A type of locking power pole base structure

By using a locking-type power pole base structure, the movement of the insertion rod within the positioning sleeve drives the synchronous movement of the locking plate and the elastic locking components, thus solving the problems of low installation efficiency and reliability of power pole base connection structures and achieving a stable connection of power poles.

AI Technical Summary

Technical Problem

The existing power pole base connection structure has low installation efficiency, connection reliability depends on human factors, and cannot avoid axial loosening and radial sway of bolts, which affects the wind resistance, overturning resistance and seismic resistance of the power grid.

Method used

The power pole base adopts a set-locking structure. The positioning sleeve is driven to rotate by the up and down movement of the insertion rod in the positioning sleeve, which drives the arc-shaped locking plate to move synchronously. Combined with the elastic locking component, the radial and axial locking of the power pole connecting plate is achieved.

Benefits of technology

It improves the installation efficiency and stability of power pole connections, avoids axial loosening and radial swaying of bolts, and enhances the connection reliability and wind resistance, overturning resistance and seismic performance of power poles.

Abstract

This utility model relates to the technical field of power pole bases, specifically a set-locking power pole base structure, including a base fixed on a base frame, a fixing ring on the base, a drive ring rotatably mounted on the base, a positioning sleeve on the drive ring, a power pole connecting plate for fixing the power pole above the positioning sleeve, and a plug rod that is movably inserted into the positioning sleeve at the bottom of the power pole connecting plate. The plug rod and the positioning sleeve are engaged by a first linkage structure. When the plug rod moves up and down inside the positioning sleeve, it can drive the positioning sleeve to rotate clockwise and counterclockwise. Multiple arc-shaped locking plates are provided around the fixing ring. This utility model can radially lock and axially lock the power pole connecting plate fixed to the power pole, making the power pole connecting plate for fixing the power pole more stable after installation, avoiding the axial loosening defects of flange bolt fixing and the low installation efficiency of multi-bolt fixing.
