Problems solved by technology

[0002] Since the wires are exposed outdoors at high altitude, they need to be overhauled frequently, and flying cars and metal ladders are needed for this kind of high-altitude line maintenance. However, the flying cars on the market currently have a single function, although the styles are different. , but they all have one characteristic: the flying car and the metal ladder are independent entities, and the flying car includes several different types, which need to be carried separately during construction; but because the power transmission and distribution lines are in the wild, it is both troublesome and difficult to carry separately. It is easy to miss, which brings inconvenience to maintenance and construction

Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] As shown in the figure, the flying car type combined ladder of this embodiment includes a single-split wire flying car composed of two sets of pulleys 1. The upper and lower ends of the pulleys 1 are provided with installation through holes, and the installation through holes at the lower end of the pulleys 1 are connected to There is a ladder 3. This structure is suitable for single-split wires. When there are four groups of pulleys 1, the four groups of pulleys 1 are connected end-to-end through the connecting pipe 2 to form a double-split wire fly. Both sides of the upper end constitute a flying car-type combined ladder for vertically arranging double-split conductors; the structure can be disassembled and assembled at will according to the needs of use, achieving the portability of line construction and maintenance.

Abstract

The invention discloses a galloping type combined ladder which comprises at least two groups of tackles and connection pipes, wherein installation through holes are formed in the upper end and the lower end of each tackle; a crawling ladder is connected to installation through holes in the lower ends of the tackles; when the tackles are divided into at least four groups; two adjacent tackles at the upper part and the lower part are connected end to end through the connection pipes; selective combination can be performed according to different use requirements, and the application range is wider; a defect that carried tools in a large number are complex due to construction of different lines is overcome; objects of lighting and multi-function of line construction tools are realized; and the galloping type combined ladder is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of maintenance tools for power transmission lines, and relates to a flying car type combined ladder. Background technique [0002] Since the wires are exposed outdoors at high altitude, they need to be overhauled frequently, and flying cars and metal ladders are needed for this kind of high-altitude line maintenance. However, the flying cars on the market currently have a single function, although the styles are different. , but they all have one characteristic: the flying car and the metal ladder are independent entities, and the flying car includes several different types, which need to be carried separately during construction; but because the power transmission and distribution lines are in the wild, it is both troublesome and difficult to carry separately. It is easy to miss, which brings inconvenience to maintenance and construction. Contents of the invention [0003] In view of this, the object of the presen...
