[0002] The pneumatic suspension vehicle uses compressed air as its power source and is continuously inflated. After the airbag is fully lifted, an air film will be generated between it and the ground, which can greatly reduce frictional resistance and achieve a state of suspended operation. There is almost no friction with the ground and the resistance is very small. Therefore, only a small force is required to complete the transportation, installation and positioning of the equipment.

[0003] The propulsion and mobility devices currently used in pneumatic suspension vehicles have some disadvantages. They have high requirements for road conditions, do not take into account the passability on more complex terrains, are prone to sinking when encountering puddles and other terrains, have low passability and stability, and are not very versatile.

The air suspension component 10 can form a thin air cushion between the transport equipment and the ground through compressed air, which can not only reduce friction and realize the suspension and smooth movement of objects, but also because of the existence of the air film, the friction between the transport vehicle and the ground is very small, and no large thrust or traction is required when moving heavy objects, which can reduce physical wear on the ground.

[0052] As a further implementation scheme of the above invention: the air suspension disc 1002 includes a mounting plate fixedly arranged at the bottom end of the support column 1001, an annular rubber airbag is installed below the mounting plate, an inflation port connected to the rubber airbag is opened on the mounting plate, and an exhaust port is opened on the rubber airbag.

[0053] When implementing:

[0054] The air suspension component 10 can form a thin air cushion between the handling equipment and the ground through compressed air, which can not only reduce friction and realize the suspension and smooth movement of objects, but also because of the existence of the air film, the friction between the transport vehicle and the ground is very small, and no large thrust or traction is required when moving heavy objects, which can reduce physical wear on the ground. The driving motor 905 on the spiral propulsion mechanism 9 can drive the driven gears 907 on both sides to rotate synchronously through the driving gear 906. When the driven gear 907 rotates, it can drive the two sets of spiral walking wheels 908 to rotate synchronously. The pneumatic suspension vehicle 1 is driven and propelled by the spiral running wheel 908. Compared with the traditional wheel drive, the pneumatic suspension vehicle 1 has higher passability and stability, and has lower requirements on road conditions. It can pass through some complex terrains and is not easy to fall. It is also easy to control the pneumatic suspension vehicle 1 to go and stop. When the spiral running wheel 908 rotates, the pneumatic suspension vehicle 1 moves. When the spiral running wheel 908 stops rotating, the pneumatic suspension vehicle 1 stops immediately without slipping. The pneumatic suspension vehicle 1 can be controlled to go and stop more stably, and the safety is high when transporting goods.

[0055] When the rotating motor 701 on the driving mechanism 7 drives the first driving rod 702 and the second driving rod 703 to rotate forward and reversely, the driving block 704 sleeved on the outside thereof can be driven to move relative to or away from each other. When the driving block 704 moves relative to each other, the pressing slope 705 on the surface can be used to press the linkage mechanism 8 downward. At this time, the linkage mechanism 8 can drive the spiral propulsion mechanism 9 to descend through the connecting column 801. Conversely, when the driving block 704 is controlled to move away from each other, the linkage mechanism 8 will drive the spiral propulsion mechanism 9 to rise and reset under the action of the reset spring 804. The height of the spiral propulsion mechanism 9 can be adjusted, which not only allows the spiral propulsion mechanism 9 to be adjusted according to the inflation state of the air suspension component 10 to achieve better driving and propulsion, but also after the driving and propulsion of the pneumatic suspension vehicle 1 is completed, the spiral propulsion mechanism 9 can be stored and protected.
