The time for shortening entire livewire work work, increase substantially working efficiency.
Detailed description of the invention
Fig. 1 is insulation branch-cut bridge device structure chart of the invention；
Fig. 2 is main line cable clamping interface structure chart.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
As shown in Figure 1, 2, insulation branch-cut bridge device include branch-cut bridge pedestal 1, main line cable clamping interface 2, adjustment bolt 3, caging bolt 4,
Leeched line hole 5, operating stick 6, the branch-cut bridge pedestal 1 are made of the aluminum alloy plate materials of L-type, the main line cable clamping interface 2 include trough 11,
Slot tail 12, the trough 11 are rectangular block, and a through-hole is set in the middle part of trough 11, and the slot tail 12 includes that two panels parallel vertical is fixed on
The iron plate 13 of 11 lower part of trough, in each built-in arc-shaped limit piece 7 in two iron plates, 13 inside, the adjustment bolt 3 passes through main line
The through-hole at 11 middle part of trough of cable clamping interface 2, main line cable clamping interface 2 is fixed on the riser in 1 left vertical direction of branch-cut bridge pedestal, institute
It states and opens up vertical leeched line hole 5 on the transverse slat of 1 right side horizontal direction of branch-cut bridge pedestal, in 1 right side horizontal direction transverse slat of branch-cut bridge pedestal
End open up a threaded hole and be connected to leeched line hole 5, can be by the leeched line in leeched line hole 5 in the 4 precession threaded hole of caging bolt
It compresses, the operating stick 6 is fixedly connected with the bottom surface of 1 right side horizontal direction transverse slat of branch-cut bridge pedestal.
Specific implementation can reinforce technical effect using following technical measures: arc-shaped limit piece 7 is made of elastic sheet metal,
Spring is set between arc-shaped limit piece 7 and iron plate 13；The adjustment bolt 3, caging bolt 4 end be equipped with convenient for rotation spiral shell
The handle of bolt；The operating stick 6 uses thread connecting mode with branch-cut bridge pedestal 1.
2 overall length of main line cable clamping interface (include adjustment bolt) is 80mm, width 90mm, groove depth 60mm, right using adjustment bolt 3
Main line cable clamping interface 2 is according to need of work adjustment direction.The diameter in leeched line hole 5 is 26mm, and caging bolt 4 is used to be secured across leeched line
The conducting wire in hole 5.Operating stick 6 can be divided into two sections, and every section length is 900mm, temporarily be adjusted according to the needs of use.
The application method of branch-cut bridge device in actual operation that insulate is as follows:
In more complicated route, operation electrician does not reach designated position in its insulation bucket, and passes through insulating protection
After measure, operating personnel can not be transmitted under safe distance is connect branch line, because being connect branch line is passing through different circuit
Live wire road in when, have the danger for touching different potentials route.
Branch-cut bridge device insulate when in use, by the cooperation in leeched line hole and caging bolt, lead will be connect or branch line is consolidated
It is fixed, the direction of main line cable clamping interface is then adjusted by adjustable bolt selection, on the main line for blocking live wire road, operation electricity
Work selects the length of insulating bar according to the distance of operation.Simple " route of triangle arrangement " is carried out across shielding line
When, below the alive circuit in safe distance, main line cable clamping interface is directly clamped among on the middle line of electrification, at this moment passes through insulation branch-cut bridge
Device is connect wire locations and is fixed by the main line for having electricity and to overlapped, and the two is in same potential areas, then grasps
Operation bucket arm vehicle carries out peeling and overlap joint work to setting, by operator, waits work to terminate, directly insulation branch-cut bridge device
Cable clamping interface taken out from main line.The method avoids needs when existing operation to be connect lead by manually pulling, and is easy
Cause operator while touching the main line in different potentials and connecing the danger that lead gets an electric shock.
For complicated route and when operation bucket cannot be introduced into suitable position, operation electrician consolidates the cable clamping interface for the branch-cut bridge device that insulate
After being scheduled on main line, rotation process bar and branch-cut bridge base-separation, then, operating personnel's replacement operation vehicle location, into suitable position
It sets, continues to complete livewire work；After the completion of operation, branch-cut bridge pedestal is separated into main line.
In addition to the implementation, the present invention can also have other embodiments, all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
