Description
Technical field
The utility model belongs to transformer exterior line accessory technical field, and in particular to a kind of gold of the positive silk structure of band
Belong to bellows, be easily installed and dismantle and the paint film in damage two end flanges of bellows can be prevented.
Background technique
Metal bellows is commonly used in the connection of transformer pipeline, bellows plays the role of a soft readjustment, uses
To eliminate the error of production and installation process generation.Metal bellows is flexible, and can offset certain length direction and method
The nonconcentricity at blue both ends.Guo Wang company requires to be gradually increased to the nonconcentricity at ripple pipe flange both ends in recent years, bellows
Mainly play error on compensating length direction at present.
Since metal bellows is wavy metal, there is certain intensity, if assisted in actual installation process without tool,
Manually it is difficult that bellows is allowed to deform.When eliminating overgauge, need to be stretched to bellows by the attachment bolt of two end flanges
Position；When eliminating minus deviation, need gradually to be compressed bellows with crowbar etc. sled to installation site.Overgauge is unclamped in disassembly process
It is easy to remove after bolt；Minus deviation, which still needs, uses crowbar, gradually pulls out bellows.Bolt tension and the mistake for using crowbar
Cheng Zhong, the paint film on wavy metal pipe flange are easy destroyed, peeled off, and need again touch-up paint to handle after trial assembly, expend
Manpower and material resources.
Summary of the invention
In order to solve the above technical problems, the utility model designed on the flange at metal bellows both ends it is a certain number of fall
Positive silk structure is easily installed and dismantles in this way and not for adjusting the length of metal bellows during installation or removal
The paint film in two end flanges of metal bellows can be damaged.Technical solution used by the utility model is as follows:
A kind of metal bellows of the positive silk structure of band, comprising: be fixedly installed in flange one, the method at metal bellows both ends
Orchid two, the positive silk structure of at least two groups adjustable in length, the both ends of the positive silk structure respectively with flange one, flange two
It is fixedly connected.
When assembling metal bellows, actual installation dimension is first measured, then by adjusting positive silk structure by metal wave
The length adjustment of line pipe is to being slightly less than actual installation size, and after being installed in place, then the length by increasing positive silk structure is by wave
Line pipe be adjusted to actual size after, the attachment bolt of flange one that bellows both ends are fixedly mounted, flange two, finally by metal wave
Line pipe assembles in place.When dismantling metal bellows, the flange attachment bolt of bellows one end can be unclamped, first by adjusting just
Silk structure shortens the size of metal bellows, in order to dismantle.
Preferably, the positive silk structure include the left silk of screw rod, intermediate position be provided with circular hole fall forward leading nut, screw rod
Right silk, the internal screw thread of one end of forward leading nut matches for left silk, with the left silk of screw rod, the interior spiral shell of the other end of forward leading nut
Line is right silk, matches with the right silk of screw rod, intermediate circular hole be used for by auxiliary tool rotation forward leading nut increasing or
Shorten the length of positive silk structure and metal bellows.It, can be very by the ingenious cooperation of left and right screw rod and forward leading nut
Easily adjust the length of metal bellows.
Preferably, the left silk of the screw rod, the right silk of screw rod are fixedly connected with flange one, flange two respectively by welding, are made
The connection obtained therebetween is stronger.
Preferably, four groups of positive silk structures are circumferentially evenly equipped between the flange one, flange two, so that in operating process
Stress more balance, be stable, is powerful.
The utility model has the beneficial effects that
1) the utility model passes through simple positive silk structure, solves installation brought by the intensity because of metal bellows
With the inconvenience of disassembly, and the paint film in two end flanges of metal bellows will not be damaged, save man power and material.
2) the utility model structure is simple, input cost is low, it is very convenient to operate.

Specific embodiment
With reference to the accompanying drawing, the embodiments of the present invention is illustrated.
As shown in Figure 1, being the structural schematic diagram of existing metal bellows；As shown in Fig. 2, being the A of existing metal bellows
To cross-sectional view.In actual installation and disassembly process, if being difficult that bellows 2 is allowed to deform without tool indirect labor, if used
The auxiliary tools such as crowbar then may cause the flange one (1) of metal bellows, the paint film on flange two (3) is destroyed, occurred
It peels off.
As shown in figure 3, being the structural schematic diagram of the metal bellows of the positive silk structure of band；As shown in figure 4, being the positive silk of band
The A of the metal bellows of structure is to cross-sectional view；As shown in figure 5, being the length direction cross-sectional view of positive silk structure.In wavy metal
Between the flange one (1) at 2 both ends of pipe, flange two (3), devise four groups of positive silk structures, positive silk structure by the left silk 4 of screw rod,
The right silk 6 of forward leading nut 5, screw rod forms, wherein the right silk 6 of screw rod and the left silk 4 of screw rod are first assembled with forward leading nut 5, just
The internal screw thread of 5 one end of silk nut matches for left silk, with the left silk 4 of screw rod, and the internal screw thread of the other end of forward leading nut 5 is the right side
Silk and the right silk 6 of screw rod cooperate, and centre is the length that circular hole is used to rotate forward leading nut 5, the positive silk structure of adjustment.Screw rod is left
Silk 4, the right silk 6 of screw rod are fixedly connected with flange one (1), flange two (3) respectively by welding.It, first will positive silk in the present embodiment
The positive silk structure of level Four is welded to bellows two under metal bellows nature retracted position by the good size of structural adjustment
On the flange at end.When rotating clockwise intermediate nut, both sides screw thread is all inward into two end flanges of bellows being received
Tightly.Conversely, rotating counterclockwise, both sides are past simultaneously to go out, and bellows can be made to be in drawing and relax and stretch state.
Assemble metal bellows when, the actual installation size of first measuring bellow, then by rotation fall forward leading nut, will
Bellows Length is adjusted to be slightly less than actual installation size, fixes after being installed in place, then after bellows is adjusted to actual size
The flange attachment bolt at bellows both ends.When disassembly, the flange attachment bolt of bellows one end can be first unclamped, is fallen by rotation
Forward leading nut shortens ripple pipe size, in order to dismantle.
