Description

Technical Field

[0001] This utility model relates to the field of load-bearing device technology, and in particular to a load-bearing device for fixing cables. Background Technology

[0002] Large-section power cables need to operate stably for a long time in complex physical environments, including dynamic displacement at bridge expansion joints, high-frequency vibration in strong wind areas, highly corrosive coastal environments, and the limited space constraints of subway tunnels.

[0003] Existing cable load-bearing devices, such as U-bolt type fixing clamps, consist of hot-dip galvanized U-bolts, arc-shaped metal pressure plates, and double-nut fastening components. The inner arc surface of the pressure plate conforms to the curved surface of the cable, and a rubber buffer pad is placed between the bolt and the pressure plate. Its working principle is to generate vertical mechanical pressure by tightening the nuts on both sides, which drives the pressure plate to press the cable against the mounting base. At the same time, the rubber pad is deformed by the pressure to expand the contact area and disperse the stress. Finally, the static load-bearing fixation of the cable is achieved by relying on frictional resistance.

[0004] Modern traditional cable fixing technology mostly uses U-bolt-type fixing clamps, but they have limitations. The installation tools are complicated and difficult, and it is time-consuming and labor-intensive. The creep effect caused by the weight of large cross-section cables causes traditional clamps to gradually loosen and become unstable. Therefore, a load-bearing device for fixing cables is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a load-bearing device for fixing cables, aiming to improve the problems of complicated tool use and unstable fixing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A load-bearing device for fixing cables includes a base, a lower shell fixedly connected to the top of the base, an upper shell mounted on the top of the lower shell, an upper rotating ring installed inside the upper shell, a lower rotating ring installed inside the lower shell, a lever fixedly connected to the outside of both the upper and lower rotating rings, a sliding groove formed inside both the upper and lower rotating rings, a fixed rod rotatably connected inside the sliding groove, grooves formed on the inner walls of both the upper and lower rotating rings, a rotating rod rotatably connected to the inner walls of both the upper and lower rotating rings, a pressure plate rotatably connected to the outside of the rotating rod rotatably, a pressure block fixedly connected to the other end of the pressure plate, a rotating rod rotatably connected to the inside of the pressure block, and a support assembly fixedly connected to one side of the base.

[0008] As a further description of the above technical solution:

[0009] The support assembly includes a support rod, a threaded post is fixedly connected to the top of the support rod, and two fixing plates are fixedly connected to one side of the support rod. The fixing plates have multiple threaded holes inside.

[0010] As a further description of the above technical solution:

[0011] Both the lower shell and the upper shell are fixedly connected to the outside of a fixing block, and the fixing block has a fixing hole inside. The lower shell and the upper shell are threadedly connected through the fixing hole.

[0012] As a further description of the above technical solution:

[0013] Both ends of the plurality of fixing rods are fixedly connected to the inner walls of the lower shell and the upper shell, and the plurality of fixing rods pass through the sliding groove;

[0014] As a further description of the above technical solution:

[0015] Each of the two ends of the plurality of rotating rods is fixedly connected to a limiting ring, and the plurality of rotating rods are located in a groove;

[0016] As a further description of the above technical solution:

[0017] The two ends of the three rotating rods are fixedly connected to the inner wall of the upper shell, and the two ends of the two rotating rods are fixedly connected to the inner wall of the lower shell.

[0018] As a further description of the above technical solution:

[0019] The outer side of the upper rotating ring is in contact with the inner wall of the upper shell, and the outer side of the lower rotating ring is in contact with the inner wall of the lower shell.

[0020] As a further description of the above technical solution:

[0021] The upper rotating ring has three pressure blocks installed inside, and the lower rotating ring has two pressure blocks installed inside. The pressure blocks are covered with rubber sleeves.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cable fixing and load-bearing device achieves synchronous upward drive of the rotating ring through a double-plate linkage design. This, in turn, causes five sets of pressure blocks to move centripetally, completing a three-dimensional cable clamp. This eliminates the complex installation and point-by-point tightening risks associated with traditional devices. The adaptive pressure block system incorporates a highly elastic liner that dynamically conforms to the cable's shape, forming a uniform surface contact and preventing sheath damage. The purely mechanical self-locking structure maintains constant pressure locking under vibration conditions, eliminating maintenance requirements. With its one-button locking, all-area protection, and inherent anti-loosening characteristics, the device significantly improves the fixing safety and reliability of large-section cables in harsh environments such as cross-sea bridges and wind farms.

[0024] 2. The modular expansion structure of this cable bearing device enables full-scene adaptability. The support rod is locked through the mounting holes inside the fixing holes, in conjunction with heavy-duty anchor bolts, so that the device can stably adapt to complex base surfaces such as inclined cable trays and curved pipe walls. Precision threaded columns are set on the top of the support rod to achieve seamless vertical stacking of multiple devices and meet the requirements of arbitrary layer height and span of cable trays.

[0033] The inner walls of the upper rotating ring 5 and the lower rotating ring 7 are both provided with grooves 16. The grooves 16 do not obstruct the rotation of the upper rotating ring 5, the lower rotating ring 7 and their components. The inner walls of the upper rotating ring 5 and the lower rotating ring 7 are rotatably connected to a rotating rod 12. The upper rotating ring 5 and the lower rotating ring 7 can rotate around the rotating rod 12. The outside of the rotating rod 12 is rotatably connected to a pressure plate 13. The pressure plate 13 can rotate around the rotating rod 12. The other end of the pressure plate 13 is fixedly connected to a pressure block 14. The rotation of the pressure plate 13 drives the pressure block 14 to rotate. The inside of the pressure block 14 is rotatably connected to a rotating rod 2 15. The pressure block 14 rotates around the rotating rod 2 15. A support assembly is fixedly connected to one side of the base 1. The support assembly can provide stable support for the entire device.

[0034] The support assembly includes a support rod 2, which provides stable support for the base 1. A threaded post 17 is fixedly connected to the top of the support rod 2, and the threaded post 17 can be threaded to the bottom of the support rod 2. The support rods 2 can be stacked one on top of the other. Two fixing plates 18 are fixedly connected to one side of the support rod 2. The fixing plates 18 can fix the entire device in different environments. Multiple threaded holes 19 are opened inside the fixing plates 18, and screws can be driven into the threaded holes 19 to fix the entire device.

[0035] Reference Figure 3Both the lower shell 3 and the upper shell 4 are fixedly connected to the outside of a fixing block 8. The fixing block 8 can fix the lower shell 3 and the upper shell 4. The fixing block 8 has a fixing hole 9 inside, and the lower shell 3 and the upper shell 4 are threadedly connected through the fixing hole 9.

[0036] Reference Figure 2 and Figure 4 Multiple fixed rods 11 are fixedly connected at both ends to the inner walls of the lower shell 3 and the upper shell 4. The multiple fixed rods 11 pass through the sliding groove 10, and the sliding groove 10 rotates around the fixed rods 11. At the same time, the fixed rods 11 can restrict the displacement of the sliding groove 10. Multiple rotating rods 12 are fixedly connected at both ends to the limiting rings 20.

Push the upper and lower levers 6 upwards at the same time. The movement of the levers 6 will drive the upper rotating ring 5 and the lower rotating ring 7 to rotate. The rotation of the upper rotating ring 5 and the lower rotating ring 7 will drive the rotation of the rotating rod 12, the pressure plate 13 and the pressure block 14. Driven by the rotation of the upper rotating ring 5 and the lower rotating ring 7, the pressure plate 13 rotates around the rotating rod 12. At the same time, under the fixation of the rotating rod 2 15, one end of the pressure block 14 will rotate around the rotating rod 2 15. While rotating, the other end of the pressure block 14 will squeeze inwards to firmly fix the cable.

[0040] The fixing plate 18 on the other side of the support rod 2 allows the entire device to adapt to different environments and be fixed in different conditions. The threaded column 17 is threaded to the bottom of the support rod 2, which can complete the stacking of the device.
