[0046] Both ends of the auxiliary winding disc 2 are respectively provided with a first bearing 24 and a second connecting shaft 26, and a first bushing 23 is assembled outside the first bearing 24. The first bearing 24 is adapted to the hollow shaft 15, so that the main winding disc 1 and the auxiliary winding disc 2 are connected through the hollow shaft 15, the first bearing 24 and the first bushing 23, enabling the main winding disc 1 and the auxiliary winding disc 2 to rotate relatively freely. In this embodiment, the main winding disc 1, the hollow shaft 15, the first bearing 24, the auxiliary winding disc 2 and the second connecting shaft 26 are coaxially arranged. Those skilled in the art can also make adaptive adjustments to the relative positions of the main winding disc 1, the hollow shaft 15, the first bearing 24, the auxiliary winding disc 2 and the second connecting shaft 26 according to specific situations, as long as it is ensured that the first wire passing hole 11 and the second wire passing hole 21 are mutually penetrated through the hollow shaft 15, the cable can pass through the first wire passing hole 11 and the hollow shaft 15 and then pass out through the second wire passing hole 21 at one time, and the main winding disc 1 and the auxiliary winding disc 2 can rotate relatively freely. The second connecting shaft 26 cooperates with the third bearing 43 of the second support base 45 to fixedly connect the auxiliary winding disc 2 to the second support base 45. In this embodiment, the second connecting shaft 26 is preferably a solid shaft.

[0047] Both ends of the main winding disc 1 are also respectively fixedly connected with a first baffle 16 and a second baffle 17. The first baffle 16 and the second baffle 17 are of disc structure, and their radii are larger than the radius of the main winding disc 1. The first baffle 16, the second baffle 17 and the main winding disc 1 are coaxially arranged. The main winding disc 1, the first baffle 16, the second baffle 17, the first connecting shaft 12 and the hollow shaft 15 can be arranged as an integral structure. A number of lightweight round holes 5 are arranged in a circular array around the center position of the first baffle 16. In this embodiment, eight are provided. A number of first wire clamps 13 are also fixedly connected to the first baffle 16, which are used to fix the wire heads of the cables wound around the main winding disc 1 to prevent the cables from falling off. A number of connecting holes 14 are arranged in a circular array around the center position of the second baffle 17.

[0048] Both ends of the secondary winding disc 2 are respectively fixedly connected with a third baffle 27 and a fourth baffle 28.

A number of second wire clamps 25 are also fixedly connected to the fourth baffle 28, which are used to fix the wire heads of the cables wound around the secondary winding disc 2 to prevent the cables wound on the secondary winding disc 2 from falling off during the rotation of the main winding disc 1. Those skilled in the art can also make adaptive adjustments to the structures of the third baffle 27 and the second baffle 17, as long as the main winding disc 1 can be detachably connected to the secondary winding disc 2, so that when the second baffle 17 and the third baffle 27 are fixedly connected, the main winding disc 1 and the secondary winding disc 2 can rotate synchronously. When the second baffle 17 and the third baffle 27 are not fixedly connected, the secondary winding disc 2 can rotate independently and can cooperate with the main winding disc 1 and the secondary winding disc 2 to realize winding.

[0049] The second connecting shaft 26 also cooperates with the second shaft sleeve 31 on the crank device 3. The second shaft sleeve 31 on the crank device 3 is located on the right side of the third bearing 43, that is, the crank device 3 is located on the right side of the second support base 45, which is convenient for the operator to operate the crank device 3.

That is, the crank device 3 is connected to the secondary winding disc 2. When the second baffle 17 and the third baffle 27 are not fixedly connected, the crank device 3 can rotate the secondary winding disc 2 alone to wind and unwind the cable. When the second baffle 17 and the third baffle 27 are fixedly connected by the connecting bolts 42, the crank device 3 can rotate the secondary winding disc 2 and the main winding disc 1 simultaneously. The crank device 3 can also be connected to the main winding disc 1 according to the actual situation. In this embodiment, the crank arm 33 is riveted to the holding member 34 through a nut. The holding member 34 is a conical structure. After use, the conical holding member 34 can be pulled outwards to fold and retract the crank device 3, which is convenient for the movement and fixation of the entire cable winding and unwinding device. In this embodiment, the fixing device 32 is a bolt.

[0050] A bolt hook 41 is also fixedly connected to the first support base 44 and / or the second support base 45 for hanging and connecting a bolt 42.

[0051] To facilitate the movement of the cable winding and unwinding device of the present utility model, a moving device, such as a roller, can also be movably connected to the support base 4.

[0052] Regarding the number and size of the lightweight round holes 5, connection holes 14, and threaded holes 22, those skilled in the art can make adaptive adjustments according to the actual situation.

[0053] Regarding the shapes of the first baffle 16, second baffle 17, third baffle 27, and fourth baffle 28, those skilled in the art can also make adaptive adjustments to them, such as regular polygon structures or other irregularly shaped plate-like structures, as long as it is ensured that the lower surface of the support base 4 is lower than the lower surfaces of the first baffle 16, second baffle 17, third baffle 27, and fourth baffle 28, so that the main winding disc 1 and the auxiliary winding disc 2 are in a suspended state, facilitating the winding and unwinding of the cable.

[0054] The working principle of the present utility model:

[0055] When using the cable winding and unwinding device of the present utility model for the first time to assemble a cable, the hollow shaft 15 is docked with the first bearing 24 to connect the main winding disc 1 and the auxiliary winding disc 2. The support base 4 suspends and supports the main winding disc 1 and the auxiliary winding disc 2. At this time, the auxiliary winding disc 2 can rotate independently. The cable is sequentially passed through the first wire passing hole 11, the inside of the main winding disc 1, the hollow shaft 15, and the inside of the auxiliary winding disc 2, and finally passes out from the second wire passing hole 21. After pulling out an appropriate length of the cable, operate the crank device 3. The crank device 3 controls the rotation of the auxiliary winding disc 2, thereby realizing the winding of the cable on the auxiliary winding disc 2. When an appropriate length of the cable is wound around the auxiliary winding disc 2, use the connecting bolt 42 to fixedly connect the main winding disc 1 and the auxiliary winding disc 2. Operate the crank device 3 again, and the main winding disc 1 and the auxiliary winding disc 2 rotate simultaneously. At this time, the remaining cable outside the main winding disc 1 is wound around the main winding disc 1 until the winding is completed. Finally, fix the wire ends at both ends of the cable to the first wire clamp 13 and the second wire clamp 25 respectively. The wire end on the auxiliary winding disc 2 can also be fixed to the second wire clamp 25 before the main winding disc winds the cable after the winding on the auxiliary winding disc 2 is completed.

[0056] When it is necessary to unwind the cable, the wire ends at both ends can be removed separately or simultaneously according to the need for unwinding, that is, the cable wound around the main winding disc 1 or the auxiliary winding disc 2 can be unwound separately, or the main winding disc 1 and the auxiliary winding disc 2 can be fixedly connected to realize the synchronous unwinding of the cable on the auxiliary winding disc 2 and the cable on the main winding disc 1. After unwinding, connect the two ends of the cable to the corresponding access points respectively, and fix the remaining cable on the main winding disc 1 and / or the auxiliary winding disc 2.

[0057] When using the cable winding and unwinding device of the present utility model for the second and subsequent winding operations, the auxiliary winding disc 2 can be rotated independently for winding, or the main winding disc 1 and the auxiliary winding disc 2 can be rotated simultaneously for winding, so as to realize the flexible and convenient winding and unwinding of bidirectional cables.

[0058] Regarding the specific structure of the present utility model, it should be noted that the connection relationships between the various component modules adopted by the present utility model are definite and achievable. Except for the special descriptions in the embodiments, the specific connection relationships can bring corresponding technical effects, and on the premise of not relying on the execution of corresponding software programs, the technical problems proposed by the present utility model can be solved.
