The installation connecting piece is welded on the long side of the triangular double-layer framework. The end portion installing hole is arranged on the other acute angle position of the triangular double-layer framework. The top installing hole is arranged on the obtuse angle position of the triangular double-layer framework. A rope tied with a suspension hook is wound on the intermediate pulley and the end portion pulley. The overhead ground wire lifting device in a power transmission line has advantages of a simple principle structure, light weight, high intensity, easy production and construction, reduced manpower consumption, and high work efficiency.

Description

An overhead ground wire lifting device for transmission lines

technical field

The utility model relates to a wiring tool for power equipment, in particular to a lifting device for an overhead ground wire of a power transmission line.

Background technique

At present, old-fashioned wooden poles are mostly used to transfer overhead ground wire loads on transmission line poles and towers. Due to the poor corrosion resistance of the wooden pole and the lifting load it can bear is also difficult to calculate, the weight of the wooden pole is about 15 kg. Because most of the pole towers are located in high mountains, the labor intensity of the operators is increased during the work process. These reasons Cause and big hidden danger to safe production.

Utility model content

The purpose of the utility model is to ensure the strength and reduce the weight at the same time, and especially provides a lifting device for the overhead ground wire of the transmission line.

The utility model provides a lifting device for overhead ground wires of transmission lines, which is characterized in that: the lifting device for overhead ground wires of transmission lines includes a triangular double-layer frame 1, a middle pulley 2, an end pulley 3, and a connecting piece 4 , 5 mounting holes at the end, 6 mounting holes at the top;

Wherein: the overall shape of the triangular double-layer frame 1 is an obtuse-angled isosceles triangle structure, the middle pulley 2 is installed in the middle of the long side through the shaft, and the end pulley 3 is installed at an acute angle of the triangular double-layer frame 1 through the shaft;

The installation connector 4 is welded on the long side of the triangular double-layer frame 1, the end mounting hole 5 is located at another acute angle of the triangular double-layer frame 1, and the top mounting hole 6 is located at an obtuse angle of the triangular double-layer frame 1; The cable of the hook is wound on the middle pulley 2 and the end pulley 3 .

The installation connector 4 is a structure of two connecting pieces with installation holes.

Use the end mounting holes 5 and the top mounting holes 6 to install the entire transmission line overhead ground wire lifting device on the bracket through bolts, and lift the cables through the hooks on the cables.

Advantage of the utility model:

The overhead ground wire lifting device for transmission lines described in the utility model has the advantages of simple principle and structure, light weight and high strength, which is convenient for manufacture and construction, reduces manpower consumption, and has high work efficiency.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Figure 1 is a schematic diagram of the principle structure of the lifting device for the overhead ground wire of the transmission line.
