The invention discloses a steel rope replacement method. In the steel rope replacement method, an old steel rope is wound by utilizing a winding roller, so that the old steel rope pulls a new steel rope to be wound on a corresponding loop movable pulley, the new steel rope is wound on a new steel rope roller, and when the old steel rope pulls the new steel rope to move, the new steel rope is gradually withdrawn from the new steel rope roller. Compared with the technical scheme that old steel ropes are lifted out section by section through a crane in the prior art, the steel rope replacement method has the advantages of being simple, convenient to operate, safe, applicable, unique, capable of greatly shortening the maintenance time, capable of increasing the production time and the like. The method is suitable for replacing steel ropes with limited space and larger lengths, and can also be used for replacing main coil steel ropes of large heavy bridge cranes in the metallurgical industry. The method can be popularized and has obvious social benefits. The invention further discloses a roller device.

    本发明公开了一种钢绳更换方法,在该更换方法中利用卷取辊筒来卷绕旧钢绳,以使旧钢绳牵引新钢绳绕在对应的活套动滑轮上,新钢绳卷绕在新钢绳辊筒上,在旧钢绳牵引新钢绳移动时,新钢绳会逐渐从新钢绳辊筒上退下。相较于现有技术中采用吊车将旧钢绳一段一段吊出的技术方案,本发明中钢绳的更换方法具有方法简单、操作方便、安全适用、方法独特,大大缩短检修时间、增加生产时间等优点。该方法适合空间受限、长度较长钢绳更换,也可用于冶金行业大型重型桥式吊车主卷钢绳更换。能够推广,社会效益显著。本发明还公开了一种辊筒装置。
