[0044] The power component 1 has a winch 3 and a driving frame 4, and the winch 3 and the driving frame 4 are both distributed on the same axis;

[0045] On both sides of the driving frame 4, a first cable pay-off frame 5 and a second cable pay-off frame 6 are respectively provided. The first cable pay-off frame 5 and the second cable pay-off frame 6 are parallel to each other and spaced apart. A rotatable cable reel 7 is installed between the first cable pay-off frame 5 and the second cable pay-off frame 6. The driving frame 4 is fixedly connected to one end of the cable reel 7 close to the first cable pay-off frame 5. A steel wire rope 8 is provided between the driving frame 4 and the winch 3. One end of the steel wire rope 8 is wound around the winch 3, and the other end of the steel wire rope 8 is wound around the driving frame 4;

[0046] The resistance assembly 2 has a guiding group wheel frame 9. The cable 43 passes through the guiding group wheel frame 9 and is fixedly connected to the cable reel 7.

Secondly, start the winch 3 in the power assembly 1, so that the winch 3 winds the steel wire rope 8. The steel wire rope 8 will drive the driving frame 4 to rotate. The driving frame 4 will drive the cable reel 7 to rotate between the first cable pay-off frame 5 and the second cable pay-off frame 6. The cable winding onto the reel is realized by the rotation of the cable reel 7. The cable 43 is guided by the guiding group wheel frame 9. At the same time, it is ensured that the cable 43 is more tightly wound on the cable reel 7 without loosening.

[0048] A medium-voltage cable winding-up and reeling device for a wind turbine tower barrel disclosed in this embodiment has a power assembly 1, which makes it easy to wind the cable 43 onto the cable reel 7. By setting the guiding group wheel frame 9, the recovered cable 43 is tightly wound without loosening. Furthermore, a medium-voltage cable winding-up and reeling device for a wind turbine tower barrel has the beneficial effects of saving time and effort, high recovery efficiency, saving labor costs, being applicable to various occasions, facilitating cable recovery, and the recovered cable being tightly wound without loosening.

[0049] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the driving frame 4 is of a cross-shaped structure. The driving frame 4 has a first side plate 10 and a second side plate 11. The first side plate 10 and the second side plate 11 are parallel to each other and spaced apart. A number of connecting rods 12 are provided between the first side plate 10 and the second side plate 11. One ends of the number of connecting rods 12 are fixedly connected to the side of the first side plate 10 close to the second side plate 11, and the other ends of the number of connecting rods 12 are fixedly connected to the side of the second side plate 11 close to the first side plate 10. The other end of the steel wire rope 8 is wound around the number of connecting rods 12 along the circumferential direction of the driving frame 4. By winding the other end of the steel wire rope 8 around the combination formed by the number of connecting rods 12, only by pulling the steel wire rope 8 can the driving frame 4 be rotated, and then the cable reel 7 can be rotated to realize the recovery of the cable 43. The first side plate 10 and the second side plate 11 effectively limit the position of the steel wire rope 8 and prevent the steel wire rope 8 from displacing.

[0050] Both the first side plate 10 and the second side plate 11 are channel steels, which effectively improves the strength of the first side plate 10 and the second side plate 11, and avoids the fracture of the first side plate 10 and the second side plate 11 during rotation.

[0051] A through hole 13 is provided at the center of the first side plate 10 and the second side plate 11. A rotatable rotating rod 14 is fitted in the through hole 13. One end of the rotating rod 14 is rotatably connected to the first wire reel 5. The other end of the rotating rod 14 passes through the through hole 13 and the cable reel 7 and is rotatably connected to the second wire reel 6. The cable reel 7 can be lifted by the rotating rod 14, which facilitates the rotation of the cable reel 7, and thus is beneficial to the recovery of the cable.

[0052] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , both the first wire reel 5 and the second wire reel 6 have a base 15. A first upright post 16 and a second upright post 17 are vertically connected to the base 15. A top beam 18 is fixedly connected between the tops of the first upright post 16 and the second upright post 17. A plurality of support rods 19 are fixedly connected to the outer edge of the base 15. One ends of the plurality of support rods 19 away from the base 15 are all fixedly connected to the top beam 18.

The plurality of support rods 19 effectively improves the overall stability of the first wire reel 5 and the second wire reel 6, and at the same time, improves the bearing capacity of the first wire reel 5 and the second wire reel 6.

[0053] A number of first holes 20 and a number of second holes 21 are respectively formed in the outer walls of the first upright column 16 and the second upright column 17. The number of first holes 20 are uniformly distributed along the axial direction of the first upright column 16, and the number of second holes 21 are uniformly distributed along the axial direction of the second upright column 17. A first support bracket 22 and a second support bracket 23 are successively arranged in the axial direction between the first upright column 16 and the second upright column 17. Both ends of the first support bracket 22 and the second support bracket 23 are respectively sleeved on the first upright column 16 and the second upright column 17. A first bolt 24 and a second bolt 25 are arranged outside the first upright column 16.

On-site staff adjust the heights of the first support bracket 22 and the second support bracket 23 according to the diameter of the cable reel 7. Then, the first bolt 24 and the second bolt 25 are respectively inserted into the corresponding first holes 20, and the third bolt 26 and the fourth bolt 27 are respectively inserted into the corresponding second holes 21, so as to limit the first support bracket 22 and the second support bracket 23 on the first upright column 16 and the second upright column 17, so that the first cable unreeling rack 5 and the second cable unreeling rack 6 can adapt to cable reels 7 of various diameters, improving the applicable range of the equipment.

[0054] The top surface of the first support bracket 22 clamps a rotatable first rotating wheel 28 and a second rotating wheel 29. The first rotating wheel 28 and the second rotating wheel 29 are distributed at intervals. One end of the rotating rod 14 is rotatably supported between the first rotating wheel 28 and the second rotating wheel 29. The arrangement of the first rotating wheel 28 and the second rotating wheel 29 facilitates the rotation of the rotating rod 14, reduces the rotation resistance of the rotating rod 14, and thus is beneficial to the rotation of the cable reel 7.

[0055] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the guiding group wheel frame 9 has a guiding frame 30. Inside the guiding frame 30, there is a rotatable first horizontal guiding wheel 31.

On the side of the first vertical guiding wheel 32 and the second vertical guiding wheel 33 away from the first horizontal guiding wheel 31, there is a rotatable second horizontal guiding wheel 34. On the side of the second horizontal guiding wheel 34 away from the first horizontal guiding wheel 31, there are a rotatable third horizontal guiding wheel 35 and a rotatable fourth horizontal guiding wheel 36. The third horizontal guiding wheel 35 and the fourth horizontal guiding wheel 36 are symmetrically distributed with respect to each other.

In this way, it not only plays a role in guiding the cable, but also ensures that the cable on the cable reel 7 is tight and does not become loose.

[0056] A fixed pulley 37 is provided between the winch 3 and the driving frame 4. The fixed pulley 37 has a pulley seat 38. A rotatable pulley 39 is clamped on the pulley seat 38. The steel wire rope 8 is located between the pulley 39 and the pulley seat 38. The fixed pulley 37 has the function of limiting the position of the steel wire rope 8. At the same time, it changes the force direction of the winch 3. When installing the fixed pulley 37, the winch 3 bears a horizontal pulling force when winding the steel wire rope 8, and vice versa, it bears an obliquely upward pulling force. Comparing with the winch 3 bearing a horizontal pulling force, it is beneficial to the stable operation of the winch 3.

The support frame 40 can provide a supporting effect, which is convenient for the motor 42 to drive the drum 41 to rotate. At the same time, it is beneficial for the staff to fix the winch 3 on the ground to prevent the winch 3 from displacing when the drum 41 retracts the steel wire rope 8.

[0059] Step 1, first wind the steel wire rope 8 of the winch 3 around the driving frame 4;

[0060] Step 2, then connect the driving frame 4 with the wound steel wire rope 8 to the cable reel 7 through bolts or clamps;

[0061] Step 3, install the fixed pulley 37 for guiding;

[0062] Step 4: Fix the guiding group wheel frame 9 on the ground;

[0063] Step 5: Pass the medium-voltage cable head through the guiding group wheel frame 9 and fix it to the cable reel 7;

[0064] Step 6: Start taking up the cable onto the reel. Start the winch 3, drive the driving frame 4 to rotate through the steel wire rope 8, thereby driving the cable reel 7 to rotate, and tractionally wind the medium-voltage cable 43 onto the cable reel 7. The cable 43 passes through the guiding group wheel frame 9 so that the cable 43 is stressed, ensuring that the wound cable is tight and does not come loose.
