Abstract
The invention belongs to power transmission and transformation tools in the electric power industry, and particularly relates to a power transmission line bundled connector sag adjustment tool. The power transmission line bundled connector sag adjustment tool comprises a wire grip (11), a positioning pin (12), a connecting hinge pin (5), an adjustment plate (6), a labor saving lead screw (7), a ratchet wheel spanner (8) and a connecting plate (9). A wire grip boss (11-1) is arranged on a horizontal edge of the triangular wire grip (11) and connected with a wire clamping body (1) by means of the positioning pin (12) and through a wire clamping boss (1-1). An arc-shaped first sliding groove (11-2) is formed in the wire grip (11). An arc-shaped second sliding groove (11-3) is formed in the long inclined edge of the wire grip (11) and is movably connected with the adjustment plate through the connecting hinge pin (5). A reset spring (4) is arranged in the middle of the long inclined edge of the wire grip (11) through a spring base (3). A spring cover (10) is arranged on the upper face of the reset spring (4). The power transmission line bundled connector sag adjustment tool is light in weight and convenient to use, the construction difficulty is lowered, the number of operators is lowered, and operation is safe and reliable.
Description
Technical field
The invention belongs to power industry construction of power transmission and transformation apparatus, particularly a kind of transmission line bundle 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 adopts more than 2 ~ 4 bundle conductor, and arrangement mode is various, and it is all identical requiring the spacing of homophase sub-conductor and sag, due to construction and installation and variation difference in service, cause occurring that the spacing of sub-conductor and sag change, affecting transmission line normally moves, adjusted sag adopts the instruments such as zipper calabash to operate more in the past, its method complexity, operating personnel are many, use instrument heaviness, difficulty of construction is large, labour intensity increases.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of instrument light, difficulty of construction is little, saves labor, safe and reliable transmission line bundle conductor sag adjustment instrument.
The technical scheme that technical solution problem of the present invention adopts is: transmission line bundle conductor sag adjustment instrument comprises: wire grip, alignment pin, connect bearing pin, adjust plate, laborsaving leading screw, ratchet spanner, connecting plate, be characterized in being provided with wire grip boss on a horizontal edge of leg-of-mutton wire grip, wire grip boss passes through card line boss Connection Card line body with alignment pin, on wire grip, be provided with the chute one of arc, chute one coordinates with card line body by sliding pin, establish the chute two of arc at the long hypotenuse of wire grip, chute dual-purpose connects bearing pin and is flexibly connected with adjustment plate, on the long hypotenuse of wire grip, back-moving spring is equipped with spring base in middle, on back-moving spring, be provided with spring shield.
The invention has the beneficial effects as follows: transmission line bundle conductor sag adjustment instrument is light, reduce difficulty of construction, reduce operating personnel's quantity, reduce operating personnel's labour intensity, handling safety is reliable.
Accompanying drawing explanation
