Hanger frame of fixed-steering pulley

Abstract

The invention provides a hanger frame of a fixed-steering pulley. The hanger frame comprises a hanger beam (8), a steering pulley and two groups of bracket assemblies (2). The bracket assemblies (2) are fixed to two sides of the lantern ring of a closed fixture (1) for replacing a single insulator respectively through connection screws (3) by two ends of a fork-shaped bracket, and then the two brackets are connected to the hanger beam (8). The steering pulley is connected to the hanger beam (8) between the two brackets. The steering pulley is formed by a pulley (6), a pulley frame (4) and a connection fork ear (5) connected to the pulley frame (4). The connection fork ear (5) is connected to the hanger beam (8) through a bolt. Adjusting holes are uniformly distributed in horizontal rows on the body of the hanger beam (8). One end of the hanger beam (8) is provided with a long groove for adjusting the connection between the hanger beam and the bracket assemblies (2) according to the different numbers and different distances of front and back insulators clamped by the closed fixture (1). The hanger frame has the advantages of convenient operation and high safety and stability.

Description

[0001] Technical Field The present invention belongs to the technical field of clamp structure for replacing insulators in the electric power industry. Background technique [0002] Replace the single-piece insulator with a closed clamp and place it on the ground and hoist the replaced insulator into the removed position for installation. Because it is difficult to install the steering block at the work place, the existing technology is to hold the removed insulator with a bottle clamp Steel caps, the operator puts the removed insulators into the ground with ropes on the insulator strings at the operation point, and then replaces them with new insulators, and the operator on the tower lifts them to the position of the removed insulators for installation. As the voltage level increases, the load on the insulators of ultra-high voltage or ultra-high voltage lines is increasing, and the weight of the insulators is getting heavier and heavier. The operator's work intensity increase...

AI Technical Summary

Problems solved by technology

As the voltage level increases, the load on the insulators of ultra-high voltage or ultra-high voltage lines is increasing, and the weight of the insulators is getting heavier and heavier. The operator's work intensity increases when lifting the insulators, and the work of replacing insulators is time-consuming and laborious. Security risks

The above problems are no longer applicable to the lifting when replacing the insulator. The insulator is replaced.
