Description

Technical Field

[0001] The utility model belongs to the technical field of military cable laying, and in particular relates to a shock absorbing device for a double-end ground cable used for military 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

[0022] like Figures 1 to 3 As shown, a military signal transmission double-end ground cable shock absorption device includes a binding plate 1, two vibration reduction mechanisms and two welding feet 7; the two vibration reduction mechanisms are respectively located at the two ends of the binding plate 1 and are arranged symmetrically in opposite directions, and the upper inner connecting plates of the two vibration reduction mechanisms are respectively fixedly connected to the bottom of the binding plate 1; see Figure 1 As shown, the connecting plate on the right side of the right outer frame 4 is fixedly connected to the bottom of the binding plate 1. Two welding feet 7 are fixedly connected to the outer connecting plates of the two vibration damping mechanisms respectively; cable binding grooves are opened at both ends and the middle area of ​​the binding plate 1;

[0023] The vibration damping mechanism comprises two cross shafts 5, two sets of square rubbers 6, two connecting arms 2, and a left outer frame 3 and a right outer frame 4, each with a square through-slot on its side. The cross shafts 5 are placed in the square through-slots. The square rubbers 6 comprise four rubber units and are placed in the square space between the inner wall of the square through-slot and the four corners of the cross shafts 5 in an interference fit. The ends of the connecting arms 2 are fixedly connected to the ends of the cross shafts 5. Figure 1 As shown, the two vibration damping mechanisms are respectively located at the two ends of the tying plate 1 and are arranged in reverse symmetry, and the two welding feet 7 are respectively fixedly connected to the outer side of each vibration damping mechanism. The outer frame connecting plates located on the inner sides of the two vibration damping mechanisms are respectively fixedly connected to the bottom of the tying plate 1.

[0024] The binding plate 1 described in the present invention is fixedly connected to the right outer frame 4 connecting plate of the left vibration damping mechanism by countersunk screws. Similarly, the left outer frame connecting plate of the right vibration damping mechanism is fixedly connected to the binding plate 1 by countersunk screws. A gap is left between the connecting arm 2 described in the present invention and the left outer frame 3 and the right outer frame 4. A gap is left between the binding plate 1 described in the present invention and the left outer frame 3 and the right outer frame 4. The connecting arm 2 described in the present invention adopts a stamping structure, and buckle covers are respectively provided at both ends; the buckle covers respectively correspond to the ends of the cross shaft 5. The connecting arm 2 described in the present invention is fixedly connected to the ends of the cross shaft 5 by screws through the through holes on the buckle covers. The various axial planes of the cross shaft 5 described in the utility model are in contact with the various axial planes of the square rubber 6. The utility model is provided with stamping ribs in the middle area of ​​the connecting arm 2.

[0025] During 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. Multiple such devices are arranged along the cable axis to achieve a vibration reduction effect. The utility model's binding plate 1 has cable binding grooves at both ends and in the middle. The upper part is connected to the right outer frame 4 connecting plate of the left vibration reduction mechanism by countersunk screws. Similarly, the outer frame connecting plate on the inner side of the right vibration reduction mechanism is fixedly connected to the binding plate 1 by countersunk screws. Prevent it from interfering with the cable. The square rubber 6 and the cross shaft 5 are assembled into the through grooves of the left outer frame 3 and the right outer frame 4. The right outer frame 4 connecting plate of the left vibration reduction mechanism is connected to the binding plate 1 by bolts. It is tightened and connected to the left outer frame 3 and the right outer frame 4 through the connecting arms 2 on both sides. The left outer frame 3 connecting plate is connected to the welding foot 7, and the welding foot 7 is welded to the bottom plane. For the vibration reduction mechanism located on the right side of the binding plate 1, its specific installation method is exactly the same as that on the left side. When the binding plate 1 is subjected to vertical pressure or tension, the square rubber 6 is squeezed and the connecting arm 2 moves in a plane within its plane, thereby providing stiffness and damping to achieve a vibration reduction effect. The stiffness of the vibration reduction mechanism can be adjusted by changing the length of the connecting arm, which is easy to operate. The square rubber 6 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 vibration reduction device occupies a small space. Because its installation environment has very strict space requirements, this military signal transmission double-end cable shock absorption device achieves the vibration reduction requirements in a small space. There is a gap between the connecting arm 4 and the left outer frame 3 and the outer frame 4, so this 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 and the left outer frame 3 and the right outer frame 4. When the cable is subjected to a large load, the binding plate 1 contacts the left outer frame 3, preventing the binding plate 1 from continuing to move and preventing the square rubber 6 from being damaged due to excessive pressure deformation. The structural design of the left outer frame 3 makes the welding foot 7 simple in structure, easy to process, and convenient for on-site installers to operate.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
