when the limiting bearing plate in the bearing plate part is in a standing state without goods, the helium gas bag in the floating body air bag part respectively drives the air bag bottom plate part and the bearing plate part to move upwards under the action of the performance of the self floating body; the self-adaptive sliding block in the air bag bottom plate part slides and moves upwards along the guide sliding rail in the loading and transporting part, the limiting sliding block in the loading plate part slides and moves upwards along the limiting sliding cavity in the loading and transporting part and stops under the limiting action when the limiting sliding block slides to the top of the limiting sliding cavity, the limiting loading plate stops moving upwards through feedback conduction by the extending positioning rod connected with the limiting sliding block, and then the helium air bag and the sliding mounting plate in the air bag bottom plate part at the bottom of the helium air bag stop moving upwards under the limiting action of the limiting loading plate;
at this time, the load-bearing plate portion, the floating body bag portion, and the bag bottom plate portion are all held in the position to be loaded.
3. The auxiliary transportation method based on the total load of the elevating cargo ship as claimed in claim 2, wherein the specific process of step S2 includes:
when the ship body structure reaches the rated load capacity of the ship body structure in the shipping process, the shipped goods are transferred from the ship body structure and are uniformly placed on the top of the limiting bearing plate of the bearing plate part.
4. The auxiliary transportation method based on the total load of the elevating cargo ship as claimed in claim 3, wherein the specific process of step S3 includes:
along with the increase of the total amount of the cargos loaded and transported on the top of the limiting bearing plate, the gravity generated by the cargos per se is increased and the ascending force automatically generated by the floating body air bag part is gradually overcome, so that the floating body air bag part and the limiting bearing plate gradually move downwards, and meanwhile, the limiting bearing plate synchronously drives the extension positioning rod, the limiting sliding block and the helium bag to move downwards; the limiting slide block gradually slides downwards in the limiting slide cavity; the helium gas bag in the floating body gas bag part stably slides and moves downwards through the sliding action between the self-adaptive sliding blocks at the two sides of the sliding mounting plate at the bottom of the helium gas bag part and the guide sliding rails.

when the cargos to be shipped at the top of the limiting bearing plate reach the predetermined quantity, the limiting bearing plate is under the action of the gravity of the cargos to enable the limiting sliding block to slide to the bottom of the limiting sliding cavity, and the sliding mounting plate at the bottom of the helium gas bag slides to the bottom of the gas bag accommodating cavity in the shipping bearing part; at the moment, the bottom end face of the limiting bearing plate is in contact with the auxiliary shipping deck, meanwhile, the pressure detection end of the touch alarm fixedly connected to the limiting bearing plate synchronously touches and presses the auxiliary shipping deck, and the red and blue alarm lamp in the touch alarm is activated to give an alarm, namely, when the limiting bearing plate reaches a critical position, the weight borne by the floating body airbag part reaches a critical value which can be counteracted by the red and blue alarm lamp.
6. The auxiliary transportation method based on the total load of the elevating cargo ship as claimed in claim 5, wherein the specific process of step S5 includes:
the shipment goods that will place in spacing loading board top take off predetermined weight, and under the body performance effect of float gasbag portion, float gasbag portion can drive spacing loading board again and locate the contact pressure alarm of spacing loading board and shift up, until eliminating the contact pressure effect between contact pressure alarm and the supplementary shipment deck, removes the warning of activation red blue alarm lamp.
7. The auxiliary transportation method based on the total load of the lifted cargo ship as claimed in claim 1, further comprising step S6, wherein the specific process of step S6 comprises:
when the hull structure is transported in a long distance, when the ascending force generated by the floating body performance automatically is weakened along with the reduction of the internal pressure of the floating body air bag part, the limiting bearing plate in the bearing plate part can drive the touch alarm again to touch the auxiliary shipping deck under the action of the gravity of the shipped goods, and the touch alarm automatically generates an alarm.
8. The auxiliary transportation method based on the total load of the lifted cargo ship as claimed in claim 7, further comprising step S6, wherein the specific process of step S6 further comprises:
the goods with the preset weight loaded and transported on the bearing plate part are continuously taken down to reduce the gravity again, the bearing plate part is driven to move upwards again by the ascending force automatically generated by the floating body air bag part, and the touch pressure alarm is deactivated again.
9. The auxiliary transportation method based on the total load of the lifted cargo ship as claimed in claim 7, further comprising step S6, wherein the specific process of step S6 further comprises:
and opening the one-way control valve to lead the compressed helium in the helium tank into the helium bag in the floating body air bag part, gradually returning the gas pressure in the helium bag to the original range, gradually recovering the performance of the floating body to enable the bearing plate part to move upwards, and closing the one-way control valve until the touch pressure alarm stops alarming.
10. The auxiliary transportation method based on the total load of the lifted cargo ship as claimed in claim 1, further comprising step S6, wherein the specific process of step S6 comprises:
and (4) observing the real-time gas pressure value in the helium airbag in the floating body airbag part through the pressure gauge, and judging whether the one-way control valve needs to be opened to introduce helium into the helium airbag.
