[0022] Reference Figures 1-4 A steel trestle lifting device includes a steel trestle body 1, with clamping claws 2 on both sides of the steel trestle body 1, and a PLC controller on the top surface of the steel trestle body 1. It also includes a clamping assembly for clamping the steel trestle body 1, which is located on the top surface of the steel trestle body 1. The clamping assembly includes a support pipe frame 3, which is located on the top surface of the steel trestle body 1. A connecting frame 4 is fixedly installed on the top surface of the support pipe frame 3. Several first fixing plates 5 are fixedly installed on one side of the support pipe frame 3. Two drive motors 6 are located on one side of the support pipe frame 3, and the drive motors 6 are fixedly installed with the first fixing plates 5. The drive motors 6 are electrically connected to the PLC controller. The internal parts of the support pipe frame 3 are movably connected... There are two first movable plates 8. A threaded hole 9 is opened on one side of the first movable plate 8. A threaded post 7 is threadedly connected to the inner circular wall of the threaded hole 9. The threaded post 7 is fixedly installed to one end of the drive shaft of the drive motor 6. A movable chamber 10 is fixedly installed on the bottom surface of the first movable plate 8. The interior of the movable chamber 10 is movably connected to the clamping claw 2. Limiting plates 12 are fixedly installed on both sides of the clamping claw 2. Limiting holes 11 are opened on both sides of the movable chamber 10. The limiting holes 11 are movably connected to the limiting plates 12. A second fixed plate 14 is fixedly installed on both sides of the movable chamber 10. A tension spring 13 is fixedly installed on the bottom surface of the second fixed plate 14. A second movable plate 15 is fixedly installed on the bottom surface of the tension spring 13. The second movable plate 15 is fixedly installed to the limiting plate 12.

[0023] In this embodiment, one side of the support tube frame 3 is fixedly installed with the PLC controller. The top surface and one side of the support tube frame 3 are respectively fixedly installed with a battery pack 20 and a remote control signal receiver 16. Both the battery pack 20 and the remote control signal receiver 16 are electrically connected to the PLC controller. The top surface of the battery pack 20 is provided with a remote controller 21. The top surface of the support tube frame 3 is fixedly installed with two counterweights 19. Several reinforcing plates 17 are fixedly installed inside the support tube frame 3. A support plate 18 is fixedly installed inside the support tube frame 3. The top surface of the clamping claw 2 is fixedly installed with a rubber plate 22.

[0024] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to lift the steel trestle body 1, the counterweight 19 levels the top surface of the support pipe frame 3, keeping the support pipe frame 3 balanced. At this time, the user picks up the remote control 21, connects the connecting frame 4 to the crane hook, and the crane lifts and moves the connecting frame 4 and the support pipe frame 3, moving the support pipe frame 3 to the top surface of the steel trestle body 1. The user then presses the button... Remote controller 21 starts drive motor 6 to drive threaded post 7 to rotate, so that the rotational motion of threaded post 7 and threaded hole 9 is converted into linear motion. The threads on the outside of threaded post 7 are symmetrically arranged, so that several first moving plates 8 move inside the support frame 3, driving the moving chamber 10 and clamping claws 2 to move, thereby causing several clamping claws 2 to unfold and descend to both sides of the steel trestle plate body 1. Then, drive motor 6 is started to drive threaded post 7 to rotate, so that the first moving plates 8 move, driving the moving chamber 10 and clamping claws 2 to move and move to both sides of the steel trestle plate body 1. The clamping mechanism holds and hooks onto both sides of the steel trestle plate 1. Then, the crane is activated, causing the connecting frame 4 to pull the support pipe frame 3, which lifts the steel trestle plate body 1 through the clamping claws 2. This allows for the lifting of steel trestle plate bodies 1 of different widths, making the operation convenient as it eliminates the need for individual hook connections. During lifting, due to gravity, the clamping claws 2 are pulled out from inside the moving chamber 10 and slide within the limiting hole 11 of the limiting plate 12, maintaining a clamping force on the steel trestle plate body 1. This ensures the clamping claws 2 remain firmly clamped. After lifting to the desired position, the remote control 2 is activated. 1. Starting the drive motor 6 releases the clamp on the steel trestle panel 1, thus achieving the effect of lifting the steel trestle panel 1. This allows the moving clamping claw 2 to lift steel trestle panels 1 of different sizes. Furthermore, the remote control 21 controls the clamping of the steel trestle panel 1 automatically, eliminating the need for multiple slings and hooks, making operation more convenient. During the lifting process, the clamping claw 2 moves to one side of the steel trestle panel 1 to maintain clamping force, preventing loosening. This makes it convenient and practical to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
