Abstract
The utility model discloses a live spanning device, wherein the live spanning device comprises a first iron tower and a second iron tower, and each iron tower is equipped with a cross-arm. Two first temporary cross-arms are hung under the first iron tower cross-arm, and two second temporary cross-arms are hung under the second iron tower cross-arm; a double-layer pulley is hung under the first temporary cross-arms, and another double-layer pulley is hung under the second temporary cross-arms; two bearing ropes form a cableway by respectively connecting the upper pulleys of the double-layer pulleys with ground anchors; and glass fiber reinforced plastic pipes are uniformly hung under the two bearing ropes via pulley suspension hooks, and are positioned over spanned power lines. The live spanning device has the advantages of simple structure, convenient operation, short time, high efficiency and safe and reliable performance, and can carry out electric wire erection in a live state.
Description
Technical field
The utility model relates to charged paying-off implement field in power circuit process of construction, relates in particular to a kind of live across device.
Background technology
In power circuit engineering construction, inevitably run into the power circuit that has some to be crossed over, the one, before stringing, first the power circuit of being crossed over is had a power failure, will cause a lot of potential safety hazards like this, and the personnel that use are more, not only inconvenience but also dangerous; The 2nd, there are some power circuits of being crossed over not have a power failure, must live across.In addition, along with the development of economic construction, newly-built superelevation electricity transmission line acrossing highway, railway, industrial crops and other barriers are also more and more.In above situation, the construction method of setting up crossing frame can not be gathered effect, must solve by new leap technology this new problem.
Summary of the invention
Not enough for solving prior art, the utility model aim to provide a kind of simple in structure, easy to operate, the time is short, efficiency is high, safe and reliable, can in charged situation, carry out the live across device that electric wire sets up.
The utility model is achieved by the following technical solution: live across device, comprise the first steel tower, the second steel tower, the first described steel tower, the second steel tower is all provided with cross-arm, it is characterized in that: under the first described steel tower cross-arm, hang two the first temporary cross arms, under the second described steel tower cross-arm, hang two the second temporary cross arms, the first temporary cross arm, under the second temporary cross arm, hang respectively double-deck coaster, two carrying ropes are connected to earth anchor formation cableway by the upper pulley of double-deck coaster respectively, under two carrying ropes, by pulley suspension hook, be hung with equally distributed glass reinforced plastic pipe, described glass reinforced plastic pipe is positioned at the top that is surmounted power line.
Every described glass reinforced plastic pipe two ends are wound around respectively a circle pull rope successively by the lower block connection sheave of double-deck coaster.
Described fiberglass pipe range 8m is 5 meters of arranged with intervals under carrying rope.
The horizontal level of the second described temporary cross arm sets high 5m than the horizontal position of the first temporary cross arm.
Described carrying rope is the Di Nima rope of diameter 22mm.
Described pull rope is the Di Nima rope of diameter 10mm.
The length of described pulley suspension hook is 0.5m.
The utility model live across device use principle: hang two groups of (4) temporary cross arms under steel tower under cross-arm, under temporary cross arm, hang double-deck coaster, to carry rope and form cableway by coaster, carrying rope arranged with interval glass reinforced plastic pipe, it hangs under carrying rope by pulley suspension hook, and pulley is Buddhist nun's gram material.
That the utility model live across device has advantages of is simple in structure, easy to operate, the unwrapping wire time is short, efficiency is high, safe and reliable, can in charged situation, carry out electric wire and set up.
