Description

Technical Field

[0001] This utility model relates to the field of cable laying device technology, specifically an anti-tangling cable laying device for power construction. Background Technology

[0002] Power construction is a crucial link in ensuring the construction and maintenance of power systems. It encompasses multiple tasks such as line erection, equipment installation, and wire laying, and is directly related to the safety and stability of power transmission. As an important tool in power construction, the cable laying device is mainly used in the process of erecting and laying conductors. Through its mechanical structure, it enables the smooth release of cables, effectively reducing cable damage during laying, improving construction efficiency, and ensuring that power line laying meets the specifications. It is an indispensable auxiliary equipment in power construction.

[0003] Currently, during the power line laying process, when the wire reel rotates to release the wire, the uncontrollable rotation often results in excessive wire release. As a result, the wires on the surface of the reel become loosely wrapped around the reel, which not only disrupts the original neat wrapping state but also easily causes the wires to entangle with each other, hindering subsequent construction operations. To address this, we propose an anti-entanglement power line laying device. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tangling power construction wire laying device. This device effectively controls the rotation of the wire reel during wire laying to prevent excessive wire release and loose winding on the reel's surface, thus avoiding the original neat winding state and facilitating subsequent power construction. This solves the problem that in current power construction wire laying processes, the uncontrollable rotation of the wire reel often results in excessive wire release, causing the wire on the reel's surface to loosely wind around the reel, disrupting the original neat winding state and easily leading to wire tangling, hindering subsequent construction operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-tangling power construction wire laying device, comprising a wire laying frame, wherein rotating shafts are rotatably mounted on both sides of the inner wall of the wire laying frame near the rear surface, a wire laying shaft is provided between the two rotating shafts, and the ends of the two rotating shafts are respectively connected to the two ends of the wire laying shaft; a connecting rod is provided inside the wire laying frame near the front surface, a lower guide wheel is rotatably mounted on the outer surface of the connecting rod, rotating arms are fixedly connected to both ends of the connecting rod, and the ends of the two rotating arms are respectively located below the two rotating shafts; a connecting shaft is fixedly connected to the outer sides of the two rotating arms, and the ends of the two connecting shafts are respectively rotatably connected to both sides of the inner wall of the wire laying frame; a torsion spring is wound around the outer surface of the two rotating arms; and an upper guide wheel is rotatably mounted inside the wire laying frame above the lower guide wheel.

[0006] Preferably, friction rings are fixedly sleeved on the outer surfaces of both rotating shafts, and friction blocks are fixedly installed on the lower surfaces of both rotating arms near their ends. After the rotating arms rotate under the action of the torsion spring, the friction blocks and friction rings come into contact, which increases the frictional braking force on the rotation of the rotating shafts and effectively controls the rotation of the rotating shafts and the wire reel.

[0007] Preferably, a guide tube is fixedly connected to the bottom of the inner wall of the wire feeding frame near the lower guide wheel via a column, and the guide tube is located between the lower guide wheel and the wire feeding shaft. Both ends of the guide tube are fixedly connected to tapered tubes. The wire released by the wire reel when it rotates passes through the tapered tubes and the guide tubes and enters the interior of the lower guide wheel, thereby serving as a guide for the wire.

[0008] Preferably, both the guide tube and the inner wall of the tapered tube are provided with a lubricating coating. The lubricating coating is a solid lubricating film, such as graphite, molybdenum disulfide, polytetrafluoroethylene, etc., which can reduce the coefficient of friction and improve the surface lubricity, effectively preventing wear on the surface of the wire.

[0009] Preferably, limit rings are movably sleeved on the outer surface of the wire feeding shaft near both ends. The outer surface of each limit ring is provided with a threaded hole, and a screw is movably inserted into each of the two threaded holes. By turning the screw so that its end contacts the outer surface of the wire feeding shaft, the limit ring can be fixed. The two limit rings located on both sides of the wire reel play a role in limiting and fixing the wire reel.

[0010] Preferably, each of the two rotating shafts has an insertion block at its end. A connecting sleeve is slidably fitted onto the outer surface of the pay-off shaft near both ends. A helical spring is wound around the outer surface of the pay-off shaft near the inner side of each connecting sleeve. Moving the two connecting sleeves in opposite directions allows the pay-off shaft to be placed between the two rotating shafts, with each end of the pay-off shaft close to the two insertion blocks. Releasing the two connecting sleeves releases the compressed helical springs, pushing the two connecting sleeves to slide, allowing the insertion blocks to enter the connecting sleeves, thus completing the installation of the pay-off shaft. For disassembly, moving the two connecting sleeves in opposite directions allows the insertion blocks to exit from the connecting sleeves, enabling the pay-off shaft to be removed. This facilitates the installation and removal of the pay-off shaft and the replacement of the wire reel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a wire-feeding frame, connecting rod, rotating arm, connecting shaft, torsion spring, wire-feeding shaft, rotating shaft, upper guide wheel, and lower guide wheel, effectively controls the rotation of the wire reel during wire feeding, preventing excessive wire release and loose winding on the surface of the wire reel, thus disrupting the original neat winding state and avoiding tangling between wires. This facilitates subsequent power construction. The wire reel is fitted onto the outer surface of the wire-feeding shaft. The wire released from the wire reel passes sequentially through the lower and upper guide wheels. The upper guide wheel lifts and guides the wire, and the wire at the upper and lower guide wheels forms a Z-shape. The elasticity of the torsion spring causes the connecting shaft to drive the rotating arm to rotate, and... The contact between the outer surfaces of the rotating shaft and the wire feeding shaft restricts their rotation, thus limiting the rotation of the wire reel and the release of the wire. When the wire is pulled to tension the wire between the upper guide wheel and the wire reel, the lower guide wheel is forced to rotate around the connecting shaft, causing the rotating arm and the rotating shaft to separate. This allows the wire reel to rotate and release the wire. Therefore, the wire reel can only rotate and release the wire when the wire is pulled and the wire between the upper guide wheel and the wire reel is tensioned. When the wire between the upper guide wheel and the wire reel is loose, the rotation of the wire reel is restricted, thus effectively controlling the rotation of the wire reel and the wire feeding.

[0013] 2. By setting up a guide tube and a tapered tube, the wire released by the rotating wire reel passes through the tapered tube and the guide tube and enters the lower guide wheel, thus guiding the wire.

[0014] 3. The lubricating coating of this utility model reduces the coefficient of friction and improves surface lubrication when the wire passes through the tapered tube and the guide tube, effectively preventing wear on the surface of the wire.

[0015] 4. This utility model, by setting a helical spring, connecting sleeves, and inserts, achieves the effect of facilitating the disassembly and assembly of the pay-off spool and the replacement of the wire reel. The two connecting sleeves are moved in opposite directions so that the pay-off spool can be placed between the two rotating shafts, with both ends of the pay-off spool close to the two inserts. After the two connecting sleeves are released, the compressed helical spring is released and pushes the two connecting sleeves to slide, and the inserts enter the inside of the connecting sleeves, thus completing the installation of the pay-off spool. When disassembling, the two connecting sleeves are moved in opposite directions so that the inserts are withdrawn from the inside of the connecting sleeves, and the pay-off spool can be removed.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the present invention proposes an anti-tangling power construction wire laying device, including a wire laying frame 1. The wire laying frame 1 is U-shaped in front view. Rotating shafts 7 are rotatably installed on both sides of the inner wall of the wire laying frame 1 near the rear surface. A wire laying shaft 6 is arranged between the two rotating shafts 7, and the ends of the two rotating shafts 7 are respectively connected to the two ends of the wire laying shaft 6. A wire reel with wire wound on it is sleeved on the outer surface of the wire laying shaft 6. Limiting rings 17 are movably sleeved on the outer surface of the wire laying shaft 6 near both ends. The outer surface of the two limiting rings 17 is provided with threaded holes 18, and screws 19 are movably inserted into the two threaded holes 18. By turning the screws 19 so that their ends contact the outer surface of the wire laying shaft 6, the limiting rings 17 can be fixed. The two limiting rings 17 located on both sides of the wire reel play a role in limiting and fixing the wire reel.

[0025] A connecting rod 3 is located inside the wire feeder 1 near the front surface. A lower guide wheel 4 is rotatably mounted on the outer surface of the connecting rod 3. Both ends of the connecting rod 3 are fixedly connected to rotating arms 8, and the ends of the two rotating arms 8 are located below the two rotating shafts 7, respectively. A connecting shaft 11 is fixedly connected to the outer side of the two rotating arms 8, and the ends of the two connecting shafts 11 are rotatably connected to the two sides of the inner wall of the wire feeder 1, respectively. A torsion spring 10 is wound around the outer surface of the two rotating arms 8, and the two ends of the torsion spring 10 are fixedly connected to the outer surface of the connecting shaft 11 and the inner wall of the wire feeder 1, respectively. The elastic torsional force of the torsion spring 10 causes the connecting shaft 11 to drive the rotating arms 8 to rotate. Friction rings 21 are fixedly sleeved on the outer surface of the two rotating shafts 7. Friction blocks 9 are fixedly mounted on the lower surface of the two rotating arms 8 near the end. After the rotating arms 8 rotate under the action of the torsion springs 10, the friction blocks 9 and the friction rings 21 come into contact, which plays a friction braking role on the rotating shafts 7, effectively controlling the rotation of the rotating shafts 7 and the wire reel. An upper guide wheel 2 is rotatably mounted inside the wire feeder 1 above the lower guide wheel 4.

[0026] In use, the wire reel is fitted onto the outer surface of the pay-off shaft 6. The wire released from the wire reel passes sequentially through the lower guide wheel 4 and the upper guide wheel 2. The upper guide wheel 2 lifts and guides the wire, and the wires at the upper guide wheel 2 and the lower guide wheel 4 form a Z-shape. The elasticity of the torsion spring 10 causes the connecting shaft 11 to drive the rotating arm 8 to rotate, bringing the friction block 9 and the friction ring 21 into contact. The friction between them restricts the rotation of the rotating shaft 7 and the pay-off shaft 6, thereby limiting the rotation of the wire reel and the release of the wire. When the wire is pulled to tension the wire between the upper guide wheel 2 and the wire reel, it forces the lower guide wheel to... Wheel 4 rotates around shaft 11, causing arm 8 to rotate and friction block 9 and friction ring 21 to separate. This allows the wire reel to rotate and release the wire. Therefore, the wire reel can only rotate and release the wire when the wire is pulled and the wire between upper guide wheel 2 and wire reel is taut. When the wire between upper guide wheel 2 and wire reel is loose, the rotation of wire reel is restricted. This effectively controls the rotation and wire release of wire reel, preventing excessive wire release and loose winding on the surface of wire reel, which would disrupt the original neat winding state and prevent the wires from tangling together, thus facilitating subsequent power construction. Example 2

[0027] like Figure 1 and Figure 3As shown, the present invention proposes an anti-tangling power construction wire laying device. Compared with Embodiment 1, this embodiment further includes a guide tube 5 fixedly connected to the bottom of the inner wall of the laying frame 1 near the lower conductor wheel 4 via a column 14. The guide tube 5 is located between the lower conductor wheel 4 and the laying shaft 6. Both ends of the guide tube 5 are fixedly connected to tapered tubes 12. The inner walls of the guide tube 5 and the tapered tube 12 are provided with a lubricating coating 13. The lubricating coating 13 is a solid lubricating film, such as graphite, molybdenum disulfide, polytetrafluoroethylene, etc., which can reduce the coefficient of friction and improve the surface lubricity, effectively preventing wear on the surface of the wire.

[0028] In this embodiment, the wire released by the rotating wire reel passes through the tapered tube 12 and the guide tube 5 and enters the lower guide wheel 4, which serves to guide the wire. Example 3

[0029] like Figure 1 , Figure 4 and Figure 6 As shown, the present invention proposes an anti-tangling power construction wire laying device. Compared with the first embodiment, this embodiment also includes two rotating shafts 7, each with an insert block 20 at its end. The outer surface of the wire laying shaft 6 is slidably sleeved with connecting sleeves 16 near both ends. The outer surface of the wire laying shaft 6 is wound with helical springs 15 near the inner side of the two connecting sleeves 16, and the two ends of the helical springs 15 are respectively fixedly connected to the connecting sleeves 16 and the outer surface of the wire laying shaft 6.

[0030] In this embodiment, the two connecting sleeves 16 are moved in opposite directions so that the pay-off shaft 6 can be placed between the two rotating shafts 7, and the two ends of the pay-off shaft 6 are close to the two inserts 20 respectively. After the two connecting sleeves 16 are released, the compressed helical spring 15 is released and pushes the two connecting sleeves 16 to slide, and the inserts 20 enter the interior of the connecting sleeves 16, thus completing the installation of the pay-off shaft 6. When disassembling, the two connecting sleeves 16 are moved in opposite directions so that the inserts 20 are withdrawn from the interior of the connecting sleeves 16, and the pay-off shaft 6 can be disassembled, which facilitates the disassembly and assembly of the pay-off shaft 6 and the replacement of the wire reel.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
