A connecting rail 36 is fixedly connected between the main rails 32 and 33. A connecting rail 37 is fixedly connected between the main rails 31 and 32. A connecting rail is fixedly connected to one side of the loading / unloading rail 310. A three-way switch 39 is fixedly connected to one side of loading / unloading track 311 (track 5, 38). A slide rail 3 is installed, connecting main tracks 31, 32, and 33 via connecting tracks 34, 35, 36, 37, 38, and the three-way switch 39. Whether loading or unloading is done from loading / unloading track 310 or 311, only one output track on the production line needs to be connected to fill the entire car. This reduces the time required to move the vehicle for adjustment when connecting the three tracks at the rear door 12. Furthermore, by changing the shift fork 312... The system allows goods to be moved between different tracks and can be freely loaded and unloaded from loading / unloading track 1 310 and loading / unloading track 2 311. A fixed frame 2 is provided, and the slide rail 3 is fixed to the top of the cargo box 1 through the gantry frame 21. The goods are suspended by the hook 25 and moved by the cooperation of the pulley 22 and the locking sleeve 23. After the pulley 22 is moved into the gantry frame 21, the pins 27 on both sides are inserted into the slots 28 to limit the pulley 22 and prevent the pulley 22 from shaking in the cargo box 1 when the vehicle moves. At the same time, the pins 27 are fixed to one side of the gantry frame 21 by the spring line 26, which makes it convenient to use.

[0024] Furthermore, a fork 312 is fixedly connected to the connection points of main track 1 31, main track 2 32, main track 33, connecting track 1 34, connecting track 2 35, connecting track 36, connecting track 4 37, connecting track 5 38, three-way turnout 39, loading and unloading track 1 310 and loading and unloading track 2 311. By changing the direction of the fork 312, goods can be transferred between the tracks and can be freely loaded and unloaded from loading and unloading track 1 310 and loading and unloading track 2 311.

[0025] Furthermore, the main track 1 31 and the loading / unloading track 1 310 are interconnected by the connecting track 5 38. The main track 1 31, main track 2 32, main track 3 33 and loading / unloading track 2 311 are interconnected by the three-way turnout 39. Both loading / unloading track 1 310 and loading / unloading track 2 311 are inclined downwards. Loading / unloading track 1 310 is located on top of the rear door 12, and loading / unloading track 2 311 is located on top of the side door 11. Regardless of whether loading / unloading is done from loading / unloading track 1 310 or loading / unloading track 2 311, it is only necessary to connect to the delivery track on one production line to fill the entire car body.

[0026] Furthermore, main rail 1 31 and main rail 2 32 are interconnected by connecting rail 2 35 and connecting rail 4 37, main rail 2 32 and main rail 33 are interconnected by connecting rail 3 36, and main rail 1 31 and main rail 33 are interconnected by connecting rail 1 34. Main rail 1 31, main rail 2 32 and main rail 33 are interconnected by connecting rail 1 34, connecting rail 2 35, connecting rail 3 36, connecting rail 4 37, connecting rail 5 38 and three-way turnout 39. Regardless of whether loading or unloading is carried out from loading / unloading rail 1 310 or loading / unloading rail 2 311, it is only necessary to connect to the shipping rail on one production line to fill the entire car body.

[0027] Furthermore, the main rails 1 (31), 2 (32), and 3 (33) are arranged in parallel, leaving a certain gap between the goods when they are suspended, so that they do not come into contact with each other.

[0028] Furthermore, the gantry frame 21 is fixedly connected to the top of the cargo box 1 through the fixing holes 29 and fixing bolts. The pins 27 are inserted into the slots 28. After the pulley 22 is moved into the gantry frame 21, the pins 27 on both sides are inserted into the slots 28 to limit the pulley 22 and prevent the pulley 22 from shaking inside the cargo box 1 when the vehicle moves.

[0029] Furthermore, the pulley 22 is slidably connected to the top of the slide rail 3, the locking sleeve 23 is fixedly connected to both ends of the fixed rod 24, and the pulley 22 is rotatably connected to the surface of the locking sleeve 23. The goods are moved by the cooperation of the pulley 22 and the locking sleeve 23.

[0030] Working principle: When customers load and unload goods, the goods connect to the outgoing track on the customer's production line at the rear door 12. By adjusting the fork 312 at the three-way switch 39, the goods slide onto main track 1 31, main track 2 32, or main track 33 respectively. During loading, only one outgoing track needs to be connected to fill the entire truck, reducing the time required to move the vehicle for adjustment when connecting the three tracks at the rear door 12. When loading and unloading at each location, the goods on slide rail 3 can move freely between the tracks and can be loaded and unloaded through side door 11 or rear door 12. If goods behind slide rail 3 want to be loaded and unloaded through loading / unloading track 1 310, connecting track 3 36, connecting track 4 37, and connecting track 5 3 can be adjusted. The shift fork 312 at position 8 connects the main track 33 and the loading / unloading track 1 310, thereby moving the goods from the main track 33 along the connecting track 36, connecting track 4 37, and connecting track 5 38 to the loading / unloading track 1 310 for loading and unloading. Other loading and unloading methods are achieved by changing the direction of the shift fork 312, which will not be listed here. In this way, the goods can be transferred between the various tracks and can be freely loaded and unloaded from the loading / unloading track 1 310 and the loading / unloading track 2 311. When loading, the goods are moved by the cooperation of the pulley 22 and the locking sleeve 23. After the pulley 22 is moved into the gantry 21, the pins 27 on both sides are inserted into the slots 28 to limit the pulley 22 and prevent the pulley 22 from shaking in the cargo box 1 when the vehicle moves.
