When the transformer substation is built or overhauled, the power grid heavy equipment needs to be detached from a transport vehicle and transported to be installed indoors or under a live line, or removed from the places for loading and transported to be returned to the factory for repair. Because of the limitation of the electrified safety distance or the indoor space size, most of the power grid heavy equipment cannot be carried by adopting special large-scale machines such as a large-scale crane and a forklift, and meanwhile, because a large amount of ground flat irons and embedded parts on the indoor ground are protruded and cable pits are densely distributed, the indoor ground is uneven, and therefore, the power grid heavy equipment cannot be carried in an air cushion mode. In the limited space, the power grid heavy equipment is usually carried by arranging rollers and ground beetles under the equipment and adopting a manual push-pull mode, and the problems of poor operation stability, high safety risk, a plurality of operators, high labor intensity and low operation efficiency exist in the operation modes.

In a general factory or a logistics warehouse, a pallet, a truck, or the like is generally used to convey articles. However, a large-sized trolley with a carrying capacity of more than 10 tons has the characteristics of large size, high cargo bed and self weight, and is not suitable for carrying power grid heavy piece equipment in a narrow space.

The grant bulletin numbers disclosed in the chinese patent literature are: the utility model patent of CN112758571A discloses an omni-directional hidden traction type AGV trolley, and particularly discloses a driving device and driven wheels, wherein the driving device and the driven wheels are arranged on the vehicle body, the number of the driven wheels is four, the four driven wheels are arranged on the periphery of the bottom of the vehicle body, the number of the driving devices is two, and the driving device comprises a steering wheel mounting frame and a steering wheel device which is arranged on the steering wheel mounting frame and is used for providing driving force. The omni-directional hidden traction type AGV trolley adopts a double-steering wheel driving and four movable castor auxiliary supporting mode, and enables steering wheels and a working pavement to keep sufficient adhesive force through a suspension device, so that the AGV has the omni-directional movement capability with accurate driving control, has damping and buffering capabilities, and protects a steering wheel device; in addition, the automatic charging system is simple in structure and high in traction capability, has the capability of manual charging and automatic charging, saves working space, and overcomes the technical defects of the existing latent AGVs.

However, the steering wheel of the omni-directional hidden traction type AGV disclosed in the patent has an independent steering and driving structure, so that the steering wheel has the problems of large size, heavy dead weight, limited use place, high cargo bed and poor stability of conveying operation.

The above information disclosed in the above background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to those of ordinary skill in the art.
