Automatic welding device for double-sided water-cooled wall welding

Abstract

The invention relates to the technical field of welding equipment, and particularly discloses an automatic welding device for double-sided water-cooled wall welding. The automatic welding device comprises a machine frame, lifting mechanisms, rolling wheel conveying mechanisms, welding mechanisms and an electric control mechanism; and the lifting mechanisms are installed on the inner side above themachine frame, the rolling wheel conveying mechanisms are arranged on the lifting mechanisms, the welding mechanisms are arranged on conveying routes of the rolling wheel conveying mechanisms, and the lifting mechanisms, the rolling wheel conveying mechanisms and the welding mechanisms are controlled by the electrical control mechanism. The automatic welding device has the advantages of being compact in structure and reasonable in arrangement; the welding device is mainly used for welding double-sided water cooling walls in a boiler; the conveying mechanisms of a welding machine is provided with grooving rolling wheels so as to weld flat steels on vertical surfaces of pipes directly, welding do not need to be carried out manually, the automation degree reaches 99%, meanwhile, the weldingperiod is shortened, and the welding quality is improved, the deformation of the pipe is reduced, cost and working difficulty are reduced, and the market competitiveness of a product is improved.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, in particular to an automatic welding equipment used for welding double-sided water-cooled walls of a boiler. Background technique [0002] The water-cooled wall is the main heating part of the boiler. It is composed of several rows of steel pipes and distributed around the boiler furnace. Its interior is flowing water or steam, and the outside receives the heat of the flame of the boiler furnace. Generally, the water-cooled wall is composed of multiple tubes. The traditional welding equipment is to weld the flat steel on the horizontal plane of the pipe to weld the pipe into a pipe row. It is impossible to weld the flat steel on the vertical plane of the pipe. It needs to be manually assembled by the operator and then manually welded. When it comes to steel, a lot of anti-deformation tooling must be done, then manual welding, and then flame correction. [0003] Manual welding has the ...
