Abstract

An embodiment of the present invention provides a locking device for the lower side door of a freight open car and a freight open car. The locking device includes a pressing assembly and a connecting assembly. The pressing assembly is connected to the side wall of the freight open car. The pressing assembly is used for The lower door abuts, the connecting assembly is arranged on the side wall, and the connecting assembly is connected with the pressing assembly, so that the pressing assembly abuts against the lower door and the pressing assembly is in a state of pressing the lower door. In the locking device for the lower side door of the open freight car and the open freight car provided by the embodiment of the present invention, the connecting assembly is arranged on the side wall of the open freight car, the pressing assembly abuts against the lower side door, the connecting assembly is connected with the pressing assembly, and the connecting assembly Under the action of the pressure, a pre-tightening force is generated between the pressing assembly and the lower side door, and the pre-tightening force between the pressing assembly and the lower side door can offset the impact force of the goods, thereby avoiding the deformation of the lower side door and avoiding the occurrence of damage to the lower side door of the freight gondola. To solve the problem of leakage, the sealing of the lower side door of the freight gondola is improved.

Description

technical field [0001] The invention relates to the technical field of freight trains, in particular to a locking device for a lower side door of a freight gondola car and a freight gondola car. Background technique [0002] With the development of the railway transportation industry, due to the characteristics of fast transportation and large transportation volume, freight trains have become the main means of land transportation, and open-air freight cars play an important role in the transportation of bulk granular goods. [0003] Freight gondolas are usually provided with passages for loading and unloading goods on the lower side of the gondola. In the prior art, after cargo is loaded in the gondola car, a lower side door made of steel is usually used to close the passage, and the lower side door partially overlaps with the side wall to block the cargo and prevent leakage. [0004] However, during transportation, due to the shaking of the freight open car, the goods are ...
