Abstract
The utility model discloses a power transmission line ground wire lifting device, which comprises two leading screws (1) and a cross-arm fixing device (2) connected on the lower ends of the two leading screws (1). Extension plates (3) are connected on the bottoms of the leading screws (1). U-shaped rings (4) each with an opening sealed by a bolt are sleeved on adjusting holes (3.1) on the bottoms of the extension plates (3). The provided ground wire lifting device which enables rapid fixation and easy folding and unfolding operations can replace power transmission ground wire suspension clamps in a way characterized by enhanced safety, greater stability, more convenience and simpler operations.
Description
Technical field
The utility model belongs to power industry, earth wire of power transmission line line lifter apparatus structure technical field.
Background technology
Have now in changing overhead power transmission ground wire suspension clamp process, the operating type that in the past adopts had: 1. wirerope-winding method, but waste time and energy, and risk is higher; 2. Hand operating hoist working system, but operating difficulties, artificial facility loss is large, seriously influences operating efficiency, causes defective in time to get rid of, and brings great potential safety hazard to production work.
Summary of the invention
In order to solve in the overhead transmission line ground wire suspension clamp Renewal process problem of the versatility that promotes ground wire and can't realize, convenience, high efficiency, the utility model earth wire of power transmission line line lifter provides a kind of fast and easily ground wire lifting Work tool, and more changing jobs of earth wire of power transmission line suspension clamp becomes safer, more stable, more convenient, operation is simpler thereby make.
The purpose of this utility model is achieved by the following technical solution.
Earth wire of power transmission line line lifter, the utility model feature be, includes two leading screws and be connected to the cross-arm fixture of two leading screw lower ends, is connected with extension plate in the bottom of leading screw, and the adjustment hole in the extension plate bottom is socketed with the U-shaped ring that adopts bolt sealing opening.
The utility model is at the adjustment hole that vertically offers on the extension plate more than 1.
The utility model is provided with opening in ground wire line lifter cross-arm fixture central authorities.
The utility model is set to the hangers with caulking groove in the leading screw bottom; The extension plate top embeds caulking groove, adopts bolt to pass hangers, uses nut that extension plate is fixedly connected on the leading screw bottom.
The utility model folding and unfolding instrument is set to laborsaving screw mandrel, and extension plate is set to regulate the porous extension plate, and cross-arm fixture central authorities arrange opening so that the ground wire line lifter is fixed.
The beneficial effects of the utility model are, can fix fast and the line lifter of folding and unfolding easily owing to providing a kind of, thus can safer, more stable, more convenient, the more simple ground wire suspension clamp of transmitting electricity of changing of operation.
Further set forth the utility model content below in conjunction with Figure of description and embodiment.
