Abstract
A boiler membrane type wall edge flat steel welding tooling consists of auxiliary flat steel and an auxiliary tube. The outer diameter of the auxiliary tube is equal to outer diameters of tubes of a boiler membrane type wall tube panel, the auxiliary flat steel is welded onto the outer side wall of the auxiliary tube and is welded along the radial direction of the auxiliary tube, and the width of the auxiliary flat steel is equal to the pitch between each two tubes of the boiler membrane type wall tube panel. The boiler membrane type wall edge flat steel welding tooling adopts the auxiliary tube and the auxiliary flat steel, the diameter of the auxiliary tube is equal to the diameters of the tubes in the tube panel, the width of the auxiliary flat steel is equal to the pitch between each two tubes in the tube panel, end sleeves are clamped by two ends of a welder when the tube panel is welded, so that the tooling and a tube bank to be welded form the tube panel while the auxiliary flat steel is not welded with welding joints among flat steel edges of the tube panel, then the tube panel is welded, and the tooling is taken down to be used for welding a next tube panel.
Description
Technical field
The utility model relates to mechanical field, and particularly boiler specifically is a kind of boiler membrane wall edge band steel welding tooling.
Background technology
The burner hearth of internal circulating fluidized-bed boiler all is by the three fin panel casing heating surfaces in left, center, right, the burner hearth of external circulation fluidized bed is made up of front-back wall, left and right sides wall membrane wall, the boiler that big steam power plant uses, except that burner hearth, how its bag wall superheater, reheater also are made up of tube panel.And the burner hearth of chain furnace, coal-powder boiler, oily vapour stove in recent years, for increasing sealing effectiveness, also much adopted the film mode tube screen structure, tube panel is to add the band steel butt welding by pipe to form, general tube panel is by MPM(Mitshbishi panel Processing Machine) welding machine and submerged arc welding machine be welded, when building-site is installed with the water-cooled tube panel butt welding of same face wall together, integral hoisting, traditional technology is after membrane wall is welded into, the cut edge band steel.Be subjected to the restriction of MPM welding machine mould, when the welded pipe group, the edge band steel needs unanimity with band steel width dimensions in the tube panel, the unnecessary band steel of welding back excision, and the band steel that scales off is difficult to utilize owing to the restriction of width again, this is equivalent to waste the edge band steel of half, by 30 of the tube panels that need cut edge band steel is arranged in every boiler, the length of every screen has been wasted about 250 kilograms band steel by 10 meters calculations.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler membrane wall edge band steel welding tooling, described this processing tool will solve the waste that needs the margins of excision band steel when making the boiler tube panel in the prior art and cause band steel, increases boiler cost techniques problem.
The purpose of this utility model is achieved through the following technical solutions: it is made of auxiliary band steel and auxiliary pipe, the external diameter of auxiliary pipe equates with the tube outer diameter of boiler membrane wall tube panel, auxiliary band steel is welded in auxiliary pipe lateral wall, auxiliary band steel is along auxiliary pipe radial direction welding, and the width of auxiliary band steel equates with the pitch of the pipe of boiler membrane wall tube panel.
The thickness of auxiliary band steel is identical with tube panel band steel thickness.
Boiler membrane wall tube panel band steel width is between 8 mm～120mm.
Auxiliary pipe both sides all are welded with band steel, and both sides band steel thickness is that 3～16mm, width are in 4～120mm scope.
Assistant edge band steel material is a steel plate.
Auxiliary tube outer diameter is that pipe thickness is between 3～16mm between φ 25～φ 89mm.
The length of this boiler membrane wall edge band steel welding tooling is more than or equal to tube panel length.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model adopts auxiliary pipe and the auxiliary band steel that equates with pipe diameter in the tube panel in boiler membrane wall edge band steel welding tooling, auxiliary band steel and width equate with pipe pitch in the tube panel, therefore when the welding tube panel, pass through the two ends pinching end cover of welding machine, make this frock and the pipe group that will weld form a tube panel, but weld seam does not weld between auxiliary band steel and tube panel edge band steel, the welding of a slice tube panel is finished, and this frock is taken off, and is used for the welding of a slice tube panel down.
Description of drawings
Fig. 1 is the utility model boiler membrane wall edge band steel welding tooling structural representation.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, in the present embodiment, this welding tooling is made of auxiliary band steel 1 and auxiliary pipe 2, the external diameter of auxiliary pipe 2 equates with pipe 3 external diameters of boiler membrane wall tube panel, auxiliary band steel 1 is welded in auxiliary pipe 2 lateral walls, auxiliary band steel is along auxiliary pipe radial direction welding, and the width of auxiliary band steel 1 equates that with the pitch of the pipe of boiler membrane wall tube panel the thickness of auxiliary band steel 1 is 6mm.
During concrete the use,, make this frock and the pipe group that will weld form a tube panel by the two ends pinching end cover of welding machine, but weld seam does not weld between auxiliary band steel and tube panel edge band steel, the welding of a slice tube panel is finished, and this frock is taken off, and is used for the welding of a slice tube panel down.
Specification difference according to the boiler membrane wall, can adopt the auxiliary band steel and the auxiliary pipe of different size, both sides band steel thickness can be 3～16mm, width in 4～120mm scope, and auxiliary tube outer diameter is between φ 25～φ 89, and pipe thickness is between 3～16mm.
