The invention discloses a guide pulley device with a lifting steel wire rope pre-tightening function. The guide pulley device comprises a guide pulley arranged on a crane cantilever head, a plurality of pressing rollers are further arranged on the side part of the guide pulley, a lifting steel wire rope is clamped between the pressing rollers and the guide pulley, the guide pulley is connected with a speed reducing mechanism, and the speed reducing mechanism is used for controlling the torque of the guide pulley so as to pre-tighten or release the lifting steel wire rope. According to the guide pulley device with the lifting steel wire rope pre-tightening function, when the lifting steel wire rope is recycled, pre-tightening force can be applied to the lifting steel wire rope, and the problems of rope disorder, layer jumping and crushing of the lifting steel wire rope on a winding drum are solved; and the lifting steel wire rope can be smoothly released by regulating and controlling the speed reducing mechanism, so that the complexity of disassembly and assembly is avoided.

    本发明公开了一种具有预紧起升钢丝绳功能的导向滑轮装置,包括安装于起重机悬臂臂头的导向滑轮,所述导向滑轮的侧部还设置有若干压紧滚轮,所述压紧滚轮和所述导向滑轮之间夹接有起升钢丝绳,所述导向滑轮连接有减速机构,所述减速机构用于控制所述导向滑轮的扭矩,以实现对起升钢丝绳的预紧或释放。本发明采用上述结构的一种具有预紧起升钢丝绳功能的导向滑轮装置,不仅可以在回收起升钢丝绳时,对起升钢丝绳施加一个预紧力,避免起升钢丝绳在卷筒上出现乱绳、跃层和压溃问题,还可以通过调控减速机构,使起升钢丝绳可以顺滑的释放,避免了拆装的繁琐。
