Description

Heavy-load driving mechanism, heavy-load transport vehicle and over-span transport vehicle

Technical Field

The utility model belongs to the field of heavy-load transportation, and particularly relates to a heavy-load driving mechanism, a heavy-load transport vehicle and a over-span transport vehicle.

Background

In the production and transportation of large equipment and large components, heavy load vehicles are often required to complete the movement of the large equipment and large components due to their heavy weight. For example: in the production process of trains, train frames are produced in a factory building, and then when the frames move out of the factory building, heavy-load transport vehicles are needed to transport the frames.

Heavy-duty vehicles, i.e., vehicles for heavy-duty transportation, generally include a driving mechanism that provides power to the heavy-duty vehicle so that heavy-duty articles placed on the heavy-duty vehicle can be driven to move. The conventional driving mechanism comprises a driving motor and a driving wheel, wherein the driving motor is in transmission connection with the driving wheel, and when the driving motor works, the driving wheel is transported along with the driving motor to drive the heavy-load transport vehicle to move.

In the prior art, however, a drive shaft is typically used to drivingly connect the drive motor to the drive wheel. Because heavy-duty transport vehicles are required to transport heavy-duty articles, when the driving wheels bear large forces, the driving wheels deform or incline, and therefore, the transmission shafts connected with the driving wheels deform or incline (for example, the transmission shafts incline upwards). When the transmission shaft is deformed or inclined, after long-time transmission, the transmission shaft is cracked or broken, so that the driving motor is disconnected with the driving wheel.

In summary, in the prior art, under a heavy load environment, a problem of disconnection between the driving motor and the driving wheel occurs.
