technical field

The utility model relates to the technical field of railway vehicles, in particular to a railway freight car and a freight loading and unloading system.

Background technique

At present, road transportation is one of the main modes of cargo transportation in our country. However, because road transportation is greatly affected by factors such as weather, terrain, and night driving, the staff usually drives the freight truck to a special railway freight car, and transports the freight truck to the destination by rail. This long-distance, round-the-clock transportation by rail is economical, safe and reliable.

In the above transportation mode, the staff usually leads the railway freight car to the designated position of the loading point through the loading line, and drives the truck 1' through the platform to the floor 10' of the railway freight car (as shown in Figure 1), and completes the loading process . Thereafter, the truck is transported to the destination by rail, and the truck is driven off from the floor 10' of the railway wagon through the platform, and then arrives at the designated place by itself.

In the process of railway transportation, in order to ensure the safety of the truck on the railway line and prevent it from hitting the buildings and equipment adjacent to the line, the outline dimension line that is not allowed to be exceeded is usually stipulated for the railway wagon and the buildings and equipment close to the line (Fig. The dotted line portion shown in 2 shows the outline dimension line). The above outline dimension lines are called rail limits. Basic railway gauges include vehicle gauges and building approach gauges.

Due to the influence of the railway margin, when using the railway freight car in the prior art to transport the truck, if the size of the truck is large, the overall size of the railway freight car with the truck is easy to exceed the vehicle limit (as shown in Figure 2). This causes the above-mentioned transportation methods to only transport small trucks, but not large trucks.
