Abstract

The utility model relates to a device for power line maintenance, in particular to a soft ladder for high-voltage line maintenance. The soft ladder comprises a soft ladder and a hook installed at one end of the soft ladder, and is characterized in that a hook provided with a tightener is installed at the other end of the soft ladder. The utility model is additionally provided with the tightener on the basis of the prior soft ladder, therefore, the both ends of the soft ladder can be directly hung on a high-voltage line when the utility model is used, the soft ladder is tensioned through the tightener, and maintenance personnel directly falls to a maintenance position from a tower top, so the installation, the carrying and the use are convenient and safe.

Description

High-tension line maintenance rope ladder
Technical field
The utility model relates to power circuit maintenance device, particularly high-tension line maintenance rope ladder.
Background technology
During the high-tension line maintenance, need be up and down to high-tension line from high-pressure tower, because the tangent tower insulator all adopts composite insulator at present, particularly the extra high voltage network insulator string is longer, and iron tower is higher, and composite insulator is according to the regulation of electric power overhaul rules, do not allow climbing up and down, when the examination and repair for high-pressure circuit, can only hang rope ladder from the ground guiding line like this, the maintainer is by upwards climbing of ground, because iron tower is higher, the rope ladder swing has brought very big potential safety hazard, and labour intensity is big simultaneously; Adopt hard ladder to enter the compound inslation period of the day from 11 p.m. to 1 a.m,, install, use and transport very inconvenience because the volume and weight of hard ladder is bigger.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of installation, easy to carry is provided, high-tension line maintenance rope ladder safe in utilization.
For achieving the above object, the technical solution of the utility model is: a kind of high-tension line maintenance rope ladder, comprise rope ladder and the hook that is installed in rope ladder one end, and it is characterized in that being equipped with the hook of band tensioning apparatus at the other end of rope ladder.
Above-mentioned tensioning apparatus is the ratchet tensioning apparatus.
The utility model is on the basis of existing rope ladder, has increased tensioning apparatus, can directly the rope ladder two ends be suspended on the high-tension line so in use, by tensioning apparatus rope ladder is strained, the maintainer directly installs, carries with very easy to use to the maintenance position by cat head is following, and safety.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, during use, the upper end of rope ladder 3 is suspended on the upper conductor 1 by last hook 2, the lower draw-bar 5 on the rope ladder hangs on the lower wire 6, then by ratchet tensioning apparatus 3 with the rope ladder tension, the maintainer is by about the rope ladder.Ratchet tensioning apparatus 3 is to adopt existing ratchet strainer.
