After U-shaped board no longer moves down, the first spring and telescopic rod are no longer compressed, the first rack gear and the second rack gear far from top plate one
End is not in contact with bottom plate, and the upper end of lower U-shaped board 4 is not contacted with the bottom of transformer cabinet body；Four buffer gears 5 are through upper U
Template shares the weight of transformer cabinet body；Since two base mechanisms be pre-adjusted, ground is placed in transformer
Afterwards, the bottom of transformer cabinet body is parallel to the ground, and transformer is in leveling state；When transformer lifting is placed on the process on ground
In, when lifting deviates and transformer is made to be placed on the excessive velocities on ground, pass through telescopic rod in buffer gear and first
The reciprocating compression of spring reaches and transformer interior of the cabinet is avoided to be impacted come impact force generated when absorbing transformer placement
The purpose of damage；After transformer test, when transformer carries out factory transport and lifting installation, transformer needs to take out one
Part oil, prevents the leakage for occurring oil in transportational process；After transformer takes out a part of oil, the self weight of transformer cabinet body subtracts
Small, under the reset response of the first spring, the first spring and telescopic rod restore certain decrement, new to adapt to transformer cabinet body
Self weight；When transformer needs lifting to be mounted on ground or transformer bracket, transformer is placed on ground by steady lifting
Or on transformer bracket；During transformer is placed in lifting, lifting deviates and makes the excessive velocities of transformer placement
When, generated impact force when transformer is placed is absorbed by the reciprocating compression of telescopic rod in buffer gear and the first spring,
Achieve the purpose that avoid transformer interior of the cabinet by impact damage；When transformer is lifted and is placed, on lower U-shaped board and ground or
After the contact of person's transformer bracket, the lifting that continues of transformer cabinet body places and U-shaped board can be made to move down；Upper U-shaped board is to moving down
When the moving down speed difference of both ends of the upper U-shaped board of appearance during dynamic, the first rack gear and the second rack gear move down speed not
Together, synchronization mechanism movement enables the first rack gear and the second rack gear to move down synchronization quickly when, the both ends of U-shaped board in guarantee
Energy horizontality steadily moves down, to guarantee that the structure in base mechanism is in horizontality, and horizontality lower bottom base
Structure stress in mechanism can be uniformly；After transformer lifting of the invention is placed on ground or transformer bracket,
The compression of the first spring and telescopic rod in buffer gear reaches steadily, at this time the first rack gear and the second rack gear far from top plate one
End is not in contact with bottom plate, and the upper end of lower U-shaped board is not contacted with the bottom of transformer cabinet body 1；Four buffer gears 5 pass through at this time
Upper U-shaped board carries out load-bearing to transformer cabinet body；Next, in order to enable the good long-time of base mechanism 2 to transformer
Cabinet body support, avoids four buffer gears from possible failure conditions, pedestal occur when carrying out load-bearing to transformer cabinet body for a long time
Mechanism is equipped with bearing block and voussoir；For any one base mechanism: two bearing blocks are inserted respectively into lower U by construction personnel
The both ends of template, until two bearing blocks are inserted by the center that two baffles block and can not continue U-shaped board down, at this time two
A bearing block has been positioned between lower U-shaped board and upper U-shaped board, and there are small between the top plate 1 of upper U-shaped board for two bearing blocks
Gap；Then, two voussoirs are tightly squeezed respectively and is inserted into two small―gap sutures between bearing block and top plate, two such
Bearing block can share the substantial portion of load-bearing of transformer cabinet body, reduce the load-bearing of four buffer gears, reach protection four
The effect of buffer gear；After bearing block and voussoir in base mechanism are all complete, construction personnel is by the oil in transformer
Amount is filled up to the amount of transformer normal use again；For setting for third rack gear, the 4th gear, the 4th shaft and positive hexagonal ring
Meter, worker only need to adjust positive hexagonal ring, can make third rack movement, so that four buffer gears can be adjusted in synchronism,
Reach and reduce the workload that worker is adjusted, improves work task efficiency；For bearing block and voussoir: dispatching from the factory and carry in transformer
Before take out a part of oil after, the spacing between top plate and bottom plate determines the specification of bearing block and voussoir, can be according to oil pumping amount
To be produced in batches to bearing block and voussoir.
