Problems solved by technology

[0002] In the process of line transformation in rural power grid construction, corner poles and top gear poles are often encountered. When the wires slip off the insulators when the wires are tightened, it is difficult to lift the wires to the insulators by manpower, especially for large lines with large spans, the weight of the line and the insulator. The tension reaches thousands of kilograms. The general method is to lift the thread after loosening the thread, but this method wastes a lot of manpower and material resources invisibly.

Embodiment 1

[0021] Such as figure 1 As shown, this embodiment includes a support base 1, a lifting lever 6 is hinged in the middle of the support base 1, and a wire tightener 9 is provided at the end of the lifting lever 6, and a connecting plate 4 and a supporting plate 3 are also included. The middle part of the connecting plate 4 is provided with a support tube 2, one end of the support plate 3 is connected with the lifting lever 6, the other end of the support plate 3 is placed in the support tube 2 and hinged with the support tube 2 through a pin shaft, and along the axis direction of the support tube 2 An opening for the support plate 3 to freely pass is provided on the upper section of its outer wall.

[0022] The specific operation method is as follows: fix the support base 1 and the connecting plate 4 to the appropriate position on the pole or iron tower by bolts, and ensure that there is a distance between the connecting plate 4 and the supporting base 1, so as to satisfy the li...

Abstract

The invention discloses a wire lifting device of a power transmission line aerial wire. The wire lifting device comprises a supporting seat, wherein the middle of the supporting seat is hinged to a lifting lever; the tail end of the lifting lever is provided with a wire tightening device; the middle of a connecting plate is provided with a supporting cylinder; one end of the supporting cylinder is connected with the lifting lever; the other end of the supporting plate is arranged in the supporting cylinder and is hinged to the supporting cylinder through a hinge pin; the upper section of the outer wall of the supporting cylinder is provided with an opening, along an axis direction of the supporting cylinder, for the supporting plate to freely pass. The supporting seat, the lifting lever, the supporting plate, the connecting plate, the supporting cylinder and the wire tightening device are used for forming a hoisting structure, and the hoisting structure directly abandons a traditional wire lifting way, a wire sliding down from an insulator is clamped by a hook on the wire tightening device, a wrench is manually vertically swung to realize the vertical movement of the hook, i.e., the wire is driven to lift, and the wire is wound on the insulator again through artificial regulation.

Description

technical field [0001] The invention relates to the field of line distribution, in particular to a wire lifter for an overhead line of a power transmission line. Background technique [0002] In the process of line transformation in rural power grid construction, corner poles and top gear poles are often encountered. When the wires slip off the insulators when the wires are tightened, it is difficult to lift the wires to the insulators by manpower, especially for large lines with large spans, the weight of the line and the insulator. The tension reaches thousands of kilograms. The general method is to loosen the thread and then lift the thread. However, this operation method wastes a lot of manpower and material resources. Contents of the invention [0003] The purpose of the present invention is to provide a wire lifter for overhead wires of transmission lines, which facilitates rapid lifting of conductors to insulators during line reconstruction of rural power grids, and...
