Anti-abrasion and anti-bending connector

Abstract

The invention discloses an anti-abrasion and anti-bending connector. The anti-abrasion and anti-bending connector comprises a connecting body; the connecting body comprises a foundation base; an upperconnecting base and a lower connecting base which are perpendicularly crossed are vertically installed on the upper side and the lower side of the foundation base; connecting rings are installed on the upper connecting base and the lower connecting base in a hinged mode respectively; the rotating axis of the connecting ring on the upper connecting base is perpendicular to the rotating axis of theconnecting ring on the lower connecting base; according to the anti-abrasion and anti-bending connector, the two connecting rings are arranged; the connecting rings can rotate relative to the connecting body; no matter in which state the connector enters a traction wheel, the connecting rings can always be attached to the surface of the traction wheel through rotation, and local tension of a traction rope cannot be increased; the connecting rings rotate relative to the connecting body to adapt to the change of the included angle of a traction rope connector, so that extra bending force is reduced, and abrasion of the connector to the end of the traction rope is effectively reduced; and the construction safety of a power transmission line is guaranteed.

Description

Technical field[0001]The invention relates to the technical field of high-voltage power transmission line construction equipment, in particular to a wear-resistant and bend-resistant connector.Background technique[0002]During the construction of the transmission line conductors, secondary unwinding traction ropes are required, and the traction ropes need to be connected by special connectors. Since the connector enters the traction wheel, it must have a certain degree of bending resistance, so it is called a bending resistance connector. In the past, bending resistant connectors were mostly designed as D-shaped, such asfigure 1 As shown in the figure, it is composed of a connecting ring 11, a pin shaft 13 and a shaft sleeve 12. When using, first remove the pin 13 and the shaft sleeve 12, put the two traction rope end sleeves into the connecting ring 11, and then install the upper pin 13 and the shaft sleeve 12, and realize the connection of multiple traction ropes through the connec...

AI Technical Summary

Problems solved by technology

[0003] 1. Connectors with bushings, bushing gaps and opening edges will cause wear on the traction rope;

[0004] 2. For connectors without bushings, due to lack of bushings, the radius of gyration of the traction rope sleeve is reduced and the traction rope is damaged;

[0005] 3. During use, after the connector enters the traction wheel, with the rotation of the traction wheel, the position of the anti-bending connector changes continuously on the wheel and between the two wheels, and the change of the angle between the joint of the traction rope makes the gap between the bushing and the opening edge will cause serious wear to the end of the rope, such as image 3 As shown in B in the middle; it cannot be close to the wheel groove, resulting in an increase in the local tension of the traction rope;

The above technical solution solves the problem of accurately identifying different bending-resistant connectors in the night sky, but does not solve the problem that the change in the angle between the joints of the traction rope will cause serious wear on the end of the traction rope due to the gap between the bushing and the edge of the opening
