Embodiment Construction

[0021] See Figure 1 to Figure 6 As shown, a multi-pipe joint header welding device, which includes a rigid main beam 1, the two ends of the rigid main beam 1 are respectively equipped with pull plates 2, the number and position of the pull plates 2 can be adjusted according to actual needs and welding positions. Adjustment, there is a header through hole 8 on the pull plate 2, and a guide rail 9 is fixedly installed on the rigid main beam 1. The guide rail 9 is arranged between the two pull plates 2. This position can also be adjusted according to actual needs. The guide rail 9 is formed by two vertical plates 1-2 arranged side by side at intervals, reinforcing plates 1-3 are installed on both sides of the guide rail 9, movable top-tightening sliders 3 are arranged on the guide rail 9, and one side of the top-tightening slider 3 is provided with The arc-shaped tight surface that matches the surface of the header 7 is used in conjunction with headers of similar size and specif...

Abstract

The invention relates to the field of welding deformation correcting tool set-up for multi-pipe-joint header tanks and particularly relates to a welding device for a multi-pipe-joint header tank. The welding device can be used for eliminating or reducing the amount of deformation during the welding of a header tank and finned tubes so as to guarantee the welding quality of an overall finned tube panel. The welding device comprises a rigid main beam, wherein at least two draw plates are mounted on the rigid main beam, header tank through holes matched with the header tank are formed in the draw plates, the header tank penetrates through the header tank through holes, and a middle jacking device is arranged between the header tank and the rigid main beam so as to jack the rigid main beam and the header tank.

Description

technical field [0001] The invention relates to the field of multi-pipe joint header welding deformation correction tooling, in particular to a multi-pipe joint header welding device. Background technique [0002] The 9FR level horizontal waste heat furnace has more heating surface modules, and each level of heating surface modules is assembled by a modular tube panel assembled and welded by finned tubes and headers. During the assembly and welding process of finned tubes and headers at both ends, due to the large number of welded pipe joints, under the action of welding internal stress, the headers at both ends of the module tube panel are bent and deformed, which seriously affects the assembly and welding of the module tube panel Quality, which affects the assembly quality of the overall heating surface module. Contents of the invention [0003] In order to solve the above problems, the present invention provides a multi-pipe joint header welding device, which can elimi...
