These devices automatically lift or suspend objects based on weight or liquid levels. High-precision sensors sense the state of the object or liquid in real time, and intelligent control systems automatically adjust the balance to ensure stable handling or transportation.

[0003] Related technology can refer to the Chinese patent announcement number CN221587976U, which discloses an automatic lifting device for transporting ventilation ducts, including a base, a guide rail frame, a transport frame, a driving mechanism, a first pulley and a second pulley. The base is provided with a vertically arranged guide rail frame, the driving mechanism is arranged on the base, the transport frame is slidably connected to the guide rail frame and can slide up and down along the guide rail frame, the upper end of the guide rail frame is provided with a first pulley, the transport frame is provided with a second pulley, and the driving end of the driving mechanism is connected to a steel wire rope, the steel wire rope extends upward and passes around the first pulley, then extends downward and passes around the second pulley and is fixed.

[0004] Regarding the above-mentioned related technologies, there is a problem that the connection method between the guide rail and the transport frame for transporting goods is single, and when transporting heavier goods, the lateral force on the guide rail is large, which easily causes the transport frame to shift or tilt.

The two sets of transmission shafts are arranged between the two brackets and are respectively located at the upper end and the lower end of the brackets. The transmission shaft at the upper end of the bracket is coaxially fixedly connected to the output shaft of the drive motor. It also includes multiple sets of sprockets, which are respectively fixed on the two sets of transmission shafts. The number of sprockets on the two sets of transmission shafts corresponds to each other.

The transmission shaft at the upper end of the bracket drives the chain to rotate through the rotation of the sprocket. The rotation of the chain drives the sprocket on the transmission shaft at the lower end of the bracket to rotate, thereby realizing the transmission connection between the transmission shaft at the lower end of the bracket and the transmission shaft at the upper end of the bracket. The support plate moves up and down in the vertical direction through the connecting piece under the action of the chain, and the guide rod limits the horizontal displacement of the support plate, ensuring that the support plate always remains level with the ground, preventing the goods above the support plate from shifting, and improving the stability of the overall device.
