It is flexible, it is also possible to fracture when serious, and the toughness of longer spring is not also strong, is unfavorable for the long-time service of damping device.
The content of the invention
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of dry-type transformer damping device.
The technical issues of the utility model, is mainly addressed by following technical proposals：
A kind of dry-type transformer damping device, including upper backup pad, lower supporting plate, big sleeve, middle sleeve, small sleeve, in
Stem and spring, wherein middle sleeve are fixed on lower supporting plate middle vertically, and the newel, big sleeve and small sleeve top are equal
Upper backup pad bottom middle is fixed on vertically, the bottom of wherein newel and small sleeve is respectively positioned in big sleeve, outside big sleeve
Be sleeved on middle sleeve, it is also outer up and down on the newel to be cased with two groups of springs, the newel between two groups of springs be equipped with will in
The position-limit mechanism that sleeve is halved in height, the position-limit mechanism include the two pieces of circular baffle plates overlapped up and down, middle position
It is fixedly connected in the baffle edge of top with middle sleeve madial wall, underlying baffle is fixed on newel.
Preferably, underlying spring bottom end is locked at by bolt on lower supporting plate in the spring.
Preferably, the newel is placed through the baffle center of circle of top, and newel length is not more than middle sleeve height.
Preferably, four vertex of the upper backup pad and lower supporting plate are equipped with mounting hole.
Preferably, it is coaxially disposed between the big sleeve, middle sleeve, small sleeve and newel.
Preferably, the small sleeve housing is on the spring being located above, and the height of small sleeve is not more than big sleeve top
Spacing between end and position-limit mechanism.
The beneficial effects of the utility model are：Transformer damping device provided by the utility model can efficiently solve change
Vibration when depressor is run is transferred, and the gun iron link of transformer and foundation base is made to change into elastic connection, has effectively cut off and has shaken
Moving noise route of transmission, the construct noise that barrier is propagated by solid, because the buffering effect that long spring is provided is stronger, but it is long
Spring is being easily bent under the influence of by larger vibroseis, is also possible to fracture when serious, and the toughness of longer spring is not also strong
The reason for, the utility model ensure that the entirety of spring by the way that previous Single spring to be made into present double short spring modes
During length, also so that spring is unlikely to deform, while the service life of spring is also extended.
