Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, and in particular to a tension wire feeding device. Background Technology

[0002] Tensioner laying devices are specialized equipment used in power construction or cable production for laying conductors or cables. Through the cooperation of components such as a traction machine and a tensioner, they maintain a constant tension on the conductor throughout the laying process, preventing damage from friction with the ground and ensuring efficiency and safety in stringing operations or cable production. Their core functions include achieving damage-free conductor laying, precise control of sag, and synchronous and coordinated construction of multiple split conductors.

[0003] Based on this, Chinese patent document CN104218499B discloses a tension cable laying device, which includes a base frame. A cable reel shaft assembly for mounting cable reels is mounted on the base frame. After the cable reel is mounted, its relative position to the cable reel shaft assembly is fixed. The cable reel shaft assembly includes a reel shaft that mates with the central hole of the cable reel. The reel shaft is rotatable along its own central axis. A braking device is connected to the reel shaft to brake its rotation. The braking force applied to the reel shaft by the braking device is adjustable. During construction, the cable laying device disclosed in this patent document, by applying braking force to the cable, straightens and tightens the cable, ensuring that the cable between suspension points is completely suspended in the air, preventing it from drooping onto the track and obstructing the construction of other equipment, thus improving construction efficiency.

[0004] However, existing tension cable laying devices still have technical problems such as the inability to manually intervene in the cable laying speed and the inability to effectively stop the vehicle after the motor stops. Specifically, in the existing technology, the approach to constant tension cable laying devices can be basically summarized into the following two types: One approach is to control the linear speed of the cable being laid to a constant level to achieve stable tension control. However, upon closer examination, its applicable conditions are quite limited. It is only suitable for situations where the tension increases due to the decrease in linear speed caused by the decrease in the radius of the cable spool as the cable is laid. However, when the span of the cable in the air is large, or when it is constantly swaying and vibrating due to wind, a constant cable linear speed will cause the tension to fluctuate continuously, or even become too high, leading to damage to the cable and hindering the high-quality completion of cable laying and winding. The other approach is to determine the rated tension according to the line design and preset the control tension of the cable before laying. The methods of controlling the tension include: using a drive motor set on the tension cable laying device to maintain constant tension through frequency conversion; and using a motor that applies driving force in conjunction with a motor that applies resistance to maintain constant tension. However, it requires a relatively sophisticated tension monitoring and control system, as well as a tension control execution system, resulting in high costs and hindering the widespread adoption of constant tension cable laying. Moreover, existing tension cable laying devices cannot stop the cable after the motor is powered off, typically resulting in a secondary pull after laying, causing the cable to continue to be released. This affects the control of cable tension after the motor stops. Utility Model Content

[0012] Furthermore, the parking swing arm includes a swing arm pivot, a swing arm body, and a tightening nut.

[0013] Furthermore, the swing arm pivot is disposed on the side of the support frame, one end of the swing arm body is connected to the swing arm pivot, and the other end of the swing arm body is movably connected to the parking ratchet; the tightening nut is respectively connected to one end of the swing arm body and the swing arm pivot.

The parking swing arm is arranged on the inner side of the other support frame, and the parking swing arm is movably connected to the parking ratchet, which is connected to one side of the wire feeding drum. When the power mechanism stops outputting power, causing the wire feeding drum to stop rotating, the user can move the parking swing arm located on the inner side of one of the support frames, so that one end of the parking swing arm abuts against a ratchet tooth in the parking ratchet. At this time, the parking ratchet will be locked and unable to rotate, causing the wire feeding drum connected to one side of the drum to be locked and unable to rotate as well. At this time, the cable pulled out from the wire feeding drum can no longer be released. Thus, even after the power mechanism stops, the released cable and other wires can still maintain a constant tension. Therefore, this tension wire feeding device solves the technical problem of how to improve the wire feeding tension caused by the cable being pulled again after the motor of the wire feeding device stops.

[0024] Please refer to the following: Figures 1 to 4 This utility model discloses a tension wire feeding device comprising: a support frame 1, a wire feeding drum 2, a reduction gear set 3, a parking ratchet 4, a power mechanism 5, and a parking swing arm 6; the wire feeding drum 2 is movably arranged between two support frames 1, the reduction gear set 3 is arranged on one side of the wire feeding drum 2, and the parking ratchet 4 is arranged on the other side of the wire feeding drum 2; the power mechanism 5 is arranged on the outer side of one support frame 1, the power mechanism 5 is poweredly connected to the reduction gear set 3, and the reduction gear set 3 is tractively connected to the wire feeding drum 2; the parking swing arm 6 is arranged on the inner side of the other support frame 1, the parking swing arm 6 is movably connected to the parking ratchet 4, and the parking ratchet 4 is connected to one side of the wire feeding drum 2.

[0025] Specifically, when the tension wire feeding device of this utility model is in operation, the wire feeding drum 2 can rotate between the two support frames 1, and the surface of the wire feeding drum 2 is pre-wound with cables or other wires; when it is necessary to pull the cables or other wires out from the wire feeding drum 2, the power mechanism 5 can output power to the reduction gear set 3, the reduction gear set 3 reduces the rotation speed and increases the output torque, and then transmits the power to the wire feeding drum 2. At this time, the wire feeding drum 2 can feed the wire at a preset speed and maintain a constant tension on the released cables or other wires. Subsequently, when the power mechanism 5 stops outputting power, causing the cable reel 2 to stop rotating, the user can move the parking arm 6 located on the inner side of one of the support frames 1, so that one end of the parking arm 6 abuts against a ratchet tooth in the parking ratchet 4. At this time, the parking ratchet 4 will be locked and unable to rotate, causing the cable reel 2 connected to one side of the cable reel 2 to be locked and unable to rotate at the same time; at this time, the cable pulled out from the cable reel 2 can no longer continue. The cable is released; thus, even after the power mechanism 5 stops, the released cable or other wire can maintain a constant tension; or, the parking arm 6 can be engaged with the parking ratchet 4 at a preset position. In this case, as long as the parking ratchet 4 is rotated in a preset direction, for example, in the direction of the cable release spool 2, the parking arm 6 will not abut against the parking ratchet 4 and prevent the parking ratchet 4 from moving in the opposite direction of the preset direction. Therefore, this tension cable release device solves the technical problem of how to improve the cable tension caused by secondary pulling after the motor of the cable release device stops.

[0026] Furthermore, the wire feeding spool 2 has a spool body 201, a wire guide plate 202, a gear sleeve shaft 203, and a wire feeding rotating shaft 204; the wire guide plate 202 is provided on one side of the spool body 201, and the side of the wire guide plate 202 is connected to the parking ratchet 4; the gear sleeve shaft 203 is provided on the other side of the spool body 201, and the gear sleeve shaft 203 is connected to the reduction gear set 3; the wire feeding rotating shaft 204 is provided in the spool body 201, and the wire feeding rotating shaft 204 is movably connected between the two support frames 1.

[0027] Furthermore, the reduction gear set 3 includes a first gear 301, a second gear 302, a first gear shaft 303, a third gear 304, a fourth gear 305, and a second gear shaft 306; the first gear 301 is connected to the gear sleeve shaft 203, the first gear 301 is meshed with the second gear 302, the second gear 302 is connected to the first gear shaft 303, and the first gear shaft 303 is movably connected between the two support frames 1; the third gear 304 is adjacent to the second gear 302 and connected to the first gear shaft 303, the third gear 304 is meshed with the fourth gear 305, the fourth gear 305 is connected to the second gear shaft 306, the second gear shaft 306 is adjacent to the first gear shaft 303 and movably connected between the two support frames 1, and the power mechanism 5 is driven by the second gear shaft 306.

[0028] Furthermore, the power mechanism 5 includes a motor bracket 501, a drive motor 502, and a coupling 503; the motor bracket 501 is connected to the side of one of the support frames 1, and the drive motor 502 is connected to the motor bracket 501; the coupling 503 connects the drive motor 502 and the second gear shaft 306 respectively.

[0029] Specifically, when the drive motor 502 is powered on and started, its power can be driven to the second gear shaft 306 through the coupling 503. The second gear shaft 306 then drives the fourth gear 305 to rotate. When the fourth gear 305 rotates, it can drive the third gear 304 through meshing transmission. The third gear 304 then drives the first gear shaft 303. When the first gear shaft 303 rotates, it drives the second gear 302. The second gear 302 then drives the first gear 301 through meshing transmission. When the first gear 301 rotates, it can drive the cylinder 201 through the gear sleeve shaft 203, allowing the cylinder 201 to rotate around the unwinding shaft 204. Thus, the cylinder 201 can be used for winding or unwinding. More specifically, by having different gear ratios among the first gear 301, second gear 302, third gear 304, and fourth gear 305, the functions of deceleration and torque increase can be achieved.

[0030] Furthermore, the parking swing arm 6 has a swing arm pivot 601, a swing arm body 602, and a tightening nut 603; the swing arm pivot 601 is disposed on the side of the support frame 1, one end of the swing arm body 602 is connected to the swing arm pivot 601, and the other end of the swing arm body 602 is movably connected to the parking ratchet 4; the tightening nut 603 connects one end of the swing arm body 602 to the swing arm pivot 601. Specifically, when the user loosens the nut 603, the swing arm body 602 can be swung along its connection end with the swing arm shaft 601 so that the other end of the swing arm body 602 can be engaged with one of the ratchet teeth of the parking ratchet 4. At this time, the parking ratchet 4 is locked. The user then tightens the nut 603 to fix the position of the swing arm body 602, thus parking the cable reel 2 stably and preventing the cable or other wires in the cable reel 2 from being pulled after the power mechanism 5 stops. When it is necessary to release the parking swing arm 6 from the cable reel 2, simply loosen the nut 603 again, move the swing arm body 602 away from the parking ratchet 4, and then tighten the nut 603 again to fix the position of the swing arm body 602. Because the parking ratchet 4 has a reversible structure, under normal circumstances, it is only necessary to loosen the nut 603 so that the swing arm body 602 can swing freely around the connection between it and the swing arm pivot 601. At this time, the parking ratchet 4 will not be jammed by the swing arm body 602 as long as it rotates in the preset rotation direction.

[0031] Furthermore, the side of the wire feeding drum 2 is also provided with an active braking structure 7, which has a brake swing shaft 701, a brake handle 702, and a brake tensioning part 703; the brake swing shaft 701 is connected between the two support frames 1, one end of the brake handle 702 is movably connected to the brake swing shaft 701, the brake handle 702 is connected to the brake tensioning part 703, and the brake tensioning part 703 is coiled and connected to the gear sleeve shaft 203 adjacent to the first gear 301. Specifically, during the rotation of the cable reel 2, if it needs to be stopped quickly, for example, after the cable reel 2 has released a preset length of cable, the user can pull the brake handle 702 to cause the brake tensioning part 703 to move. The brake tensioning part 703 is partially coiled in a disc shape around the gear sleeve shaft 203 and is arranged adjacent to the first gear 301. One end of the brake tensioning part 703 is connected to the side of the brake handle 702. When the brake handle 702 is pulled, the diameter of the disc-shaped part of the brake tensioning part 703 is reduced due to the pulling of one end, so that its inner side abuts against the surface of the gear sleeve shaft 203. Through the mutual friction between the two, the gear sleeve shaft 203 is decelerated to the point of stopping rotation.

[0032] In summary, the tension wire feeding device of this utility model is provided with a support frame 1, a wire feeding drum 2, a reduction gear set 3, a parking ratchet 4, a power mechanism 5, and a parking swing arm 6. The wire feeding drum 2 is movably arranged between the two support frames 1. The reduction gear set 3 is arranged on one side of the wire feeding drum 2, and the parking ratchet 4 is arranged on the other side of the wire feeding drum 2. The power mechanism 5 is arranged on the outer side of one support frame 1, and the power mechanism 5 is poweredly connected to the reduction gear set 3. The reduction gear set 3 is drivenly connected to the wire feeding drum 2. The parking swing arm 6 is arranged on the inner side of the other support frame 1. The parking swing arm 6 is movably connected to the parking ratchet 4, and the parking ratchet 4 is connected to one side of the wire feeding drum 2. When the power mechanism 5 stops outputting power, causing the wire feeding drum 2 to stop rotating, the user can move the parking swing arm 6 located on the inner side of one of the support frames 1, so that one end of the parking swing arm 6 abuts against a ratchet tooth in the parking ratchet 4. At this time, the parking ratchet 4 will be locked and unable to rotate, and the wire feeding drum 2 connected to one side of the wire feeding drum 2 will also be locked and unable to rotate. At this time, the cable pulled out from the wire feeding drum 2 can no longer be released. Thus, even after the power mechanism 5 stops, the released cable and other wires can still maintain a constant tension. Therefore, this tension wire feeding device solves the technical problem of how to improve the wire tension caused by the cable being pulled again after the motor of the wire feeding device stops.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
