Abstract

The utility model discloses a new main body hanger of an upper oil-saving tank, which comprises a hanger round steel, reinforcing plates I and II and a U-shaped reinforcing iron, wherein the reinforcing plate I and the hanger round steel are welded into an integral body at the inner plane of the U-shaped reinforcing iron, the reinforcing plate II is inserted into the hanger round steel and is welded with two flanks of the U-shaped reinforcing iron, and the U-shaped reinforcing iron is integrally tiled and welded on the wall of a tank. In the utility model, the reinforcing plate is changed from the external weld into built-in weld, and the hanger round steel and the reinforcing plate are not welded together with the wall of the tank. The utility model solves the problems that since the round steel of the main body hanger and the reinforcing plate are entirely welded on the plane of the tank wall, the existing main body hanger has thick reinforcing plate, large welding current and thin tank wall unevenly heated, which causes the tank wall to generate the welding deformation that brings lots of difficulties for magnetic shield assembly and clamping plate weld, and the weld seam of the U-shaped reinforcing iron and the tank wall splits. The utility model simplifies the welding process of the main body hanger, the integral appearance of a transformer is improved, the steel cable operation is convenient when the main body is lifted, and the utility model either reduces the labor intensity or creates certain economic benefit.

Description

A kind of novel main body that goes up the fuel-economizing case is hung and is mixed

Technical field

The utility model relates to fuel-economizing box part technical field of structures on the transformer, is applicable to particularly that the novel main body of fuel-economizing case is hung on the above and 220kV transformer of 110kV capacity 90000KVA to mix.

Background technology

Development along with the national grid construction, company's big capacity voltage levels transformer is ordered goods more and more, low-loss, high-performance variable depressor extremely user's letter are looked at, for reducing stray loss, the magnetic screen measure has all been taked in big capacity voltage levels oil tank of transformer inside, and the welding of magnetic screen clamp and magnetic screen assembling require very high to the flatness of tank wall.Yet, existing main body hangs that hanging of mixing mixed the round steel stiffener and round steel weldering earlier is one, this integrated member lies on the tank wall plane again and welds with tank wall, upright U type is strengthened iron tiling tank wall to be made to hang and mixes round steel and stretch out the U type and strengthen iron, and another stiffener shop is welded in the U type and strengthens the iron outer surface and hang that to mix that round steel welds firmly be an integral body.The problem that such structure exists is: 1, hang because of main body and mix round steel and be welded in the tank wall plane with stiffener integral body jail, owing to strengthen thickness of slab, welding current is big, and the thin and inequality of being heated of tank wall makes tank wall produce welding deformation and brought many difficulties to magnetic screen assembling and clamp welding; 2, hang because of main body and mix round steel and stiffener is welded in tank wall, another stiffener is welded in the U type outward and strengthens iron surface, main body lifting force F when lifting is subjected to this structural constraint F power easily to be dispersed to tank wall generation reaction force F ' and causes the U type that uprightly is welded on the tank wall to strengthen iron and tank wall bond open vertically upward; 3, the welding manner of this version has brought very big restriction to the requirement of tank wall flatness.

Summary of the invention

Goal of the invention of the present utility model is to solve above-mentionedly mixes round steel and stiffener integral body and puts and be welded in tank wall because of hanging, because welding current is big, tank wall is thin, thereby make tank wall produce welding deformation, welding has brought weak point to magnetic screen assembling and clamp, and provide a kind of and manufacture that process is simple, intensity reliably, the novel main body that can avoid welding, lift by crane the last fuel-economizing case of distortion hangs and mixes.

The technical scheme that the utility model adopted is: a kind of novel main body that goes up the fuel-economizing case is hung and is mixed, comprise hanging and mix round steel, stiffener I, II, U type reinforcement iron, it is characterized in that stiffener I mixes round steel to strengthen the weldering of iron inner plane in the U type be an integral body with hanging, stiffener II penetrates to hang and mixes round steel and the two sides welding of U type reinforcement iron, and the U type is strengthened the whole tiling of iron and is welded in tank wall.

The utility model changes stiffener into built-in weldering by external, hangs to mix round steel and stiffener is not welded together with tank wall.Owing to adopted above design, the utility model has solved existing main body and has hung the problem of mixing existence: 1, hang because of main body and mix the whole jail of round steel and stiffener and be welded in the tank wall plane, owing to strengthen thickness of slab, welding current is big, and the thin and inequality of being heated of tank wall makes tank wall produce welding deformation and brought many difficulties to magnetic screen assembling and clamp welding; 2, hang because of main body and mix round steel and stiffener is welded in tank wall, another stiffener is welded in the U type outward and strengthens iron surface, main body lifting force F when lifting is subjected to this structural constraint F power easily to be dispersed to tank wall and produces U type reinforcement iron and the tank wall bond open that reaction force F ' causes upright weldering vertically upward.The utility model has been simplified main body and has been hung and mix welding process, hangs to mix round steel, stiffener and be welded in the U type and strengthen iron inside and become a whole back tiling and be welded in tank wall and get final product; Stiffener is put weldering U type and is strengthened no longer having multilayer weld behind the iron inside, makes that the transformer bulk shape is attractive in appearance to be improved, during main body lifting simultaneously the steel wire rope operation also very convenient, not only reduced labour intensity but also created certain economic benefits.
