In the maintenance of power system overhead transmission line and upkeep operation, trees in transmission line of electricity passage may cause line tripping, even there is accident of human electric shock, cause serious consequence, therefore, often need to be to hindering the trees of power circuit security of operation to cut down, to ensure power supply and personal safety.When hindering the trees of power circuit security of operation to cut down, need control swinging to of being fallen trees, otherwise the trees of the branch that may cut down or felling contact with circuit, cause tripping operation, electric shock accidents or circuit is caused to damage.At present, carrying out traditional method that this operation adopts be: operating personnel climbs to assigned address and will be bundled in branch for controlling the rope for traction that trees swing to.This traditional work procedure is loaded down with trivial details, and not only labour intensity is large, and operating efficiency is low, and operating personnel's safety is difficult to guarantee, the security incidents such as falling from high altitude very easily occur, and has certain potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of tractive instrument of cutting down trees, it is lanyard rope that this tractive instrument of cutting down trees does not need operating personnel's climbing trees, just can control swinging to of being fallen trees, thereby effectively guaranteed operating personnel's safety, have easy to use, time and labour saving is laborsaving, the feature of increasing work efficiency.
Technical solution adopted in the utility model is: a kind of tractive instrument of cutting down trees, comprise insulating bar, by means of bindiny mechanism, be located at the jig on insulating bar top, described bindiny mechanism and insulating bar are slidably matched, described jig comprises connecting ring, the first steel loop and the second steel loop, described connecting ring middle part is connected with bindiny mechanism end, described the first steel loop and the second steel loop symmetry are articulated with connecting ring two ends, and middle part, described bindiny mechanism lower end connects pulling rope.
Best, described bindiny mechanism comprises joint sleeve and connecting rod; Described joint sleeve is provided with draw-in groove, and connecting rod is provided with the fixture block with stopper, draw-in groove and the use that is slidably matched with the fixture block of stopper.
Described bindiny mechanism comprises joint sleeve and connecting rod; Described joint sleeve and connecting rod are threaded.
Best, the interior ring of described the first steel loop and the second steel loop is distributed with irregular sawtooth.
Best, middle part, described bindiny mechanism lower end is provided with lacing hole, and lacing hole is connected with pulling rope by hook.
The beneficial effect that adopts technique scheme to produce is: the utility model is that insulating bar is connected with jig by bindiny mechanism, then jig is delivered to trees assigned address, pull the pull rope being fixedly connected with bindiny mechanism, make the first steel loop and second steel loop of jig hold trunk tightly under the effect of pulling force, thereby make to be fallen trees or swinging to of branch is effectively controlled.It is lanyard rope that the utility model can be avoided operating personnel's climbing trees, thereby has greatly improved operating personnel's personal safety, has eliminated potential safety hazard., compare with traditional operational method meanwhile, can greatly alleviate operating personnel's labour intensity, increase work efficiency, time and labour saving is laborsaving.The utility model is simple in structure, flexible and convenient to use, has promotional value widely.
