Abstract

The invention discloses a railroad box car and a car door opening and closing device thereof. The car door opening and closing device is used for starting horizontal movement of a car door in inner and outer directions and comprises an upper driving mechanism, a lower driving mechanism and a middle driving mechanism, wherein the upper driving mechanism is arranged at the upper part of the car door and is used for pushing the upper part o the car door to horizontally move in the inner and outer directions; the lower driving mechanism is arranged at the lower part of the car door and is used for pushing the lower part of the car door to horizontally move in the inner and outer directions; one end of the middle driving mechanism is connected to the upper driving mechanism, and the other end of the middle driving mechanism is connected to the lower driving mechanism; the middle driving mechanism drives the upper driving mechanism and the lower driving mechanism to synchronously act so as to push the car door to horizontally move. Through the car door opening and closing device, the car door can be pushed and pulled along the car body direction; the horizontal movement of the car door in the inner and outer directions can be started so as to open and close the car door; the car door opening and closing device is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of railway boxcars, in particular to a railway boxcar and a door opening and closing device thereof. Background technique [0002] Boxcar is a general-purpose vehicle in railway wagons, which is widely used to transport various goods. [0003] With the continuous development of the economy, the requirements for the rapidity of cargo transportation are gradually increasing. In the fast box car, the realization of fast loading and unloading of trucks is one of the main functions that need to be developed. [0004] When the boxcar is loading and unloading goods, it is necessary to open and close the door of the boxcar before carrying out the cargo. The door of the boxcar is relatively large and heavy, and it takes time and effort for the operator to open and close the door, which takes up the loading and unloading time and reduces the loading and unloading efficiency. Therefore, the opening and closing devic...
