Description
Technical field
The present invention relates to a kind of adjustable double hook doubling device of transmission line of electricity.
Background technology
On ultra-high-tension power transmission line, in order to reduce the conductor corona energy loss that causes of electric discharge and the interference to communication, general
All over using split conductor to transmit electric power, in China, 220KV transmission line of electricity typically uses double bundle conductor, in order to prevent double division from leading
Sub-conductor between line the most mutually holds, collides and occurs under the action of the forces of the wind the phenomenon being wound around, typically at two sub-conductors
Between install conductor spacer additional, the length of conductor spacer designs generally according to the design pitch between split conductor.Conductor spacer is filled just
Time, it being usually and use rope ladder to be suspended on a root wire, operating personnel arrives installation site by climbing rope ladder, but two
Sub-conductor, under the action of gravity of staff and rope ladder itself, can pull open a certain distance (typically at 3-5m) up and down, if
It is not readily accessible to sub-conductor above, then operating personnel can be caused cannot to complete the installation of conductor spacer, prior art, general work
Personnel are the methods using shooting rope, utilize rope to pull back sub-conductor above, but the sub-success rate of shooting rope is low, and work
Personnel are difficult to firmly, and the installation effectiveness causing conductor spacer is low, and the labor intensity of staff is big.
Summary of the invention
It is an object of the invention to provide a kind of adjustable double hook doubling device of transmission line of electricity, utilize this device can be smooth
Realize drawing in of the distance between two sub-conductors, thus the installation of beneficially conductor spacer, improve conductor spacer installation effectiveness.
The present invention solves its technical problem and is adopted the technical scheme that: a kind of adjustable double hook of transmission line of electricity is the most traditional thread binding
Put, including telescopic insulating bar, inverted U body, micro-adjusting mechanism and Removable hook, be fixedly installed on the top of described telescopic insulating bar
One with the square latch of through hole；
Being symmetrically arranged with L-type plate on the two sides of described inverted U body, the length of described L-type plate is with described inverted U originally
The length of body is identical, arranges a cover plate, described L-type plate, cover plate and the side of described inverted U body at described L-type plate medial surface
Constituting a chute, arrange a fixed hook in one end of described chute, described micro-adjusting mechanism includes firm banking, rotary shaft and shakes
, described firm banking is fixedly installed on upper position, the described inverted U body back side, and described rotary shaft was nested with at the described fixing end
In seat, described crank is arranged on the one end of described rotary shaft, and described Removable hook includes hook head and hook bar, described hook
Head is arranged on linked up with bar, and described hook bar is nested with in described chute, and described Removable hook is with described fixed hook phase
Right, described hook bar arranges a tooth bar being distributed along its length, and described tooth bar is positioned at cover plate with described inverted U originally
Between the side of body, described rotary shaft is provided with the travelling gear matched with described tooth bar；
At the described inverted U body back side, upper position arranges a square groove matched with described square latch, and in institute
State and on square groove, offer through hole；
In described rotary shaft, one ratchet is set near one end of crank, described inverted U body is arranged one with described spine
The ratchet that wheel matches.
Preferably, the hook head on described Removable hook is identical and described with the hook head structure on described fixed hook
Distance between the bending center of the hook head on Removable hook and the inner side of the hook head on described fixed hook bending part
For S, 20cm≤S≤60cm.
Further, the hook head on described Removable hook and the hook head inside bent portion on described fixed hook

1, present configuration is simple and convenient to operate, and in practical work process, staff utilizes the present invention can be real smoothly
Now separate the close of two transmission lines of electricity farther out, in order to install smoothly between two transmission lines of electricity and have between certain length
Every rod；When utilize rope further two transmission lines of electricity time, pull near after two transmission lines of electricity near rope place also
Not parallel, the fixture so causing space bar two ends to be parallel to each other can not snap on transmission line of electricity smoothly, needs staff
Holding transmission line of electricity and do somewhat furnishing, just can snap in fixture, so installing to conductor spacer makes troubles, and when utilizing the present invention
After fixing for two transmission lines of electricity, it is parallel to each other at two two transmission lines of electricity between Removable hook and fixed hook,
The fixture at conductor spacer two ends is so conducive to snap into smoothly on transmission line of electricity；
2, according to environment and Transmission Line Design requirement in the ground of transmission line of electricity, the regular length of conductor spacer is not one
Causing, in actual application, some conductor spacer length is a little and some conductor spacers is shorter, utilizes the micro-adjusting mechanism in the present invention can be real
The spacing of existing Removable hook and fixed hook adjusts, thus can realize the smooth installation of different length conductor spacer, further,
For making the distance between Removable hook and fixed hook accurately meet the length of conductor spacer, here, be on the cover board provided with shifting
Dynamic scale mark, shift scale labelling can accurately reflect the distance between Removable hook and fixed hook, thus favorably use work
Personnel determine the standoff distance of two transmission lines of electricity.
3, the air vent arranged on the inverted U body back side, has utilization to reduce under strong wind operating condition, inverted U body
Suffered wind-force, thus beneficially staff manipulates telescopic insulating bar smoothly, in order to Removable hook snaps onto power transmission line smoothly
Lu Shang, the installation for conductor spacer is provided convenience.
