Rate is low, high cost, and unsightly, the difficult control of installation quality easily occurs electric discharge galvanic corrosion strand broking.
Content of the invention
Technical problem to be solved in the utility model be to provide a kind of double cable of Ultra-high Voltage Substations OPGW single poles draw lower tight
It is fixedly mounted with and puts, effectively improves the double cables of Ultra-high Voltage Substations OPGW and draw lower integration fastening mounting process, it is ensured that construction and installation
Quality, reduces occupancy body of rod area, facilitates and step on bar operation service work, improves the operation ratio under double cables draw with bar.
For solving above-mentioned technical problem, the technical scheme adopted by the utility model is：
A kind of double cables of Ultra-high Voltage Substations OPGW single poles draw lower fastener, and including locking anchor ear, locking anchor ear is provided with
Multiple pillar mounting seats, in each pillar mounting seat, longitudinally-moving is connected with insulation column, and insulation column is provided with that to draw lower cable tight
Gu mechanism.
The locking anchor ear includes upper half circular boop, lower half circular boop, and upper half circular boop, lower half circular boop one end are by active section activity
Connection, the other end are locked by fastening bolt.
Multiple regulating bolts are separately installed with the upper half circular boop, lower half circular boop, and regulating bolt termination is provided with arc block.
The arcwall face of the arc block is provided with anti-slip rubber.
The pillar mounting seat is provided with internal thread hole, and insulation column is threadedly coupled with pillar mounting seat.
Arc waterproof washer is cased between the pillar mounting seat and insulation column.
Described draw lower cable retention mechanism and include drawing lower cable fastener, draw lower cable fastener and locked by clamping screw.
A kind of double cables of Ultra-high Voltage Substations OPGW single poles of the utility model draw lower fastener, with following technique effect：
1）, 2 insulation columns are installed using on an anchor ear, not only reduce engineering construction cost, and bar can be removed from
Upper adjustment cable and the installing space of the installing space of cable, cable and the body of rod.In addition, being also convenient for stepping on bar operation service work, improve
Double cables draw with bar under operation ratio.
2）, using cable insulation column and anchor ear right angle setting, for using on the body of rod in the big bar footpath of super-pressure, occupancy bar
Body space is little, and has prevented OPGW optical cables because fastening the insecure de- cable problem for causing, and reduces O＆M cost.
3）, be threadedly coupled with insulation column using pillar mounting seat, facilitate Assembling, transport, change and keep in repair, improve
The operating efficiency of operation on live bar, assembles simple and direct, easy construction.
4）, prevented OPGW and drawn lower cable that the stranded problem of electric discharge galvanic corrosion occurs.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the scheme of installation of regulating bolt in the utility model.
Fig. 3 is the schematic diagram of waterproof washer in the utility model.
In figure：Locking anchor ear 1, pillar mounting seat 2, insulation column 3 draw lower cable retention mechanism 4, active section 5, fastening bolt
6, regulating bolt 7, arc block 8, anti-slip rubber 9 draw lower cable fastener 10, clamping screw 11, arc waterproof washer 12.
Specific embodiment
As Figure 1-3, a kind of double cables of Ultra-high Voltage Substations OPGW single poles draw lower fastener, including locking anchor ear 1, institute
Stating locking anchor ear 1 includes upper half circular boop, lower half circular boop, and upper half circular boop, lower half circular boop one end be flexibly connected by active section 5, separately
Locked by fastening bolt 6 one end.Two pillar mounting seats 2 are provided with side by side on locking anchor ear 1, between two pillar mounting seats
Spacing is configured according to actual needs, so, eliminate for originally independent fastener on bar adjustment cable with
Bar, the installing space between cable and cable, it is ensured that construction quality.In each pillar mounting seat 2 described, longitudinally-moving is connected with absolutely
Edge pillar 3, insulation column 3 are provided with and draw lower cable retention mechanism 4, described draw lower cable retention mechanism 4 and include drawing lower cable fastener 10,
Draw lower cable fastener 10 to lock by clamping screw 11.So, by drawing lower one to the double cables of Ultra-high Voltage Substations OPGW terminals
Change assembly apparatus, reduce work operations amount on bar, so as to improve the workpiece efficiency of site operation installation.In addition, adopting
Anchor ear+draw lower cable retention mechanism, realizes the locking of bar, cable and fastener, and it is little not only take up body of rod space, and prevents
OPGW optical cables are because fastening the insecure de- cable problem for causing.
Multiple regulating bolts 7 are separately installed with the upper half circular boop, lower half circular boop, and 7 termination of regulating bolt passes through bolt
It is fixed with arc block 8.The arcwall face of the arc block 8 is provided with anti-slip rubber 9.Thus structure, when shank diameter in transformer station
When different, regulating bolt 7 can be passed through and arc block 8 adjusts locking.In addition, improving what arc block was connected with bar by anti-slip rubber
Compactness, it is ensured that do not release.The use range that double cables draw lower fastener can be expanded using this mechanism, versatility is improved.
The pillar mounting seat 2 is provided with internal thread hole, and insulation column 3 is threadedly coupled with pillar mounting seat 2.Thus tie
Structure, conveniently can dismantle and Assembling fixing device.In addition, according to the antifouling rank of transformer station's area surroundings, may be selected to exchange
The insulation column of corresponding level.
Arc waterproof washer 12 is cased between the pillar mounting seat 2 and insulation column 3.Arc waterproof washer 12 is rubber
Or metallic gasket is constituted, thus structure, can prevent threaded connection rust dead, cause the later stage to be changed difficult.
Operation principle and process：First, by insulation column 3 in pillar mounting seat 2；Then, locking anchor ear 1 is pacified
It is mounted in transformer station's interior bar, is locked using fastening bolt 6, when shank diameter is less in transformer station, can be revolved by regulating bolt 7
Enter and lock；Finally, just two cables are respectively put into and draw in lower cable fastener 10, are tightened by clamping screw 11.Due to
During this, original two single fasteners are incorporated in one above, engineering construction cost are reduced, is made construction more
Convenient.
