[0002] When replacing the crane wire rope, it is necessary to cut a certain length of wire rope from the wire winding drum. The general practice is to manually break the rope from the winding drum, straighten it, and finally measure it. Finally, the measured wire rope is wound on the winding drum. At the same time, the replaced waste wire rope needs to be reeled up for later recycling.

The rope-releasing device includes a base I, which is connected to a rotating shaft I through a bearing, and a support seat for supporting a winding disk I is arranged on the rotating shaft I. A base is arranged inside the base I, and a universal wheel is arranged below the base, and a jack is arranged above the base, and the top of the jack is fixedly connected to the base I; the rope-collecting device includes a base II, and a movable support frame and a fixed support frame are arranged on the base II. The movable support frame is connected to a clamping shaft through a bearing, and the fixed support frame is connected to a rotating shaft II driven by a power device through a bearing, and a winding disk II is arranged between the clamping shaft and the rotating shaft II. A lead screw driven by a motor and a slider cooperating with the lead screw are also arranged on the base II, and a pull ring is arranged on the slider. When using this tooling, pass the wire rope through the pull ring on the slider. During the winding process, the slider can move slowly under the drive of the motor, ensuring that the wire rope is neatly arranged on the winding drum II. By measuring the number of turns of the wire rope on the winding drum II, the length of the wire rope can be calculated, reducing manual labor.
