Specifically, the mobile power supply and control module 8 controls the air pump 72 in the buffer pressure-bearing structure 7 to be started again, the air pump 72 pumps air from the buffer pressure-bearing air bag 71 through the air guide pipeline 73, so that the buffer pressure-bearing air bag 71 is gradually compressed, and the reinforced concrete pipe 9 is gradually lowered to the placing surface.

And continuously exhausting to further compress the buffer pressure-bearing air bag 71 to be in the minimum volume state, and taking out the buffer pressure-bearing air bag 71 in the minimum volume state from the space formed by the head end and the tail end of the reinforced concrete pipe 9.

The taken-out buffering pressure-bearing air bag 71 is hung in the air bag accommodating groove 231 of the middle box bottom plate 23 of the self-contained box body 21 again through the rope fastener 711.

As shown in fig. 11, an automated vehicle integrated shipping method based on reinforced concrete pipes includes the following steps:

s1: the package body 21 is brought to the shipping position of the reinforced concrete pipe 9, and the reinforced concrete pipe 9 is loaded into the package body 21.

Specifically, under the control action of the mobile power supply and control module 8, the push-pull plate 56 pushes the self-contained box body 21 to be completely separated from the vehicle body structure 1, and further, after the self-contained box body 21 is lowered to the lowest point, the reinforced concrete pipe 9 is loaded on the bearing plate frame 63 located inside the self-contained box body 21.

S2: the self-contained box body 21 is lifted, and the self-contained box body 21 is fixedly connected with the push-pull plate body 56.

Specifically, the mobile power supply and control module 8 controls and starts the first lifting hydraulic cylinder 31 in the first lifting structure 3 and the second lifting hydraulic cylinder 41 in the second lifting structure 4 to extend, so as to lift the self-contained box body 21 to a predetermined height.

The push-pull plate body 56 of the carrying trailer part 12 is corresponding to the self-contained box body 21 through the vehicle body structure 1, and the push-pull plate body 56 is fixedly connected with the self-contained box body 21 through the second fixed lock catch.

S3: the package body 21 is pulled into the vehicle body structure 1 by the push-pull plate body 56.

Specifically, the push-pull plate body 56 pulls the self-contained box body 21 to synchronously displace towards one side direction close to the head 11 of the tractor through the control action of the mobile power supply and the control module 8; and during the displacement of the self-contained box 21, the second lifting hydraulic cylinder 41 in the second lifting structure 4 and the first lifting hydraulic cylinder 31 in the first lifting structure 3 are retracted in sequence, and finally the self-contained box 21 reaches completely the carrier trailer 12.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
