[0002] With the continuous development of large industrial enterprises such as domestic power plants, steel mills, ports, etc., the demand for raw materials (coal, iron powder, etc.) is increasing, so the railway transportation of raw materials (coal, iron powder, etc.) is becoming more and more frequent. The car dumper system is one of the main ways to unload raw materials (coal, iron powder, etc.) on the railway. As the main equipment of the coal unloading system, the efficiency and stability of the car dumper are directly related to the unloading capacity of the entire car dumper system.

[0003] However, there are still some problems with the hydraulic station of the car tipper, which are mainly manifested in the following three points: First, the existing hydraulic station of the car tipper is mainly integrated inside the car tipper body, and flips with each car body. Since the hydraulic oil tank flips with the main body of the car tipper, the hydraulic oil will be constantly stirred to produce bubbles, and impurities cannot be precipitated. Second, since the hydraulic oil tank needs to flip 175 degrees, the hydraulic oil tank needs to be fully enclosed, and the internal gas and liquid volume is constantly changing. In this case, there is back pressure, which will have a great impact on the stability and life of the hydraulic station. Third, oil leaks frequently and clogs system components. The small space has a great impact on the production cost and production time of the enterprise; the large size and large space occupied are not conducive to subsequent inspection and maintenance.
