Description
Technical field
The invention belongs to power industry construction of power transmission and transformation apparatus, particularly to a kind of transmission line of electricity split conductor sag adjustment instrument.
Background technology
220KV and above extra high voltage network, for long distance power transmission, and in order to reduce line reactance, every phase conductor uses more than 2 ~ 4 split conductors, and arrangement mode is various, and require that the spacing of homophase sub-conductor and sag are all identical, owing to construction and installation and operation changing difference, the spacing that sub-conductor occurs and sag is caused to change, affect transmission line of electricity properly functioning, adjusted the instruments such as sag many employings zipper calabash to operate in the past, its method is complicated, operator are many, use instrument is heavy, difficulty of construction is big, labor intensity increases.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, it is provided that a kind of instrument is light, and difficulty of construction is little, saves labor, safe and reliable transmission line of electricity split conductor sag adjustment instrument.
The present invention solves technical problem and the technical scheme is that transmission line of electricity split conductor sag adjustment instrument includes: tightener, alignment pin, connect bearing pin, adjustment plate, laborsaving leading screw, ratchet spanner, connecting plate, it is characterized in being provided with tightener boss on a horizontal edge of the tightener of triangle, tightener boss alignment pin is by card line boss Connection Card wire body, tightener is provided with the chute one of arc, chute one is coordinated with card wire body by sliding pin, long hypotenuse at tightener sets the chute two of arc, chute dual-purpose connects bearing pin and is flexibly connected with adjustment plate, on the long hypotenuse of tightener, middle spring base is equipped with back-moving spring, it is arranged above with spring shield at back-moving spring.
The invention has the beneficial effects as follows: transmission line of electricity split conductor sag adjustment instrument is light, reduce difficulty of construction, reduce operator's quantity, reduce the labor intensity of operator, operate safe and reliable.
Accompanying drawing explanation
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is transmission line of electricity split conductor sag adjustment tool construction figure.
In figure, 1-card wire body；1-1-card line boss；2-sliding pin；3-spring base；4-back-moving spring；5-connects bearing pin；6-adjustment plate；The laborsaving leading screw of 7-；8-ratchet spanner；9-connecting plate；10-spring shield；11-tightener；11-1-tightener boss；11-2-chute one；11-3-chute two；12-alignment pin；13-fastening bolt；14-clamp nut.
Detailed description of the invention
Embodiment, referring to the drawings 1, transmission line of electricity split conductor sag adjustment instrument is that left end is provided with tightener boss 11-1 in a horizontal sides of the tightener 11 of triangle, tightener boss 11-1 is by card line boss 1-1 alignment pin 12 Connection Card wire body 1, in the middle of tightener 11, chute one 11-2 that arc is arranged below of card wire body 1 correspondence, by sliding pin 2 Connection Card wire body 1 in chute one 11-2.Chute two 11-3 of arc it is provided with at a long hypotenuse of tightener 11, it is flexibly connected with adjustment plate 6 with connection bearing pin 5 in chute two 11-3, on the long hypotenuse of tightener 11, two spring bases 3 are fixed in middle, fill back-moving spring 4 between two spring bases 3, be arranged above with spring shield 10 at back-moving spring 4.Connecting the left end of laborsaving leading screw 7 in the right-hand member fastening bolt 13 of adjustment plate 6 and clamp nut 14, operate with ratchet spanner 8 on laborsaving leading screw 7, right-hand member fastening bolt 13 and clamp nut 14 at laborsaving leading screw 7 are connected with connecting plate 9.
The work process of transmission line of electricity split conductor sag adjustment instrument is: the right-hand member of tightener 11 connects adjustment plate 6, the other end is with connecting clamping wire between tightener boss 11-1 and card line boss 1-1, the size of sag is regulated with laborsaving leading screw 7 and ratchet spanner 8, only needing a people on adjustment sag work tower, the position that sag is slided in chute one 11-2 and chute two 11-3 by sliding pin 2 and connection bearing pin 5 determines.
