The invention relates to a method for replacing a steel wire rope of a bridge crane, which is characterized by comprising the following steps of: S1, manufacturing a steel frame capable of transversely supporting the whole roll of steel wire rope and rotating, and putting the whole roll of new steel wire rope with the diameter of 22mm on the steel frame; S2, temporarily closing ascending and descending limits in a hoisting mechanism of the bridge crane, and preparing electric welding and a cutting knife in place for cutting and welding a steel wire rope; S3, descending a lifting hook set in the hoisting mechanism to the ground, detaching steel wire rope pressing plates on the two sides of a winding drum, setting the position, two meters away from a movable pulley of the lifting hook set, of the winding drum to cut off, and then connecting the movable pulley with the end of the new steel wire rope in a welded mode; S4, starting the controller to enable the hoisting mechanism to be in an upshift; and S5, starting the hoisting mechanism, integrally winding the new steel wire rope on the winding drum, and lifting the lifting hook set. The method for replacing the steel wire rope is designed for replacing the lifting steel wire rope of the bridge crane hook, is few in working procedures and simple in process.
本发明涉及一种桥式起重机更换钢丝绳的方法,其特征在于,包括有以下步骤:S1、制作一个能把整卷钢丝绳横向支撑起来并能旋转的钢架,将整卷直径22mm的新钢丝绳放在钢架上;S2、将桥式起重机的起升机构中的上升、下降限位暂时封闭,电焊和割刀准备到位,为切割和焊接钢丝绳作准备;S3、将起升机构中的吊钩组下降到地面,卸掉卷筒上两侧的钢丝绳压板,在离吊钩组动滑轮两米处将其割断,然后将其与新钢丝绳端部焊接连接在一起;S4、启动控制器使得起升机构处于上升档;S5、开动起升机构,把新钢丝绳整体缠绕在卷筒上,提升起吊钩组;该钢丝绳更换方法针对的是桥式起重机吊钩起升钢丝绳更换而设计的方法,该方法工序少,工艺简单。
