[0028] Example 1

[0029] Please refer to Figure 1-4 The invention discloses a lifting device for hot-rolled steel construction and a method for using the same, comprising a crane 1 and an H-steel 13. A steel wire rope 11 is installed at one end of the crane 1, a hook 12 is installed at the lower end of the steel wire rope 11, first fixing members are fitted on the inner top surfaces of both sides of the H-steel 13, and second fixing members are fitted on both side surfaces of the H-steel 13. The first fixing member includes a clamping plate 1 2 and a clamping plate 21, which are respectively arranged on both sides of the H steel 13. The inner surface of the clamping plate 21 is fixedly connected with a rotating rod 22. The clamping plate 1 2 is inside the clamping plate 21 and is rotatably connected with the rotating rod 22.

The crane 1 starts to work and hangs the hook 12 inside the fixed block 31, and places the clamping plate 1 2 and the clamping plate 21 from top to bottom on both sides of the H steel 13, so that the rough surfaces of the clamping plate 1 2 and the clamping plate 21 are in contact with the inner top surface of the H steel 13. The crane 1 works to pull the fixed block 31 upward to drive the connecting plate 3 and the connecting block 26 fixedly connected to the connecting plate 3 to move upward synchronously, and the connecting block 26 drives the rotating shaft 25 to move synchronously. Under the gravity of the H steel 13, at the same time, due to Because both the rotating plate 1 23 and the rotating plate 24 are rotatably connected to the rotating shaft 25, the rotating shaft 25 moves upward to drive the rotating plate 1 23 and the rotating plate 24 to rotate toward each other around the rotating shaft 25, so that the angle between the rotating plate 1 23 and the rotating plate 24 becomes smaller, and at the same time drives the clamping plate 1 2 and the clamping plate 21 to rotate around the rotating rod 22, so that the clamping plate 1 2 and the clamping plate 21 rotate toward each other around the rotating rod 22, and the lower ends of the clamping plate 1 2 and the clamping plate 21 rotate toward the H steel 13, and under the action of the rough surface, the clamping effect is better. At the same time, because two clamping plates 1 2 and the clamping plate 21 are arranged on both sides of the H steel 13, the stability of the H steel 13 is better and it is not easy to tilt.

[0031] Technical advantage: It realizes the clamping function of H-steel 13.
