Description

Storage tank transport wagon {FREIGHT TRAIN FOR TRANPORITNG A STORAGE TANK}

An embodiment of the invention relates to a freight train.

Freight trains are trains organized as freight cars to transport cargo on railroads. Freight trains carry cargo such as containers or tanks. In addition, freight trains transport freight in a state in which a plurality of freight trains are connected in series through a connector. Here, when a freight train derails, a case occurs where the wagon climbs on the connector and strikes another wagon. At this time, the cargo loaded on the wagon is damaged by impact, and particularly, if the cargo is a dangerous object, it may lead to a major accident.

On the other hand, when a freight train carries tanks containing fluids (e.g., sulfuric acid, oil, LPG, etc.), it is difficult to check whether there are residues in the tank, and even if there are residues, it is difficult to collect them. there is a problem. In addition, when the fluid in the tank is frozen in winter, it is difficult to lower it.

Then, the introduced steam moves along the second heating pipe 153-2 and the first heating pipe 153-1 to heat the heat conductive member 151. At this time, since the heat conductive member 151 contacts the storage tank 110, the storage tank 110 is also heated according to the heating of the heat conductive member 151 to melt the frozen fluid in the storage tank 110.

When the heat conduction member 151 is provided in contact with the residual fluid collection unit 141, the residual fluid collection unit 141 is directly heated through the heat conduction member 151, and the lower end of the lowering pipe 133b collects the residual fluid. As provided in the part 141, even when the fluid is frozen due to low temperature, such as in winter, the fluid can be melted and lowered through the lowering pipe 133b.

Although the exemplary embodiments of the present invention have been described in detail above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications may be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should not be determined by the claims to be described later, but also by those equivalents to the claims.
