Abstract

The utility model relates to the technical field of an overhauling tool for overhauling an electric conductive part of a knife switch and a bearing pedestal of a middle porcelain knob in the field of an electrical power system, in particular to a middle porcelain knob displacement support for transforming a GW-7 knife switch. In the displacement support, a short screw stem and a long screw stem are connected at the lower part of an iron plate, and angle iron is connected onto the short screw stem and the long screw stem. The middle porcelain knob displacement support can completely replace the traditional operation mode of the existing holding rod slider, has the characteristics of safety in use, time saving, labor saving, simple structure and light weight, and has stronger practical performance.

Description

Porcelain knob displacement support in the middle of the GW-7 disconnecting link is transformed
Technical field
The utility model relates to the technical field of the service kit that a kind of electric power system overhauls disconnecting link current-carrying part and middle porcelain knob bearing pedestal, relate in particular to a kind of GW-7 disconnecting link transform in the middle of porcelain knob displacement support.
Background technology
There are 124 groups of GW-7 disconnecting links in 19 in existing 220KV electric substation of Shenyang Power Supply Co..All there are every year tens of groups of GW-7 disconnecting link current-carrying parts and middle porcelain knob bearing pedestal to overhaul and the improvement transformation.Because the place safe distance is limited, crane can't operation, can only hang slider with pole slings middle porcelain knob to land and carries out dismounting and change, this process needs 7 people to finish at least, every porcelain knob is heavy nearly 300 jin, and use all handy rope of pole to tie up at every turn, pretty troublesome, when the first three groups operation, once the dangerous situation that a pole sideslip occurred causes porcelain knob to damage and personnel's injury narrowly, and the activity duration reaches 9 hours, the transformation task of failing to finish in planned time has been handled work ticket extension formality and has been caused and send the electricity time-delay.
The utility model content
The utility model provides a kind of GW-7 disconnecting link to transform middle porcelain knob displacement support at above-mentioned problems of the prior art.Purpose be save time in order to provide a kind of, laborsaving, safe and reliable a kind of displacement support, it can replace the traditional work mode of existing pole slider.
The technical scheme that its technical problem that solves the utility model adopts is:
Porcelain knob displacement support in the middle of the GW-7 disconnecting link is transformed, it is to be connected with short screw and long bolt in the bottom of iron plate, all is connected with angle bar on short screw and the long bolt.
Described short screw links to each other with angle bar by nut with long bolt.
Described short screw is arranged with 4.
Described long bolt is arranged with 2 in the middle lower portion of iron plate.
Described iron plate is provided with four holes.
Described angle bar is provided with two holes.
The utility model can replace the traditional work mode of existing pole slider fully, has stronger Practical Performance, and it has following characteristics:
1, safety: this support is to be fixed on the disconnecting link channel-section steel, and the porcelain knob after the displacement can be fixed on not have at all on the support and rock with screw, and is very firm.
2, simple in structure: this support be with the thick 8mm of the wide 300mm of long 350mm iron-plated, above be drilled with 4 of screw rods, 2 of long 400mm diameter 16mm screw rods, the wide 50mm * 50mm of long 420mm of 4 holes identical and long 170mm diameter 16mm with flange at the bottom of the porcelain knob 3 in angle bar manufacture and form.
3, body is light: singlely can finish installation and removal.
4, laborsaving: as only to need two people just can easily to move on on this support by the porcelain knob that weight is nearly 300 jin.
5, save time: every porcelain knob shifting process less than 20 minutes.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the structural representation of angle bar in the utility model;
Fig. 4 is the structural representation of iron plate in the utility model.
Among the figure: iron plate 1, short screw 2, nut 3, angle bar 4, hole 5, disconnecting link base channel-section steel 6, long bolt 7.
Embodiment
Below in conjunction with specific embodiment of the utility model and accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 4, the utility model is a porcelain knob displacement support in the middle of the GW-7 disconnecting link is transformed, it is to be symmetrically connected with 4 short screws 2 in the bottom at four angles of iron plate 1, by two holes above the angle bar 4, two angle bar 4 are through respectively on two screw rods 2 of homonymy, pass through nut 3 in the top and the bottom of angle bar 4 again, angle bar 4 is connected with short screw 2.Also be provided with 4 holes 5 on the described iron plate 1.
Be symmetrically connected with 2 long bolts 7 in the bottom in iron plate 1 centre position, pierce into an angle bar 4 on the long bolt 7, and by nut angle bar 4 is movably connected on the long bolt 7 in the bottom of angle bar 4.
The utility model course of work is as follows:
At first, displacement carrier base described in the utility model on disconnecting link base channel-section steel 6, is come on the former base, it is consistent with former base to adjust height.
Angle bar 4 on the short screw 2 can be maintained fixed state after installing, only need during use through on the long bolt 7 angle bar 4, screwing nut 3 unclamps angle bar 4 and four Φ 16mm of flange screw at the bottom of support and the disconnecting link channel-section steel porcelain vase, pull down three screws, with the screw that stays is axle, each is being held up by a people up and down, the porcelain vase that is shifted is turned on the displacement support described in the utility model, any one hole is aimed at any one hole 5 on the displacement support iron plate 1 described in the utility model, put on screw and put on nut, former base screw is pulled down, serve as that axle rotates porcelain knob on the displacement support with the displacement rack screw again, its remaining three holes are overlapped with the hole 5 of displacement on the support put on screw and put on nut, former bearing pedestal is removed changed, time process of assembling opposite with it.The service test of displacement support described in the utility model by 60 groups of GW-7 disconnecting link improvements are transformed produces a desired effect.
