The bottom of the hanging plate 10 is provided with multiple groups of limit insertion structures that can be detachably installed. The hanging plate 10 is also provided with a limit fixing structure 20 for fastening and fixing the detachable limit insertion structure; the limit insertion structure includes an insert plate 14 and two insert arms 16 fixedly welded on the bottom of the insert plate 14, and the insert arms 16 are L-shaped. The two insert arms 16 on each insert plate 14 are inserted into the end of the H-shaped steel. A limit mounting plate 15 is fixedly welded on the top wall of one side of the insert plate 14, and the insert plate 14 and the limit mounting plate 15 are arranged on the side wall of the hanging plate 10.

[0029] like Figure 5 , Figure 4 and Figure 6 As shown, a slot 12 is provided on the bottom wall of one side of the hanging plate 10, and a limited installation slot 13 is provided in the wall of the hanging plate 10 above the slot 12. A limited installation plate 15 is engaged in the limited installation slot 13, and a plug plate 14 is engaged in the slot 12. The plug plate 14 and the limited installation plate 15 are arranged in an up-and-down staggered state, and one end of the limited installation plate 15 away from the limited installation slot 13 extends out from the cavity of the limited installation slot 13. An L-shaped support base 18 is fixedly welded to the bottom of the side of the plug plate 14 away from the insertion arm 16, and the horizontal end of the support base 18 is located below the bottom of the insertion arm 16. A reinforcing rib 19 for reinforcing the support insertion arm 16 is fixedly welded between the support base 18 and the two insertion arms 16. A rubber pad 17 is also fixedly glued to the top wall of the horizontal end of each insertion arm 16.

[0030] like Figure 7 , Figure 3 and Figure 2 As shown, the number of the position-limiting and fixing structures 20 is multiple groups; the position-limiting and fixing structures 20 include a threaded position-limiting sleeve 22, a screw 24 and a position-limiting seat 25, the screw 24 is threadedly connected to the threaded position-limiting sleeve 22, and the screw 24 is rotatably connected to the position-limiting seat 25. The top wall surface of the hanging plate 10 is provided with multiple groups of guide grooves 21, the guide grooves 21 correspond to the position of each position-limiting installation groove 13 up and down, the guide grooves 21 are connected up and down with the corresponding position-limiting installation grooves 13, the top of the threaded position-limiting sleeve 22 is fixedly welded with a mounting plate 23, the mounting plate 23 is fixedly connected to the hanging plate 10 by screws, the threaded position-limiting sleeve 22 extends into the guide groove 21, the screw 24 penetrates the threaded position-limiting sleeve 22, and the position-limiting seat 25 is located below the guide groove 21 cavity. The limit seat 25 and the threaded limit sleeve 22 are simultaneously movably engaged in the guide groove 21, a plurality of first meshing grooves 26 are provided at the bottom of the limit seat 25, and a plurality of second meshing grooves 27 are provided on the top wall of the limit mounting plate 15, and the first meshing grooves 26 and the second meshing grooves 27 can be meshed together up and down.

[0031] When in use, the two lifting ears 11 on a hanging plate 10 are hung and fixed by hooks and steel cables, and the two hooks can lift the two hanging plates 10 through the steel cables. When the H-shaped steel is lifted and transported, the H-shaped steel is generally stacked in an orderly manner. The two insert arms 16 on a plug plate 14 are inserted into the ends of the H-shaped steel, and the middle vertical wall of the H-shaped steel is located between the two insert arms 16. Then the rubber pad 17 contacts the vertical bottom wall of the H-shaped steel. At this time, one side of the H-shaped steel can be lifted. The end is fixed; similarly, the two insert arms 16 on another insert plate 14 are inserted into the ends of the adjacent H-beams, and all the insert arms 16 on the last hanger plate 10 are inserted into the ends of the H-beams, and the insert arms 16 on the other hanger plate 10 are also operated in the same way. It should be noted that the insert arms 16 inserted at both ends of the H-beam need to correspond one to one, so as to ensure that the H-beam is in a stable state when it is lifted, and to avoid the problem of rotation of the H-beam due to unbalanced force when it is lifted.

[0032] Specifically, the multiple sets of plug plates 14 and insert arms 16 provided on the hanging plate 10 of the present invention can be disassembled or replaced. In the process of lifting the H-shaped steel, the number of plug plates 14 to be used can be selected according to the number of H-shaped steels, which makes it convenient to limit and fix the ends of the H-shaped steels, and can improve the lifting efficiency to a certain extent. If a large number of H-shaped steels need to be lifted, the number of installed plug plates 14 can be increased on the hanging plate 10.

[0033] Furthermore, when installing the plug plate 14, the ends of the plug plate 14 and the limit mounting plate 15 are inserted into the slot 12 and the limit mounting groove 13. In order to ensure the stability of the plug plate 14, the screw rod 24 can be rotated by using a tool. When the screw rod 24 rotates, the screw rod 24 can move downward, and the screw rod 24 drives the limit seat 25 to move downward. The first meshing groove 26 at the bottom of the limit seat 25 is meshed with the second meshing groove 27 up and down. In this way, the plug plate 14 and the limit mounting plate 15 can be stably fixed to the hanging plate 10, so as to ensure the stability of the plug arm 16 in lifting the H-shaped steel.
