Abstract
The utility model relates to a clamping device for transformer or reactor. The transformer or reactor clamping device includes a clamping nail, one end of which passes through the hole on case cover and a clamping nail nut the clamping nail, the clamping nut is close against the inner wall of the case cover, a elastic element is connected between a clamping bowl and a transformer or reactor body. Structure of the utility model is simple, which can realize transformer or reactor clamping without hanging the cover, the device effectively improve working efficiency.
Description
Technical field
The utility model relates to a kind of transformer or reactor body pressing device, and the device body that is specially adapted to large-scale core type reactor compresses.
Background technology
At present, the body pressing device of domestic high-power transformer and reactor welds on folder 14 and presses oncomelania mother 13 as shown in Figure 2, presses nail 9 to follow closely on the bowl 12 by the pressure of pressing oncomelania mother 13 to act on the pressing plate, by pressing plate power is passed to the device body again.The body pressing device of this structure needs not assemble before covering fuel tank, if after transformer or reactor discovery hold down gag in service become flexible, need hang cover (removing the transformer case lid), compress its complicated operating process again, length consuming time, and restricted by field condition.And reactor is in operation because the big device body of vibration is easy to become flexible, and often will repeat this operating procedure, has wasted the valuable production time.
The utility model content
Technical problem to be solved in the utility model is at existing above-mentioned deficiency in the prior art, provide a kind of simple in structure, can realize not hanging the transformer body hold down gag that cover just can compress, effectively increase work efficiency transformer or reactor device body.
Solving the technical scheme that the utility model technical problem adopted is that this transformer or reactor body pressing device comprise that an end passes the pressure nail in case lid hole and presses the pressure nail bowl that the pressure oncomelania that nails on is female and press the nail termination, press the oncomelania mother near cover wall, press between nail bowl and transformer or the reactor device body and be crimped with flexible member.
Flexible member can adopt disk spring in the utility model.Because it is controlled that the stroke of strain takes place disk spring under external force, its stressed big I is regulated according to the disk spring modes of emplacement.Disk spring is symmetricly set in presses nail bowl two ends, and its quantity can calculate according to different transformers or the different force value of reactor product needed, and the disk spring on every limit preferably adopts 18.
Described flexible member can contact with transformer body by carriage, like this, to different transformer models, according to the difference of its device body, can adopt difform carriage to be resisted against on transformer or the reactor device body cushion block, makes the device power of experiencing even.
In order better to compress transformer or reactor device body, also can there be axle sleeve top, case lid hole, presses the nail end to stretch in this axle sleeve, and described axle sleeve inside can screw in the axle sleeve block.
When finding that in the production scene transformer or reactor device body are loosening, the utility model can compress the device body easily, reduced transformer or reactor body and annotated and drain the oil and installation time, effective simplification operation sequence, improved operating efficiency.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Following examples are indefiniteness embodiment of the present utility model.
As shown in Figure 1, the utility model comprises pressure nail 4 and presses the pressure oncomelania mother 5 who follows closely on 4 that the end of pressure nail 4 passes the case lid hole on the case lid 7, presses the inwall of oncomelania mother 5 near case lid 7, be crimped with flexible member 2 below pressing nail bowl 3, flexible member 2 contacts with the transformer body cushion block by carriage 1.In the present embodiment, flexible member 2 adopts 18 symmetrically arranged disk springs.
Be provided with axle sleeve 8 above the case lid hole, press the top of nail 4 to stretch in the axle sleeve 8, axle sleeve 8 inner screw-ins have axle sleeve block 6.
As shown in Figure 1, during assembling the utility model device body clamping device, in upper yoke oil duct in the carriage 1 bottom insertion transformer, symmetry is placed 18 disk springs on carriage 1, to press nail bowl 3 to place on the disk spring, by the aperture opened on the case lid 7 (is the case lid hole, the inside of axle sleeve 8 is dropped in the case lid hole), the technology jack 15 that is placed on axle sleeve 8 inside will be pressed down pushing of nail 4, external force is by pressing nail 4, pressing nail bowl 3, disk spring, carriage 1, device body cushion block to pass to the device body, thereby the device body is compressed.When externally applied forces reaches the required pressure of transformer body, pressing oncomelania mother 5 to be about to press oncomelania mother 5 to be threaded to cover wall by the hand hole locking of reserving on the case lid contacts, take out technology jack 15 then, in the axle sleeve 8 outside the axle sleeve block 6 screw-in case lid holes, axle sleeve block 6 is withstood press the top of nail 4 to get final product.
When the scene finds that transformer or reactor device body become flexible, axle sleeve block 6 can be screwed out from axle sleeve 8, then technology jack 15 is put into axle sleeve 8, will press down pushing of nail 4 by technology jack 15, once more the device body is compressed.When externally applied forces reaches the required pressure of transformer body, pressing oncomelania mother 5 to be about to press oncomelania mother 5 to be threaded to cover wall by the hand hole locking of reserving on the case lid contacts, take out technology afterwards very heavy 15, in the axle sleeve 8 outside the axle sleeve block 6 screw-in case lid holes, make axle sleeve block 6 withstand the top of pressing nail 4.Therefore the utility model can compress the device body easily, need not hang the cover operation, reduced transformer or reactor body and annotated and drain the oil and installation time, effective simplification operation sequence, improved operating efficiency.
