Description

Railway wagons and freight handling systems

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.

With the railway freight car of the present embodiment, the floor 10 of the chassis includes two end floors 11 and an intermediate floor 12 provided between the two end floors 11, and the intermediate floor 12 has a recessed portion. A loading lifting part 20 is arranged on the groove part. When a large truck is loaded, the lifting and lowering part 20 moves from a retracted position adjoining the groove to a raised position at the same height as the two end floors 11 . After the truck is driven onto the middle floor 12 of the railway freight car, and after the tires of the truck are on the load-bearing lifting part 20, the load-bearing lifting part 20 is moved from the raised position to the recovery position, and the truck falls into the railway freight car thereupon, thereby completing the process. loading process. Similarly, when large-scale trucks are unloaded, the load lifting unit 20 is moved from the recovery position to the raised position, and after the truck is opened from the floor 10 of the railway wagon, the load lift unit 20 is moved from the raised position to the raised position. The location is reclaimed, completing the uninstall process. Since the large truck falls into the railway freight car, the height of the top surface of the truck is reduced, and the overall size of the railway freight car equipped with the large truck will not exceed the vehicle limit, thereby effectively solving the problem that the railway freight car cannot transport large trucks.

As shown in FIG. 3 a and FIG. 3 b , in the railway freight car of this embodiment, the underframe further includes two side beams 30 . The two side beams 30 are arranged at intervals and parallel to each other, and the two side beams 30 are arranged at two opposite sides of the floor 10 . The arrangement of the two side beams 30 can position the traveling route of the railway freight car during loading and unloading of the railway freight car, and can enhance the bearing capacity of the underframe of the railway freight car.

As shown in FIG. 4 a and FIG. 4 b , in the railway freight car of this embodiment, the load lifting part 20 includes a longitudinal beam 21 and a cross beam 22 . There are two longitudinal beams 21, and the two longitudinal beams 21 are arranged at intervals and parallel to each other. There are multiple cross beams 22 , and the multiple cross beams 22 are arranged at intervals between the two longitudinal beams 21 , and each cross beam 22 is fixedly connected to the two longitudinal beams 21 . On the premise that the bearing capacity of the lifting portion 20 can be ensured, the above structure has a relatively simple structure, saves materials, and is easy to implement. Preferably, the above-mentioned longitudinal beams 21 and cross beams 22 can be shaped steel, and the fixed connection method of the longitudinal beams 21 and the cross beams 22 can be welding, which can effectively enhance the bearing capacity of the lifting and lowering part 20 .

As shown in FIG. 4 a and FIG. 4 b , in the railway freight car of this embodiment, the lifting and lowering part 20 further includes a positioning groove 23 provided on the longitudinal beam 21 and/or the cross beam 22 .

The piston rod of the hydraulic cylinder 50 is arranged correspondingly to the avoidance hole. Moves between retracted and raised positions.

Specifically, when the worker pulls the railway freight car to the designated position of the loading point through the loading line, the cylinder body of the hydraulic cylinder 50 of the hydraulic system is located below the railway freight car (as shown in FIG. 7 ). The piston rod of the hydraulic cylinder 50 corresponds to the avoidance hole on the groove part, and the piston rod of the hydraulic cylinder 50 acts on the backing plate 24 carrying the lifting part 20 through the avoidance hole. The piston rod of the hydraulic cylinder 50 is stretched out to lift the lifting part 20 from the groove. After the lifting part 20 and the end floor 11 are at the same height, the hydraulic cylinder 50 stops. The truck 1 drives onto the floor 10 of the railway wagon (as shown in Figure 8). After the truck 1 stops on the railway freight car, the piston rod of the hydraulic cylinder 50 is retracted, and the load lifting part 20 falls back into the groove part. After the load lifting part 20 and the groove part are attached, the hydraulic cylinder 50 stops acting as shown in Figure 9). The above-mentioned structure can drive the lifting and lowering part 20 to move between the recovery position adhering to the groove part and the lifting position at the same height as the two end floors 11 .
