[0025] The top of the sling 34 is suspended on the hook 15. The sling 3 is movably connected to the inside of the connecting plate 2. The top of the front and rear ends of the hook 15 is movably hinged with a hinge plate 31. A spring 32 is installed at the top between the hinge plate 31 and the hook 15. A stop block 30 is fixedly connected to the top of the left side of the hook 15. The bottom end of the hinge plate 31 is located on one side of the stop block 30, and the bottom end of the hinge plate 31 is located at the bottom inside the hook 15.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, the spreader beam 13 and chain 11 can bear the vertical component force. In the horizontal direction, the spreader beam 13 can withstand two equal supporting forces to maintain balance. The bottom end of the sling 34 is wrapped around the screw 16, and then the sling 34 is suspended on the hook 15. Using the spreader beam 13 and sling 34 can speed up the material hoisting efficiency, reduce collisions and improve hoisting safety. In addition, the screw 16 can be recycled.
[0027] Mounting holes 8 are provided at the four corners inside the base 1. Mounting bolts 7 are provided inside the mounting holes 8. A reserved groove 9 is provided on the left side inside the base 1. A connecting shaft 28 is fixedly connected to the front and rear ends inside the reserved groove 9. A movable roller 29 is movably connected to the outside of the connecting shaft 28.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, the base 1 is installed in a suitable position by mounting bolts 7 and mounting holes 8. When the winding shaft 4 winds the hanging rope 3, the movable roller 29 can not only limit the winding shaft 4, but also reduce the wear of the winding shaft 4 and prevent the wear of the winding shaft 4 from affecting the service life of the winding shaft 4.
[0029] A fixing block 22 is fixedly connected to the middle position of the top of the inner part of the protective shell 5. A cylinder 23 is installed at the end of the fixing block 22 near the outside. A connecting block 20 is installed at the end of the cylinder 23 near the outside. Mounting blocks 26 are fixedly connected to the front and rear ends of the bottom of the inner part of the protective shell 5. There are two sets of mounting blocks 26. A first movable block 25 and a second movable block 27 are movably installed on the right side of the mounting blocks 26. Movable clamping plates 18 are installed near the outside of the mounting blocks 26 and the second movable block 27. An anti-sliding block 19 is fixedly connected to the end of the movable clamping plate 18 near the middle. Limiting grooves 24 are fixedly connected to the front and rear ends of the top of the inner part of the protective shell 5. A limiting plate 21 is fixedly connected to the right side of the outer part of the winding shaft 4. The top of the connecting block 20 is located inside the limiting groove 24. The top of the connecting block 20 slides back and forth inside the limiting groove 24. The anti-sliding block 19 is located at the front and rear ends of the limiting plate 21. The front end of the second movable block 27 moves at the rear end inside the first movable block 25. The top of the movable clamping plate 18 is movably hinged to the right side of the connecting block 20.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, when the winding shaft 4 stops rotating, the cylinder 23 is activated. The cylinder 23 drives the connecting block 20 to move towards the center, causing the movable clamping plate 18 to move the anti-sliding block 19 closer to the limiting plate 21. This allows the limiting plate 21 to be clamped to prevent the winding shaft 4 from rotating accidentally, which can further improve the safety performance of the lifting device and prevent accidental lifting of the formwork wall column 17 from injuring workers. The limiting slide 24 can limit the connecting block 20 and improve the stability of the moving connecting block 20.
[0031] Working principle: In use, the bottom end of the sling 34 is wound around the screw 16, and then the sling 34 is suspended from the hook 15. The servo motor 6 is started, and the servo motor 6 drives the winding shaft 4 to rotate, causing the winding shaft 4 to wind the lifting rope 3, thus raising the formwork wall column 17. Using the spreader beam 13 and the sling 34 can speed up the material lifting efficiency, reduce collisions, and improve lifting safety. The screw 16 can be retracted. The spreader beam 13 and the chain 11 can bear the vertical component force. In the horizontal direction, the spreader beam 13 can withstand two equal supporting forces to maintain balance. The winding shaft 4 winds the lifting rope 3. The movable roller 29 can not only limit the winding shaft 4, but also reduce the wear of the winding shaft 4 and prevent the wear of the winding shaft 4 from affecting its service life. When the winding shaft 4 stops rotating, the cylinder 23 is activated. The cylinder 23 drives the connecting block 20 to move towards the center, so that the movable clamping plate 18 drives the anti-slip block 19 to approach the limiting plate 21. This can clamp the limiting plate 21 to prevent the winding shaft 4 from rotating accidentally, which can further improve the safety performance of the lifting device and prevent the mold wall column 17 from accidentally lifting and lowering and injuring the staff. The limiting groove 24 can limit the connecting block 20 and improve the stability of the movement of the connecting block 20.
