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
The present invention relates to ladder field, specifically a kind of circuit trees cut down special arm ladder.
Background technology
Power circuit superelevation trees sweep top felling, utilize lopping chain saw or other tree felling tools to carry out after needing staff to ascend a height.Traditional work adopts single ladder by tree, and operating personnel climbs to ladder top or pushed up to climb to get into by ladder again and gets at work place, then fastens seat belts, utilizes and carry rope, sling by tree felling tool and cut down.Due to tree felling tool or length or short, branch around the long tree crown swept, and tree crown central area cannot be swept, short just has said nothing of, and meets little seeds all right, as tall and big tall and straight seeds, can be described as and has ridiculously overrated oneself! Felling like this not only brings overload operational difficulty to staff, and importantly there is many hidden dangers, the easy landing of such as staff, and operation tool weightlessness is fallen, trees Lack of support etc.
Summary of the invention
The present invention cuts down to solve current power circuit superelevation trees the difficult problem run into, and provides a kind of circuit trees and cuts down special arm ladder.
The present invention is achieved by the following technical solutions: circuit trees cut down special arm ladder, comprise the base with tripod, the rotating disk of rotational support on base, be fixedly supported to the square ladder on rotating disk and small-sized strand grinding machine, the reverse wheel of the terraced top middle portion in the side of being installed on, the fixed pulley on terraced top, the side of stretching out
Pull rope on small-sized strand grinding machine is connected on Fang Dou by reverse wheel, fixed pulley traction successively, described square ladder is made up of some ladder section, each ladder section comprises four cleat stanchions and four cross bars, cross bar is individually fixed in and surrounds one square between cleat stanchion between two, expansion fit between adjacent ladder section; Every root cleat stanchion of side's terraced middle and upper part ladder section is connected with bracing wire, and the other end of bracing wire is fixed on ground by anchor pole.
During concrete use, below of falling trees needed for tripod is installed on by demand, bracing wire is fixed on bottom surface by anchor pole, and operating personnel's carrying implement enters in Fang Dou, makes Fang Dou to desired height by small-sized strand grinding machine pulling traction rope; Or first make Fang Dou to desired height by small-sized strand grinding machine pulling traction rope, operating personnel climbs in Fang Dou by square ladder again, can carry out the work.
Circuit trees of the present invention cut down special arm ladder, have effectively stopped the generation that people is liability accident, have alleviated the labour intensity of operating personnel, safe and convenient, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation that circuit trees of the present invention cut down special arm ladder.
The assembling schematic diagram of Fig. 2 side of being ladder and Fang Dou.
In figure: 1-tripod, 2-base, 3-rotating disk, the small-sized strand grinding machine of 4-, 5-reverse wheel, 6-fixed pulley, 7-pull rope, 8-cleat stanchion, 9-cross bar, 10-bracing wire, 11-anchor pole, 12-guide rail, 13-side struggles against.
Detailed description of the invention
Circuit trees cut down special arm ladder, comprise the base 2 with tripod 1, the rotating disk 3 of rotational support on base 2, are fixedly supported to the square ladder on rotating disk 3 and small-sized strand grinding machine 4, the reverse wheel 5 of the terraced top middle portion in the side of being installed on, the fixed pulley 6 on terraced top, the side of stretching out,
Pull rope 7 on small-sized strand grinding machine 4 draws on the side's of being connected to bucket 13 by reverse wheel 5, fixed pulley 6 successively, described square ladder is made up of some ladder section, each ladder section comprises four cleat stanchions 8 and four cross bars 9, cross bar 9 is individually fixed in and surrounds one square between cleat stanchion 8 between two, expansion fit between adjacent ladder section; Every root cleat stanchion 8 of side's terraced middle and upper part ladder section is connected with bracing wire 10, and the other end of bracing wire 10 is fixed on ground by anchor pole 11.
See Fig. 2, when specifically implementing, a wherein cross bar 9 of each ladder section is provided with guide rail 12 all from top to bottom, the guide rail 12 of adjacent ladder section coordinates in socket, and bucket 13 sides, side have the chute be slidably matched with guide rail 12 from top to bottom.Avoid staff in side's bucket 13 during operation, side's bucket 13 swings in the horizontal direction.
