Line tree felling special bucket arm ladder

Abstract

The invention relates to the field of ladders, and in particular to aspecial bucket-boom ladder for power line tree cutting. The special bucket-boom ladder comprises a base, a rotating disc, a square ladder, a small-size twisting machine, a steering wheel and a fixed pulley, wherein the base is provided with a tripod; the rotating disc is rotationally supported on the base; the square ladder and the small-size twisting machine are fixedly supported on the rotating disc; the steering wheel is mounted in the middle of the top end of the square ladler; the fixed pulley extendsout ofthe top end of the square ladder; a traction rope on the small-size twisting machine sequentially passes through the steering wheel and the fixed pulley and is connected with a square bucket in a traction manner; the square ladder consists of a plurality of ladder sections; each ladder section comprises four ladder columns and four transverse rods; the transverse rods are respectively fixed between every two ladder columns and form a square; every two adjacent ladder sections are in telescopic matching; each ladder column of the upper middle ladder section of the square ladder is connected with a pull line; the other ends of the pull lines are fixed on the ground through anchor rods. Due to the adoption of the special bucket-boom ladder for power line tree cutting, artificial accidents can be effectively prevented, the working intensity of operators can be alleviated, the operation is safe, convenient and rapid, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of ladders, in particular to a bucket-arm ladder specially used for tree felling along the route. Background technique [0002] Sweeping and felling super-high trees on power lines requires staff to use chain saws or other felling tools after ascending. The traditional operation is to use a single ladder to lean against the tree. The operator climbs to the top of the ladder or climbs from the top of the ladder to reach the working place, then fastens the safety belt, and uses the carrying rope to lift the felling tool before felling. Because the cutting tools are long or short, the long ones can sweep the branches around the canopy, but not the center of the canopy, let alone the short ones. It’s okay to meet small tree species, but it can be said to be a gnat in the case of tall and straight tree species. Shake the tree! Such felling not only brings difficulties to the workers in overloaded work, but more important...

Because the cutting tools are long or short, the long ones can sweep the branches around the canopy, but not the center of the canopy, let alone the short ones. It’s okay to meet small tree species, but it can be said to be a gnat in the case of tall and tall tree species. Shake the tree! Such felling not only brings difficulties to the workers when they are overloaded, but more importantly, there are many unsafe hazards, such as easy slipping of workers, loss of weight and falling of operating tools, and insufficient bearing capacity of trees, etc.
