Description
Technical field
The present invention relates to the hoisting tool on a kind of overhead transmission line, especially a kind of 500kV overhead transmission line tangent tower lightning conducter lifting operation device.
Background technology
At present, we,, when processing the pungent merely I II line of 500kV ground line defect, need change optical cable and protect lines work.In operation, personnel find, because of the pungent I II transmission tower type reason of chatting, lightning conducter cross-arm length is protected lines length much smaller than optical cable, when this just causes changing optical cable and protects lines, without suitable instrument, can use.And ace is narrow due to ground wire, can only hold a people and carry out operation, cause work to complete abnormal difficult.Personnel can only take to make property-line line lifter to lift by crane a side under ground wire cross-arm, and then personnel carry out the mode of operation at the opposite side of ground wire hanging point.The drawback of this method is because hitch point is nearer, operating personnel is stressed relatively large in protecting the dismounting of lines and installation process, and in operation, need again at ground wire hanging point opposite side, to carry out secondary hoisting, cause the activity duration to lengthen, thereby increased operating risk.
Analyze the contradiction occurring in operation, operating personnel is when the operation of lightning conducter cross-arm place, and due to lightning conducter cross-arm design reasons, its width is less than the length that lightning conducter protects lines, and while causing operation like this, the Heave Here of line lifter can only be positioned at and protect on lines.Therefore operation is very inconvenient, wastes time and energy.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind of simple in structure, easy to use, 500kV overhead transmission line tangent tower lightning conducter lifting operation device that cost is low, time saving and energy saving.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of 500kV overhead transmission line tangent tower lightning conducter lifting operation device, and its key technology is: it comprises crossbeam, what be arranged at crossbeam two ends is U-shaped hook for catching on the line lifter of lightning conducter and being located at two of crossbeam middle part for the bottom being connected with lightning conducter cross-arm;
Described line lifter comprises stay bolt and the suspension hook connecting with stay bolt bottom;
Described crossbeam medium position arranges two elongated slots that keep at a certain distance away, and described hook top is through this elongated slot, and the top of described hook is provided with external screw thread (forming logical buckle structure), is provided with supporting nut above it.
Described crossbeam adopts channel-section steel or angle steel, and its length is 1.5～2.5m, and described line lifter is 50 ㎜ apart from crossbeam edge, and described elongated slot is offered along crossbeam length direction, and length is 10 ㎝.
The beneficial effect that adopts technique scheme to produce is:
The present invention is provided with a crossbeam, is provided with line lifter and hook on crossbeam, simple in structure, and easy to make, after employing, can increase work efficiency, and reduces labour intensity, guarantees work safety, quick.The present invention is applicable to 500kV overhead transmission line tangent tower and lightning conducter is lifted by crane on ground wire cross-arm for operating personnel, thereby carry out easily, to protecting lines, removes and installment work.

Wherein, 1, crossbeam, 2, nut, 3, hook, 5, stay bolt, 6, suspension hook, 7, elongated slot.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed.
Referring to accompanying drawing 1-3, the present embodiment comprises crossbeam 1, what be arranged at crossbeam 1 two ends is U-shaped hook 3 (integral body is J type) for catching on the line lifter of lightning conducter and being located at two of crossbeam 1 middle part for the bottom being connected with lightning conducter cross-arm;
Described line lifter comprises stay bolt 5 and the suspension hook 6 being connected with stay bolt 5 bottoms;
Described crossbeam 1 medium position arranges two elongated slots that keep at a certain distance away 7, and described hook 3 tops are through this elongated slot 7, and the top of described hook 3 is provided with nut 2.
The present invention is by changing the position of Heave Here in operation, with the crossbeam 1 that a high-strength corner iron (or channel-section steel) is made, it is main material, at its punching two ends, install ground wire line lifter additional, crossbeam 1 both sides, center are equipped with adjustable hook 3, thus solved cannot near operation hanging wire dot center problem.
The lightning conducter model inquiry at present conventional according to 500kV draws, its weight at 450 (kg/km) between 600 (kg/km), and the vertical span of Southern Hebei Network 500kV circuit is between 400m to 800m, we choose the maximum that may occur, i.e. 600*0.8=480kg.The maximum, force that ground wire hardware tool bears is less than 500kg, and we choose common thin-wall channel and just can meet the demands.
Therefore, choose 1.5 to 2.5m elongated slot steel, two line lifters are installed far from 50mm place, edge in its positive both sides, in both sides, channel-section steel positive identity distance center, outwards output respectively the elongated slot 7 of 10cm, width is 16mm left and right, with the hook 3 of two width 16mm, from elongated slot 7, pass, with nut 2, fasten, and can up-down adjustment length.
The present invention tentatively uses pungent the chatting on I II line N124 tower of 500kV at present, to adjust ground wire wire clamp offset problem.Operating personnel, by using this tangent tower to recheck job platform, can protect ground wire from lines very easily and take off, and ground wire and protect lines without any damage.Use this platform, the activity duration from before within 30 minutes, shorten to above 15 minutes, the method is simple to operate, has reduced labour intensity, has promoted efficiency, has shortened the activity duration, has also reduced operating risk simultaneously.This stage apparatus is simple in structure, and materials are few, and low cost of manufacture is economical and practical, meets the theory of " three save ".Equipment and personnel's coefficient of safety while adopting the present invention to improve maintenance, circuit lightning conducter defect more can be eliminated timely, sound assurance the stable operation of electrical network.
In sum, after adopting the present invention, operating personnel can remove and installment work protecting lines thereby carry out to lightning conducter lifting on ground wire cross-arm, and Heave Here is positioned at protects lines both sides, avoid lightning conducter and protect the wearing and tearing of lines, reduce the labour intensity of work high above the ground personnel on tower.
