Background

The scrap steel tipping vehicle is a metallurgical vehicle for transporting scrap steel bulk materials to a converter workshop from a stock yard or a wharf and dumping the scrap steel bulk materials into a pit, two transportation modes are mainly used for transporting the scrap steel bulk materials in a steel plant at present, one mode is vehicle transportation, the transportation mode has small single transportation amount, the number of vehicles needing to be equipped is large, and the transportation efficiency is not high; the other one is transportation by railway vehicles, namely the traditional rail type scrap steel transportation vehicle which is characterized by stable operation and large single transportation amount. However, the traditional rail type scrap steel transport vehicle still adopts a locomotive traction operation mode, the traction locomotive is connected with the scrap steel vehicle, the scrap steel is dragged to run on the rail, and the scrap steel does not have a running power device.

In iron and steel enterprises, the quantity matching mode of a traction locomotive and a scrap car is generally one-to-many, namely one locomotive serves a plurality of scrap cars, the scrap car inevitably has a waiting phenomenon after charging, the transportation efficiency is limited, and if one traction locomotive is adopted to serve one scrap car, the cost is too high.

In addition, the conventional rail type scrap steel transport vehicle adopts a scrap steel trough to load scrap steel, and after the scrap steel transport vehicle reaches a specified station, a hoisting crane is needed to hoist the scrap steel trough and dump the scrap steel into a pit. Therefore, the scrap steel vehicle still needs to wait for the cooperation of the hoisting travelling crane when dumping the scrap steel, and sometimes cannot timely dump, so that the operation efficiency is influenced.

With the rapid development of social economy, the steel yield of steel enterprises is also improved year by year, and the demand of steel making on the amount of scrap steel is also continuously increased, so that a transport vehicle is required to have large bearing capacity and high flexibility in organization and scheduling, the traditional locomotive traction operation mode is not suitable for the development demand, and the scrap steel dumping mode is also required to be optimized in order to further improve the operation efficiency of scrap steel dumping, so that how to improve the operation efficiency of the scrap steel transport vehicle and the dumping operation efficiency become a non-negligible issue.
