Power distribution network cross arm installation adjuster

Abstract

The invention discloses a power distribution network cross arm installation adjuster. The power distribution network cross arm installation adjuster comprises arc-shaped main body frames, an arc-shaped lug frame I and an arc-shaped lug frame II, wherein the arc-shaped main body frames are uniformly distributed into four groups in an adjacent manner; the four groups of adjacent arc-shaped main body frames are rotationally connected through pin shafts respectively; the arc-shaped lug frame I and the arc-shaped lug frame II are rotationally connected with the adjacent arc-shaped main body frames through pin shafts respectively; a convex lug plate I and a convex lug plate II which are of an integrated structure are arranged on the arc-shaped lug frame I and the arc-shaped lug frame II respectively; the convex lug plate I and the convex lug plate II are fastened and connected through two groups of bolts which are arranged in parallel; and the two ends of each bolt are in threaded fit connection with a limiting block and a fastening screw cap respectively. By adoption of the technical scheme, the power distribution network cross arm installation adjuster is simple in structure and convenient to assemble and install, and can realize operation by a single person, so that the working efficiency and safety are improved and the labor cost is lowered.

Description

technical field [0001] The invention relates to the technical field of power distribution installation, in particular to a distribution network cross-arm installation adjuster. Background technique [0002] The construction of distribution network projects is an important link in the development of electric power. With the improvement of lean management, higher requirements are put forward for construction safety, cost and progress. [0003] Traditional operation method: place the pole horizontally on the ground, simply fix the cross-arm on the top of the pole, hoist the pole and cross-arm to the design position as a whole, backfill and strengthen the foundation, after confirming safety, the construction personnel climb on the pole and gradually loosen the hoop bolts, Lower the cross arm to the design position, and at the same time rotate the cross arm to be perpendicular to the line direction. At this time, it is necessary to operate cautiously and make small adjustments m...

Problems solved by technology

At this time, it is necessary to operate cautiously and make small adjustments several times. Once the descending distance is too large, it is difficult for a single person to raise the height of the cross arm again.

[0004] In addition, during the construction process of the distribution network project, the installation and adjustment of the cross-arm takes a lot of time, especially on the tension pole and multi-circuit line tower, the weight of the cross-arm is 30-80kg, and two people are required to operate at the same time. Personnel skills are required to be higher, physical exertion is high, the safety risk of two-person climbing poles, and labor costs are doubled. Therefore, we design a cross-arm installation regulator for distribution network
