Hoisting tool for power distribution network overhead line

Abstract

The invention relates to a hoisting tool for a power distribution network overhead line. The hoisting tool for a power distribution network overhead line comprises a steel pipe I. The steel pipe I is connected to a left end of a steel pipe III. A right end of the steel pipe III is connected to a lower end of a steel pipe II. An upper end of the steel pipe II is provided with a pulley support. The pulley support is provided with a fixed pulley. The steel pipe I is hinged to one or two climbers. The steel pipe is provided with an installing hole connected with an electric pole. Compared with the prior art, the hoisting tool for a power distribution network overhead line has the characteristics that the steel pipe I is hinged to the one or two climbers, so that during use, the one or two climbers are stuck on the electric pole and the cohesion between the one or two climbers and the electric pole is tighter and tighter with increasing of a force applied to the steel pipe I; and the one or two climbers can easily form the cohesion with a tower without slipping.

Description

Technical field [0001] The invention relates to an overhead line of a power distribution network, in particular to a hoisting tool used for the overhead line. Background technique [0002] On the overhead lines of the distribution network, in order to improve the insulation, an insulated tower head needs to be installed, but the quality of the insulated tower head is relatively large, and a proprietary tool is needed to fix the insulated tower head on the pole. In the prior art, some large machines are used to install insulated tower heads, but in places such as farmland and rivers, these large machines cannot be extended, which will damage the farmland in a large area, making it difficult to install insulated tower heads in these places. The invention patent with application number "200910017747.7" introduces a "hoisting tool for overhead lines of distribution network". This device is suitable for use in farmland, rivers and other places where large machinery cannot be provided ...

Problems solved by technology

[0002] On the overhead lines of the distribution network, in order to improve the insulation, it is necessary to install an insulating tower head, but the quality of the insulating tower head is relatively large, and a special tool is required to fix the insulating tower head on the pole

In the prior art, some larger machines are used to install insulating tower heads, but in places such as farmland and rivers, these large machines cannot be stretched, and will damage farmland in large areas, making it difficult to install insulating tower heads in these places

The invention patent with the application number "200910017747.7" introduces a "hoisting tool for overhead lines of distribution network". Due to its simple structure and other advantages, this device is suitable for use in places where large machinery cannot be provided, such as farmland and rivers. But this kind of device is cumbersome to install on the pole, and if the hoop is not installed properly, it may cause the device to slip on the pole
