The invention discloses a quick replacement method for a gantry crane hook beam steel rope. The quick replacement method comprises the following steps that a gantry crane hook beam is horizontally placed on the ground, and a steel rope body is made to be in a loose state; a steel rope pressing plate bolt on one side of a winding drum is dismounted, and a rope head is tied to the ground; a sectionof the head part of an old steel rope body tied to the ground is cut off, and the rope head of the new steel rope body is connected to the rope head of the old steel rope body from the winding drum ina welding mode; the new steel rope body is completely pulled into a movable pulley block and a fixed pulley block, when the new steel rope body is wound around the other side of the winding drum by 3-5 circles; the new steel rope body at a rope outlet hole is hoisted, the winding drum is descended, and the new-old steel rope joint is cut off; the winding drum is rotated to descend, all the old steel rope body is tied to the ground, and the steel rope pressing plate bolt on the other side of the winding drum is removed; and two rope heads of the new steel rope body are correspondingly mountedon the steel rope pressing plate bolts on the two sides of the winding drum. According to the quick replacement method for the gantry crane hook beam steel rope, manpower is saved, the maintenance automation level of a crane is improved, a plurality of steel rope bodies can be updated simultaneously, the maintenance operation speed is high, and reliable connection of the new and old steel rope bodies are achieved.

    一种龙门吊钩梁钢绳的快速更换方法,包括:将龙门吊钩梁水平放置至地面,使钢绳处于松弛状态;将卷筒上的一侧钢绳压板螺栓拆除,绳头系至地面;将系至地面的旧钢绳的头部割掉一段,将新钢绳绳头与卷筒上下来的旧钢绳绳头焊接;将新钢绳全部牵引到动滑轮组和定滑轮组中,待新钢绳缠入卷筒另一侧3‑5圈;将出绳孔处的新钢绳吊起,下降卷筒,新旧钢绳接头割开;转动卷筒下降,旧钢绳全部系至地面,拆除卷筒另一侧钢绳压板螺栓;将新钢绳的两个绳头分别安装到卷筒两侧的钢绳压板螺栓上。本发明节约人力,提高吊车维护自动化水平。多条钢绳可同时更新,维修作业速度快。新旧钢绳连接可靠。
