Abstract
The invention relates to the technical field of an overhauling tool for overhauling a conductive part and a middle knob insulator bearing support of an isolator in a power system, in particular to an improved middle knob insulator shifting bracket for a GW-7 isolator. The lower part of an iron plate is connected with a short screw and a long screw. Both the short screw and the long screw are connected with angle irons. The improved middle knob insulator shifting bracket for the GW-7 isolator can completely replace the conventional operating mode of the existing pole slider, has the characteristics of using safety, time saving, labor saving, simple structure and light weight and has a strong practical performance.
Description
Technical field
The technical field that the present invention relates to the service kit that a kind of electric power system overhauls disconnecting link current-carrying part and middle porcelain knob bearing pedestal, relates in particular to a kind of GW-7 disconnecting link transformation middle porcelain knob displacement support.
Background technology
, there are 124 groups of GW-7 disconnecting links in 19, existing 220KV electric substation of Shenyang Power Supply Co..There are every year tens of groups of GW-7 disconnecting link current-carrying parts and middle porcelain knob bearing pedestal to overhaul and improvement transformation.Because place safe distance is limited, crane cannot operation, can only hang slider with pole slings middle porcelain knob to land and carries out dismounting and change, this process at least needs 7 people to complete, every porcelain knob is heavy nearly 300 jin, and use at every turn pole all handy rope tie up, pretty troublesome, when first three groups operation, once the dangerous situation that occurred a pole sideslip, causes porcelain knob to damage and personnel's injury narrowly, and the activity duration reaches 9 hours, in planned time, could not complete transformation task, handle work ticket extension formality and caused power transmission time delay.
content of the present invention
The present invention is directed to above-mentioned problems of the prior art, a kind of GW-7 disconnecting link transformation middle porcelain knob displacement support is provided.Object be in order to provide a kind of, save time, laborsaving, safe and reliable a kind of shifting bracket, it can replace the traditional work mode of existing pole slider.
The technical solution adopted for the present invention to solve the technical problems is:
GW-7 disconnecting link transformation middle porcelain knob displacement support, it is to be connected with short screw and long bolt in the bottom of iron plate, is all connected with angle bar on short screw and long bolt.
Described short screw is connected 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 present invention can replace the traditional work mode of existing pole slider completely, has stronger Practical Performance, and it has following features:
1, safety: this support is to be fixed on disconnecting link channel-section steel, and the porcelain knob after displacement can be screwed on support and not have at all and rock, very firm.
2, simple in structure: this support is that 3, the angle bar of iron-plated, 4 of screw rods being drilled with 4 holes identical with flange at the bottom of porcelain knob and long 170mm diameter 16mm above with the thick 8mm of the wide 300mm of long 350mm, 2 of long 400mm diameter 16mm screw rods, the wide 50mm * 50mm of long 420mm is manufactured and formed.
3, body is light: singlely can complete installation and removal.
4, laborsaving: only to need two people just the porcelain knob of nearly 300 jin of weight easily can be moved on on this support.
5, save time: every knob insulator shifting process less than 20 minutes.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the structural representation of angle bar in the present invention;
Fig. 4 is the structural representation of iron plate in the present invention.
In figure: iron plate 1, short screw 2, nut 3, angle bar 4, hole 5, switch base channel-section steel 6, long bolt 7.
Embodiment
Below in conjunction with specific embodiments of the invention and accompanying drawing, the present invention is described in detail.
As shown in Figures 1 to 4, the present invention is GW-7 disconnecting link transformation middle porcelain knob displacement support, it is to be symmetrically connected with 4 short screws 2 in the bottom at four angles of iron plate 1, by angle bar 4 two holes above, two angle bar 4 are through respectively on two screw rods 2 of homonymy, in the top and the bottom of angle bar 4, pass through nut 3 again, angle bar 4 is connected with short screw 2.On described iron plate 1, be also provided with 4 holes 5.
In the bottom in iron plate 1 centre position, be symmetrically connected with 2 long bolts 7, on long bolt 7, pierce into an angle bar 4, and angle bar 4 is movably connected on long bolt 7 by nut in the bottom of angle bar 4.
The course of work of the present invention is as follows:
First, shifting bracket seat of the present invention, on switch base channel-section steel 6, is come on former base, adjust height consistent with former base.
Angle bar 4 on short screw 2 can keep stationary state after installing, only need be by angle bar 4 through on long bolt 7 during use, screwing nut 3 unclamps angle bar 4 and four Φ 16mm screws of flange at the bottom of support and disconnecting link channel-section steel porcelain vase, pull down three screws, the screw staying of take is axle, each is being held up by a people up and down, the porcelain vase being shifted is turned on shifting bracket of the present invention, make at the bottom of disconnecting link channel-section steel porcelain vase any one hole on flange aim at any one hole 5 on shifting bracket iron plate 1 of the present invention, put on screw and put on nut, former base screw is pulled down, the shifting bracket screw of take again rotates porcelain knob as axle on shifting bracket, its remaining three holes are overlapped with hole 5 on shifting bracket put on screw to put on nut, former bearing pedestal is removed and changed, return the contrary with it of process of assembling.Shifting bracket of the present invention, by the service test to 60 groups of GW-7 disconnecting link improvement transformations, produces a desired effect.
