Description

General-purpose gondola car with large axle load

Technical field

The utility model relates to a railway vehicle, in particular to a gondola car, which belongs to the technical field of railway freight car manufacturing.

Background technique

At present, railway gondola cars are mainly used to transport bulk goods such as coal and ore, as well as bulk goods such as steel, timber, machinery and equipment, or boxed goods such as containers. Existing trucks are limited by the load and types of goods. All kinds of goods need special trucks, which have poor versatility, low utilization rate of compartment space, and cannot meet the demand of market transportation volume.

Utility model content

In order to overcome the above-mentioned shortcomings of the existing railway freight cars, the utility model provides a general-purpose gondola car.

The technical solution adopted by the utility model to solve its technical problems is: a general-purpose gondola car with a large axle load for railways, including a car body, a bogie, a brake device and a coupler buffer device; and the end wall; the bottom frame is composed of end beams, corbels, beams, side beams, longitudinal beams, center beams, and bottom plates; the overall upper center plate is installed at the intersection of the center beam and the corbel; the overall upper center plate and the center beam It is connected by blind rivets, and an integral impact seat is installed at the intersection of the end beam and the middle beam.

The beneficial effects of the utility model are:

1. The load of the vehicle is 80t, which is ^10t more than that of the C70 general-purpose gondola car. The single-vehicle transport volume has increased by ^14.3 %. It can meet the shipping needs of fixed-size goods, and the loading capacity can reach 40t, which has strong adaptability.

2. Both the side wall and the end wall adopt the external plate-column structure, and the side transverse belt and the end transverse belt are connected to form a ring-shaped force-bearing structure, which improves the overall rigidity of the vehicle.

3. S450EW high-corrosion-resistant weather-resistant steel is widely used in the vehicle structure, and T4003 stainless steel is used for the door panels. While ensuring the overall rigidity and strength of the vehicle, it reduces the corrosion rate of the vehicle and reduces failures caused by corrosion.

4. The new lower side door structure, T-shaped forged hinges, heightened and wider side column inner reinforcing seat, and secondary locking hasp are adopted to improve the overall rigidity of the door and reduce the failure of the lower side door.

5. The upper cover plate of the beam is canceled to realize the lightweight design of the vehicle.

In a word, the vehicle structure is optimized, the self-weight is reduced, the load is increased, the vehicle has a higher uniform load capacity and collection capacity, and the reliability of the vehicle is improved. Improve the effective utilization rate and transport capacity of the vehicle. Adapt to the requirement of concentrated traction of 10,000 tons of train power. In addition to manual loading and unloading, the truck can also adapt to mechanized unloading operations such as dumpers, and can also meet the requirements of thawing warehouses. It is used to ship bulk goods such as coal and ore, as well as bulk or boxed goods such as steel, wood, mechanical equipment and containers.
