Description
Technical field
The present invention relates to a kind of iron core of electric reactor and compress technology and hold down gag.
Background technology
In the iron core of electric reactor compaction process,, behind mounting coil, need to use hollow jack pair upper yoke unshakable in one's determination to exert pressure to tighten up coil in order to control height unshakable in one's determination.Because reactor specification difference, institute's applied pressure is different when tightening up coil, and the tonnage that therefore tightens up the used hollow jack of coil also is different.Compress the most frequently used jack below 100 tons of coil, and for large-scale reactor, can need to apply the pressure more than 100 tons, the tonnage of the jack of outfit should be more than 100 tons.But the producer of production large-tonnage jack more than 100 tons seldom even if having, also not from stock, after having bought, owing to seldom use, just may leave unused for a long time on the market, wastes device resource.
Summary of the invention
In order to solve the idle device resource waste that brings of large-tonnage jack, the invention provides a kind of with little generation big iron core of electric reactor compress technology, be about to little tonnage jack below 100 tons and play the technique effect that large-tonnage jack compresses by the ingenious combination of a kind of hold down gag.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of iron core of electric reactor compresses technology, comprises the steps:
The first step uprightly is fixed on screw rod on the lower yoke, and after the reactor assembling, upper yoke and screw rod junction screw with nut;
Second step: pressure transfer device is penetrated screw rod to contacting upper yoke;
The 3rd step placed a lower platen on the pressure transfer device by screw rod, and 2 leads are set on lower platen at least, the relative screw rod symmetric arrangement of lead or evenly arrange along the screw rod periphery; A hollow jack of little tonnage all is set on each lead, jack is fastening with the top board that structure size is identical with lower platen by transition nuts;
In the 4th step, to each jack hydraulic system fuel feeding simultaneously, jack acts on downwards,, and pressure is acted on the coil coil is compressed to upper yoke by lower platen, pressure transfer device, at this moment, the slit occurs between nut and the upper yoke, screws nut;
The 5th step, remove transition nuts, top board, jack, lower platen, pressure transfer device successively at last after, wholely compress work and finish.
In the above-mentioned operation, described pressure transfer device is a sleeve, upper end closed, and the side has fenestra, is used to screw nut.Described lead is provided with 3 to 6, corresponding 3 to 6 the hollow jack of little tonnage is set.
According to the above a kind of hold down gag that compresses the technology use, comprise pressure transfer device and device for exerting, it is characterized in that described pressure transfer device contacts with upper yoke by the screw rod that vertically is fixed on the reactor lower yoke, upper yoke and screw rod junction are fastened with nut; Described device for exerting comprises upper and lower two block pressur plates, places on the pressure transfer device by screw rod, and 2 leads are set between the upper and lower pressing plate at least, the relative screw rod symmetric arrangement of lead or evenly arrange along the screw rod periphery; A hollow jack of little tonnage all is set on each lead, and top board is fastening with jack by a transition nuts.
In the said apparatus, described pressure transfer device is a sleeve, upper end closed, and the side has fenestra, is used to screw nut.Described lead is provided with 3 to 6, corresponding 3 to 6 the hollow jack of little tonnage is set.
Advantage of the present invention is, simple in structure, easy to use, low processing cost, and according to required jack tonnage and existing little jack tonnage, the little jack quantity of flexible combination can be more than 2 and 2.Its thrust reach 60 tons～460 tons adjustable.
