Abstract
The utility model discloses a edge sheath of transformer oil tank, which comprises a tank body, a plurality of joint hinges and a tank cover, wherein, a bulgy tank edge is arranged around the top of tank body, an edge retracted up and down, projected in the middle is arranged between the tank edge and tank cover above each joint hinge, the sheath is a transverse U shape inserter with opening on a side, closed on the other side, which can cover the tank cover and tank edge. Since the utility model adopts the technical proposal, the utility model can solve the problem of wire rope pulling off the paint on tank edge during hoisting of transformer oil tank by means of just adding a simple structure, low cost sheath on tank edge at the joint hinge of each transformer oil tank, without changing original joint hinge dimension on the transformer oil tank.
Description
Technical field
The utility model relates to the accessory of oil tank of transformer, and the case that is specifically related to a kind of oil tank of transformer is along sheath.
Technical background
Be equipped with joint hinge on the existing oil tank of transformer, be convenient to when installing or paint, often will lift by crane, yet steel wire rope can pull off the paint on the case edge when fuel tank lifts by crane,, this position corrosion is damaged so this position gets rusty easily most.The existing method that solves is that the size of the joint hinge of fuel tank is extended, steel wire rope is not run into the case edge when making lifting, but this method but makes the stress condition variation of joint hinge, because the joint hinge size lengthens, joint hinge upwards turns over and causes that tank wall distortion, joint hinge weld paint problems such as explosion when lifting, for head it off, must between joint hinge and fuel tank tank wall, weld a stiffener, though the stress condition of joint hinge has improved, but the easy ponding of this weld gets rusty and cost increases, and how head it off does not have good plan all the time.
Summary of the invention
So the utility model purpose is overcoming the deficiencies in the prior art, the case that a kind of oil tank of transformer is provided is along sheath, and it can not pull off the paint on the case edge because of steel wire rope when fuel tank lifts by crane under the situation that does not change original joint hinge size.
The technical scheme that realizes above-mentioned purpose is: a kind of case of oil tank of transformer is along sheath, comprise casing, some joint hinges and case lid, have the case edge of protrusion around this casing top and between case edge above each joint hinge and case lid, form indentation up and down, middle outstanding edge, this sheath is the horizontal U-shaped shape plug-in unit of a side opening, opposite side sealing, and can coat the edge on described case lid and case edge.
The case of above-mentioned oil tank of transformer is along sheath, wherein, the closed side of described sheath be up-small and down-big stairstepping portion so that the bottom of its closed side can with the edge coupling on described case lid and case edge.
The case of above-mentioned oil tank of transformer is along sheath, and wherein, the open height of described sheath equals the thickness sum of the thickness and the case lid on described case edge.
The case of above-mentioned oil tank of transformer is along sheath, and wherein, the height of going up stairstepping portion in the described sheath is the thickness of case lid, and the height of downstairs shape portion is the thickness on case edge in the described sheath.
The case of above-mentioned oil tank of transformer is along sheath, and wherein, described sheath width is greater than the thickness of joint hinge.
Owing to adopted the technical scheme of the case of oil tank of transformer of the present utility model along sheath, promptly only on the case edge at each oil tank of transformer joint hinge place, add and overlap a sheath simple in structure, with low cost, just can under the situation that does not change original joint hinge size on the oil tank of transformer, solve the oil tank of transformer problem that steel wire rope can pull off the paint on the case edge when lifting.

Fig. 1 is the user mode schematic diagram of the case of oil tank of transformer of the present utility model along sheath;
Fig. 2 is a kind of example structure schematic diagram of the case of oil tank of transformer of the present utility model along sheath;
Fig. 3 is that the case of oil tank of transformer of the present utility model is along the another kind of example structure schematic diagram of sheath.
Embodiment
See also Fig. 1 to Fig. 3, the case of a kind of oil tank of transformer of the present utility model is along sheath, comprise casing 1, some joint hinges 2, case lid 3 and sheath 4, the case that has protrusion around this casing 1 top along 10 and the case above each joint hinge 2 along 10 and case lid 3 between form indentation up and down, middle outstanding edge, sheath 4 is the horizontal U-shaped shape plug-in unit of a side 41 openings, opposite side 40 sealings, and can coat described case lid 3 and the case edge along 10, the open height L of this sheath 4 equal case along 10 thickness and the thickness sum of case lid 3.
In one embodiment, the closed side 40 of sheath 4 be up-small and down-big stairstepping portion so that the bottom of its closed side 40 can with case lid 3 and the case edge coupling along 10, the height L1 that go up stairstepping portions in the sheath 4 are the thickness of case lid 3, and the height L2 of downstairs shape portions is a case along 10 thickness in the sheath 4.
The width of above-mentioned two kinds of sheaths is greater than the thickness of joint hinge 2.
Because after having adopted above-mentioned connection technology scheme, make oil tank of transformer when lifting, as long as with the case of a kind of oil tank of transformer of the present utility model along sheath be enclosed within each joint hinge 2 top by case lid and case along the edge that forms, just can stop steel wire rope can pull off case along last paint phenomenon fully.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (5)
1. the case of an oil tank of transformer is along sheath, comprise casing, some joint hinges and case lid, have the case edge of protrusion around this casing top and between case edge above each joint hinge and case lid, form indentation up and down, middle outstanding edge, it is characterized in that, this sheath is the horizontal U-shaped shape plug-in unit of a side opening, opposite side sealing, and it can coat the edge on described case lid and case edge.
