[0013] An upper connecting plate is fixedly installed on the inner side of the telescopic rod, and a lower connecting plate is fixedly installed on the inner side of the telescopic base column. The upper connecting plate and the lower connecting plate are arranged parallel to each other, and the lead screw stepper motor is installed on the upper connecting plate and the lower connecting plate.

[0014] As an improved technical solution, the lead screw stepper motor is mounted on the bottom of the lower connecting plate, the lead screw of the lead screw stepper motor passes through the lower connecting plate, and one end of the lead screw is rotatably connected to the bottom of the upper connecting plate.

[0015] As an improved technical solution, the telescopic rod has an integrally formed convex plate, and the inner wall of the sliding groove of the telescopic base column is provided with a limiting groove corresponding to the convex plate, and the limiting groove is adapted to the convex plate. The telescopic rod is installed on the telescopic base column through the convex plate and the limiting groove.

[0016] As an improved technical solution, a PLC controller is installed on the telescopic base column of the telescopic frame. The PLC controller is used to control the start and stop of the drive motor and the lead screw stepper motor, and can separately control the lead screw stepper motor.

[0018] 1. This utility model involves moving the device to the cargo loading and unloading area and securing it using the self-locking function of the casters. Then, the height of the telescopic frame is adjusted by starting a lead screw stepper motor to accommodate different vehicle heights. The lead screw on the stepper motor rotates, driving the upper connecting plate to move. The upper connecting plate then drives the telescopic rod to move until the conveyor belt is moved to a suitable unloading height. During this process, the telescopic rod drives the convex plate to move along the inner cavity of the limiting groove, providing a limiting and guiding function and ensuring stability during movement. The angle is then adjusted according to the vehicle heights on both sides. A PLC controller controls the lead screw stepper motors on both sides to rotate until the height is adjusted to suit the vehicle heights on both sides. This allows for convenient adjustment of the device's height and angle, achieving seamless docking with different vehicle models and facilitating device movement.

[0019] 2. This utility model involves placing goods on a conveyor belt and then starting the drive motor. The output shaft of the drive motor drives the active roller to rotate, which in turn drives the conveyor belt to rotate. The driven roller rotates accordingly and transports the goods until they are transported to another vehicle or a designated location, thus facilitating efficient loading and unloading of goods.

A drive roller 3 and a driven roller 4 are rotatably mounted at both ends of the inner side of the conveyor frame 1, and the drive roller 3 and driven roller 4 are arranged in parallel. The drive roller 3 is connected to the output shaft of the drive motor 2. The conveyor belt 5 is mounted on the outer surfaces of the drive roller 3 and driven roller 4. A hinge seat 6 is fixedly mounted at the bottom of the conveyor frame 1. A telescopic frame is mounted on the fixed seat of the hinge seat 6. The telescopic frame includes a telescopic rod 7, the top of which is mounted on the fixed seat of the hinge seat 6. A telescopic base post 9 is mounted at the end of the telescopic rod 7 away from the hinge seat 6, and the telescopic rod 7 is slidably mounted on the telescopic base post 9. Inside the column 9; an upper connecting plate 8 is fixedly installed on the inner side of the telescopic rod 7, and a lower connecting plate 10 is fixedly installed on the inner side of the telescopic base column 9. The upper connecting plate 8 and the lower connecting plate 10 are arranged in parallel. A lead screw stepper motor 11 is installed on the upper connecting plate 8 and the lower connecting plate 10. The telescopic rod 7 has an integrally formed convex plate 701. A limiting groove 901 corresponding to the convex plate 701 is opened on the inner wall of the sliding groove of the telescopic base column 9, and the limiting groove 901 is adapted to the convex plate 701. The telescopic rod 7 is installed on the telescopic base column 9 through the convex plate 701 and the limiting groove 901. A lead screw stepper motor 11 is fixedly installed on the telescopic frame. The lead screw stepper motor 11 is installed on the bottom of the lower connecting plate 10. The lead screw on the lead screw stepper motor 11 passes through the lower connecting plate 10, and one end of the lead screw is rotatably connected to the bottom of the upper connecting plate 8 to facilitate the adjustment of the height and angle of the device to achieve seamless docking with different vehicle models.

[0032] It also includes casters 12 mounted on the bottom of the telescopic frame, and at least two casters 12 have a self-locking function to facilitate the movement of the device.

[0033] Reference Figures 1-4 A PLC controller 13 is installed on the telescopic base column 9 of the telescopic frame.
