The invention relates to a crown block steel wire rope replacing method. According to the crown block steel wire rope replacing method, an old steel wire rope which is released from a winding drum andclose to the ground is cut off and connected with one end of a new steel wire rope, the fixed end of the other end of the old steel wire rope is loosened at the same time, a traction rope is connected at the fixed end of the old steel wire rope, then the winding drum is started, the old steel wire rope is released, the new steel wire rope is wound on the winding drum, when the joint of the new steel wire rope and the old steel wire rope reaches the fixed end of the winding drum, the connection of the new steel wire rope and the old steel wire rope is cut off, the winding drum is fixedly connected with the new steel wire rope through a winding drum pressing plate at the fixed end, and replacement of the new steel wire rope and the old steel wire rope is completed. According to the crown block steel wire rope replacing method, the labor intensity is lower, the working time is short, and the operation of replacing a new steel wire rope by rotating the winding drum for many times in the prior art is avoided.

    本发明涉及一种天车钢丝绳更换方法,本发明将卷筒放出的接近地面的旧钢丝绳割断,并与新钢丝绳的一端连接,同时松开旧钢丝绳的另一端的固定端,在旧钢丝绳的固定端处连接有牵引绳,然后启动卷筒,将放出旧钢丝绳的同时,将新钢丝绳卷绕至卷筒上,当新钢丝绳与旧钢丝绳连接处到达卷筒的固定端时,割断新钢丝绳和旧钢丝绳的连接,通过固定端卷筒压板将新钢丝绳将卷筒固定连接,完成新钢丝绳和旧钢丝绳的更换,本发明的劳动强度较低,作业时间短,避免了现有技术的卷筒多次转动才能更换新钢丝绳的操作。
