Cutting auxiliary device for interval guide opening of T-shaped stiffened plate

The utility model relates to the technical field of acetylene cutting, in particular to a cutting auxiliary device for a T-shaped stiffened plate interval guide opening, which comprises a clamping groove, a support arm and an auxiliary cutting component, when a plurality of T-shaped stiffened plates arranged on a box girder steel plate at intervals are used for guiding openings, the auxiliary cutting assembly can be installed on the box girder steel plate through the clamping groove and the supporting arm, then a handle in the auxiliary cutting assembly is slowly pushed, a welding hopper provided with a flame gun in the auxiliary cutting assembly moves along the upper portions of the T-shaped stiffened plates arranged at intervals, and in the moving process, the welding hopper is fixed to the upper portion of the box girder steel plate through the clamping groove and the supporting arm. Flames sprayed by the flame gun are used for guiding (cutting) the multiple T-shaped stiffened plates which are arranged at
