     In conjunction with  FIG. 1 , in some embodiments of the disclosure, the vehicle frame may further include a lifting assembly a, and there may be at least two lifting assemblies disposed opposite to each other in a first direction, and the lower vehicle frame  4  and the upper vehicle frame  3  may be moved close to or away from each other by operating the at least two lifting assemblies a. 
     In some embodiments of the disclosure, the first direction may be the length direction of the container. 
       FIG. 4  is a schematic diagram showing an arrangement of a lifting assembly a on a vehicle frame in accordance with an embodiment of the disclosure.  FIG. 5  is a schematic diagram of a structure of the lifting assembly a. In conjunction with  FIG. 4  and  FIG. 5 , in some embodiments of the disclosure, each lifting assembly a may include a lifting motor  5 , a wire rope  6 , and a movable pulley  7 . There may be two lifting motors  5  disposed opposite to each other in a second direction, and both lifting motors  5  may be fixed to the upper vehicle frame  3 , and the second direction and the first direction are perpendicular. The movable pulley  7  and the lifting motor  5  may be provided correspondingly in one-to-one relation, and the two movable pulleys  7  may be rotatably disposed on the lower vehicle frame  4  in the second direction. The wire rope  6  and the lifting motor  5  as well as the movable pulley  7  may be provided correspondingly in one-to-one relation, and the wire rope  6  can have a first end and a second end. The first end of the wire rope  6  may be wound on an output end of a corresponding lifting motor  5 , and the second end of the wire rope  6  may be wound around a corresponding movable pulley  7 . 
     In some embodiments of the disclosure, the second direction may be in a width direction of the container, and there may be two lifting assemblies a disposed opposite to each other. 
     In some embodiments of the disclosure, the lower vehicle frame  4  and the upper vehicle frame  3  may be fixedly connected or separated by operating the at least two lifting assemblies a, and thus achieving assembly and connection of the vehicle body of an aerial rail container transportation equipment and the container. The specific operations are: the output end of the lifting motor  5  is controlled to be rotated, so that the wire rope  6  of the same assembly is elongated, thereby lowering the movable pulley  7  of the same assembly to drive the lower vehicle frame  4  to a preset height. After completing the assembly of the container with the lower vehicle frame  4 , the output end of the lifting motor  5  may be controlled to rotate in a reverse direction, which enables the wire rope  6  of the same assembly to rise, and thus the movable pulley  7  of the same assembly rises, thereby driving the lower vehicle frame  4  assembled with the container to rise. After the upper vehicle frame and the lower vehicle frame  4  are locked, the assembly and connection of the vehicle frame and the container are completed accordingly. For unloading the container, only contrary operations are needed. 
     In conjunction with  FIG. 4  and  FIG. 5 , in some embodiments of the disclosure, each lifting assembly a can also include two fixed pulleys  8  corresponding to the wire rope  6 . The two fixed pulley  8  may be opposite to each other in the second direction. The two fixed pulleys  8  may be opposite to each other and disposed between the two lifting motors  5 , and the two fixed pulleys  8  may be rotatably disposed on the upper vehicle frame  3 . The second end of the two wire ropes  6  may be respectively wound around a corresponding movable pulley  7  and a corresponding fixed pulley  8 , and the second ends of the two wire ropes  6  may be joined together, so that two lifting motors  5  of the same assembly may be linked and use a wire rope  6  in common. This is for the following reasons: the length of the wire rope may change in use. If each lifting motor has a wire rope, when the wire rope is used for a long time, the lower vehicle frame  4  will be tipped, and there will be an inclination, which is adverse for the locking of the upper vehicle frame  3  and the lower vehicle frame  4  in proximity to each other and is also not conducive to the transportation of the container. In some embodiments of the disclosure, two lifting motors of the same assembly may share a wire rope  6  in common, and thus a self-adaptation can be realized according to the length of the wire rope  6 , which can ensure that the two ends of the lower vehicle frame  4  in the longitudinal direction of the container are in the same height. The maximum possible phenomenon happened on the lower vehicle frame  4  is the tipping in the longitudinal direction of the container. Therefore, the tipping of the lower vehicle frame  4  in the longitudinal direction of the container has minimal adverse effects on the locking of the upper vehicle frame  3  and the lower vehicle frame  4  in proximity to each other, the locking of the lower vehicle frame  4  and the container as well as the transportation of the container. 
     Referring to  FIG. 5 , in some embodiments of the disclosure, a tension sensor  9  may be provided on the two wire ropes  6  joined together, and the tension sensor  9  may be disposed between the two fixed pulleys  8 . The tension sensor  9  can monitor an abnormal state, such as overloading, etc. to ensure the reliability of the assembly and connection of the container with the vehicle body. 
     In conjunction with  FIG. 4  and  FIG. 5 , in some embodiments of the disclosure, the output shaft of each lifting motor  5  may be fixedly provided with a reel  10 , and the first end of the wire rope  6  may be wound on the reel of a corresponding motor. The lifting motor  5  can drive the rotation of the reel  10 , and thus it is possible to realize the winding and unwinding of the wire rope  6  on the reel  10 . 
     In some embodiments of the disclosure, the reel  10  can have a reduction box therein, which can reduce a speed of the reel  10 , so that a lifting and lowering speed of the lower vehicle frame  4  may be reduced to improve the stability in lifting and lowering the lower vehicle frame  4 . 
     In conjunction with  FIG. 4  and  FIG. 5 , in some embodiments of the disclosure, the upper vehicle frame  3  may be provided with a reel holder  11  corresponding to the reel  10  in on-to-one relation, and the reel  10  is rotatably provided on the corresponding reel holder  11 .

     In some embodiments of the disclosure, when the upper vehicle frame  3  and the lower vehicle frame  4  are needed to be locked, the lower vehicle frame  4  can be controlled to rise by the lifting assembly a, so that the locking head  19  of the rotary pin  18  on the lower vehicle frame  4  can pass through the corresponding lock hole  24  on the upper vehicle frame  3 . At this time, the lifting pin  21  is pressed by the upper vehicle frame  3 , and the limit block  22  is pressed synchronously, so that the rotary handle  20  on the lower vehicle frame  4  is unlocked. At this time, the reset spring  23  is in a compressed state. The driving mechanism c is operated to drive the rotary handle  20  to rotate a certain angle, and in turn, the locking head  19  also rotates a certain angle, so that the locking head  19  cannot drop off from the lock hole  24  of the upper vehicle frame  3 . Then the lower vehicle frame  4  is controlled by the lifting assembly a to be lowered by a small height, and then the reset spring  23  is reset to drive the lifting pin  21  and the limit block  22  to be reset. At this time, the limit block  22  engages the rotary handle  20  so that the rotary handle  20  is mechanically caught by the limit block  22 , and thus the upper vehicle frame  3  and the lower vehicle frame  4  are firmly locked. In some embodiments of the disclosure, only contrary operations are needed to separate the upper vehicle frame  3  from the lower vehicle frame  4 . 
     In conjunction with  FIG. 9 , in some embodiments of the disclosure, the locking head  19  may be provided with two cutting faces  25  opposite to each other and two limit projections  26  opposite to each other on its periphery.
