Description

Technical Field

[0001] The utility model relates to the technical field of cable erection, in particular to an overhead cable support mechanism with a steel core and a high-conductivity aluminum stranded wire core. Background Technique

[0002] An overhead cable (fully called an overhead insulated cable) is an overhead conductor equipped with an insulating layer and a protective outer skin. It is a special cable manufactured using a production process similar to that of a cross-linked cable and is a new power transmission method between overhead conductors and underground cables. Overhead cables are all single-core and can be divided into hard aluminum wire structures, hard-drawn copper wire structures, aluminum alloy wire structures, steel core or aluminum alloy core support structures, and self-supporting three-core stranded structures (the wire core can be hard aluminum or hard copper) according to their different structures. Since overhead cables are used at high altitudes and are subject to greater external forces, support structures are used to fix and support the cables. Existing overhead cable support structures are difficult to flexibly fasten to overhead cables of different sizes, with limited applicability and inconvenience in use. Secondly, they do not have a buffer mechanism, resulting in greater external force impact on overhead cables at high altitudes, thereby affecting the service life of the cables.

[0003] To solve the above problems, this case was born. Content of the Utility Model

[0023] Referring to the attached Figure 3 shown, the limiting member 8 includes a support seat two 12, a limiting wheel two 11 is arranged on the support seat. Both sides of the support seat two 12 are provided with support rods 14, and a pressure seat 15 is sleeved on the upper side of the support rods 14. Buffer springs 16 are respectively arranged on both sides between the pressure seat 15 and the support seat two 12. A limiting wheel three 17 is arranged on the lower side of the pressure seat 15. The limiting wheel two 11 is opposite to the limiting wheel three 17 up and down. The buffer spring 16 is sleeved on the support rod 14, so that the distance between the limiting wheel three 17 and the limiting wheel two 11 can be adjusted after the pressure seat 15 is pressed, so as to stably fasten the overhead cable and be able to flexibly loosen the pressure for replacement.
