The invention discloses a cargo carriage sealing mechanism. The cargo carriage sealing mechanism is specifically provided with an on-off valve, a supercharging device and an expansion sealing strip, wherein the expansion sealing strip is a hollow structure. When a clearance between a cargo carriage main body and a dumping door needs to be sealed (such as when the cargo carriage is transporting cargoes), the supercharging device is communicated with the expansion sealing strip by the on-off valve, a pressure medium provided by the supercharging device enters the interior of the expansion sealing strip, and the expansion sealing strip is enlarged under an effect of a pressure so as to block the clearance between the cargo carriage main body and the dumping door. When the clearance between the cargo carriage main body and the dumping door does not need to be sealed (such as in a dumping or non-loaded state), the expansion sealing strip is communicated with a lower pressure environment (such as atmosphere) by the on-off valve, the pressure medium in the expansion sealing strip flows out, and the expansion sealing strip is narrowed. On the basis of the cargo carriage sealing mechanism, the invention further discloses a dump truck with the cargo carriage sealing mechanism.
