The fundamental reason for the wrapped of the electric gourd steel wire rope is that the internal force of its own rotation drives the hook below for rotation. For ordinary electric gourds, in order to make the wire rope neatly arranged, the rope groove is indispensable, which means that the wire rope rotates inside the inside of the rotation of the wire. To make the hook not rotate, it can only be improved by the structure to prevent the wire rope from rotating. Pass to the hook to reach the stable effect of the hook when the wire rope is rotated, and the rotation device of the wire rope can meet this requirement well. The structure of the wire rotation device of the steel wire is shown in Figure 1. The upper connection shaft 1 and the sleeve 2 are connected through the thread, and the nail locks to form a one. After the connection shaft 5 is put into the sleeve, the lock mother 3 in the sleeve 3 The rotation is locked, so that the entire device is divided into two parts. These two parts are connected through the middle thrust bearing 4. The biggest feature of this device is that due to the existence of thrust bearing, the upper and lower parts can be rotated independently, that is, when the upper connection axis is rotated, the lower connection shaft is not moving, which is satisfying the problem of solving the problem of "twitching twist" of the wire rope.
