Detailed ways

All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

As shown in Figure 1, an oil-immersed power transformer includes a rubber base 1, on which a metal oil tank 2 and an oil conservator 3 are installed, a transformer body 4 is installed in the oil tank, and a rubber base is provided in the center of the top. Through hole, the design of the through hole is relatively large, so that the bottom of the fuel tank can be completely inserted into the through hole.

In this embodiment, the through hole runs through the rubber base from top to bottom, and the rubber base is provided with more than one connecting hole, one end of the connecting hole passes through the rubber base, and the other end of the connecting hole is connected to the through hole 5; Above the support plate 6, the side of the support plate is connected with more than one shock-absorbing compression spring 7, and the shock-absorbing compression spring passes through the connecting hole to connect a fixed plate 8; a shock-absorbing rubber block 9 is passed between adjacent two support plates connect.

Among them, the supporting plate, the shock-absorbing compression spring, and the fixing plate are all made of high-strength stainless steel, with an integrated structure and high strength. The top supporting plate is welded and fixed to the fuel tank.

Wherein, the fixing plate has a disc structure, and the diameter of the fixing plate is 1 cm to 3 cm longer than the diameter of the connecting hole.

Wherein, the shock-absorbing rubber block is bonded to the support plate.

Working principle: The top support plate is welded and fixed to the fuel tank, because the fuel tank makes gravity downward, which makes the support plate downward and stretches the shock-absorbing compression spring, so that the corresponding fixed plate is closely attached to the rubber base, making the entire structure stable Strong, the pressure generated by the fuel tank all acts on the support plate, and the shock-absorbing rubber blocks between the support plates increase the shock resistance and compression resistance. The connecting holes can be designed from top to bottom, and multiple connecting holes are designed at the same height, and the shock-absorbing compression springs on the support plate pass through the connecting holes at the same height.

In this embodiment, the top of the rubber base is screwed to a bottom plate 10, and more than one rotating wheel 11 is mounted and fixed on the bottom of the bottom plate.

Wherein, the bottom plate is made of stainless steel.

Wherein, the side surfaces of the base are provided with threads, and the threads are arranged above the connecting holes.

The rotating wheel on the bottom plate is under less pressure and is not easy to be damaged; the position of the rotating wheel is adjusted through the thread. When placed on a plane, the rotating wheel is adjusted so that it does not touch the plane. When moving, the rotating wheel is adjusted to be in contact with the ground. Contact, the rubber base does not contact the ground; the length of the thread is designed and adjusted according to the actual situation, and the thread does not contact the fixed plate.

The beneficial effects of the utility model are: the utility model is simple in structure, easy to disassemble, and makes the whole oil-immersed transformer easy to move; when fixed, it has strong stability; it reduces the pressure on the rotating wheel, making the universal wheel have a longer service life .

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
