In order to achieve the above purpose, the technical scheme of the invention is to provide a shuttle lifting device, which comprises a lifting table arranged on a shuttle chassis, wherein the lifting table is connected with the chassis through a plurality of lifting guide pieces, an air bag is arranged between the lifting table and the chassis, an air charging port and an air discharging port are arranged on the air bag, the air charging port is connected with an air charging device, and the air discharging port is connected with an air valve. The lifting of the lifting platform is realized through the inflation and the exhaust of the air bag, the structure is simpler, and the lifting guide piece enables the lifting platform to be more stable in the lifting process.

The further technical scheme is that the middle part of the upper surface of the underframe is provided with a groove, and the shape of the air bag is matched with the shape of the groove and is arranged in the groove. The grooves play a role in accommodating and protecting the air bags.

Further, the lifting platform comprises a lifting plate or a lifting frame, a buckling edge matched with the edge shape of the groove is arranged at the edge part below the lifting plate or the lifting frame, and a flange corresponding to the buckling edge is arranged at the upper edge of the groove. The lifting plate or the lifting frame can be used as a platform for placing goods, and the buckling edges and the grooves are matched to further ensure the stability of the lifting device in the lifting process, and the air bag can be further protected. The arrangement of the flange prevents the buckling edge from being separated from the groove.

The lifting guide parts are uniformly distributed on the edge of the upper surface of the underframe or arranged at the top angle of the upper surface of the underframe. The lifting guide piece is arranged at the edge of the upper surface of the underframe or the position of the top angle of the upper surface, so that a space can be reserved for the arrangement of the air bag, and the lifting guide function of the lifting guide piece can be better ensured.

Preferably, the lifting guide piece is a guide pipe vertically arranged below the lifting plate or the lifting frame, and the underframe is provided with a guide hole matched with the guide pipe. By adopting the structure, lifting guide can be realized, the structure is relatively simple, and the structure can also ensure stable lifting of goods.

The further technical scheme is that the top surface is provided with a containing groove, and an electromagnet is arranged in the containing groove. The electromagnet is arranged in the accommodating groove at a position corresponding to the installation position of the ferromagnetic component on the lower surface of the transported goods. With this structure, the goods are prevented from falling off due to inertia during the movement.

Further, the edge of the lifting plate or the lifting frame is provided with a lifting fence, the lifting fence is vertically and slidingly arranged on the edge of the lifting plate or the lifting frame, and a fence jacking air bag is correspondingly arranged below the lifting fence. By adopting the structure, the goods can be further prevented from falling off due to inertia in the moving process.

The further technical scheme is that a reset spring is arranged between the lifting table and the underframe, or the reset spring is arranged between the lifting guide pieces. The reset spring is arranged to enable the speed of the lifting platform to be faster when the lifting platform falls in an empty state, so that time is saved.

The air bag is characterized in that a plurality of partitions are arranged in the air bag, the partitions are equidistantly and alternately arranged in the air bag, and the partitions divide the air bag into a plurality of mutually communicated cavities. This structure prevents the lifting device from being unstable due to the partial lifting of the air bag.

The further technical scheme is that each side face of the underframe is provided with a power socket and/or a travel switch. The power socket can supply power to the internal load through direct current, can also be used as a charging port of an internal battery, and the travel switch can realize travel control of the shuttle on the guide rail.

Adopt shuttle elevating system, the structure is simpler, and the elevating platform is more steady in the lift in-process. Because the contact area of the air bag and the lifting platform is large, the stability and the bearing capacity of the lifting device are obviously improved when the air bag is matched with the lifting guide piece to lift the goods. The arrangement of the buckling edge and the groove can further improve the stability of the lifting device during lifting, and the arrangement of the electromagnet and the lifting fence well avoids goods from sliding off the lifting table.
