[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1-5 shown, several balance system assemblies 2 are arranged on the bracket body 1, and the several balance system assemblies 2 are arranged in a staggered manner to prevent interference with each other when the steel wire 3 moves.

[0029] The balance system assembly 2 includes a fixed plate pull rod seat 4, a spring 5, a spring pull rod 6, a spring pull rod seat 7, a chain pull rod 8, a balance rod shaft seat 9, a balance rod shaft 10, a balance rod 11, a second roller 12, a first stop block 13, a brake pad 14, a second stop block 15, a first roller 16, a chain 17, a third stop block 18, a brake disc 20, a fixed pin 21, and a fixed plate 22. The first roller 16 and the third roller 24 are fixed on the bracket body 1 and can rotate freely. A second stop block 15 is arranged on the first roller 16, and the second stop block 15 is used to keep the steel wire 3 sliding on the first roller 16 and not easy to fall off.

[0030] The balance rod shaft seat 9 and the fixed plate 22 are fixed on the bracket body 1.

[0031] One end of the third roller 24 is fixed with a brake disc 20, and a detachable and fixed third stop block 18 is arranged at the other end of the third roller 24. The third stop block 18 can clamp and fix the wire reel 19 between the brake disc 20 and the third stop block 18. A drive rod 23 is arranged on the brake disc 20, and the drive rod 23 is used in cooperation with the wire reel 19, so that the wire reel 19 can be decelerated in time after the brake disc 20 brakes.

[0032] The balance bar shaft 10 is fixed within the balance bar shaft seat 9 and can rotate freely. A balance bar 11 is fixed to the balance bar shaft 10. One end of the balance bar 11 is provided with a spring pull rod seat 7, and the other end is provided with a second roller 12 which can rotate freely. The second roller 12 is provided with a first stop 13 which is used to keep the steel wire 3 sliding on the second roller 12 and not easily falling off.

[0033] Both ends of the spring 5 are fixedly connected to the fixed plate pull rod seat 4 and the spring pull rod seat 7 respectively through the spring pull rod 6.

[0034] A chain pull rod 8 is provided on the balance bar 11. The chain 17 bypasses the brake disc 20 and its two ends are fixedly connected to the chain pull rod 8 and the fixed plate 22 respectively. A number of brake pads 14 are arranged between the chain 17 and the outer circumference of the brake disc 20. The brake pads 14 are fixedly connected to the chain 17 through the fixing pins 21.

[0035] Specific implementation process:

[0036] The steel wire 3 on the wire reel 19 passes through the first roller 16 and then through the second roller 12 and is drawn and twisted by the stranding machine. During production, if the stranding machine suddenly accelerates abnormally, the steel wire 3 will pull the second roller 12 to overcome the elastic force of the spring 5, causing the balance bar 11 to rotate clockwise. At the same time, it will pull the upper end of the chain 17 to move to the right. At this time, the brake pads 14 on the chain 17 will contact the brake disc 20, reducing the rotational speed of the brake disc 20 and preventing the wire reel 19 from "running away". After the moving speed of the steel wire 3 decreases, the spring 5 pulls the balance bar 11 back to its normal state, thereby realizing the dynamic control of the rotational speed of the wire reel 19.

[0037] The above achieves the design purpose.
