The invention discloses a method for replacing a traction cable of a cable crane, which comprises the following steps of: withdrawing a lifting cable on a lifting winding drum, coiling a new cable on the lifting winding drum, and arranging an auxiliary winch below a main tower; the conveying trolley is close to the main tower, and the old cable is fixed to the main tower; the main tower and the conveying trolley are connected through the rope, so that the old cable is separated from the conveying trolley; the rope head of the new rope bypasses the lifting pulley to be connected with the old rope; the auxiliary pull rope and the conveying trolley are separated, then the auxiliary pull rope is connected with the old cable, and the old cable and the conveying trolley are separated; separating the old cable from the main tower, taking up the rope by the auxiliary winch, and releasing the rope by the lifting drum, so that the new cable is wound along the winding path of the old cable; separating the new cable from the lifting drum, and separating two ends of the new cable from two ends of the conveying trolley; and the temporary rope is separated from the main tower and the conveying trolley, and the lifting rope is rewound on the lifting winding drum. According to the replacement method for the traction cable of the cable crane, the labor intensity is reduced, the danger is reduced, the replacement efficiency is improved, and the manual winding difficulty is avoided.
本发明公开了一种缆索起重机牵引索的更换方法,包括:将起升卷筒上起升索退出,把新索盘入起升卷筒上,在主塔下设辅助卷扬机;输送小车靠近主塔,将旧索固在主塔上;绳连主塔和输送小车,使旧索与输送小车分离;将新索的绳头绕过起升滑轮与旧索连接;分离辅助拉绳与输送小车,再将辅助拉绳与旧索连接,分离旧索与输送小车;分离旧索与主塔,辅助卷扬机收绳,起升卷筒放绳,使新索沿着旧索的缠绕路径缠绕;分离新索与起升卷筒,将新索两端与输送小车两端分接;分离临时绳与主塔和输送小车,将起升索重新缠绕在起升卷筒上。本缆索起重机牵引索的更换方法减少劳动强度大,降低危险性,提高更换效率,避免面对人工绕装难度。
