Specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

The present disclosure provides an air transport vehicle, comprising: the transport vehicle body and the picking and placing assembly. The picking and placing assembly comprises a frame body 1 arranged below a transport vehicle body and two clamping jaws 2 rotatably connected below the frame body, as shown in fig. 1.

The first direction and the second direction in the present disclosure are defined for clearly explaining the arrangement manner of each structure in the pick-and-place assembly, and as indicated by the arrows in fig. 1, the first direction and the second direction are two directions perpendicular to each other on a horizontal plane.

At least part of the movable lifting rod 3 is configured for abutment with the top of the gripping object and is configured to move relative to the frame body 1 to a height adapted to the top of the gripping object. Referring to fig. 1 and 2, the plurality of movable lifters 3 are densely arranged in the second direction, and the distance between two adjacent movable lifters 3 should be smaller than the minimum length of the holder in the second direction, so as to ensure that the holder can prop up at least one movable lifter 3.

As shown in fig. 1, a certain adjustable space is also arranged above the clamping space, namely between the movable lifting rod 3 and the top plate of the frame body 1, and when the movable lifting rod 3 ascends relative to the frame body, the adjustable space is reduced, so that the clamping space is increased; when the movable lifting rod 3 descends relative to the frame body, the adjustable space is increased, so that the clamping space is reduced. When a large-volume clamping object is clamped in the clamping space, the top of the clamping object can jack up part of the movable lifting rod 3 upwards, so that the clamping space is enlarged to be capable of accommodating the clamping object, and deformation caused by pressing the clamping object is avoided.

When the top of the clamping object is provided with the groove, at least one movable lifting rod 3 which is not jacked to the highest position can exist in the groove, and the at least one movable lifting rod 3 can be matched with the inner wall of the groove, so that the movable range of the clamping object is limited in the second direction.

According to the clamping jaw, the movable lifting rods 3 are arranged above the clamping jaw 2, the movable lifting rods 3 can move to the height matched with the top of the clamping object under the action of the top of the clamping object, the shape of the top of the clamping space can be changed along with the shape self-adaptation of the top of the clamping object, and therefore the clamping object can not be extruded to deform in the clamping process by the taking and placing assembly. In addition, the movable lifting rod 3 which is not lifted by the jacking or the movable lifting rod 3 with smaller jacking lifting amplitude can form a barrier on the clamping object in the second direction, so that the clamping object is prevented from toppling in the picking and placing assembly, meanwhile, the clamping object is prevented from being struggled and falling out in the second direction, and the clamping stability of the picking and placing assembly is improved.

In one embodiment of the present disclosure, the air transporter further comprises a lifting assembly, and the pick-and-place assembly is disposed below the transporter body by the lifting assembly. The lifting assembly is configured to drive the picking and placing assembly to descend to a position matched with the clamping object so as to pick and place the clamping object, and is configured to drive the picking and placing assembly to ascend to a position adjacent to the transport vehicle body so as to transport the clamping object.

When the picking and placing assembly drives the clamping object to rise to a position adjacent to the transport vehicle body, the clamping object is far away from the ground, so that the transport can be realized under the condition of not occupying the ground space. When the clamping object needs to be fetched and placed, the fetching and placing assembly is required to lightly fetch and lightly place the clamping object, the clamping object cannot be directly loosened in the high air, otherwise, the clamping object can be caused to fall down, and the goods are damaged. Therefore, when the clamping object is taken and placed, the lifting assembly drives the taking and placing assembly to descend to a position matched with the clamping object, for example: the height of the storage position of the clamping object, the height of the conveying line of the clamping object, and the like.
