Description
Technical Field
The invention relates to a welding structure and a welding method of a transformer box edge, and belongs to the technical field of transformers.
Background
The transformer tank is extremely complicated along the welded traditional structure and is difficult to operate. The traditional structural box edge welding method is that a box cover and a box edge are positioned by hook-shaped fixing plates, the upper and lower hook-shaped fixing plates are assembled together in a meshed mode and then welded, the fixing plates are respectively welded on the box cover and the box edge, and finally the box cover and the box edge are welded into a whole, as shown in fig. 1 and 2. The method needs to manufacture a plurality of hook-shaped fixing plates with complex shapes, and the operation of welding the hook-shaped fixing plates on the box edge is difficult, so that the workload is high; finally, when the box cover and the box edge are welded together, the box edge at the shielding position of the fixing plate needs to be drawn from the side face for welding, and the operation difficulty is high. Although the box edge welded structure can effectively solve the problem of local overheating of the box edge, the traditional box edge welded structure is not widely popularized and used because the welding structure is complex, the welding difficulty is high, and the welding period is long.
Disclosure of Invention
The invention aims to provide a welded structure and a welded method of a transformer tank edge, which change the positioning mode of the welded structure of the tank edge, greatly simplify the welded structure of the tank edge, simplify the welding operation, greatly improve the efficiency and solve the problems in the background technology.
The technical scheme of the invention is as follows:
the utility model provides a transformer tank edge welds dead structure, contains case lid, case edge, location square steel and sealing washer, and the case lid lower surface is equipped with location square steel, and case edge upper surface is equipped with rectangle recess one and rectangle recess two, and location square steel and sealing washer match with rectangle recess one and rectangle recess two respectively, and location square steel and sealing washer set up respectively in rectangle recess one and rectangle recess two, and case lid and case edge outside welding.
The depth of the first rectangular groove is larger than that of the second rectangular groove.
The first rectangular groove is arranged on the inner side of the second rectangular groove.
A method for welding a transformer tank edge adopts the welding structure, and comprises the following steps: and welding positioning square steel on the lower surface of the box cover, processing a first rectangular groove and a second rectangular groove on the upper surface of the box edge, placing the positioning square steel in the first rectangular groove, placing a sealing gasket in the second rectangular groove, and finally welding the box cover and the box edge together.
The beneficial effects of the invention are as follows: the structure is simple, the positioning effect is obvious, only the box cover and the box edge are required to be welded together, the welding position is good, the operation is good, the welding workload is small, and the welding quality is easy to ensure.

FIG. 2 is a schematic view of the A-direction of FIG. 1;
FIG. 3 is a schematic diagram of the structure of the present invention;
in the figure: the box cover 1, the box edge 2, the positioning square steel 3 and the sealing gasket 4.
Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings.
The utility model provides a transformer tank edge welds dead structure, contains case lid 1, case edge 2, location square steel 3 and sealing washer 4, and case lid 1 lower surface is equipped with location square steel 3, and case edge 2 upper surface is equipped with rectangle recess one and rectangle recess two, and location square steel 3 and sealing washer 4 match with rectangle recess one and rectangle recess two respectively, and location square steel 3 and sealing washer 4 set up respectively in rectangle recess one and rectangle recess two, and case lid 1 and case edge 2 outside welding.
The depth of the first rectangular groove is larger than that of the second rectangular groove.
The first rectangular groove is arranged on the inner side of the second rectangular groove.
A method for welding a transformer tank edge adopts the welding structure, and comprises the following steps: the lower surface of the box cover 1 is welded with a positioning square steel 3, a rectangular groove I and a rectangular groove II are processed on the upper surface of the box edge 2, the positioning square steel 3 is placed in the rectangular groove I, the sealing gasket 4 is placed in the rectangular groove II, and finally the box cover 1 and the box edge 2 are welded together.
The invention breaks the traditional positioning mode, changes to positioning without a fixed plate, and considers positioning by the box along itself; the box edge positioning and welding method is changed by changing the structure of the box edge, and the box edge welding method is fundamentally changed by the reverse thinking method.
The box edge structure batch production can be used for drawing the finished steel products, the structure is simple, the positioning effect is obvious, the original complex hook-shaped fixed plate structure is replaced, and the welding workload is avoided. The whole tank edge welded structure only needs to be welded with the tank cover and the tank edge together, the welding position is good, the operation is good, the welding workload is small, the welding quality is easy to ensure, and the strength of the tank edge welded structure oil tank meets the use requirement through three-dimensional simulation calculation contrast.
The tank edge welding structure can be suitable for barrel-type and bell-type oil tanks, the difficulty of tank edge welding can be effectively reduced, the efficiency of tank edge welding can be improved, and the tank edge welding structure can effectively solve the problem that the popularization of the tank edge overheated structure can be greatly enhanced.
