Overhead power line power fitting manufacturing strength detection device and method

Abstract

The invention relates to an overhead power line power fitting manufacturing strength detection device and method. The device comprises a base, a fixed clamping mechanism and a tensile test mechanism; the left side of the upper end of the base is provided with the fixed clamping mechanism; and the right side of the upper end of the base is provided with the tensile test mechanism. According to the invention, a tensile test is carried out on the U-shaped hanging ring in a rapid clamping manner, so that the assembling and disassembling time of the U-shaped hanging ring is greatly reduced in the testing process of the U-shaped hanging ring, and the problem that the assembling and disassembling of the U-shaped hanging ring in the prior art still consumes a large amount of time, so that the testing efficiency of the U-shaped hanging ring is influenced is solved; and by simulating the stress state possibly occurring under the actual use condition, the strength of the U-shaped hanging ring is further tested, so that the problem that when the two sides of the U-shaped hanging ring are subjected to tensile force, the strength of the cambered surface of the U-shaped hanging ring is reduced, but the stress mode possibly existing in the implementation and use process is ignored is solved.

Description

technical field [0001] The invention relates to the technical field of electric power fittings manufacturing detection, in particular to a detection device and a detection method for the manufacturing strength of electric fittings of overhead power lines. Background technique [0002] Overhead lines mainly refer to overhead open lines, erected above the ground, and are transmission lines that use insulators to fix the transmission wires on the towers standing on the ground to transmit electric energy. The erection and maintenance are more convenient and the cost is lower, but it is easy to be affected by the weather and the environment and cause failures. At the same time, the entire transmission corridor occupies a large area of ​​land, which is easy to cause electromagnetic interference to the surrounding environment. [0003] The main components of overhead lines are: wires and lightning conductors, towers, insulators, power fittings, tower foundations, pull wires and gro...

AI Technical Summary

Problems solved by technology

[0004] 1. In the testing process of the existing U-shaped hanging rings, two U-shaped hanging rings are often connected in an arc and then stretched. Although this method simultaneously detects the two U-shaped hanging rings at the same time, it improves the The work efficiency is improved, but the disassembly and assembly between the U-shaped hanging rings still takes a lot of time, which affects the efficiency of the U-shaped hanging ring test;

[0005] 2. In the testing process of the existing U-shaped hanging rings, only attention is paid to the tensile test of the arc surface of the U-shaped hanging rings. Simultaneous stress in all directions, when the U-shaped hanging ring is stretched on both sides, its arc surface strength will be reduced, but the existing technology often only conducts tensile tests on it, ignoring the possible stress modes in the process of implementation and use
