Cost.
Reference picture 1, Fig. 6 and Fig. 7, shackle are self-locking ring 4, and self-locking ring 4 includes canned paragraph 40 and self-locking section 41, self-locking section 41
It is hinged with canned paragraph 40, self-locking section 41 combines circular under the effect of the elastic force of spring 42 with canned paragraph 40, makes the natural shape of self-locking ring 4
Closure state is under state, canned paragraph 40 stops that self-locking section 41 departs from the circle of the two composition under the effect of the elastic force of spring 42.It is excellent
Selection of land, the profile of self-locking ring 4 and its cross section are circle, and can so reduce to a certain extent damaged in upkeep operation built on stilts keep away
The probability of thunder line, improves upkeep operation security and success rate.By setting the self-locking ring 4 can be by rotating first rotating arm 2
Directly overhead ground wire is hooked into shackle with the second turning arm 3, maked somebody a mere figurehead without manually climbing to hook at the position of self-locking ring 4
Lightning conducter, it is convenient to hook, laborsaving, after overhead ground wire is hooked into shackle, and self-locking ring 4 can prevent that overhead ground wire from taking off
Fall, it is ensured that upkeep operation reliability and security.Preferably, self-locking section 41 is located at the side of annulus, self-locking section 41 and canned paragraph
40 outmost turns arc length ratios are 1:3.Self-locking section 41 is located at the side of annulus, and built on stilts keep away is being hooked by rotating the second turning arm 3
More facilitate during thunder line, self-locking section 41 is 1 with the outmost turns arc length ratio of canned paragraph 40:3, it on the one hand can ensure canned paragraph 40
Intensity, the opening that on the other hand can also ensure self-locking section 41 can open facilitates the turnover of overhead ground wire.Preferably, self-locking
It is threadedly coupled between ring 4 and the second turning arm 3, so can easily changes the direction of self-locking section 41, can be while convenient hanger
Hang the overhead ground wire of both sides at the top of high-voltage power transmission tower.
Reference picture 1, Fig. 6 and Fig. 7, self-locking section 41 are provided with bracing wire hole 43.Setting bracing wire hole 43 can be by tying up to bracing wire
Bracing wire 44 in hole 43 pulls self-locking section 41, opens self-locking ring 4, then can by rotating the turning arm 3 of first rotating arm 2 and second
So that overhead ground wire is extracted out of self-locking ring 4, without manually climbing to overhead ground wire at the position of self-locking ring 4 from self-locking ring
Extracted in 4, manpower can be saved, improve the efficiency of operation.
Reference picture 1, Fig. 6 and Fig. 7, the second turning arm 3 is provided with two draw rings 6.Overhead ground wire is hooked into shackle
Overhauled afterwards, it is necessary to rotate the turning arm 3 of first rotating arm 2 and second and land overhead ground wire, set and draw on the second turning arm 3
Ring 6 can be conveniently lanyard rope 61.Preferably, two draw rings 6 are located at the top of the second turning arm 3, two 6 pairs of draw rings to distribution,
Using rope 61 respectively from two layback draw rings 6, the second turning arm 3 can be smoothly pulled, it is safe.
Reference picture 1, Fig. 6 and Fig. 7, the second turning arm 3 are provided with two changes 7 of the inlay card on the second turning arm 3, two
Change 7 is hinged with the second turning arm 3, and two changes 7 are connected by screw to form whole annulus by two semi-rings, two changes
Draw ring 6 is respectively equipped with 7.Two changes 7 are two semi-rings and combined, what combination can be connected by screw or weld
Mode realizes that two changes 7 are rotated around relative to the length-wise axis of the second turning arm 3, and such draw ring 6 can be around the second rotation
Arm 3 is rotated, and when pulling the second turning arm 3 to rotate by draw ring 6 using rope 61, rope can be ensured by the rotation of change 7
The direction of pull of rope 61 is consistent with the direction of draw ring 6 all the time, it is to avoid the pulling force during fixation of draw ring 6 occur, can perpendicular to the situation of draw ring 6
To improve the stressing conditions of draw ring 6, it is to avoid draw ring 6 is damaged, and then improve the security of device reliability and upkeep operation.
Reference picture 1 and Fig. 3, fixed seat are hook plate 1, and hook plate 1 is square, and 1 one right-angle side ends of hook plate are hook Ka Jiao
The hook-like configuration on the one side of steel 12, another right-angle side of hook plate 1, which is provided with, runs through the screwed hole and apical grafting vertical while with this
Bolt 11, apical grafting bolt 11 is screwed togather through screwed hole with hook plate 1.Hook plate 1 is stuck in one side of angle steel 12 by the hook-type hook of side
On, the apical grafting of apical grafting bolt 11 on another right-angle side of hook plate 1, can be firmly by hook on the corresponding right-angle side of angle steel 12
Plate 1 is limited on transmission tower, is fixed conveniently, reliably.It is appreciated that such a structure of hook plate 1 is also applied on channel-section steel simultaneously
Fixation, have a wide range of application.Certain fixed seat can also wrap up consolidating for transmission tower angle steel 12 using two larger angle steel 12
Determine mode.
Use process：
Hook plate 1 is installed on the angle steel 12 of transmission tower or channel-section steel, rope 61 and bracing wire 44 are tied up into the He of draw ring 6 respectively
On bracing wire hole 43, the length of first rotating arm 2 is adjusted by the screw rod 20 and sleeve 21 of first rotating arm 2, makes the height of shackle
