Railway ballast hopper car with ballast troweling function

Abstract

The invention discloses a railway ballast hopper car with a ballast troweling function. The railway ballast hopper car comprises a car body, a ballast unloading device, a bottom door, a ballast troweling system, an air controlling system, a braking device, a coupler buffer device and a bogie. The ballast troweling system is added on the ballast hopper car, so that the ballast hopper car has the ballast troweling function and trowels the ballasts higher than a rail surface inside and outside a track during ballast unloading, therefore the operating efficiency of the ballast hopper car is improved, the operation safety is ensured, and the vehicle derailment caused by ballast stacking is effectively avoided. The railway ballast hopper car has the basic function of the hopper car and simultaneously realizes the integration of ballast unloading and ballast trowelling.

Description

Technical field [0001] The invention relates to a railway stone ballast hopper car, in particular to a stone ballast hopper car with a ballast leveling function, and belongs to the technical field of railway transportation. Background technique [0002] With the continuous development of China's railway transportation, the number of domestic railway lines has increased year by year, and the new paving and maintenance of lines has increased year by year. The domestic line paving stone ballast is mainly used for the KZ70 type stone ballast hopper car for the new and old line paving. Or to load bulk cargo, the truck can unload on both sides of the track and the inner side of the track. However, this type of stone ballast hopper car does not have the function of shaping stone ballast. After the stone ballast is unloaded, it will naturally accumulate on the inner and outer sides of the track, especially When unloading on the inner side of the track, special attention should be paid to...

Problems solved by technology

[0002] With the continuous development of China's railway transportation, the number of domestic railway lines has increased year by year, and the new laying and maintenance work of the lines has increased year by year. The stone ballast used for laying domestic lines is mainly supplied by KZ70 ballast hopper car for laying new and old lines. Or transport bulk cargo, the car can be unloaded on both sides of the track and inside the track respectively, but this ballast hopper car does not have the function of shaping the ballast, and the ballast is naturally piled up on the inside and outside of the track after unloading, especially When unloading goods on the inner side of the track, special attention should be paid to the amount and speed of unloading ballast, otherwise the accumulation of stone ballast on the inner side of the track is too high, which will easily cause the vehicle to derail
