Technical Field

The invention relates to the technical field of dumper unloading systems, in particular to a novel through type non-split dumper unloading system and an operation method thereof, which are particularly suitable for dumping non-split railway open cars or non-split open top container flatcars or both.

Background

The conventional bulk cargo carried by railway open cars or containers is generally transported by a dumper unloading system, and the through dumper unloading system is a common process mode. Railway wagons or container wagons are divided into derailleurs and non-derailleurs.

At present, a vehicle dumper unloading system without disconnecting a vehicle dumper needs a vehicle dumper running on a laying track to carry out shunting operation on the vehicle to be dumped. The shunting machine and the railway vehicle do not share a rail, and the traction of the railway vehicle is realized through a shunting arm. Because the shunting machine and the railway vehicle do not share a rail, the shunting operation needs to be realized by overcoming larger resistance, the energy utilization rate is low, and the operation cost is higher. The track of the shunting machine needs larger extra space, occupies large area, and additionally needs large investment to build the track foundation of the shunting machine and manufacture track equipment. The disadvantage is more pronounced if the efficiency is improved by the multiple-tuner solution. In addition, the existing dumper unloading system needs manual intervention in individual links, and has low unmanned, automatic and intelligent levels. In addition, the existing dumper unloading system needs other equipment to send the reshuffling to the movable range of the dumper to work.
