Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a shock-absorbing bracket for ground cables for signal transmission. Background Art
[0002] Cables generally consist of one or more mutually insulated conductive wires enclosed in a sealed sheath, which may be covered with a protective covering. They are laid underground, in the air, or on the seabed of rivers and lakes. Common military applications include deck cables, control cables, and field communication cables. Modern ships use a wide variety of cables, categorized by purpose, such as power cables, communication cables, and control cables. These cables consist of single or multiple strands of conductors and insulation, and are used to connect circuits and electrical appliances. Because the cables are laid with a reserved portion, the movement of the cable support caused by the ship's hull can cause significant vibrations in the cable, potentially causing wear on the sheath where it contacts the cable support, and even on the copper wires within the cable. How to improve the load-bearing capacity of ship cable connectors, construction flexibility, and overall aesthetics within a limited space is a development trend in modern shipbuilding. Existing cable transmission shock absorbers use a slender rod connection structure with low overall strength; and the existing pin anti-torsion structure has weak torsional resistance. The existing technology uses compression springs for shock absorption, which has limited shock absorption effect. Utility Model Content

[0021] like Figures 1 to 3 As shown, a signal transmission ground cable shock-absorbing bracket includes a binding plate 1, two shock-absorbing mechanisms and welding feet 6; the two shock-absorbing mechanisms are respectively located at the two ends of the bottom of the binding plate 1; the shock-absorbing mechanism includes two cross shafts 3, two sets of square rubbers 4, two connecting arms 5 and a left outer frame 2 and a right outer frame 7 with square through grooves on the two sides; the cross shaft 3 is placed in the square through groove; the square rubber 4 includes 4 rubber units and is respectively placed in the square space between the inner wall of the square through groove and the four corners of the cross shaft 3 in an interference fit manner; the two ends of the connecting arm 5 are respectively fixedly connected to the two ends of the cross shaft 3; the welding feet 6 are placed between the two shock-absorbing mechanisms, and the two ends thereof are respectively fixedly connected to the inner connecting plates of the two shock-absorbing mechanisms; the outer connecting plates of the two shock-absorbing mechanisms are respectively fixedly connected to the bottom of the binding plate 1. The welding feet 6 are in a vertical state. See Figure 1As shown, the outer connecting plate of the left outer frame 2 in the left vibration damping mechanism is fixedly connected to the bottom of the tie plate 1. The outer connecting plate of the right outer frame 7 in the left vibration damping mechanism is fixedly connected to one end of a weld leg 6. The other end of the weld leg 6 is fixedly connected to the outer connecting plate of the left outer frame in the right vibration damping mechanism (not shown). The outer connecting plate of the right outer frame in the right vibration damping mechanism (not shown) is fixedly connected to the bottom of the tie plate 1. The tie plate 1 of this utility model has cable tie grooves at both ends. The tie plate 1 of this utility model is fixedly connected to the outer connecting plates of the two vibration damping mechanisms using countersunk screws. A gap is left between the connecting arm 5 of this utility model and the left and right outer frames 2 and 7. A gap is left between the tie plate 1 and the left and right outer frames 2 and 7. The connecting arm 5 of this utility model is a stamped structure with buckle covers at both ends; the buckle covers correspond to the ends of the cross shaft 3. The connecting arm 5 is fixedly connected to the ends of the cross shaft 3 using screws through the through holes in the buckle covers. The axial planes of the cross shaft 3 align with the axial planes of the square rubber 4. A stamped rib is provided in the central region of the connecting arm 5. The two vibration damping mechanisms of the present invention have the same structure. Depending on actual design requirements, multiple groups of vibration damping mechanisms can be arranged on the binding plate 1. The two vibration damping mechanisms in each group are fixedly connected by a weld foot 6.
[0022] In the specific design, the utility model lays the cable along the length of its binding plate 1, and firmly binds the cable to the binding plate 1. A plurality of shock-absorbing mechanisms are arranged in series along the axial direction of the cable through the welding feet 6 to achieve a vibration reduction effect. Cable binding grooves are provided at both ends of the binding plate 1, and the upper part is connected to the left outer frame 2 with countersunk screws to prevent it from interfering with the cable. The square rubber 4 and the cross shaft 3 are respectively assembled into the square through grooves of the left outer frame 2 and the right outer frame 7, and the left outer frame 2 is connected to the binding plate 1 by bolts. It is tightened and connected to the other right outer frame 7 through the connecting arms 5 on both sides, and one side of the right outer frame 7 is connected to the welding feet 6, and the welding feet 6 are welded to the bottom plane. When the binding plate 1 of the utility model is subjected to vertical pressure or tension, the square rubber 4 is squeezed, and the connecting arm 5 moves in its plane, thereby providing stiffness and damping to achieve a vibration reduction effect. The stiffness of the vibration reduction mechanism of the utility model can be adjusted by changing the length of the connecting arm, and the operation is convenient. The square rubber of the utility model adopts a square cross-section and contacts the cross-axis plane. This structure has a large initial deformation stiffness and a small zero-point drift. The signal transmission cable shock-absorbing bracket of the utility model takes up a small space. Because its installation environment has very strict space requirements, the signal transmission cable shock-absorbing bracket achieves the vibration reduction requirements in a small space. There is a gap between the connecting arm 5 of the utility model and the left outer frame 2 and the right outer frame 7, so the device can also provide vibration reduction in the left and right swing directions of the cable and has good stability. There is a certain gap between the binding plate 1 of the utility model and the left outer frame 2 and the right outer frame 7. When the cable is subjected to a large load, the binding plate 1 contacts the left outer frame 2 and the right outer frame 7 to prevent the binding plate 1 from continuing to move, thereby preventing the square rubber 4 from being damaged due to excessive compression deformation. The structural design of the right outer frame 7 makes the welding foot 6 simple in structure, convenient for processing, and convenient for on-site installers to operate.
