[0002] A document with publication number CN103253518A discloses a logistics pallet stacking bracket. The bracket includes a main body, a lifting device, and a control device. The main body comprises a square top support platform and four columns, with columns located at the four corners of the square top support platform. Vertical grooves are provided at the bottom of the columns, and sliders are installed within the grooves. The lifting device includes a drive motor, guide wheels, and a steel wire rope. The drive motor is located at the top of the square top support platform, and guide wheels are located at the top of the columns. One end of the steel wire rope is fixedly connected to the slider in the groove, and the other end is wound around the drive shaft of the drive motor. The control device includes an upper contact switch, a lower contact switch, an upper infrared photoelectric switch, a bottom infrared photoelectric switch, and a lifting controller. The drive motor, upper contact switch, lower contact switch, upper infrared photoelectric switch, and bottom infrared photoelectric switch are all connected to the lifting controller. The advantages of this design are: pallets can be removed from the bottom, saving time and effort, avoiding pallet damage, and eliminating safety hazards.

[0003] The cargo pallet devices described above and in existing technologies typically have corresponding limit baffles on both sides when placing cargo. These limit baffles are usually driven by a drive mechanism to clamp the cargo. For clamping components driven by a lead screw, a motor drives the drive wheel to rotate, which in turn drives the driven wheel, which in turn drives the lead screw to drive the limit baffles. However, this process lacks a corresponding limit structure to ensure the lead screw's travel during reciprocating movement. Furthermore, the use of a lead screw requires regular lubrication or maintenance, causing inconvenience to workers and impacting cargo transfer. Therefore, improvements and optimizations are needed.
