[0032] Embodiment 1:

[0033] Please combine Figures 1 to 5 As shown, the utility model provides a cargo loading and unloading platform, including: a cross bar 4, a pair of cross bars 4, vertical bars 5 are fixedly mounted on both cross bars 4, and a plurality of first moving wheels 6 are rotatably mounted on each cross bar 4;

[0034] A pair of fixed plates 1 are provided and are located between two cross bars 4, wherein a first screw rod 8 is rotatably installed in one of the vertical rods 5, a first motor 9 is fixedly installed on the vertical rod 5, an output end of the first motor 9 is fixedly connected to one end of the first screw rod 8, and a fixed block 12 is fixedly installed on both fixed plates 1, one end of the first screw rod 8 passes through the interior of one of the fixed blocks 12 and is threadedly connected to the fixed block 12, a first slide rod 10 is fixedly installed in the other vertical rod 5, one end of the first slide rod 10 passes through the interior of the other fixed block 12 and is slidably connected to the fixed block 12, after starting the first motor 9, the first screw rod 8 can be rotated, so that the two fixed plates 1 can be lifted and lowered, and a sliding cavity 11 is provided on the opposite surfaces of the two fixed plates 1;

[0035] The movable plate 2 is arranged between the two fixed plates 1, and the two ends of the movable plate 2 in the width direction are fixedly installed with slide plates 13, and the two slide plates 13 are respectively slidably arranged in the two slide cavities 11, and a driving component is arranged between the fixed plate 1 and the movable plate 2, and the driving component enables the movable plate 2 to move along the length direction of the fixed plate 1;

[0036] The lifting plate 3 is installed on the movable plate 2 in a liftable manner. After the staff moves the transport cart to the side of the loading and unloading platform, the driving component makes the movable plate 2 approach the transport cart and inserts the movable plate 2 between the two supporting arms of the transport cart. At this time, the movable plate 2 is located at the bottom of the goods. The lifting plate 3 is then moved upward to lift the goods on the transport cart so that the goods are no longer supported by the transport cart. The movable plate 2 is then slid back to its original position. After the movable plate 2 is reset, the two fixed plates 1 and the movable plate 2 can be raised together. The staff no longer needs to pull the transport cart to transfer the goods to the loading and unloading platform, thereby reducing the difficulty of the staff in carrying the goods.
