Embodiment Construction
[0025] The present invention is described in detail below in conjunction with accompanying drawing:
[0026] A tooling frame for combined welding of the water-cooled wall in the transition section of a supercritical boiler, comprising a tooling frame base composed of a tooling frame base beam 1 and a tooling frame base longitudinal beam 2, and a door-shaped intermediate truss is fixedly arranged in the middle of the tooling frame base beam 1 3. An H-shaped side truss 5 is provided on the tooling base beam 1 on the right side of the door-shaped middle truss 3 , and a right tube screen insertion gap 7 is formed between the door-shaped middle truss 3 and the H-shaped side truss 5 . The right tube screen 9 is inserted into the tube screen insertion gap 7, and the right horizontal jack fixing seat 8 is fixedly arranged on the tooling frame base beam 1 between the two columns of the H-shaped side truss 5, and the right horizontal jack fixing seat 8 is connected to the H-shaped A rig...

The invention discloses a tool frame for combined welding a transition section water cooling wall of a supercritical boiler and an erecting method of the tool frame, and the technical problem of how to achieve rapid and accurate combined positioning between a pipe screen, a collecting box and a connecting pipe is solved. An H-shaped side truss (5) is arranged on a tool frame base cross beam (1) on the right side of a door-shaped middle truss (3), a right pipe screen insertion gap (7) is formed between the door-shaped middle truss (3) and the H-shaped side truss (5), a right pipe screen (9) is inserted into the right pipe screen insertion gap (7), and a right transverse jack fixing base (8) and a right transverse jack (10) are fixedly arranged on the tool frame base cross beam (1) between two stand columns of the H-shaped side truss (5); and a right collecting box support (13) and a right collecting box (17) are arranged on a right collecting box supporting beam (12), and a right connecting pipe (16) to be welded is arranged between the right collecting box (17) and the right pipe screen (9). The efficiency of the alignment process is improved.
Description
technical field [0001] The invention relates to a vertical combined platform tooling frame for a water-cooled wall in the transition section of a supercritical boiler, in particular to a vertical combined platform tooling frame for a water-cooled wall in the transition section of a supercritical boiler and an erection method thereof. Background technique [0002] In supercritical unit boilers, the water-cooled wall in the transition section is the connection hub between the vertical-section water-cooled wall and the spiral-section water-cooled wall. The water wall in the transition section is composed of tube panels, headers, and connecting pipes. Connection pipes need to be welded between each horizontal tube of the tube panel and the header, and between the tube panel, header, and connecting pipes Whether the combined positioning of the joints is accurate is directly related to the welding quality of the welding joints between them. In addition, due to the large number of ...
