Line clamping device for power line construction line drawing

Abstract

The invention discloses a line clamping device for power line construction line drawing, and relates to the technical field of power line construction tools. The line clamping device for power line construction line drawing comprises a jaw support, a fixed jaw and a movable jaw; the fixed jaw is located on the lower portion of the jaw support and provided with a locking jaw, the locking jaw comprises a fixing block and a transverse plate which is located at the top of the fixing block and is perpendicular to the fixing block, and the transverse plate is provided with a through hole; the fixed jaw is provided with a through groove, an eccentric shaft is arranged in the through groove, the maximum diameter of the eccentric shaft is the same as the width of the through groove, the top end of the eccentric shaft penetrates through the through hole to be exposed over the transverse plate, and the top end of the eccentric shaft is provided with a handle; the left end and the right end of the fixing block are each provided with first grooves, a first spring and a first arc-shaped clamping plate are arranged in each first groove, one ends of the first springs are fixedly connected with the fixing block, and the other ends of the first springs are fixedly connected with the first arc-shaped clamping plates. The line clamping device for power line construction line drawing has the advantages that through the locking jaw arranged on the movable jaw, the clamping force of the line clamping portion is effectively increased, and the surface damage of a clamped line cannot be caused.

Description

technical field [0001] The invention relates to the technical field of power line construction tools, in particular to a wire gripper for pulling wires in power line construction. Background technique [0002] During the construction or maintenance of power lines, it is necessary to tighten the erected power lines before fixing both ends. In order to facilitate the stretching of the power line, people have invented a wire clamp that is convenient for pulling the wire. When using it, one end of the power line is fixed on a pole, and the other end of the power line is clamped with the wire clamp. Pull the handle outward until the power line is tightened before fixing it to another pole. The existing wire clamp clamps the wires in the fixed and moving jaws, but the clamping force of the wire clamping part of the wire clamp is not enough, and the wire harness is easy to loose, thus causing safety accidents and affecting the normal power supply. In order to increase the clampin...

Problems solved by technology

The existing wire clamp clamps the wires in the fixed and moving jaws, but the clamping force of the clamping part of the wire clamp is not enough, and the wire harness is easy to loose, which will cause safety accidents and affect the normal power supply

In order to increase the clamping force of the clamping part, the surfaces of the fixed and movable jaws in the prior art are all processed with anti-slip stripes. Although the anti-slip stripes can reliably clamp the wires, it is easy to Cause surface damage to the clamped wire, and the degree of damage is difficult to control within the range stipulated by the state
