Multifunctional header assembly frame

Abstract

The invention relates to a multifunctional header assembly frame, which is suitable for assembling a plurality of long tube joints with a header body in a boiler header. The header body to be assembled is arranged on lining shape steel, such as H-shaped steel; the header body is fixed onto the H-shaped steel through a plurality of handcuff plates comprising header pressing plates and staggered pressing plates to ensure the straightness when the header body is assembled; the length direction of the header is provided with a plurality of peripheral frames with adjustable dimensions and positions at intervals; and the matched long tube joints are fixedly supported in the assembly process of the header. In the multifunctional header assembly frame, a plurality of channel steel and flat steel among banks of tubes are also respectively fixed in place when assembly welding is performed to support the banks of tubes, thereby, the assembly precision of the long tube joints is ensured. The multifunctional header assembly frame can be suitable for assembling the long tube joints with different structures with the header, is capable of preventing the header from deforming in the processes of welding and heat treatment, and is capable of conveniently performing hoisting and swinging, the turnover and the hydrostatic test on the header and subsequent allowance processing on the long tube joints.

Description

technical field [0001] The invention particularly relates to a multifunctional header assembly frame, which is a tool for assembling boiler headers. Background technique [0002] Such as figure 1 Shown is an existing water-cooled wall intermediate transition header in a 600MW class W flame supercritical boiler, which includes a header body 19 and a number of long pipe joints 18 correspondingly connected to a number of pipe holes on the header body 19 . Because the frame structure formed by these long pipe joints 18 is very special, and the closed frame space size is large, the distance between adjacent pipes is close, and the center of gravity of the frame is biased; The assembly and welding of the box body can be completed by the roller frame, but the roller frame cannot be used for the assembly and manufacture of the special frame-shaped long pipe joint and the header body, which brings inconvenience to the entire production process of the header.
