[0031] The push rod 31 slides inside the tube 32, and after moving downward, the push rod 31 presses down with the hanger 1, and the pressing action pushes the raised hanger 1, and the sliding beam 33 adjusts its position inside the slide groove 23, and the fixed state is fixed by the fixing component 4.

[0032] In some embodiments, the swing balancing assembly 5 is installed on both sides of the sliding beam 33, including a rotating shaft 52, which is movably installed inside the tube 32, and the outer wall of the rotating shaft 52 is fixedly connected to the limiting plate 51, and the swing balancing assembly 5 and the sliding beam 33 are fixed by a clamping assembly 9.

[0033] After the sliding beam 33 moves to the designated position, the rotating shaft 52 rotates to drive the limiting plate 51 to rotate, and the limiting plate 51 covers the lifting device 1 to limit the position, so as to prevent the lifting device from swinging back and forth.

[0034] In some embodiments, the fixing component 4 includes a second screw barrel 44, which is fixedly connected to the sliding beam 33. The internal thread of the second screw barrel 44 is installed with a screw rod 41, and the outer wall thread of the screw rod 41 is installed with a first screw barrel 42. Push plates 43 are fixedly connected to both sides of the first screw barrel 42. The push plates 43 are connected to the sliding beam 33 through a limiting component 7, and a plug-in component 8 is provided at one end of the screw rod 41.

[0035] The screw rod 41 generates a threaded motion after rotating inside the second screw barrel 44, driving the first screw barrel 42 of the outer wall to displace, and the first screw barrel 42 drives the two push plates 43 to move, and the push plates 43 move straight to the clamping frame 61 to push the clamping frame 61.

[0045] Working principle: The sling 1 initially lifts the cargo to be transported. Due to the different centers of gravity, the lifting state may shake and tilt. The slide beam 33 adjusts its position inside the slide groove 23. The screw 41 rotates inside the second screw barrel 44 to generate a threaded motion, which drives the first screw barrel 42 of the outer wall to move. The first screw barrel 42 drives the two push plates 43 to move. The push plates 43 move straight to the clamping frame 61 and push the clamping frame 61. After the clamping frame 61 is pushed by the push plate 43, it drives the connecting rod 62 to rotate on the installation frame 63. The driving force generated by the clamping frame 61 after being pushed by the screw 41 The clamping mounting frame 22 and the sliding beam 33 are fixed in position on the mounting frame 22. After the screw rod 41 moves, it drives the plug-in assembly 8 to fix the state of the pushing rod 31. The pushing rod 31 slides inside the tube 32. After the pushing rod 31 moves down, it presses down with the hanger 1. The pressing down action pushes the tilted hanger 1. After the screw rod 41 moves, it drives the plug-in assembly 8 to fix the state of the pushing rod 31. After the sliding beam 33 moves to the specified position, the rotating shaft 52 rotates and drives the limit plate 51 to rotate. The limit plate 51 covers the hanger 1 for limiting, so as to prevent the hanger from swinging back and forth.
