Embodiment
Below in conjunction with accompanying drawing, as example of making, technical scheme is further illustrated.
With reference to Fig. 1,2,3,4,5, form and change the two duplex overturning plate clamps 1 of going here and there in three parts of horizontal insulator instrument of 500kV straight line simply connected by turnover panel 14 and card 9, by rotating shaft 10, be rotationally connected formation; 9 axis holes of opening by the junction surface of mutual meshing form of turnover panel 14 and card penetrate rotating shaft 10 in axis hole, and axle lower end is fixed with pad and swivel nut, and rotating shaft 10 upper ends have a spindle nose that is greater than axis hole to make axle shelves.Consistent with turnover panel shape with turnover panel 14 anastomotic parts in card 9; The two in conjunction with after, between form a clip slot, the width of clip slot is slightly less than the duplex plate thickness of the insulator string of existing use, so that while using, duplex plate 21 is clamped in this clip slot.Central spot expense hole 12 in card 9 with turnover panel 14 assemblys, this pin-and-hole 12 runs through turnover panel 14; With 3 Screws, pad lid 13 is fixed in to pin-and-hole 12 places, then hexagonal (hexagon)nut 11 is fixed in to pad covers on 13.During use, the bolt head of duplex plate 21 one end, through the hexagonal (hexagon)nut 11 at pin-and-hole 12 places, is stuck in hexagonal (hexagon)nut 11; Screw the attachment screw at link plate 2 places of turnover panel 14 one end, allow card 9 and turnover panel 14 form clip slots duplex plate 21 is stretched into one end in its groove by firm grip, on replaceable duplex plate 21, be positioned at the insulator string 20 on this clamped one end.Be positioned at card 9 two ends perforates, each uses the affixed link plate 2 of screw, and link plate upper/lower terminal has connecting hole, and upper hole is connected with card 9, and lower hole is for connecting with adjustable insulating rod 3 or adjustable insulation board 23.During with adjustable insulation board 23, be the connecting hole 24 of selecting diverse location, the mode that changes its length reaches adjustable object, while selecting adjustable insulating rod 3, utilizes the insulating rod of different length to combine the requirement that realizes length.
The top that forms four line hooks 5 in three parts of replacing 500kV straight line simply connected two string horizontal insulator instrument is main body 16, make two ends a little less than middle part, middle part epirelief, and the size shape generous compared with two ends, two ends are manufactured with thread hook that the mouth of hook makes progress as rising to the bait 8; Two sides under 8 hook of rising to the bait make protuberance under a downward circular arc, in lower protuberance perforate, the shank that has thread hook by screw 17 each affixed lower ends, as lower hook 7, the length of shank should adapt in current electric power transmission tower the requirement of discrepancy in elevation size between upper twice of 22 liang, four wires.Central spot perforate in main body 16 top and bottom, can allow the screw mandrel 4 of worm and gear stretch out, then centered by the end opening in this hole, opens around four screws, with screw 18, worm and gear 6 is installed; The operation spanner 19 of worm and gear 6 adopts charging type electric wrench, is convenient to when changing insulator, laborsaving quick during operation worm and gear.In the upper end of worm and gear 4, be fixedly mounted with a connector 15 that has connecting hole, be convenient to be connected with adjustable insulating rod or adjustable insulation board.
Form the adjustable insulating rod of changing in three parts of 500kV straight line simply connected two string horizontal insulator instrument, the parts that this example is selected, by two sections, by joint screw, link together, then the link plate 2 in the card 9 of its upper end and duplex overturning plate clamp 1 is connected, connector 15 screws of the screw mandrel 4 of lower end and worm and gear are connected firmly.
With two four line hooks 5 and the adjustable insulating rod 3 of two covers, be connected with duplex overturning plate clamp 1 and make the two string of the 500kV straight line simply connected horizontal insulator instrument of changing.
With reference to Fig. 4, use while changing the two string of 500kV straight line simply connected horizontal insulator tool changing insulator string, operate as follows:
By being positioned at the bolt that turnover panel 14 outer ends are connected with link plate 2, take out, just can be turnover panel 14 along axle 10 rotating opening, insert afterwards one end of upper duplex plate 21, hex nut 11 is fastened on the hexagonal spiral shell of duplex plate 21 one end, turnover panel 14 closes, penetrate the connecting bolt of link plate 2 and card 9 and screw, duplex overturning plate clamp 1 is just clamped duplex plate 21.Again four transmission pressures 22 that are arranged in below are hung into two of four corresponding line hooks 5 hook 7 of rising to the bait 8 and twice, wire 22 gravity just all move to be changed on the two string of 500kV straight line simply connected horizontal insulator instrument, on replaceable duplex plate, is sandwiched in the insulator string 20 of this one end in duplex overturning plate clamp 1.After replacing finishes, then clamp in the same way the duplex plate other end, change the insulator string on the other end.What illustrate is the duplex plate 21 of using on transmission line, and the hanging hole at its upper convex portion center articulates with electric power pylon, and two ends respectively have an insulator string 20 to be connected by combination yoke plate with four wires 22 of below.
Specified operational procedure:
While 1, changing insulator string, after No. 1 electrician opens duplex overturning plate clamp turnover panel traveling nut, be arranged on the duplex plate 21 of insulator string to be replaced, the nut at keyhole 12 places, Bing Shi center is closely connected with duplex plate load bolt;
2, No. 1 electrician installs adjustable insulating rod 3 at connecting plate place, duplex overturning plate clamp both sides; After screwing, adjustable insulating rod 3 is fixed, and meanwhile, turnover panel 14 also clamps duplex plate 21;
3, No. 1 electrician and equipotential electrician are engaged in wire place four line hooks 5 are installed, and by equipotential electrician, worm and gear screw mandrel 4 are connected with adjustable insulating rod 3;
4, equipotential electrician utilizes electric wrench 19 to tighten up 4, four transmission pressure weight of screw mandrel to shift well on four line hooks 5, after waiting insulator string loose, coordinate No. 1 electrician to carry out the replacing of bunch of insulator.
So, can be used for changing the insulator string of different model and different length, this combination tool is easy for installation, simple to operate, effectively reduces power tool, reduces labour intensity, increases work efficiency and handling safety.
