[0032] During the use of the device, the motor 7 drives the gear 5 to rotate. The gear 5 is closely engaged with the rack 3, so that the rack 3 moves linearly under the rotation of the gear 5. The movement of the rack 3 is connected with a sliding block 2, and the sliding block 2 is closely connected with the shell 8. When the sliding block 2 moves, the shell 8 also moves. The movement of the shell 8 drives the relative movement of the two clamping jaws 18, so that the distance between the clamping jaws 18 can be adjusted. By arranging the limiting plates 9 on both sides, the safe distance between the clamping jaws 18 can be accurately controlled, so that accidents can be avoided during hoisting. This design can adjust the clamping position according to the specific length of the cross beam during hoisting of cross beams of different lengths, so as to achieve a more balanced stress effect. This not only improves the safety of hoisting, but also ensures the stability of the metal cross beam during hoisting, avoiding damage caused by uneven stress.

[0033] Referring to Figures 3-4 The inside of the shell 8 is fixedly connected with an electric push rod 10, the output end of the electric push rod 10 is fixedly connected with a mounting frame 11, the inside of the mounting frame 11 is rotatably connected with a first connecting plate 12 on both sides, the side wall of the first connecting plate 12 is rotatably connected with a second connecting plate 13, the side of the second connecting plate 13 is fixedly connected with a first movable plate 16, the inside of the shell 8 is fixedly connected with a first connecting rod 14, the side wall of the first connecting rod 14 is rotatably connected with the second connecting plate 13, the inside of the shell 8 is fixedly connected with a second connecting rod 15, the side wall of the second connecting rod 15 is rotatably connected with a second movable plate 17, the side wall of the first connecting rod 14 is rotatably connected with the first movable plate 16, and the clamping jaw 18 is fixedly connected to the outside of the first connecting rod 14 and the second connecting rod 15.

[0034] Under the drive of the electric push rod 10, the mounting frame 11 will experience a change in position, thereby causing the first connecting plate 12 and the second connecting plate 13 to rotate accordingly. This rotation will further bring the first movable plate 16 and the second movable plate 17 into rotary motion. In this process, the first connecting rod 14 and the second connecting rod 15 play a key bearing role, ensuring smooth and stable rotation. With the continuous rotation of the first movable plate 16 and the second movable plate 17, the clamping jaw 18 will also open and close, effectively completing the clamping and fixing of the cross beam, so that the cross beam can be firmly fixed in the desired position.

[0035] Working principle: When operating the device, first hook the two lifting rings 21 on the suspension platform 20 with the lifting device, then start the motor 7 to make the connected gear 5 below it rotate. The gear 5 and the rack 3 are engaged, and the rotation of the gear 5 will cause the two racks 3 at both ends to move relatively, thereby driving the sliding block 2 to follow the movement, and then changing the distance between the two clamping jaws 18.

[0036] Start the electric push rod 10 to drive the mounting frame 11 to move downward, causing the first connecting plate 12 to deflect, which will move one side of the second connecting plate 13. At this time, the other side of the second connecting plate 13 will rotate on the first connecting rod 14 and simultaneously deflect the first movable plate 16, while the first movable plate 16 is deflecting, the second movable plate 17 will also deflect synchronously to ensure the stability of the clamping jaw 18, thereby completing the clamping and fixing of the cross beam.
