Abstract

The invention discloses a welding system for a large thick-wall steel plate. The system comprises a portal type welding mechanism and a steel plate supporting structure. The system is characterized in that the steel plate supporting structure is arranged between two steel rails (1) of the portal type welding mechanism; the steel plate supporting structure is composed of a plurality of groups of carrier rollers (4) and is also equipped with a holding mechanism (5) which is mounted on a lifting hydraulic cylinder (53); an overturning bracket (6) which is hinged to a supporting seat (16) is arranged at one side of the portal type welding mechanism, and the overturning bracket (6) is that the rear surface is connected with a rotating hydraulic cylinder (18), the bottom part is equipped with a steel wire coil (12), and the top part is equipped with a fixed pulley (16); the steel wire coil (12) is connected with a motor (11). With the adoption of the welding system, the abutting, welding, side overturning and other processes in the welding process of a thick steel plate can be done; the stability and reliability in welding and overturning are ensured; workers can operate conveniently; the production efficiency is raised.

Description

technical field [0001] The invention relates to a device for welding large steel plates. Background technique [0002] When welding thick steel plates, the front and back sides need to be welded alternately, and it is very difficult to turn over large thick-walled steel plates. Usually, the steel plates are hoisted and turned over by using a crane. This method has serious safety hazards, and the steel plates are easy to fall off and damage the operation. personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a welding device capable of turning over the steel plate during welding for the problem that the thick steel plate needs to be turned over during welding. [0004] Technical scheme of the present invention is: [0005] A welding system for large-scale steel plates, including a gantry-type welding mechanism and a steel plate support structure, the steel plate support structure is arranged between two rai...
