Description

Reinforced spring pins for transmission lines

technical field

The utility model relates to the field of safe operation of transmission lines, in particular to a reinforced spring pin for transmission lines.

Background technique

Ordinary spring pins for transmission lines are mostly installed on the strings used to connect cross arms and wire insulators. When the tower is subjected to ups and downs in the terrain, the wires in low-lying areas of the tower are easily subjected to upward pull-out force. When the wire is pulled up , the insulator string is in a loose state, and the spring pin is easily deformed under the wind swing and upward pull force of the insulator string. A series of major equipment or power grid accidents. Therefore, the development of reinforced spring pins for transmission lines can solve the threat to transmission lines caused by the above drawbacks, thereby ensuring the safe and stable operation of transmission lines.

Contents of the invention

The purpose of the utility model is to solve the problem that the spring pin of the transmission line is easy to fail due to unreasonable structure, and to provide a reinforced spring pin for the transmission line.

The utility model is achieved through the following technical solutions:

A reinforced spring pin for a power transmission line, comprising a U-shaped steel bar, the two ends of the U-shaped steel bar are respectively connected with curved steel bars parallel to the U-shaped steel bar through connecting parts, and the curved steel bar is provided with Adapted arc-shaped notches; two curved steel bars are placed on both sides of the U-shaped steel bar, and the U-shaped steel bar and the two curved steel bars are located in the same plane; the outer sides of the two straight steel bars of the U-shaped steel bar The part is fixed with a thickened part.

Further, the thickened part is made of steel, copper or rubber material with high elasticity and high strength, and the thickness is 2mm.

The innovation of this utility model lies in the structural structure of the spring pin, one of which is the curved steel bar on both sides of the U-shaped steel bar, which is specially provided with an arc-shaped notch according to the transmission line, so that the locking effect of the spring pin is more reliable; The second is that the outer parts of the two straight steel bars of the U-shaped steel bar are fixed with thickened parts. The thickened part can play an additional role in extrusion resistance. When the thickened part is made of steel or copper, it can not only increase the strength of the spring pin Strength, and can also enhance the wear resistance of the spring pin; when the thickened part is made of rubber material, the power transmission line can be tightly clamped in the spring pin, even if the rubber is worn to a certain extent, the power transmission line can still be maintained under the elastic force of the rubber Under the action, it is tightly clamped in the spring pin. The improved spring pin avoids the disadvantages of being squeezed and deformed in the past, and can prevent the spring pin from being deformed and causing a string drop accident.

The spring pin of the utility model has a scientific design and a reasonable structure, which can prevent the spring pin from being easily subjected to upward pressure, causing the spring pin to deform, wear and lose the locking connection function, and the disadvantages of string dropping, which can prevent further expansion of defects or lead to A major safety accident, it is a reinforced spring pin for transmission lines, which has a high promotion value.
