Description
Technical field
The utility model relates to a kind of tools for live working, specifically a kind of compact line six-multiple conductor link plate clamping tool.
Background technology
In compact line, division number and the conventional line division number of wire are different, arrangement is divided in usual employing six, and namely every six roots of sensation sub-conductor is separately fixed in six through holes of six yoke plates by cylindrical arrangement, then the insulator string through being connected with six yoke plates is fixed on shaft tower.Because the safety operation of compact line is apart from smaller, particularly in high altitude localities 500kV compact line, be only 3.2m at the following earth potential of height above sea level 1000m and equal potential working minimum safe distance relatively, during equal potential working, alternate minimum safe distance is only 4.6m; Be only 3.4m at the above earth potential of height above sea level 1000m and equal potential working minimum safe distance relatively, during equal potential working, alternate minimum safe distance is only 5.0m.And when insulator string is damaged need to change time, is at present usually all take power failure operation mode to change, although fail safe is high, makes troubles to the life of people and the production of enterprise.
The Work tool that Chinese patent ZL 2,007 2 0085185.6 discloses a kind of compact line straight line bunch of insulator is Six-divided conductor hook, two Six-divided conductor hooks are used when changing compact linear string, total weight just reaches 40 kilograms, volume is large and heavy, effort is compared during transmission, and combinational gap is likely inadequate when the transmission of instrument, jeopardize the safety of staff, during conducting wire hook, operating personnel just needs to walk around insulator string, a thread hook is respectively installed in insulator string both sides, moving range is large, be unfavorable for the safe distance controlling live line working, and waste time and energy.
Said method and device thereof exist following four and implement a difficult problem:
1, operating personnel needs to pay larger labour intensity.Six-divided conductor hook volume is large, weight large, when instrument transport, carrying, needs many people to carry out the vehicle with larger space; In operation process, no matter be ground staff thread hook being passed to setting, or equal potential working personnel when mounted, all will pay the labour of high strength;
2, require high when instrument transmits to combinational gap.The general tower height of compact line is 30 meters to 50 meters, and Six-divided conductor hook is because volume is large, weight is large.When instrument transmits near tower window, need tail rope outside tower body, pull out the enough safe distances of certain distance guarantee.Therefore in transmittance process, operation is implemented to need landform residing for shaft tower to have 30 meters to 50 meters smooth landform commodiously and along on line direction, and most shaft tower cannot ensure this condition in mountain areas large residing for South-West Yunnan, the southeast of Guizhou Province, many south electric network compact line corridors such as Gui Xi, Gui Bei.
3, power tool, device, operation procedure are numerous and diverse.Said method is implemented to be formed by multi-mode operation instrument, device, Automatic manual transmission, and operation layout is multi-point and wide-ranging, and program is numerous and diverse, and operation process is careless slightly, likely causes the generation of personal injury or equipment breakdown.
4, during conducting wire hook, operating personnel just needs to walk around insulator string, respectively installs a thread hook in insulator string both sides, and moving range is large, is unfavorable for the safe distance controlling live line working, and wastes time and energy.
