Problems solved by technology

[0003] At present, during the deployment of power transmission and distribution lines, due to the long tensile section, it is necessary to straighten in time when dead bends and slow bends occur. The existing wire straightening tools mainly rely on wrenches and pliers, or with the help of Pulling straight, not only the work efficiency is low, but also prone to loose strands, which poses a certain safety hazard

Embodiment Construction

[0008] The embodiment is described in detail with reference to the accompanying drawings. In the present invention, a screw 5 is screwed up and down through the center of a lifting support plate 3. A handle 1 is symmetrically installed on both sides of the top of the screw, and a pressure is fixed at the lower end of the screw. Line plate 6, line pressing grooves are provided on the bottom surface of the line pressing plate, a symmetrical movable support plate 4 is installed on both sides of the lifting support plate to rotate with pins 2 respectively, and the lower ends of each movable support plate are respectively fixed downward A symmetrical U-shaped screw 7 is equipped with a movable wire clamping plate 8 on each U-shaped screw, and a nut 9 is screwed to the U-shaped screw under each movable wire clamping plate. When the wire is straightened, clamp the two ends of the dead-bend part of the wire into the two U-shaped screws, and then use the handle to rotate the screw and us...

Abstract

Disclosed in the invention is a lead alignment tool. A penetrating screw rod is in screw joint with the center of a lifting support plate; a handle is installed at the top of the screw rod in a two-side symmetrical mode; and a wire pressing plate is fixed at the lower end of the screw rod. A pair of symmetrical movable support plates are rotatedly installed at the two sides of the lifting support plate respectively by pin rolls; symmetrical U-shaped screw rods are fixed downwardly and respectively at the lower ends of the movable support plates; movable wire clamp plates are respectively installed at the U-shaped screw rods; and nuts are respectively connected to the U-shaped screw rods under the movable wire clamp plates by a screwed way. According to the invention, two ends of a bent lead can be clamped by the two U-shaped screw rods and the lead is supported and straightened by the wire pressing plate, thereby effectively avoiding a string scattering phenomenon and ensuring the construction quality; and the work efficiency is high.

Description

[0001] Technical field: [0002] The invention is a guiding straightening tool used for straightening dead bends and slow bends in the process of wire spreading and laying of power transmission and distribution lines. Background technique: [0003] At present, during the deployment of power transmission and distribution lines, due to the excessively long tensile section, straightening needs to be carried out in time when dead and slow bends occur. The existing wire straightening tools mainly rely on wrenches and pliers, or with the help of The pulling force is straightened, not only the work efficiency is low, but also the phenomenon of loose stock is prone to certain safety risks. Summary of the invention: [0004] The purpose of the present invention is to provide a wire straightening tool which can straighten the spread wire in time, has high working efficiency and guarantees the construction quality. [0005] The technical scheme of the present invention is completed in the ...
