Narrow gauge flat car

technical field

The utility model relates to a railway freight car, in particular to a narrow-gauge flat car.

Background technique

At present, there are mainly three types of railway lines at home and abroad: standard gauge, wide gauge and narrow gauge. Most areas in my country use standard gauge railway lines, and there are no narrow gauge railway lines, let alone narrow gauge railway transportation equipment. Existing railway flat cars are mainly used to transport goods such as steel, mechanical equipment, containers, etc., and cannot transport bulk goods, and due to the limitation of narrow-gauge railway boundary width, existing railway flat cars cannot bear concentrated loads. In order to meet the needs of domestic and foreign markets, it is urgent to design a narrow-gauge flat car that can meet the requirements of narrow-gauge railways.

In order to further optimize the structure of the flat car and improve its functions, the utility model has also made the following improvements:

The upper and lower edges of the end door and the side door are welded with square tubes, and reinforced columns are welded at intervals on the end door and the side door. The square tube type upper and lower edges of the large section enhance the rigidity of the side door or the end door, reducing the welding deformation of the parts, and at the same time The reinforced column also greatly enhances the strength of the end door panels and side door panels, reducing deformation.

In order to increase the function of the vehicle and ensure that the car body and the bogie are not separated when the whole vehicle is hoisted, a lifting chain is arranged symmetrically between the two sides of the car body and the bogie, and one end of the lifting chain passes through the round pin and the bolt set at the web of the corbel. The lifting lug is hinged, and the other end is connected to the bolster of the bogie, so that the car body does not separate from the bogie.

Four sets of hooks are arranged around the side beam, which can satisfy the lifting of the whole vehicle.

The vertical support is fixed on the end beam, and the opened end door can be placed on the vertical support provided on the end beam so that it forms a horizontal plane with the floor surface.

The structural design of the utility model has the following advantages:

1. By improving the structure of the underframe middle beam, side beams, large beams, and corbels, and adding movable end doors and movable side doors, it can meet the requirements of narrow-gauge railways and meet the requirements of concentrated loads and bulk cargo transportation;

2. The side beam adopts a full-length straight beam structure, which simplifies the manufacturing process, increases the space under the car body, and facilitates the installation, maintenance and repair of the brake device;

3. The end door, side door hinge and hinge seat adopt steel plate assembly and welding structure, which shortens the manufacturing cycle and reduces the manufacturing cost of the whole vehicle compared with the casting structure;

4. The end door and side door adopt square tube welding structure, adding reinforced columns, which simplifies the assembly process and reduces welding deformation;

5. Adopt folding iron stopper and stopper structure, after the side door is closed, the rotation gap of the side door is very small, which prevents the inclination of the side door;

6. Hanging chains are set between the car body and the bogie, and hooks are added around the side beams to increase the vehicle's use function, so that the car body and the bogie will not be separated during land or sea transportation and the car body will not be separated from the bogie when the whole car is transported in the hoistway.

Compared with the prior art, the utility model has the advantages of simple structure, reasonable design, simple manufacturing process and low cost, can adapt to the use requirements of narrow-gauge railways, and meet the requirements of concentrated load and bulk cargo transportation, and has good promotion Value.
