[0017] (III) Beneficial Effects
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] This anti-sway lifting machinery works by hooking the hook onto the object, starting the first motor to drive the bidirectional threaded rod to rotate, which in turn drives two threaded components to move in opposite directions.

The bottom ends of the two legs of the gantry frame 1 are fixedly connected to a base plate 11. When the hook is hung on the object, the first motor is started to drive the bidirectional threaded rod 7 to rotate. The bidirectional threaded rod 7 drives the two threaded parts 8 to move towards each other. The threaded parts 8 drive the connecting rod 9 and the limiting plate 10 to move, so that the two limiting plates 10 limit and clamp the object. At this time, the servo motor 5 is started to drive the winding roller 3 to rotate, so as to retract the lifting rope 4 and lift the object, thereby preventing the object from swinging in the air and improving the safety of the equipment.
[0029] Reference Figure 4 and Figure 5 The mounting base 2 has a plurality of evenly distributed ball bearings 12 rotatably connected to one end near the gantry frame 1.

[0033] In summary, the working principle and process of this anti-sway lifting machinery are as follows: First, the hook is attached to the object. Then, the first motor is started, driving the bidirectional threaded rod 7 to rotate. The bidirectional threaded rod 7 drives the two threaded components 8 to move in opposite directions. The threaded components 8 drive the connecting rod 9 and the limiting plate 10 to move, thus allowing the two limiting plates 10 to clamp and limit the object. At this time, the servo motor 5 is started, driving the winding roller 3 to rotate, thereby retracting the lifting rope 4 and lifting the object. This prevents the object from swaying in the air, improving equipment safety. The ball bearing 12 is used to reduce... The friction between the mounting base 2 and the gantry frame 1 is reduced to decrease equipment wear and facilitate the movement of the lifting rope 4 and the object. The smooth plate 13 is used to reduce the contact area between the limiting plate 10 and the object, thereby reducing the friction between the limiting plate 10 and the object and improving the smoothness of equipment operation.
