The invention discloses a method for quickly replacing steel wire ropes of a metallurgical crane, relating to a crane rope and comprising the following steps of: placing a lifting appliance on a placing platform, then disassembling the steel wire ropes on the crane, replacing the steel wire ropes with new steel wire ropes, and calibrating a reference plane and reference points in one-to-one correspondence with the four steel wire ropes on the lifting appliance; a rope head of a new steel wire rope is selected as a reference rope head, the reference rope head is fixed to the lifting appliance, and meanwhile the reserved length of the reference rope head is obtained; and levelness difference values between the other reference points and the reference points corresponding to the reference rope head are sequentially obtained, and the reserved lengths of the other rope heads are obtained through calculation according to the reserved length of the reference rope head and the levelness difference values. After the new and old steel wire ropes are replaced, the brightness of the lifting appliance is flush, the operation of adjusting the steel wire ropes on a winding drum in the prior art is avoided, the maintenance difficulty and the labor intensity are reduced, and the production efficiency is improved.
本发明公开了一种冶金起重机快速更换钢丝绳的方法,涉及起重机绳索,将吊具置于放置平台上,然后将起重机上的钢丝绳拆卸下来,并更换上新的钢丝绳,在所述吊具上标定参考平面以及与四根钢丝绳一一对应的参考点;选取一新的钢丝绳的绳头作为参考绳头,将参考绳头固定在吊具上,同时获取所述参考绳头的预留长度;依次获取其他所述参考点与参考绳头所对应的参考点之间的水平度差值,根据所述参考绳头的预留长度和水平度差值计算获取其他绳头的预留长度。本发明确保新旧钢丝绳的替换完成后,吊具亮度的高低度平齐,避免了如现有技术中需要在卷筒上调整钢丝绳的操作,降低了检修难度和劳动强度、提高生产效率。
