Description

All-dimensional fixed combined ladder device for pruning trees of power transmission line and using method

Technical Field

The invention provides an all-dimensional fixed joint ladder device for tree pruning of a power transmission line and a using method thereof, and belongs to the field of national power grid safety facilities.

Background

With the rapid development of society, the conditions of road greening and large-area nursery garden planting are gradually increased, the contradiction of tree lines in a line protection area is increasingly prominent, and the safety operation of a power transmission line is seriously threatened. At present, tree trimming work in a line protection area mainly comprises two modes of climbing trees and trimming by adopting common ladders such as a herringbone ladder and a single-face ladder.

The method for pruning trees by climbing trees is an unconventional mode for eliminating hidden dangers in emergency situations, generally, the method is carried out under the conditions that the situations are critical and climbing tools are lacked around the personnel, the personnel are required to have the tree climbing capacity and the surrounding environment has climbing conditions, and the mode for pruning trees is not advocated due to the fact that great safety risks exist when trees are climbed.

At present, the main tree pruning mode is the herringbone ladder and the single-side ladder pruning mode, but still has a plurality of problems. Firstly, the height of a common aluminum alloy single ladder is fixed, the common aluminum alloy single ladder cannot be erected to the required trimming height, an operator needs to climb trees if necessary, and the operator can encounter dry branches, thin branches and broken branches in the tree climbing process, so that the falling risk exists; secondly, the common aluminum alloy single ladder needs to be supported by personnel to prevent the ladder body from sliding and collapsing in the using process, and more personnel are needed; thirdly, the herringbone ladder and the single-side ladder are easy to fall from high places due to no safety belt protection in the climbing process; fourthly, the common aluminum alloy single ladder has fixed length, heavier weight, is not easy to carry and has use limitation.

Therefore, there is a need to develop a tree pruning tool that is safe, efficient, and easy to use on-site.
