Description

500kV jumper string wire clamp thread-lifting hook
Technical field
The utility model relates in transmission line the technical field of tools changing wire jumper insulator, especially changes the instrument of 500kV jumper string side of wire first insulator.
Background technology
In prior art, when changing 500kV jumper string side of wire first insulator, normally with chain block by jumper string, weight and wire Integral lifting, change when jumper string relaxes, be not also specifically designed to the specific purpose tool changing jumper string side of wire first insulator at present.Owing to using chain block in prior art, need the instrument such as upper and lower steel bushing, upper lower block, lifting rope (tower head is to ground level) to coordinate, instrument is more, heavily about 28kg, is not easy to hill path transport and more changes jobs, also can consume operating personnel physical in a large number; More based on instrument, cause each stress point, corner block, rope complicated layout, operation time is long; Because chain block needs jumper string (500kV jumper string is generally 34 insulators, is about 5 meters), weight and wire Integral lifting, chain stroke is long, no matter is tighten up and loosen, all needs the more time; Lifting rope desirably dough figurine person 3 people controls, and adds high-altitude personnel 2 people, so this operation at least needs 5 people.In a word due to the method instrument more heavier, to prepare and the operating time grow, takes time and effort, needs personnel more etc., seem when replacing jumper string side of wire first insulator bothers very much, is unfavorable for more changing jobs and work high above the ground.
Summary of the invention
The purpose of this utility model provides a kind of light, small and exquisite, quick, efficient 500kV jumper string side of wire first insulator to change instrument to overcome above-mentioned the deficiencies in the prior art just, is specially 500kV jumper string wire clamp thread-lifting hook.
The purpose of this utility model is achieved by the following technical solution.
500kV jumper string wire clamp thread-lifting hook, to include bottom the chevron pinnacle portal frame stressed member be bent to form by a Metallic rod, the side lever being arranged at transverse support bar in stressed member portal frame bottom chevron, stressed member portal frame both sides one section and is bent outwardly 360 ° of U-shaped hooks formed, the safety plug be sleeved on U-shaped hook, is installed on the nut of U-shaped hook free end backstop on safety plug.
The angle α on the utility model stressed member chevron pinnacle is 120 °, and the interior angle β between the slope section on chevron pinnacle and the side lever of portal frame is 120 °.
The utility model structure is simple, light small and exquisite, when operation uses, coordinate simply with thread-tightening lead screw and insulator clamp apparatus, the instrument such as steel bushing, coaster, lifting rope is not needed to coordinate, only need 2 people just outfit can be carried upper tower and complete replacing insulator work, a large amount of instrument and 3 operating personnels can be reduced.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of safety plug in the utility model;
Fig. 4 is the schematic diagram that the utility model is assembled on thread-tightening lead screw;
Fig. 5 is schematic diagram when utilizing the utility model replacing 500kV jumper string side of wire first insulator.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model to include bottom the chevron pinnacle portal frame stressed member 1 be bent to form by a Metallic rod, the side lever being arranged at transverse support bar 2 in stressed member portal frame bottom chevron, stressed member portal frame both sides one section and is bent outwardly 360 ° of U-shaped hooks 6 formed, the safety plug 3 be sleeved on U-shaped hook 6, is installed on the nut 4 of U-shaped hook 6 free end backstop on safety plug 3.The angle α on stressed member chevron pinnacle is 120 °, and the interior angle β between the slope section on chevron pinnacle and the side lever of portal frame is 120 °.
The utility model can make as follows.First by diameter 16mm, the high strength round steel bent intermediate of long 120cm becomes ∠ 120 °, form the angle α on chevron pinnacle, again centre is bent to ∠ 120 ° to 12cm place, both sides, i.e. angle β, then inside for two ends 13cm place is bent to the U-shaped hook 6 that diameter is 10cm, as main stress part 1, then using in the portal frame that the high strength round steel of diameter 16mm is welded on main stress part 1 as support bar 2, be that 4mm steel plate cuts into two safety plugs and makes a call to 2 Ф 17.5mm eyelets 5 above with thickness, safety plug 3 is penetrated main stress part 1, finally by fastening for nut 4.
When adopting the utility model to change 500kV jumper string side of wire first insulator, as shown in Figure 4, Figure 5, two U-shaped hook portions of the present utility model are separately fixed on the wire clamp 7 of two upper sub-conductors, and safety plug is fastening, then by insulator clamp apparatus 8 and thread-tightening lead screw 9 installation in position, again chevron pinnacle, the utility model upper end place is connected with thread-tightening lead screw, thread-tightening lead screw is tightened up after each portion connects, until have free gap between side of wire first insulation 10 and connecting bowl head 11, now just old insulator can be taken off.In like manner, during new insulator carry, operate by same procedure.
Adopt the utility model, only need 2 people just outfit can be carried upper tower and complete replacing insulator work, a large amount of instrument and 3 operating personnels can be reduced.The insulator promoted needed for thread-tightening lead screw is only 4, promotes compared with in the of 34, substantially reduce job area with original cucurbit, significantly can shorten the activity duration.The most key is that the method job area is little, is only 4 insulators, thus effectively ensure that secured electrical gap, can be used for carrying out live line working, fills up the blank not being specifically designed at present and changing jumper string side of wire first insulator specific purpose tool.
