The traction equipment is used for driving the automatic welding trolley to move forwards and backwards, and is characterized in that: the traction equipment is separated from the automatic welding trolley and is connected with the welding handle line. The lower end of the traction equipment is fixed with the steel structure in an adsorption way through magnetic force. The traction equipment is provided with an immovable driving wheel and a driven wheel which can move up and down. The driven wheel can be used for fixing and clamping a welding handle wire through a bolt and a screw. When the driving wheel rotates under the driving of the motor, the welding handle wire can move back and forth to drive the automatic welding trolley to move back and forth, and finally, the automatic welding of the groove of the steel structure is realized.

The invention has the following advantages and positive effects:

1. according to the invention, the walking mechanism and the driving mechanism of the original automatic welding equipment are separated, and the volume of the automatic welding auxiliary equipment is greatly reduced, so that the novel automatic welding auxiliary equipment can utilize the space of the over-welding hole in the code plate, and the automatic welding equipment shuttles in the space of the over-welding hole, thereby completing the automatic continuous welding of a steel structure.

2. The semicircular tracks spliced by the steel bars are used, so that the semicircular tracks can be tightly attached to the inner edges of the through-welding holes of the stacking plates, and the front and the back of the tracks can be spliced to form long-distance tracks. The track that uses the billet concatenation simultaneously can also guarantee the control to more structure welding process.
