[0002] At present, when assembling and welding the existing T-shaped steel, it needs to be positioned by multiple positioning devices. After positioning, the workers use welding guns to weld the vertical plate and the horizontal plate of the T-shaped steel. When assembling the T-shaped steel, the workers use many clamps, which is a lot of work. There is a lack of a positioning device that can quickly position the horizontal plate and the vertical plate at the same time and can be transported to the welding station.

[0052] Embodiment 1: The staff lifts the horizontal plate of the T-shaped steel to the top of the positioning conveyor 1 through the aerial crane in the factory, presses the slider of the slide 2 on the side wall of the horizontal plate through a group of horizontal plate clamping slides 2 to position it, and then lifts the vertical plate of the T-shaped steel to the horizontal plate through the aerial crane, and one side of the vertical plate rests on the pulley of the side limit arm 3, and then starts the lifting slide 4 to drive the limit cylinder 5 to move to the specified height and adapt to the vertical plate.

The side limit rollers 28 are used to limit and guide the side walls of the T-shaped steel cross plate to prevent the T-shaped steel cross plate from deviating during transportation. By adjusting the position of the side limit guide rod 27 in the guide hole of the guide block 21, the spacing between the pair of side limit rollers 28 is changed to adapt to T-shaped steel cross plates of different widths.
