Fig. 1 is a schematic structural view of a winding device according to an embodiment of the present disclosure, and fig. 2 is a schematic structural view of the winding device shown in fig. 1 at another angle.

Referring to fig. 1 and 2, an embodiment of the present application provides a wire winding device for accommodating a cable 4, the wire winding device includes a frame 1, a winding roll 2, and at least one wire pressing mechanism 3.

The frame 1 is used for being fixed on a crane.

The spool 2 is rotatably coupled to the frame 1, the spool 2 has a central axis extending in the first direction X, and an accommodating passage 21 for accommodating the cable 4 is formed on an outer circumferential surface of the spool 2, the accommodating passage 21 spirally extending around the central axis of the spool 2. Optionally, the frame 1 includes a shaft portion extending along the first direction X, and the winding roll 2 is sleeved outside the shaft portion to be rotatably connected to the frame 1.

At least one line pressing mechanism 3, the line pressing mechanism 3 includes a fixing shaft 31 and a line pressing unit 32, the fixing shaft 31 is fixed to the frame 1, an extending direction of the fixing shaft 31 is parallel to the first direction X, and the fixing shaft 31 includes a first end 311 and a second end 312 arranged along the extending direction.
