Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insulators, in particular to a connecting hardware for assembling a suspension insulator. Background Art
[0002] Suspension insulators are important components used in high-voltage transmission lines to insulate and support conductors from towers. This type of insulator is fixed by hardware at both ends and suspended on high-voltage towers, bearing the mechanical and electrical loads of the conductors. The stable installation of suspension insulators is crucial to ensure the safe operation of the entire transmission system. Correct installation ensures that the insulator can effectively isolate the current and prevent power leakage, while also withstanding the pressure from the natural environment such as wind and snow.
[0003] In the current market, many connection fittings for suspension insulator assembly have some defects. Traditional connection fittings usually do not have an effective adjustment mechanism, which may result in the fittings not being able to accurately align the ends of the insulators during installation. They are tightened manually during installation. If they are not tightened properly, the insulator connection may not be stable enough when subjected to external forces. After long-term stress, the connection may become loose, affecting the performance of the insulator. In addition, if the installation is not in place, it will increase the difficulty and cost of subsequent maintenance and increase the risk of power system failures, such as line breaks or short circuits, which will directly threaten power supply safety.
[0004] Therefore, a connection fitting for assembling a suspension insulator is needed to solve the above technical defects. Utility Model Content

A plurality of screw holes 9 are provided in the counterweight bar 10, and the screw holes 9 are provided at equal intervals on the left and right sides of the counterweight bar 10. The fourth bolts 8 are fixed and pass through the screw holes 9. The stabilizing member 4 is in a "Z" shape, and the fastening side member 1 is in an "L" shape. A support rod 6 is obliquely supported and fixed between the inner side wall of the stabilizing member 4 and the top of the assembly part 7. A group of third bolts 5 are installed at each end of the support rod 6, and the support rod 6 is fixed on the stabilizing member 4 through the third bolts 5;
[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, first connect and assemble a group of stabilizing members 4 on the left side with the fastening side member 1, and after fixing it with the second bolt 3, insert one end of the suspension insulator into the inner wall of the fastening side member 1, use the first bolt 2 to fix the fastening side member 1 and the insulator, and then clamp another group of stabilizing members 4 on the counterweight bar 10, move it to the fastening side member 1 on which it is assembled and abut against the other end of the insulator, and then tighten the fourth bolts 8 one by one, so that the two groups of stabilizing members 4 can tightly fix the insulator from both sides and make it suspended in the air. While completing the fixation, the counterweight bar 10 at the bottom also increases the symmetry and stability of the installation. The counterweight bar 10 can be selected or removed on site as needed.
[0026] Embodiment 2: The middle position of the stabilizing member 4 is a steel plate 13, and both sides of the steel plate 13 are hollow grooves 11. Multiple groups of reinforcing ribs 12 are arranged between the hollow grooves 11 and the steel plate 13. The reinforcing ribs 12 are steel ribs.

Each group of stabilizing parts 4 can be detached from the fastening side part 1 to facilitate the replacement of new parts. When assembling, it is necessary to first install the support rod 6 on the stabilizing part 4, and then install it on the metal. When the hardware is subjected to external impact, the support rod 6 can provide a reverse supporting force from the inside to reduce deformation and impact damage. Inside the stabilizing member 4, multiple sets of reinforcing ribs 12 can strengthen the internal stress support. A heat dissipation groove 14 is welded in the middle of the steel plate 13. While playing a heat dissipation role, it also avoids the problem of the integrated steel being too thick and overloaded, reduces the suspension pressure caused by the excessive weight of the hardware itself, and reduces the suspension risk. At the same time, anti-rust rubber 16 is bonded in the bottom groove 15 at the assembly part 7 to prevent rust due to long-term exposure to the external environment. While completing the fixation, the counterweight bar 10 at the bottom also increases the symmetry and stability of the installation.
