Large power transformer oil tank welding flip frame

Abstract

The invention relates to a large-scale power transformer oil tank welding flip frame, which belongs to the technical field of special tooling for transformers. The technical scheme includes a frame body (1), a base (6), an adjustable length support shaft, an adjustment shaft (8), and an adjustment screw (9). The middle of the frame body is hinged on the base, and the two ends of the frame body are respectively provided There is an adjustable length support shaft connected to the base, and an adjustment shaft and an adjustment screw are also arranged between the frame body and the base; the rotating motion of the adjustment screw is converted into the angle required by the working surface of the frame body, and the fixed If the angle is required, place the fuel tank on the working surface of the frame body and perform welding on the flat welding position. The invention can create favorable working conditions for the oil tank to be overturned for flat welding, solve the disadvantage of crane auxiliary welding, greatly reduce the occupation of lifting equipment, and better relieve the tension of crane turnover at the production site.

Description

[0001] Technical field: [0002] The invention relates to a large-scale power transformer oil tank welding overturning frame, which belongs to the technical field of special tooling for transformers. Background technique: [0003] The large transformer oil tank is not only a container for the body of the oil-immersed transformer and high-quality transformer oil, but also withstands various mechanical forces during the lifting and transportation of the transformer. The weld seam quality of the oil tank is very important, which not only affects the mechanical strength of the oil tank, but also affects the major problem of transformer oil leakage. The transformer oil tank is mainly composed of an upper fuel tank and a lower fuel tank. The fuel tank assembly process: usually, the lower fuel tank is welded first, and then the upper fuel tank is assembled. After all parts outside the fuel tank are spot-welded, disassemble the upper and lower fuel tanks, put the upper and lower f...

AI Technical Summary

Problems solved by technology

As we all know, the welding quality of the flat seam is the best. Because of the relatively large size of the fuel tank, it is very troublesome to adjust the welding seam position. The background technology is to weld in a horizontal position with a crane, which is unsafe and occupies the crane. and less productive
