Background

The traditional train unloading scheme uses an excavator to take off a shovel or a grab bucket to unload from the side of the train, and all side doors of a carriage are required to be opened to take off materials on a roadbed. Because the field of view of the excavator is lower than that of the railway carriage, the excavator is basically unloaded blindly, so that a lot of surplus materials are left at the bottom of the carriage, then a lot of manual cleaning of the bottom of the carriage is carried out, and finally the carriage door is sealed. The materials piled on the roadbed belong to the infringed road on the railway, hidden danger exists for the safe operation of the train, the materials are required to be transferred for the second time by a forklift and manual timely cleaning, a large amount of manpower and material resources are consumed by the whole process, the manual workers for cleaning the carriage are mostly large-aged manual workers, and potential safety hazards exist for the workers. Meanwhile, the scraping shovel and the grabbing hopper are used for discharging the impact carriage and the rail blindly, so that great potential safety hazards are left for train operation, and the environment is also greatly polluted by flying dust which is lifted by the materials scraping the ground. Therefore, the traditional unloading mode needs to be replaced by a new scheme due to various factors such as low efficiency, high cost, high labor intensity, high potential safety hazard, environmental protection and the like.

In order to solve the problems, a special excavator for trains with an elevated chassis is generated, and the utility model application with the application number 201911361840.X discloses a special unloading excavator for trains.
