Description
Technical Field
[0001] This utility model relates to the field of power engineering laying and setting technology, and in particular to a structure of a laying device for power transmission engineering. Background Technology
[0002] In the construction of power transmission lines, the wire laying operation is a crucial step in the orderly release of conductors from the reel and their guidance to a fixed position on the tower. The wire laying device, as the core equipment for supporting, guiding, and controlling conductor tension, plays a vital role throughout the entire construction process.
[0003] However, traditional cable laying devices mostly employ integral welding or bolt-fixed structures, which present problems such as inconvenient transportation, complex installation, and difficulty in disassembly. This is especially evident when the cable reel is large and heavy, further increasing the difficulty of handling and operation, making them unsuitable for mountainous, hilly, or other areas with limited access. Furthermore, fixed-structure devices are typically only compatible with specific reel sizes and cannot be adjusted according to reel dimensions, limiting their versatility across different voltage levels and construction environments, leading to duplicate equipment purchases and resource waste.
[0004] Therefore, it is necessary to design a wire-laying device structure for power transmission engineering. Utility Model Content

[0021] Example: A wire-laying device structure for power transmission engineering, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a base 1, a coil support rod 2, a first gear 3, a second gear 4, a motor 5, a mounting plate 6, locking posts 7, a first elastic element 8, and an adjustment mechanism. The coil support rod 2 is rotatably mounted on the upper part of the base 1. The first gear 3 is connected to the left side of the coil support rod 2, and the second gear 4 is rotatably connected to the left side of the base 1. The second gear 4 meshes with the first gear 3. The motor 5 is bolted to the left side of the base 1, and the output shaft of the motor 5 is connected to the second gear 4. The mounting plate 6 is located on the right side of the coil support rod 2 and is fitted onto the coil support rod 2. The coil support rod 2 has two locking slots. Locking posts 7 are slidably connected to both the upper and lower sides of the mounting plate 6. The locking posts 7 are locked into the locking slots, and the first elastic element 8 is connected between the locking posts 7 and the mounting plate 6. An adjustment mechanism is provided between the coil support rod 2 and the base 1.
[0022] like Figure 1 , Figure 2 and Figure 3As shown, the adjustment mechanism includes an adjustment block 9, a locking block 10, a locking screw 11, a bidirectional screw 12, and a knob 13. The adjustment blocks 9 are slidably connected to the lower left and right sides of the base 1. The adjustment blocks 9 are located on the lower side of the spool support rod 2. The bidirectional screw 12 is rotatably connected to the lower part of the base 1. The two adjustment blocks 9 are threadedly engaged with the bidirectional screw 12. The knobs 13 are fixedly connected to both sides of the bidirectional screw 12. The locking blocks 10 are rotatably connected to the upper part of the adjustment blocks 9. The locking blocks 10 are located on the upper side of the spool support rod 2. Both the locking blocks 10 and the adjustment blocks 9 are slidably connected to the spool support rod 2. The locking blocks 10 and the adjustment blocks 9 on the same side are threadedly connected to the locking screw 11. When the adjustment blocks 9 and the locking blocks 10 are closed, they are in a circular shape.
[0023] like Figure 1 and Figure 4 As shown, it also includes casters 14, support feet 15, first adjusting screws 16, and sleeves 17. Multiple casters 14 are installed on the lower part of the base 1. Support feet 15 are slidably connected to the front and rear sides of the lower part of the base 1. In the initial state, the horizontal position of the support feet 15 is higher than the height of the casters 14. The first adjusting screws 16 are slidably connected to the front and rear sides of the lower part of the base 1. The first adjusting screws 16 are all connected to the support feet 15. Sleeves 17 are rotatably connected to the front and rear sides of the lower part of the base 1. The sleeves 17 are all threadedly connected to the first adjusting screws 16.
[0024] like Figure 1 , Figure 4 and Figure 5 As shown, the system also includes a connecting frame 18, a guide pulley 19, a second adjusting screw 20, an adjusting plate 21, and a second elastic element 22. The connecting frame 18 is fixedly connected to the lower front side of the base 1. The guide pulley 19 is rotatably connected to the upper part of the connecting frame 18. The guide pulley 19 is made of aluminum alloy, which is high in strength, lightweight, corrosion-resistant, and has a long service life. It is suitable for cable-laying equipment requiring long-term support and has a stable and reliable structure. The second adjusting screw 20 is rotatably connected to the lower part of the connecting frame 18. Adjusting plates 21 are provided on both the left and right sides of the lower part of the connecting frame 18. The left adjusting plate 21 is slidably connected to the second adjusting screw 20, and the right adjusting plate 21 is threadedly connected to the second adjusting screw 20. A second elastic element 22 is connected between the left adjusting plate 21 and the connecting frame 18. The second elastic element 22 is initially compressed.
[0025] like Figure 1 As shown, it also includes a handle 101. The handle 101 is fixed to the right side of the base 1 and is used in conjunction with the casters 14 to improve the convenience of the equipment.
[0026] In actual use, the operator pushes the device to the construction site using the handle 101 and moves it flexibly using the casters 14 installed on the bottom of the base. Then, the operator rotates the sleeve 17 to drive the first adjusting screw 16 to rotate, causing the support feet 15 to extend downward and contact the ground, thereby providing stable support and fixing for the device, preventing the equipment from shaking or tilting due to uneven ground or other external factors, and improving the safety and stability during operation.
[0027] Next, the reel needs to be installed. Specifically, the operator first pulls the two locking posts 7 on the mounting plate 6 outwards, stretching the first elastic element 8 and releasing the locking state between the mounting plate 6 and the reel support rod 2. Then, the mounting plate 6 is removed from the reel support rod 2. Next, the operator unscrews the locking screw 11 connecting the adjusting block 9 and the locking block 10, and rotates to open the locking block 10, releasing the constraint on the reel support rod 2. At this time, the reel support rod 2 can be removed from the base 1 and the adjusting block 9. During the removal process, the first gear 3 on it will disengage from the second gear 4.
[0028] Next, the operator inserts the reel of wire to be laid onto the reel support rod 2, and simultaneously places the reel support rod 2 back onto the base 1 and adjusting block 9. The mounting plate 6 is then installed and reset: the first elastic element 8 automatically engages the locking pin 7 into the slot on the reel support rod 2, preventing the reel support rod 2 from shifting to the left during rotation on the base 1 and adjusting block 9. Subsequently, the locking block 10 is closed, and the locking screw 11 is tightened to further secure the reel support rod 2. This design significantly improves the efficiency of reel loading and unloading, reduces manual assistance time, and is suitable for construction scenarios requiring frequent reel replacement. During this process, it is also necessary to ensure that the first gear 3 and the second gear 4 re-engage to provide the power transmission foundation for subsequent wire laying operations.
[0029] Furthermore, operators can adjust the two-way screw 12 to move the adjusting blocks 9 on both sides closer or further away, depending on the length of the reel, to accommodate reels of different sizes and specifications, thus improving the versatility and adaptability of the device. After installation, the operator starts the motor 5, driving the second gear 4 to rotate, which in turn drives the first gear 3 to rotate synchronously, achieving uniform rotation of the reel support rod 2 and the mounting plate 6 as a whole, ensuring smooth wire release. During the wire release process, the guide pulley 19 guides the wire, preventing it from shifting or wearing during operation. Simultaneously, the operator can rotate the second adjusting screw 20 to dynamically adjust the distance between the adjusting plates 21 on both sides, thereby adjusting the lateral position of the guide pulley 19 to adapt to different wire release paths and directions. During this process, the adjusting plates 21 apply appropriate clamping force to the guide pulley 19 under the action of the second elastic element 22, ensuring the stability of the wire's running path. Finally, after construction is completed, the operator can use the handle 101 to transfer the device to the next work point, or disassemble it as needed and transport it to other areas, further improving the equipment's on-site applicability and construction efficiency.
