[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] In response to the problems mentioned in the above background technology, the embodiment of the present invention provides a torsional balance maintaining device for cable armor production to solve the above technical problems. The technical solution is as follows:

[0025] Example 1: See Figure 1-Figure 5 .

[0026] A torsional balance maintaining device for cable armor production, comprising:

[0027] The armoring machine distribution plate 100 has a plurality of trapezoidal groove threading holes 110 provided on the circumferential edge of the armoring machine distribution plate 100;

[0028] A guide mechanism 200 is provided on the front side of the armoring machine distribution plate 100 at the position of each trapezoidal slot threading hole 110;

[0029] The guide mechanism 200 includes a distribution plate 210 vertically fixed on the armoring machine distribution plate 100, and a first guide wheel 230, a second guide wheel 220 and a third guide wheel 240 sequentially connected to the distribution plate 210; the second guide wheel 220 is provided with a ring-shaped trapezoidal groove 221 along its circumference.

[0030] In this embodiment, the first guide wheel 230, the second guide wheel 220, and the third guide wheel 240 are arranged in a herringbone shape; the second guide wheel 220 is located in the middle; the design of the first, second, and third guide wheels being arranged in a herringbone shape can effectively guide the armored steel wire, forming a relatively fixed motion trajectory, and reducing instability during movement.

[0031] In this embodiment, the first guide wheel 230 and the second guide wheel 220 are both circular guide wheels.

[0032] The first guide wheel 230 is responsible for guiding the armored steel wire into the guide mechanism 200, ensuring that the steel wire can pass through each guide wheel smoothly;

[0033] The second guide wheel 220 is provided with a trapezoidal groove 221 on its circumference, which can effectively grasp the armor wire and exert a certain pressure on it, so that the wire moves along a preset trajectory and prevents it from deflecting or "turning over" during movement;

[0034] The third guide wheel 240 continues to guide the armored steel wire so that it can eventually smoothly enter other process parts of the armoring machine.

[0035] The combination and structural arrangement of the guide wheels on the guide mechanism 200 allow the entering armored steel wire to form a W-shaped path in the guide mechanism 200. This path locks the movement trajectory of the armored steel wire and prevents the armored steel wire from "turning over" during movement. In addition, the structural design of the guide mechanism 200 makes the stress on the passing armored steel wire more uniform during the forming process, thereby reducing the generation of internal stress and reducing the torsional imbalance caused by uneven tension.

[0036] Example 2: See Figure 2 .

[0037] A torsional balance maintaining device for cable armor layer production also includes: a telescopic cylinder mechanism;

[0038] The telescopic cylinder mechanism includes a first telescopic cylinder 310 and a second telescopic cylinder 320;

[0039] The second telescopic cylinder 320 is fixed to the rear side of the armoring machine distribution disk 100, and the first telescopic cylinder 310 is fixed to the process position of the armoring machine adjacent to the armoring machine distribution disk 100; the second telescopic cylinder 320 is embedded in the outer surface of the first telescopic cylinder 310 and the first telescopic cylinder 310 and the second telescopic cylinder 320 are locked by screws.

[0040] In this embodiment, a threaded hole 321 is provided on the second telescopic tube 320 , and a screw is inserted into the threaded hole 321 to lock the first telescopic tube 310 and the second telescopic tube 320 .

[0041] By designing the telescopic cylinder mechanism, the tension of the armored steel wire before entering the guide mechanism 200 can be optimized and adjusted; reasonable tension can prevent the steel wire from "turning over" during the forming process, ensuring the uniformity and reliability of the armor layer.

[0042] The working method of the torsion balance maintaining device for cable armor production provided by the embodiment of the utility model is as follows:

[0043] 1. First, adjust the translational sliding position of the second telescopic cylinder 320 on the first telescopic cylinder 310 to adjust and control the distance between the armoring machine distribution plate 100 and the adjacent process part (compression structure) in front of it. By optimizing the telescopic cylinder mechanism, the tension force of the armor steel wire during the forming process can be better optimized and eliminated. When the second telescopic cylinder 320 reaches the appropriate position, it is fixed with screws.

[0044] 2. When the armored steel wires reach the armoring machine distribution plate 100, they first pass through the trapezoidal groove threading holes 110 of the armoring machine distribution plate 100 one by one, and then enter the guide mechanism 200. In the guide mechanism 200, they first pass through the first guide wheel 230, then are stuck in the trapezoidal groove 221 of the second guide wheel 220, and then pass through the third guide wheel 240 and are led out and then enter other process structures of the armoring machine. The cooperation of the guide wheels in the above-mentioned guide mechanism 200 causes the armored steel wire to be extruded into a W shape and positioned, locking the motion trajectory of the armored steel wire and making the stress on the armored steel wire more uniform during the forming process.

[0045] 3. The utility model discloses a stretchable barrel mechanism and guide mechanism cooperate, the movement track of armoring steel wire is locked, can prevent the armoring steel wire in the movement process produce " turn over " the situation, and the tension of armoring steel wire is eliminated before guide mechanism, further prevent the steel wire armoring layer when forming appear " turn over " the situation, simultaneously, the cooperation of above -mentioned structure, the generation of armoring steel wire internal stress is reduced, make the cable own strength get effective improvement, and the armoring layer appears fatigue life to reach the design year to get effective improvement.
