Description

Technical Field

[0001] This utility model relates to the field of cable or wire installation technology, and in particular to a cable lifting device. Background Technology

[0002] Cable transmission refers to the technology of transmitting signals and energy through cables. Thanks to the development of modern digital mobile communication technology, cable transmission has been continuously improving and upgrading in the past few years. Chinese utility model patent, authorized announcement number "CN221126750U", discloses a cable lifting device. This utility model provides a cable lifting device in which the lifting platform and the first and second side frames of the main frame are slidably connected, and a driving device is provided to drive the lifting platform to slide, so that the lifting platform lifts the cable along the height direction of the first and second side frames, realizing the change of the height position of the cable. The process is fully automatic, without the need for manpower, and saves time.

[0003] While the above-mentioned technical solution can automatically lift the cable without the need for manpower, after the cable is lifted to the designated height, it is still necessary to manually push the cable on the lifting part directly onto the cable rack. Because the cable is heavy and long, it takes a lot of physical effort to place the cable onto the cable rack. Furthermore, if the cable is not placed on the cable rack at the same time, it may slip off the cable rack, thus affecting the lifting effect. Therefore, we propose a cable lifting device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a cable lifting device that can automatically lift cables without the need for manpower. However, after the cable is lifted to a specified uniform height, it is still necessary to manually push the cable on the lifting part directly onto the cable rack. Because the cable is heavy and long, it takes a lot of physical effort to place the cable onto the cable rack. Furthermore, if the cable is not placed on the cable rack at the same time, it may slip off the cable rack, thus affecting the lifting effect of the cable.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a cable lifting device, comprising:

[0027] The support frame 2, the lifting frame 3, and the fixed base 1 are all fixedly connected to the top of the fixed base 1 by bolts.

[0028] The lifting structure is located on the lifting frame 3;

[0029] The lifting structure includes two fixed plates 13, a rotating shaft 11, two threaded rods 14, a drive motor 8, two bevel gear rings 16, and two bevel gears 17. Two lifting grooves 4 are opened on the side of the lifting frame 3 away from the support frame 2. Transmission grooves 15 are opened on both sides of the lifting frame 3. The two threaded rods 14 are rotatably connected to the interior of the corresponding lifting grooves 4. One end of the two threaded rods 14 rotatably extends into the interior of the corresponding transmission grooves 15 and is fixedly connected to the corresponding bevel gears 17.

[0030] Two fixed plates 13 are fixedly connected to the top of the fixed base 1. The rotating shaft 11 is rotatably connected to the opposite surfaces of the two fixed plates 13. The drive motor 8 is fixedly installed on the corresponding fixed plate 13. The output end of the drive motor 8 rotates through the corresponding fixed plate 13 and is fixedly connected to the rotating shaft 11. Two bevel gear rings 16 are fixedly sleeved on the outer surface of the rotating shaft 11. The two bevel gear rings 16 are meshed with the corresponding bevel gears 17. The end of the rotating shaft 11 away from the drive motor 8 passes through two transmission grooves 15 in sequence. The two bevel gear rings 16 and the corresponding bevel gears 17 are meshed with each other in the corresponding transmission grooves 15.

[0031] The lifting structure also includes two sliding blocks 12, two lifting plates 9, two cable placement racks 10 and two electric telescopic rods 19. The two sliding blocks 12 are threaded onto the outer surface of the corresponding threaded rods 14. The two sliding blocks 12 are slidably connected to the inside of the corresponding lifting grooves 4. The two lifting plates 9 are fixedly connected to one side of the corresponding sliding blocks 12. The two lifting plates 9 are both "L" shaped structures. The bottom of the two lifting plates 9 is provided with a rotating groove 18.

[0032] Support plates 20 are fixedly connected to both sides of the two lifting plates 9. The two cable placement racks 10 are rotatably connected to the opposite surfaces of the two support plates 20. The interior of the two cable placement racks 10 is a "C" shaped structure. The two electric telescopic rods 19 are rotatably connected to the interior of the corresponding rotating grooves 18. The telescopic ends of the two electric telescopic rods 19 are rotatably connected to the bottom of the corresponding cable placement rack 10.

[0033] The support frame 2 and the lifting frame 3 are internally rotatably connected by a rotating column 5. A support cylinder 6 is fixedly connected to the outer surface of the rotating column 5. A threaded column 7 is internally threadedly connected to the support cylinder 6.

[0034] Furthermore, when using the device to lift the cable, the drive motor 8 is started, which drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the two bevel gear rings 16 to rotate synchronously. Through the meshing of the bevel gear 17, the bevel gear ring 16 can drive the corresponding threaded rod 14 to rotate through the corresponding bevel gear 17. When the threaded rod 14 rotates, the threaded sliding block 12 is guided inside the lifting groove 4 and rises and falls vertically along the inner wall of the lifting groove 4. The rise of the sliding block 12 can drive the corresponding lifting plate 9 and the cable placement rack 10 to move synchronously, thereby realizing the vertical lifting of the cable.

[0035] Once the cable is raised to the designated height, the electric telescopic rod 19 is activated. The extension and retraction of the electric telescopic rod 19 will push the cable placement rack 10 to rotate around the two support plates 20, so that the cable inside the cable placement rack 10 can be flipped into the cable rack without manual pushing. The support cylinder 6 can be rotated by the rotating column 5 in the support frame 2, and the length of the support cylinder 6 can be adjusted by the threaded column 7, so as to ensure that the threaded column 7 can be installed on the wall of the cable rack.

[0036] The cable placement rack 10 is driven to rotate around the support plate 20 by the electric telescopic rod 19, realizing the automatic conversion of the cable from a horizontal lifting state to an inclined placement state. There is no need for manual pushing and pulling of the cable, avoiding the physical consumption problem of manually pushing the cable onto the rack. At the same time, it also avoids the risk of cable slippage caused by asynchronous manual operation, further improving the practicality of cable lifting.
