Description

Technical Field

[0001] This utility model relates to the field of wiring protection, and more specifically, to wiring protection tools for overhead power transmission lines. Background Technology

[0002] Spacer bars are crucial protective tools for overhead power transmission lines. They are hardware installed on the split conductors of such lines to maintain proper spacing, preventing them from whipping, colliding, or becoming too close together due to wind, icing, or other factors. This suppresses light wind vibrations and span oscillations. Spacer bars are typically installed in the middle of the span, one every 50 to 60 meters, ensuring neat conductor alignment and stable spacing. Based on performance characteristics, spacer bars can be classified as rigid, damped, and flexible. Damped spacer bars, with their built-in damping elements, effectively absorb vibration energy, protecting conductors from fatigue damage. Spacer bars play a vital role in high-voltage transmission lines, ensuring the safe and stable operation of the lines.

[0003] The installation of spacers usually needs to be carried out at high altitudes in harsh working environments. However, when installing spacer clamps on conductors, bolts, nuts and copper washers are used to fix the clamps to each conductor, and the tightness of the bolts must be ensured. If the bolts are loose or damaged, there is a risk that the spacer will detach from the conductor. Utility Model Content

[0004] The purpose of this utility model is to provide a wiring protection tool for overhead power transmission lines, so as to solve the problem that when spacers are installed in harsh environments at high altitudes, it is necessary to ensure that the bolts are tightened to prevent the clamps from separating from the conductors, and to facilitate use.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] The present invention relates to a wiring protection tool for overhead power transmission lines, comprising a frame and six dispersing rods evenly installed on the circumference of the frame. Each of the six dispersing rods has a clamping hook at one end and a locking component on the side surface of the outer end of the six dispersing rods. The clamping hook and the locking component correspond one-to-one. The clamping hook includes an outer open ring and an inner open ring disposed inside the outer open ring. The outer open ring is fixedly connected to the outermost end of the dispersing rod, and a locking groove is formed on the side surface of the open end of the outer open ring.

[0007] Preferably, one end of the dispersing rod is provided with an installation groove, and the side surface of the outer end of the dispersing rod is provided with a cylindrical groove. The installation groove and the cylindrical groove are connected, and a connecting through groove is provided on one side of the cylindrical groove.

[0008] Preferably, the locking component includes a rotating column that matches the cylindrical groove and a forked rod installed on the side surface of the rotating column. One rotating column is provided with two sets of forked rods, and one end of the forked rod is provided with a fixing bolt, which matches the connecting groove.

[0009] Preferably, the circumferential surface of the rotating column is in contact with the circumferential surface of the inner open ring.

[0010] Preferably, the distance between the two engagement slots is equal to the distance between the two connecting slots.

[0011] Preferably, the outer ring surface of the inner open ring is provided with a straight tooth surface, and the inner open ring is in contact with the circumferential surface of the rotating column through the straight tooth surface.

[0012] Preferably, the lower end of the circumferential surface of the rotating column is provided with a threaded surface, and the rotating column is connected to the outer ring surface of the inner open ring through the threaded surface.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] 1. Wiring protection tools for overhead power transmission lines utilize a unique clamping hook and locking mechanism design to achieve rapid clamping and locking of conductors. In harsh high-altitude environments, operators can quickly place the tool between the conductors and, by rotating the rotating column and utilizing the threaded engagement, quickly clamp and fix the conductors, improving installation efficiency while ensuring the stability of the connection between the spacer and the conductor, effectively preventing the risk of separation between the spacer and the conductor.

[0015] 2. Wiring protection tools for overhead power transmission lines, by adjusting the height of the rotating column and the corresponding positions of the fixing bolts and connecting slots, can control the distance between six parallel conductors, ensuring their even distribution. This not only meets the requirements of the line layout but also improves the overall aesthetics and operational safety of the line. Simultaneously, the double-layer locking mechanism further enhances the fixing effect of the spacer bars on the conductors, ensuring the stability and reliability of the conductors during long-term operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figure 1 The present invention relates to a wiring protection tool for overhead power transmission lines, comprising a frame 1 and six dispersing rods 2 evenly installed on the circumference of the frame 1. Each of the six dispersing rods 2 has a clamping hook 3 at one end and a locking member 4 on the side surface of the outer end of the six dispersing rods 2. The clamping hook 3 and the locking member 4 correspond one-to-one. The clamping hook 3 includes an outer open ring 31 and an inner open ring 32 disposed inside the outer open ring 31. The outer open ring 31 is fixedly connected to the outermost end of the dispersing rod 2, and a locking groove 33 is provided on the side surface of the open end of the outer open ring 31.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Combination Figures 2-5The dispersing rod 2 has an installation groove 21 at one end and a cylindrical groove 22 on the side surface of the outer end of the dispersing rod 2. The installation groove 21 and the cylindrical groove 22 are connected. A connecting through groove 23 is provided on one side of the cylindrical groove 22. The locking component 4 includes a rotating column 41 that matches the cylindrical groove 22 and a forked rod 42 installed on the side surface of the rotating column 41. One rotating column 41 is provided with two sets of forked rods 42. One end of the forked rod 42 is provided with a fixing bolt 43. The fixing bolt 43 matches the connecting through groove 23. The circumferential surface of the rotating column 41 is in contact with the circumferential surface of the inner open ring 32. The distance between the two engaging grooves 33 is equal to the distance between the two connecting through grooves 23. The outer ring surface of the inner open ring 32 is provided with a straight tooth surface. The inner open ring 32 is in contact with the circumferential surface of the rotating column 41 through the straight tooth surface. The lower end of the circumferential surface of the rotating column 41 is provided with a threaded surface 44. The rotating column 41 is engaged with the outer ring surface of the inner open ring 32 through the threaded surface 44.

[0027] In this embodiment, in an overhead power line, the tool is placed between six parallel conductors, and the conductors are respectively placed at the corresponding clamping hook 3 positions. The six rotating columns 41 are rotated sequentially, utilizing the meshing connection between the threaded surface 44 and the outer ring surface of the inner open ring 32. The inner open ring 32 rotates 180° inside the outer open ring 31, and the engaging groove 33 rotates to the inner side of the mounting groove 21, so that the engaging groove 33 corresponds to the connecting through groove 23. Originally, the outer open ring 31 and the inner open ring 32 were used for the opening positions where the conductors enter and exit; because the inner open ring... The rotation of 32 closes the opening and locks the wire in the clamping area of ​​the clamping hook 3. Then, the height of the rotating column 41 is adjusted so that the fixing bolt 43 corresponds to the connecting groove 23. The fixing bolt 43 passes through the connecting groove 23 and is threadedly connected to the engaging groove 33, thereby completing the fixing of the inner opening ring 32. This makes the distance between the six parallel wires equal, meeting the layout requirements of the circuit. The installation is convenient and can be completed quickly. The spacer has a double-layer locking for the wire, effectively preventing the spacer from separating from the wire.
