Specific embodiment
Below with reference to embodiment, the present invention will be further described, and it is not limited that following embodiments, which are illustrative,
, the protection scope of the utility model cannot be limited with following embodiments.
A kind of transformer double-layer shock-absorbing device, as shown in Figure 1,2,3, 4, the innovation of the utility model is: including pedestal 4
With installing frame 11, pedestal interval is arranged and multiple installing frames are horizontally installed between two pedestals, above installing frame upper surface
Mounting plate 9 is set, which is arranged with installing frame upper end face interval and is vertically arranged in bottom surface and installing frame multiple
Spring 10 connects.
In the present embodiment, installing frame and matched mounting plate are three, and installing frame is hollow structure and upper end is opened
Mouthful.The vertical section 12 of installing frame both ends setting one, the bending section 17 of each vertical section outside setting one, the bottom of the bending section
Face is connect with pedestal, and installation board ends have the vertical portion 8 for being pressed in vertical section inside opening and the bending above bending section
Portion 6, bending part bottom surface are connect with the spring 7 being arranged in vertical section.Bottom surface and installing frame middle part upper surface retain in the middle part of mounting plate
Gap 3, the interior multiple springs being arranged in installing frame middle part, each lower spring end are connect with the fixing seat 14 of installing frame inner bottom surface, bullet
The upper end of spring is stretched out outside installing frame, and when transformer is connect with mounting plate, mounting plate bottom surface can retain with installing frame upper surface
The gap of one very little absorbs the vibration that transformer generates from there through compressed spring.Likewise, bending part bottom surface and folding
Curved segment upper surface also retains certain interval, and spring is also equipped at this for absorbing the vibration of transformer.
Between the middle part of an installing frame and mounting plate substantially shape being recessed in detail, installing frame middle part bottom surface and ground retain
Gap 13, the gap are 30 millimeters or so, preferably 30 millimeters, in this way reduce the position of centre of gravity of transformer, since vertical portion is pressed
At vertical section inside opening, then with after the cooperation of multiple springs, avoid the double swerve problem generated by transformer vibration.
Multiple pressure springs 19 are arranged in pedestal, a pressure spring is arranged in each protrusion for the protrusion 5 of pedestal both ends setting one
15,1 bottom surface of pressing plate that each pressure spring extend out to the upper end of chassis outer side and one and base shape match is connect, in the middle part of pressing plate
The bottom surface of the upper surface connection bending section of recess 18.
Pedestal and protrusion are similarly hollow, the middle of the base upper end opening, the inside opening of high spot.In the middle part of pressing plate downwards
It is recessed and retains certain interval 3 with the middle of the base upper surface, prolongs portion 16 on pressing plate both ends and be pressed in raised inside opening, above prolong portion
The bending part 2 of upper end and raised upper end retain certain interval.Multiple fixing seats, each fixing seat connection one is arranged in pedestal inner bottom surface
The lower end of a pressure spring, the upper end of each pressure spring 15,16 stretch out pedestal and protrusion it is outer and respectively with bottom surface in the middle part of pressing plate and bending part
Bottom surface connection, by the compression of pressure spring and on prolong portion and avoid transformer because shaking swaying forwards and backwards for generation with the contact of protrusion
Problem.
As shown in figure 4, bending section bottom surface 20 is fixed by bolt 24 and pressing plate 18, which is located at the outer rim above pressing plate
Outer rim between (between nuts 23 and bending part bottom surface) and bending section bottom surface and pressing plate upper surface is set with rubber pad
22、21。
Pedestal is fixed on ground, and bolt is coated in pedestal or is coated with spiral shell in the fixinig plate of pedestal lower end setting
Bolt, the outer rim which is located above pedestal or fixinig plate are set with rubber pad, which is located at base end face or fixinig plate bottom
Outer rim between face and ground is set with rubber pad.
It in the utility model, is bonded together on mounting plate by soft medium and transformer bottom surface, mounting plate passes through more
A spring is connect with installing frame, thus forms first shock-damping structure, and installing frame both ends are pressed in the pressing plate being arranged on pedestal
On, pressing plate passes through multiple pressure springs again and connect with pedestal, thus forms second shock-damping structure, can by two shock-damping structures
It is effective absorb or alleviate transformer because the generations such as iron core, winding vibration, bearing's setting two of installing frame and pressing plate
The junction on rubber pad, pedestal and ground is arranged two rubber pads and further reduced shake by the combination of these rubber pads
Dynamic, the recess among installing frame reduces the height of C.G. of transformer entirety, various structures mutual cooperations, realize well every
Effect is shaken, solves the problems, such as transformer shaking.
