The box prefabrication workstation and its processing technology in the transition section of the steam injection boiler unit

Abstract

The invention provides a steam-injection boiler unit transmission section box body prefabricating work station. The steam-injection boiler unit transmission section box body prefabricating work station comprises a box body frame pairing welding mechanism, a box body frame inner welding seam welding mechanism and an AGV driverless vehicle which are connected in operating sequence; a box body frame component is welded to be a primary frame by the box body frame pairing welding mechanism, the primary frame is transported by the AGV driverless vehicle to the box body frame inner welding seam welding mechanism, the primary frame is welded by the box body frame inner seam-welding welding mechanism, and a finished product frame is formed. By means of the steam-injection boiler unit transmission section box body prefabricating work station, an intelligent, flexible and automatic advanced production technology is introduced into traditional manufacturing industries, the switchover of a high-efficiency, friendly and green production mode is brought, and transformation and upgrading of the traditional industries are achieved.

Description

technical field [0001] The invention relates to the field of production and processing of a steam injection boiler unit, in particular to a box prefabrication workstation for a transition section of a steam injection boiler unit and its processing technology. Background technique [0002] The transition section of the steam injection boiler unit plays the role of connecting the convection section and the radiation section, and cooperates with the rear panel of the steam injection boiler unit to prevent the direct heat of the flame from scouring the convection section tube bundle. The transition section box is a welded structure composed of steel plate, tube plate, angle steel, and channel steel. The welds include internal welds, external welds, and profile intersecting line welds. The material is Q235 and the MAG welding method is adopted. The size of the box body parts in the transition section is large, and many of them need to be welded internally. In the current producti...

AI Technical Summary

Problems solved by technology

The size of the box body parts in the transition section is large, and many of them need to be welded internally. In the current production, manual assembly and manual welding are generally used, which is labor-intensive, unstable in quality, low in efficiency, and high in cost. It requires a lot of manpower, so the quality and efficiency of the transition box welding has become a problem that must be solved in modern production
