Abstract
The utility model discloses a jackstay for controlling direction of felled trees and bamboos in obstacle clearing process of a line. The jackstay comprises a jackstay body and a U-shaped fork; the U-shaped fork of which opening is forward is fixed at the top end of the jackstay body; an anti-skid stab of which front end is sharp is fixed at the bottom of the forward middle part of the U-shaped fork; a backward barb is fixed at the bottom of one backward side of the U-shaped fork; the jackstay body is a telescopic rod consisting of 2 to 4 supporting rods. By the adoption of the jackstay, a process that an operating personnel climbs a tree for binding is eliminated, so that an operating personnel high-altitude falling risk is avoided, the safety precaution preparation time is greatly shortened, and the passage obstacle clearing working performance of the overhead transmission line is improved; the jackstay has the advantages that working hours are reduced; the operating efficiency is high; the labor strength of operating personnel is reduced; the operation is simple, safe and reliable; the jackstay is portable.
Description
Technical field
The utility model relates to transmission line construction instrument, especially relate to a kind of control circuit remove obstacles tree bamboo swing to strut.
Background technology
Because transmission line of electricity is erected at wilderness and mountain driving mostly; circuit by way of forest farm, the special area such as Bamboo Growth district, nature reserve, economic forest zone; therefore the tree bamboo that is every year all growing a large amount of in line channel; in order to guarantee the safe operation of transmission line of electricity; must, according to < < DL/T 741-2010 overhead transmission line operating standard > >, to not meeting the tree bamboo of service requirement, must cut down.Because be, close on electrification in high voltage circuit to carry out operation, before operation, must carry out and control the security measure that tree bamboo is swung to, traditional work method is to tie up one end of stay cord by the climb up a tree top of bamboo of personnel, then by multidigit operating personnel, caught hold of the other end of stay cord, control swinging to of tree bamboo, prevent from setting bamboo and swing to circuit one side, damage circuit by pressure, another operating personnel saws the root of tree bamboo with a chainsaw, just can complete the task of removing obstacles, so not only lose time, operating efficiency is lower, and operating personnel's labour intensity is also large, poor stability.
Summary of the invention
The purpose of this utility model is to provide a kind of and saves the working time, operating efficiency is high, reduction operating personnel's labour intensity, control circuit simple to operate, safe and reliable, easy to carry are removed obstacles, and tree bamboo is swung to strut.
The purpose of this utility model is achieved in that
A kind of control circuit remove obstacles tree bamboo swing to strut, comprise rectangular tubular strut body, feature is: on the top of strut body, be fixed with opening U-shaped fork forward, in the middle bottom forward of U-shaped fork, be fixed with the anti-skidding thorn that front end is sharp-pointed, in U-shaped fork one side bottom backwards, be fixed with barb backward.
?the middle bottom backwards of U-shaped fork is a column, and column inserts in the pore on strut body top, with screw, U-shaped fork is fixed on to the top of strut body.
Rectangular tubular strut body is expansion link, 2-4 joint pole, consists of, and between the pole of adjacent two joints, by rotatable joint screw rod, is fixed or is unclamped.
In the bottom of strut body, cover has anti-skidding plastic handles.
Utility model is comprised of strut body and U-shaped fork, on the top of strut body, be fixed with opening U-shaped fork forward, in the middle bottom forward of U-shaped fork, be fixed with the anti-skidding thorn that front end is sharp-pointed, in U-shaped fork one side bottom backwards, be fixed with barb backward, and strut body is expansion link, by 2-4 joint pole, formed.During the operation of conducting transmission line cleaning screen of trees, 1. as the height of tree bamboo growth is no more than 12 meters, mobile jib is more sturdy again, can not need colligation to control the rope of swinging to, and become 30o-45o angle to control with the strut body that three poles form, concrete operation method is: operating personnel first regulates the length of strut body, hold strut body, U-shaped fork is aimed to trunk center of gravity and push hard thorn, making the tip of anti-skidding thorn thrust trunk can not slide, equally the tip of the anti-skidding thorn of another root strut body is also thrust to trunk, be then 30o-45o angle and firmly to swinging to direction, push.2. as the growing height of tree bamboo surpass 12 meters and mobile jib thick, utilize strut body to control the colligation of swinging to rope, and climb tree bamboo without operating personnel, thereby reach, stop operating personnel's falling from high altitude risk and shorten peace and arrange the effect of time, concrete operation method is: first control rope is hung in 2U type fork, utilize strut body lift the height of C.G. of tree bamboo and pass branch, then utilize 3 barbs of another root strut body to catch on to control the link of rope to be pulled down to ground, the link of control rope being put into control rope by operating personnel tightens up, when being sawed with a chainsaw the root of tree bamboo by another operating personnel, tree bamboo to be cut down is pulled to the safe region of swinging to, complete felling.3. as less in tree-walks such as mao bamboon, willow, Chinese firs, the fast seeds that grow, can directly insert trunk by the anti-skidding thorn in the middle of U-shaped fork and push, and can save in a large number peace and arrange time, increase work efficiency.
The utility model has saved the process that operating personnel climbs trees colligations, avoided the risk of operating personnel's falling from high altitude, significantly having shortened peace arranges time, improved the overhead transmission line paths operating efficiency of removing obstacles, have advantages of save the working time, operating efficiency is high, reduce operating personnel's labour intensity, simple to operate, safe and reliable, easy to carry.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of control circuit remove obstacles tree bamboo swing to strut body, comprise rectangular tubular strut body 1, on the top of strut body 1, be fixed with opening U-shaped fork 2 forward, in the middle bottom forward of U-shaped fork 2, be fixed with the anti-skidding thorn 21 that front end is sharp-pointed, in U-shaped fork 2 one sides bottom backwards, be fixed with barb 22 backward.
The middle bottom backwards of U-shaped fork 2 is a column 23, and column 23 inserts in the pore 11 on strut body 1 tops, with screw 12, U-shaped fork is fixed on to the top of strut body 1.
Rectangular tubular strut body 1 is expansion link, 2-4 joint pole 13, consists of, and between the pole 13 of adjacent two joints, by rotatable joint screw rod 14, is fixed or is unclamped.The height of whole strut body 1 can highly regulate according to the tree bamboo of need felling.
In the bottom of strut body 1, cover has anti-skidding plastic handles 15.
