Swollen silk is fixed on ground, and pilot hole is offered in fixed plate, and slide bar, the slide bar right end weldering are equipped in the pilot hole
Movable pulley rack is connected to, the movable pulley rack right side is welded with movable pulley by stent, and the fixed pulley yoke is consolidated by expansion thread
Due to movable pulley rack right side, fix on pulley yoke and fixed pulley is welded with by stent, and fixed pulley yoke rises by bar with moving by contracting
Pulley yoke is connected, and the clump weight is positioned over below movable pulley rack, and clump weight sequentially passes through movable pulley by drawstring, slides calmly
Wheel is connected with buffer spring.
Preferably, the contracting rises by bar as piston cylinder operator, and inside is filled with kerosene.
Preferably, the movable pulley is at least provided with 2, and the spacing between movable pulley is more than the two of the diameter of movable pulley
Times.
Preferably, the fixed pulley is at least provided with 2, and the spacing between fixed pulley is more than the two of the diameter of fixed pulley
Times.
Compared with prior art, the beneficial effects of the invention are as follows：The configuration of the present invention is simple, support arm one end are provided with pipe
Hoop, can arbitrarily adjust support arm height；Protective cover is arranged on link, effective protection cable sister block corrodes from the external world,
Rotation is influenced to use；Movable pulley rack is arranged in by slide bar in fixed plate, it is ensured that movable pulley rack lateral shuttle in fixed plate
It slides；Fixed pulley yoke is connected by the contracting bar that rises with movable pulley rack, can be risen in the case that bar expands with heat and contract with cold in contracting, be elongated or contract
The length of short drawstring drives cable tightening or loosens；Insulating sheath can effectively protect buffer spring is from external world's corrosion or is using
When surprisingly block set foreign materials away use.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Whole elaboration.
As shown in Figs. 1-3, it is a kind of to be suitable for field cable stringer, including support arm 1, fixed plate 2, fixed pulley yoke
3 and clump weight 15,1 one end of support arm electric pole top is mounted on by pipe collar 4,1 other end bottom of support arm is welded with
Link 5 is provided with cable sister block 6 and protective cover 8 on link 5, and cable sister block 6 is arranged in link 5 by shaft
It is interior, two cables 17 are staggeredly equipped on cable sister block 6 successively, the mutually winding of two cables 17 welds together, and cable
17 winding welds are arranged with porcelain insulator 7, and 7 bottom of porcelain insulator is connected with buffer spring 16, and 16 outside of buffer spring is arranged
There is insulating sheath 18, protective cover 8 is sheathed on 5 outside of link, and fixed plate 2 is fixed on by expansion thread on ground, fixed plate 2
On offer pilot hole 9, be equipped with slide bar 10 in pilot hole 9,10 right end of slide bar is welded with movable pulley rack 11, and movable pulley rack 11 is right
Side is welded with movable pulley 12 by stent, and fixed pulley yoke 3 is fixed on 11 right side of movable pulley rack, fixed pulley yoke by expansion thread
Fixed pulley 13 is welded with by stent on 3, and fixed pulley yoke 3 is connected by the contracting bar 14 that rises with movable pulley rack 11, clump weight
15 are positioned over 11 lower section of movable pulley rack, and clump weight 15 sequentially passes through movable pulley 12, fixed pulley 13 and buffer spring by drawstring
16 are connected.
Specifically used mode：When installing and using, the height of support arm 1 is adjusted, fixed by pipe collar 4 according to live geographical environment
