In a narrow sense, a cable refers to an insulated cable, which can be defined as a collection composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, total protection layer and outer protection layer. A cable can also have additional uninsulated conductors.

[0003] For example, the patent document with the publication number of CN 221226975 U discloses a power cable traction device, including a vehicle plate, symmetrically arranged support plates fixedly connected to the vehicle plate, a rotating roller rotatably connected between the support plates, an installation frame fixedly connected between the support plates, symmetrically arranged applicable mechanisms on the installation frame, symmetrically arranged support rods fixedly connected to the vehicle plate, sliders slidably connected in the support rods, a wire pay-off roller rotatably connected between the sliders, a guide rod fixedly connected inside one of the support rods, a toothed plate fixedly connected to one of the sliders, guide plates fixedly connected to both sides of the toothed plate, and an installation block fixedly connected to the other support rod. The beneficial effect of the utility model is that the original limitation is removed, the height of one end of the wire can be freely adjusted, and the rotating roller can be applicable to wires with different thicknesses.

[0025] A center frame 6, the center of the surface of the support frame 1 is fixedly connected with a center frame 6, the center of the inner wall of the center frame 6 is provided with a pay-off machine base 7, the inside of the pay-off machine base 7 is provided with a cable reel 8, the top of the center frame 6 is fixedly connected with a top frame 9, the top of the top frame 9 is provided with an electric push rod 10, the bottom of the top frame 9 is movably connected with an arc-shaped cover 11 through the electric push rod 10, and the bottom of the arc-shaped cover 11 is provided with a fitting rubber pad 12. Starting the electric push rod 10 on the surface of the top frame 9 drives the arc-shaped cover 11 and the fitting rubber pad 12 to be adaptively abutted against the top of the cable reel 8. When the cable reel 8 rotates and pays off on the pay-off machine base 7, a top limit protection operation is carried out for continuous, stable and smooth pay-off limit.

[0026] Working principle: When in use, the operator first fixes the entire cable reel 8 to be unreeled on the unreeling machine base 7. Through the unreeling machine base 7, the entire cable reel 8 is rotated for unreeling operation. Then, the power cable at the unreeling position on the cable reel 8 can first pass through the limit wire sleeve 5 at the center inside the limit frame 2, and then pass through one end of the guiding cone cover 3.

During daily use, the operator can start the electric push rod 10 on the surface of the top frame 9 to drive the arc-shaped cover 11 and the fitting rubber pad 12 to be adaptively abutted against the top of the cable reel 8. When the cable reel 8 rotates and unreels on the unreeling machine base 7, the top limit protection operation is carried out for continuous, stable and smooth unreeling limit. At the same time, the entire cable reel 8 can be quickly positioned for loading and unloading at the unreeling machine base 7 along the push frame 13 and the loading guide frame 14, facilitating the replacement operation of the entire cable reel 8. The above is the entire working principle of the present utility model.
