[0047] The above-mentioned method of transferring unmanned freight trains based on mutual loading can realize that two empty vehicles can be loaded on one vehicle at the same time through mutual loading of vehicles, which can avoid the situation of empty vehicle transfer or waiting in situ, realize modular transportation, reduce operating costs, and improve product economy. At the same time, it can also greatly improve vehicle turnover efficiency, thereby achieving the core demand of users to reduce the overall number of vehicle purchases and the economy of tolls.

At this point, the back-carrying operation is completed, and the empty vehicle can be transferred.

[0052] For example, please refer to Figure 4 , stacking two second unmanned freight trains in a vertical direction to form a combined vehicle comprising:

At the first back-carrying position, the bearing surface of the first and second unmanned freight trains 20 is connected to the top of the inclined surface 31, and the two are flush or nearly flush with each other.

[0056] In this embodiment, there is no need to manually move the transition platform 30, and it is only necessary to control the first and second unmanned freight trains 20 to travel to the first back-car position, which can save manpower.

[0057] In another embodiment, the transition platform 30 is movable, and the staff places the transition platform 30 at the second back-car position. At the second back-car position, the top of the inclined surface 31 of the transition platform 30 is connected to the load-bearing surface of the first second unmanned freight train 20, and the two are flush or nearly flush with each other.

[0058] In this embodiment, one transition platform 30 can be repeatedly used in the back-car operation, which can save the manufacturing cost of the transition platform 30.

[0059] S212: driving the second second unmanned freight train to travel in reverse along the inclined surface to the bearing surface of the first second unmanned freight train to form a combined vehicle.

The bottom of the inclined surface 31 is flush with or almost flush with the ground 40, and the top is flush with or almost flush with the bearing surface of the first unmanned freight train 10, thereby connecting the bearing surface of the first unmanned freight train 10 and the ground 40.

[0064] In one embodiment, the transition platform 30 is fixed on the ground 40, driving the first unmanned freight train 10 to the third back-carrying position. At the third back-carrying position, the load-bearing surface of the first unmanned freight train 10 is connected to the top of the inclined surface 31, and the two are flush or nearly flush with each other.

[0065] In this embodiment, there is no need to manually move the transition platform 30, and it is only necessary to control the first unmanned freight train 10 to travel to the third back-car position, which can save manpower.

[0066] In another embodiment, the transition platform 30 is movable, and the staff places the transition platform 30 at the fourth back-carriage position. At the fourth back-carriage position, the top of the inclined surface 31 of the transition platform 30 is connected to the bearing surface of the first unmanned freight train 10, and the two are flush or nearly flush with each other.

In this way, the angle of the second movable air guide plate 22 can be adjusted, and the angle between the second movable air guide plate 22 and the second chassis 21 can also be adjusted. The structure for realizing the lifting movement of the second movable air guide plate 22 in the vertical direction, translation movement in the front-back direction, and rotation movement around the horizontal axis is a prior art, and will not be described in detail in this embodiment.

[0086] Before the vehicles are loaded onto each other, the horizontal dimension of the second chassis 21 is first reduced, so that the space occupied by the corresponding second unmanned freight train 20 can be reduced. At the same time, after the first unmanned freight train 10 and the two second unmanned freight trains 20 are loaded onto each other, the length of the entire vehicle can be reduced so that the length of the entire vehicle meets regulatory requirements.

[0087] It should be noted that S213 and S211 may be performed one after the other or simultaneously, which is not limited in this embodiment.

[0088] Optionally, see Figure 2 The first unmanned freight train 10 includes a first chassis 11 and a first movable air deflector 12 arranged on the first chassis 11.

[0097] Optionally, the bearing surface of the first unmanned freight train 10 is provided with a plurality of first limiting grooves, and the bearing surface of the second unmanned freight train 20 is provided with a plurality of second limiting grooves.

[0098] The number of the first limiting groove and the second limiting groove are respectively equal to the number of wheels of the second unmanned freight train 20, and the positions correspond one to one. Generally speaking, the number of wheels of the second unmanned freight train 20 is four, and accordingly, the number of the first limiting groove and the second limiting groove are also four.

[0101] In this way, the positions of the two second unmanned freight trains 20 can be limited to prevent the second unmanned freight trains 20 from being displaced to a large extent during the transfer.

It can also avoid the situation of empty vehicle transfer or waiting in place, realize modular transportation, reduce operating costs, and improve product economy. At the same time, it can also greatly improve vehicle turnover efficiency, thereby realizing the core demand of users to reduce the overall number of vehicle purchases and the economy of tolls.
