Embodiment Construction

[0015] A hoisting structure for an oil-immersed distribution transformer oil tank, see Figure 4 with Figure 5 , the lifting structure includes lifting lugs 1, the lifting lugs are processed by two angle steels 3 located on both sides of the fuel tank along the edge 2, and the lifting lugs are located at the ends of the two angle steels. The lifting lug is made by punching out two angle steels at the end with a punching machine at one time. The two angle steels positioned on both lateral sides of the fuel tank protrude from the fuel tank body, and the lifting lugs are arranged at the position protruding from the fuel tank body 4 outside. The lifting lug includes a lifting lug hole and a notch. The lifting lug along the box is an integral structure.

[0016] Practice has proved that the structure is simple and easy to implement, and fully guarantees the reliability of the oil tank lifting and meets the production requirements. At the same time, this structure saves a lot o...

Abstract

The invention discloses a lifting structure for an oil immersion type distribution transformer oil tank. The structure comprises lifting lugs manufactured from two pieces of angle iron on the two sides of the edge of the oil tank and located at the ends of the two pieces of angle iron, and the lifting lugs are formed through one-time punching of the ends of the two pieces of angle iron by means of a punch. According to the lifting structure, lifting lugs adopted in a traditional structure are omitted, manufacturing procedures are simple, and materials are saved; process cycle is short, and large-scale and bulk production is facilitated.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing and relates to a lifting structure for an oil tank of an oil-immersed distribution transformer. Background technique [0002] The lifting structure of the traditional oil-immersed distribution transformer oil tank is as follows: Figure 1 to Figure 3 shown. The tank edge 12 of the fuel tank 11 is assembled and welded by four angle steels 14, and the lug 13 used as lifting the fuel tank shell is a separate part, which is processed through blanking, turning, cutting, grinding and other processes. After the main body of the fuel tank is welded, the lifting lugs are welded to the lower opening of the angle steel along the tank and the four corners according to the marks in the drawing. This structure has been used for many years, but its disadvantages are: complex processing procedures and waste of materials; long processing cycle, which is not conducive to large-scale and batch production. ...
