As an indispensable part of the power system, the scale of production and laying of wires and cables continues to increase, which puts forward higher requirements on the laying device to ensure that the cables can be neatly and orderly placed and transported during the entire construction or production process.

[0034] ① Embodiment 1

[0036] like Figure 5 As shown, two rubber brush blocks 13 are symmetrically arranged at both the front and rear ends of the processing wire drum 11, and the surfaces of the rubber brush blocks 13 are symmetrically fixedly connected with fixed cylinders 16, and the surface of the fixed cylinder 16 is slidably connected with a moving rod 14, one end of the moving rod 14 is fixedly connected to the surface of the processing wire drum 11, and the surface of the moving rod 14 is sleeved with a spring 2 15, one end of the spring 2 15 is fixedly connected to the surface of the moving rod 14, and the other end of the spring 2 15 is fixedly connected to the surface of the fixed cylinder 16; the processing wire drum 11 releases waterproof or lubricating substances, such as talcum powder or moisture-absorbing powder, to the passing cables, and the two rubber brush blocks 13 are used to wipe the cables passing through the processing wire drum 11, and the substances applied to the cables are evenly applied;

[0037] The front and rear ends of the processing wire drum 11 are both slidably connected with a movable rod 17, the bottom end of the movable rod 17 is fixedly connected to the surface of the top rubber brush block 13, the top of the movable rod 17 is evenly fixedly connected with three sealing blocks 20, the top of the processing wire drum 11 is fixedly connected with a accommodating cylinder 12, the interior of the accommodating cylinder 12 is fixedly connected with a sealing orifice plate 19, the sealing block 20 is slidably connected to the sealing orifice plate 19, when the sealing block 20 moves out of the sealing orifice plate 19, the surface treatment medium inside the accommodating cylinder 12 is injected into the processing wire drum 11, the inner wall of the processing wire drum 11 is evenly provided with a plurality of leakage holes 18, a cavity is provided inside the processing wire drum 11, and the leakage hole 18 is connected with the cavity inside the processing wire drum 11.

The uniform pay-off of the cable makes the overall construction more stable. Especially when wiring over long spans and complex paths, the dynamic redundancy elimination mechanism can maximize the avoidance of instability caused by winding.

[0040] ② Embodiment 2

[0041] On other levels, this embodiment also provides another optimization mechanism based on Embodiment 1, specifically a wire-straightening mechanism. As Figure 7 shown, a wire-straightening mechanism is provided at the top of the processing bobbin 11. The wire-straightening mechanism is used to follow the pay-off process of the cable and synchronously correct the winding trajectory of the wound cable on the winding spool 2 in a cycle;

[0042] The wire-straightening mechanism includes a connecting winding shaft 8. The left and right ends of the connecting winding shaft 8 are respectively fixedly connected to the left and right limiting brackets 5. The connecting winding shaft 8 is used to swing synchronously following the running process of the limiting brackets 5. Three movable shafts 9 are horizontally and slidably connected through the surface of the connecting winding shaft 8. A wire clamping plate 21 is arranged on the back of the connecting winding shaft 8. The backs of the movable shafts 9 are all fixedly connected to the front of the wire clamping plate 21. Springs 10 are sleeved on the surfaces of the movable shafts 9. One end of each spring 10 is fixedly connected to the surface of the corresponding movable shaft 9, and the other end of each spring 10 is fixedly connected to the surface of the connecting winding shaft 8;

[0043] One side of the wire clamping plate 21 close to the winding spool 2 is in a wavy groove shape, and the wavy groove on the surface of the wire clamping plate 21 is adapted to the winding trajectory of the cable on the winding spool 2.

[0044] Working principle: When the present invention is specifically implemented, the cable is wound by the winding spool 2. When wire pay-off is required, the user needs to pull apart two rubber brush blocks 13 on both sides of the processing bobbin 11 respectively, pass the cable through the processing bobbin 11, and then release the rubber brush blocks 13 so that the rubber brush blocks 13 cover the cable, and talcum powder is injected into the receiving cylinder 12 in advance;

[0045] When the wire starts to be released, the wire passing through one end of the processing wire drum 11 is pulled and pulled, driving the wire to be released. At this time, the winding spool 2 rotates, and the movable rotating rod 3 is driven to rotate by the winding spool 2. During the rotation of the movable rotating rod 3, the top end of the pulling swing rod 4 swings cyclically. Figure 9 As shown, the movement track of the swing rod 4 is limited by the limit bracket 5. The swing rod 4 swings back and forth in a circular motion. Figure 1 As shown, the swing rod 4 pushes the limit bracket 5 to rotate back and forth. During this process, the swing rod 4 drives the movable rocking plate 6 to shovel forward cyclically and then reset. The front end of the movable rocking plate 6 is in a cyclic swinging state. When it is at the maximum shoveling distance, that is, Figure 1 As shown, the movable rocking plate 6 is in a plane shape. At this time, if the movable rocking plate 6 continues to move, it will be pulled by the swing rod 4, and the movable rocking plate 6 will move backward. The front end of the movable rocking plate 6 will gradually tilt downward. The movement trajectory of the front end of the movable rocking plate 6 is consistent with the rear end, presenting a front and rear arc movement trajectory, thereby forming a cyclic shoveling process, so that the cable inside the processing drum 11 is swung. The inner wall of the processing drum 11 is made of elastic rubber material, and then during the swinging process, the cable is horizontally impacted, which assists in driving the cable to be gradually fed, thereby eliminating the cable winding surplus on the surface of the winding spool 2, and assisting in the release of the cable;

[0046] like Figure 5 As shown, during the continuous swinging of the movable rocking plate 6, the swinging amplitude of the cable is increased. During this process, centrifugal force is applied to the cable, so that the cable is in a swinging state. The cable circulates against the rubber brush block 13, so that the rubber brush block 13 slides on the surface of the movable rod 14 and resists the spring 2 15. Under the rebound action of the spring 2 15, the rubber brush block 13 is in a continuous rebound state. The rubber brush block 13 drives the movable rod 17 to swing back and forth, and the movable rod 17 drives the sealing block 20 to continuously move out and move into the sealing orifice plate 19. When the sealing block 20 moves out of the sealing orifice plate 19, the talcum powder inside the accommodating tube 12 leaks into the processing wire barrel 11 and is coated on the surface of the cable through the leakage hole 18. During the continuous pulling process of the cable, the rubber brush block 13 wipes the surface of the cable and fully and evenly spreads the coated talcum powder.

[0047] like Figure 7 As shown, during the reciprocating rotation of the limit bracket 5, the connecting winding shaft 8 is synchronously driven to rotate in a circular manner, and the connecting winding shaft 8 drives the wire clamping plate 21 to swing back and forth. The wire clamping plate 21 resists the cable wound on the surface of the winding reel 2 and performs a circular correction on the cable winding trajectory. As the cable decreases, the processing reel 11 continuously rebounds, so that the movable shaft 9 drives the wire clamping plate 21 to maintain resistance to the cable.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
