The invention relates to a method for efficiently pulling back a super-long hoisting steel wire rope of a crawler crane, which comprises the following steps of: during the assembly period of the crawler crane, assembling a pin hole space of an original hook head pulley block by utilizing a main arm head, matching with a tool of a reversing roller device, and utilizing reversing and supporting functions of the steel wire rope reversing roller device and traction force within an auxiliary hoisting rated load; and the position of a hook head pulley block of the main arm head is guided by the main lifting winch. Then, a variable-amplitude fly jib rear mast and a variable-amplitude fly jib front mast are installed, the variable-amplitude fly jib rear mast and the variable-amplitude fly jib front mast are integrally hoisted and installed at the tail of a lower section jib of the variable-amplitude fly jib through an auxiliary crane, and then an auxiliary winding steel wire rope is wound on a pulley block of the variable-amplitude fly jib rear mast and the variable-amplitude fly jib front mast in the opposite direction of a rope winding diagram; and the auxiliary variable-amplitude winding steel wire rope is guided to a guide pulley of a specified auxiliary arm head by recovering the auxiliary winding steel wire rope. The long-distance steel wire rope can be dragged to effectively move and wind.

    一种高效回拉履带起重机超长卷扬钢丝绳方法,本发明是在组装履带吊车期间,利用主臂臂头装原配钩头滑轮组销孔空间,配合换向滚筒装置的工装使用,利用钢丝绳换向滚筒装置的换向、支撑功能,以及辅助卷扬额定载荷内的牵引力,将主提升卷扬导引主臂臂头的钩头滑轮组位置。然后安装变幅副臂后桅杆和变幅副臂前桅杆,使用辅助起重机将变幅副臂后桅杆与变幅副臂前桅杆整体吊起安装在变幅副臂下节臂尾部,紧接着将辅助卷扬钢丝绳按缠绳图逆方向缠绕在变幅副臂后桅杆与变幅副臂前桅杆滑轮组,通过回收辅助卷扬钢丝绳将副变幅卷扬钢丝绳导引到指定的副臂臂头的导向滑轮上。本发明实现了可以拖拽长距离钢丝绳有效移动和缠绕的问题。
