[0027] The lower wing plate 3 is limited by the lower wing plate limiting wheel 12, the web 4 is limited by the web limiting wheel 13, and the upper wing plate 5 is limited by the first upper wing plate limiting wheel 14 and the second upper wing plate limiting wheel 18. When the lower wing plate 3, the web 4, and the upper wing plate 5 move, they are positioned, and the connection positions are welded to form an H-beam. When the limiting structure needs to be adjusted according to the sizes of the lower wing plate 3, the web 4, and the upper wing plate 5, the first motor 10 drives the lead screw 9 to rotate, so that the lead screw 9 drives the two brackets 11 to move in opposite directions at the same time, and the two positioning mechanisms move in opposite directions at the same time, so that the H-beam can be positioned at the central position, avoiding the position of the H-beam from shifting when positioning the H-beam.

When it is necessary to adjust the limiting structure according to the dimensions of the lower wing plate 3, the web 4, and the upper wing plate 5, the first motor 10 drives the lead screw 9 to rotate, so that the lead screw 9 drives the two brackets 11 to move in opposite directions at the same time, and the two positioning mechanisms move in opposite directions at the same time, which can position the H-shaped steel in the center position and avoid the deviation of the position of the H-shaped steel when positioning the H-shaped steel;

[0031] When the bracket 11 moves in the opposite direction, the second upper wing plate limiting wheel 18 can move horizontally through the third slider 21 and the third chute 20. When the lifting mechanism drives the lifting frame 6 and the first upper wing plate limiting wheel 14 to lift, the second upper wing plate limiting wheel 18 can move vertically through the second chute 16 and the second slider 17. And when it is necessary to adjust the height of the first upper wing plate limiting wheel 14 according to the height of the H-shaped steel, the second motor 25 drives the second reversing gear 26 to rotate. The second reversing gear 26 drives the first reversing gear 24 to rotate through meshing, so that the first reversing gear 24 drives the rotating frame 22 to rotate. The rotating frame 22 drives the lifting frame 6 to lift through the threaded connection formed with the screw rod 23. At the same time, the lifting of the lifting frame 6 is guided by the guide rod 28 and the guide groove 27 to avoid the deviation of the lifting of the lifting frame 6, thereby facilitating the adjustment of the height of the first upper wing plate limiting wheel 14 according to the height of the H-shaped steel.
