shoe and a vertical oil jack are arranged on the second station, the sliding shoe is supported on a node of the steel truss girder, and the large cantilever for supporting the steel truss girder slides forwards by one steel truss girder inter-node distance every time; a vertical oil jack and an automatic guide tank roller transporter are arranged on the third station, and the automatic guide tank roller transporter carries the perforated steel truss girder to continuously roll and walk forwards; the heavy-load frictional resistance is reduced through carrying and rolling, and a single sliding shoe plays a role in braking when walking stops; through remote control operation, the whole-hole steel truss girder is linearly, safely, stably, synchronously, continuously and rapidly carried along a track through a hole in a small-resistance, small-stroke and full-stroke mode through a large cantilever.
本发明提出了一种钢桁梁大悬臂遥控快速驮运过孔方法及装置，包括第一、第二、第三工位。在第一工位设置多台三维液压遥控动力驮运台车支撑钢桁梁，并为钢桁梁快速行走提供驱动力；在钢桁梁两侧设置连续千斤顶及钢绞线牵引钢桁梁沿第一方向快速行走；在第二工位上设置滑靴和垂直油顶，滑靴支承在钢桁梁的节点上，每次支撑钢桁梁大悬臂向前滑移一个钢桁梁节间距离；在第三工位上设置垂直油顶和自动导向坦克滚轴移运器，自动导向坦克滚轴移运器驮运已过孔钢桁梁继续向前滚动行走；驮运及滚动减少了重载摩擦阻力、单个滑靴在行走停止时起到制动作用；遥控操作，将整孔钢桁梁沿轨道直线、小阻力、安全、平稳、同步、连续、全行程大悬臂快速驮运过孔。
