[0025] Specifically, the hanging beam frame 1 can fix the fixing bar 12, and the fixing bar 12 can fix the bidirectional motor 13, which can ensure the smooth operation of the bidirectional motor 13. The bidirectional motor 13 can rotate the rotating rod 14, and the rotation of the rotating rod 14 can be converted into the rotation of the worm 4 through the bevel gear 2 15 and the bevel gear 1 5, which can then drive the worm wheel 3 to rotate. The mutual cooperation between the worm wheel 3 and the worm 4 makes the rotation of the bidirectional screw 2 have a certain self-locking property, which can improve the stability of the equipment. The support bar 11 can disperse the pressure on the hanging beam frame 1, thereby improving the stability of the hanging beam frame 1.

[0026] Reference Figure 1 - Figure 3 , the lower surface of the beam 9 is fixedly connected with a vertical rod 16, the outer wall of the vertical rod 16 is fixedly connected with a diagonal brace 17, and the outer wall of the diagonal brace 17 is fixedly connected to the lower surface of the beam 9;

[0027] Specifically, the diagonal brace 17 can enhance the stability of the hoisting.

[0028] Reference Figure 1 and Figure 4, the interior of the vertical rod 16 is fixedly connected to a connecting column 18, and the bottom end of the connecting column 18 is fixedly connected to a round block 19; the top of the round block 19 is fixedly connected to a movable block 20, and the outer wall of the round block 19 is provided with a cylinder 21; the outer wall of the connecting column 18 is slidably connected to the inside of the cylinder 21, and the inner wall of the cylinder 21 is fixedly connected to a fixed block 22, and the outer wall of the fixed block 22 is slidably connected to the outer wall of the movable block 20; the inner wall of the cylinder 21 is slidably connected to a spring 23, one end of the spring 23 is fixedly connected to the inner wall of the cylinder 21, and the other end of the spring 23 is rotatably connected to the bottom end of the round block 19; the bottom end of the cylinder 21 is fixedly connected to a U-shaped seat 24, the inside of the U-shaped seat 24 is fixedly connected to a rotating column 25, and the outer wall of the rotating column 25 is rotatably connected to a hook 26;

[0029] Specifically, the vertical rod 16 can fix the connecting column 18, the hook 26 is used for lifting, and the spring 23 can reset the cylinder 21 as a whole. The spring 23 rebounds and resets to push the cylinder 21 to drive the fixed block 22 to slide into the inner wall of the movable block 20 fixedly connected to the bottom end of the round block 19 again, thereby ensuring that the hook 26 maintains a certain angle and improves the stability of lifting.

[0030] Working principle: When in use, start the bidirectional motor 13. The bidirectional motor 13 starts, which will prompt the rotating rod 14 to rotate on the inner wall of the fixed bar 12 and drive the bevel gear 2 15 to rotate. The rotation of the bevel gear 2 15 drives the worm 4 to rotate through the bevel gear 1 5, and then the worm gear 3 drives the bidirectional screw rod 2 to rotate inside the hanging beam frame 1. When the bidirectional screw rod 2 rotates, it will prompt the internal threaded slider 6 to move inward, thereby causing the rotating bar 7 to rotate on the outer wall of the internal threaded slider 6 while also rotating on the outer wall of the fixed seat 8, and then push the crossbeam 9 to slide on the inner wall of the limiting groove 10 opened on the inner wall of the hanging beam frame 1 through the fixed seat 8 to adjust the crossbeam 9. During the adjustment process, the crossbeam 9 distributes the force exerted on the crossbeam 9 to the hanging beam frame 1 by sliding on the inner wall of the limiting groove 10, thereby achieving the effect of avoiding the rotating parts from being subjected to downward pressure during lifting, thereby significantly reducing wear, maintaining transmission accuracy, improving operating stability, and reducing equipment maintenance costs. When it is necessary to adjust the lifting angle of the hook 26, it is only necessary to use the U-shaped seat 2 4 drives the cylinder 21 to move upward. During the upward movement of the cylinder 21, the fixed block 22 will slide out from the inner wall of the movable block 20, the connecting column 18 will slide inside the cylinder 21, the spring 23 will be forced to shrink, and the round block 19 will slide on the inner wall of the cylinder 21. When the fixed block 22 completely slides out from the inner wall of the movable block 20, the cylinder 21 is directly driven to rotate by rotating the U-shaped seat 24, thereby causing the outer wall of the round block 19 to rotate on the inner wall of the cylinder 21, and one end of the spring 23 rotates on the inner wall of the cylinder 21. The bottom end of the round block 19 is used to adjust the angle of the hook 26. When the hook 26 is adjusted to the required angle, the hook 26 is no longer pulled downward. At this time, the spring 23 will no longer be subjected to force, and the spring 23 will rebound and reset to push the cylinder 21 to drive the fixed block 22 to slide into the inner wall of the movable block 20 fixedly connected to the bottom end of the round block 19 again, thereby maintaining a certain angle of the hook 26, thereby avoiding irregular swinging of the weight caused by rotation, and helping to keep the weight balanced during the lifting process.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
