Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically, to a power cable laying device. Background Technology

[0002] During power construction, cables need to be laid, and this requires installing cable reels wrapped with cable onto a cable-laying device. Existing cable-laying devices, due to the weight of the cable reels, require the use of other equipment to lift them before installation. This method not only increases construction costs but also limits the installation process and is inconvenient due to space constraints. Furthermore, existing cable-laying devices typically involve pulling the cable to rotate the reel, allowing it to rotate freely. During construction, unexpected external forces can cause unnecessary rotation, interfering with the power construction and potentially pulling on the cable, posing a safety hazard.

[0029] Please see Figures 1-5 A power cable laying device includes a base 1, a bracket 2 fixedly mounted on the base 1, a lifting seat 3 slidably connected to the bracket 2 via a track structure, a plurality of rotating rollers 4 rotatably mounted on the lifting seat 3, rotating rods 5 movably mounted on the plurality of rotating rollers 4, a cable reel 6 fixedly mounted between two rotating rods 5, a drive chamber 7 and two moving slots 8 provided inside the base 1, a drive motor 9 fixedly mounted on one side of the base 1, the drive end of the drive motor 9 extending into the drive chamber 7 and fixedly mounted on a drive rod 10, the drive rod 10 being rotatably connected to the drive chamber 7, two drive bevel gears 11 fixedly mounted on the drive rod 10, a bidirectional screw 12 rotatably mounted inside the moving slots 8, one end of the bidirectional screw 12 extending into the drive chamber 7 and fixedly mounted on a driven bevel gear 13, two drive seats 14 threadedly mounted on the bidirectional screw 12, a support rod 15 hinged between each drive seat 14 and the lifting seat 3, and two limiting slots 16 provided on the base 1.

[0030] In this embodiment, when it is necessary to install the cable reel 6 with the cable wound on it, the cable reel 6 is pushed, causing it to roll along the limiting groove 16 and move onto the base 1. The cable reel 6 drives the two rotating rods 5 to rotate and move simultaneously, moving the rotating rods 5 above the lifting seat 3. The drive motor 9 is then started, causing the drive rod 10 to rotate. The drive rod 10 drives the two drive bevel gears 11 to rotate. Since the drive bevel gears 11 are meshed with the driven bevel gears 13, the driven bevel gears 13 rotate. The driven bevel gears 13 drive the bidirectional screw 12 to rotate. Because the bidirectional screw 12 has two threaded areas in opposite directions, the two drive seats 1... 4. Move along the moving groove 8 to the adjacent direction. The drive seat 14 drives the support rod 15 to rotate. While the support rod 15 rotates, it pushes the lifting seat 3 upward, so that the lifting seat 3 moves upward along the sliding connection with the bracket 2. During the movement of the lifting seat 3, it will drive multiple rotating rollers 4 to move, so that the rotating rod 5 is placed on the upper end of multiple rotating rollers 4. As the lifting seat 3 continues to move, it drives the rotating rollers 4, rotating rod 5 and cable reel 6 to move. At this time, the cable reel 6 separates from the base 1 and the limiting groove 16, and the installation of the cable reel 6 can be completed. Pull the cable. Under the pull of the cable, the cable reel 6 drives the rotating rod 5 to rotate, and multiple rotating rollers 4 rotate, thereby laying out the cable.

[0031] Please see Figures 1-5 As one embodiment for fixing the cable reel 6: two limiting shells 17 are movably provided on the upper end of the cable reel 6. An anti-slip pad 18 is fixedly provided inside each limiting shell 17. A lifting rod 19 is installed on the upper end of the limiting shell 17. The lifting rod 19 is movably connected to the bracket 2. A push plate 20 is fixedly provided through the bracket 2 at the upper end of each lifting rod 19. A spring 21 is movably sleeved on the outside of the lifting rod 19. A dual-axis motor 22 is fixedly provided on the bracket 2. A rotating shaft 23 is fixedly provided on each of the two drive ends of the dual-axis motor 22. One end of the rotating shaft 23 is rotatably connected to the bracket 2. A convex wheel 24 is fixedly provided on each rotating shaft 23. A limiting rod 25 is movably provided on the lower end of the lifting rod 19. A limiting hole 26 that cooperates with the limiting rod 25 is provided on the lifting rod 19. A drive ring 27 is rotatably provided on the lower end of the lifting rod 19. A fixing seat 28 is threadedly connected inside the drive ring 27. The upper end of the fixing seat 28 is fixedly connected to the limiting rod 25. The lower end of the fixing seat 28 is fixedly connected to the limiting shell 17.

[0032] More specifically, when cable laying is not required, the dual-axis motor 22 is started, driving two rotating shafts 23 to rotate. The rotating shafts 23 drive the convex wheel 24 to rotate. As the convex wheel 24 rotates, its protruding part pushes the push plate 20 downward. The push plate 20 drives the lifting rod 19 to move downward, compressing the spring 21. The lifting rod 19 drives the limiting shell 17 to move, and the limiting shell 17 drives the anti-slip pad 18 to move, so that the anti-slip pad 18 comes into contact with the cable reel 6 and is limited and fixed by friction. When cable laying is required, the dual-axis motor 22 is started, driving two rotating shafts 23 to rotate. The rotating shafts 23 drive the convex wheel 24 to rotate, so that the protruding part of the convex wheel 24 separates from the push plate 20. Under the push of the spring 21, the push plate 20 drives the lifting rod 19, the installed limiting shell 17, and the anti-slip pad 18 to move back to their original positions. At this time, the anti-slip pad 18 separates from the cable reel 6, releasing the limitation and fixation of the cable reel 6. When the limiting shell 17 and the anti-slip pad 18 are damaged, rotate the drive ring 27 to separate the drive ring 27 from the fixed seat 28, pull the limiting shell 17 down, so that the limiting shell 17 drives the limiting rod 25 to separate from the limiting hole 26 through the fixed seat 28, and the limiting shell 17 and the anti-slip pad 18 can be removed. The replacement limiting shell 17 and anti-slip pad 18 can be installed by using the reverse operation.

[0033] In summary, during the use or operation of the overall equipment: when it is necessary to install the cable reel 6 with the cable wound on it, push the cable reel 6 so that it rolls along the limiting groove 16 and moves onto the base 1. The cable reel 6 drives the two rotating rods 5 to rotate and move simultaneously, moving the rotating rods 5 above the lifting seat 3. Start the drive motor 9, which drives the drive rod 10 to rotate. The drive rod 10 drives the two drive bevel gears 11 to rotate. Since the drive bevel gears 11 are meshed with the driven bevel gears 13, the driven bevel gears 13 rotate. The driven bevel gears 13 drive the bidirectional screw 12 to rotate. Since the bidirectional screw 12 has two threaded areas with opposite directions, the two... The drive seat 14 moves along the moving groove 8 in the adjacent direction. The drive seat 14 drives the support rod 15 to rotate. While the support rod 15 rotates, it pushes the lifting seat 3 upward, so that the lifting seat 3 moves upward along the sliding connection with the bracket 2. During the movement of the lifting seat 3, it will drive multiple rotating rollers 4 to move, so that the rotating rod 5 is placed on the upper end of the multiple rotating rollers 4. As the lifting seat 3 continues to move, it drives the rotating rollers 4, the rotating rod 5 and the cable reel 6 to move. At this time, the cable reel 6 separates from the base 1 and the limiting groove 16, and the installation of the cable reel 6 can be completed. Pull the cable, and under the pull of the cable, the cable reel 6 drives the rotating rod 5 to rotate, and the multiple rotating rollers 4 rotate, thereby releasing the cable.

[0034] When cable laying is not required, the dual-axis motor 22 is started, driving two rotating shafts 23 to rotate. The rotating shafts 23 drive the convex wheel 24 to rotate. As the convex wheel 24 rotates, its protruding part pushes the push plate 20 downward. The push plate 20 drives the lifting rod 19 to move downward, compressing the spring 21. The lifting rod 19 drives the limiting shell 17 to move, and the limiting shell 17 drives the anti-slip pad 18 to move, so that the anti-slip pad 18 comes into contact with the cable reel 6 and is limited and fixed by friction. When cable laying is required, the dual-axis motor 22 is started, driving two rotating shafts 23 to rotate. The rotating shafts 23 drive the convex wheel 24 to rotate, so that the protruding part of the convex wheel 24 separates from the push plate 20. Under the push of the spring 21, the push plate 20 drives the lifting rod 19, the installed limiting shell 17, and the anti-slip pad 18 to move back to their original positions. At this time, the anti-slip pad 18 separates from the cable reel 6, releasing the limitation and fixation of the cable reel 6. When the limiting shell 17 and the anti-slip pad 18 are damaged, rotate the drive ring 27 to separate the drive ring 27 from the fixed seat 28, pull the limiting shell 17 down, so that the limiting shell 17 drives the limiting rod 25 to separate from the limiting hole 26 through the fixed seat 28, and the limiting shell 17 and the anti-slip pad 18 can be removed. The replacement limiting shell 17 and anti-slip pad 18 can be installed by using the reverse operation.
