Steel truss girder node following type walking type pushing system
The invention provides a steel truss girder node following type walking type pushing system which comprises pushing equipment, an upper supporting mechanism and a retreating device. The construction steps comprise an initialization stage, a jacking stage, a transverse moving stage, a falling-back stage, a forward moving stage, a stage of approaching a beam falling support, a stage of falling a steel truss on the beam falling support, a to-be-reset stage and a full-reset stage. Through combined application of the upper supporting mechanism and the pushing equipment, it is guaranteed that the stress points of the steel truss girder are located at the same node position all the time; through the design of the upper supporting mechanism and the roller device, the counter-force resistance in the pushing forward stage is reduced, and the construction efficiency in the forward stage is improved; through the beam falling base plate, the rolling wheel device, the rolling wheel base plate and the rollback device, rapid resetting of the pushing equipment, the upper supporting mechanism and the rolling wheel device is achieved, operation is easy, the control difficulty is low, and the efficiency of walking type pushing construction of the steel truss beam is greatly improved.
本发明提供一种钢桁梁节点跟随式步履式顶推系统，所述系统包括：顶推设备、上部支撑机构和回退装置，所述施工步骤包括：初始化阶段、顶升阶段、横移阶段、回落阶段、前行阶段、临近落梁支座阶段、钢桁梁落于落梁支座阶段、待复位阶段和全复位阶段；通过对上部支撑机构与顶推设备的组合运用，保证了钢桁梁的受力点始终于同一节点位置；通过对上部支撑机构和滚轮装置的设计，减少了顶推前行阶段的反力阻力，增加了前行阶段的施工效率；通过落梁垫板、滚轮装置、滚轮垫板和回退装置，实现了顶推设备、上部支撑机构和滚轮装置的快速复位，并且操作简单，控制难度低，大幅度提升了钢桁梁步履式顶推施工的效率。
