Description

Technical Field

[0001] The utility model relates to the technical field of cantilever structures, and particularly relates to a cantilever structure of a submerged arc welding machine for box girders. Background Art

[0002] The welding methods for steel structures mainly include manual arc welding with electrodes, gas shielded welding, self-shielded welding, submerged arc welding, electro-slag welding, etc. Among them, submerged arc welding has the inherent advantages of stable welding quality, high welding productivity, no arc light and very little fume and dust. The role of the cantilever in the arc welding machine is to adjust the position of the welding torch for precise welding operations.

[0003] A Chinese patent with the publication number CN218396583U discloses a cantilever crane for a welding machine, which includes a column and a cantilever; a base is provided at the bottom end of the column, and a rotating shaft is provided on the side surface of the column.

[0004] Although the above patent can store the cables of the welding machine assembly on the cantilever through the pulley assembly provided on the side surface of the cantilever during use, which can avoid safety accidents such as the cables being punctured during manufacturing production, since the installation fixture is closed, when fixing the cables of the welding machine assembly, the cables need to be inserted into each installation fixture one by one, which not only reduces the speed of the staff installing the welding machine cables, but also makes it inconvenient to quickly remove the cables from the installation fixture when the welding machine fails. Therefore, a new cantilever structure for a box girder submerged arc welding machine is urgently needed to solve these problems. Summary of the Utility Model

[0023] In order to solve the problem that the cantilever structure of the existing box-beam submerged arc welding machine is in use, since the mounting fixture is closed, when fixing the cable of the welding machine assembly, the cables need to be inserted into each mounting fixture one by one, which not only reduces the speed of the workers in installing the welding machine cables, but also makes it inconvenient to quickly remove the cables from the mounting fixture when the welding machine fails. The utility model provides a baffle plate on one side wall of the mounting piece. When the cable of the welding machine assembly needs to be installed in the mounting piece, the pressing block is pressed to shrink it into the fixing groove, and the limiting of the pressing block on the sliding plate can be cancelled. The sliding plate can be rotated on the connecting column to open the mounting piece. After the cable of the welding machine assembly is placed in the mounting piece together, the pressing block is pressed again to shrink it into the fixing groove, and the sliding plate is moved to return to its original position. The pressing block can be loosened to firmly fix the welding machine cable in the mounting piece, which not only improves the speed of the workers in installing the welding machine cables, but also the mounting piece can be quickly opened to remove the cable from the mounting piece after the welding machine fails.
