A truck door with container door locking device

Abstract

The invention discloses a truck door with a container door locking device. The truck door comprises a left door component, a guide wheel component, a container door locking device, a rubber gasket, a right door component, a pulley component and a rubber door stopper. The right door component is welded by the door frame and the door panel, a container door locking device is installed between the left and right door components, a container door locking device is installed between the right door component and the car body, the container door lock The closing device is composed of a lock head, a lock lever, a lock seat and a handle. Four sets of guide wheels are installed on the upper part of the door, and four sets of pulleys are installed on the lower part of the door. Two sets of upper and lower rubber buffers are respectively installed on both sides of the door. Install rubber gaskets between the doors. The overall structure of the truck door is reasonable, which can not only effectively improve the strength and rigidity of the door itself, reduce welding deformation, improve the anti-expansion ability of the door, but also improve the structural reliability of the door lock mechanism, and facilitate the operation and maintenance of the door.

Description

Technical field: [0001] The invention relates to the technical field of railway transportation equipment, in particular to a door structure of a railway wagon, in particular to a wagon door with a container door locking device. Background technique: [0002] At present, the doors of the general boxcars of railway freight cars use pulleys matched with flat steel guide rails. During use, the guide rails are easily deformed, resulting in inflexible door opening and closing. C-shaped steel door frames are used for waterproofing. The rigidity is insufficient, and the doors are easily deformed. A hasp lock will not be locked tightly due to the deformation of the door frame during use. There is only a rubber buffer door stop on the side of the door, resulting in uneven force on the door hitting the door stop, resulting in serious damage to the pulley. [0003] Therefore, there is an urgent need to seek a new door structure for railway wagons, which can effectively improve the stren...

Problems solved by technology

[0002] At present, the doors of the general-purpose boxcars of railway freight cars use pulleys matched with flat steel guide rails. During use, the guide rails are easily deformed, resulting in inflexible door opening and closing. C-shaped steel door frames are used for waterproofing. The rigidity is insufficient, and the doors are easily deformed. A hasp lock, during use, the door frame will be deformed and the lock will not be tight. There is only one rubber buffer door stopper on the door side, which will cause uneven force on the door hitting the door stopper, resulting in serious damage to the pulley.
