Description

Technical Field

[0001] The invention belongs to the technical field of power engineering cable construction, and in particular relates to a portable power cable terminal fixing device and a use method thereof. Background Art

[0002] In the construction of power cables, the production of cable terminals is an important part of ensuring the safety and performance of the cables. This work requires the careful treatment of the insulation layer, semiconductor layer, and shielding layer of the cable to prevent any interference from impurities. However, in traditional operations, cable terminals are often made on the ground, where dust, moisture, and debris on the ground are easily adhered to the surface of each layer of the cable, thus affecting the quality of the cable terminal production and may even bring risks such as poor insulation, breakdown, or operational failure. This effect is particularly prominent in humid and dusty environments, making it difficult to ensure the quality of cable construction, which in turn affects the stability and security of the power grid.

[0003] To solve this problem, a variety of cable head brackets have been developed on the market to raise the cables off the ground and reduce interference from dust and debris. However, these brackets generally have the following problems:

[0004] 1. Large size: Many brackets are complex in design, and assembly and disassembly are troublesome, which makes them inconvenient to use in small or high-altitude work places;

[0005] 2. Inconvenient transportation: The traditional support structure is heavy and bulky, requiring special transportation tools, and is difficult to use flexibly at different construction sites, limiting its convenience;

[0006] 3. The clamping mechanism of the bracket is not firm: it is difficult for the clamping mechanism of the bracket to firmly fix the cable, and it is easy to loosen or slide during operation, affecting the manufacturing accuracy and safety of the cable head;

[0007] 4. Unstable legs: Many stands have poorly designed legs that make it difficult to maintain stability on uneven ground.

[0008] It is easy to topple or shake, which increases the difficulty of construction and safety risks.

[0009] The above problems result in poor performance of traditional brackets in field applications and low utilization rate, and fail to truly solve the pain points of cable terminal head production. These defects urgently need to be improved through more portable, stable and easy-to-operate technical solutions to meet the actual needs of cable head production brackets in power construction. Summary of the invention
