Abstract

The invention provides a prefabricating working station for convection section frameworks of high-pressure gas injection units. The prefabricating working station comprises a gantry sliding table, a board rack, a profile rack, a manual feeding gripper, a double-layer clamp sliding table, a rectangular coordinate gripper, a sleeve depot, a working lifting table, a framework assembling clamp and a second arc welding robot. The working station is divided into a board (profile) assembling station site, a framework assembling and welding site and a repair welding site, so that assembling and welding of convection section frameworks are achieved; and the prefabricating working station can avoid manual labor and is stable in quality, high in production efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas injection boiler production, in particular to a frame prefabrication workstation of a convection section of a high-pressure steam injection unit. Background technique [0002] The material of the frame parts in the convection section is Q235, and the MAG welding method is adopted. The welds are allowed to be welded in sections, and the outer welds of the frame blocked by the flanges are not allowed to be welded. There are single-layer and double-layer welds, among which the casing welds are single-layer, the outer welds of the steel plates on the four sides of the frame are single-layer, and the rest of the welds are double-layer. On the basis of the overall length and pipe diameter, the outer end surface of the exposed tube sheet is not more than 5mm. The intersecting line weld of the profile is not accessible by the robot, so it needs to be repaired at other workstations. The previous...
